摘要：A computer system uses a Fibre Channel Arbitrated Loop (FC-AL) network to communicate with mass storage devices. The FC-AL network provides alternative communication paths to the mass storage devices. The FC-AL communication network includes a first ( 60 ) FC-AL controller within the FC-AL switch ( 50 ). A first FC-AL mass storage drive ( 56 ) has second ( 80 ) and third ( 82 ) FC-AL controllers. A first output of the first FC-AL controller is coupled to a first input of the second FC-AL controller, and a second output of the first FC-AL controller is coupled to a first input of the third FC-AL controller. A second FC-AL mass storage drive ( 94 ) has fourth ( 96 ) and fifth ( 98 ) FC-AL controllers. A first output of the second FC-AL controller is coupled to a first input of the fourth FC-AL controller, and a first output of the third FC-AL controller is coupled to a first input of the fifth FC-AL controller. The alternative communication paths to the mass storage devices reduces incident of disk drive access failure.
