Disk array device
First Claim
1. A disk array device comprising:
- a storage unit;
a controller for controlling storage of data into said storage unit;
a power unit for supplying power to each section;
a fan for air cooling an interior of a housing;
a backboard for connecting each section, the storage unit being connected to one surface of the backboard through a connector;
a cooling function of allowing cooling air to flow into the housing by an operation of said fan and exhausting the cooling air from the housing via a region to which said storage unit is installed and a vent hole provided in said backboard; and
a shutter having a mechanism which corresponds to the vent hole of said backboard and in which an open area rate of said vent hole is adjusted by opening in accordance with mounting of said storage unit and closing in accordance with unmounting thereof.

Abstract
In a disk array device for cooling respective sections including a HDD by a fan, drop of cooling efficiency by the difference of conditions of HDD mounted and unmounted sections is prevented and the use of a dummy HDD is deleted/eliminated. A housing contains a HDA mounted on the HDD, a power controller board for performing control to the HDD, a power unit for supplying power to each section, a fan for cooling the housing therein, and a backboard for connecting all the sections. On one backboard surface, the HDA is mounted, which has a cooling function for making cooling air flowing in the housing and exhausting air from the housing via a region on which the HDA are mounted and via a vent hole on the backboard. For the vent hole, a shutter is mounted, which has a mechanism for adjusting an open area rate of the vent hole by opening when the HDA is mounted and closing when removed.
