NVIDIA Mellanox ConnectX-6 MCX623102AS-GDAT

The NVIDIA Mellanox ConnectX-6 Dx MCX623102AS-GDAT is a dual-port 50GbE smart network adapter built on the ConnectX-6 Dx ASIC, delivering high-throughput, low-latency connectivity for modern data center and cloud infrastructure. Installed via a PCIe 4.0 x16 host interface, the card provides two 50Gb/s SFP56 ports with hardware-accelerated RDMA over Converged Ethernet (RoCE v2), enabling efficient remote direct memory access for storage and compute-intensive workloads. Secure Boot support protects firmware integrity from the moment the card powers on, guarding against unauthorized or tampered firmware in security-sensitive deployments. Built-in ASAP² hardware offload, SR-IOV, and overlay network acceleration reduce CPU overhead in virtualized and software-defined environments. As part of the ConnectX-6 Dx family, the MCX623102AS-GDAT is well suited to hyperscale cloud, NVMe-oF storage, and telco/NFV deployments that demand both performance and a hardened security posture.
