NVIDIA Mellanox MBF2M922A-AEEAB BlueField-2 DPU, Dual 25GbE SFP56, OCP 3.0 SFF, Crypto-Enabled: This is a BlueField-2 Data Processing Unit (DPU) — a SmartNIC with an onboard 8-core Arm Cortex-A72 SoC at 2.0 GHz, 16GB DDR4 memory, integrated cryptographic accelerators, and dual SFP56 ports running at 25GbE per port. It is delivered in the OCP 3.0 Small Form Factor. NVIDIA P/N: 900-9D204-0063-MB0. This is a DPU, not a passive NIC and not a discrete CPU module. This is a refurbished unit.
Engineering Context
BlueField-2 combines a ConnectX-6 Dx network controller with an embedded 8-core Arm SoC, allowing infrastructure functions — virtualization data path, software-defined storage, security, and networking control plane — to run on the DPU itself rather than on host CPU cores. The card carries 16GB of DDR4 onboard memory dedicated to the Arm complex. Cryptographic acceleration covers AES-GCM, AES-XTS, SHA-2, and IPsec inline offload. The host interface negotiates PCIe Gen3 x16 or Gen4 x16. Dual SFP56 ports run 25GbE NRZ (the 56 in SFP56 denotes the cage class, not link speed for this SKU).
Deployment & Use Cases
Bare-metal cloud isolation (NVIDIA DOCA-based BlueField OS owns the data path while the host x86 runs untrusted tenants). NVMe-oF target with onboard storage acceleration. IPsec / TLS inline encryption gateway. Software-defined firewall and load balancer at line rate. VMware vSphere Distributed Services Engine (project Monterey) DPU host. Telco / 5G UPF acceleration. Hyperconverged platforms requiring infrastructure offload from the host CPU.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MBF2M922A-AEEAB (NVIDIA P/N 900-9D204-0063-MB0)
Family: BlueField-2 DPU
Form Factor: OCP 3.0 Small Form Factor (SFF)
Ports: Dual SFP56
Data Rate: 25GbE per port
SoC: 8-core Arm Cortex-A72 @ 2.0 GHz
Onboard Memory: 16GB DDR4
Crypto: Enabled — AES-GCM, AES-XTS, SHA-2, IPsec inline
Host Interface: PCIe Gen3 x16 / Gen4 x16
Software: NVIDIA DOCA, BlueField OS (Ubuntu-based)
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Constraints
Requires a server with an OCP 3.0 SFF cage exposing PCIe Gen3 x16 or Gen4 x16 host. The DPU SoC boots its own OS independent of the host; integration requires DOCA SDK or BlueField OS familiarity. Compatible with NVIDIA Spectrum 25GbE switches and any standards-based 25GbE Ethernet fabric. SFP56 cages accept 25GbE SFP28 transceivers and DACs (auto-negotiation handles the speed downshift). Not a standard PCIe card — it will not seat in a regular slot. Not a 100GbE DPU — that variant is the MBF2M516A series. Not compatible with OCP 2.0 chassis.
