Abstract

A high-density disk array device can enhance accessing capacity and heat-dissipating capacity, which includes a casing formed with an entry. A pair of disk modules and a pair of fan modules are received in the casing. The pair of disk modules can be drawn from the entry of the casing. Each of the disk modules has a plurality of hard disks received therein in a drawable way, a power module and an input/output module. The pair of fan modules are arranged adjacent to an outer side of the pair of disk modules correspondingly. A central passageway is formed between the pair of disk modules. After the disk module is drawn out from the casing, the hard disks can be drawn along a direction perpendicular to the central passageway.

Claims

1. A high-density disk array device, comprising

a casing, has a entry formed at a front surface thereof;

and

a pair of disk modules, received in said casing and is drawable outwardly from said entry of said casing, wherein each of said disk modules has a plurality of hard disks received therein in a drawable way, at least one power module, and at least one input/output module, said power module and said input/output module adjacent to a rear surface of said casing and electrically connecting to said hard disks;

wherein

a central passageway formed between said pair of disk modules, when said disk modules is drawn outside from said casing, said hard disks are drawable along a direction perpendicular to said central passageway.

2. The high-density disk array device as in claim 1, wherein said casing has a front-central ventilating panel and a rear-central ventilating panel respectively disposed at a front end and a rear end of said central passageway.

3. The high-density disk array device as in claim 1, further comprising a pair of fan modules received in said casing and adjacent to an outer side of said pair of disk modules correspondingly.

4. The high-density disk array device as in claim 3, wherein each of said fan modules has a front fan module, and a rear fan module.

5. The high-density disk array device as in claim 4, wherein said front fan module and said rear fan module respectively has a locking arm.

6. The high-density disk array device as in claim 4, wherein said front fan module takes in air from a front end of said central passageway and forms a front airflow, said rear fan module takes in air from a rear end of said central passageway and forms a rear airflow, said front airflow and said rear airflow pass through said pair of disk modules and are exhausted via the front end of said front fan module and the rear end of said rear fan module.

7. The high-density disk array device as in claim 3, further comprising a pair of sub-casings received in said casing and disposed at two sides of said central passageway, each of said sub-casings has a said disk module and a said fan module.

8. The high-density disk array device as in claim 7, wherein each said sub-casings has a handle mounted on a front surface thereof and at least one lock on a front surface thereof to lock said casing.

9. The high-density disk array device as in claim 7, wherein said pair of sub-casings respectively has a stopping block protruded toward said central passageway, said casing has at least one a front-positioning block and at least one rear-positioning block on a moving paths of each of said stopping block correspondingly.

10. The high-density disk array device as in claim 7, further comprising a crash cushion disposed at an inner side of the rear end of said casing to absorb an impact when the sub-casing contacts with the casing.

11. The high-density disk array device as in claim 1, wherein said hard disks of said pair of disk modules are arranged in an erect way, said hard disks are arranged abreast with a gap between each other.
