After you install a network adapter that supports RDMA (RoCE v2) on your ESXi host, use the vSphere Client to review the RDMA adapter and a physical network adapter.


  1. On your ESXi host, install an adapter that supports RDMA (RoCE v2), for example, Mellanox Technologies MT27700 Family ConnectX-4.
    The host discovers the adapter and the vSphere Client displays its two components, an RDMA adapter and a physical network adapter.
  2. In the vSphere Client, verify that the RDMA adapter is discovered by your host.
    1. Navigate to the host.
    2. Click the Configure tab.
    3. Under Networking, click RDMA adapters.
      In this example, the RDMA adapter appears on the list as vmrdma0. The Paired Uplink column displays the network component as the vmnic1 physical network adapter.

    4. To verify the description of the adapter, select the RDMA adapter from the list, and click the Properties tab.
