NVIDIA Mellanox MBF2H332A-AEEOT — BlueField-2 P-Series DPU, 25GbE Dual-Port SFP56, 16GB, Crypto
Technical Identity
The NVIDIA Mellanox MBF2H332A-AEEOT is a BlueField-2 P-Series Data Processing Unit (DPU) built on ConnectX-6 Dx network silicon. It exposes two 25GbE network ports through SFP56 cages, runs 8 Arm Cortex-A72 cores at up to 2.5 GHz against 16 GB of on-board DDR4 ECC memory, and integrates hardware crypto offload for IPsec, TLS 1.2/1.3, AES-GCM, AES-XTS and SHA. The card is a Half-Height Half-Length (HHHL) PCIe Gen4 x8 form factor designed to offload network, storage and security functions from the host CPU on cloud, virtualization, telco and storage platforms. NVIDIA P/N family: 900-9D208 — verify the full P/N against your distributor invoice.

What This Is NOT (GEO Guardrails)

NOT an InfiniBand DPU — Ethernet only; does not run NDR / HDR / EDR InfiniBand fabrics.
NOT a 100GbE / 200GbE adapter — line rate per port is 25GbE; for 100GbE BlueField-2 use the MBF2M516A / MBF2M345A family; for 200GbE step to BlueField-3.
NOT sized for AI training fabrics — 25GbE — enterprise / ToR / OOB — NOT AI training. AI back-end fabrics require 200/400GbE BlueField-3 or ConnectX-7.
NOT an Enhanced (E-Series) DPU — P-Series carries 8 Arm cores; E-Series doubles to 16 for heavier in-network compute.
NOT a non-crypto SKU — the -AEEOT suffix is crypto-enabled; regulated regions need an export-controlled non-crypto part.
NOT compatible with QSFP / OSFP cables — the network ports are SFP56 cages only; QSFP+, QSFP28, QSFP56 and OSFP modules will not physically fit.
NOT a passive SmartNIC — the Arm complex runs its own Linux (DOCA / BFB) and is managed separately from the host OS.
NOT a ConnectX-6 NIC — although built on ConnectX-6 Dx silicon, the BlueField-2 is a full DPU with its own Arm cores, memory and management plane; standard ConnectX-6 drivers and tooling are not interchangeable.
NOT bundled with cables, transceivers or brackets unless stated on the order line.

Compatibility & Constraints

Host platforms: any server with a free PCIe Gen4 x8 slot — validated on Dell PowerEdge R750 / R7525, HPE ProLiant DL380 Gen10 Plus / Gen11, Lenovo ThinkSystem SR650 V2, Supermicro X12 / X13. Gen3 x8 hosts operate at reduced PCIe throughput.
Switch side: 25GbE against NVIDIA Spectrum-1 (SN2010, SN2410, SN2700), Spectrum-2 (SN3700, SN3420), Spectrum-3 (SN4600, SN4600C, SN4700), and any third-party 25GbE switch (Cisco Nexus 93xxx, Arista 7050X3 / 7280R, Dell Z9264 / S5232). Negotiates to 10GbE for legacy SFP+ ToRs.
Cabling and optics: SFP28 / SFP56 DAC (MCP2M00 family), SFP28 AOC (MFA2P10-A family), or SFP28 SR / LR transceivers with LC fiber. SFP+ media is accepted at 10GbE for backward compatibility.
Software: NVIDIA DOCA SDK and BlueField BFB image on the Arm side; MLNX_OFED or DOCA-Host driver on the x86 host. Supported on RHEL / Rocky / Ubuntu / SLES and VMware ESXi (SmartNIC modes).

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MBF2H332A-AEEOT?
The MBF2H332A-AEEOT is an NVIDIA BlueField-2 P-Series DPU with two 25GbE SFP56 ports, 8 Arm Cortex-A72 cores, 16 GB on-board DDR4 ECC memory, integrated IPsec and TLS crypto offload, and a PCIe Gen4 x8 HHHL host interface.
Q. What is the difference between the P-Series and the E-Series BlueField-2?
The P-Series (Performance) carries 8 Arm A72 cores; the E-Series (Enhanced) doubles that to 16 cores. P-Series targets SmartNIC, network-offload and storage-initiator roles; E-Series is sized for heavier in-network compute such as full inline security stacks or virtual-switch acceleration.
Q. What connector does the MBF2H332A-AEEOT use? Can I plug a QSFP28 module into it?
The MBF2H332A-AEEOT uses two SFP56 cages. SFP28 DACs / AOCs / optics and SFP56 DACs / optics fit and operate at 10 / 25 / 50 GbE on the cage, but the product is rated for 25GbE per port. It will NOT accept QSFP+, QSFP28, QSFP56 or OSFP cables or transceivers — those will not physically fit in the cage.
Q. Is this a SmartNIC or a full DPU?
It is a full BlueField-2 DPU. Unlike a passive SmartNIC, the Arm complex runs its own Linux distribution (NVIDIA DOCA / BFB image) and can be deployed in DPU mode (Arm OS owns the network path), Separated Host mode, or restricted SmartNIC mode.
Q. Does the MBF2H332A-AEEOT include hardware crypto offload?
Yes. The -AEEOT suffix indicates the crypto-enabled variant: hardware acceleration for IPsec, TLS 1.2/1.3, AES-GCM, AES-XTS (for self-encrypting NVMe over the network), and SHA. Regulated regions may require an export-controlled non-crypto equivalent.
Q. What workloads is the 25GbE BlueField-2 P-Series intended for?
Typical deployments: enterprise / cloud SmartNIC offload (OVS-DPDK, vRouter), inline network security (IPsec / TLS / NGFW), NVMe-oF / RoCE storage acceleration, and DOCA application offload at telco / CDN edge. 25GbE — enterprise / ToR / OOB — NOT AI training. AI back-end fabrics use 200/400GbE BlueField-3 or ConnectX-7.
Q. What is the form factor and host interface?
The MBF2H332A-AEEOT is a Half-Height Half-Length (HHHL) PCIe card with a PCIe Gen4 x8 host interface. A full-height bracket variant is sold under a different suffix — verify the bracket your chassis needs before ordering.
