Dear team,
I have cisco ucs b-200 m3 blade server with below configuration. I want to know how to check NUMA Node on ESXi host.
RAM:192
Socket 2 (8 cores each).

Unfortunately it seems NUMA is disabled hardware-wise. You can only enable it via BIOS setting.
Use the following: esxcli hardware memory get | grep NUMA or esxtop
How to check if NUMA is enabled on ESX hardware?
Hi,
it can be done by checking esxtop while it is running if you follow this article: Sizing VMs and NUMA nodes - frankdenneman.nl. If the processors are Intel Xeons, there is always 1 NUMA node / socket. Also the VMkernel writes the NUMA mapping out to vmkernel.log during boot-time.
Edit: This is from vmkernel.log at the boot-time
TSC: 949659 cpu0:0)ACPI: 366: 2 nodes found in SRAT table
TSC: 952962 cpu0:0)NUMA: 370: 2 real nodes found
Also you can find the NUMA node layout in the Advanced VM properties. See my blog post http://vmxp.wordpress.com/2014/10/29/stress-testing-an-esxi-host-with-windows-server-vms/ - it's the first image there ![]()
thanks Richardson,
ran this command esxcli hardware memory get | grep NUMA below is the output what does it mean
~ # esxcli hardware memory get | grep NUMA
NUMA Node Count: 1
request u to confirm NUMA is enabled or not

This isn't right.. do you have memory interleaving enabled or disabled in BIOS?
thanks Alistar,
I don't have any idea about memory interleaving is enabled or not, is there any way to check without reboot , with the help command we can check this.
if I ran the esxtop in that it show the below
request u to confirm NUMA is enabled or not.
