Abstract
A multiplexing system and method for servicing serially linked targets or RAID devices. The multiplexing system couples service interfaces from various targets and devices. The multiplexing system provides a single service link to a single service unit interface. The single service link allows easy access/communications or remote access/communications to an individual target or disk drive within the RAID system. A service unit is directly or remotely coupled to the service unit interface. The multiplexing system has an outgoing multiplexer, an in-going multiplexer, and a multiplexer controller. The service unit communicates with the multiplexing system to select the desired target or disk drive to be serviced. The multiplexer controller detects incoming select target commands and compares incoming target address information with a presently defined multiplexer controller target address information. A switch command is activated or occurs when the incoming select target address information is different with the presently defined multiplexer controller target address information. The multiplexing system accordingly switches to a different target or disk drive to be looked at and serv…
