NVIDIA Mellanox MBF1M332A-ASNAT BlueField-1 SmartNIC DPU, Dual-Port 25GbE SFP28 with Crypto: This is a first-generation BlueField Data Processing Unit (DPU) PCIe adapter combining a Mellanox ConnectX-5 NIC pipeline with onboard ARM compute. NVIDIA part number 900-9D110-0053-SQ0. This is a half-height, half-length (HHHL) board with a tall bracket, dual SFP28 ports, and integrated cryptographic acceleration. This is a refurbished unit.
Engineering Context
BlueField-1 integrates a Mellanox ConnectX-5 NIC engine with an ARM-based system-on-chip and DDR4 memory directly on the adapter, so packet processing, storage offload, and security functions can run on the DPU rather than the host CPU. The MBF1M332A-ASNAT exposes two SFP28 cages at up to 25Gb/s each and a PCIe Gen3.0 / Gen4.0 host interface that can be configured as x16 or x8. The 'Crypto Enabled' designation means the IPsec and TLS offload engines are populated, which in turn classifies the part under U.S. ECCN 5A002.a.
Deployment & Use Cases
Targeted at NFV / vRAN data planes (DPDK, OVS-DPDK), bare-metal cloud infrastructure (BlueField as the isolation point between tenant and provider), NVMe-over-Fabrics targets and initiators with TLS / IPsec termination on the DPU, software-defined storage front-ends, and security-focused edge appliances that need line-rate IPsec at 2x25GbE without burning host cores.
Technical Specifications
Series: NVIDIA BlueField-1 SmartNIC DPU
NIC engine: Mellanox ConnectX-5 pipeline
Network ports: 2x SFP28 at 25Gb/s Ethernet (also negotiates 10GbE)
Host interface: PCIe Gen3.0 / Gen4.0 x16 (configurable as x8)
Cryptographic offload: Enabled (IPsec, TLS) - ECCN 5A002.a applies
RDMA: RoCEv1 / RoCEv2 supported by the ConnectX-5 engine
Form factor: HHHL (half-height, half-length)
Bracket: Tall
Manufacturer: NVIDIA Mellanox Technologies Ltd
NVIDIA P/N: 900-9D110-0053-SQ0
Compatibility & Constraints
Pairs with NVIDIA Mellanox SFP28 25GbE DACs (MCP2M00 series), AOCs (MFA2P10 series), and 25GbE optical transceivers (MMA2P00 series). Validate host server PCIe slot wiring; an x16 mechanical slot wired x8 will operate at x8 only. The crypto-enabled variant (suffix '-ASNAT') is subject to U.S. export control under ECCN 5A002.a; buyers are responsible for export compliance. This is a BlueField-1 product, not BlueField-2 or BlueField-3 - DOCA software stack support is limited to the BlueField-1 baseline. This card is not a passive NIC; it boots its own ARM Linux and requires DPU-aware deployment workflow.
