vSphere supports hierarchical resource pools (parent and child pools) for CPU and memory resources on individual hosts and across hosts in a cluster. They allow for resource isolation and sharing between pools and for access delegation of resources in a cluster. Please note that DRS must be enabled for resource pool functionality if hosts are in a cluster. If DRS is not enabled the hosts must be moved out of the cluster for (local) resource pools to work. This license level has host only resource pools as vCenter Server is not included.
