Nexus 7004 Architecture

The Cisco Nexus7004 is a 4 slot chassis, which comprises of 2 supervisor slots and 2 line card slots, 2 power supplies and 5 fabric channels.

The fabric channels are a little unique to the 7004 because although they are similar to the fabric2 modules, operating at up to 110Gbps each they are hardwired into the switch so they are not removable or upgradable. To allow for central arbitration and a management connection between the modules and supervisors one of the fabric modules is reserved for this, making the potential system fabric speed 440Gbps.

The above figure is dependant on the modules used in the chassis. Because there is only 2 slots the bandwidth between the two cards will be dependant on the slowest line, up to the potential 440Gbps.

Below is a picture showing the architecture.
