Load Balancing #vSphere Clusters with DRS
Recently, a customer reported that DRS was not working to load balance the cluster. Under normal circumstances, a minor imbalance is nothing to be concerned about. This is because the main objective for DRS is not to balance the load perfectly across every host. Rather, DRS monitors the resource demand and works to ensure that every VM is getting the resources entitled. When DRS determines that a better host exists for the VM, it make a recommendation to move that VM.
