NVIDIA Mellanox ConnectX-6 MCX614106A-CCAT

The NVIDIA Mellanox ConnectX-6 MCX614106A-CCAT is a dual-port 100GbE Ethernet-only adapter card featuring NVIDIA's Socket Direct technology, which splits the PCIe x16 interface across two physical PCIe 3.0 x16 connectors (via an auxiliary card and harness) to double available host bandwidth and enable direct, balanced access from either CPU socket in dual-socket server platforms. This architecture eliminates the latency and bandwidth penalty of inter-socket QPI/UPI traffic when a workload's CPU affinity does not match its NIC's PCIe socket, making it especially valuable for compute-intensive, NUMA-sensitive applications such as AI training and HPC. With native 100GbE connectivity over QSFP56, hardware-accelerated RoCE v2, and full ConnectX-6 offload capabilities, this card delivers high-throughput, low-latency networking for demanding dual-socket server deployments.
