3. Virtual Desktops Vs Cloud 2.0 • Both require a maniacal focus on endpoint applications • Each can drive network bandwidth investments that benefit the other • Inexpensive endpoint devices (e.g., iPhones, Droids, iPads, Wyse Thin Clients) • Change the way people interact with information • Continue to drive exponential adoption of both • End user experience will determine the success or failure of agency initiatives around both NetApp Confidential - Do Not Distribute

4. Promises, Promises (Blah, Blah…Cloud; Blah, Blah…ROI) Of course, it promises to “cloudify” the desktop Ease management …save money Better security … Solve world hunger … Expect an ROI of 2-3 years (less, if already well along the path of server, network, storage virtualization) NetApp Confidential - Do Not Distribute

6. Giving People Their Lives Back That was in 2005! Over the next two decades, the Washington, DC, metro area is expected to add nearly 1.7 million households — up 34% That does NOT factor in all the construction (e.g., Mixing Bowl, Metro dig in Vienna, Hot Lanes around the Beltway, new bridges, etc.) Nor does it account for snowstorms :^) NetApp Confidential - Do Not Distribute

7. Giving People Their Money Back BELTWAY BURDEN - The Combined Cost of Housing and Transportation in the Greater Washington, DC, Metropolitan Area ULI Terwilliger Center for Housing, et al, 2009 In 2005: Region-wide, households spend an average of nearly $13,000 on transportation per year 127 million hours of wasted time sitting in traffic 91 million gallons of wasted fuel NetApp Confidential - Do Not Distribute

8. The Time Is Ripe For Telecommuting! • *Depending on whether “household” is defined as 1 or 2 people working per household. • Assuming the 2005 numbers telecommuting could save: • $1,125 - $2,250 / yr / desktop* of lost productivity • $6,500 - $13,000 / yr /desktop* in transportation cost • Including $137.57 / year /desktop in wasted fuel per driver THIS IS MONEY IN YOUR POCKET over and above the savings to the IT organization Based on: • Median salary of $78,000 / household / year (2005) • Average transportation cost of $13,000 / household / year (2005) • 2,116,667 people in 2005 • 60 hours / year /person in traffic in 2005 • 42.99 gallons /year / person in wasted fuel • $3.20 / gallon fuel cost NetApp Confidential - Do Not Distribute

10. Where We’re At Today • Notable Exceptions: • US P&TO – 3000+ Teleworkers (operational 3-4 years) • Military Health Organization – rolling out 55,000 desktops • DIA – Rolling out 10,000+ desktops NetApp Confidential - Do Not Distribute

11. The Challenges • Major operational change – “Layer 8/9 Issue” • Input/Output (I/O) orders of magnitude higher than server virtualization (SV) • Mass deployments (think 10s or 100s of 1000s) • “Herd I/O”, such as boot storms • “But it worked fine in the pilot…” – Need to invest! • Virtual desktops do NOT equal physical ones • Don’t use P2V images – start fresh! • Separate user data from apps and desktop images • Turn off virus scanning and search/index tools • Storage Challenges • “Bloat” & Backup/Restore Challenges – greater than SV • I/O bottlenecks • Cost NetApp Confidential - Do Not Distribute

13. Storage Can Make or Break It! “We caution organizations to lay out a complete data management strategy as part of the plan because the amount of storage (and how it’s backed up) can dramatically affect the capital costs.” - Gartner: “Total Cost of Ownership of PCs vs. Hosted Virtual Desktops”

15. I/O Is Heavily Dependent on User Types and Desktop Virtualization Approach Complexity Power Users Mobile Users Task Workers Knowledge Workers Terminal Services VDI, Application Virtualization VDI, Application Virt., Client Virt. NetApp Confidential - Limited Use

16. I/O Is Heavily Dependent on User Types and Desktop Virtualization Approach Complexity Power Users Mobile Users Task Workers Knowledge Workers 4 IOPS 8 IOPS 12+ IOPS 20 IOPS • Repetitive tasks, fewer applications • Lower performance requirements • Lower storage needs • Limited user flexibility • Less complex • More applications • Higher performance required • Higher storage needs • More user flexibility • More complex NetApp Confidential - Limited Use

17. Storage Impact on Desktop Performance • Steady state traffic is generally dominated by small block random writes (50-80%) • However, there can be frequent, exponentially high small block random reads, which can bring storage controllers to their knees Read data block from disk Disk • It is important to size for both performance (# of spindles) and capacity 17 NetApp Confidential

18. Storage Challenges for Virtual Desktops In addition to Storage costs and performance bottlenecks: Maintaining high availability (no service interruption) Security and control of user data (multi-tenancy on steroids) Lengthy mass deployment timeframes Proper data protection requires separation of desktop images, from applications, user profiles and user data All of this requires careful thought and planning! 18 NetApp Confidential

19. Things To Expect From Your Storage Your enterprise storage should support the following, regardless of hypervisor or desktop client: Redeploy thousands of patched images in minutes Thin clones, thin provisioning and primary data dedupe to reduce “bloat” Write optimization and Intelligent caching (thin clone / dedupe aware) to overcome I/O bottlenecks High performance RAID - double disk failure protection with fewest disks (RAID-10 too expensive) Integrated data protection for images, applications, user profiles and user data, without being a storage expert! Restore in minutes. Thin, block level replication for DR to minimize network bandwidth (providing more bandwidth for desktops) Protect against failures, allow maintenance with minimal service interruption Scale easily to store user data as amount of rich media grows NetApp Confidential - Do Not Distribute

20. Things To Expect From Your Storage Deployments leveraging these storage efficiency features are achieving virtual disk prices that approach $50 / desktop (less expensive than an internal disk in a physical server). Your enterprise storage should support the following, regardless of hypervisor or desktop client: Redeploy thousands of patched images in minutes Thin clones, thin provisioning and primary data dedupe to reduce “bloat” Write optimization and Intelligent caching (thin clone / dedupe aware) to overcome I/O bottlenecks High performance RAID - double disk failure protection with fewest disks (RAID-10 too expensive) Integrated data protection for images, applications, user profiles and user data, without being a storage expert!

21. Summary There is a “perfect storm” of technology trends, business drivers, excuses, needs, etc., that make Desktop Virtualization compelling The real potential ROI is an improvement in the quality of life of the workforce (don’t let IT gobble up all the benefit) End user experience will be the measure of the success or failure of any Desktop Virtualization initiatives! The storage you choose is directly related to end user experience and will either make or break your Desktop Virtualization projects NetApp Confidential - Do Not Distribute
