NVIDIA Mellanox MBF2M322A-AEEOT BlueField-2 E-Series Data Processing Unit (DPU), 25GbE Dual-Port SFP56: This is a BlueField-2 E-Series DPU — a PCIe adapter that pairs an integrated NVIDIA ConnectX-6 Dx NIC with an 8-core 64-bit Arm SoC, so networking, security, and storage services can be offloaded from the host CPU. NVIDIA part number 900-9D206-0063-ST4. This IS a Full-Height Half-Length (FHHL) PCIe Gen 3.0/4.0 x8 dual-port 25GbE DPU with 8 GB of on-board DDR4 ECC memory and a dedicated 1GbE RJ-45 out-of-band management port. This IS NOT a plain ConnectX-6 Dx NIC, a SmartNIC without ARM cores, or a single-port adapter. Condition: Refurbished, fully tested.
Engineering context. The on-board BlueField-2 SoC combines eight Armv8 A72 cores with the ConnectX-6 Dx network ASIC and 8 GB of DDR4 ECC memory, allowing the card to run an embedded Linux distribution independently of the host operating system. The two SFP56 cages each carry one 25GbE Ethernet port. The PCIe Gen 3.0/4.0 x8 host interface delivers up to 15.75 GB/s of raw I/O bandwidth to the server. Hardware crypto acceleration is enabled on this SKU. E-Series boards integrate an on-board management controller for lights-out provisioning of the embedded ARM subsystem.
Deployment and use cases. Typical workloads include bare-metal cloud infrastructure with tenant isolation and Open vSwitch offload (OVS-DOCA), NVMe over Fabrics (NVMe-oF/TCP and NVMe-oF/RoCE) target and initiator services that run on the embedded Arm cores rather than the host CPU, software-defined firewall and DDoS scrubbing using DOCA App Shield and DOCA Flow, and disaggregated control-plane services in NFV deployments. The DPU is also used as a hardware root of trust for zero-trust data-center architectures.
Technical specifications.
MPN: MBF2M322A-AEEOT
NVIDIA P/N: 900-9D206-0063-ST4
DPU SoC: NVIDIA BlueField-2 with integrated ConnectX-6 Dx
ARM cores: 8 × Armv8 A72
Network ports: 2 × SFP56, 25GbE Ethernet
Host interface: PCIe Gen 3.0/4.0 x8
On-board memory: 8 GB DDR4 ECC
Out-of-band management: 1 × 1GbE RJ-45
Crypto offload: Enabled
Form factor: Full-Height Half-Length (FHHL)
Cooling: Passive heatsink (server-supplied airflow)
Condition: Refurbished, individually tested
Compatibility and constraints. Software stack: NVIDIA DOCA SDK, MLNX_OFED, and the BlueField Board Support Package; the host can run Ubuntu, RHEL, SLES, or other supported Linux distributions, and the embedded Arm subsystem ships with Ubuntu. Power and slot: requires a PCIe Gen 3.0/4.0 x8 slot in a server able to deliver adapter power per PCIe CEM specification — verify on the server vendor's QVL. Thermal: passive heatsink, requires managed front-to-back airflow; not suitable for workstation chassis without server-grade cooling. Hardware IPsec and TLS offload is supported on this SKU through DOCA. E-Series boards have an on-board BMC; if your environment provisions BlueField-2 strictly through host-side tooling, the matching P-Series part may be a better fit. Cabling: NVIDIA Mellanox SFP56 DACs and AOCs from the matching speed family are recommended; verify against the BlueField-2 Adapter Product Release Guide.
