The NVIDIA ConnectX-6 MCX653106A-HDAT is a high-performance dual-port network card supporting 200Gb/s InfiniBand and Ethernet connectivity. Designed for data-intensive environments, this nic card features hardware offloads, in-network computing, and advanced security, making it ideal for HPC, AI, and cloud infrastructures.
The ConnectX-6 leverages InfiniBand Architecture Specification 1.3, RoCE (RDMA over Converged Ethernet), PCIe Gen 4.0, and hardware-based offloads for networking, storage, and security. It supports SR-IOV, overlay networks (VXLAN, Geneve), and advanced virtualization.
The nic card uses remote direct memory access (RDMA) to enable direct data movement between servers and storage, bypassing the CPU. Its in-network computing engines offload collective operations and encryption, reducing host overhead and improving efficiency.
