BlueField DPU Management Capabilities

The following subsections describe the recommended management methods for specific tasks on the BlueField DPU .

The NVIDIA BlueField DPU offers two methods for performing software upgrade: The standard ISO format or the BlueField bootstream (BFB) file format.

  • Update and recovery

    • The BFB serves both as a comprehensive upgrade tool and a recovery solution for the DPU. To facilitate these upgrades and recovery tasks, the BlueField DPU's BMC is under the control of a remote management controller (RMC) that utilizes the Redfish protocol over the 1GbE OOB connection.

    • A pre-installed golden image can be used which allows flash and recovery of the DPUs. This can be triggered by either the RMC or a trusted platform's BMC. For more information, refer to this page.

  • Update

    • A PXE server may be used to load an ISO image which contains the necessary updates. This can be accomplished over the 1GbE OOB interface or through the high-speed data ports using the DPU's UEFI.

Warning

After an upgrade/recovery, a system power cycle may be required to apply changes.

The DPU BMC can be updated by the RMC using Redfish over the 1GbE OOB port to the DPU BMC.

DPU BMC update is A/B redundant, using a dual firmware flash. If both flashes fail to boot, the DPU BMC may be recovered from the platform's BMC using the SMBus or UART interfaces.

Please refer to this page for more information.

Warning

After an upgrade, a system power cycle may be required to apply changes.

The RMC may monitor and read telemetry of the BlueField DPU using Redfish over the 1GbE OOB port to the DPU BMC.

  • BlueField DPU temperatures (board, DDR, and ports), voltages and link states

  • BlueField DPU FRU information about NIC FW, CPU, DDR, eMMC, network interface, etc.

  • Device sensor data record (SDR), sensor threshold and events, system event logs (SEL), etc.

Please refer to this page for more information.

The RMC may issue a reset to the BlueField DPU (soft or hard) or to the DPU BMC, both using Redfish over the 1GbE OOB port to the DPU BMC.

Please refer to these pages (1,2) for more information.

BlueField DPU UEFI settings may be modified using Redfish over the 1GbE OOB port to the DPU BMC. This includes changing UEFI default password (which is mandatory), setting DPU to zero-trust, setting date and time, etc.

Please refer to this page for more information.

The DPU console interface is accessible via the DPU BMC using Serial-over-LAN (SoL) over the 1GbE OOB port. The RMC may access the console interface of the BlueField DPU to track its boot progress.
