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.
