VMware HA: Advanced Options - Experts-Exchange I am reviewing the Host Failures Cluster Tolerates Admission Control Policy , which says that it uses a formula to calculate the slot size of all the VMs on a host.

Generally, one virtual machine = 1 used slot. In the example above, I have seven powered on virtual machines and seven used slots in the cluster. To calculate the slot size for a cluster, HA uses the highest CPU reservation of any virtual in the cluster, and the highest memory reservation for any virtual machine in the cluster.

If your cluster contains any virtual machines that have much larger reservations than the others, they will distort slot size calculation. To avoid this, you can specify an upper bound for the CPU or memory component of the slot size by using the das.slotCpuInMHz or das.slotMemInMB advanced attributes, respectively. Host Failures Cluster Tolerates Admission Control Policy - VMware When you select the Host Failures Cluster Tolerates admission control policy, the Advanced Runtime Info pane appears in the vSphere HA section of the cluster's Monitor tab in the vSphere Web Client. This pane displays the following information about the cluster: Slot size. Total slots in cluster.
