The Cisco Nexus 7000 series switches are the foundation of the Cisco Unified Fabric solution. Designed to meet the requirements of mission-critical data centers, these switches deliver exceptional availability, outstanding scalability, and the proven and comprehensive switching feature set. With extra high overall switching capacity, the Cisco Nexus 7700 switches deliver the high-capacity Gigabit Ethernet ports. This high system capacity is designed to meet the scalability requirements of the large cloud environments. Through the parallel forwarding architecture, a very high system capacity is achieved with the six fabric modules. The fabric module provides the central switching element for fully distributed forwarding on the I/O modules.
