NVIDIA Mellanox ConnectX-6 MCX653436A-HDAB OCP3.0

The NVIDIA Mellanox ConnectX-6 MCX653436A-HDAB is a dual-port OCP 3.0 small form factor (SFF) adapter card delivering up to 200Gb/s throughput over either HDR InfiniBand or 200GbE Ethernet from a single QSFP56 port pair, selectable in firmware. Built on the ConnectX-6 VPI (Virtual Protocol Interconnect) architecture, it combines industry-leading InfiniBand performance with advanced Ethernet capabilities, hardware-based RDMA (RoCE v2) and in-network computing acceleration (SHARP) to reduce latency and offload compute from the host CPU in AI, HPC, and hyperscale cloud environments. Its OCP 3.0 SFF form factor and PCIe 4.0 x16 host interface make it well suited for dense, hot-swappable deployment in modern rack servers standardized on the Open Compute Project specification. The card supports advanced telemetry, network virtualization (SR-IOV), and storage acceleration, giving data center operators a single adapter that can flexibly serve both InfiniBand clusters and high-speed Ethernet fabrics.
