Abstract

For achieving installation of disk drives at high density, as well as, a large capacity and a high speed of the disk array apparatus, the disk array apparatus comprises disk drives, a box containing a large number of the disk drives in a direction of thickness thereof, wherein a throttle of flow passage, which combines a sour absorbing material in common, is provided above the disk drives in the downstream side of the disk array apparatus.

Claims

1. A disk array apparatus, comprising:

disk drives, which are mounted on a plural number of lines, in a direction of proceeding of an air flow;

a housing containing said disk drives therein; and

flow passages provided between an upper surface of said disk drives and an inner wall of an upper surface of said housing, for allowing said air flow to pass through, wherein

a dam is provided for narrowing said air flow, above said disk drives, in a downstream side of said flow passages.

2. The disk array apparatus, as described in the claim 1, wherein said dam is made of a sound absorbing material, and said dam is attached on the inner wall of the upper surface of said housing.

3. A disk array apparatus, comprising:

disk drives, which are mounted on a plural number of lines, in a direction of proceeding of an air flow;

a housing containing said disk drives therein; and

flow passages provided between an upper surface of said disk drives and an inner wall of an upper surface of said housing, for allowing said air flow to pass through, wherein

a shield plate is provided for shielding a direction of the air flow passing through said disk drives, in a downstream side of said flow passages, and on said shielding plate are provided openings corresponding to shapes of said disk drives.

4. The disk array apparatus, as described in the claim 3, wherein said shield plate is so disposed that spaces are opened alternately in a direction of height in a front and a rear of said disk drives.

5. The disk array apparatus, as described in the claim 3, wherein a heat sink is attached on one of sidewalls of each of said disk drives.

6. The disk array apparatus, as described in the claim 3, wherein a dummy is attached at a position where said disk drive is not installed.
