Dual-port 200GbE NDR200 adapter for servers

This NVIDIA ConnectX-7 adapter installs in a PCI Express 5.0 x16 slot and presents two QSFP112 ports. It operates at 200, 100, 50, 25 or 10 Gb/s in Ethernet mode and supports InfiniBand NDR200, HDR, HDR100, EDR, FDR and SDR speeds. The half-height half-length card fits standard server chassis and targets high-density compute clusters. Crypto acceleration is disabled on this part number.

Thermals, noise and power draw

Typical power consumption with passive cables in a Gen 5.0 x16 slot is 24.9 W from the 12 V and 3.3 VAUX rails, with a maximum current of 100 mA. The plug-in card uses no onboard fan, so acoustic output depends entirely on the host system airflow. Auxiliary cabline harnesses route signals to a secondary bracket without adding active cooling components.

Single-slot x16 lane requirement

The adapter requires a full x16 electrical connection running at Gen 5.0 or Gen 4.0 SERDES rates of 32 or 16 GT/s per lane. A physical x16 slot wired for fewer lanes will limit throughput. Buyers whose platforms provide only x8 electrical links should verify bandwidth needs before selecting this card.

Questions about this item

How do I install the MCX755106AS-HEAT with its auxiliary PCIe connection card and the two Cabline CA-II Plus harnesses?

Insert the half-height, half-length adapter into a PCIe 5.0 x16 slot, mount the auxiliary card measuring 5.09 in by 2.32 in, then connect the white and black Cabline CA-II Plus harnesses between the two boards.

What maintenance or replacement will the dual-port QSFP112 adapter need over time?

The optical QSFP112 transceivers and fiber patch cables are the only field-replaceable parts; the card itself has no fans or moving components to service.

At what sustained load does the 24.9 W typical power draw become the limiting factor?

Continuous 200 Gb/s traffic on both ports at PCIe Gen 5.0 x16 keeps the adapter at its 24.9 W typical power, so chassis cooling must handle that steady thermal load.
