Embodiment Construction

[0024] First, a data storage method in an embodiment of the present invention is described, including:

[0025] Pre-dividing the storage nodes in the system into active domain nodes and dormant domain nodes; wherein, the dormant domain nodes are in a standard working state during system non-idle periods, and are in a low power consumption state during system idle periods;

[0026] During the non-idle period of the system, perform data read and write operations on the active domain node and the dormant domain node;

[0027] During the idle period of the system, data read and write operations are performed on the active domain nodes.

[0028] Although most storage systems need to be in operation for a long time, in practical applications, the data access of many storage systems is characterized by periodic changes. For example, the data access volume of internal data servers during non-working hours is significantly higher than that of During working hours, the data access volu...

Abstract

The embodiment of the invention discloses a method, a device and a system for storing data. The method for storing data comprises the following steps: data reading and wiring operation is performed on nodes in an active domain and a dormant domain which are divided in advance during the non-idle time period of a system, and data reading and wiring operation is performed on nodes in the active domain which is divided in advance during the idle time period of the system. The nodes in the dormant domain are in a standard working state during the non-idle time period of the system and in a low-power consumption state during the idle time of the system. During the idle time period of the system, data reading and wiring operation is only performed on the nodes in the active domain, while the nodes in the dormant domain are in the low-power consumption state. The invention can effectively reduce the power consumption of the whole system on condition that the data access requirement is met.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data storage method, device and system. Background technique [0002] With the continuous development of the information society, the amount of global digital information has grown rapidly in recent years. The increase in the amount of information also puts forward higher requirements for the data storage system. On the basis of providing high-capacity storage space, the reliability and access performance of the data must be further improved. [0003] In the prior art, a common method is to improve data reliability or read / write performance by establishing a multi-disk storage system. For example, RAID (Redundant Array of Independent Disk, Redundant Array of Independent Disks) technology is to combine multiple independent hard disks into a storage system through a RAID controller, and data is stored on each independent hard disk. On the one hand, redundant data c...
