Leveraging data center bridging (DCB) capabilities as well as advanced congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks. RDMA and RDMA over Converged Ethernet (RoCE)ĭPU, utilizing IBTA RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged Ethernet) technology, delivers low-latency and high-performance over Ethernet networks. DPU effectively addresses this by providing advanced NVGRE and VXLAN hardware offloading engines that encapsulate and de-capsulate the overlay protocol.
While this solves network scalability issues, it hides the TCP packet from the hardware offloading engines, placing higher loads on the host CPU. In order to better scale their networks, data center operators often create overlay networks that carry traffic from individual virtual machines over logical tunnels in encapsulated formats such as NVGRE and VXLAN. The BlueField-2 DPU integrates eight 64-bit Armv8 A72 cores interconnected by a coherent mesh network, one DRAM controller, an RDMA intelligent network adapter supporting up to 200Gb/s, an embedded PCIe switch with endpoint and root complex functionality, and up to 16 lanes of PCIe Gen 4.0. FRU I2C address is (0x50) and is accessible through the PCIe SMBus.ĮMMC - x8 NAND flash (memory size might vary on different DPUs) for Arm boot, OS and disk space.ĭDR4 SDRAM - 8GB/16GB/32GB single-channel DDR4 SDRAM memory. FRU EEPROM - Stores the parameters and personality of the card.Quad SPI NOR FLASH - includes 256Mbit for Firmware image. IEEE 802.1Q, 802.1P VLAN tags and priority.IEEE 802.3ap based auto-negotiation and KR startup.IEEE 802.3by, Ethernet Consortium25, 50 Gigabit Ethernet, supporting all FEC modes.The adapters comply with the following IEEE 802.3 standards: 200Gb/s / 100Gb/s / 50 Gb/s / 40 Gb/s / 25 Gb/s / 10 Gb/s / 1 Gb/s.
Uses PCIe Gen 4.0 (16GT/s) through an x8/x16 edge connector. If anything is missing or damaged, contact your reseller. Prior to unpacking your DPU, it is important to make sure you meet all the system requirements listed above for a smooth installation. Be sure to inspect each piece of equipment shipped in the packing box.

BlueField-2 DPU also supports CentOS and has an out-of-band 1GbE management interface. For more information, please refer to the DOCA SDK documentation or NVIDIA BlueField-2 Software User Manual. It should be part of system wiring or it can be ordered separately as a system accessory.īlueField-2 DPU is shipped with Ubuntu – a Linux commercial operating system – which includes the NVIDIA OFED stack (MLNX_OFED), and is capable of running all customer-based Linux applications seamlessly.
NOTE: The power cable is not included in the package. P-Series DPU controllers with PCIe Gen 4.0 x16 require additional 75W through a supplementary 6-pin ATX power supply connector. Minimum 75W or greater system power supply for all cards. X8 or x16 Gen 4.0 slot as per the PCIe interface with specified for the card. The DOCA SDK makes it easy and straightforward to leverage DPU hardware accelerators and CPU programmability for better application performance and security. Sitting at the edge of every server, BlueField-2 is optimized to handle critical infrastructure tasks quickly, increasing data center efficiency. BlueField-2 empowers agile and high-performance solutions for cloud networking, storage, cybersecurity, data analytics, HPC, and artificial intelligence (AI), from edge to core data centers and clouds, all while reducing the total cost of ownership. The NVIDIA DOCA software development kit (SDK) enables developers to rapidly create applications and services for the BlueField-2 DPU.
