12. Sample 70K user XA project Project goals Determine the maximum user density per square foot attainable for a large Siebel roll-out Project constraints Timeline Internal resource assignments from other groups (Siebel team, proj mgmt group, nw team) Hardware provided (1) DL580 (2) DL380

13. Assumptions A solid Siebel back-end platform for high interactive would be readily available throughout, using the Call Center HI QA environment for testing Network connectivity would remain solid throughout Written scripts existed for the high interactive platform, defining different user types and mix of types in a typical day Number of total users expected would be made available Number of users connecting at any one time would be made available Unique user ids would be made available on the back-end AD user ids would be made available on the front-end

17. Config A DL380 36GB MSTCTXAPP10 – Citrix PVS 5.6 DL380 36GB MSTCTXAPP11 - W2K8 R2, XA6, 32GB PVS image DL580 80GB MSTCTXAPP12 – XS 5.6 host running utility images 271 users can be achieved, and performance remains solid throughout. Memory appears to be the bottleneck, with the cpus showing very little stress, even during the mass logins.

18. Config B DL380 36GB MSCTXAPP10 – Citrix PVS DL380 36GB MSTCTXAPP11 – XS 5.6 host MSVTCTXAPP17,18,19,20,21,22,23,24– W2K8, XA5, 4GB PVS image guest DL580 80GB MSTCTXAPP12 – XS 5.6 host running utility images 342 users can be achieved, and performance remains solid throughout. Memory appears to be the bottleneck within a vm – 50 users appear to be a max number for reasonable performance of each vm. The cpus show no stress, even during the rapid logins.

20. Fewer images to manage

21. Fewer server lisc, both MS & 3rd party

22. Compatibility with most workstation applications

23. Staff more familiar with 32-bit OS

24. Staff more familiar with 32-bit applications

26. IE 32-bit does not operate as efficiently (think WOW or VDM on 32-bit Windows)

27. Large potential load on help desk if server has issue

28. Limited to 4GB natively, and 8GB with PAE

29. Current version of Xenapp6 will not run on 32-bit

31. Q&A

32. “The Desktop is Dead. Long Live the Desktop”
