1. BEST Overall Storage for Virtual Environments* *Nemertes Research 2008 PilotHouse Virtualization Awards

2. Agenda • Introductions • EqualLogic Value proposition • Overview of EqualLogic architecture • Live Demonstration • Clone VM • Grow SAN performance and capacity • Create DR playbook • Questions???

3. Abstracting the logical view of the storage from the physical view Intent is to mask underlying complexity for productivity gains Benefits Reduce cost and complexity Enhance performance tuning Enable online data migrations Simplify storage provisioning Optimize capacity utilization Centralize and simplify storage and data management Seamless scalability STORAGE VIRTUALIZATION Architectures • Host-based • Network-based • Array-based

4. EQUALLOGIC PS SERIES VIRTUALIZED iSCSI SANS • Mission Critical Hardware that Provide: • End-to-end reliability • On demand scalability • Enterprise Software Features that Deliver: • Easy set-up • Single-view management • Rapid provisioning • Optimized performance • Seamless expansion • Comprehensive data protection • Flexible online tiering

5. Simplifies Networked Storage Uses more affordable hardware and existing infrastructure Leverages ubiquitous networking knowledge Enhances Consolidation ROI Simplifies virtual server deployments Reduces acquisition, deployment and ongoing management costs Enables a Simple Virtualized Storage Architecture Natively supports virtualization primitives Allows scalable, flexible networked storage grid implementations Load balances across all SAN resources WHY iSCSI IS IMPORTANT TO VIRTUAL INFRASTRUCTURES iSCSI SAN IDC's Top Storage Predictions: Virtual servers will emerge as the killer application for iSCSI

8. CUSTOMER TREND: VIRTUAL SERVERS MEET VIRTUAL STORAGE A Cost Efficient, Scalable and Resilient Infrastructure for Both Servers and Storage Ethernet Fabric Physical Infrastructure Virtualized Assets

9. Purchaser must Estimate frame size to support requirements over the product life cycle Results in Greater upfront cost due to over-provisioning and/or Disruptive and costly upgrades due to under-provisioning Buy only resources needed for initial deployment Non-disruptively expand as capacity / performance needs arise New resources automatically applied to pre-existing workloads No downtime, no forklift upgrades Amortize costs over total system life Non-Disruptive “Pay As You Grow” SAN Expansion Classic Storage Architecture Frameless Storage Architecture Fixed storage expandability, performance and I/O Cache Controller Performance Performance Number of disks Disk Drives configured in RAID sets Number of disks

10. HIGH STORAGE UTILIZATION VIA VIRTUALIZED VOLUMES • In contrast to classic storage arrays, volumes are not mapped to RAID groups • Volumes are striped across all the disks in the array • Unallocated space is consolidated in a logical pool ESX Server VMFS2 VMFS1 VMFS3 iSCSI Initiator Ethernet Switch Fabric VMFS1 = VMFS2 VMFS3

11. HIGH AGGREGATE PERFORMANCE WITH NO TUNING EFFORTS • Automatically apply SAN resources where and when needed • Controller resources grow as storage grows • Automatic striping across entire pool of storage • Automatic load balancing across all SAN resources ESX Server VMFS2 VMFS1 VMFS3 iSCSI Initiator Ethernet Switch Fabric VMFS1 = + + VMFS2 VMFS3

12. AutomaticTiering Across Storage Tiers • Economic Benefits of Storage Tiering • Save $$$’s on capital investments • Buy the right storage tier for the application • Efficiently meet service level requirements • Data placed on the right storage tier to deliver optimal performance • Reduce environmental costs • Lower total expenditures on power and cooling by making use of lower RPM disk drives Hi-performance apps 15K HDDs 10K HDDs Performance apps • Lower • $/GB • Power 7200 HDDs Mainstream apps Archival, backup Single SAN view

13. THIN PROVISIONING HELPS REDUCE CAPITAL OUTLAYS Standard Physical Provisioning Physically Allocated, not in use Allocated, in use Thin Provisioned Volume Additional virtually allocated storage to application Physically Allocated, not in use Allocated, in use • Thin Provisioning • Method of assigning virtual storage volumes to applications and consuming physical capacity on demand • Economic/Environmental Benefits • Eliminate much of standard provisioning costs • Buy storage later, as you need it • Improves storage utilization • Reduce power costs • fewer disks spinning, less cooling needed • Manpower savings in time spent provisioning volumes • Management Benefits • Avoid server disruptions due to growth procedures • Centralized management • Eliminate 80% of server reprovisioning • Prioritize staff time away from provisioning grunt work

14. Greater Efficiency Through vSTORAGE API integration GOAL: Leverage the SAN to optimize storage functions CHALLENGE: Coordinate between ESX and Storage Arrays Group Manager Virtual Center SAN Fabric API’s • Available today for Dell EqualLogic • Auto-Snapshot Manager/VMware Edition • VMware Site Recovery Manager Adapter • Advanced engineering • SAN accelerated provisioning • Snapshot processing • SAN accelerated Storage VMotion • Thin provisioning • Advanced multipathing
