Cisco MDS 9000 Family 8-Gbps Advanced Fibre Channel Switching Modules are available in two configurations:

- The 32-Port 8-Gbps Advanced Fibre Channel Switching Module delivers line-rate performance across all ports and is ideal for high-end storage subsystems and for Inter-Switch Link (ISL) connectivity.
- The 48-Port 8-Gbps Advanced Fibre Channel Switching Module provides higher port density and is ideal for connection of high-performance virtualized servers. With Arbitrated Local Switching enabled, this module supports 48-ports of line-rate 8-Gbps and is perfect for deploying dense virtual machine clusters with locally mapped storage. For traffic switched across the backplane, this module supports 1.5:1 oversubscription at 8-Gbps Fibre Channel (FC) rate across all ports.
The 8-Gbps Advanced Fibre Channel Switching Modules are compatible with all Cisco MDS 9500 Series Multilayer Directors, providing investment protection and outstanding low total cost of ownership (TCO).
