I came across this a couple days ago http://blogs.vmware.com/performance/ May 22, 2008 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. nate
