Abstract
Provided is a storage apparatus that uses a generally-used housing and allows storage devices mounted from two sides of the housing, in which a cooling device is provided in front of the storage devices and the cooling device is configured to be movable so as to open the front side of the storage devices so that maintenance and replacement of a storage device(s) can be performed from the two sides of the housing.
Claims13
A storage apparatus comprising:
- a housing that includes a first area and a second area located to the rear of the first area, the housing allowing storage devices to be mounted respectively from the first area and the second area;
- a first cooling device, provided on a first side facing the first area, including a first cooling unit and a second cooling unit that introduce outside air into the housing,
- wherein the first cooling unit and the second cooling unit are moved independently of each other;
- a second cooling device provided on a second side facing the second area, including a third cooling unit and a fourth cooling unit that expel to the outside of the housing the air introduced into the housing from the outside by the first cooling device,
- wherein the third cooling unit and the fourth cooling unit are moved independently of each other;
- a first drive circuit that drives the first cooling device;
- a second drive circuit that drives the second cooling device;
- a first device for moving the first cooling device between a first position where the first cooling device faces a storage device in the first area and a second position where the first cooling device opens the first side;
- and
- a second device for moving the second cooling device between a third position where the second cooling device faces a storage device in the second area and a fourth position where the second cooling device opens the second side,
- wherein a correspondence relationship is established between the first cooling unit and a plurality of first storage devices which are to be cooled by the first cooling unit, a correspondence relationship is established between the second cooling unit and a plurality of second storage devices which are to be cooled by the second cooling unit, a correspondence relationship is established between the third cooling unit and a plurality of third storage devices which are to be cooled by the third cooling unit, and a correspondence relationship is established between the fourth cooling unit and a plurality of fourth storage devices which are to be cooled by the fourth cooling unit,
- wherein a redundant array of inexpensive disks (RAID) group is configured with one of the plurality of first storage devices, one of the plurality of second storage devices, one of the plurality of third storage devices and one of the plurality of fourth storage devices,
- wherein the storage apparatus further includes a first power source unit arranged in the center of the first area and a second power source unit arranged in the center of the second area,
- wherein the plurality of first and second storage devices are arranged on right and left sides of the first power source unit in the first area, respectively, and
- wherein the plurality of third and fourth storage devices are arranged on right and left sides of the second power source unit in the second area, respectively.
