Of course stripping everything possible from the Guest XP host will help considerably. It is likely that there are lots of services and drivers you can take out since all they do is log on to run that one app. If the app will run on an older OS that will help - even an unpatched XP without any service packs would be smaller. tim -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Greenberg Sent: Wednesday, March 01, 2006 11:38 PM To: thin@xxxxxxxxxxxxx Subject: SPAM-LOW: [THIN] Re: Scalability of VMWare workstation 5 on PS Tim, Thanks for answering the question and avoiding questioning the question! Yes, we have tried everything possible with this app including AIE, virtual IP/Loopback, Softricity, etc. It is a very low overhead application that is basically run once, logs into a call center processing system to re-direct the phone line and then just sits there while the agent works. Disk access, RAM, CPU, etc are negligible. The only real impact will be the base RAM is takes to run the VM itself. It is currently running on MS Virtual PC on Citrix at this site. Moving to ESX is the leading option, but it adds a layer of cost and complexity which is not ideal for this client's environment. ESX with Virtual Center and V Motion would add 30K to the project and we are exploring using those same hardware boxes to simply add more app servers to the farm and publish M workstation instead.

In your (customer) situation running a few virtual servers that will be desktop OS's will be OK - assuming the host has sufficient Memory. I typically keep 8-10 virtual OSs up on any given box with "reasonable" performance. If the app itself does a lot of disk access then disk speed becomes important, but it really is a memory thing that is most limiting. Not optimal, but you said you didn't want to get into that, and I know that you clearly are familiar with application virtualization which would be the more obvious alternative choice. tim -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Greenberg Sent: Wednesday, March 01, 2006 4:56 PM To: thin@xxxxxxxxxxxxx Subject: SPAM-LOW: [THIN] Scalability of VMWare workstation 5 on PS Does anyone have any scaling feedback on running VMWare workstation 5 on PS as a published app serving up XP desktops? # of sessions per server, etc. would be helpful Please don't respond to debate the merits, this is for a customer project in which a single app will be run from these XP instances and it must be done this way!!!! thanks Steve Greenberg Thin Client Computing 34522 N.
