Will the desktops be running somewhere else, or on the x4600s? I'm
assuming you want to keep Windows below.
There's an absolute limit of 192 VMs per ESX host, and given that you
want to be able to have at least one ESX host die without affecting
service, that means that you would be looking at 6.25 users per VM along
with implementing shared storage of some description for VM failover.
Local storage is essentially negligible if you want to use VMware HA.
Aside from whatever OS solution, you're looking at a RAM allocation
of about 214MB per user. If the VMs are to run on the x4600s, I don't
think there's any way you could seriously do that on two x4600s if your
users are anything like mine.
If you want to add SGD as well, that's kind of not a big deal against
running the desktops for everyone.
