Abstract
A system including a first storage drive and a superior device superior to the first storage drive, wherein the superior device specifies a first allowable environmental temperature that makes the remaining lifetime of the first storage drive longer than the remaining operation schedule period of the first storage drive, and controls an environmental temperature adjusting device that adjusts the environmental temperature of the first storage drive on the basis of the first allowable environmental temperature.
Claims13
A system, comprising:
- a plurality of storage drives including a first storage drive;
- a superior device superior to the first storage drive;
- and
- an environmental temperature adjusting device that adjusts the environmental temperatures of the plurality of storage drives,
- wherein the superior device:
- specifies a first allowable environmental temperature that makes the remaining lifetime of the first storage drive longer than the remaining operation schedule period of the first storage drive;
- and
- controls the environmental temperature adjusting device to adjust the environmental temperature of the first storage drive on the basis of the first allowable environmental temperature,
- wherein, if the remaining lifetime of the first storage drive at a predefined environmental temperature is shorter than the remaining operation schedule period of the first storage drive, the superior device:
- determines a cost in a first operation in which the environmental temperature adjusting device is controlled on the basis of the first allowable environmental temperature without replacing the first storage drive;
- determines a cost in a second operation in which the environmental temperature adjusting device is controlled on the basis of a temperature equal to or higher than the predefined environmental temperature with replacing the first storage drive;
- and
- selects a more inexpensive one of the first operation and the second operation.
10 more elements
A method for controlling the environmental temperature of one storage drive or the environmental temperatures of a plurality of storage drives, comprising:
- specifying a first allowable environmental temperature that makes the remaining lifetime of a first storage drive longer than the remaining operation schedule period of the first storage drive;
- and
- controlling an environmental temperature adjusting device that adjusts the environmental temperature of the first storage drive on the basis of the first allowable environmental temperature,
- wherein the first storage drive is included among a plurality of storage drives, and the environmental temperature adjusting device adjusts the environmental temperatures of the plurality of storage drives, and
- the method comprising:
- specifying allowable environmental temperatures of the plurality of storage drives, each of the allowable environmental temperatures making the remaining lifetime of each of the plurality of storage drives equal to or longer than the remaining operation schedule period of each of the plurality of storage drives;
- and
- controlling the environmental temperature adjusting device on the basis of the lowest allowable environmental temperature among the allowable environmental temperatures.
