vSphere vMotion allows you to move an entire running virtual machine from one physical server to another, without downtime. The virtual machine retains its network identity and connections, ensuring a seamless migration process. Transfer the virtual machine's active memory and precise execution state over a high-speed network, allowing the virtual machine to switch from running on the source vSphere host to the destination vSphere host. This entire process takes less than two seconds on a gigabit Ethernet network. This capability is possible over virtual Switches, vCenter Servers, and even long distances.
