NVIDIA® BlueField® DPUs support configuring network ports as either Ethernet only or InfiniBand only.
BlueField Platform Changes and New Features in 4.15.0
-
Removed the requirement for clear-text credentials during BMC and eROT firmware upgrades via the BFB flow. This update introduces a scalable, trust-based authentication mechanism between the Arm OS and BMC, supporting PLDM and RShim updates universally in NIC mode and for trusted Arm OS deployments in DPU mode.
-
Enhanced the
yumandaptinstallation processes for BlueField-3 to align with the deferred firmware update flow. Firmware updates during installation are now optional, and when executed, avoid immediate system resets by deferring the BMC reset to the next system boot. -
Achieved GA-level support for RedHat integration within the DPF, delivering comprehensive technical support for RHCOS BFB compilation and testing, alongside robust bug resolution and troubleshooting developed in collaboration with RedHat.
-
Enabled NVIDIA signature Secure Boot support for the RHCOS BFB image within the DPF, allowing RedHat environments to utilize signed images for secure deployments and supporting the layered RHCOS installation model.
-
Enhanced the BlueField-3 serialized boot sequence by adding a manual user-space trigger, allowing users to delay the host boot until custom logic verifies all critical DPU services are fully operational.
-
The DPU firmware utilizes a fixed DDR operating transfer rate of 5200 MT/s.
-
Do not utilize UEFI variables or fuse values associated with DDR 5600 enablement to determine memory speed. These values are irrelevant in this release and do not reflect the active hardware state.
-
The fixed speed of 5200 MT/s persists through a BIOS reset.
-
Following a BIOS reset, administrators must perform an additional manual DPU reboot to ensure the memory controller initializes correctly at the 5200 MT/s rate.
-
This DDR memory behavior is strictly limited to the current FUR. Installing any other version will automatically revert the memory behavior to the standard configured speed of that version (for example, 5600 MT/s in older versions).
