Thank you Matt for the response,
We actually are trying the PAE switch based on a discussion with Citrix
Consulting. They say this is a good general purpose setup for 9-12gb of ram,
after that you will run into kernel memory issues. We don't over commit CPU's
or memory so we are ok there.
One question, you commit all 8 CPU's to VM's , You don't leave at least 1 for
XenServer?

PAE actually makes term server run poorly with most application sets. I would
definitely recommend disabling it.

Best 32 bit/W2K3R2 setup I have found is 2vCPU/4GB RAM for each VM. Make sure
you don't overuse cores. there shouldn't be anymore vCPU's than cores on your
physical server. Memory shouldn't be overcommitted either (I reserve 2GB RAM
for XenServer). On a 24GB Dual Quad (not Nehalem) blade I comfortably get (4)
Citrix server VM's with the config above.

8 gb ram with PAE turned on.
Getting a 3-1 consolidation of this config. Our apps are memory starved and not
CPU.

Subject: [THIN] Citrix and VMWare
Hi all, does anyone have any guidelines for Citrix VM servers on ESX 4.0?
I currently have 5 Windows 2003 R2 PS 4.5 servers on ESX 4.0. They are
assigned 1 virtual CPU and 2GB of Memory.
They're all spiking up to 100%CPU for extended periods of time with about 15
users each. Should I have 2 CPUs or 4?
Any other advice would help.
Thanks,
