ABSTRACT:
A shared data storage subsystem having a system controller embedded in a backplane of the shared data subsystem. The system controller monitors the TERMPWR signals of SCSI server busses physically coupled to the shared data subsystem to operably couple and isolate a server SCSI bus with the share data subsystem SCSI bus provides. The system can be used to isolate a server from a data storage subsystem without affecting the operation of other servers operably coupled to the data storage subsystem. The servers and shared data subsystem are implemented in a cluster system. The system controller also monitors environmental conditions of the shared data subsystem. The shared data subsystem includes a plurality of data storage devices such as hard disk drives which can be organized in a RAID configuration.
