It had 2 Quad core processors and 32GB of RAM. I had the system up running only Hyper-V and 6 VMs all on the RAID 5 with few issues attributable to hardware. The VMs were AV, SQL, AD, IIS/Print/FTP, File type of machines. Backups were done using native 2008 image based backup to a 1TB USB drive. I would think that you should be fine with the RAID 5. I would put the system on a separate RAID 1 60GB drive if it was me. I hate putting VM's on the same drive as the OS. It works but I still hate it.

(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/> ~
