Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623106TN-CDAT is a dual-port 100GbE smart network adapter built on the ConnectX-6 Dx ASIC, delivering advanced hardware offloads for cloud, enterprise and hyperscale data center environments. Connecting through a PCIe 4.0 x16 host interface, it pairs two 100GbE QSFP56 ports with RoCE v2 for low-latency, high-throughput RDMA networking, making it a strong fit for AI/ML clusters, NVMe-oF storage fabrics and virtualized infrastructure. The card adds hardware support for PPS (Pulse-Per-Second) In/Out signaling, enabling precise time synchronization for latency-sensitive and telemetry-driven applications. Built-in hardware offloads for overlay networking, security and storage acceleration reduce CPU overhead and free host cycles for application workloads. As part of the broader ConnectX-6 Dx EN family, the MCX623106TN-CDAT gives data center architects a proven, field-validated adapter for scaling east-west and storage traffic without compromising compute density.
