摘要： 为对网格文件进行数据访问，提出一个带有标准服务器和协议的高性能存储系统——联众系统。采用集群环境中的数据管理方法，通过使用多个标准数据服务器访问多个站点，采用的技术包括Grid FTP以及OGSA Byte I/O界面等。实验结果证明，联众系统能够被用作真实网格环境中的并行文件系统，并获得较好的数据访问结果。

Abstract: This paper proposes a high-performance memory system with the standard server and protocol——Union System, to address the issue of grid file access. It adopts the data management method which is used in the cluster environment and enables the access of multi-sites through multi-standard data servers. The technologies applied include Grid FTP and OGSA Byte I/O interface, etc. It turns out that the Union System can be used as a parallel file system in the real grid environment and can achieve the excellent result of data access.

Key words: distributed partition, grid storage, data resource, encryption data
