A cluster is a group of hosts. When a host is added to a cluster, the host's resources become part of the cluster's resources. The cluster manages the resources of all hosts within it. Clusters enable the VMware High Availability (HA) and VMware Distributed Resource Scheduler (DRS) solutions.

Open vSphere Client session to a vCenter Server.

Verify that you have sufficient permissions to create a cluster object.

Verify that a Datacenter, or folder within a datacenter, exists in the inventory.
