Product Description
The NVIDIA Mellanox ConnectX-4 MCX413A-GCAT is a single-port 50GbE Ethernet (EN) network adapter built for enterprise and cloud servers that need high-throughput, RDMA-capable Ethernet connectivity. It connects over a PCIe 3.0 x8 host interface and uses a QSFP28 port to reach 50Gb/s Ethernet speeds, with RoCE v2 support delivering RDMA-class low latency and CPU offload for storage and virtualization traffic over standard IP fabrics. Built around the Mellanox MT27708A0-FDCF-CE controller, part of the ConnectX-4 EN silicon family, it targets deployments where Ethernet-only connectivity (rather than InfiniBand) is the requirement. As a ConnectX-4 generation adapter (circa 2015-2018), it is a widely deployed, field-proven building block for enterprise data centers, cloud infrastructure, and storage networks needing 50Gb/s-class Ethernet with hardware-accelerated RDMA. The MCX413A-GCAT ships under NVIDIA ordering SKU 900-9X426-0015-ST0.
