摘要：

面向企业网或校园网的移动办公与存储的网盘系统有着广泛的市场需求，传统的网盘技术在性能、用户共享、安全性、可扩展性等方面存在诸多缺陷。针对这些不足，本文提出了一种基于云存储的高性能网盘系统架构：采用分布式文件系统MooseFS实现用户数据存储与访问的集群架构；在安全性方面，结合SAMBA实现用户权限管理，用户数据存储支持128bit AES加密，SSH保证了传输链路的安全；最后，结合用户的实际需求，提供基于Web的访问方式以及客户端的同步盘模式。结果表明，系统在性能、安全性、可扩展性等多方面具有显著优势。

Abstract:

Network disk for mobile office and storage in enterprise networks or campus networks has a broad market, however, the traditional technology has various limitations in performance, security and scalability. To address these issues, a solution based on cloud storage is proposed: by using the distributed file system MooseFS, all data servers are integrated into a cluster;in terms of security, user rights management is implemented by SAMBA, the storage supports 128 bit AES encryption, and the transmission link is protected by SSH; finally, the system provides both Web and client application modes for users. The experimental results reveal that the system has significant advantages in performance, security, scalability and other aspects.

Key words: network disk, cloud storage, distributed file system, cluster, user space
