Abstract

The invention relates to a single device for optimizing a redundant storage system, which includes a detection module for real-time detection of two interface states of a host to obtain detection results; a receiving module for receiving instruction information from the host and switching module, respectively connected to the receiving module and the detection module, for switching the two interfaces of the host according to the instruction of the receiving module and the detection result; Perform corresponding operations on the storage device according to the instruction information; the processing module includes a mirroring unit and a time management unit, and the time management unit is used to allocate access time to the storage device according to the operation result during the corresponding operation on the storage device . Different access times are assigned according to different reading results, so that the access time of the storage device is precisely controlled, the access efficiency of the host is improved, and the stability of the system and the efficiency of system information processing are greatly improved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a device for optimizing a single redundant storage system. Background technique [0002] Today, with the rapid advancement of science and technology and the explosive growth of network information, the processing, storage and backup of information data are particularly important. A redundant storage device is an additional storage device that can replace the main storage device when the main storage device fails. [0003] A redundant system is traditionally constructed with two main controllers and multiple storage devices, see figure 1 shown. figure 1 Including the host, two main controllers and multiple storage devices, in order to keep the host in working state without shutting down when one main controller or one storage device fails to operate normally, it is necessary to install an additional controller and several storage devices , and the host is connected to two ...
