My understanding Exchange 2K7 is recommended to sit on a GC designated domain controller (so it has quick access to the global catalog), but would it sit on the same box as say, an SMS, WSUS, or SQL server? Anything you WOULDN'T have it share a host with?

All running on ESX 3.5. You should get new Dell server guys if they can't quantify that statement. A properly configured VM running on a properly configured ESX server (can't speak for Hyper-V) and properly sized should see no noticeable performance hit. Just as in the physical world you gotta make sure you understand your current environment and size accordingly, with emphasize on storage and memory. There are at least a couple of whitepapers on Exchange 2007 performance on ESX; HP and maybe Dell. I would say take a look at those, test in your environment with your type of workload and use that data to make your decision. -alex On Mon, Apr 28, 2008 at 5:37 PM, Dennis Melahn <[EMAIL PROTECTED]> wrote: Anyone virtualized Exchange 2007? I'm getting mixed opinions. My Dell server guys are saying performance would suffer too much. I also have a local integrator who is a VMware and MS Gold Partner and says they virtualize everything and that because my information store is only about 25GB for approx 150 boxes I wouldn't have performance problems. Thoughts?
