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 the 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.
