Design and Realization of E-Learning Resource Storage System


Article Preview

The datacenter of one university owns massive E-Learning resources, and how to support safe and efficient access so as to support large-scale concurrent read and write protection has troubled the administrators of the campus datacenter. In this paper, we presented our E-learning resources storage system. The resources are stored in one HDFS(HADDOP Distributed File System) based storage systems, to effectively support the E-learning scenarios as small write-once files with large-scale concurrent read scenarios. Within the System, the E-learning data can be deployed redundantly across multiple storage nodes, which are distributed so as to improve read and write speed. Furthermore, when a single data node fails the system can also be recovered by redundant node data in the system and improve system security greatly. The system supports that the desktop systems, mobile platforms and web browser can access the system with cross-platform mechanism. The system adopts encryption mechanisms through the establishment of secure storage directory, and the user terminal can encrypts and unencrypts the user-files with offline mode to guarantee the safety of user data.
