NVIDIA Mellanox ConnectX-6 Dx EN MCX623105AN-CDAT

The NVIDIA Mellanox ConnectX-6 Dx EN MCX623105AN-CDAT is a single-port 100GbE network adapter built on the ConnectX-6 Dx ASIC, designed for organizations that need high-bandwidth, low-latency connectivity without the cost or power footprint of a dual-port card. It connects through a PCIe 4.0 x16 host interface and delivers a single 100GbE QSFP56 port with RoCE v2 RDMA offload, enabling efficient GPU-accelerated computing, storage networking and cloud data movement. As a baseline member of the ConnectX-6 Dx EN family, it carries the platform's core hardware offload capabilities — including SR-IOV network virtualization, overlay network acceleration and stateless TCP/IP offloads — while keeping the bill of materials lean for single-uplink server configurations. It is a practical choice for compute nodes, storage targets and edge servers that require 100GbE performance on a single link, and it shares firmware, driver and management tooling with the rest of the ConnectX-6 Dx product line for operational consistency.
