Configuring PCIe Options

You can configure the bandwidth splitting option of the encoding card to achieve optimal performance and compatibility in various application scenarios.

1. On the BIOS setup screen, choose Advanced > PCIe Config.
2. On the PCIe Config screen, configure PCIe splitting options first.

   Set the bandwidth splitting option of the slot where the NETINT Quadra card is installed to x4. For example, if the NETINT Quadra card is installed in slot 3, set Slot3 BandWidth Splitting to x4.

   

3. Save and exit BIOS configuration.
4. Access the server OS. Run the nvme command to check whether the PCIe splitting function takes effect.
   1. Optional: The NETINT encoding card uses the NVMe protocol. If NVMe is not installed in the environment, install it.

      1	yum install nvme-cli

   2. After installing the NETINT encoding card, run the following command to check whether the card is correctly identified:

      1

      nvme list

      If information similar to the following is displayed, the NETINT card is correctly installed. The command output is only an example.

   • One NETINT Quadra card has two chips, corresponding to two device nodes. The preceding output shows one NETINT Quadra card, which corresponds to two device nodes.
   • One T432 (x8) card has four chips. Therefore, the bandwidth after bandwidth splitting is x2. For example, if the T432 card is installed in slot 3, set Slot3 BandWidth Splitting to x2.
