基于网格的数字图书馆分布式资源存储模型分析

The Analysis of the Digital Library Distributed Resources Storage Model Based on the Grid

基于网格的资源存储采用存储虚拟化、简化存储管理等模式,具有高可用性、可管理性、可扩充性和高安全性等优势,能全面有效地解决数字图书馆的资源存储问题。同时,为了构建数字图书馆分布式资源网格存储应用模型,提出了存储空间管理、元数据目录服务、副本管理、备份管理等功能模块设计。

The storage resources based on the grid adopts the storage virtualization and simplified storage management mode, have advantages of high usability, manageability, scalability and high safety, which can solve the problem of the digital library resources storage effectively. And in order to establish the distributed resources storage application model of the digital library based on the grid, the article puts forward the design of several key function modules, such as the storage space management, metadata directory services, copy management, backup management and so on.
