The typical scenario is to place vCenter Server in a vSphere HA cluster. HA will protect vCenter Server just like any other virtual machine. If the ESXi server that is running vCenter Server goes down, HA will kick-in and power on this VM from the shared storage on another HA cluster member host. Calculate Host Failure Requirements - buildvirtual.net You can view detailed information on the slot size for a cluster, and how many slots have been used and are left available by clicking the ‘Advanced Runtime Info’ link on the cluster’s summary tab: In the example above we can see that: There are three nodes in the cluster, and all are currently available Understanding Total Slots, Used Slots & Available slots in ... Available slots = Total slot – Used slots i,e Available slots = 234 – 6 = 228. It should come as 228 as available slots but why Available slots is 150 in the above snapshot. Is that wrong or VMware did something wrong in HA slot calculation? Absolutely NOT. Below is the method of calculation for Total Slots, Used Slots & Available slots. Slot sizes - Yellow Bricks ignored host with 100 slots [considering worst case scenario, if it fails]and summed up the slots in the remaining hosts and concluded 200 slots. 1. say, we have 5 hosts with different memory and have mem slot sizes as 30, 40, 50, 60, 70.
