How much CPU resources are reserved for the ESXi hosts? I have a cluster that shows total CPU resources is 672 GHz in the Summary tab, but when I go to the Resource Allocation tab, the total capacity is only 624 GHz. I am basically losing 2 whole cores per ESXi host in the cluster. Memory on the other hand is nearly identical.
its an expected behavior. Please find the details in following KB.
the different is because an esxi host is treated as a resource pool when you see at cluster level.
