ESXi supports RDMA capable network adapters. After you install such an adapter on your ESXi host, the vSphere Client displays its two components, the RDMA adapter and a physical network adapter.

You can use the vSphere Client to view the RDMA adapter and its corresponding network adapter.

Prerequisites

Install a RDMA-capable adapter that supports RDMA (RoCE v2) on your ESXi host. For example, Mellanox Technologies MT27700 Family ConnectX-4.

Procedure

  1. On your ESXi host, install a RDMA-capable adapter that supports RDMA (RoCE v2).
    The host discovers the adapter and the vSphere Client displays its two components, an RDMA adapter and a physical network adapter.
  2. Navigate to the host.
  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.
