Port binding for NVMe over RDMA involves creating a switch and connecting the physical network adapter and the VMkernel adapter to the switch. Through this connection, the RDMA adapter becomes bound to the VMkernel adapter. In the configuration, you can use a vSphere standard switch or a vSphere distributed switch.

The following diagram displays the port binding for the NVMe over RDMA adapter.

For more information about creating switches, see Create a vSphere Standard Switch or Create a vSphere Distributed Switch in the vSphere Networking documentation.
