Dual QSFP56 200 Gb/s adapter for data-centre

The NVIDIA ConnectX-6 MCX653106A-HDAT is a dual-port VPI network card built for high-performance computing and storage fabrics. It delivers 200 Gb/s per port over InfiniBand HDR or 200 GbE Ethernet with sub-600 ns latency and 215 million messages per second. The card targets administrators scaling HPC, AI training or parallel file-system clusters.

PCIe 3.0 or 4.0 x16 slot with tall bracket

Installation requires a full-height PCIe 3.0 or 4.0 x16 slot and the supplied tall bracket. Each QSFP56 cage accepts copper or optical transceivers, freeing the builder from proprietary cabling. The adapter operates from 0 °C to 55 °C at 10 % to 85 % relative humidity, so standard server airflow is sufficient.

Replaces single-port or EDR-era cards

Upgrading from a single-port HCA or an EDR-generation adapter doubles port density and moves the fabric to 200 Gb/s without changing the PCIe footprint. The jump is worth it when message-rate bottlenecks appear or when storage nodes need 200 GbE line rate. Buyers staying at 100 Gb/s or below will not use the headroom.

Questions about this item

What is the maximum data rate per lane that the ConnectX-6 card can auto-negotiate for InfiniBand HDR?

The card auto-negotiates up to 50 Gb/s per lane for InfiniBand HDR across its dual QSFP56 ports.

What operational temperature range must the chassis airflow maintain for this adapter?

The adapter is rated for continuous operation between 0 and 55 degrees Celsius.

Which PCIe slot generation and width does the MCX653106A-HDAT require for full 200 Gb/s throughput?

It requires a PCIe 3.0 or 4.0 x16 slot to deliver the full 200 Gb/s per port bandwidth.
