3. Other trends driving tiered storage 3 Virtualization Compliance Diversity Complexity

4. Traditional SAN designs bring limited benefits Storage objects are bound to physical resources Statically configured and operated Individual islands of storage within the SAN Performance and capacity resources not easily reallocated Difficult and costly to operate Specialized training and staff Many planned outages for upgrades and migrations Professional services often required Just to get a configuration operating To implement changes Enterprise features require additional software licenses High acquisition and software support costs Costs continue to increase as the environment grows 4

7. Network-based

8. Array-based6

10. More capacity managed per storage administrator

11. Seamless Expansion through Virtualization

12. Freedom from traditional disruptive, fork-lift expansion and upgrades

13. Lean Operations reduce CAPEX

14. Purchase storage on-demand7

17. Seamless scaling of both performance and capacity

18. Investment protection – no fork-lift upgrades

19. Powerful & Simplified Management

20. Intelligent and automated management

21. Perpetual self-optimization

22. Automated load balancing across disks, RAID sets, connections, cache and controllers

23. All-inclusive functionality

24. Enterprise software capabilities included, no add-on licensesEqualLogic can provide storage management manpower savings of 45 days/year – ESG 9

30. EqualLogic PS Series SANs support 3 techniques for tiering storage Auto-Tiering (via Automatic Load Balancing) RAID Preference Configuration Pool-Based Tiering 15

31. Terminology review 16 Volume Thin Provisioning RAID Member Pool IOPS Group SAN HQ

33. Fully automated mechanismEthernet Switch Fabric = + + 17

34. Challenge #2: Certain applications in the data center with special storage needs Suggestion: Configure PS Series RAID Preference Uses Group Manager Advanced volume settings Requires multiple RAID policies within a single pool RAID preference policy will attempt to honor setting 18

35. 19 Challenge #3: Multiple independent user groups that need dedicated storage Suggestion: Use PS Series pooling Pooling mechanism commits arrays to applications or user groups Similar to RAID preference, but policy is enforced, not simply prioritized Ethernet Switch Fabric = + +
