Question
You are planning to use DWDM to connect two data center SANs that are located 200 km apart from each other. The Cisco MDS ports will be configured with 256 BB credits. These data centers will need connectivity for disaster recovery purposes and will be using full Fibre Channel frame sizes of 2112 bytes. Given these design parameters, can a default 2 Gb/s Cisco MDS TE_Port be used for connectivity, and why or why not?
