随着信息资源和数字资源类型增多,校园网络建设面临如何存储和管理这些数字资源的问题。本文介绍了湖南师范大学存储系统实施经验。从SAN管理、数据分级存储、数据生命周期管理三个方面着手,讲述了如何设计存储架构以及基于该体系结构下的海量信息的管理流程与算法。 With the increase of types of information resources and digital resources, campus network construction faces the problem of how to store and manage these digital resources. This article introduces the implementation experience of Hunan Normal University storage system. It starts from three aspects of SAN management, data hierarchical storage and data lifecycle management, and describes how to design the storage architecture and the management processes and algorithms based on the massive information under the architecture.
