摘　　要：设计并实现了基于WDM的磁盘I/O Trace的收集器。它基于扇区级别,能够监测硬盘上哪些扇区频繁访问,并将这些信息保存在日志文件中,分析这些保存的信息,找出一些规律,将频繁访问的数据保存在快速存储器,达到提升性能的目的。该收集器可应用于网上点歌系统、视频点播系统中,能够提供更好的服务。WDM-based disk I/O Trace collector is designed and implemented. It is according to an area class, can monitor the hard drive up which interview with multifarious area, and keep this information in the daily record document. Then, this information is analyzed, and some regulations are found out. The data of multifarious interview can be kept in the fast saving machine, so as to promote the function. This disk I/O Trace collector can be applied in on-line song system and VOD system, and it can provide better service.
