SAN considerations for the Virtualized Data Center
Tim Gwinn
Solutions ArchitectLeftHand Networks, an HP company617-678-6716Tim.Gwinn@hp.com
A brief background• Technology leader
−Founded in 1999 as LeftHand Networks−More than 12,000 installations−Over 3,500 production iSCSI SAN customers−Ranked as “Visionary” in Gartner’s Magic Quadrant 2008 and 2009
• All inclusive feature-set −“Pay-as-you-grow” architecture−Cost-effective high availability−Scalable performance −Simplified management for virtual environments

Outstanding TCO
• FC & iSCSI host ports• FC & FATA HDD• Storage
consolidation + disaster recovery
• Simplification through virtualization
• Windows, HP-UX, Linux, VMware, Citrix, Hyper-V, MAC OS, and More
Always-on availability
• Data center consolidation + disaster recovery
• Large-scale Oracle/SAP applications
• HP-UX, Windows, + 20 more, including NonStop & mainframe
Low cost consolidation
• 4GB FC, 1GbE iSCSI, and 3Gb SAS
• SAS & SATA together• Controller-based

for virtualization• VMware, Citrix,
Hyper-V, Windows, Linux, and More
Cost
• All relevant features should be included. No surprises.
Performance
• Must support dynamic workloads concurrently
Scalability• Scale capacity and performance linearly• No forklift upgrades or disruption
Availability• High availability to keep data online during unplanned events. No SPOF.• Disaster recovery to recover data after unplanned downtime occurs.
Manageability
• Simple to administer
Storage requirements
Cost
• All inclusive software feature-set
Performance
• Storage clustering, 10 Gig support, and storage tiering
Scalability
• Buy only what you need today, scale capacity and performance linearly online
Availability• Highly available by default. Multisite SAN support• Disaster recovery included.
Manageability
• Simple to install and administer
LeftHand SAN Advantage
•Scalable performance and capacityStorage Clustering
•Beyond the box availabilityNetwork RAID
•Reduce costs, increase capacity utilizationThin Provisioning

5 features with every LeftHand SAN
SAN/iQ Storage ClusteringTrue clustering brings reliability, performance, and ease of management
•Storage clustering− Aggregates critical components− Data is load balanced− Predictable scalability
•Grow on your terms− Scale-out storage− Non-disruptive− Throttle bandwidth
•Storage tiering− Optimized for type of data− Online volume migration
•Simple centralized management− One step server-volume mapping− Integrated performance management

SAN/iQ Network RAIDAlways on storage, data remains accessible during site failures
•Beyond component redundancy− Protects data from array failure− Synchronous replication− Configure on a per-volume basis− Configure on-the-fly, no down time
High availability− Multiple disks, controllers, or arrays− Zero disruption of data access− Ensures “high availability” for data

• The goal for SAN availability is "no nines," or 100% availability. (Gartner,2007)
• Human error and firmware bugs are the weakest links, even in properly deployed SANs. (Gartner, 2007)
SAN/iQ Multi-site SANReal-time protection from site failure
•Protect Storage By:− Racks− Room− Floor− Building− Site
•Keep Data Online During:− Facility disruption− Natural disaster− Site maintenance

SAN/iQ Thin ProvisioningRaise storage utilization, increase return on investment, and reduce costs•Cost Savings− Purchase only what you need
today− Allocate only as data is written− No reserve necessary− Integrated with SmartClones,
Snapshots and Remote Copy
•Delay Future Storage Purchases− Grow capacity as warranted
•Simple to Manage− Enable/disable with radio button on
per-volume basis

SAN/iQ SmartCloneCost efficient volume copies that allow for quick provisioning
Realize cost savings through cloning• No duplicate data, only changes are
stored• Ideal for storing system images• Instant provisioning of volume copies
for test and development• Testing can be done with real data• No impact to production
SmartClone Volumes
SAN/iQ Cluster
SAN/iQ SnapshotsPoint-in-time, space-efficient snapshots for backup and recovery
•Simplified Backup and Recovery− Point-in-time volume copies− Scheduled, ad hoc or scripted
•Functional− Volume rollback− Recover granular data− Backup integration
• Microsoft VSS• VMware VCB
•Space Efficient− Thin provisioned always− Delta changes only− No snap reservation
