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

NSXT-VI-VC-009

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.
