Hence my statement of lightly used servers.  Most companies care about
getting more users on a system vs less.  Now granted the OP didn't say how
many users, how many servers but in the end if you try to take an entire
farm and port it to VM's, you will typically end up using more VM's than
phsyical boxes.  VM's simply cannot get the same amount of users on a system
as physical hardware can at this point in time.  If you aren't utilizing
your servers to their full potential or even close to their potential, then
yes you could move to VM's and not notice much of difference.  But let's be
realistic for a moment, most people move to VM's to consolidate servers.  As
well, many many companies that do this with Presentation Server aren't using
their boxes to nearly their potential anyways so moving to VM's for that
reason is simply ridiculous.  I would be willing to bet that many PS
implementations have never taken the time to benchmark or stress test their
servers to see how many users they can get on a system.  They have no idea
what their sytems can handle and therefore over buy on the systems
required.  Now overbuying isn't necessarily a bad thing (for redundancy) but
I've been into many many companies that do it because they simply don't know
what their systems can handle.

whew, gotta get off that soapbox.  Sorry everyone

  Jeff,



Respectively I hope that you are only taking about highly utilized
production Citrix servers and not other servers as VMs. There are many
companies including where I work that have production VMs of various sorts
and flavours. ESX is absolutely a production ready product that is capable
of running production VMs. Yes there will be servers that have too high of
utilization to be running on ESX but there are tons of over powered
underutilized servers out there.

I believe the general concesus is is that for production, VM's are not the
way.  Lightly used servers are fine, but for an entire farm the performance
is ismply not there yet.

Currently running FR3 on 2000 SP4, and am beginning to evaluate and look
at building a separate Windows 2003 CPS 4.0 Farm on the VMWare ESX
platform.  Just wanted to get an idea if anyone on the list has something
similar in production today, what hardware you deployed to support published
apps on ESX and VMotion, and how you designed your farm (including Data
Collector and Database).  Also looking for Best Practices and Things to
Avoid!



Thanks!!
