Fibre Channel Over Distance Solutions

Storage extension of Fibre Channel (and FICON) is critical, based on the importance of the data being transferred for Business Continuity and Disaster Recovery (BCDR) operations. Protocol transmission rate advancements, typical Fibre Channel frame sizes, and WAN equipment latency all alter the number of "Frames in Flight". All factors dictate an increased focus and proper architecting with respect to the Buffer-to-Buffer Credit (BBC) Flow Control mechanism as it is a critical factor that drives link performance.
