“Built for Business Continuity”

3. Background
Technology leader
•
− Founded in 1999 as LeftHand Networks
− A recognized leader in iSCSI SANs
− More than 11,000 installations
− Many Patents
− Ranked as “Visionary” Gartner’s Magic Quadrant
− Only SAN vendor to ship solutions with VMware
All inclusive feature-set focus
•
− “Pay-as-you-grow” architecture
− Performance
− Scalability
− Availability
− Simple management

4. LeftHand SAN product family
Competitive Differentiators
•Cost-effective high availability
•Scalable performance
•Simplified management for virtual environments
Five Key Features
1. Storage Clustering
2. Network RAID
3. Thin Provisioning
4. Snapshots
5. Remote Copy

5. Storage requirements
Performance
• Must support dynamic workloads concurrently
Scalability
• Scale capacity and performance linearly
• No forklift upgrades or disruption
Availability
• High availability: Data remains online when disaster strikes
• Disaster recovery: Data is recoverable after a disaster strikes
Manageability
• Simple to administer

6. LeftHand SAN advantages

7. 5 features with every LeftHand SAN
& use with Vmware
• Scalable performance and capacity
Storage Clustering Maps to VMware DRS
• Beyond the box availability
Network RAID Maps to VMware VMotion
Thin Provisioning • Reduce costs, increase capacity utilization
• Data protection, tape storage reduction
Snapshot Maps to VMware VDI with SmartClones
• Disaster recovery via integrated replication
Remote Copy Maps to VMware SRM - Site Recovery Mgr.

8. SAN/iQ Storage Clustering
(Maps to VMware DRS)
True clustering brings reliability, performance, and ease of management
Storage clustering SAS
− Aggregates critical components
− Data is load balanced
− Predictable scalability
Grow on your terms
− Scale-out storage
− Non-disruptive
− Throttle bandwidth
SATA
Storage tiering
− Optimized for type of data
− Online volume migration
Simple centralized management
− One step server-volume mapping Centralized Management Console
− Integrated Performance Manager

9. SAN/iQ Network RAID
(Highest Level of Availability Locally)
Always on storage, data remains accessible during site failures
SAN/iQ Cluster
Beyond component redundancy
A D A D
− Protects data from array failure
− Synchronous replication A B A B
− Configure on a per-volume basis
− Configure on-the-fly, no down time C B C B
C D C D
High availability
− Multiple disks, controllers, or arrays
− Zero disruption of data access
− Ensures “high availability” for data
The goal for SAN availability is quot;no nines,quot; or 100% availability. (Gartner,2007)
•
Human error and firmware bugs are the weakest links, even in properly
•
deployed SANs. (Gartner, 2007)

10. SAN/iQ Multi-site SAN
(Maps to VMware VM-HA & VMotion)
Real-time protection from site failure
Protect Storage By:
