Dennis,
Thanks for the info. I'm running (currently) four virtual machines on ESX,
two in test, two in production. Because VMWare does not support SMP on NT,
I've throttled the load balancing to roughly 3/4ths the number of users we
get on a single physical dual proc box. We haven't maxed the box out yet.
I'll let you know when we do, along with the specs and total number of users
we are supporting on our quad ESX box.

Subject: [THIN] VMWare ESX testing
Just thought I would share this with the list. I have been testing VMWare
ESX and Citrix MetaFrame.
For those that are interested, I have a Citrix server running on a Windows
Server 2003. Citrix has the Citrix Server Testing Kit (CSTK) that I have up
and running. Using this kit, I have been able to simulate connections to
this server.
Here are the results:
---
All references to Office Products mean Office 2000.
These tests may not exactly equate to real world work because all
connections are performing work all the time, nobody ever takes a break or
sits and reads the latest joke in email.
---
128M RAM - Single 3ghz processor - no hyper-threading enabled in the VM
13 users running Excel, Word and administrative apps (Command prompt,
terminal services admin, task manager, etc) before they started having
issues.
(RAM was the bottleneck)
512M RAM - Single 3ghz processor - no hyper-threading enabled in the VM
23 total user connections before issues
15 users running Excel, Word and administrative apps
8 users running Excel and Access
(Processor was the bottleneck)
512M RAM - Single 3ghz processor - hyper-threading enabled in the VM
30 total connections with no issues - probably could get more but I didn't
have it configured
20 users running Excel, Word and administrative apps
10 users running Excel and Access
(Processor was the bottleneck)
---
For what it's worth, in our current environment, which I have not run these
tests, I am happy to be able to get 30 users on a NT 4.0 TSE server with
4Gig RAM and dual 1.14ghz processors.

What's keeping you from getting more from your terminal servers? Did you
know, in most cases, CPU Utilization IS NOT the single biggest
constraint to scaling up?! Get this free white paper to understand the
real constraints & how to overcome them. SAVE MONEY by scaling-up rather
than buying more servers.
