Research On Glusterfs Architecture And Performance Optimization Of Distributed File System

Mass Storage file System used to store large amounts of data , Mass Storage System can linear scaling.lt increases the complexity of file System. Parallel File System (the Parallel File System) is made by different storage host form a storage cluster, the nodes in the cluster have Parallel relationship.It can complete the Parallel computing and Parallel storage. Distributed file system is the foundation of cloud storage. To provide scalable, transparent, fault-tolerant, management, and other related featuresFirst of all, the distributed file system research, GlusterFS architecture and function.Including distributed file system development, several of the comparison of the distributed file system, function of distributed file systems in the desktop virtualization,and GlusterFS system architecture.Secondly, GlusterFS function optimization analysis.Analysised of the algorithm process, the cluster characteristics and advantages ,encryption function, performance optimization and the optimization scheme.Thirdly, GlusterFS encryption function optimization.ROT13 function module is the original ideas of encryption, using key management system and the encryption card to replace the original encryption module.Then, analysis the optimization strategy of the performance optimization strategy.Including pre-read, caching,merge IO operation, striping and multi-thread technology, and the use of cache priority algorithm.Finally, set up the experimental environment, through test to prove the validity of the optimization scheme, parallel file system test.Parallel file system performance testing index mainly through reading and writing speed to compare.This thesis mainly researches on the parallel file system GlusterFS realization method and related function strategies.Confirmed the storage performance optimization scheme by test.
