Mellanox CX-5 MCX515A-CCAT 100GbE QSFP PCIe NIC | Enterprise Network Adapter — UCSC-P-M5S100GF

Move data at 100 GbE speeds with a PCIe network adapter designed for infrastructure that cannot afford bottlenecks. The Mellanox CX-5 MCX515A-CCAT gives server teams a direct path to higher throughput for virtualization hosts, storage fabrics, and latency-sensitive application tiers. Built around a single QSFP port, this adapter is suited to environments where port density, predictable performance, and clean server integration matter more than commodity connectivity. It is a strong fit for consolidation projects, high-performance compute nodes, and back-end networks that carry large volumes of east-west traffic. For teams standardizing on Cisco infrastructure, this adapter aligns with enterprise deployment expectations and supports the kind of sustained bandwidth that cheaper 10 GbE options cannot match. It is the right choice when the network must keep pace with modern workloads, not slow them down. Ideal For High-performance compute nodes requiring 100 GbE uplinks Virtualization hosts carrying heavy east-west traffic Storage fabrics that need low-latency, high-throughput connectivity Clustered application servers in dense data center racks Why This Product 1 100 GbE bandwidth for demanding server workloads 2 Single QSFP port for streamlined high-speed connectivity 3 PCIe interface for direct server integration 4 Better fit for dense infrastructure than 10 GbE adapters
