HA uses the highest CPU reservation of any given VM and the highest memory reservation of any given VM. If VM1 has 2GHZ and 1024GB reserved and VM2 has 1GHZ and 2048GB reserved the slot size for memory will be 2048MB+memory overhead and the slot size for CPU will be 2GHZ. Now how does HA calculate how many slots are available per host? VMware Slot Size - The IT Hollow Memory Component: 49 GBs / 80 MBs = 627 slots . We take the lower value between the CPU slot size and the memory slot size to determine the number of virtual machines that can be started up under admission control. So therefore we could safely start 384 machines on these ESXi hosts, have one fail, and have the other host start all of them.
