Is there a way to determine the physical memory configuration of a server that's running ESX Server or XenServer? If the server was running bare metal on Windows, I'd use the excellent CPU-Z utility which displays information about the slot usage.
This could be a Linux shell question (not my speciality) as that's what I think ESX Server and XenCenter are based around.
Failing this, I'm going to have to take the servers down and look inside the box :-(
Thanks, Rob.
