NVIDIA Mellanox MBF2M516C-EECOT BlueField-2 SmartNIC 100GbE 2xQSFP56 PCIe4

NVIDIA Mellanox MBF2M516C-EECOT BlueField-2 E-Series SmartNIC DPU: This is a dual-port QSFP56 100GbE / EDR / HDR100 data processing unit (DPU) built on the BlueField-2 platform with an integrated 8-core Arm SoC, 16GB of DDR4 ECC memory, and PCIe Gen 4.0 x16 host interface. The card includes a hardware crypto/secure boot block and 1GbE out-of-band BMC management. Form factor is full-height half-length (FHHL). This is a refurbished unit (NVIDIA P/N: 900-9D208-0086-ST4).

Engineering Context

The BlueField-2 architecture combines a ConnectX-6 Dx-class network adapter with an on-die Arm SoC, allowing the DPU to terminate networking, security, and storage services on the card itself. The 8-core Arm SoC runs at 2.0 GHz and runs an independent Linux OS image (DOCA / BlueField OS). 16GB DDR4 ECC supports the SoC and DPU services. Dual QSFP56 ports support 100GbE Ethernet, EDR InfiniBand (100Gb/s), or HDR100 (100Gb/s InfiniBand) — the EECOT SKU is part of the E-Series, oriented to enterprise and storage offload deployments. The integrated crypto block and secure boot capability suit zero-trust and tenant-isolation use cases. PCIe Gen 4.0 x16 to the host provides full bandwidth headroom for two 100GbE ports.

Deployment & Use Cases

Bare-metal cloud tenant isolation and infrastructure offload. NVMe-over-Fabrics target / initiator offload from host CPU. Hardware-accelerated firewall, IDS, or DDoS scrubbing in line with the wire. Storage virtualization and software-defined storage acceleration. Secure boot / root-of-trust offload for confidential computing. SDN dataplane termination on the NIC.

Compatibility & Hard Constraints

Requires a PCIe Gen 4.0 x16 host slot for full bandwidth; will negotiate down to PCIe 3.0 x16 with bandwidth penalty. FHHL form factor requires a full-height server slot. The BlueField-2 SoC must be initialized and provisioned with a BlueField OS / DOCA image — this is not a transparent NIC; running it as a stock NIC requires explicit configuration. Crypto features depend on enablement of the BlueField crypto stack and licensed software where applicable. The QSFP56 ports support 100GbE Ethernet, EDR InfiniBand, or HDR100; mode is set per port at the host/SoC. Optical and DAC interconnect must match the chosen protocol. EECOT is the E-Series Crypto-Enabled SKU — distinct from P-Series (BMC differences) and from non-crypto BlueField-2 variants.
