Abstract:
A computer comprising:a controller board including an input/output (I/O) bus; a first set of disk drives; a second set of disk drives; a cable coupled to the controller board and one of the first and second set of disk drives, the cable adapted to couple the I/O bus to one of the first and second set of disk drives; and an integrated circuit associated with the first set of disk drives, the integrated circuit including a plurality of I/O data ports, one set of the plurality of I/O data ports coupled to the first set of disk drives, a sensing circuit coupled to the first set of disk drives and coupled to the one set of the plurality of I/O data ports, the sensing circuit sensing whether the first set of disk drives is coupled to the cable, and a bus port through which the voltage change is sensed to signal the cable is coupled to the first set of disk drives.
