А compute cluster uses a single vSphere distributed switch whose design includes traffic types on the switch, number of required NICs, jumbo frames configuration, port groups settings, and Network I/O Control settings.

A compute distributed switch handles networks for NFS, management, vMotion, VXLAN and vSAN.

You also design the configuration of the physical NICs, NIC teaming and VLAN IDs.
