VMware vSphere AMP cluster requirements

The management cluster requires VMware HA and VMware vSphere Distributed Resource Scheduler (DRS) for two reasons. The first is to provide VM protection against a VMware ESXi host failure. The second is to balance VM workloads in the cluster.

The following rules are applied to the DRS:

  • Anti-affinity rules are applied to the management cluster to ensure that each VMware NSX-T Data Center manager appliance runs on its own host where possible.
  • Too few hosts may prevent each VMware NSX-T Data Center manager appliance to run on its own host. If so, HA allows the VMware NSX-T Data Center manager appliances to co-exist on the same host.
