Abstract

The invention provides a data reading method, device and system. The method comprises the following steps: receiving a data reading request sent by terminal equipment, wherein the data reading requestcomprises: a data reading request, a source storage address of the target data, determining a source storage address based on the target data; determining all storage nodes of the target data; wherein all the storage nodes comprise a source storage node corresponding to the source storage address and at least one backup storage node, and when the source storage node meets a preset non-selection condition, determining a target storage node in the at least one backup storage node, and sending the storage address of the target storage node to the terminal equipment. In the technical scheme, theat least one backup storage node effectively shares the pressure of concurrent data reading of the user of the source storage node, and the concurrent data reading performance of the cloud storage system is improved on the premise of ensuring the data safety and availability.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data reading method, device and system. Background technique [0002] Cloud storage system is a kind of network storage system. Through functions such as cluster application, network technology or distributed file system, a large number of different types of storage devices in the network can be combined to work together through application software, and jointly provide data storage to the outside world. and business access functions. [0003] In the existing cloud storage system, in order to improve data security, a multi-copy storage scheme is adopted for data storage, that is, the user stores data to the source storage node assigned by the management server through the terminal device, and the source storage node stores the data. , and then back up the data to a determined backup storage node for storage. Correspondingly, when data is read, it is pref...
