The 24-Port 8-Gbps Fiber Channel Switching Module delivers the highest performance for high-end storage subsystems and for Inter Switch Link (ISL) connectivity.The 8-Gbps Fiber Channel switching modules are compatible with all MDS 9500 Series Multilayer Directors, enabling you to continue to use your existing 2- and 4-Gbps MDS 9000 Family Fiber Channel switching modules and gradually phase in 8-Gbps technology as your network demands it.Cisco MDS 9000 Family 8-Gbps Fiber Channel switching modules deliver the intelligence and the high performance required to support the most demanding storage applications, providing the foundation for large scale Storage Area Network (SAN) consolidation. Delivering up to 528 8-Gbps ports per chassis and twice the bandwidth of previous switching modules, the 8-Gbps Fiber Channel switching modules enable you to build consolidated SANs with fewer chassis for dramatic savings in space, power and cooling, and total cost of ownership (TCO).
