As the SDDC expands, you can add compute-only clusters. Tenant workloads run on the ESXi hosts in the compute cluster instances. One Compute vCenter Server instance manages multiple compute clusters. The design determines vSphere HA settings for the compute cluster.

Design Justification

Design Implication


Configure vSphere HA to use percentage-based failover capacity to ensure n+1 availability.

Using explicit host failover limits the total available resources in a cluster.

The resources of one ESXi host in the cluster is reserved which can cause provisioning to fail if resources are exhausted.
