NVIDIA Mellanox MBF2M516A-EEEOT BlueField-2 E-Series DPU, Dual-Port 100GbE / EDR InfiniBand QSFP56: This is a BlueField-2 E-Series VPI DPU adapter (NVIDIA P/N 900-9D219-0066-ST0) with two QSFP56 cages supporting either 100Gb/s Ethernet or EDR InfiniBand per port. The card integrates an 8-core Arm SoC, 16GB DDR4 ECC, 64GB eMMC local storage, and a PCIe Gen4 x16 host interface in an FHHL form factor. Crypto offload is enabled. This is not a passive NIC; it is a programmable VPI DPU. This is a refurbished unit.
Engineering Context
The MBF2M516A-EEEOT pairs a ConnectX-6 Dx VPI controller with an 8-core Arm SoC. The VPI capability allows each QSFP56 port to be independently configured as 100GbE or EDR (100Gb/s) InfiniBand. The 16GB DDR4 ECC operates at 3200 MT/s; the 64GB eMMC hosts the DPU operating system. PCIe Gen4 x16 provides up to ~32GB/s peak host bandwidth at 16 GT/s per lane. The E-Series designation distinguishes this from the P-Series (Ethernet-only) variants.
Deployment & Use Cases
HPC clusters where InfiniBand EDR fabric coexists with Ethernet management. AI training fabrics with RDMA over both protocols. Software-defined storage gateways bridging IB and Ethernet. NVMe-over-Fabrics targets where transport flexibility is required. Multi-tenant clouds where the DPU isolates infrastructure traffic from tenant traffic.
Technical Specifications

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Requires PCIe Gen4 x16 slot for full bandwidth. QSFP56 cages accept compatible 100GbE DAC/AOC/optical or EDR InfiniBand cables per Mellanox firmware compatibility lists. Each port can be configured for Ethernet or InfiniBand independently via firmware/driver, but mode changes require a port reset. Requires DOCA framework or MLNX_OFED with BlueField support. The 64GB eMMC is for the DPU OS, not host storage. Not a drop-in ConnectX-6 NIC; DPU runtime is mandatory.
