Description

NVIDIA Mellanox MBF2M322A-AENET BlueField-2 E-Series SmartNIC DPU, Dual 25GbE SFP56: This is a programmable BlueField-2 Data Processing Unit (DPU) with two 25GbE SFP56 network ports for infrastructure offload and acceleration in enterprise data centers. The card pairs an 8-core Arm SoC with on-board memory and a PCIe Gen4 host interface; it is not a standard NIC. This variant has on-card crypto disabled. This is a refurbished unit.

Engineering Context

The MBF2M322A-AENET integrates an 8-core BlueField-2 Arm SoC at up to 2.0 GHz with 16 GB of on-board DDR4 memory, allowing it to host a software stack for network, storage, and security functions independent of the host CPU. The PCIe Gen4 x16 host interface (operable as x8) supplies up to 32 GT/s per lane. A dedicated 1GbE out-of-band (OOB) management port enables provisioning of the DPU separately from the data plane. Crypto offload is disabled in this SKU, simplifying export and compliance handling.

Deployment & Use Cases

Bare-metal cloud and managed-hosting infrastructure where the DPU runs the hypervisor data path and isolates tenant workloads. NVMe-over-Fabrics initiator and target offload, storage virtualization, and software-defined networking with OVS hardware offload and connection tracking. Cloud-native security functions, micro-segmentation, and stateful firewalling in regions where on-card crypto is not required.

Compatibility & Constraints

Requires a host platform with a free PCIe Gen4 (or Gen3 fallback) x16 or x8 slot and BIOS/UEFI support for large BAR / above-4G decoding. Supported on the NVIDIA DOCA software framework on standard x86_64 Linux distributions; verify kernel and OS levels against the DOCA release you intend to run. Optical and DAC cables must be 25GbE-rated and SFP56-compatible. Because crypto is disabled on this SKU, it is not suitable for workloads that require on-card IPsec or TLS encryption acceleration. Some BlueField-2 features (such as NVMe SNAP and RegEx) depend on licensing and host OS support — confirm with NVIDIA documentation.

Frequently Asked Questions (FAQ)

Q. What is the MBF2M322A-AENET?
The MBF2M322A-AENET is a BlueField-2 DPU with dual SFP56 ports at up to 25GbE, crypto disabled.

Q. Can it run as an ordinary NIC?
Yes. BlueField-2 supports a NIC-compatibility mode set in firmware.

Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MBF2M322A-AENET before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, before dispatch from EU stock.
