三级存储设备随机调度研究

Research of Random I/O Schedule of Tertiary Device in Massive Storage Management

随着信息时代的来临,世界上每时每刻都有大量的数据产生。因此有必要找到一种更加方便和有效的方式来管理这些海量的数据信息。为了解决海量信息管理中的数据存储问题,文章讨论了诸如磁带库、光盘库等三级存储设备在海量存储系统中的应用。另外,针对目前三级存储设备I/O调度算法的一些缺陷,提出了一种自适应的随机I/O调度算法来弥补这些缺点。

With the information era's coming,more and more data has been created in every minute.It's critical for people to have an efficient and convenient way to manage so much information.In order to provide an available method to store massive information,this paper discusses random I /O schedule of tertiary device,such as tape libraries,used in massive storage system.Due to disadvantages of present schedule algorithms ,the paper suggests an adaptive schedule to mend such defects.
