Cisco Nexus N9K-C9508-FM-E2 - Fabric Module

Cisco Part Number: N9K-C9508-FM-E2 is a Cisco Nexus 9500 4-slot 800Gbps cloud-scale fabric module (100G flows)

The Cisco Nexus 9500 platform is designed as a Clos fabric architecture, connecting each line card directly to each rear-mounted fabric module. This setup ensures that all traffic between the line cards is load-balanced across all fabric modules, optimizing bandwidth distribution within the chassis. This load-balancing capability enhances system reliability and redundancy, allowing the switch to continue operating even if a fabric module fails. In such a case, although the capacity is reduced, the remaining fabric modules maintain switching capacity to the line cards.

The Cisco Nexus 9500 Cloud Scale platform supports several fabric modules:

• 4-slot and 8-slot FM-G fabric modules, offering up to 1.6 Tbps capacity per line card slot.
• 8-slot and 16-slot FM-E2 fabric modules, providing up to 800 Gbps capacity per line card slot.
• 4-slot, 8-slot, and 16-slot FM-E fabric modules, also delivering up to 800 Gbps capacity per line card slot.

These fabric modules ensure upgradability and investment protection for the Cisco Nexus 9500 Series chassis. It is important to install fabric modules of the same type within a chassis to ensure compatibility and optimal performance.
