Abstract

An air flow distribution adjusting mechanism for a disk array apparatus adjusts the distribution of air flowing in a disk array apparatus carrying a plurality of canisters. This air flow distribution adjusting mechanism includes an air flow distribution adjusting sheet for covering empty canister slots, and a sheet expanded length adjusting mechanism for adjusting the expanded length of the air flow distribution adjusting sheet.

Claims

1. An air flow distribution adjusting mechanism for a disk array apparatus for adjusting a distribution of air flowing in a disk array apparatus having a plurality of canisters, the air flow distribution adjusting mechanism comprising:

an air flow distribution adjusting sheet for covering empty canister slots; and

a sheet expanded length adjusting mechanism for adjusting an expanded length of said air flow distribution adjusting sheet.

2. The air flow distribution adjusting mechanism for the disk array apparatus according to claim 1, wherein said air flow distribution adjusting sheet has ventilation holes so that the air flows through the ventilation holes in the air volume equivalent to that of the air flowing between the canisters mounted in the empty slots.

3. The air flow distribution adjusting mechanism for the disk array apparatus according to claim 2, wherein the ventilation holes are formed so that the distribution of the air passing through the air flow distribution adjusting sheet becomes smaller in the area closer to the canisters.

4. The air flow distribution adjusting mechanism for a disk array apparatus according to claim 1, further comprising a locking mechanism for suppressing vibration of said air flow distribution adjusting sheet.

5. An air flow distribution adjusting mechanism for a disk array apparatus according to claim 1, wherein said air flow distribution adjusting sheet is made of a conductive sheet.

6. An air flow distribution adjusting mechanism for a disk array apparatus for adjusting a volume of air flowing in a disk array apparatus having a plurality of logical boards, the air flow distribution adjusting mechanism comprising:

an air flow distribution adjusting sheet for covering empty logical board slots; and

a sheet expanded length adjusting mechanism for adjusting a expanded length of said air flow distribution adjusting sheet.

7. An air flow distribution adjusting mechanism for a disk array apparatus for adjusting a distribution of air flowing in a disk array apparatus having a plurality of power supply boxes, the air flow distribution adjusting mechanism comprising:

an air flow distribution adjusting sheet for covering empty power supply box slots; and

a sheet expanded length adjusting mechanism for adjusting a expanded length of said air flow distribution adjusting sheet.
