摘要
基于云计算的存储系统,大都采用分布式存储.为了保证数据的完整性和一致性,增强数据的可靠性和可用性.通过划分服务区域、各服务区域内实行多层服务器集群的策略使用户无论何时、何地以何种方式都能高效、正确、完整地访问到所需数据.并根据数据需求量解决了数据副本数量的问题.与GFS分布式文件系统相比较,该策略思路清晰、实现简单.经仿真实验测试在数据访问、更新、删除及数据多版本方面有明显优点.
This specification is set for the theses to be published in Computer Applications and Software, including fonts, margins, page size and print area. Storage system based on cloud computing, mostly adopts the distributed storage. In order to ensure the integrity and consistency of data, enhance the reliability and availability of the data. By dividing the service area, service area to implement multi tier server cluster strategy users regardless of when, where and in what way can be efficient, correct and complete access to data. According to the data demand to solve the data copy number problem. Compared with the GFS distributed file system, the strategy of clear thinking, simple realization. There are obvious advantages in the simulation experiment test of data access, update, delete and multi version data.
