Install the Mellanox OFED driver on the data storage computer NICs in your system.

NI requires the Mellanox OFED 5.8-3.0.7.0-LTS driver for the Mellanox ConnectX-6 NICs in the RF Recording system.

  1. Create a directory that will be used as a workspace for extracting and installing the Mellanox OFED driver.
  2. Using another computer with an internet browser, navigate to the NVIDIA Linux Drivers page from the NVIDIA Website.
  3. Navigate to the MLNX_OFED Download Center and click Archive Versions.
  4. Select the following options:
    • Version: 5.8-3.0.7.0-LTS
    • OS Distribution: Ubuntu
    • OS Distribution Version: Ubuntu 22.04
    • Architecture: x86_64
  5. Select MLNX_OFED_LINUX-5.8-3.0.7.0-ubuntu22.04-x86_64.tgz. If prompted, review and agree to the EULA to begin the download.
  6. Transfer the compressed installer to the data storage computer using your preferred method, such as physical media or SSH.
  7. Move the .tgz file to the workspace directory created in step 1. Do not change the file name.
  8. Extract the installer files by executing the following command in the Linux terminal: 
    tar -xzvf ./MLNX_OFED_LINUX-5.8-3.0.7.0-ubuntu22.04-x86_64.tgz
  9. Navigate into the extracted installer folder, then install the driver by executing the following command in the Linux terminal: 
    sudo ./mlnxofedinstall --dpdk --upstream-libs
    Note The OFED installer may yield warnings or errors indicating that dependencies are not installed or that the firmware on the NICs cannot be updated. This is expected behavior and does not indicate that the installation has failed.
  10. Load the new driver by executing the following command in the Linux terminal: 
    sudo /etc/init.d/openibd restart
