Description

NVIDIA Mellanox MBF2H516B-CENOT BlueField-2 P-Series SmartNIC, Dual-Port 100GbE QSFP56: This is a BlueField-2 P-Series Ethernet DPU adapter (NVIDIA P/N 900-9D205-0056-ST2) with two QSFP56 cages for 100Gb/s Ethernet. The card integrates an 8-core Arm SoC, 16GB DDR4 ECC on-card memory, and a PCIe Gen4 x16 host interface in an FHHL form factor. Crypto offload and Secure Boot are enabled on this SKU. This is not a passive NIC; it is a fully programmable Ethernet DPU. This is a refurbished unit.

Engineering Context

The MBF2H516B-CENOT pairs a ConnectX-6 Dx Ethernet controller with an 8-core Arm SoC running at up to 2.75 GHz. The 16GB DDR4 ECC at 3200 MT/s feeds the Arm subsystem. PCIe Gen4 x16 provides up to ~32GB/s peak host bandwidth at 16 GT/s per lane. Hardware crypto includes IPsec/TLS offload; Secure Boot ensures only signed firmware images can boot the DPU. This is the Ethernet-only P-Series variant of the BlueField-2 family — it does not support InfiniBand mode.

Deployment & Use Cases

Hyperscale cloud OVS data plane offload. Software-defined firewalling and microsegmentation. Bare-metal-as-a-service with DPU-isolated infrastructure traffic. NVMe-over-TCP target acceleration. Edge security gateways requiring Secure Boot for compliance. Tenant isolation in multi-tenant Ethernet fabrics.

Compatibility & Hard Constraints

Requires PCIe Gen4 x16 slot for full bandwidth (Gen3 x16 is functional but bandwidth-limited). QSFP56 cages accept QSFP56 100GbE DAC/AOC/optical transceivers per Mellanox firmware compatibility lists. Requires DOCA framework or MLNX_OFED with BlueField support. P-Series is Ethernet-only — does not support InfiniBand mode (use M-Series E-Series for VPI). Secure Boot requires firmware images signed for this card; unsigned firmware will be rejected. Power draw is higher than a passive 100GbE NIC; verify slot power budget.
