How do I determine the physical DIMM configuration on and ESX blade server?


I have a few blades running in an IBM Blade Center with a few DIMM slots empty, and I want to order some new RAM to increase the memory. Only problem is, I can't remember the physical layout of the RAM inside the machine. I have 16GB, but is that 8x2GB or 4x4GB? I don't know!!

Is there a command that I can use in ESX to determine what my physical DIMM config is?

I do have the option of turning the blades off and actually opening them up, but that should be a last resort, as there are people who require these blades for development work almost all the time.

I've already tried using dmesg (which only gives me the following: RAMDISK driver initialized: 256 RAM disks of 64000K size 1024 blocksize). Maybe that in itself is the answer to my problem, but I can't figure out how to read that other than to determine the total RAM already in the machine. I've also tried using lshw (which doesn't seem to exist) and i've checked the /proc/meminfo file (which also seems to provide me with only the total memory, though maybe I'm missing something important there too).

In the past I've used lshw and IIRC it had each RAM slot with how much RAM was in each slot. I had to run the command as root though. Oh, and it wasn't installed by default on my debian box, but was in the repositories.
