Based On The Three Layer Architecture Of Distributed Storage System Access Technology Research

Because of the rapid development of the internet technologies and the increasingnumber of network consumers, various data and information is exploding with a speedof3~5times a year, at the same time data is distributed in more and more broadgeographical space, a large number of applications which require better performance ofthe storage system appear, all of these bring more and more challenges to distributedstorage system. Therefore, the stunning significant issue of the storage systems forenterprises is how to construct a high-performance, available, highly scalable, safe andmanageable storage system.In allusion to the growing volume of business, the growing complexity of systempressure problems, this dissertation incorporate key technologies including datasegmentation, server clustering, reading and writing independency, loading balancing,and Coroutine concurrent to propose a Distributed Storage Access System with a3-tierarchitecture. This system provided a solution method which can do high-performancemass data storage access easily for the modern internet business, and improve theprocessing performance and availability of the distributed storage system. First, thisdissertation introduces the present distributed storage technology and the developmenttrend of distributed storage technology. And then this dissertation introduces the keytechnologies used by the system and the implementation of each module of the systemin detail and respectively. Finally, this dissertation completes the function test andpressure test of the system. And the tests results show that our approach has highperformance on user data handling and can satisfy the mass data storage requirements.
