What is the difference between vSwitch and Dvswitch?
A standard vSwitch works within one ESX/ESXi host only. Distributed vSwitches allow different hosts to use the switch as long as they exist within the same host cluster. A distributed vSwitch extends its ports and management across all the servers in a cluster, supporting up to 500 hosts per distributed switch.
