Single-port 400 Gb/s adapter for AI and HPC clusters

The NVIDIA ConnectX-7 MCX715105AS-WEAT is a PCIe 5.0 x16 network card with one QSFP112 port. It targets hyperscale clouds, scientific-computing sites and enterprise data centres that need RDMA over InfiniBand or Ethernet at up to 400 Gb/s.

Hardware-accelerated engines sustain line-rate

On-board acceleration offloads networking, storage and security processing from host CPUs. The adapter maintains 400 Gb/s Ethernet or NDR InfiniBand continuously, with auto-negotiation down to 10 Gb/s Ethernet or SDR InfiniBand, while operating between 0 °C and 55 °C.

Replaces dual-port 200 Gb/s

The jump is justified when workloads saturate 200 Gb/s links or require NDR200 and HDR100 InfiniBand modes that older cards cannot negotiate. Buyers who need a second physical port or a different form factor should select another model.

Questions about this item

How much heat does the ConnectX-7 generate when running at 400 Gb/s all day?

The card is rated for continuous operation from 0 °C to 55 °C ambient; active server airflow is required to keep it within that range.

What slot and cabling must already be in the server for this MCX715105AS-WEAT to work?

A PCIe 5.0 x16 slot (also compatible with Gen 4.0 and 3.0) plus one QSFP112 transceiver and matching InfiniBand or Ethernet cable.

Will this adapter negotiate down to 100 Gb/s Ethernet on my older switches?

Yes — the port auto-negotiates 400, 200, 100, 50, 25 and 10 Gb/s Ethernet as well as NDR, HDR, EDR and legacy InfiniBand rates.
