NVIDIA Mellanox MBF2H516B-CENOT BlueField-2 100GbE Dual-Port DPU with 16GB DDR4: This is a BlueField-2 BF2500 series Data Processing Unit (DPU) controller card with two QSFP56 ports rated at 100GbE each, an integrated 8-core Arm Cortex-A72 processor, 16 GB of onboard DDR4, and a PCIe Gen4 x16 host interface. The corresponding NVIDIA P/N is 900-9D205-0056-ST2. This is a full DPU — programmable smartNIC plus Arm compute — not a passthrough adapter or basic NIC. This is a new unit.
Engineering Context
BlueField-2 combines the ConnectX-6 Dx network controller with an 8-core Arm Cortex-A72 SoC, allowing infrastructure services (storage, security, networking) to be offloaded from the host x86. The 16 GB of onboard DDR4 supports the embedded OS (DOCA / Ubuntu) and offload workloads. The card supports hardware-accelerated cryptography, regex, and storage emulation (NVMe-oF target/initiator, virtio-blk emulation). The PCIe Gen4 x16 host interface provides the bandwidth headroom for 200Gb/s aggregate Ethernet at line rate.
Deployment & Use Cases
Zero-trust security offload (firewall, IDS/IPS) at the network edge. NVMe-oF storage gateways and virtio-blk emulation. SDN data-plane acceleration with OVS offload. Bare-metal-as-a-service host isolation for cloud providers. AI cloud infrastructure offload alongside ConnectX-7 / NVLink GPU networks.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MBF2H516B-CENOT
NVIDIA P/N: 900-9D205-0056-ST2
Series: BlueField-2 BF2500
Network Controller: ConnectX-6 Dx (integrated)
Ports: 2 x QSFP56
Ethernet Rate: 100GbE per port (200Gb/s aggregate)
Arm SoC: 8-core Cortex-A72
Onboard Memory: 16 GB DDR4
Host Interface: PCIe Gen4 x16
Software Stack: NVIDIA DOCA, BlueField OS
Form Factor: HHHL PCIe card
Condition: New — Factory sealed, supplied by T.E.S IT-SOLUTIONS
Compatibility & Constraints
Requires a host with a PCIe Gen4 x16 slot for full bandwidth; will operate at reduced speed in PCIe Gen3 slots. The card runs the BlueField OS / DOCA stack and is programmed via the integrated Arm cores; it is not a drop-in basic ConnectX-6 NIC unless explicitly placed in NIC mode. Requires QSFP56 cables or transceivers for 200Gb/s aggregate; QSFP28 cables negotiate down to 100Gb/s aggregate (50GbE per port-pair lane). Not compatible with PCIe Gen2 systems.
