摘　　要：SWGFS是一种高可用的面向对象文件系统,目前已经在多个高性能集群系统中得到应用。与其它分布式存储系统类似,SWGFS也面临着数据管理工具短缺、数据管理效率低的困难,为此必须使用信息生命周期管理的概念。本文提出了一种面向对象的数据管理模型,这一模型为SWGFS引入了管理对象,并由其根据预先定义的管理策略直接操作文件对象,从而实现高效、准确的数据管理。通过原型系统的测试分析,该模型能满足SWGFS对于数据管理工具的功能和性能需求。SWGFS is an object-based file system with high availability and great capability, and has been adopted by many high performance cluster systems. With similarity to the other distributed storage systems SWGFS has difficulties in data management, such as lack of management tools and low management efficiency. The Information Lifecycle Management concept can solve all these problems. This paper prompts an object-based data management model, which introduces the management objects for SWGFS, and it manipulates file objects according the policies defined by users, so very good performance and accuracy can be achieved. The analysis of a prototype system proves the model which meets all the design goals.
