      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;it can be done by checking esxtop while it is running if you follow this article: &lt;A href="http://frankdenneman.nl/2010/02/03/sizing-vms-and-numa-nodes/" title="http://frankdenneman.nl/2010/02/03/sizing-vms-and-numa-nodes/"&gt;Sizing VMs and NUMA nodes - frankdenneman.nl&lt;/A&gt;. 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.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Edit: This is from vmkernel.log at the boot-time&lt;/P&gt;&lt;P&gt;TSC: 949659 cpu0:0)ACPI: 366: 2 nodes found in SRAT table&lt;/P&gt;&lt;P&gt;TSC: 952962 cpu0:0)NUMA: 370: 2 real nodes found&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Also you can find the NUMA node layout in the Advanced VM properties. See my blog post &lt;A href="http://vmxp.wordpress.com/2014/10/29/stress-testing-an-esxi-host-with-windows-server-vms/" title="http://vmxp.wordpress.com/2014/10/29/stress-testing-an-esxi-host-with-windows-server-vms/"&gt;http://vmxp.wordpress.com/2014/10/29/stress-testing-an-esxi-host-with-windows-server-vms/&lt;/A&gt; - it's the first image there &lt;img id="smileyhappy" class="emoticon emoticon-smileyhappy" src="https://communities.vmware.com/i/smilies/16x16_smiley-happy.png" alt="Smiley Happy" title="Smiley Happy" /&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Unfortunately it seems NUMA is disabled hardware-wise. You can only enable it via BIOS setting.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
