NVIDIA Mellanox MBF2H332A-AEEOT BlueField-2 DPU, Dual 25GbE SFP56, PCIe Gen3/Gen4 x8: This is a BlueField-2 P-Series Data Processing Unit (DPU) with two SFP56 ports for 25Gb/s Ethernet and a PCIe Gen3/Gen4 x8 host interface. The card pairs ConnectX-6 Dx-class network silicon with an Arm-based compute complex and a 1GbE out-of-band management port for headless DPU control. This is a SmartNIC/DPU plug-in card, not a transceiver, switch, or simple host NIC. NVIDIA P/N 900-9D206-0063-ST2. This is a refurbished unit.
Engineering Context
The MBF2H332A-AEEOT brings DPU offload capability to 25GbE deployments where dual 100GbE is not required and PCIe x8 slot density matters. Each SFP56 port runs a single lane at 25Gb/s NRZ. PCIe Gen4 x8 at 16GT/s per lane provides up to 16GB/s of host bandwidth, more than enough for two 25GbE ports plus DPU offload. Crypto is enabled for hardware-accelerated IPsec, TLS, and storage encryption. The 1GbE BMC-style out-of-band management port allows separate provisioning and telemetry independent of the data plane. On-board 16GB DDR memory supports DOCA workloads on the embedded Arm domain.
Deployment & Use Cases
Edge cloud and telco compute nodes where 25GbE is the dominant access speed. Software-defined networking offload for VMware NSX, OVN, and Open vSwitch in 25G fabrics. NVMe-over-Fabrics target nodes connected via 25G storage networks. Distributed firewall and microsegmentation in cost-sensitive deployments. AI inference servers where DPU-resident security is required without consuming x86 cores.

Compatibility & Constraints
Requires a server PCIe Gen3 or Gen4 x8 mechanical and electrical slot. Compatible with NVIDIA DOCA SDK and BlueField OS releases that target BlueField-2. Compatible with SFP56 25GbE optics and DACs; SFP28 and SFP+ optics work where the host port and optic explicitly negotiate the lower data rate. The AEEOT suffix has crypto enabled and is not interchangeable with non-crypto suffixes in regulated environments. Not a 100GbE-capable card and not a stand-alone bridge — the SoC requires PCIe attachment to a host system for control plane initialization.
