The invention relates to a single device for optimizing a redundant storage system, which comprises a detection module used for detecting the states of two interfaces of a host in real time to obtain a detection result; a receiving module used for receiving instruction information of the host, and a switching module respectively connected with the receiving module and the detection module and used for switching the two interfaces of the host according to an instruction of the receiving module and a detection result; and a processing module used for performing corresponding operation on the storage device according to the instruction information after the interface switching is completed; wherein the processing module comprises a mirroring unit and a time management unit, and the time management unit is used for distributing access time to the storage device according to an operation result in the process of performing corresponding operation on the storage device. Different access time is distributed according to different reading results, so that the access time of the storage device is accurately controlled, the host access efficiency is improved, and the system stability and the system information processing efficiency 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 ...
