ESXi Memory Modules

I'm trying to find out how many memory modules there are on our ESXi hosts without bringing the host down and physically looking.  I know the total amount of memory, but I don't know if it's using all of the memory slots.  Is there a command to run in cli or does it tell you somewhere in the vsphere client?  

Thanks!

Look on the Hardware Status tab, expand Memory and it should list all the DIMMs

Good Luck

The Hardware Status tab should tell you, but not sure if it shows 'empty' slots...mine are all filled.

Sign your company up to try the MB 660 headset now

Take control and stay focused in noisy open office environments with the MB 660. By reducing background noise, you can revitalize your office and improve concentration.

That works great for servers that are in vCentral.  What about stand alone ESXi server?  There isn't a hardware tab.  Configuration > Memory just shows the total.

There is no way to do this. You can either compile dmidecode and grab it from SSH OR open the case while the server is hot and count the open slots.

No problem coolsport00 - I am not sure about that either as mine are also all occupied. However when I expand any DIMM is does show the capacity - might either (1) not show up, or (2) show the slot as unoccupied, ie. 0GB

The only other way to 'see' your DIMM slots that I'm aware of is by installing SNMP software within your host -> e.g. Dell OpenManage or HP Insight Manager; no native way without vCenter I believe.

Then OpenManage may be your only bet here "acronie" :(

That information is available through CIM (Common Information Model). That is how vCenter Server gets its information about hardware health. There are a number of applications that work with the CIM broker in ESX or ESXi - some are free, others are not, and there are evaluation versions available for a number of those that aren't free.

Take a look at http://searchservervirtualization.techtarget.com/tip/0,289483,sid94_gci1324222_mem1,00.html for some ideas.

Good Luck
