NVIDIA Mellanox® MBF2H532C-AECOT — BlueField-2 P-Series DPU, 25GbE Dual SFP56, 32GB
Technical Identity
The NVIDIA Mellanox® MBF2H532C-AECOT is a BlueField-2 P-Series Data Processing Unit (DPU) combining an 8-core Arm Cortex-A72 SoC, ConnectX-6 Dx network engine, and 32GB on-board DDR4 memory on a single PCIe Gen4 x8 FHHL card with Tall Bracket. The card exposes two SFP56 ports operating at 25GbE per port and includes an integrated Board Management Controller (BMC) with a dedicated 1GbE out-of-band (OOB) management port. This OPN is supplied with Secure Boot Enabled and Crypto Enabled, providing hardware-accelerated IPsec / TLS, NVMe over Fabrics (NVMe-oF), RoCE v2, Open vSwitch (OVS) offload, and the NVIDIA DOCA application framework. Condition: Refurbished Grade A.

What This Is NOT

NOT a standard NIC. The MBF2H532C-AECOT is a full DPU with on-board Arm cores, DDR4, and BMC — it runs its own Linux OS (BFB) independently of the host. A passive NIC (e.g. ConnectX-6 Dx MCX623106AN-CDAT) does not provide DPU offload.
NOT 100GbE or 200GbE. This OPN is 25GbE per port. For 100GbE see MBF2H516C-CECOT; for 200GbE see MBF2H536C-CECOT.
NOT Crypto Disabled. This part has Crypto Enabled — export compliance must be verified for the destination country before purchase.
NOT an E-Series (Enhanced) DPU. This is the P-Series (Performance) tier — E-Series variants add a dedicated DDR4 channel for the Arm subsystem.
NOT supplied with SFP28 / SFP56 transceivers, DAC / AOC cables, or low-profile bracket. These ship separately.

Compatibility & Constraints

Host slot: PCIe Gen4 x8 mechanical / electrical recommended (Gen3 x8 functional with reduced host bandwidth).
Switch pairing: Pairs with any 25GbE Ethernet switch supporting SFP28 optics or DACs — e.g. NVIDIA Spectrum SN2010 / SN2100 / SN2410, Spectrum-2 SN3420 / SN3700C, or third-party 25GbE leaf/spine switches.
Cabling: Use Mellanox / NVIDIA 25GbE SFP28 DACs (MCP2M00-A0xxxx series), AOCs (MFA2P10-A0xxx), or SFP28 SR / LR optics (MMA2P00-AS / MMA2L20-AR).
Software stack: Requires DOCA SDK 1.x or later, BlueField-2 BSP, and MLNX_OFED driver matched to the BSP version. The host OS sees a standard ConnectX-6 Dx NIC by default; DPU functionality is enabled by booting the BlueField Arm cores into the BFB image.
Export: Crypto Enabled — confirm ECCN classification and destination compliance before ordering.
Cooling: Active server chassis airflow required — this is a passive-heatsink card and depends on chassis fan curve.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MBF2H532C-AECOT?
A BlueField-2 P-Series DPU with dual 25GbE SFP56 ports, 8 Arm Cortex-A72 cores, 32GB DDR4, PCIe Gen4 x8, integrated BMC, Secure Boot Enabled, Crypto Enabled, FHHL Tall Bracket form factor.
Q. How is a BlueField-2 DPU different from a ConnectX-6 Dx NIC?
The DPU adds an 8-core Arm SoC, dedicated DDR4 memory, and a BMC on the same card. It runs its own Linux OS (BFB) and can execute control-plane, security, storage, and networking offload independently of the host CPU. A ConnectX-6 Dx NIC provides packet processing offload but no programmable Arm subsystem.
Q. Is MBF2H532C-AECOT Crypto Enabled?
Yes. This OPN ships with Crypto Enabled, supporting IPsec and TLS hardware offload. Verify export compliance for your destination country before ordering.
Q. What hardware offloads does MBF2H532C-AECOT support?
RoCE v2, NVMe over Fabrics (NVMe-oF), IPsec / TLS inline crypto, Open vSwitch (OVS) offload, Connection Tracking, VXLAN / GENEVE encap-decap, T10-DIF data integrity, and the full NVIDIA DOCA application framework.
Q. Which switches and cables pair with the MBF2H532C-AECOT?
Any 25GbE Ethernet switch with SFP28 ports — NVIDIA Spectrum SN2010 / SN2100 / SN2410, Spectrum-2 SN3420, or third-party 25GbE leaves. Use 25GbE SFP28 DACs (e.g. MCP2M00-A001 / -A002 / -A003), AOCs (MFA2P10-A005 etc.), or SFP28 SR / LR optics (MMA2P00-AS / MMA2L20-AR).
Q. What is the difference between the NEW and Refurbished version?
Identical hardware specification, firmware, and software support. Refurbished Grade A units are bench-tested, EEPROM-verified, BMC-checked, and cosmetically inspected — same functional capability as new at a reduced price point.
Q. What condition does T.E.S IT-SOLUTIONS supply?
Refurbished Grade A — EEPROM-verified, BMC-checked, cosmetically inspected, shipped from EU stock in professional anti-static packaging.
