Very true...PVS (and other thin provisioning solutions) are gonna turn the
computing world on its side. Citrix had better start evangelizing PVS much more
before other vendors catch up. And they will, quickly.

This is an excellent point and this is exactly why Provisioning Server is such
a strong play, it is just taking a while to penetrate into the market place, it
allows you to bypass the expensive SAN storage requirements for PS servers

Virtualizing Citrix usually means you have to pay for two new things that you
didn't have to pay before: the virtualization layer (ESX) and shared storage.
Does the server hardware savings make up for the additional cost of these other
items? For non-Citrix servers the answer is normally "yes" since most are
underutilized. Citrix servers are not underutilized so you probably won't get
much savings from hardware consolidation.
Some people say: "we have already invested in VMware and the SAN and have
excess capacity", thus not considering those costs. I think this is a fallacy
since the costs will be paid eventually if you add anything else to the system
and wish you had the extra capacity that is now being used by the Citrix
servers.

The balloon driver is actually called the 'Memory Control Driver', and
you can choose to not install it as part of the vmware tools. The
settings at the bottom are ESX host configuration settings, located in
'Advanced Settings' on the 'Configuration' tab of a host in Virtual
Center.
Hope this helps...ormond

The tips at virtrix.blogspot.com <http://virtrix.blogspot.com/> refer to a
memory ballooning driver in
VMWare tools that I can't seem to locate. I think that some of those
tips
are just a tad out of date.
And then there's this which is mostly a copy of the virtrix.blogspot
page
but with additional information at the bottom:
http://knmi.wordpress.com/best-practices-for-deploying-citrix-on-esx/
Now if I can just figure out what all that stuff at the bottom is...

if you are virtualizing Citrix you are going to get less people on per
virtual machine. Count on about 30. Here is a link to some Citrix tips
on
VMware.

Anyone else have some tips?

Subject: [THIN] Virtualizing Citrix
Hi all,
I see all these messages going back and forth about virtualization, but
not much information on how Citrix/TS behaves in a virtualized
environment.
A tech./sales person from Dell came yesterday and told me that I could
probably replace 7 of my PowerEdge 2850 with one beefed up PowerEdge
R900 and virtualize the 7 Citrix servers. I find that kind of hard to
believe.
Each of my 2850's can handle about 30 to 40 users concurrently. I just
don't think that an R900 could handle 200 + users with virtual Citrix
servers.
Is anyone out there using VMWare to virtualize Citrix servers in a
production environment?
What kind of hardware?
How many virtual servers per physical server?
How many users?
I would greatly appreciate your advice as I am new to VMWare.
