<p>A disk array unit (17) includes a motherboard (38), for example, housed in a case (21). The motherboard (38) has a plurality of hard disk drives (32) on its front surface. All the hard disk drives (32) are mounted upright on the surface of the motherboard (38). The motherboard (38) also has a plurality of hard disk drives (34) on its back. Since the motherboard (38) includes the hard disk drives (32, 34) on the front as well as on the back, they can be arranged in a limited space efficiently compared with the conventional disk array unit. As a result, the total storage of the disk array unit (17) can be increased without the expansion of the motherboard or an increase in the number of motherboards.</p> |
