Card Removal
Verify that the system is powered off and unplugged.
Wait 30 seconds.
To remove the card, disengage the retention mechanisms on the brackets (clips or screws).
Holding the DPU from its center, gently pull the DPU and Auxiliary Connections card out of
the PCI Express slot.
5.12 PCIe Bifurcation Configuration Options
NVIDIA BlueField-3 DPUs provide a range of configuration scenarios to meet the demands of
environments and deployments. This section describes the various connectivity options for
peripherals on the PCIe, including scenarios where the BlueField-3 DPU acts as the PCIe switch with
NVMe SSDs as PCIe endpoints. While this list of scenarios is not exhaustive, it highlights the tested
and verified options. Customers seeking to support unlisted configurations should contact NVIDIA
Support.
The BlueField-3 DPU exposes two x16 PCIe interfaces, with internal PCIe switch architecture. The
first interface is exposed via the x16 PCIe Gen 5.0/4.0 Goldfinger connector and serves as an
endpoint to the host server by default. The additional PCIe x16 interface is exposed through the
Cabline CA-II Plus connector, featuring programmable bifurcation as a downstream port. The
following figure demonstrates the BlueField-3 DPU block diagram with the PCIe interfaces.
BlueField-3 DPU Block Diagram with PCIe Interfaces
PCIe bifurcation is supported starting from DOCA 2.5 with BlueField BSP 4.5.0 (released
December 2023).
