Dual-port 200GbE QSFP112 adapter

The NVIDIA ConnectX-7 VPI adapter card delivers dual-port QSFP112 connectivity at 200 Gb/s Ethernet or HDR InfiniBand. It installs in a PCIe 5.0 x16 slot and supports Multi-Host or Socket Direct configurations. Crypto and secure boot features are built in. The small form factor design fits dense server chassis.

Upgrade from single-port or lower-speed NICs

Replacing a single-port 100 GbE or 25 GbE card doubles port density and raises per-port throughput to 200 Gb/s. The jump is worthwhile when cluster interconnects or storage fabrics saturate existing links and the platform provides PCIe 5.0 x16 bandwidth. Older PCIe 3.0 slots will limit the adapter to 32 GT/s SERDES rates.

PCIe 5.0 x16 lane and thermal envelope

The card requires a full x16 electrical connection at Gen 5.0 to sustain 200 Gb/s per port; Gen 4.0 or 3.0 slots reduce available SERDES speed to 16 GT/s or 8 GT/s respectively. Operational temperature range is 0 to 55 °C with 10 to 85 % relative humidity. Non-operational limits extend to -40 °C and 70 °C at up to 90 % humidity.

Questions about this item

What PCIe slot size and bracket type does the MCX753436MC-HEAB require?

The card uses a PCIe 5.0 x16 slot and ships with a thumbscrew pull-tab bracket for tool-free mounting in a standard full-height bay.

How is the adapter installed, and what step is often missed?

Insert the card into a PCIe 5.0 x16 slot, secure the thumbscrew bracket, then attach QSFP112 cables or modules to both ports; the step often missed is connecting auxiliary power if the platform requires it.

What ongoing maintenance does the ConnectX-7 dual-port adapter need?

Keep the operating temperature between 0 and 55 °C and humidity at 10–85 % relative humidity; periodically reseat the QSFP112 modules and verify firmware is current.
