VMWare, processors
I know I have asked this before, but I need to clarify
The Summary page of my Host reports the following:
When I allocate vCPU to my VM, I have the following options:
So if I want my VM to fully utilize the machine, I would perform the following even though the number of Logical Processors on the host is 32. Is this correct ?

what is the maximum number of sockets you can add on your host?
if you want to FULLY utilize ALL processors, add them ALL!

Like hanccocka said doing this is a NO GO without proper testing as adding more vcpu's to a vm will not increase the performance. Especially if you have more vm's on the same machines.
So for theoratical purpose. I never combined this all as i never had the need for more then 4 vcpu's per vm.

Yes, I get that this is a no go, but I am trying to get a handle on VMWare, and what a vCPU is
Is a vCPU essentially 1 core
Since the machine has 2 soeckets, 8 cores per socket, hyperthreading enabled, and 32 LOGICAL processors, if I want to max out the resources do I assign 16 vCPU or 32 vCPU

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
if you have 32 Cores available = 32 vCPUs
if you have 16 cores = 16 vCPUs
but your VMware license dictates how many you can use, and anything less than Enterprise is 8.

Can your Virtual Machine support 32 vCPUs?
Normally you would add 1 vCPU to the virtual machine, and test, if the performance is not good enough for you would add another vCPU.
Just because you can add multiple vCPUs to a VM, does not mean that you have to.
Adding many vCPU can be detrimental to the performance of a VM, because of vSMP.
