I've got 3 HP/Compaq boxes running hyper-v. Raid 1 for the OS, and raid 5 for the vms. As long as the write caching is enabled, performance has be pretty good.
If that write caching is not on, pretty dog slow.

(dual quad core with 48GB RAM) The Hyper-V guests i'll be putting on here are really going to just be old physical servers that i want to retire. So not much production use. There will be a few important servers, like some Win2k3 IIS SMTP servers, but not too much traffic. Also a test domain that has Exchange on it with only 2 active mailboxes. stuff like that. Hard Drive config? I was thinking of doing Raid 10 initially with all drives, but i'd be without a hot spare. Not liking the idea of getting a spare ahead of time or waiting for one if i didn't. I was then thinking of Raid 5 with a hotspare.. But i am nervous about the possible write bottleneck. I just want to get as much space as i can, but not suffer the wrath of my guests. Has anyone had a similar config like this with Hyper-V and done Raid 5 with SAS drives? -BenN ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
