Problems solved by technology

[0004] In the process of practicing and researching the above-mentioned prior art, the inventors of the present invention found that: in the prior art, when the storage device is powered off, multiple control boards use the electric energy discharged from the battery module to simultaneously process the data in their respective storage modules Backup processing, so that the discharge current of the battery module is relatively large, that is, the discharge rate is large. According to the characteristics of battery discharge, when the discharge current is large, the discharge voltage platform is low, which has a great impact on the life of the battery module.

Abstract

The invention provides a data processing method for a storage system and a storage device, which are applied in technical field of device storage. After the storage system has power failure, the method for processing data comprises the following steps: totally backing-up the data in a corresponding cache to a safe box by a control panel; backing-up the data again by another control panel; and refreshing the data in the corresponding cache by other control panels in the process that data backup is carried out by one control panel. Therefore, the power consumption for refreshing the data is low, the storage system can reduce the discharge current of a battery module during power failure at the same time compared with the storage system in the prior art, and the consumed electrical energy isless, so that the power consumption on the battery module is reduced, the discharge rate of the battery module is also reduced, a discharge voltage platform of a battery is improved, and the service life of the battery module is prolonged.

Description

technical field [0001] The invention relates to the technical field of device storage, in particular to a data processing method of a storage system and a storage device. Background technique [0002] The storage device includes multiple control boards and multiple battery modules, wherein each control board has its own storage module for storing the data of the corresponding control board, such as high-speed cache memory module (CACHE), flash memory (flash), etc. A module that stores functions. When the storage device is powered off, each control board implements power-down protection measures for the data in its own storage module, and generally uses the electric energy discharged by the battery module to automatically refresh the data in the storage module to protect the data in the storage module not lost; or the data in the storage module is backed up to the safe of the storage device through the electric energy discharged by the battery module. The safe has a storage ...
