Server Virtualization: SuccessVDI: Not So Much…
Why?
So why has server virtualizationbeen so successful?
Server virtualization is a clear win!
Server virtualization is easy!CAPEX savings is EASY to showSavings are HUGE!Already in the datacenter – it’s a form factor change!Standardization is a GOOD THING!OPEX is simply a nice byproductLet’s face it – a P2V is a simple migration process
So why is VDI ‘on hold’ in so many organizations?
VDI is not so easy!
StorageHost Servers
Image Management
Brokers
ProtocolsDisk IO issues
Personalization
Loss of Control
VDI ROI isn’t as clear CAPEX is tough to showOPEX is pretty much the only savings availableDesktops have to be “moved”Users don’t like “standardization”Let’s face it, there isn’t an “easy” migration process to
virtual desktopsA number of “secondary” products are needed
So what are the key issues inVDI projects?
It’s really not about the brokers anymore
Fast protocol PCoIP
Non-persistent desktop provisioning & storage reduction Composer/Linked Clones
Basic profile mgmt. RTO asset acquisition
Fast protocol ICA/HDX
Non-persistent desktop provisioning & storage reduction Provisioning Server
Basic profile mgmt. Sepago asset acquisition

It’s about the tradeoffs (pick 2, or maybe 1)
VDI SuccessTriangle
Key issues in more detailSingle image management comes with a pricePersonalization means loss of single image
managementPersonalized desktops increase storage costs
(footprint)VDI itself has higher IO requirements than servers!All of this on top of user acceptance issuesNo good offline tools todayBrokers don’t always scale to the thousands very well
Do you have a desktopvirtualization strategy?
Start with your current desktop strategy
The Personalization Challenge
What you see: What users see:
The Storage ChallengeCapacity footprint can be reduced via numerous technologies
IO… not so muchDesktop IOPS rules of thumb?
Low: 3-4 Med: 6-12 Heavy:16-20
What is all this RAID penalty stuff?Must design to handle the IO load
The Management ChallengeGenerally there are big trade-offs
Aim for single image management and you lose “persistent” desktops that sustain user persona
Use persistent desktops and you lose single image management (and move right back to traditional,higher OpEx desktop management)
Single image management reduces storage footprint(linked clones, PVS) but at the cost of personalization
Do existing management tools fit the VDI world or your use case?
So what should I be on thelook out for?
Common mistakes in VDIDesigning the hardware first
Too many variables to choose hardware out of the gate Just duplicating server virtualization hardware won’t work
Believing everything the vendors say “The vendor said I could easily virtualize all of my apps.” “The vendor said I could get 120 desktops per host.”
Not configuring the disk subsystem properlyForgetting about “personalization” of the desktop
Key “check boxes” for your designDefine what you are delivering and for whomEnsure your design covers the following:
Base OS delivery and updating Application delivery and updating (even the complex apps) Personalization (including user-installed apps) Broker configuration and requirements Non-persistent vs. persistent desktop use cases Storage configuration (capacity footprint AND IO load) WAN, LAN, and offline use cases
Hardware recommendationsSmaller servers with more coresGood storage controllersMore memoryNEW: solid state drive (SSD)
Hybrid arrays combine SSD and SAS in single array with intelligent data placement to solve IOPS and capacity problems
NEW: zero clients Less energy & fewer breakable parts vs. thin clients
Build redundancy through quantity
Software recommendations
NEW: desktop layering solutions Eliminate “pick 1 or
2” tradeoffs Combine single
image patching, easy app delivery, full user personalization, and storage savings in one solution
VDI @ WycheTom Crowe, IT Manager
Wyche Background
About Wyche• 2 Offices in South Carolina• 32 Attorneys• 32 Staff• Transactional and Litigation Practices
Wyche IT• IT Manager(me)• 1 Help Desk• 1 Litigation Support
VDI Motivation
• Looming PC lease return deadline• Decrease rollout cycle for new machines
• New users• New/Updated software
• Potentially move away from 3 year refresh cycle• Replace ancient remote access solution• Green initiative within firm
VDI Concerns
• In mid 2009, still new in the market• Total cost of ownership• How to handle mobile attorneys• Desktop performance• All “eggs” in a single basket
Technology
• Shared with virtual servers– Cisco 3750G switches– HP Lefthand P4500 iSCSI SAN– vSphere 4 Advanced
• Pano Logic Zero-Client usingPano Broker– No OS on the hardware
• Unidesk VDI Provisioning and Management – OS and App deployment and User personalization
Technology
Servers• HP Proliant DL360 G6
– 2 x Xeon E5504 @ 2 Ghz (8 cores total)
– 36 GB memory– 2 x 72 GB SAS for boot and
logging– 6 x 1 Gb NIC ports
• HP Lefthand P4500 SAN– 2 nodes– 12 x 450 GB SAS per node– 2 x 1 GB NICs
Desktop VMs• Windows XP SP3• 1 GB memory• 30 GB “hard drive” thin • 8 GB user data
Consolidation of ~25 desktops per vSphere host
• Zero-client with no OS on the hardware– No local desktop support concerns– Small desktop footprint: 3.5” x 3.5” x 2.0”– Low power usage: 6.5W max, < 0.2W sleep
• Pano Broker– Included with Pano device purchase– Simple management interface– Integrates seamlessly with vSphere
• Pano Remote Access– Windows 2008 Terminal Services Gateway– Pano USB dongle is simple to use
• OS, Application, and User State virtualization– Desktop is composed at boot with all required apps and OS layers– Persistence of user persona regardless of desktop– Single-image management for OS and Apps, reduced SAN storage– Security updates applied to primary OS or App layer pushed out
immediately or on schedule; guarantees all updates are applied
Unidesk
• Application layers make it easy to deliver any app• Packaging requires only a normal installation (Setup),
then assign the layer to 1 or more desktops
Testing and Rollout
• Pilot group was pivotal - ~2 months• Rollout to groups, do not convert an entire practice area at a
time. ~ 1 month to deliver to all users• Monitor host performance closely
– performance with 25 VMs is different than 5.• Be aware of specific apps and how they impact a host.
– Anti-virus adds 3-5% to idle CPU of VM, x25 VMs can be a problem.
VDI Reality… 18 months later
• User feedback is important• Easy to improve performance for users• All devices are now more tightly connected
• Visibility into the user experience is difficult without additional tools• Peripherals are difficult
• Saved money over traditional desktops? Not yet but getting there• Would I do it again? YES!
