ABSTRACT:
A storage device that is communicably connected to a host computer includes a plurality of disk units for storing data from the host computer. Each of the disk units includes a plurality of hard disks and is connected to one of a plurality of ports. A plurality of disk unit control units control the plurality of disk units, and each of the disk unit control units includes a memory for temporarily holding data from the host computer. A plurality of control signal transmission cables transmit control signals from the disk unit control units to the disk units. At least one of the control signal transmission cables is connected to at least two of the disk unit control units and transmits different control signals to at least two of the disk units. This enables device miniaturization and reduced costs for the storage device without a drop in reliability, even when a variety of devices are mounted in a highly dense configuration.
