How VMware HA Works VMware HA provides high availability for virtual machines by pooling them and the hosts they reside on into a cluster. Hosts in the cluster are monitored and in the event of a failure, the virtual machines on a failed host are restarted on alternate hosts. VMware vSphere High Availability Q/A – Collabnix VMware High Availability (HA) uses a mechanism called slots to calculate both the available and required resources in the cluster for a failing over virtual machines from a failed host to other hosts in the cluster. VMware vCenter Server 6.0 Availability Guide VMware vCenter Server 6.0 Availability Guide vCenter Server High-Availability Solutions and Configurations There are multiple solutions for high availability.
