Using Resource Pools
The settings for VM resource allocation—memory and CPU reservations, limits, and shares—are methods that modify or control how resources are distributed to individual VMs or that modify the priority of VMs seeking access to resources.
In much the same logical way that you assign users to groups and then assign permissions to the groups, you can leverage resource pools to allocate resources to collections of VMs in a less tedious and more effective process. In other words, instead of configuring reservations, limits, or shares on a per-VM basis, you can use a resource pool to set those values on a group of VMs all at once.
A resource pool is a special type of container object, much like a folder, in the Hosts And Clusters view. You can create a resource pool on a standalone host or as a management object in a vSphere DRS-enabled cluster. Figure 11.10 shows the creation of a resource pool.
