I’d agree with that. It’s REALLY cool technology but if you spread your VM’s carefully across a VMware farm, much in the same way you would physical boxes, you could easily get by just fine if a VMware server went down (scheduled or not).
Not to mention, it’s a HUGE cost increase to get the extra VI3 features. Compared to the foundation bundle which is ESX, VCB, and VirtualCenter Agent, it’s 3x more to get vMotion HA and close to 6x more to get the full blown package which has vMotion, HA, DRS, and Storage vMotion. Then you need to add VirtualCenter Server on top of all that to even use vMotion/HA/DRS.
Those are some massive costs that would likely make VMware not available to fit into a lot of people’s budget, but the Foundation bundle is pretty darn cheap in and of itself, giving you the core product, and at rock bottom price. A price that is low enough that anyone could get VMware ESX into their environment, IMO.

I don’t understand why shared storage is a necessity for virtualizing Citrix. HA, vMotion and DRS are way oversold features that are nice to have but not necessary for virtualizing PS/XenApp.

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 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are just a tad out of date.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.
