Determine memory modules installed without looking inside the box

Question

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.

dmidecode run in dom0 or the host should be able to tell you what memory modules you have.

As of ESX 3.x, dmidecode output is included in the vm-support if the utility is there. – Chris Sep 10 '10 at 12:33
+1 Good call on dmidecode – gWaldo Sep 10 '10 at 17:41
dmidecode works well on both ESX Server and XenServer so thanks, question answered. Pipe the output into a file and search for "DIMM" finds the memory information – Rob Nicholson Sep 14 '10 at 10:13

If the server is a HP, I'd say to check the iLO or the System Management Homepage (SMH). (You did install the PSP, didn't you...?)

I'm sure other brand-name servers have similar Lights-Out management info available, too...

I'll confirm that this info is available on Sun servers through their iLOM cards as well. – EEAA Sep 10 '10 at 13:14

dmidecode is now deprecated. For ESXi 5+ consider using smbiosDump.
