VMware HA Slot is the default admission control option prior to vSphere 6.5. Slot Size is defined as the memory and CPU resources that satisfy the reservation requirements for any powered-on virtual machines in the HA cluster.This article is just to cover how the HA slots are calculated step by step not more than that.
Unfortunately, this scenario is not covered in the VMware Availability guide, but I was told it would require a single step of configuring static routes on Active and Passive nodes. I will cover this step in the vCenter Server High Availability Review – Part 2.

With the Host Failures Cluster Tolerates admission control policy, vSphere HA ensures that a specified number of hosts can fail and sufficient resources remain in the cluster to fail over all ...
Calculate Host Failure Requirements - buildvirtual.net Failover Slots – the number of slots reserved for failover. 137 in this example, as we have configured the cluster to allow for a single host failure. There are a number of things to bear in mind when using ‘Host failures the cluster tolerates’ as the admission control policy. VMware: Fixing Insufficient resources to satisfy configured…
