When you power on a virtual machine in a cluster, DRS places it on an appropriate host or generates a recommendation, depending on the automation level you choose.
When a virtual machine experiences an increased load, VMware DRS automatically allocates additional resources by redistributing virtual machines among the physical servers in the resource pool.
VMware DRS also allows users to define the rules and policies that decide how virtual machines share resources and how these resources are prioritized among multiple virtual machines.
