You must choose whether to use vSphere standard switches or vSphere distributed switches for networking.

With vSphere standard switches, each server has its own virtual switch: a vSphere standard switch handles network traffic at the host level in a vSphere environment. A vSphere standard switch can route traffic internally between virtual machines and link to external networks.

A vSphere distributed switch treats the network as an aggregated resource, reducing the administrative burden resulting from per-host virtual switch configuration management. The single VDS spans multiple hosts at the datacenter level.

A vSphere distributed switch maintains port statistics regardless of virtual machine location or vMotion migration history. With standard switches, such statistics are kept on a per-virtual-port basis and are lost during events like a vMotion migration.
