Embodiment Construction

[0051] In view of the deficiencies in the existing technology, it is necessary to temporarily store the data information that should be stored in the reconstructed storage array through corresponding storage resources during the process of rebuilding the storage array. In order to ensure the continuity of the storage business, the reconstruction of the storage array After completion, the corresponding data storage services also need to be restored to the rebuilt storage array.

[0052] Based on such a technical idea, the present invention proposes a disk array reconstruction method, which is applied to a system including a data management server, multiple storage devices and multiple encoding devices, and the encoding devices store data information in the corresponding storage devices , the data management server is used to manage multiple storage devices, and the storage devices include one or more storage arrays.

[0053] Based on the above purpose, if figure 2 As shown, i...

Abstract

The invention discloses a disk array reconstruction method and a device. By utilizing the technical scheme, during the reconstruction process of the array, the pressure of data stream can be shared by other memory devices with surplus capacity so as to accelerate the reconstruction process, so the monitored data is free from being lost caused by the decrease of the array reconstruction performance, the reading and writing reliability of the data of the system can be improved, and the processing efficiency of the array reconstruction in the system can be improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for rebuilding a disk array. Background technique [0002] In the video surveillance business, the video signal enters the EC (video codec) through the camera, and the 1-second data is compiled into an I frame group (composed of one I frame and multiple P frames) with a specified bit rate through the encoding module. In this process, every compiled I frame or P frame will be put into the buffer area of ​​EC. The EC packet sending module fetches one I frame group (1 second data) from the cache area each time, and sends the message to the storage device through the TCP (Transmission Control Protocol, Transmission Control Protocol) protocol. The storage device returns a feedback message after storing the message data in the data disk to inform the EC to continue sending, and the packet sending module reacquires an I frame group from the buffer area, and c...
