DEVICE ABOUT AN IMPROVED BRIDGE DEVICE WHICH COMBINES A FIBER CHANNEL STORING DEVICE WITH A FIBER CHANNEL ARBITRATING LOOP COMMUNICATION MEDIUM

摘要

PURPOSE: A device about an improved bridge device which combines a fiber channel storing device with a fiber channel arbitrating loop communication medium are provided to combine a FC-AL(Fiber channel Arbitrated Loop) loop with a plurality of storing device, thereby enhancing the flexibility in each enabling and bypass of a plurality of non-FC storing device.;CONSTITUTION: A bypass control logical circuit(104) maps one among a plurality of T-ALPA with each plurality of devices(110.1~110.n). To perform bypass and enable of individual device of a plurality of storing device without relating the status of other devices among a plurality of storing devices, the bypass control logical circuit proceeds a LPE(Loop Port Enable) and a LPB(Loop Port Bypass) fiber channel primitive sequence about each plurality of T-ALPA(Target-Arbitrated Loop Physical Addresses).;COPYRIGHT KIPO 2011
