Creating a Resource Pool
A Resource Pool is a pool of CPU and memory resources. The resources are allocated based on the CPU and memory shares that are defined and creating one is optional. Why create a Resource Pool? Because it allows you to set allocation policies for multiple virtual machines, without the need to set resources on each virtual machine.
A resource pool can be created in just a few simple steps:
1. Open the vSphere Client
2. Select a cluster then select File -> New -> Resource Pool
3. Enter a friendly name to describe the resource pool, such as “Lab servers” and allocate the resources as you wish. Click OK
4. Drag the required VMs into the Resource Pool as required
