Embodiment Construction

[0068] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific implementation of the distributed storage data access method and system of the present invention will be described below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0069] The data access method of the distributed storage of the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0070] S100. The master control server receives data access information, and sends the data access information to an index server.

[0071] S200, the index server finds the data node corresponding to the data access information, and returns the information of the data node to the main control server.

[0072] S300. The main control server connects to the data node to perform data access. ...

Abstract

The invention discloses a data access method and a data access system for distributed storage. The data access method comprises the steps that: a main control server receives data access information and sends the data access information to an index server; the index server looks up a data node corresponding to the data access information and returns information of the data node to the main control server; and the main control server is connected with the data node for data access. According to the data access method and the data access system for distributed storage, the index server only looks up data node information, the main control server is directly connected with the data node in subsequence, the stress on the index server is reduced, and the bottleneck of data node amount caused by the index server is removed; and in the process of carrying out data reading-writing by multiple main control servers simultaneously, multiple index servers can be used for decentralized processing, the storage performance of a distributed storage method is improved, equipment needed in the operation link of distributed storage is simplified and integrated, and the continuous availability of distributed storage is enhanced.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a distributed storage data access method and system. Background technique [0002] In the common distributed data access technology method, the main control server receives the data writing (storage) and reading requirements, finds the data node and data location related to the data through the location of the index server, and writes the data through the relevant data node Or read data to complete data access. The main defect of this mode of operation is that when there are actually more and more data nodes, for example, in the environment of big data applications, the increase of data nodes will relatively increase the pressure on the main control server and index server, so the performance of the overall operation There will be a bottleneck. Contents of the invention [0003] Based on this, it is necessary to provide a data access method and system for distributed sto...
