The NEC QX-S6700E Series is a high-density 100 Gigabit Ethernet spine/leaf switch engineered for next-generation data center fabric architectures. The QX-S6720-30C variant delivers 30 ports of 100GbE connectivity in a compact form factor, supporting non-blocking line-rate performance across all ports. This switch is optimized for low-latency, high-throughput environments requiring predictable performance in modern cloud infrastructure and HPC deployments.
The QX-S6720-30C operates with a switching fabric capacity of up to 6 Tbps, accommodating dense east-west traffic patterns inherent in spine/leaf topologies. The platform supports advanced features including VXLAN, EVPN, and OpenFlow protocols, enabling flexible network virtualization and programmable control. Built-in redundancy, extensive buffer management, and comprehensive monitoring capabilities ensure reliability in mission-critical data center operations.
This switch is positioned for enterprises transitioning from 40GbE to 100GbE infrastructure, particularly those consolidating multiple rack-scale fabrics or scaling hyperscale cloud operations. The QX-S6700E Series supports standard Ethernet standards while integrating NEC's fabric management and telemetry tools for operational visibility.
