vSphere 6 - vCPU calculation question

ac427

You have a ESXi 6 Host with six 32 core CPU's and 256GB ram

What is the maximum number of vCPU's you can assign to a single VM ?

So you have 192 cores total - but 128 is the maximum number of vCPUs per VM - so it's 128.

But, it would be good practice to keep the number of vCPUs within your NUMA node size - whatever that may be within your system architecture.

Thanks Scott, I wondered why it was not 192.

I remembered there was something in the configuration maximums PDF about 32 vCPU's.
