基于Web服务的分布式文件系统管理与优化方案

摘要

To solve the problem of distributed file system such as lack of management standard, configuration complexity, im-proper distribution of node, poor efficiency of event processing, WBEM and WS-Management standard of DMTF are introduced to unify the management of distributed file system. Under the premise of management solution, resources of distributed file sys-tem are modeled by CIM standard and web services interfaces are supported by the system. The similarity strategy of node selec-tion in various environments is proposed and node storage space is used by event model to improve utilization of the distributed file system. The analysis results of experiments show that good performance and optimization of distributed file system are ac-quired by the management solution.%为了解决当前分布式文件系统中存在的缺少管理标准、配置复杂、结点分配不合理、事件处理效率差等问题,采用DMTF提出的WBEM和WS-Management标准来统一分布式文件系统的管理.提出了分布式文件系统管理的解决方案,时分布式文件系统中的资源进行了CIM建模和为它们提供了Web Services接口.提出了针对不同环境的分布式结点选择相近性策略和采用事件模型来充分利用结点剩余存储空间的方案,提高了分布式文件系统的利用率.对该方案进行了实验和分析,实验结果表明,该方案可以良好的管理和优化分布式文件系统.
