VSI workload (14 minute loop)
Phase 1 & 2.
• Virtualization TS/XenApp: Yes we can!• Sweet spot = performance + licensing
• Best-Practices•No vCPU overcommit + 2vCPU minimum•Dedicated Host / Reservation, Enforce vMMU! (x86 - vSphere)
• Intel Nehalem/Westmere: impressive•Hyper-Threading + EPT-D = Doubling Capacity

“…Project VRC must emphasize that it is crucial to test and validate these
optimizations in your own VDI deployment…”

Conclusion I/O’s.
• Windows 7 more than Windows XP• Boot• First Loop
• Windows 7 less than Windows XP• Second Loop• Idle
• Best practice: • Use ‘VRC’ Optimizations• fix page file• A/V
Conclusion I/O’s

VMware vSphere:
• HaltingIdleMsecPenalty = HIMP
• Default = 100

A-Team
• VSIMax
• Local vs Streaming
• I/O Impact
Phase 4: Impact AppVirt on VDI
• 3 major AppVirt vendors:• Citrix Application streaming•Microsoft App-V•VMware ThinApp
• Office 2007 suite virtualized as 1 package
• Different scenario’s: streamed, precached, shared cache
AppVirt on VDI: test setup
“Project VRC’s goal is to investigate overall performance impact of AppVirt in VDI.”
“Project VRC does not recommend virtualizing the Microsoft Office suite as an overall
best practice.”
• Maximum users on a host
VSIMax results
App-V vs. Local installed %
• Impact VSIMax: ~24%
• Different configurations doesn’t impact VSIMax
App-V conclusions
streamed vs. Local installed %
Bug > Fix!
Pre-cached vs. Local installed %
Bug > Fix!
VDI + Storage - IOPS.
IO reads: stream vs. local %
IO reads: cached vs. local %
IO writes: stream vs. local %
IO writes: pre-cached vs. local %
Worst/worse case scenario or reality?:
• Impact VSIMax: -24%
• Streaming apps = 22-45% less READ IO’s
• Streaming apps = 20-45% more WRITE IO’s
• Check response times in whitepaper (release soon)
• Application Virtualization IS key in Optimized (virtual) Desktop
Appvirt: Conclusion
VDI + Storage - IOPS.
