The Cisco Nexus 9500 platform internally uses a clos fabric design that interconnects the line cards with rear-mounted fabric modules. The Cisco Nexus 9508 supports up to six fabric modules, each of which provides 5.12-Tbps line-rate packet forwarding capacity. All fabric cards are directly connected to all line cards. With load balancing across fabric cards, the architecture achieves optimal bandwidth distribution within the chassis.
