Resource pools are sometimes used the wrong way. In this free paper called Top 6 Tips for Configuring vSphere Resource Pools you’ll learn to understand what are resource pools and how to configure them right.
Resource pools are very powerful, but when setup right. If not, they can affect performance of your infrastructure. Remember that if there is no resource contention, vSphere does not use resource pools to manage resources. Only during periods of resource contention (under load) the resource pools comes into play.
You can drag & drop VM to resource pool. The Memory, CPU, Shares or Limit of that VM don’t change immediately, but when you start the VM only. Also, the resources present in the resource pools are not affected, only when the new VM which came in is Powered ON. If Resource pool cannot guarantee to allocate the reservation for this VM, an error is generated.
