For the most demanding storage networking environments, the Cisco MDS 9000 Family 24-Port 8-Gbps Fiber Channel Switching Module delivers uncompromising performance. The front panel ports deliver up to 192 Gbps of full-duplex bandwidth, making this module best suited for attachment of 4- and 8-Gbps-enabled storage subsystems and for Inter Switch Link (ISL) connectivity. With its multiprotocol capability, the 24-Port 8-Gbps Fiber Channel Switching Module transparently integrates FICON protocol, FICON Control Unit Port (CUP) management, and switch cascading to enable mainframe connectivity. Virtual SANs (VSANs) allow hardware-based separation of Fiber Channel and FICON traffic switched on a single physical SAN, lowering overall TCO without compromising your network's scalability, availability, manageability, and security.
