Storage apparatus and control method therefor
First Claim
1. A disk array apparatus, comprising:
- a controller communicating with a host computer and storing data received from the host computer to a plurality of storage devices;
the plurality of storage devices having a power supply off state and a plurality of operation states other than the power supply off state; and
a fan cooling the plurality of storage devices,wherein the controller is adapted to cause a rotation speed of the fan to increase prior to causing an operation state of each of the plurality of storage devices to change from a first operation state to second operation state, in which an average power consumption of each of the plurality of storage devices is higher than the average power consumption of the one of the plurality of storage devices in said first operation state.

Abstract
A storage apparatus comprises at least one housing A in which a storage device and a controller are provided, at least one housing B in which a storage device and a peripheral device are provided, and a transmission path for connecting the storage device and the controller of the housing A, and the storage device of the housing B to enable communication therebetween. The storage apparatus is capable of controlling operation of the storage device of the housing B according to an operating state of the storage device of the housing A through communication via the transmission path; and controlling operation of the peripheral device according to an operating state of the storage device of the housing B.

6. A control method in a disk array apparatus, comprising the disk array apparatus performing steps of:
-
communicating with a host computer and storing data received from the host computer to a plurality of storage devices, wherein the plurality of storage devices have a power supply off state and a plurality of operation states other than the power supply off state; operating a fan to cool the plurality of storage devices, wherein operating the fan includes increasing a rotation speed of the fan prior to causing an operation state of each of the plurality of storage devices to change from a first operation state to second operation state, in which an average power consumption of each of the plurality of storage devices is higher than the average power consumption of the one of the plurality of storage devices in said first operation state. - View Dependent Claims (7, 8, 9, 10)
