I came across this a couple days ago

100,000 I/O Operations Per Second, One ESX Host

Maxing out 500 15k RPM spindles with a single host. I didn't think
that was even possible. Granted this is ESX and not VMware server
(previously known as GSX), but ESX is pretty cheap these days,
the foundation version gets you a ton of stuff minus hot migrations
for $999(per 2 proc) (used to be about $3750). I think the
enterprise edition (~$5k per 2 proc) is overkill for most uses.
