In a storage device accommodating a plurality of memory devices in a general-purpose chassis provided from both surface sides thereof, a cooling device is provided on the front of the memory devices. This cooling device is allowed to freely move to leave available the area in front of the memory devices, thereby enabling maintenance and replacement of the memory devices from the both surface sides of the chassis. With such a storage device of a type using a general-purpose chassis, and inserting therein a plurality of memory devices from the both surface sides thereof, even if a cooling device is located on the front of the chassis, the memory devices can be subjected to maintenance and replacement.

A control unit is proposed which makes it possible to prevent connection problems between a package box and a backboard and prevent damage to the connector of the backboard. The control unit comprises a unit cover in which a first package box, which comprises a predetermined function and on the rear side of which a first connector is provided, is inserted into the corresponding spatial area so as to move over a shelf from an open end [of the unit cover]; and a backboard which is disposed inside the unit cover and on which a second connector is provided in a position where the first package box, inserted in the corresponding spatial area, mates with the first connector, wherein the shelf is provided with a protrusion which rotatably supports the first package box in a fan direction.

A storage apparatus has a cabinet stored with an array of memory mediums, a power supply unit housed at the bottom of the cabinet, a fan provided immediately under the top surface of the cabinet and immediately above the memory mediums, and a partition member provided insides the cabinet and configured to partition a first cooling path from mixing with a second cooling path inside the cabinet. The first cooling path of first external air for cooling the memory mediums starts at an inlet on a side surface of the cabinet and ends at the top surface of the cabinet to discharge the first external air out of the cabinet form the top surface. The second cooling path of second external air for cooling the power supply unit ends at the top surface of the cabinet and discharges the second external air out of the cabinet at the top surface.

Provided is a cooling method for realizing the efficient cooling of a storage apparatus. Used for this cooling method is a storage apparatus having a cabinet for storing a plurality of memory mediums in an array, and a power supply unit for supplying power to a drive circuit of the memory mediums. The power supply unit is housed inside the ground plane side of the cabinet, and the plurality of memory mediums are housed inside the cabinet on the power supply unit. This storage apparatus includes a first cooling path to become a passage inside the cabinet of first external air for cooling the plurality of memory mediums, and which ends at an upper end portion of the cabinet, a second cooling path to become a passage inside the cabinet of second external air for cooling the power supply unit, and which ends at the upper end portion of the cabinet, a fan provided to the upper end portion of the cabinet so as to face the memory mediums positioned immediately below from the end of the first cooling path, and for drawing in the first external air to the first cooling path and discharging the first external air that cooled the plurality of memory mediums outside the cabinet, and a partition member for partitioning the first cooling path and the second cooling path so that the first external air and the second external air do not get mixed. The fan is supported by the cabinet so as to be slanted against a peripheral part of the memory mediums positioned immediately below the first cooling path.

A disk array apparatus facilitating the management of dummy boards which are dismounted when logic boards are additionally installed, for example. A storage section for storing dummy boards, which are removed when logic boards are additionally installed, is provided in the disk array casing. The storage section is provided in a place where the dummy boards do not adversely affect the passages of the flow of cooling air in the disk array casing and the work of mounting or dismounting the component parts on the rear side of a platter cover for shielding the logic section where logic boards are accommodated, for example, and the dummy boards are fixed to the storage section with screws.
