Product Description
The NVIDIA Mellanox ConnectX-4 EN MCX415A-CCAT is a single-port 100 Gigabit Ethernet network adapter card built around the ConnectX-4 EN controller (MT27708A0-FDCF-CE), delivering full-bandwidth 100GbE connectivity over a QSFP28 port through a PCIe 3.0 x16 host interface. Unlike the cost-optimized ConnectX-4 Lx family, the ConnectX-4 EN silicon is designed for full line-rate 100Gb/s throughput and supports RDMA over Converged Ethernet (RoCE v2), offloading data transport from the host CPU to minimize latency for storage, compute and network-intensive workloads. As a standard PCIe add-in card in the Legacy Adapters line, the MCX415A-CCAT is a widely deployed choice in enterprise, cloud and HPC server environments requiring maximum single-port Ethernet bandwidth, including scale-out storage clusters, RDMA-accelerated database tiers and compute-node interconnects that outgrew 10/25/40GbE infrastructure.
