What This Is NOT

NOT EDR or HDR. FDR maximum (56Gb/s IB). For EDR (100Gb/s) see ConnectX-5 EDR; for HDR (200Gb/s) see ConnectX-6 HDR.
NOT Ethernet-only. VPI dual-protocol — IB FDR or Ethernet, port-selectable via mlxconfig.
NOT a standard NVIDIA retail card. Lenovo OEM firmware — verify support outside ThinkSystem servers before deploying.
NOT a 100GbE card. Max Ethernet 56GbE per port (not 100GbE).
NOT supplied with QSFP cables or transceivers — order separately.

Compatibility
Pairs with FDR InfiniBand fabrics (Mellanox SX6000-series / Switch-IB SB7700-series switches) and 40/56GbE Ethernet fabrics (Spectrum SN2000-series). Compatible with Mellanox MC2207 series passive copper QSFP DAC, MC2207310 active optical cables, and MC2210 QSFP+ AOCs at 40GbE. Host-side: PCIe 3.0 x8 slot, Lenovo ThinkSystem SR-series rack servers (SR630, SR650, SR850, etc.) for full firmware support. Driver support: MLNX_OFED (Linux) and WinOF-2 (Windows) — verify Lenovo firmware revision against OFED matrix before kernel upgrades.
