I'm redesigning some of my network and have everything set up as virtual machines on a test server. SBS 2008 and an XP client behind a virtual Vyatta router all on a Dell 2900 with 5x73GB SAS RAID, dual quad core Xeon processors. Everything works, even MS Exchange. My next step is to set up Openfiler for an iSCSI storage solution. Eventually, my network will never go down. NEVER EVER. Not that I'm getting carried away or anything.
Ha, a little confidence never hurt anyone. So you're testing your new config on virtual machines currently? I'm guessing that your running a RAID5 with the OS and Data on the same volume. iSCSI is brand new to me, I stopped paying attention for about a year and a half and I might as well not know anything these days
