# Broadcom adapter setup for WEKA system

Before a WEKA system can use a Broadcom BCM57508-P2100G, the server must have the necessary drivers and firmware from Broadcom's download center.

## **Set up the drivers and software**

**Procedure:**

1. **Download software bundle**: Access Broadcom's download center and download the software bundle onto the target server. Carefully review the instructions included in the bundle.
2. **Compile and install**: Follow the provided instructions to compile and install the following components:
   * `bnxt_en` driver.
   * `sliff` driver.
   * `niccli` command line utility.
3. **Post-installation steps**: After installation, run one of the following commands based on the Linux distribution:
   * `dracut -f`
   * `update-initramfs -u`
4. **Reboot the server**: Reboot the server to apply the changes.

## **Install the firmware**

After installing Broadcom drivers and software, install the firmware included in the download bundle. Firmware files are typically named after the adapter they are intended for, such as `BCM957508-P2100G.pkg`.

**Procedure:**

1. **Identify the target adapter**: Use the command `niccli --list` to list Broadcom adapters and identify the target adapter by its decimal device number:

```shell
# niccli --list
----------------------------------------------------------------------------
Scrutiny NIC CLI v227.0.130.0 - Broadcom Inc. (c) 2023 (Bld-61.52.25.90.16.0) 
----------------------------------------------------------------------------
     BoardId     MAC Address        FwVersion    PCIAddr      Type   Mode
  1) BCM57508    84:16:0A:3E:0E:20  224.1.102.0  00:0d:00:00  NIC    PCI
  2) BCM57508    84:16:0A:3E:0E:21  224.1.102.0  00:0d:00:01  NIC    PCI
```

2. **Identify the device**: From the `niccli --list` output, choose the device identifier (for example, `1` for `BCM57508`).

```
# niccli --dev 1 install BCM957508-P2100G.pkg
```

3. **Confirm and complete the installation**: Follow the prompts to confirm and complete the firmware update.

{% code overflow="wrap" %}

```shell
Broadcom NetXtreme-C/E/S firmware update and configuration utility version v227.0.120.0
NetXtreme-E Controller #1 at PCI Domain:0000 Bus:3b Dev:00 Firmware on NVM - v224.1.102.0
NetXtreme-E Controller #1 will be updated to firmware version v227.1.111.0

Do you want to continue (Y/N)?y

NetXtreme-C/E/S Controller #1 is being updated....................................................
Firmware update is completed.
A system reboot is needed for the firmware update to take effect.
```

{% endcode %}

4. **Reboot the server**: Reboot the server to apply the firmware update.

## **Update NVM settings**

To enable WEKA system compatibility, configure certain NVM options to increase the number of Virtual Functions (VFs) and enable TruFlow.

**Procedure:**

1. **Increase the number of VFs to 64**: Run the following commands:

   ```shell
   niccli --dev 1 nvm --setoption enable_sriov --value 1
   niccli --dev 1 nvm --setoption number_of_vfs_per_pf --scope 0 --value 0x40
   niccli --dev 1 nvm --setoption number_of_vfs_per_pf --scope 1 --value 0x40
   ```
2. **Enable TruFlow**: Run the following commands:

   ```shell
   niccli --dev 1 nvm --setoption enable_truflow --scope 0 --value 1
   niccli --dev 1 nvm --setoption enable_truflow --scope 1 --value 1
   ```
3. **Additional configuration for BCM57508-P2100G**: Run the following command:

   ```shell
   niccli --dev 1 nvm --setoption afm_rm_resc_strategy --value 1
   ```
4. **Reboot the server**: Reboot the server to apply the changes.

The adapter is ready for use by the WEKA system.
