What This Is NOT

NOT a standard 100GbE NIC. This is a full DPU with 8-core Arm subsystem, 32GB DDR4, and BMC — not a passthrough adapter like ConnectX-6 Dx MCX623106AN-CDAT.
NOT SFP56 / SFP28. Both ports are QSFP56 (100GbE). For 25GbE SFP56 DPU, see MBF2H532C-AECOT.
NOT InfiniBand. Ethernet-only. For VPI/IB BlueField-2, see MBF2M-series E-Series DPUs.
NOT Crypto Disabled. Crypto Enabled — verify export compliance.
NOT supplied with QSFP56 transceivers, AOC/DAC cables, or rail-kit accessories.

Compatibility & Constraints

Host interface: PCIe Gen4 x16 (backwards compatible Gen3 x16 at reduced bandwidth).
Network pairing: 100GbE QSFP56-capable switches — NVIDIA Spectrum-2 (SN3700), Spectrum-3 (SN4600C), or equivalent Ethernet ToR. Compatible 100GbE QSFP56 cables include MCP1650-H, MFA1A00-C, and MMA1T00-HS transceivers.
Software stack: NVIDIA DOCA SDK, MLNX_OFED, BlueField-2 BSP. BMC managed via IPMI/Redfish.
Pre-deployment: Confirm PCIe x16 slot wattage (~75W typical), BIOS PCIe settings, firmware level, and DOCA/BSP version compatibility with target OS.
