Product Description

The NVIDIA Mellanox ConnectX-3 Pro MCX349A-XCCN is an OCP 2.0 form-factor Ethernet adapter purpose-built for data center server motherboards. It uses a dual-chip architecture (two MT27528A0-FCCR-FV controllers) to deliver four 10GBASE-T RJ45 copper ports over a PCIe 3.0 x8 host interface. The OCP 2.0 card-edge design lets server vendors mount the adapter directly into a dedicated motherboard slot rather than a standard PCIe expansion bay, making it well suited to high-density server racks and facilities that need many standard copper Ethernet ports per node. The four-port layout lets a single card carry management, storage, and production traffic simultaneously, simplifying rack cabling.
