Creating a resource pool in our vSphere product family has always been a pretty straight-forward task. With the introduction of vSphere 5.1 and the new Web Client, the task is still straight-forward but it is accomplished in a slightly different way.
As the Web Client presents new ways of interacting with, managing, and administering your vSphere environments, the majority of our videos relating to the vSphere 5.1 Web Client are geared towards providing you with a nice and short means of familiarizing and orienting yourself with the new Web Client.
We will have more technical and complicated videos relating to vSphere 5.1 coming in later months; for now, we will be focusing on demonstrating how to accomplish the various tasks within the vSphere Web Client.
This tutorial video discusses and demonstrates creating a resource pool in the vSphere 5.1 Web Client.
Resource pools are used to hierarchically partition available CPU and memory resources of a standalone host or a cluster. You can use resource pools to aggregate resources and set allocation policies for multiple virtual machines, without setting resources on each virtual machine.
You can create a child resource pool of a standalone host, resource pool, vApp, or DRS cluster. You cannot create resource pools in a cluster that is not enabled for DRS. The system uses admission control to make sure you cannot allocate resources that are not available.
After the resource pool is created, virtual machines can be added to it. A virtual machine’s shares are relative to other virtual machines (or resource pools) with the same parent resource pool.
