The Cisco Nexus 7000 Series Switches provide the foundation of the Cisco Unified Fabric. They are a modular data center-class product line designed for highly scalable 10 Gigabit Ethernet networks with a fabric architecture that scales beyond 15 terabits per second (Tbps). Designed to meet the requirements of the most mission-critical data centers, it delivers continuous system operation and virtualized, pervasive services. The Cisco Nexus 7000 Series is based on a proven operating system, with enhanced features to deliver real-time system upgrades with no service disruption together with exceptional manageability and serviceability.

Switch fabric scalability is made possible through the support of from one to five concurrently active fabric modules for increased performance as your needs grow. All fabric modules are connected to all module slots. The architecture supports lossless fabric failover, with the remaining fabric modules load balancing the bandwidth to all the I/O module slots, helping ensure graceful degradation.

The combination of the Cisco Nexus 7000 Series fabric module and the supervisor and I/O modules supports virtual output queuing (VOQ) and credit-based arbitration to the crossbar switch to increase performance of the distributed forwarding system. VOQ and credit-based arbitration facilitate fair sharing of resources when a speed mismatch or contention for an uplink interface exists. The fabric architecture also enables future support for lossless Ethernet and unified I/O capabilities.
