NVIDIA Mellanox® MBF2H536C-CECOT — BlueField-2 P-Series DPU 100GbE Dual QSFP56 32GB
Technical Identity
The NVIDIA Mellanox® MBF2H536C-CECOT is a BlueField-2 P-Series Data Processing Unit (DPU) pairing an 8-core ARM Cortex-A72 SoC with an integrated ConnectX-6 Dx networking engine. It delivers two 100GbE QSFP56 ports, 32GB of on-board DDR4, and a PCIe Gen4 x16 host interface. Hardware-accelerated offloads — RoCE v2, NVMe-oF / NVMe/TCP, IPsec, TLS, OVS, and DOCA-based services — run at 100GbE line rate per port. The card ships with an integrated BMC, Secure Boot Enabled, Crypto Enabled, 1GbE OOB management, in an FHHL form factor with Tall Bracket. Condition: Refurbished Grade A — EEPROM-verified, BMC-checked, cosmetically inspected, EU stock.

What This Is NOT

NOT a standard NIC. Full DPU with ARM cores, on-board DDR, and integrated BMC — runs an independent Linux OS.
NOT SFP56 or SFP28. QSFP56 ports only. For 25GbE SFP56 BlueField-2 DPU see MBF2H332A-AECOT.
NOT Crypto Disabled. Crypto Enabled — verify export compliance for destination country.
NOT supplied with cables or transceivers — order QSFP56 DAC / AOC / optical transceivers separately.
NOT a switch. Endpoint DPU — pairs with NVIDIA Spectrum-2/3 or compatible 100GbE QSFP56 switch on the network side.

Compatibility & Constraints

Host: PCIe Gen4 x16 slot (Gen3 x16 backwards compatible at reduced bandwidth).
Network: 100GbE QSFP56 switches — NVIDIA Spectrum-2 (SN3000 series), Spectrum-3 (SN4000 series), or equivalent vendor 100GbE QSFP56 switches.
Cabling: QSFP56 100GbE DAC, AOC, or QSFP56 transceiver paired with MMF/SMF fiber.
Software: DOCA SDK, MLNX_OFED 5.x or newer, BlueField-2 BSP, Ubuntu / RHEL / CentOS / Rocky Linux on host.
Cooling: Server with adequate airflow for 100GbE DPU thermal envelope (consult NVIDIA BlueField-2 datasheet for per-port wattage).
