摘要/Abstract

摘要： 存储系统已由NAS向SAN发展,如何融合NAS和SAN技术,提高存储系统的可管理性和性能,是目前存储领域研究的热点。提出了一种扩展文件共享的方法,采用三方传送机制来融合NAS和SAN,通过存储管理器和存储服务器的功能划分,由存储管理器负责存储设备的空间和文件的管理,存储服务器能共享SAN中的存储设备以及直接访问存储设备上的数据。该系统采用Lease协议来保证存储服务器端数据一致性,在此基础上分析了Lease协议模型。

Abstract: Storage system has evolved from NAS to SAN,how to blend the technology of NAS & SAN,and how to improve manageability and performance is hot point problem of storage field.This paper presents a method for extent file-shared to blend NAS and SAN,by partition the function of storage manager and storage server,the space and files of storage device are managed by storage manager,data on storage device can be shared by storage servers.Lease protocol is used to ensure data consistent on storage servers.Furthermore,this paper analyzes Lease protocol model.

Key words: third-party transfer, storage management, lease, storage area network
