80. A-Team

81. VSIMax Local vs Streaming I/O Impact Phase 4: Impact AppVirt on VDI

82. 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

83. “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.”

84. Maximum users on a host VSIMax results

85. App-V vs. Local installed %

86. Impact VSIMax: ~24% Different configurations doesn’t impact VSIMax App-V conclusions

87. streamed vs. Local installed % Bug > Fix!

88. Pre-cached vs. Local installed % Bug > Fix!

89. VDI + Storage - IOPS.

90. IO reads: stream vs. local %

91. IO reads: cached vs. local %

92. IO writes: stream vs. local %

93. IO writes: pre-cached vs. local %

94. 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

95. VDI + Storage - IOPS.
