The ESXi server has a default resource pool called Resources that defines normal
resources for a virtual machine.

## Before you begin

Role required: admin

## About this task

Resource levels are dynamically generated from shares of the total
resources allocated to virtual machines on the ESXi server. For details about how
these resources are calculated, review the VMware Knowledge Base <https://www.vmware.com/>. ServiceNow
Discovery finds this default resource pool and adds a record to the ESXi Resource
Pools module automatically. If Discovery is not running on the ServiceNow instance, create a record for the
Resources pool. Ensure that the
Owner field is correct and leave the resource fields
blank. If a provisioner selects the Resources pool when
provisioning a virtual server, the ESXi server will create a virtual machine for use
under a normal load.

## Procedure

1. Navigate to AllVMware CloudConfigurationESX Resource Pools.
2. Click New in the list.
3. Create a new record for each resource pool in the ESXi server, ensuring that the Name and Owner fields are correct.
4. Select the CPU expandable and Memory expandable check boxes to allow for expansion of the CPU and memory limits when needed, if those resources are available on the ESXi server.  
   When granted, these extra resources can be revoked if needed to provision
   other virtual machines. The additional fields on the form are for display
   purposes only.
5. Click Submit.
