Construction method and device of storage system

Abstract

The embodiments of the invention provide a construction method and device of a storage system, wherein the storage system has a dynamically adjustable characteristic and a high disaster recovery characteristic. According to the technical schemes of the invention, the method includes the following steps that: the node parameters of the storage system are determined; information nodes and check nodes are numbered sequentially; a {0, 1} random vector is generated for each of the check nodes; and encoding relations are established between each of the check nodes and the information nodes: elements in corresponding random vectors of the check nodes, of which the value is 1, are determined, information nodes corresponding to positions where the elements of which the value is 1 in the random vectors are located are determined, and exclusive OR operation is performed on the corresponding information nodes sequentially, and an operation result is adopted as the data of updated check nodes. With the construction method and device provided by the technical schemes of the invention adopted, operation cost is decreased when the storage system is constructed, and computational efficiency is improved, high reliability can be realized with low redundancy consumption. The construction method and device have excellent node dynamic adjustment capability.

Description

technical field [0001] The invention relates to the technical field of coding organization and storage of electronic information files, in particular to a storage system construction method and device. Background technique [0002] In recent years, with the rapid development of the Internet, cloud computing, mobile terminals and the Internet of Things, the global data volume has entered the ZB era in 2010 and continues to grow every year. The world has already entered the data-centric information age, and how to store data efficiently, reliably, and safely has become the cornerstone of the information age and the primary issue in the storage field. [0003] At present, the distributed storage system is gradually replacing the traditional single-point storage mode with a new storage mode based on the Internet. It can build a system at a low cost and achieve highly reliable mass data storage, and has now become the preferred solution for "big data" companies. [0004] The cu...
