I've been informed that what would have been my companies new server of choice, the IBM x3500 M4 does not support Windows 2003 at all.
The reason I am quoted is "Both Intel and Microsoft do NOT support W2k3 on both the new Romley EP (i.e. x3550 M4) and Sandy Bridge EP (x3500 M4)"
I can't find anything on Hp about the G8 servers to confirm or deny this either.
Does anyone have any decent links or articles that actually verify this?
