NVIDIA Mellanox MBF2H516B-EEEOT BlueField-2 P-Series SmartNIC, Dual-Port 100GbE QSFP56: This is a BlueField-2 P-Series programmable DPU adapter (NVIDIA P/N 900-9D205-0066-ST0) with two QSFP56 cages for 100Gb/s Ethernet. The card integrates an 8-core Arm SoC, 16GB DDR4 ECC on-card memory, 128GB eMMC local storage, and a PCIe Gen4 x16 host interface in an FHHL form factor. Crypto offload is enabled on this SKU. This is not a passive NIC; it is a fully programmable DPU. This is a refurbished unit.
Engineering Context
The MBF2H516B-EEEOT pairs a ConnectX-6 Dx network controller with an 8-core Arm SoC running at up to 2.75 GHz. The 16GB DDR4 ECC at 3200 MT/s feeds the Arm subsystem; the 128GB eMMC provides bootable local storage for the DPU operating system (Ubuntu via DOCA). PCIe Gen4 x16 delivers up to ~32GB/s peak host bandwidth, sufficient for line-rate 200Gb/s aggregate I/O. Crypto offload includes IPsec and TLS acceleration on this CEN/EEN class SKU.
Deployment & Use Cases
Hyperscale cloud data plane offload (OVS, VXLAN). NVMe-over-Fabrics target and initiator acceleration. Software-defined firewalling and east-west microsegmentation. Bare-metal-as-a-service infrastructure where the DPU isolates tenant from infrastructure. AI cluster fabric offload for RoCE traffic management.
Technical Specifications

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Requires PCIe Gen4 x16 slot for full bandwidth (Gen3 x16 is functional but bandwidth-limited). QSFP56 cages accept QSFP56 100GbE DAC/AOC/optical transceivers per Mellanox firmware compatibility lists. Requires DOCA framework or MLNX_OFED with BlueField support. The 128GB eMMC is for DPU OS, not host data storage. Not a drop-in ConnectX NIC — DPU runtime is mandatory. Power draw is higher than a passive 100GbE NIC; verify PCIe slot power budget.
