Table 4-3 mFCP Versus iFCP Purpose Feature OSI Layer 4 protocol mFCP iFCP LAN protocol to support short-distance SAN WAN Protocol to support extended-distance router connectivity SAN router connectivity User datagram protocol Transmission control protocol Link latency Low High Link bandwidth High Low Intelligent port operation No Yes FastWrite support No Yes Rate limiting support No Yes Data compression support No Yes Provides IEEE 802.3x flow control Yes Yes Provides IEEE 802.3AD link Yes No aggregation SAN routers must be configured on Yes No same subnet Inter-FlexPar Routing When the FlexPar feature is enabled for an Intrepid 10000 Director, the director is divided into multiple sub-directors, each operating with independent management and services. This consolidates application-based SAN islands, but does not enable device sharing between the SAN islands (sub-directors). Inter-FlexPar routing connects a SAN router to the Intrepid 10000 Director to enable authorized (zoned) communication between FlexPars. This is a unique application of SAN routing that enables communication between sub-directors in the same physical chassis, as opposed to routing between physically separate fabric elements. 4-28 McDATA Products in a SAN Environment - Planning Manual
