What is true about resource pools created on a Distributed Resource Scheduler (DRS) cluster?

The root resource pool is not created with administrator-specified values; its capacity is automatically derived from the aggregate physical resources of the cluster's member hosts.

vCenter Server automatically creates a root resource pool at cluster formation time, and its size is dynamically computed as the sum of all CPU and memory resources contributed by every ESXi host in the cluster. This root pool serves as the mandatory parent container for all child resource pools and VMs within the DRS cluster. Its values are never manually specified - they update automatically as hosts are added to or removed from the cluster.

The root resource pool represents the combined resources of the ESXi hosts within that specific DRS cluster only, not the aggregate resources of all hosts or clusters across the entire datacenter.

A root resource pool is always automatically created when a DRS cluster is formed and is required as the top-level parent for all resource pools and workloads within that cluster.
