Raid 0 on a virtual mechine host box?!depends on what you wanna do with it. For now our VDI runs on HP DL580 G5 (freaking old stuff with Xeon 7400s) with 64-384GB RAM, depending on the host, and a few RAID0s (whoever designed that should be killed). Only one host is a DL580 with Xeon E5s. Users usually don't complain about the speed, even with 40-60 VDIs on one host.
Sounds like someone said give me speed or give me death on that build
