Design And Implementation Of Hierarchical Cloud Storage System Based On GlusterFS

With the rapid development and popularization of computer and information technology,different types of computers in various industries are used more and more.At the same time the contradiction between storage costs and data access speed can not be reconciled.The storage costs have increased dramatically by using high-speed data access storage media with the continuous expansion of storage capacity,and the use of low storage storage media,application data access speed does not meet the application requirements.In this context,storage systems with high-speed data access speeds and low data storage costs are crucial importance to applications and have great research value.This article first introduced the origin of hierarchical storage ideas,as well as the characteristics of hierarchical storage,and introduced the characteristics of the commonly used storage media.The necessity of reliability data migration between hierarchical storage migration are analyzed.Expounds the existing problems of reliable data migration,and proposes a new fast and reliable data migration method,then introduced the method of optimization parameters in hierarchical storage system based on GlusterFS,which made the performance of the method reach the optimum in the test system and greatly improved the efficiency of reliable data migration.In view of the low reliability of current distributed storage systems store data folder which contains a plurality of interrelated files,because a node failure may cause avalanche data loss.This paper introduces in detail the elastic hashing algorithm of GlusterFS and a distributed storage algorithm based on data folders is improved.After a node fails,it will not affect the data of other nodes and greatly improve the reliability of the system.At present,the storage system has the problems of configuration and monitoring,which require computer professional level for users,and difficulty in popularizing the application.This paper designs and implements a series of storage system configuration and monitoring services.The user can conveniently and quickly configure and monitor the entire Storage system,improve the system's applicability.
