Cisco Systems announces the new Fabric 2 modules for Cisco Nexus 7000 Series switches. The newly announced Cisco Nexus 7000 Series Fabric-2 Modules for the Cisco Nexus 7000 Series chassis are separate fabric modules that provide parallel fabric channels to each I/O and supervisor module slot. From a scalability perspective, the new Fabric 2 module, enables the deployment of up to 768, 10 GbE ports in a Nexus 7000 chassis. The Fabric 2 module can deliver up to 550 Gbps per slot of performance. The new module also delivers connectivity, for only 9 watts of power per port.
Through the parallel forwarding architecture, a system capacity of more than 15 Tbps is achieved with the five fabric modules. The fabric module provides the central switching element for fully distributed forwarding on the I/O modules.
The newly announced Fabric 2 modules for Cisco Nexus 7000 Series switches is available for Cisco Nexus 7009, 7010 and 7018 Chassis. It seems Cisco Systems are coming out with a 9 slot chassis for Nexus 7000 Series Switch. The Fabric 2 module in combination with 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.
Some of the features and befits of the Cisco Nexus 7000 Series Fabric Modules are as follows
