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.
