Keep demanding infrastructure on pace with a 100 GbE adapter built for dense server environments. NVIDIA ConnectX-5 MCX515A-CCAT pairs a single QSFP28 port with PCIe host connectivity to move large volumes of traffic with low latency and predictable throughput. It fits naturally into environments where storage access, virtualization, and distributed compute all compete for bandwidth. For teams standardizing on high-speed Ethernet, this adapter provides a clean path to 100 GbE without adding unnecessary complexity. The single-port design is well suited to servers that need one high-capacity uplink rather than multiple lower-speed connections, helping simplify cabling and switch planning. In practice, that means fewer bottlenecks when workloads spike and more headroom for critical applications. Choose this model when the network has to support sustained transfer rates, not just peak bursts. ConnectX-5 is designed for enterprise fabrics where latency, throughput, and port density all matter. It is a strong fit for storage clusters, virtualization hosts, and compute nodes that need dependable 100 GbE access from a proven NVIDIA adapter line.
