Abstract

The invention discloses a data writing method and a data writing device for a controller. The method comprises the steps of when the controller receives data to be written into, transmitting the datato preset storage equipment, and writing the data into the preset storage equipment. A system comprises at least two controllers, and the preset storage equipment and each controller can transmit dataseparately. According to the data writing method and device for the controller provided by the invention, the controller writes the data into the preset storage equipment, when the controller is in failure, the other controller can read the data from the preset storage equipment, so that the condition that the data is not lost is ensured; furthermore, writing of the data is completed after the data is written into the preset storage equipment; compared with the prior art, the method is reduced in writing step and simplified in writing process. The invention also discloses a task execution method.

Description

technical field [0001] The invention relates to the technical field of data protection, in particular to a controller data writing method and device. The invention also relates to a task execution method. Background technique [0002] In the prior art, in order to ensure no data loss when a single controller is damaged in the storage cluster system, dual controllers are used to implement data mirroring between the two controllers, that is, one of the controllers backs up the other controller Specifically, when a controller front-end interface writes data, it simultaneously writes a copy of the same data to the mirror memory of the peer controller to realize data backup; when the peer controller returns the write completion The current data writing process is considered complete when the instruction message is displayed. In such a writing mode, the completion of writing needs to be confirmed by both controllers at both ends, which results in many writing steps and complicat...
