| VMWare seems to work better for the 2 servers I implemented virtualization in. It just seems to be more responsive and I would think that definitely had something to due with it utilizing the hardware more effective/efficently at the physical level so the VMs all have optimum resources.
We ran 1 domain controller, 1 exchange server and 1 Microsoft ISA server in 3 VM's on a 1TB SAS Raid 5 with 8GB of ram and dual quad core zeons. Only thing that was a little tricky was the IP addressing but iirc it magically cleared itself up with a patch from intel for the mobo.
