Configuring PCIe Options

On the BIOS settings page, choose Advanced > PCIe Config.
On the PCIe Config screen, configure PCIe splitting options.
Set Slot3 BandWidth Splitting and Slot6 BandWidth Splitting to x2. (The encoding cards locate in slots 3 and 6.)
After configuring the splitting options, restart the system for the configuration to take effect. After confirming that the configuration takes effect, go to the next step.
You can run the nvme command to check whether PCIe splitting is implemented.
The NETINT encoding card uses the NVMe protocol. If NVMe is not installed in the environment, install it.
```
apt install nvme-cli
```
After installing the NETINT encoding card, run the following command to check whether the card is correctly identified:
```
nvme list
```
If the following information is displayed, the card is correctly installed:

A NETINT T432 card has four chips, corresponding to four nodes. The following figure shows two NETINT T432 cards, which correspond to eight nodes. /dev/nvme4n1 is not an encoding card.
On the BIOS settings page, choose Advanced > PCIe Config. On the PCIe Config screen, set the PCIe max payload size. On the CPU 0 PCIe Configuration and CPU 1 PCIe Configuration screens, set Max Payload Size to 512B for all PCIe ports.
