I'll second that. We run TS on W2k3 on top of ESX 3.5 and we don't let much more than 30 users logon per TS instance if we can help it. I'm running 19 users on one TS right now and am seeing 25%-45% CPU utilization, and most of those users are only running Citrix apps or IE. Two virtual CPUs are assigned to the TS, and 3.75 Gigs of RAM.

You will reach limitations in Terminal Server long before you run out of resources on that monster Server. For 100 users you may find you need 3 Virtual Terminal Servers if they all connect at the same time.

Now TS on VM Q's too I am not a TS person and have only ever setup 1 pure TS in my career. I would advise looking at the recommendation from Project: Virtual Reality Check. They will give you unbiased info/data on what works best for configuration details. Project: VRC has gotten so influential that Microsoft, Citrix, VMware, HP and other vendors now use the VRC scripts for all their testing and design white papers. VMware has gotten burned by VRC in the past and had to fix major bugs in their software. Several VMware public fixes were originally private fixes specifically for TS issues that VRC found. Of course, the two guys heading up VRX are fellow CTPs! :) Thanks Carl Webster Citrix Technology Professional http://dabcc.com/Webster From: David Lum [mailto:[email protected]] Subject: RE: Terminal Server or VPN? Now TS on VM Q's too Andrew this is actually my thinking. Licensing is quite cheap (under $2K for 100 seats), a purchase req got submitted this week - I am fortunate that $2K is quite small beans in light of the other costs of this move. My next question is - given an 8CPU 64Gb RAM host system (times two), does it make sense to have more than 1 TS Server VM per physical host? ESX is the VM host softwware, so I don't know if it make sense to have 1 monster 64-bit VM per physical system or have 2-3 per. I'm thinking one big TS VM per side saves overhead of additional VM systems. Thoughts, comments? I do have the 2008 TS Resource Kit and while excellent, it doesn't cover VM's thoroughly enough to answer that question. I have TS Web access working internaly, and a basic TS 2K8 server up, the practice I don't have is TS Gateway. I think I can get there in 3-4 weeks and have some testing time, but we'll see... ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ________________________________ Any medical information contained in this electronic message is CONFIDENTIAL and privileged.
