rsquoVE GONE OFF about this ldquobig datardquo thing on more than one occasion abouthow itrsquos mostly marketing hype that vendors hope to turn into sales Butthe whole deal is starting to give me the creeps and itrsquos not just becausethe phrase ldquobig datardquo is being burned into our collective cerebrum withastonishing efficiency

Irsquom still struggling with the idea that therersquos a solution appropriate for pro-cessing big files like high-def digital movies and lots of small files like tweetsGiven the number of vendors already piled onto the big data bandwagon itseems like there are dozens of these so-called solutions floating around So I have trouble getting over that big data hump because any term that refersto completely opposite things simultaneously is questionable in my book

Irsquom not just on a semantical jag here The big data specter goes deeperthan that If you can look past its dual personality a pretty clever play forcorporate egos is at work here ldquoOf course our data is big we wouldnrsquot wantit if it werenrsquotrdquo Itrsquos an emotional ploy that feeds into the kind of self-impor-tance that says everything we dosaycreate is important and should bekeptminedanalyzed Big is beautiful and our data is bigger than yours

Here comes the conspiracy theory part Why is it that so many companiestoday are awash in big data (if they really are) Sure there are a lot moreways of creating stuff than before and everybody seems to be walkingaround with a data-creating machine in each pocket but all of a sudden we have to figure out what to do with the stuff Not too long ago a fewstartups appeared with productsmdashrudimentary maybe but real productsmdashthat could help us pore through all the stuff we stored to determine whatrsquosworth keeping and what needs to be deep-sixed Those data classificationproducts had a lot of promise they came from companies such as AbrevityArkivio FileTek StoredIQ and Kazeon and it looked like they would be thecornerstones of storage management operations from tiering to archiving

The premise was simple You have to know what yoursquove got before you de-cide what you need to do with it

Maybe itrsquos too simple If users get a better grip on what theyrsquore storing andwhat they shouldnrsquot be storing they mightmdashgaspmdashbuy less storage So itwasnrsquot a big surprise that most of those classification vendors disappearedsome simply into the ether and others into the portfolios of (guess who)storage vendors where for the most part theyrsquove just withered away

Apparently knowing what tokeep and what to chuck is a littlethreatening if your company sellsthe storage to stash all that stuffon With those pesky data classifi-cation apps out of the way userscould get back to doing what theyalways do amassing untold heapsof data and buying more disk tostore it

So now you have big data and itrsquos a big problem and vendors are all toohappy to help They have big data storage systems and can supply state-of-the-art big data processing tools so that firms like yours can crunch throughthe piles of data yoursquove been encouraged to keep And as you plow throughthe knee-high drifts of data yoursquoll probably determine your employeesspend too much time tweeting updating their Facebook pages and usingthe SAN to save photos of their kids And yoursquore left to wonder why yoursquorekeeping it all

But data classification isnrsquot the only technology casualty of the bigdata juggernaut A couple of years ago there was buzz around the arrivalof a few products that promised to cut our primary data storage down tosize using deduplication and compression But the two leading startupswere scooped up by megavendors and now primary dedupe and compres-sion sit like a couple of old boxcars on an abandoned railroad siding

And while yoursquore still reeling from the big data drubbing yoursquore gettingfrom vendors watch out for the cloud haymaker theyrsquore about to land Because cloud storage is perfect for big data right And buzzwords tendto get lonely if theyrsquore left on their own 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

Occupy StorageData storage technologies keep getting better but storage vendors may just be up to their old tricks

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

With the advent ofthe new gilded agewersquore seeing vendorsreturn to old trickslike isolating value-add functionality on array controllerswhere it can be used to lock in consumers and lock out competitors

protocols supported only by the vendorrsquos own switches and its ldquosignaturerdquovalue-add storage gear to deliver the ultimate ldquoone-stop-shoprdquo They haveenlisted analysts to preach the gospel of ldquosingle sourcerdquo again One For-rester analyst recently wrote that buying all technology from one vendoris ldquothe only real wayrdquo to drive cost out of storage That couldnrsquot be furtherfrom the truth but itrsquos the mantra vendors are humming into the receptiveears of non-technical decision-makers in the front office of every firm I visit today Many pine for the orderliness of the IBM mainframe data centerof the 1970s while forgetting how the loss of leverage over a vendor trans-lated to extraordinary capital costs in hardware and software and delaysin obtaining needed fixes and changes to products Wersquove forgotten thelessons of the past and are poised to repeat them

Or maybe not I intend to occupy this corner of Storage the magazinefor the foreseeable future and I invite everyone whorsquos interested to bringa tent sleeping bag and their favorite storage issues so we can start anentirely new discussion one about fixing the broken storage model beforeit fixes us This gilded age promises to benefit the 1 of companies thatstill have deep pockets and unlimited budgets for buying storage The other99 need to start exploring viable alternatives 2

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

How our predictionsfor 2011 fared

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

4 Gig FC 1 Gig Ethernet dominate storage networkingNEARLY ALL Storage magazine readers polledmdash92mdashsay their firm is using networkedstorage Forty-five percent have one or two storage networks installed but 27have more than five separate storage networks And while itrsquos no surprise that 4 Gig Fibre Channel (FC) and 1 Gigabit Ethernet (GbE) are the most common net-works (60 and 51 respectively) eyebrows may raise a bit at the number of firmson 10 GbE (35) and 8 Gbps FC (41) Responding companies plan to buy an aver-age of 29 new Ethernet switches and 25 FC switches which should make vendorshappy but theyrsquod probably be disappointed to see the lukewarm reception FibreChannel over Ethernet (FCoE) is getting Positioned as the great consolidator of FCand Ethernet networks FCoE is in production in 13 of reporting firms 8 are test-ing it and 54 checked off ldquono plansrdquo The picture gets a little rosier when peeringinto the future as 47 can envision a mix of FC and Ethernet running over FCoE as their ultimate storage networking configuration mdashRich Castagna

rsquoVE GONE OFF about this ldquobig datardquo thing on more than one occasion abouthow itrsquos mostly marketing hype that vendors hope to turn into sales Butthe whole deal is starting to give me the creeps and itrsquos not just becausethe phrase ldquobig datardquo is being burned into our collective cerebrum withastonishing efficiency

Irsquom still struggling with the idea that therersquos a solution appropriate for pro-cessing big files like high-def digital movies and lots of small files like tweetsGiven the number of vendors already piled onto the big data bandwagon itseems like there are dozens of these so-called solutions floating around So I have trouble getting over that big data hump because any term that refersto completely opposite things simultaneously is questionable in my book

Irsquom not just on a semantical jag here The big data specter goes deeperthan that If you can look past its dual personality a pretty clever play forcorporate egos is at work here ldquoOf course our data is big we wouldnrsquot wantit if it werenrsquotrdquo Itrsquos an emotional ploy that feeds into the kind of self-impor-tance that says everything we dosaycreate is important and should bekeptminedanalyzed Big is beautiful and our data is bigger than yours

Here comes the conspiracy theory part Why is it that so many companiestoday are awash in big data (if they really are) Sure there are a lot moreways of creating stuff than before and everybody seems to be walkingaround with a data-creating machine in each pocket but all of a sudden we have to figure out what to do with the stuff Not too long ago a fewstartups appeared with productsmdashrudimentary maybe but real productsmdashthat could help us pore through all the stuff we stored to determine whatrsquosworth keeping and what needs to be deep-sixed Those data classificationproducts had a lot of promise they came from companies such as AbrevityArkivio FileTek StoredIQ and Kazeon and it looked like they would be thecornerstones of storage management operations from tiering to archiving

The premise was simple You have to know what yoursquove got before you de-cide what you need to do with it

Maybe itrsquos too simple If users get a better grip on what theyrsquore storing andwhat they shouldnrsquot be storing they mightmdashgaspmdashbuy less storage So itwasnrsquot a big surprise that most of those classification vendors disappearedsome simply into the ether and others into the portfolios of (guess who)storage vendors where for the most part theyrsquove just withered away

Apparently knowing what tokeep and what to chuck is a littlethreatening if your company sellsthe storage to stash all that stuffon With those pesky data classifi-cation apps out of the way userscould get back to doing what theyalways do amassing untold heapsof data and buying more disk tostore it

So now you have big data and itrsquos a big problem and vendors are all toohappy to help They have big data storage systems and can supply state-of-the-art big data processing tools so that firms like yours can crunch throughthe piles of data yoursquove been encouraged to keep And as you plow throughthe knee-high drifts of data yoursquoll probably determine your employeesspend too much time tweeting updating their Facebook pages and usingthe SAN to save photos of their kids And yoursquore left to wonder why yoursquorekeeping it all

But data classification isnrsquot the only technology casualty of the bigdata juggernaut A couple of years ago there was buzz around the arrivalof a few products that promised to cut our primary data storage down tosize using deduplication and compression But the two leading startupswere scooped up by megavendors and now primary dedupe and compres-sion sit like a couple of old boxcars on an abandoned railroad siding

And while yoursquore still reeling from the big data drubbing yoursquore gettingfrom vendors watch out for the cloud haymaker theyrsquore about to land Because cloud storage is perfect for big data right And buzzwords tendto get lonely if theyrsquore left on their own 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

Occupy StorageData storage technologies keep getting better but storage vendors may just be up to their old tricks

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

Or maybe not I intend to occupy this corner of Storage the magazinefor the foreseeable future and I invite everyone whorsquos interested to bringa tent sleeping bag and their favorite storage issues so we can start anentirely new discussion one about fixing the broken storage model beforeit fixes us This gilded age promises to benefit the 1 of companies thatstill have deep pockets and unlimited budgets for buying storage The other99 need to start exploring viable alternatives 2

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

Quantum tape libraries lead the fieldAfter finishing well but never winning in past Quality Awards surveysQuantum tape libraries romped through both the enterprise andmidrange categories this time around BY RICH CASTAGNA

Overall ratingsENTERPRISE Quantumrsquosoverall average of 655outpaced tough competi-tors in IBM (637) and Oracle Corp (634) IBMwas particularly tena-cious finishing second in three categories andthird in the other two Oracle rode one second-place finish and consis-tently strong scores to its third-place finish

In winning Quantum showed particular strength in the initial productquality and technical support categories It won the other categorieswith smaller but still convincing margins Coming in second this timeIBM maintained its record of always finishing in the top three since the inception of the enterprise tape library Quality Award surveys

MIDRANGE Quantumbested an even largerfield of competitors in the midrange group andwon by an even largermarginmdash686 to 652mdashover IBM As it did in theenterprise group IBM displayed remarkableconsistency adding thissecond-place finish to its four seconds and onethird in previous surveysOracle placed third with a642 that just trailed IBMBut Quantumrsquos mastery of the midrange was clear with across-the-boardcategory wins in the five rating categories and the only above-700 cate-gory ratings for product features (706) and initial product quality (703) Ina near replay of the enterprise contest IBM came in second in four of thefive categories ceding the second spot to Oracle for initial product quality

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

rsquoVE GONE OFF about this ldquobig datardquo thing on more than one occasion abouthow itrsquos mostly marketing hype that vendors hope to turn into sales Butthe whole deal is starting to give me the creeps and itrsquos not just becausethe phrase ldquobig datardquo is being burned into our collective cerebrum withastonishing efficiency

Irsquom still struggling with the idea that therersquos a solution appropriate for pro-cessing big files like high-def digital movies and lots of small files like tweetsGiven the number of vendors already piled onto the big data bandwagon itseems like there are dozens of these so-called solutions floating around So I have trouble getting over that big data hump because any term that refersto completely opposite things simultaneously is questionable in my book

Irsquom not just on a semantical jag here The big data specter goes deeperthan that If you can look past its dual personality a pretty clever play forcorporate egos is at work here ldquoOf course our data is big we wouldnrsquot wantit if it werenrsquotrdquo Itrsquos an emotional ploy that feeds into the kind of self-impor-tance that says everything we dosaycreate is important and should bekeptminedanalyzed Big is beautiful and our data is bigger than yours

Here comes the conspiracy theory part Why is it that so many companiestoday are awash in big data (if they really are) Sure there are a lot moreways of creating stuff than before and everybody seems to be walkingaround with a data-creating machine in each pocket but all of a sudden we have to figure out what to do with the stuff Not too long ago a fewstartups appeared with productsmdashrudimentary maybe but real productsmdashthat could help us pore through all the stuff we stored to determine whatrsquosworth keeping and what needs to be deep-sixed Those data classificationproducts had a lot of promise they came from companies such as AbrevityArkivio FileTek StoredIQ and Kazeon and it looked like they would be thecornerstones of storage management operations from tiering to archiving

The premise was simple You have to know what yoursquove got before you de-cide what you need to do with it

Maybe itrsquos too simple If users get a better grip on what theyrsquore storing andwhat they shouldnrsquot be storing they mightmdashgaspmdashbuy less storage So itwasnrsquot a big surprise that most of those classification vendors disappearedsome simply into the ether and others into the portfolios of (guess who)storage vendors where for the most part theyrsquove just withered away

Apparently knowing what tokeep and what to chuck is a littlethreatening if your company sellsthe storage to stash all that stuffon With those pesky data classifi-cation apps out of the way userscould get back to doing what theyalways do amassing untold heapsof data and buying more disk tostore it

So now you have big data and itrsquos a big problem and vendors are all toohappy to help They have big data storage systems and can supply state-of-the-art big data processing tools so that firms like yours can crunch throughthe piles of data yoursquove been encouraged to keep And as you plow throughthe knee-high drifts of data yoursquoll probably determine your employeesspend too much time tweeting updating their Facebook pages and usingthe SAN to save photos of their kids And yoursquore left to wonder why yoursquorekeeping it all

But data classification isnrsquot the only technology casualty of the bigdata juggernaut A couple of years ago there was buzz around the arrivalof a few products that promised to cut our primary data storage down tosize using deduplication and compression But the two leading startupswere scooped up by megavendors and now primary dedupe and compres-sion sit like a couple of old boxcars on an abandoned railroad siding

And while yoursquore still reeling from the big data drubbing yoursquore gettingfrom vendors watch out for the cloud haymaker theyrsquore about to land Because cloud storage is perfect for big data right And buzzwords tendto get lonely if theyrsquore left on their own 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

rsquoVE GONE OFF about this ldquobig datardquo thing on more than one occasion abouthow itrsquos mostly marketing hype that vendors hope to turn into sales Butthe whole deal is starting to give me the creeps and itrsquos not just becausethe phrase ldquobig datardquo is being burned into our collective cerebrum withastonishing efficiency

Irsquom still struggling with the idea that therersquos a solution appropriate for pro-cessing big files like high-def digital movies and lots of small files like tweetsGiven the number of vendors already piled onto the big data bandwagon itseems like there are dozens of these so-called solutions floating around So I have trouble getting over that big data hump because any term that refersto completely opposite things simultaneously is questionable in my book

Irsquom not just on a semantical jag here The big data specter goes deeperthan that If you can look past its dual personality a pretty clever play forcorporate egos is at work here ldquoOf course our data is big we wouldnrsquot wantit if it werenrsquotrdquo Itrsquos an emotional ploy that feeds into the kind of self-impor-tance that says everything we dosaycreate is important and should bekeptminedanalyzed Big is beautiful and our data is bigger than yours

Here comes the conspiracy theory part Why is it that so many companiestoday are awash in big data (if they really are) Sure there are a lot moreways of creating stuff than before and everybody seems to be walkingaround with a data-creating machine in each pocket but all of a sudden we have to figure out what to do with the stuff Not too long ago a fewstartups appeared with productsmdashrudimentary maybe but real productsmdashthat could help us pore through all the stuff we stored to determine whatrsquosworth keeping and what needs to be deep-sixed Those data classificationproducts had a lot of promise they came from companies such as AbrevityArkivio FileTek StoredIQ and Kazeon and it looked like they would be thecornerstones of storage management operations from tiering to archiving

The premise was simple You have to know what yoursquove got before you de-cide what you need to do with it

Maybe itrsquos too simple If users get a better grip on what theyrsquore storing andwhat they shouldnrsquot be storing they mightmdashgaspmdashbuy less storage So itwasnrsquot a big surprise that most of those classification vendors disappearedsome simply into the ether and others into the portfolios of (guess who)storage vendors where for the most part theyrsquove just withered away

Apparently knowing what tokeep and what to chuck is a littlethreatening if your company sellsthe storage to stash all that stuffon With those pesky data classifi-cation apps out of the way userscould get back to doing what theyalways do amassing untold heapsof data and buying more disk tostore it

So now you have big data and itrsquos a big problem and vendors are all toohappy to help They have big data storage systems and can supply state-of-the-art big data processing tools so that firms like yours can crunch throughthe piles of data yoursquove been encouraged to keep And as you plow throughthe knee-high drifts of data yoursquoll probably determine your employeesspend too much time tweeting updating their Facebook pages and usingthe SAN to save photos of their kids And yoursquore left to wonder why yoursquorekeeping it all

But data classification isnrsquot the only technology casualty of the bigdata juggernaut A couple of years ago there was buzz around the arrivalof a few products that promised to cut our primary data storage down tosize using deduplication and compression But the two leading startupswere scooped up by megavendors and now primary dedupe and compres-sion sit like a couple of old boxcars on an abandoned railroad siding

And while yoursquore still reeling from the big data drubbing yoursquore gettingfrom vendors watch out for the cloud haymaker theyrsquore about to land Because cloud storage is perfect for big data right And buzzwords tendto get lonely if theyrsquore left on their own 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

Occupy StorageData storage technologies keep getting better but storage vendors may just be up to their old tricks

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

BACKUP ANDRECOVERY

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

BREAKING DOWN THE NUMBERS

bull Oraclersquos two statement winners were a 623 for having knowledgeable third-party partners and a 626 for providing adequate training

bull No support surprises for tape users The higheststatement average for all vendors was a 643 for ldquoVendor supplies support as contractually specifiedrdquo

bull Overall there was only one sub-600 statementscore which suggests vendors are doing a prettygood job of supporting their products

Midrange tape librariesTECHNICAL SUPPORT

BREAKING DOWN THE NUMBERS

bull The top four vendors (Quantum IBM Dell and Oracle)all scored above 600 on all eight statements

bull Vendors may want to revisit their training practicesas the statement with the lowest average score (590)was for providing adequate training

bull As with their enterprise cousins the top supportgrade for all midrange tape libraries was 635 for thevendors delivering support as promised

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

rsquoVE GONE OFF about this ldquobig datardquo thing on more than one occasion abouthow itrsquos mostly marketing hype that vendors hope to turn into sales Butthe whole deal is starting to give me the creeps and itrsquos not just becausethe phrase ldquobig datardquo is being burned into our collective cerebrum withastonishing efficiency

Irsquom still struggling with the idea that therersquos a solution appropriate for pro-cessing big files like high-def digital movies and lots of small files like tweetsGiven the number of vendors already piled onto the big data bandwagon itseems like there are dozens of these so-called solutions floating around So I have trouble getting over that big data hump because any term that refersto completely opposite things simultaneously is questionable in my book

Irsquom not just on a semantical jag here The big data specter goes deeperthan that If you can look past its dual personality a pretty clever play forcorporate egos is at work here ldquoOf course our data is big we wouldnrsquot wantit if it werenrsquotrdquo Itrsquos an emotional ploy that feeds into the kind of self-impor-tance that says everything we dosaycreate is important and should bekeptminedanalyzed Big is beautiful and our data is bigger than yours

Here comes the conspiracy theory part Why is it that so many companiestoday are awash in big data (if they really are) Sure there are a lot moreways of creating stuff than before and everybody seems to be walkingaround with a data-creating machine in each pocket but all of a sudden we have to figure out what to do with the stuff Not too long ago a fewstartups appeared with productsmdashrudimentary maybe but real productsmdashthat could help us pore through all the stuff we stored to determine whatrsquosworth keeping and what needs to be deep-sixed Those data classificationproducts had a lot of promise they came from companies such as AbrevityArkivio FileTek StoredIQ and Kazeon and it looked like they would be thecornerstones of storage management operations from tiering to archiving

The premise was simple You have to know what yoursquove got before you de-cide what you need to do with it

Maybe itrsquos too simple If users get a better grip on what theyrsquore storing andwhat they shouldnrsquot be storing they mightmdashgaspmdashbuy less storage So itwasnrsquot a big surprise that most of those classification vendors disappearedsome simply into the ether and others into the portfolios of (guess who)storage vendors where for the most part theyrsquove just withered away

Apparently knowing what tokeep and what to chuck is a littlethreatening if your company sellsthe storage to stash all that stuffon With those pesky data classifi-cation apps out of the way userscould get back to doing what theyalways do amassing untold heapsof data and buying more disk tostore it

So now you have big data and itrsquos a big problem and vendors are all toohappy to help They have big data storage systems and can supply state-of-the-art big data processing tools so that firms like yours can crunch throughthe piles of data yoursquove been encouraged to keep And as you plow throughthe knee-high drifts of data yoursquoll probably determine your employeesspend too much time tweeting updating their Facebook pages and usingthe SAN to save photos of their kids And yoursquore left to wonder why yoursquorekeeping it all

But data classification isnrsquot the only technology casualty of the bigdata juggernaut A couple of years ago there was buzz around the arrivalof a few products that promised to cut our primary data storage down tosize using deduplication and compression But the two leading startupswere scooped up by megavendors and now primary dedupe and compres-sion sit like a couple of old boxcars on an abandoned railroad siding

And while yoursquore still reeling from the big data drubbing yoursquore gettingfrom vendors watch out for the cloud haymaker theyrsquore about to land Because cloud storage is perfect for big data right And buzzwords tendto get lonely if theyrsquore left on their own 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

Occupy StorageData storage technologies keep getting better but storage vendors may just be up to their old tricks

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

Some data storage managers opt to continue to rely on somewhat

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

rsquoVE GONE OFF about this ldquobig datardquo thing on more than one occasion abouthow itrsquos mostly marketing hype that vendors hope to turn into sales Butthe whole deal is starting to give me the creeps and itrsquos not just becausethe phrase ldquobig datardquo is being burned into our collective cerebrum withastonishing efficiency

Irsquom still struggling with the idea that therersquos a solution appropriate for pro-cessing big files like high-def digital movies and lots of small files like tweetsGiven the number of vendors already piled onto the big data bandwagon itseems like there are dozens of these so-called solutions floating around So I have trouble getting over that big data hump because any term that refersto completely opposite things simultaneously is questionable in my book

Irsquom not just on a semantical jag here The big data specter goes deeperthan that If you can look past its dual personality a pretty clever play forcorporate egos is at work here ldquoOf course our data is big we wouldnrsquot wantit if it werenrsquotrdquo Itrsquos an emotional ploy that feeds into the kind of self-impor-tance that says everything we dosaycreate is important and should bekeptminedanalyzed Big is beautiful and our data is bigger than yours

Here comes the conspiracy theory part Why is it that so many companiestoday are awash in big data (if they really are) Sure there are a lot moreways of creating stuff than before and everybody seems to be walkingaround with a data-creating machine in each pocket but all of a sudden we have to figure out what to do with the stuff Not too long ago a fewstartups appeared with productsmdashrudimentary maybe but real productsmdashthat could help us pore through all the stuff we stored to determine whatrsquosworth keeping and what needs to be deep-sixed Those data classificationproducts had a lot of promise they came from companies such as AbrevityArkivio FileTek StoredIQ and Kazeon and it looked like they would be thecornerstones of storage management operations from tiering to archiving

The premise was simple You have to know what yoursquove got before you de-cide what you need to do with it

Maybe itrsquos too simple If users get a better grip on what theyrsquore storing andwhat they shouldnrsquot be storing they mightmdashgaspmdashbuy less storage So itwasnrsquot a big surprise that most of those classification vendors disappearedsome simply into the ether and others into the portfolios of (guess who)storage vendors where for the most part theyrsquove just withered away

Apparently knowing what tokeep and what to chuck is a littlethreatening if your company sellsthe storage to stash all that stuffon With those pesky data classifi-cation apps out of the way userscould get back to doing what theyalways do amassing untold heapsof data and buying more disk tostore it

So now you have big data and itrsquos a big problem and vendors are all toohappy to help They have big data storage systems and can supply state-of-the-art big data processing tools so that firms like yours can crunch throughthe piles of data yoursquove been encouraged to keep And as you plow throughthe knee-high drifts of data yoursquoll probably determine your employeesspend too much time tweeting updating their Facebook pages and usingthe SAN to save photos of their kids And yoursquore left to wonder why yoursquorekeeping it all

But data classification isnrsquot the only technology casualty of the bigdata juggernaut A couple of years ago there was buzz around the arrivalof a few products that promised to cut our primary data storage down tosize using deduplication and compression But the two leading startupswere scooped up by megavendors and now primary dedupe and compres-sion sit like a couple of old boxcars on an abandoned railroad siding

And while yoursquore still reeling from the big data drubbing yoursquore gettingfrom vendors watch out for the cloud haymaker theyrsquore about to land Because cloud storage is perfect for big data right And buzzwords tendto get lonely if theyrsquore left on their own 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

Occupy StorageData storage technologies keep getting better but storage vendors may just be up to their old tricks

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

ldquoIt will be the catalyst to using LTFSrdquo he said ldquoThen you can see whatrsquoson the tape instead of depending on a database thatrsquos telling you by thetape number or barcode If you have LTFS you can search for a file thesame way you do in a file system LTFS has lots of benefits in that regardrdquo

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

Some data storage managers opt to continue to rely on somewhat

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

The premise was simple You have to know what yoursquove got before you de-cide what you need to do with it

Maybe itrsquos too simple If users get a better grip on what theyrsquore storing andwhat they shouldnrsquot be storing they mightmdashgaspmdashbuy less storage So itwasnrsquot a big surprise that most of those classification vendors disappearedsome simply into the ether and others into the portfolios of (guess who)storage vendors where for the most part theyrsquove just withered away

Apparently knowing what tokeep and what to chuck is a littlethreatening if your company sellsthe storage to stash all that stuffon With those pesky data classifi-cation apps out of the way userscould get back to doing what theyalways do amassing untold heapsof data and buying more disk tostore it

So now you have big data and itrsquos a big problem and vendors are all toohappy to help They have big data storage systems and can supply state-of-the-art big data processing tools so that firms like yours can crunch throughthe piles of data yoursquove been encouraged to keep And as you plow throughthe knee-high drifts of data yoursquoll probably determine your employeesspend too much time tweeting updating their Facebook pages and usingthe SAN to save photos of their kids And yoursquore left to wonder why yoursquorekeeping it all

But data classification isnrsquot the only technology casualty of the bigdata juggernaut A couple of years ago there was buzz around the arrivalof a few products that promised to cut our primary data storage down tosize using deduplication and compression But the two leading startupswere scooped up by megavendors and now primary dedupe and compres-sion sit like a couple of old boxcars on an abandoned railroad siding

And while yoursquore still reeling from the big data drubbing yoursquore gettingfrom vendors watch out for the cloud haymaker theyrsquore about to land Because cloud storage is perfect for big data right And buzzwords tendto get lonely if theyrsquore left on their own 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

Occupy StorageData storage technologies keep getting better but storage vendors may just be up to their old tricks

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

Or maybe not I intend to occupy this corner of Storage the magazinefor the foreseeable future and I invite everyone whorsquos interested to bringa tent sleeping bag and their favorite storage issues so we can start anentirely new discussion one about fixing the broken storage model beforeit fixes us This gilded age promises to benefit the 1 of companies thatstill have deep pockets and unlimited budgets for buying storage The other99 need to start exploring viable alternatives 2

HAT MAKES A storage technology ldquohotrdquo In our book anything new that makesstoring your companyrsquos data a faster better or more efficient process isworthy of the ldquohotrdquo label But it must also represent a new approach todealing with nagging issues Essentially it has to be the answer to thequestion ldquoIf they can send a man to the moon why canrsquot they rdquo

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

ldquoIt will be the catalyst to using LTFSrdquo he said ldquoThen you can see whatrsquoson the tape instead of depending on a database thatrsquos telling you by thetape number or barcode If you have LTFS you can search for a file thesame way you do in a file system LTFS has lots of benefits in that regardrdquo

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

Some data storage managers opt to continue to rely on somewhat

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

iT SEEMS SOMEHOW STRANGE to be publishing my inaugural column in Storagemagazinersquos last issue of 2011 So much ink has already seen paper (or pixelshave been seen on screens) over the last 11 months articles and columnsexpressing findings theories and opinions about the value and benefits ofor limitations and challenges posed by contemporary data storage productsand the way we use them today The situation sets the bar pretty high foranother voice entering the fray to contribute something that will add realvalue to the discussion already in progress

Equally disconcerting is the factthat Irsquom writing this column in ahotel room in Newton Mass notfar from the Hopkinton home ofthe storage hardware marketshare leader EMC Anyone familiarwith my work knows my viewswhich tend to be quite critical of both EMCrsquos products and theirmarketing and sales techniques These views largely pre-date the burgeoningldquogilded agerdquo of storage in which a handful of behemoth vendors havegobbled up most of the smaller fry reducing the options available to consumers for solving storage challenges in the process Irsquove had otheraxes to grind with Hopkinton over my 30-year-plus career in IT and havebeen open and vociferous in expressing my views Frankly I was surprisedand intrigued to be offered a column in this magazine under the circum-stances since the advertising revenue that keeps the publication afloatcomes from precisely those vendors with whose products I so frequentlyfind fault

All of the above notwithstanding I thank you readers for indulging mewith some of your time and I promise to try not to waste any of it I under-stand the challenges that most of you are facing Yoursquore shouldering thework of what used to be many tasked with delivering ever higher service

Occupy StorageData storage technologies keep getting better but storage vendors may just be up to their old tricks

I thank you readersfor indulging me withsome of your time andI promise to try not towaste any of it

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

Or maybe not I intend to occupy this corner of Storage the magazinefor the foreseeable future and I invite everyone whorsquos interested to bringa tent sleeping bag and their favorite storage issues so we can start anentirely new discussion one about fixing the broken storage model beforeit fixes us This gilded age promises to benefit the 1 of companies thatstill have deep pockets and unlimited budgets for buying storage The other99 need to start exploring viable alternatives 2

HAT MAKES A storage technology ldquohotrdquo In our book anything new that makesstoring your companyrsquos data a faster better or more efficient process isworthy of the ldquohotrdquo label But it must also represent a new approach todealing with nagging issues Essentially it has to be the answer to thequestion ldquoIf they can send a man to the moon why canrsquot they rdquo

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

ldquoIt will be the catalyst to using LTFSrdquo he said ldquoThen you can see whatrsquoson the tape instead of depending on a database thatrsquos telling you by thetape number or barcode If you have LTFS you can search for a file thesame way you do in a file system LTFS has lots of benefits in that regardrdquo

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

Barrenrsquos IT department makes use of DataCorersquos high-availability mirroringcapabilities resulting in 10 TB of usable storage in high-availability mode

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

Some data storage managers opt to continue to rely on somewhat

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

levels to your businesses with ever shrinking budgets and at the sametime endeavoring to wrangle a bunch of disparate storage technologiesinto some sort of coherent and manageable resource

I read recently that more than a trillion transactions traverse the wirescables and wireless spectrum of a medium-sized business data centerevery day Those are a trillion miraclesmdashphotons electrons and radio wavesthat successfully complete roundtrips across the most hostile environ-ments imaginable carrying requestsfor data and returning responses tousers and applicationsmdashand you arethe miracle workers who make themhappen

Of course therersquos no recognitionof this and no time to rest on onersquoslaurels even if you were recognizedTruth be told life is hard in storageland and itrsquos about to get a lot harder

With the advent of the new gildedage wersquore seeing vendors return toold tricks like isolating value-addfunctionality on array controllerswhere it can be used to lock in con-sumers and lock out competitors In general this design approach haslimited merit because it inhibits cross-platform manageability increasesdata routing complexity drives up the cost of commodity array compo-nents adds what are usually obscene software licensing costs to the kitand introduces greater risk of failure into the data center environmentEmbedded value-add software vendor engineers have told me is usuallypoorly validated because the interoperability test matrix is simply toocomplex and time consuming to undertake and complete Thus it shouldcome as little surprise that the 3000 companies polled by CA Technologiesearlier this year reported they had accrued more than 127 million hours ofdowntime last year partly due to storage-related outages (The AvoidableCost of Downtime May 2011 CA Technologies)

And in this gilded age it goes without saying that a proper behemothstorage vendor must also offer a ldquocloud architecturerdquo Using proprietaryhardwaresoftware stacks each one is seeking to advance its own main-frame ldquomini-merdquo that combines a server hypervisor with a set of network

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

ldquoIt will be the catalyst to using LTFSrdquo he said ldquoThen you can see whatrsquoson the tape instead of depending on a database thatrsquos telling you by thetape number or barcode If you have LTFS you can search for a file thesame way you do in a file system LTFS has lots of benefits in that regardrdquo

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

HAT MAKES A storage technology ldquohotrdquo In our book anything new that makesstoring your companyrsquos data a faster better or more efficient process isworthy of the ldquohotrdquo label But it must also represent a new approach todealing with nagging issues Essentially it has to be the answer to thequestion ldquoIf they can send a man to the moon why canrsquot they rdquo

We found six technologies that can store massive amounts of data effortlessly perform at lightning speeds turn old assets like tape andserver disks into something new and put the cloud within reach of enterprise data centers

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

BACKUP ANDRECOVERY

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

How our predictionsfor 2011 fared

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

As usual our hot techs mix equal parts of cutting-edge cool and practi-cality Object-based storage throws out tradition and replaces file systemswith a simplified flat-file approach to managing data Linear Tape FileSystem goes the other way and adds a file system to tapes to make themlook like disks Both are timely arrivals on a storage scene thatrsquos begin-ning to buckle under the weight of too much data

With multi-level cell (MLC)flash storage the medium is themessage as rapidly developingtechnologies have turned thisrelatively inexpensive type of solid-state storage into an enterprise mainstay But even asflash hogs the headlines server-based storage is making a come-back with innovative ways toshare directly attached assets

Last year we predicted thatcloud storage services wouldemerge but this year wersquore putting a finer point on that prediction and singling out two technologies that will make it easy to inte-grate on-premises systems with cloud-based storage resources that essen-tially treat the cloud as just another tier

OBJECT-BASED STORAGENetwork-attached storage (NAS) isnrsquot the only way to handle file storageItrsquos not even always the best way

Object-based storage systems are gaining a lot of attention and startingto make inroads as an alternative to scale-out NAS Object storage has unlimited scalability is less reliant on processing and high-speed networksand is a fundamental building block of public and private cloud storage

But itrsquos not perfect Object storage generally isnrsquot a high-performancetechnology and it lacks the standardization of file systems making ittougher to move from one vendorrsquos object storage system to another Itrsquosalso poorly suited to data that frequently changes and often eats up morestorage capacity than traditional data storage But the technology makes itpossible to archive huge datastores cheaper with less power and within asmaller footprint than high-performance NAS

With multi-level cell(MLC) flash storage themedium is the messageas rapidly developingtechnologies haveturned this relativelyinexpensive type ofsolid-state storage intoan enterprise mainstay

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

Some data storage managers opt to continue to rely on somewhat

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

Page 14: Storage magazine Online December 2011 -- Six Hot Storage Technologies for 2012

Object storage uses unique identifiers to access data instead of physicaladdresses The data is accessed based on the name and unique ID thestorage system reads the metadata and object ID Therersquos no need for asingle global namespace cache coherency or high-speed networks

Object storage products are sold by a mix of established vendors and innovative startups Products from established vendors include EMC AtmosDataDirect Networks Web Object Scaler (WOS) Dell DX Object Storage NetAppStorageGrid and Rackspace OpenStack Products from startups includeAmplidata AmpliStor Basho Riak Caringo CAStor Cleversafe SlicestorMezeo Cloud Storage and Scality Ring

ldquoObjects let you have ashared-nothing architecturewhere every node and controllermechanism doesnrsquot have toknow where every piece of dataresidesrdquo said Andrew Reichmanprincipal analyst at CambridgeMass-based Forrester ResearchldquoYou can scale bigger for cheaperAs we talk more and more aboutmassive multi-petabyte reposi-tories of data that scalabilitygets relevantrdquo

Object storagersquos characteris-ticsmdashparticularly its scalabilitylocation independence and accessibility via HTTPmdashmake it well suited for storage clouds The metadataallows administrators to apply rules that can deliver built-in multi-tenancyencryption and chargeback Amazon Simple Storage Service (S3) MicrosoftAzure and Nirvanix Cloud Storage are storage clouds based on object storage

Other uses for object storage include archiving (particularly medicalimages) and file storage that scales to multiple petabytes

The Eacutecole Polytechnique Feacutedeacuterale de Lausanne (EPFL) in Switzerland turnedto Amplidata to help digitize more than 5000 hours of video archives fromthe Montreux Jazz Festival dating to 1967 When the project began two yearsago Alexandre Delidais EPFLrsquos director of operations said he couldnrsquot find adisk storage system that met his needs and price point EPFL bought LTOtape and continued to search

Delidais said he was looking for storage that could scale to petabyteswith low energy and power consumption had faster restore times thantape and fit his budget

ldquoNothing was really available with those requirementsrdquo he said ldquoWecouldnrsquot find a disk-based technology they were all too costly or used too much energyrdquo

Delidais discovered AmplidataAmpliStor in late 2010 EPFLbought 1 PB of storage to startand will split that between twolocations and replicate Delidaissaid hersquos approximately 20through his digitization project

Of course there still arenrsquotthat many multi-petabyte stor-age implementations so objectstorage isnrsquot yet mainstream

ldquoNot a lot of buyers really need hundred-petabyte repositories nowrdquoForrester Researchrsquos Reichman said ldquoBut it seems to me the long-termoutlook will be object storage Itrsquos a better way to do file storagerdquo

MLC FLASH STORAGEThe signs are everywhere that MLC NAND flash will continue its upwardtrajectory next year and officially overtake higher-cost single-level cell(SLC) flash in enterprise systems ushering in a new era of more affordablesolid-state storage

Manufacturers have ramped up production of MLC-based solid-statedrives (SSDs) and even major storage vendors that were once hesitant to use them are joining the ranks of earlier adopters such as IBM andHewlett-Packard (HP) Co

Framingham Mass-based IDC predicts that MLC-based drives willcommand 52 of enterprise solid-state revenue next year and climb to60 in 2013

Jeff Janukowicz research director of solid-state storage at IDC saidMLC-based SSDs have reached a point where theyrsquore better able to handlethe readwrite mixes that traditional IT requires thanks to advancementsin their architectures algorithms and controllers

Online marketplace eBay Inc turned heads this year with its 100 TB deployment of Nimbus Data Systems Incrsquos S-class solid-state storagewhich uses a more industrial-strength flash variant known as enterpriseMLC (eMLC)

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

ldquoIt will be the catalyst to using LTFSrdquo he said ldquoThen you can see whatrsquoson the tape instead of depending on a database thatrsquos telling you by thetape number or barcode If you have LTFS you can search for a file thesame way you do in a file system LTFS has lots of benefits in that regardrdquo

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

therersquos a need for improving local performance mitigating extra latencyissues and adding security features

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

BACKUP ANDRECOVERY

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

therersquos a need for improving local performance mitigating extra latencyissues and adding security features

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

How our predictionsfor 2011 fared

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

GLOBAL BACKUP DEDUPLICATIONThe experts all say this is a great technology for jacking up dedupe ratios load balancingand scaling But two incorrect perceptions have slowed its adoption itrsquos only for large-scale environments and you donrsquot really need it especially if you use specific targets toback up individual applications such as Microsoft Exchange or SharePoint Donrsquot believe itWe think it will become a must-have feature as users build up their dedupe environments

MOBILE DEVICE BACKUPThis may be a technology waiting for the market to materialize Many backup apps nowhave mobile backup capabilities including CommVaultrsquos and Symantecrsquos and there arespecialized apps from the likes of Copiun and Druva along with plenty of cloud backupservices But maybe you have higher priorities right now or your users havenrsquot demandedit so yoursquore not going to sweat a few lost laptops Get a grip with millions of smartphonesand tablets finding their way into corporate data systems itrsquos not going to get any easier(see ldquoMobile backup Therersquos an app for thatrdquo)

PRIMARY STORAGE DEDUPLICATIONWe said it was hot in 2009 and again in 2010 but performance concerns and the contin-uing debate over its usefulness have stolen some of its sizzle Target deduplicationproviders have yet to embrace the technology due to concerns over performance degradation And its usefulness in primary storage is still being debated We thoughtDellrsquos acquisition of Ocarina Networks IBM grabbing Storwize and Hitachirsquos buyout ofBlueArc (with its OEM deal with Permabit) would spark interest Not yet

ldquoBIG DATArdquoHard to tell if itrsquos hot or not when we canrsquot even agree on a definition Does big datamean humongous files complex data sets or just the massive amounts of unstructureddata organizations deal with All of the above it seems and itrsquos all great fodder for thehype machine There are some real products out there and more vendors are gearing upto release products but right now itrsquos still mostly hype

BUNDLED STORAGE STACKSIt wasnrsquot hot last year and it isnrsquot hot now Why arenrsquot they more popular Follow themoney or more specifically how much it takes to get one EMC and Hewlett-Packard offer product bundles with pre-configured storage server and networking gear andsoftware NetApp gives you the directions on what to buy and how to assemble it (puttab A into slot B) Either way itrsquos going to cost you Not many companies can justify theexpense and vendor lock-in these days

STORAGE FOR VIRTUAL DESKTOP INFRASTRUCTURE (VDI)Virtual desktops promise simplified management support and security What they donrsquotpromise is enough return on investment (ROI) when you figure in storage requirementswhich can be pretty tough when yoursquore dealing with hundreds or thousands of desktopsSolid-state storage might be the answer but itrsquos a costly solution

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

How our predictionsfor 2011 fared

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

BACKUP ANDRECOVERY

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

One of the main distinctions between the different types of flash isendurance The consensus is that SLC wears out after approximately100000 erasewrite cycles eMLC at 30000 erasewrite cycles and MLC at 10000 or less But the differentials are becoming less important as the MLC drive and third-party controller vendors make improvements

ldquoThese controller manufacturers have found that they can actuallywatch the flashrsquos behavior and as long as they keep track of every singleblock and how it performs they can use certain blocks well beyond the10000 limit and up into the hundreds of thousands of usesrdquo said JimHandy founder and chief analyst at Object Analysis in Los Gatos Calif

Even the erasewrite differen-tial between eMLC and MLC isstarting to become less of anadvantage and eMLC doesnrsquot appear to be gaining the level of popularity the industry expected according to Handy

ldquoeMLC costs more than MLCand itrsquos slowerrdquo he said ldquoandsince everybody is buying SSDsfor speed a slower solution is a really tough sellrdquo

Dan Mulkiewicz IT director at Carlsbad Calif-based High Moon Studiosa division of Activision Blizzard Inc which produces popular video gamessuch as ldquoWorld of Warcraftrdquo and ldquoGuitar Herordquo said even the least expensiveMLC SSDs have performed impressively

High Moon started with 10 MLC-based SSDs nearly three years ago inworkstations and soon added another 60 or 70 after application build timesdropped from 30 or 40 minutes to four minutes

ldquoI had to come up with a cheap solution and we took a chance and it paidoffrdquo Mulkiewicz said noting that SLC flash never became a consideration

He said the failure rate on the workstationsrsquo MLC drives was less than5 and manufacturer warranties have improved from a year to three yearscomparable to that of hard drives

So Mulkiewicz had no qualms using an MLC-based cache from GridIronSystems Inc to address an IO bottleneck with his VMware server farmMulkiewicz was impressed with the dramatic performance boost Inworst-case scenarios programmers and artists once waited 70 minutesfor the code to recompile after they submitted a change With the MLC-

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

How our predictionsfor 2011 fared

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

ldquoWersquore not only comfortable with [MLC] nowrdquo Mulkiewicz said ldquowersquoredependent on itrdquo

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

ldquoIt will be the catalyst to using LTFSrdquo he said ldquoThen you can see whatrsquoson the tape instead of depending on a database thatrsquos telling you by thetape number or barcode If you have LTFS you can search for a file thesame way you do in a file system LTFS has lots of benefits in that regardrdquo

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

therersquos a need for improving local performance mitigating extra latencyissues and adding security features

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

How our predictionsfor 2011 fared

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

ldquoWersquore not only comfortable with [MLC] nowrdquo Mulkiewicz said ldquowersquoredependent on itrdquo

LTFSThe Linear Tape File System (LTFS) is expected to help usher in a tape renais-sance Itrsquos the first technology that lets users search for information on tapevia a file-tree directory making the process similar to searching disk storageUsers can drag and drop files to and from a mounted LTFS formatted tapeopening up new possibilities for incorporating tape into workflows andmaking long-term archival easier

LTO-5 the first tape format to support LTFS has media parti-tioning so a drive can write twovariable-length partitions oneach tape One partition has aself-contained hierarchical filesystem index and the secondholds the content LTFS presentsa file-structure-type interfacefor managing the files on tapeAll a user has to do is load thetape into a drive and the datacan be viewed by a browser or any application that has a tape attached to it

HP and IBM are the main developers of LTFS software and the LTFS openstandard is supported by the LTO Consortium HP supports LTFS in HPStoreOpen Automation while IBM released support for LTFS for librarieslast May with its IBM System Storage LTFS Library Edition Other companieshave delivered support for LTFS such as Crossroads with its StrongBox device and Cache-A offers LTFS capability with its flagship Pro-Cache5Power-Cache and Prime-Cache5 In addition Atempo is now fully compati-ble with the LTFS platform when using Atempo Digital Archive (ADA) a filearchiving product

LTFS is still in the early adoption phase with media and entertainmentas its sweet spot Robert Smith founder of 2PopDigitalcom which provideseditorial system support for post-production in the media and entertain-ment industry said LTFS will hit the mainstream when more archivingmanagement software supports the open standard

Randy Kerns storage strate-gist at Boulder Colo-based Eval-uator Group said the media andentertainment industry has themost immediate need for LTFSbecause of the requirement totransport data more efficientlyHe said archiving managementsoftware can be layered on topof LTFS so users can input re-tention periods and data accesscontrolsmdashthe technology will go mainstream once more archive manage-ment software supports it ldquoItrsquos really a managing archive rather than acollection of backupsrdquo he said ldquoCompanies have another alternative withtape thatrsquos more functional than just doing backupsrdquo

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

therersquos a need for improving local performance mitigating extra latencyissues and adding security features

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

CLOUD GATEWAY APPLIANCESCloud gateway appliances are garnering attention as a great way to intro-duce cloud storage into an organization These devices are easy to set upand relatively inexpensive and users can start small and scale up easily

The premise of a cloud gateway is simple the appliance installs in adata center and acts as a bridge between on-premises storage systemsand a cloud storage service The bridge is required because public cloudstorage providers rely on Internet protocols such as REST APIs over HTTPrather than conventional storage-area network (SAN) or NAS protocols By connecting on-premises storage to the cloud via a gateway the cloudstorage service can seamlessly integrate with existing systems

Although the adoption rate of cloud gateways is still relatively modesta number of products have been released in the last two years and the attention theyrsquove received along with their potential to grab market shareis what has landed them on our Hot Technologies list

ldquoTherersquos a huge interest in moving data to the cloud and I donrsquot thinktherersquos any risk tolerance for user companies to deal with cloud providerAPIsrdquo Forrester Researchrsquos Reichman said Within the cloud storage market

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

ldquoThose are some of the key attributes of cloud gateways that I think willmake them big enablers for user companies to use cloud storagerdquo he said

Cloud gateways can be integrated or combined with other products andsome vendors have already set up partnerships with backup and storagevirtualization vendors for example TwinStrata is partnering with Veeamand DataCore while StorSimple has joined forces with Microsoft The chal-lenge is that many users are unaware of cloud gateways and their benefits

REPORT CARD

How our predictionsfor 2011 fared

AUTOMATED STORAGE TIERINGYoursquod be hard-pressed to find a storage vendor that doesnrsquot offerautomated tiering so we were pretty smart on that count Butusers Thatrsquos another story as adoption is a bit slower than weanticipated

DATA REDUCTION IN PRIMARY STORAGEIBM buys Storwize Dell buys Ocarina and Permabit OEMs its technol-ogymdasha perfect storm for data reduction in primary storage right Not exactly Maybe itrsquos just the calm before the storm but itrsquos takinga long time for this technology to stir things up

VMWARE APIs FOR STORAGEVMwarersquos concession that storage vendors might be better at manag-ing their products might be the biggest story of the year Everythingabout storage for virtual machines (VMs) got easier this year fromconfiguring to backup

SCALE-OUT NASWe were probably a year early with this call There was plenty oftalk about scale-out network-attached storage (NAS) but when itcame to actual deployments not so much

MULTIPROTOCOL STORAGE ARRAYSHardly any arrays ship these days with support for just block or filethe days of those one-trick ponies are just about gone Even thoughNetApp is probably wondering what took us so long to make thisprediction wersquoll still give ourselves a pat on the back

CLOUD STORAGE SERVICESIt just seems like we hear the word ldquocloudrdquo about a thousand timesa day but the truth is that it became a real factor for enterprisedata storage this year Our surveys show nearly a quarter of you are using some kind of cloud storage service like Yogi Berra saidldquoYou could look it uprdquo

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

Some data storage managers opt to continue to rely on somewhat

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

Quantum tape libraries lead the fieldAfter finishing well but never winning in past Quality Awards surveysQuantum tape libraries romped through both the enterprise andmidrange categories this time around BY RICH CASTAGNA

Overall ratingsENTERPRISE Quantumrsquosoverall average of 655outpaced tough competi-tors in IBM (637) and Oracle Corp (634) IBMwas particularly tena-cious finishing second in three categories andthird in the other two Oracle rode one second-place finish and consis-tently strong scores to its third-place finish

In winning Quantum showed particular strength in the initial productquality and technical support categories It won the other categorieswith smaller but still convincing margins Coming in second this timeIBM maintained its record of always finishing in the top three since the inception of the enterprise tape library Quality Award surveys

MIDRANGE Quantumbested an even largerfield of competitors in the midrange group andwon by an even largermarginmdash686 to 652mdashover IBM As it did in theenterprise group IBM displayed remarkableconsistency adding thissecond-place finish to its four seconds and onethird in previous surveysOracle placed third with a642 that just trailed IBMBut Quantumrsquos mastery of the midrange was clear with across-the-boardcategory wins in the five rating categories and the only above-700 cate-gory ratings for product features (706) and initial product quality (703) Ina near replay of the enterprise contest IBM came in second in four of thefive categories ceding the second spot to Oracle for initial product quality

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

ldquoI think cloud gateways will find a home eventually as users get morecomfortable with cloud storage technology I see them getting more em-bedded and leveraged as cloud storage appliancesrdquo said Terri McClure asenior analyst at Milford Mass-based Enterprise Strategy Group (ESG)

Some industry experts expect data storage vendors will build this tech-nology into their arrays if the concept catches on That would make it easyfor onsite storage systems to treat a cloud storage service as simply anotherstorage tier without having to take an intermediate step

ldquoI think the jury is still out as to whether this should be a fully separateproduct and a fully separate vendor or if what wersquore really talking about isa feature of other productsrdquo Forrester Researchrsquos Reichman said

Another factor that has slowed acceptance of gateways is that the vendorsoffering these products are mostly startups

ldquoItrsquos going to take some market education and probably some effectivepartnering on the part of those smaller vendors to really get their productto be considered by buyersrdquo Reichman noted

Taylor Higley director of information services at the American Federationof Government Employees (AFGE) recently deployed TwinStratarsquos Cloud-Array cloud gateway When asked why he chose a TwinStrata gateway hisanswer was simple

ldquoReally it was the ability to leverage cheap Amazon S3 storage but stillhave the security and reliability of Veeamrsquos Backup amp Replication systemrdquohe said ldquoTwinStrata was the missing piece to make it all workrdquo

VIRTUAL STORAGE APPLIANCESWith server virtualization firmly entrenched in data centers server-basedshared storage is making a significant mark in the form of virtual storageappliances (VSAs) These software-based systems enable the advancedcapabilities of server virtualization without expensive dedicated storagehardware They run inside a virtual machine (VM) and create shared storagefrom the storage attached to the physical server a VM runs on In 2012 weexpect to see more companiesmdashespecially small- and medium-sized busi-nesses (SMBs)mdashturning to server-based storage as an inexpensive way tosupport server virtualization

Virtual storage appliancesmdashsuch as HPrsquos StorageWorks P4000 VSA Soft-ware and DataCorersquos SANsymphonymdashhave been on the market for a numberof years but VMware Incrsquos rollout of its vSphere Storage Appliance is ex-pected to inject more interest into this tech vSphere Storage Appliance

which is targeted specifically at SMBs runs across multiple hypervisors aggregating direct-attached storage (DAS) into pooled storage

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

Barrenrsquos IT department makes use of DataCorersquos high-availability mirroringcapabilities resulting in 10 TB of usable storage in high-availability mode

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

ldquoWersquore going to see incredible evolution happen inside the virtual infra-structure by vendors like VMwarerdquo said Jeff Boles senior analyst anddirector of validation services at Hopkinton Mass-based Taneja GroupldquoAnd the virtual storage appliance technology coming out for VMware [is] just one more very innovative technology from one of the hypervisorvendors and storage vendors better be reading between the linesrdquo

Others see VMware as leveraging its skill set in virtualization to broadenits technologyrsquos appeal to morecompanies ldquoI think that VMwaresees storage as a stumblingblock keeping people from ex-panding their server virtualiza-tion capabilities and to someextent [VMware] has decided totake it in their own hands to tryand fix itrdquo said George Crumpfounder and lead analyst at Storage Switzerland

Virtual storage appliances make more sense for SMBs because theyrsquorebased on iSCSI rather than Fibre Channel (FC)

ldquoYou donrsquot find a whole lot of traditional businesses traditional enterprisesdeploying VSAsrdquo Taneja Grouprsquos Boles said ldquoIf theyrsquore traditional enterprises[and] theyrsquore doing some private cloud or public cloud stuff you might findthem deploying [virtual storage appliances] thererdquo

One vendor with a big footprint in the virtual storage appliance market isDataCore with its SANsymphony-V software which virtualizes storage acrosspools of heterogeneous systems turning commodity servers into SANs

Barren County Schools in Glasgow Ky turned to SANsymphony-V after aserver consolidation project The IT department had consolidated 30 physicalservers to four running 30 VMware VMs It then replaced EMC SANs with twoDell servers running DataCore software

ldquo[The EMC system] didnrsquot have the processes the caching to do some ofthese more advanced features so [the key] in looking at SANsymphony wasthe fact that they didnrsquot care what hardware [was used]rdquo said Cary Goodedistrict technology service specialist at the Barren County Technology Office

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

ldquoTheyrsquore trying to promote thiswhole style of data protection to customers who donrsquot have a second site where they mightreplicate data tordquo said LaurenWhitehouse a senior analyst at ESG

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

INTEGRATED CLOUD BACKUPCloud backup has been around as a consumer service for years and itmakes a good deal of sensemdashkeeping an offsite copy of data is prettymuch disaster recovery 101 However in the enterprise space a number of roadblocks have hindered widespread cloud backup adoption One ofthe biggest issues limiting its acceptance was that it required an entirelynew backup approach and a cloud-specific backup application But thatrsquoschanging and a number of major backup software vendors now allowusers to back up directly to the cloud

CommVault Systems Incrsquos Simpana lets you back up to any cloud vendorthat supports the REST protocol such as Amazon Microsoft Azure Nirvanixor Rackspace Symantec Corprsquos Backup Exec can back up to Symantecrsquoscloud while the firmrsquos NetBackup has an option to back up to NirvanixEMC NetWorker can ship backup data to EMC Atmos-based cloud storageservices

Cloud integration with tradi-tional backup products allowsusers to create onsite disk back-ups for fast restores but ratherthan sending copies offsite ontape they can now easily choosethe cloud as an alternative for disaster recovery In the event a largeamount of data must be restored from the cloud many services can shipdata on an appliance or disk to a customer site Other users might see it asan archiving tier sending older data to the cloud for long-term retention

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

In winning Quantum showed particular strength in the initial productquality and technical support categories It won the other categorieswith smaller but still convincing margins Coming in second this timeIBM maintained its record of always finishing in the top three since the inception of the enterprise tape library Quality Award surveys

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

IRST A LITTLE MATH Consider an organization with 5000 employees 20 of whom areknowledge-based workers with a reason to have corporate data on their mobiledevices Then assume that each worker is carrying 20 GB of corporate data ontheir devices With a simple calculation we can determine that this hypotheticalorganization has 20 TB of potentially unprotected data stored on mobile devices

No organization would stand for a 20 TB hole in its data protection strategyinside its data center yet such holes are routinely ignored outside the data centerIronically the data floating around outside the data center is at even greaterrisk for loss Itrsquos easy to see how quickly small amounts of data across largenumbers of devices can add up to a significant problem

MOBILE BACKUPTherersquos an app for that

Users may be carrying a significant amount oftheir companyrsquos intellectual property on theirsmartphones tablets and other ultraportabledevicesmdashand that data needs to be protected

BY PHIL GOODWIN

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

WHATrsquoS A MOBILE DEVICETo start addressing the issue of data protection for mobile devices letrsquos determine exactly what devices should be included under that term LaptopPCs would represent the most significant repository of mobile data and toooften theyrsquore overlooked as containersof valuable corporate data Rapidlygaining ground as data repositoriesare tablets and sophisticated smart-phones which wersquoll refer to as ldquoultra-portable devicesrdquo These devices haveinternal flash storage typically rangingfrom 8 GB to 64 GB and many have secure digital (SD) card expansionslots providing significantly more storage capacity And you can expectthe capacities of these ultraportabledevices will continue to expand dramatically

Organizations must recognize thepotential risk these devices representMost have well-defined policies thatprohibit the use of corporate devices for personal tasks But this line isroutinely crossed whether the nonconforming activity involves personalemail calls text messages or document creation or editing

Ultraportable devices make enforcing the line between personal andbusiness use even more difficult Users are increasingly employing personaldevices theyrsquove purchased themselves for business-related activities andpersonal tasks Examples include iPhones BlackBerrys and Android-basedsmartphones that people use to connect to their business email accountsiPads and other tablets may also be used to view send and receive businessemail using Web browsers and may be used to edit and store documentsSales reps may be able to download price lists proposal materials and othersales documentation using any Web-enabled device Itrsquos becoming increas-ingly impossible and impractical to prohibit the mingling of personal andbusiness use of ultraportable devices In many cases itrsquos a companyrsquos exec-utives driving the move to allow tablets to access corporate resources Andif itrsquos OK for the boss others wonrsquot be far behind

Itrsquos not unusual for a knowledge-based worker to have a laptop tabletand a smartphone Thus in our earlier fictitious company example 1000

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

knowledge workers might be toting around as many as 3000 devices allwith corporate data stored on them To deploy a backup solution for thisscenario you must address a high volume of devices with low volumes ofdata per device Bandwidth is rarely a problem but deployment standardi-zation support and updates make it a challenge

The deployment of ultraportable devices is growing exponentially so thequestion is how can IT managers get out in front and address the issueproactively The good news is that it may be easier than you might thinkThe bad news is that it may be more complicated than some think it will beLetrsquos dissect the issues and see why this is a good newsbad news issue

YOUR POLICIES MAY NOT BE ENOUGHAlthough organizations generally have clear policies regarding the separationof private and business use of devices they rarely specify data protectionrequirements or procedures Mobile device backup often falls between thecracks Backup is the domain of the data storage organization but PCs arethe domain of the end-user computing group and cell phones are typicallywithin the domain of the telephony or telecomm group Tablets havenrsquot founda place in most companies yet so they may just be the domain of the userSo the physical asset is managed by one group and the process by anotherneither group assumes ownership Hence the first step in establishing apolicy is determining who owns the whole operation In practice it will require the coordination of all groups

1 Leverage the PC as the central backup platform

2 Establish a laptop backup strategy

3 Worry about corporate data only not the entire ultraportable device

4 Standardize the products yoursquoll support one-offs are on their own

5 Consider a specialized cloud provider to take over the whole thing

How to get a handle on ultraportable backup

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

Quantum tape libraries lead the fieldAfter finishing well but never winning in past Quality Awards surveysQuantum tape libraries romped through both the enterprise andmidrange categories this time around BY RICH CASTAGNA

Overall ratingsENTERPRISE Quantumrsquosoverall average of 655outpaced tough competi-tors in IBM (637) and Oracle Corp (634) IBMwas particularly tena-cious finishing second in three categories andthird in the other two Oracle rode one second-place finish and consis-tently strong scores to its third-place finish

In winning Quantum showed particular strength in the initial productquality and technical support categories It won the other categorieswith smaller but still convincing margins Coming in second this timeIBM maintained its record of always finishing in the top three since the inception of the enterprise tape library Quality Award surveys

MIDRANGE Quantumbested an even largerfield of competitors in the midrange group andwon by an even largermarginmdash686 to 652mdashover IBM As it did in theenterprise group IBM displayed remarkableconsistency adding thissecond-place finish to its four seconds and onethird in previous surveysOracle placed third with a642 that just trailed IBMBut Quantumrsquos mastery of the midrange was clear with across-the-boardcategory wins in the five rating categories and the only above-700 cate-gory ratings for product features (706) and initial product quality (703) Ina near replay of the enterprise contest IBM came in second in four of thefive categories ceding the second spot to Oracle for initial product quality

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

This cross-functional complication is an excellent reason to consider out-sourcing the whole thing to a cloud backup provider Third-party providerswill manage the whole process including deployment management andtechnical support There may be cases however due to security compli-ance (or corporate governance) or ITrsquos reluctance to use third-party servicesthat make outsourcing an unattractive alternative In those situations ITmust instigate the data protection policy based on business requirements

Backup policies are ordinarily driven by recovery time objectives (RTOs)and recovery point objectives (RPOs) Mobile backup is a bit different andneednrsquot be as complicated RPO may not be easy to establish as it may bedriven by network connectivity a daily backup schedule or product optionsThe variables of ultraportable device availability make backup timing lesscertain than an always-on storage array in the data center Informationchanges on individual devices arenrsquot as volatile as data center devicesTherefore recovery certainty is moreimportant than backup timing More-over a 24-hour RPO is probably a vastimprovement over the intermittent ornon-existent data protection usershave today

The essence of a mobile backuppolicy is pretty simple who whatwhen and how The ldquowhordquo can be theuser (ie user-initiated backups) or systemsoftware control (ie pre-scheduledand automatically launched) The ldquowhatrdquo is the device the ldquowhenrdquo the back-up event and the ldquohowrdquo the backup utility Thatrsquos about as complicated as itneeds to get for typical applications and users

PCs THE CENTER OF THE MOBILE UNIVERSETo get a handle on ultraportable devices the first thing to do is to designatethe PC as the center of the mobile universe Some might argue that tabletsare quickly supplanting PCs as a primary device This may be true for certaintasks such as Web surfing video conferencing and even document lookupbut tablets still have a long way to go for effective document spreadsheetor presentation creation Tablets may be great display devices but PCs remainthe go-to platform for document creation (This article is being written on aPC while an adjacent iPad plays tunes) Nobody does any serious documentcreation on a smartphone and the inherent form factor of those devices

The essence of amobile backup policyis pretty simplewho what whenand how

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

makes it forever unlikely The larger size of tablets may allow them to evolveto supplant PC functionality but for the foreseeable future consider PCsthe hub of the mobile world

From an ultraportable perspective PCs play a key role as the centralrepository for syncing data with multiple devices This will most often in-clude calendars contacts email and the like Yes this data can and often issynced to external servers However BlackBerrys may be synced to a Black-Berry server Exchange to an Exchange server and so on By using the PC asa central syncing device the user has one central location to recover dataon a self-service basis The added inherent remote sync gives the best ofboth worlds with user self-service and protection from data loss Moreoverif one service experiences an outage users have a ldquohigh-availabilityrdquo solu-tion from other devices Not bad for whatrsquos essentially a no-cost solution

Placing the PC in this key role expos-es the vulnerability of most PC backupstrategies or more accurately the lackof a strategy Even though theyrsquore wellunderstood theyrsquore not necessarilywell protected Organizations that donrsquot have an automated laptop backupsolution must seriously consider oneConvenient in-house solutions areavailable from most name-brand backup vendors including CommVault EMCand Symantec and specialized vendors such as Copiun and Druva Remotelaptop backup is also a perfect application for the cloud as provided by well-known vendors such as Asigra Barracuda Networks Carbonite Mozy (EMC)and Norton (Symantec) Cloud-based solutions provide consistent policiesacross the organization while minimizing the impact on the IT organization

By using the PC as the central syncing platform it becomes the backupserver for the ultraportable devices In most cases the sync process is automatic In this architecture backing up tablets and smartphones takesless effort to protect corporate soft assets than one might think

DEVICE-SPECIFIC ULTRAPORTABLE BACKUPEven though a PC-centric approach will protect the majority of corporatedata the plethora of applications for smartphones and tablets ensures thatat least some users will continually push the devices into uses that no onecould reasonably anticipate Consequently IT organizations shouldnrsquot over-

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

look the need to back up the devices in addition to syncing themLetrsquos start with the easy part of backing up smartphones and tablets

For those devices that use an SD card or other such storage format userscan remove the card and copy it to a PC Of course this requires user disci-pline to do so on a periodic basis Period reminders from the help desk maybe enough to foster the desired behavior

The first thing one will notice when considering ultraportable backup is the fragmented nature of the task Pictures videos and music may bebacked up to iTunes Google Picasa or a PC Application backup may go to Titanium Backup (Android) or the Apple iStore When looking into thespecifics of these backup applications one finds that they tend to be veryuse-case specific Some may back up the Android home screen for examplewhile others sync contact and calendar information and still others backup files Users who are serious about data protection may be forced touse a suite of applications

This fragmentation obviouslymakes backup of ultraportable devicesmore complicated Even so it can bebeneficial because IT organizationscan tailor solution specifications forcorporate data only User data suchas pictures music and videos shouldrightly be the responsibility of theuser However a corporate decision to deploy a particular encryption prod-uct may interfere with user data if itencrypts the entire device This may lead users to disable the product thusdefeating the efforts of the IT department

The next thing one will notice when searching for ultraportable backupis a shortage of name-brand solutions Given the tens of millions of ultra-portable devices sold it would seem to have significant market potentialSymantec offers a beta version of Norton Connect for iPadiPhone backupin the Apple App Store The app itself is free but it requires a Norton OnlineBackup subscription Of the other 32 applications for ldquodata backuprdquo in theApp Store all are boutique-type solutions that donrsquot appear to be gearedtoward enterprise deployment

As IT organizations decide how to cope with corporate data on ultra-portable devices there are many factors to weigh The first is how tocope with very large device populations unpredictable connectivity and

highly individualized environments Despite these difficulties best-practiceorganizations will address the need to protect corporate assets Cloud-based solutions offer the advantages of offloading the deployment man-agement and support to specialists Cloud providers will also be preparedto address the needs of enterprises

For organizations that prefer to architect and manage their own solutionthey must first decide which part of the IT organization will own and man-age the solution In deciding what tools to use theyrsquoll find that ultramobilebackup becomes a stack of its own By focusing on what data is valuableto the organization much of the peripheral personal data can be ignoredThe task is to reduce the number of variables to those that count and thusmake enterprise deployment a manageable process 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

Quantum tape libraries lead the fieldAfter finishing well but never winning in past Quality Awards surveysQuantum tape libraries romped through both the enterprise andmidrange categories this time around BY RICH CASTAGNA

Overall ratingsENTERPRISE Quantumrsquosoverall average of 655outpaced tough competi-tors in IBM (637) and Oracle Corp (634) IBMwas particularly tena-cious finishing second in three categories andthird in the other two Oracle rode one second-place finish and consis-tently strong scores to its third-place finish

In winning Quantum showed particular strength in the initial productquality and technical support categories It won the other categorieswith smaller but still convincing margins Coming in second this timeIBM maintained its record of always finishing in the top three since the inception of the enterprise tape library Quality Award surveys

MIDRANGE Quantumbested an even largerfield of competitors in the midrange group andwon by an even largermarginmdash686 to 652mdashover IBM As it did in theenterprise group IBM displayed remarkableconsistency adding thissecond-place finish to its four seconds and onethird in previous surveysOracle placed third with a642 that just trailed IBMBut Quantumrsquos mastery of the midrange was clear with across-the-boardcategory wins in the five rating categories and the only above-700 cate-gory ratings for product features (706) and initial product quality (703) Ina near replay of the enterprise contest IBM came in second in four of thefive categories ceding the second spot to Oracle for initial product quality

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

QUANTUM CORP one of the brand names that helps define the tapelibrary category has finished among the top three in three of ourprevious five Quality Awards surveys for enterprise tape libraries In the sixth edition of the service and reliability ratings it breaks

through with an impressive overall win highlighted by a clean sweepof the five rating categories If that wasnrsquot sweet enough Quantum alsotopped the charts among midrange tape libraries equaling its enterprisefeat of five category wins and romping to victory

Thatrsquos not to suggest the other product lines represented in the surveywere slouchesmdashthe average of the overall scores for enterprise productswas second to only the last Quality Awards survey and the midrangegrouprsquos overall average missed a record by a mere 004 points

Tape might be playing a diminished or modified role in a lot of storageshops but based on the consistently high ratings this category receiveswe can only conclude the products are more fully featured easier to useand more reliable than ever

In winning Quantum showed particular strength in the initial productquality and technical support categories It won the other categorieswith smaller but still convincing margins Coming in second this timeIBM maintained its record of always finishing in the top three since the inception of the enterprise tape library Quality Award surveys

BREAKING DOWN THE NUMBERS

bull Oraclersquos two statement winners were a 623 for having knowledgeable third-party partners and a 626 for providing adequate training

bull No support surprises for tape users The higheststatement average for all vendors was a 643 for ldquoVendor supplies support as contractually specifiedrdquo

bull Overall there was only one sub-600 statementscore which suggests vendors are doing a prettygood job of supporting their products

Midrange tape librariesTECHNICAL SUPPORT

BREAKING DOWN THE NUMBERS

bull The top four vendors (Quantum IBM Dell and Oracle)all scored above 600 on all eight statements

bull Vendors may want to revisit their training practicesas the statement with the lowest average score (590)was for providing adequate training

bull As with their enterprise cousins the top supportgrade for all midrange tape libraries was 635 for thevendors delivering support as promised

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

Itrsquos not really a new idea rather wersquore just now starting to see solutionsthat attempt to bring together capabilities that used to come from manyseparate storage products In part itrsquos also a reaction to changing IT prac-

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

The replicationengines bandwidthconsumption andduplicate storageinfrastructurerequired for disasterprotection can easilyinduce some serioussticker shock

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose

A number of vendors try to communicate this message in terms ofstorage efficiency But storage efficiency often implies a sort of softqualitative comparison and it can fool users into thinking that improvingstorage might just be about tweaking one or two of the most obvious dimensions of efficiency such as capacity optimization Whether we callit storage density or storage efficiency itrsquos more than a single dimension

Wersquove explored various examples of this functional convergence creatinggreater storage density in recent lab exercises I see those exercises asrepresenting the market as a whole each vendor in this consolidatingscaling-storage landscape is striving to enhance the value and competi-tiveness of their offerings But the real winners are users who are finallygetting storage technologies that can help enterprises scale their storageinfrastructures through better storage density rather than sprawl 2

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

EPLICATION TECHNOLOGY a staple of traditional disaster recovery (DR) strate-gies can also play a pivotal role in local data recovery processes Replica-tion isnrsquot new but itrsquos being used in new ways especially with the increasedpopularity of virtualization and cloud services models (These technologiesoften reduce the need to maintain on-premises physical system replicas)Optimization technologies such asdata deduplication and compressionhave also given replication technologya boost because they enable more efficient data transfers across local-area networks (LANs) wide-area networks (WANs) or storage-area networks (SANs)

But the larger contributors to repli-cationrsquos shift from DR standard to op-erational recovery tool are data growth and diminishing downtime toleranceAnnual data growthmdashaveraging 10 to 30 for most companies but ashigh as 40 or more for larger companies (those with more than 100 production servers1)mdashis wreaking havoc on ITrsquos ability to copy systems and data for recovery purposes and meet recovery time objectives (RTOs)

Companies of all sizes also report limited leniency for the span of timethey can do without access to applications and data For tier 1 data surveysby Enterprise Storage Group (ESG) reveal that for nearly three-quarters ofrespondents this amount of time is three hours or less For a little morethan 50 of those surveyed itrsquos one hour or less For many meeting aservice-level agreement (SLA) for this RTO would be a daunting task withtraditional backup approaches

REPLICATION TECHNOLOGY OVERVIEWReplication refers to technology solutions that create a mirror copy ofdata It can be performed on different infrastructure components includingthe host system and storage array or in the network Host-based replicationasynchronously replicates data regardless of storage array make or modelArray-based replication software runs on one or more storage controllersresident in disk storage systems synchronously or asynchronously repli-cating data at the logical unit number (LUN) or volume block level betweensimilar storage array models

Network-based replication per-forms like array-based replication buthas the advantages of running on anetwork-resident appliance or intelli-gent switch and supporting dissimilarstorage systems Therersquos also applica-tion- or database-specific replicationtypically packaged with or an add-onto the application Application-basedreplication copies a specific apprsquosdata to another instance of the application taking advantage of its intimate knowledge about that app to offer optimal performance and application integrity

Replication solutions can be broken into two main categories synchronous and asynchronous With a synchronous solution data iscopied to the replica (target) as soon as itrsquos written to primary storage(source) with the write to primary storage being acknowledged after thetarget storage array confirms the data was written to the replica In con-trast asynchronous replication acknowledges the write and then movesdata to the target replica introducing a lag in the synchronicity of systems

The differences between these approaches can be divided into threecategories bandwidth requirements latency limitations and the potentialimpact on applications Synchronous replication typically requires morebandwidth and latency limits it to a campus distance An asynchronousapproach is better for over-distance replication because latency isnrsquot afactor and low-bandwidth connections are better tolerated As its namesuggests a synchronous approach ensures that data on source and target

Network-basedreplication performslike array-basedreplication but has the advantagesof running on a network-residentappliance or intelli-gent switch and supporting dissimilarstorage systems

systems are in lock step But since the write acknowledgment is delayeduntil the data has been replicated any time delay could impact the per-formance of the application Asynchronous replication is far less likely toaffect primary application performance However asynchronous replicationcould get out of synchmdashso much so that it jeopardizes the ability to meetrecovery point objectives (RPOs)

REPLICATION RISKS REWARDSSome might consider replication a risky approach to satisfy backup require-ments Why Therersquos no way to roll back to a previous point in time Ifcorrupted data is replicated then the replica is damaged goods Thatrsquoswhy implementing snapshot or continuous data protection (CDP) technologywith replication may make more sense

Implementing a snapshot or CDP strategy locally for operational recoveryand asynchronously replicating the point-in-time copy to a remote loca-tion for disaster recovery would provide the failsafe measures to makereplication a more viable and reliable method of data protection This approach can also be more optimized since only the changed blocks between point-in-time captures are replicated Furthermore at either the source or target location recovery can occur to any previous point in time potentially improving RPOs

Replication has seen an uptick in adoption since ESG polled 400 IT pro-fessionals in North America regarding their organizationrsquos current andplanned data protection strategies and technologies In ESGrsquos 2008 survey30 of respondents cited replication use vs 46 today Similarly those respondents stating an expectation to deploy replication sometime in thenext two years is currently 37 compared to the 30 intending to deploy inthe 2008 study As pressure mounts to capture and more importantly re-cover ever-growing volumes of data within increasingly limited windows oftime replication for operational recovery should get serious consideration 2

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

58 STORAGE December 2011

iF YOUR JOB involves storing data you already know storage eats up budgetdollars faster than just about anything else in IT But as daily practitionerswe rarely notice just how many bucks storage is truly consuming The mar-keting hype for data storage products stays focused on magic bullets likeldquomore capacity per dollarrdquo or ldquomore IO per dollarrdquo but the cost of storageis about more than that

One of the best ways to considerthe true cost of storage is to thinkabout whatrsquos required to store a single piece of data over its entirelifetime This is called the ldquolifecyclecost of data storagerdquo and it includesthe technologies processes andworkflows across all types of stor-age This type of bottom-up look atstoring a piece of data over a periodof time not only helps us understandwhat data storage truly costs buthelps us determine what we shouldbe looking for when wersquore shoppingfor data storage products

The classic challenge for the strategic storage manager is that the vastmajority of data created in the data center starts its life on primary storageso storage purchasers tend to fixate on these costs But capital costs areactually more of a distraction than a real representation of what storagecosts Even worse the costs are even more skewed when you consider thedissimilar products that are typically part of most storage environmentsEven the total costs of primary data storage are often misunderstood Pri-mary storage is often poorly provisioned and underutilized a problem thatrsquoscompounded as more storage systems are added and more features are

Determining the real cost of storageVendors tout dollars per gigabyte per IO

but figuring out what a data storage system will really cost your company is a much more complicated process

The classic challengefor the strategic storage manager isthat the vast majorityof data created in thedata center starts its life on primarystorage so storagepurchasers tend tofixate on these costs

licensed (you may need additional replication or copy functionality withmultiple systems installed) And yoursquore bound to see at least a linear in-crease in the time and effort required to manage the storage especiallywhen time-consuming tasks like data migrations are required

But the cost of storing data goes beyond just primary storage Each pieceof stored data is surrounded by an ecosystem of information services Dataprotection is the most obvious and it typically consists of several partssuch as the management of multiple disk and tape tiers and the logisticsof getting protected data offsite A holistic look at the cost of data protec-tion alone is likely to dwarf the capital costs of primary storage systems

There are plenty of other costs besides data protection Regulatory com-pliance and the changing nature ofintellectual property encourage ever-longer retention of data To hold ontomore data for longer periods of timecompanies must spin up entire infra-structures and establish practicesaround information archiving searchand retrieval Disaster recovery is yetanother data protection function thatcanrsquot be ignored and its cost can besignificant The replication enginesbandwidth consumption and dupli-cate storage infrastructure requiredfor disaster protection can easily induce some serious sticker shock

Taneja Group has done extensive benchmark testing of hypervisors forwhat we refer to as virtual machine (VM) density itrsquos based on the idea that different hypervisors are more or less efficient so that given matchinghardware some will be able to run more VMs or deliver better performanceWhen considering all the hardware licensing management effort and con-sumption of data center resources this can have an enormous bottom-lineimpact Recently wersquove also focused on ldquostorage densityrdquo which is a similarconcept It considers how a product or technology can help you shrink yourdata footprint when considered across storage capacity storage systemsbandwidth consumption and human interaction

tices in the enterprise with virtualization becoming mainstream data protection practices have had to change and itrsquos not uncommon to see primary storage products that incorporate some aspect of data protectionSimilarly data storage products are featuring better optimization and secondary storage systems are raising performance and becoming moregeneral purpose
