Database management system for controlling power consumption of storage system
First Claim
1. A database management system that runs on a computer coupled to a storage system, wherein the storage system includesa plurality of storage devices,a power control module that performs power control of the plurality of storage devices, andan interface module that receives a power conservation instruction from the computer and transfers the power conservation instruction to the power control module, wherein the database management system comprises:
- an access module that performs access of data stored in a first type storage device among the plurality of storage devices and detects a fault relating to the access;
a storage device specifying module that specifies a second type storage device, among the plurality of storage devices, that stores a backup corresponding to the data that are stored in the first type storage device when the access module detects a fault relating to the access of the data; and
a power consumption control module that issues a power conservation cancellation instruction to cancel the power conservation for the specified second type storage device to the interface module of the storage system.

Abstract
When performing access relating to a first type storage device among a plurality of storage devices in the storage system, the database management system specifies a second type storage device that stores a backup of data that are stored in the first type storage device if an error relating to the access is detected and issues a power conservation cancellation instruction to cancel the power conservation of the second type storage device.

13. A computer system, comprising:
-
a storage system comprising a plurality of storage devices, a power control module, and an interface module; and a computer comprising a database management system, wherein the computer comprises; an access module that performs access of data stored in a first type storage device among the plurality of storage devices and detects a fault relating to the access; a storage device specifying module that specifies a second type storage device, among the plurality of storage devices, that stores a backup corresponding to data that are stored in the first type storage device when the access module detects a fault relating to the access of the data; and a power consumption control module that issues a power conservation cancellation instruction for canceling the power conservation of the specified second type storage device to the interface module of the storage system, and wherein; the interface module receives the power conservation cancellation instruction and transfers the power conservation cancellation instruction to the power control module; and the power control module cancels, in response to the power conservation cancellation instruction, the power conservation of the second type storage device specified by the power conservation cancellation instruction. - View Dependent Claims (14)

16. A power control method that is executed by a computer system having:
-
a storage system having a plurality of storage devices, a power control module and an interface module; and a computer having a database management system, the method comprising; a step in which the database management system performs access of data stored in a first type storage device among the plurality of storage devices and, when a fault relating to the access is detected, specifies a second type storage device among the plurality of storage devices that stores a backup corresponding to the data that are stored in the first type storage device; a step in which the computer issues a power conservation cancellation instruction to cancel the power conservation of the specified second type storage device; a step in which the interface module of the storage system receives the power conservation cancellation instruction from the computer and transfers the power conservation cancellation instruction to the power control module of the storage system; a step in which the power control module of the storage system cancels the power conservation of the second type storage device specified by the power conservation cancellation instruction.
