Abstract: A cooling structure for electronic devices includes a plurality of electronic device accommodating boxes, in which electronic devices are accommodated, disposed in a casing in multiple stages. A vent portion which allows ventilation between the inside and the outside of the casing is formed in a ceiling of the casing. In a first accommodating portion for accommodating the first electronic device accommodating box which is defined at the stage close to the ceiling, a hollow duct having two opening faces is arranged. The first opening face faces the vent portion and the second opening face faces a second accommodating portion for accommodating the second electronic device accommodating box which is defined at the stage remote from the ceiling. Air inside the second electronic device accommodating box is discharged through the inside of the duct. Air inside of the first electronic device accommodating box is discharged from the vent portion.

Abstract: 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.
