Abstract

The present application provides a data processing method and device on a multi-control storage system, which can enable the controller to receive a disk brush instruction, and determine the target fingerprint corresponding to the target cache data based on the disk brush instruction; based on the local record storage controller, The corresponding relationship between the write cache address of the storage controller and the fingerprint, and obtain the target storage controller and the target write cache address corresponding to the target fingerprint; when the controller is not the target storage controller, it will carry the target fingerprint and the target write cache address; The control information of the target write cache address is sent to the target storage controller, so that the target storage controller obtains the corresponding target cache data in the local write cache according to the control information, and performs the disk flushing process. Therefore, the present application can only transmit the fingerprint of the target cache data and the target write cache address when flashing the disk, without transmitting the data, thereby avoiding preemption of bandwidth resources with the mirror image data, and improving the processing efficiency of the written data.

Description

technical field [0001] The present application relates to the technical field of deduplication, and in particular to a data processing method and device on a multi-controller storage system. Background technique [0002] A multi-controller storage system refers to a storage system with more than two controllers. The more controllers there are, the stronger the processing capability of the storage system is. At the same time, the controllers are hot-backed up to each other, so the reliability is higher. In a multi-controller storage system, each controller has an independent CPU, memory, and IO interface device, so each controller has an independent computing capability; each controller can also transmit information to each other, and each The controller will be connected to the hard disk and can access all the stored data in the hard disk space. [0003] In related technologies, when data is written in the multi-controller storage system, the controller can mirror the local...
