Ethernet QSFP56 Interfaces
The network ports of the BlueField-2 BF2500 DPU Controller are compliant with the IEEE 802.3 Ethernet standards listed in Ethernet traffic is transmitted
through the cards' QSFP56 connectors.
QSFP56 Port Over-current Protection
The power consumption for each QSFP56 module is controlled by a 5W current limiting power distribution switch. Every power limiting switch is controlled
by a signal, which is enabled by default. This signal is originated from the thermal shutdown mechanism. When the output load exceeds the current limit
threshold, the power switch limits the current to a safe level.
PCI Express Interfaces
The PCI Express bus is a high-speed interface used to connect the DPU Controller to other peripheral devices (the BMC, PCIe switch or directly to the NVMe
SSDs backplane), and operates as a Root-Complex (RC) initiating PCIe bus operations. The BlueField-2 BF2500 DPU Controller supports PCI Express Gen
3.0/4.0 (1.1 and 2.0 compatible) throughx16 edge connector whichserves as the main interface of the card. This connector enables the connectivity of
the system to the BlueField-2 PCIe interface.
The following lists PCIe interface features:
PCIe Gen 4.0 and 3.0 compliant, 2.0 and 1.1 compatible
2.5, 5.0, or 8.0, or 16.0 GT/s link rate x16
Auto-negotiates to x8, x4, x2, or x1
Support for MSI/MSI-X mechanisms
DDR4 Memory
The BlueField-2 BF2500 DPU Controller incorporates one on-board DDR4 memory sized 16GB, 64-bit data and 8-bit Error Correcting Code (ECC) memory.
The following lists the supported DDR4 data rates:
