vCpu Pcpu Slots are confusing

[heygokul]

Hi

This could be a redundant topic, I tried searching in threads but could not find an answer to my question.

I have a cluster with 8 hosts.

Each esx host has 2 quadcore CPU, 32GB RAM.

I want to know when I calculate the slots for CPU would it count the cores(which in this case is 8).

What would be my slot size, I need to know this for HA failover.

Cpu slot. = total cpu esx host / 256 mhz * max virtual cpu (with reservation it’s the highest reservation plus the max memory overhead)

Am I right in placing the calculation as

Cpu slot = 240000 (8cores * 30000mhz) /256mhz * 12000 max vcpu(this is because of reservation for 4*3000 CPU).

Output of the above 11250000.

I am certain the calculation is incorrect. Could someone advise what I am calculating wrong

Regards

GKL

Did you already read http://www.yellow-bricks.com/vmware-high-availability-deepdiv/ ? This post explains HA and admission control in detail.
