From watching the exchanges on the list. It seems the only two
signifcant benefits are the following:
Consolidating under used servers - If you want 2 or more CSG and NFUSE
and domain controllers in a farm for five hundred users it's a way to do
this with one or two servers. This would also be great for patching \
rebooting these servers. You don't reboot the actual box, you just
reboot the guest OS on VMWARE. The VMWARE box just happily runs on.
Fault Tolerance - With the right version of VMWARE you can lose an
entire server (of any type) including a Citrix server according to one
poster. And the server will fault over to it's redundant one with no
notice to the users (including no dropped Citrix sessions). I actually
really want to see this work :) Maybe at Brian Madden's conference in
DC? It just sounds to cool to believe. None of my customer's really
require that kind of ultimiate redundancy (that's what silos are for),
but it sounds great.

I have a question about this. I'm all for Vmware (especially ESX).
But, what is/are the major driving factors to use Vmware for MetaFrame?

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.
