Performance Analysis & Review VDI + SBC.

Independent & Unbiased.

Latest Gear.

VDI Hypervisor 7 7 AD File Share Logging

Office 2007: Outlook, Word, PowerPoint Excel PDF printer & Adobe PDF Internet Explorer (multiple sites + Flash Video) FreeMind 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 Conclusions Phase 1 & 2.

Phase 3.

VSI vs VRC Optimizations.

VRC optimizations: Standard VSI Tuning.

VRC optimizations: Extra Disabled Services.

VRC optimizations: Scheduled Tasks.

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

VDI + Storage.

‘Red Bull’

VMware vSphere: HaltingIdleMsecPenalty = HIMP Default = 100 ‘Red Bull’

VDI on ‘Red Bull’; Windows XP

“VDI on Red Bull”; Windows 7

Hyper-Threading Disabled

HIMP = VMware vSphere; >> Hyper-V by design fast #LOL 23% Improvement Windows XP 22% Improvement Windows 7 Only on Hyper-Threading HaltingIdleMsecPenaltyMax HIMP Conclussion.

Phase 3 - VSI Results.

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.

Fusion IO.
