$39,011
The Cisco C1-N5K-C5648-B-36Q is an enterprise-class, high-speed 1RU rack-mountable switch, positioned for agile data center application. Featuring 36 QSFP+ ports with 40Gbps per port, it enables seamless backbone aggregation and powerful FCoE switch performance—making it ideal for storage, virtualization, and next-gen network fabric. Its non-blocking switch fabric capacity of 1.44 Tbps and forwarding rate up to 1.44 billion packets per second deliver uncompromising throughput for dense and latency-sensitive cloud or enterprise deployments. The C1-N5K-C5648-B-36Q natively supports FCoE, offering unified fabric for convergence of LAN and SAN traffic, while integration with Cisco DCNM brings robust centralized management and automation capabilities for operators and integrators. With hot-swappable redundant power and fans, advanced hardware QoS, and full L2/L3 protocol coverage (OSPF, BGP, EIGRP), this solution provides resilient high availability and operational flexibility for medium to large-scale deployments. Tailored for professional users across Asia, Europe, North America, and Africa, the switch is the optimal core solution for scalability, cloud connectivity, and software-defined networking environments, proven to meet international enterprise performance standards. Its shared dynamic buffer adapts to diverse traffic profiles, while Cisco NX-OS ensures advanced modular software features and long-term investment protection.
