Abstract
When a disk device corresponding to a logical volume is started, a disk system determines and starts a disk device and a fan to be started, while comprehensively considering heat quantity generated by the disk device to be started, the cooling capacity of the fan, and the electric power consumption of the fan or the electric power consumption of the disk device.
Claims14
A storage system comprising:
- a plurality of disk devices;
- a plurality of cooling devices;
- and
- a controller, coupled to the plurality of disk devices and a computer, configuring a plurality of logical volumes provided to the computer;
- wherein the controller is configured to confirm whether or not at least one disk device is in operation,
- if the at least one disk device is not in operation, the controller is configured to stop the at least one disk device,
- the controller is configured to identify whether or not at least one cooling device may be controlled to reduce electric power consumption based on stopping the at least one disk device, and
- if the at least one cooling device may be controlled to reduce the electric power consumption, the controller is configured to control the at least one cooling device.
A method for controlling a storage system which includes a plurality of disk devices, a plurality of cooling devices, and a controller, coupled to the plurality of disk devices and a computer, configuring a plurality of logical volumes provided to the computer, wherein the method comprises the controller:
- confirming whether or not at least one disk device is in operation,
- if the at least one disk device is not in operation, stopping the at least one disk device,
- identifying whether or not at least one cooling device may be controlled to reduce electric power consumption based on stopping the at least one disk device, and
- if the at least one cooling device may be controlled to reduce the electric power consumption, controlling the at least one cooling device.
