  • QSFP56 connectors support HDR100 InfiniBand and Ethernet protocols

Dual-Port 100GbE Adapter Card

The Mellanox ConnectX-6 VPI MCX653106AECATSP is a dual-port QSFP56 expansion card delivering 100GbE and HDR100 InfiniBand connectivity over a PCIe 3.0/4.0 x16 interface. It targets data-centre operators and HPC clusters that require high-throughput, low-latency networking for compute, storage and machine-learning workloads.

Suited for high-density 100GbE deployments

This card suits builders populating racks with dual-port 100GbE links using QSFP56 optics or direct-attach cables. It is not for buyers who need single-port connectivity or lower-speed links, nor for systems limited to PCIe x8 electrical slots or shorter brackets.

PCIe 3.0/4.0 x16 electrical requirement

The single specification that decides fitment is the PCIe 3.0/4.0 x16 electrical interface; the host slot must provide sixteen lanes at Gen 3 or Gen 4 to achieve rated throughput. Verify slot length and bracket height before purchase.

Questions about this item

What PCIe slot generation and width does the MCX653106AECATSP require?

The card uses a PCIe 3.0 or 4.0 x16 slot for full bandwidth.

Can the dual QSFP56 ports run at 100 GbE with older InfiniBand cabling?

Each port supports 100 GbE and HDR100 EDR InfiniBand over QSFP56 cables or transceivers.

How can I verify the adapter is delivering the rated 200 Gb/s aggregate throughput?

Check the link status LEDs and driver-reported speed; the firmware should show two active 100 GbE or HDR100 links.
