Users can create child resource pools of the root resource pool or of any user-created child resource pool.

Each child resource pool owns some of the parent’s resources and can, in turn, have a hierarchy of child

resource pools to represent successively smaller units of computational capability.

A resource pool can contain child resource pools, virtual machines, or both. You can create a hierarchy of

shared resources. The resource pools at a higher level are called parent resource pools. Resource pools and

virtual machines that are at the same level are called siblings. The cluster itself represents the root resource

pool. If you do not create child resource pools, only the root resource pools exist.

In the following example, RP-QA is the parent resource pool for RP-QA-UI. RP-Marketing and RP-QA are

siblings. The three virtual machines immediately below RP-Marketing are also siblings.

For each resource pool, you specify reservation, limit, shares, and whether the reservation should be

expandable. The resource pool resources are then available to child resource pools and virtual machines.

Create a Resource Pool

You can create a child resource pool of any ESXi host, resource pool, or DRS cluster.

NOTE If a host has been added to a cluster, you cannot create child resource pools of that host. If the cluster

is enabled for DRS, you can create child resource pools of the cluster.

When you create a child resource pool, you are prompted for resource pool attribute information. The

system uses admission control to make sure you cannot allocate resources that are not available.

Prerequisites

The vSphere Client is connected to the vCenter Server system. If you connect the vSphere Client directly to a

host, you cannot create a resource pool.

Procedure

1 In the vSphere Client inventory, select a parent object for the resource pool (a host, another resource

pool, or a DRS cluster).

2 Select File > New > Resource Pool.

3 Type a name to identify the resource pool.
