Example Embodiment

[0071] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0072] Storage devices include interfaces, controllers, and storage media.

[0073] The interface is the physical link between the storage device and the host. The standard formats are USB (Universal Serial Bus), SATA (Serial Advanced Technology Attachment), SCSI (Small Computer System Interface) , Small Computer System Interface), FC (Fiber Channel), iSCSI (Internet Small Computer System Interface), etc.

[0074] The controller is used to manage the storage media and is responsible for data communication between the storage media and the host. The controller is generally a circuit board in form, and some complex controllers also run a software on the circuit board. The higher-end controller itself is actually a small comp...

Abstract

The embodiment of the invention provides a control method and device for storage equipment. The method comprises the following steps: acquiring computing power load information of a controller in a working state; judging whether the computing power of the controller in the working state is excessive or not by adopting the computing power load information; if the computing power of the controller in the working state is excessive, determining a first target controller from the controllers in the waiting state, and the first target controller is the controller in the waiting state with the maximum computing power information meeting the computing power load information and the lowest power consumption; and switching the controller in the working state from the working state to a waiting state, and switching the first target controller from the waiting state to the working state. According to the embodiment of the invention, the average power consumption of the storage equipment can be the lowest power consumption value under the condition of meeting resource use.

Description

technical field [0001] The present invention relates to the technical field of storage devices, in particular to a storage device control method and a storage device control device. Background technique [0002] A storage device is a device used to store information. A storage device generally includes three components: an interface, a controller (Controller) and a storage medium. [0003] Some storage devices with high reliability requirements will adopt a multi-controller structure in order to prevent the failure of the storage device due to the failure of the interface and the controller. [0004] refer to figure 1 It is a structural block diagram of an existing storage device with a multi-controller structure. In this kind of equipment, there are at least two interfaces and two controllers. Each interface and controller work independently and can transmit data with the host. Normally, only one group of interfaces and controllers are in working state (Working), while...
