The work in this thesis was part of a national 05 " project which task was designing the " longtengrl " microprocessor . there are four parts in " longtengrl " microprocessor : integer execution unit ( ieu ) , floating point unit ( fpu ) , memory subsystem unit ( msu ) and bus interface unit ( biu ) 本论文完成存储子系统单元的设计与实现、 “龙腾r1 ”系统的集成、存储子系统单元的验证以及在“龙腾r1 ”存储子系统基础上进行了tracecache的研究，其中重点讨论存储子系统的设计与实现。
The work of system is divided into two part , one is communication with manager agent of storage subsystem in agent / manager pattern , acquiring and processing performance information of storage subsystem ; the other is communication with browser in server / client pattern , providing performance & optimization information to browser , corresponding user command and output performance log file 系统的工作方式分为两部分，与存储子系统内管理代理通信，获取性能情报并对性能情报加工、处理；与用户browser通信，提供实时性能数据、优化数据并响应用户命令，同时定期输出性能日志文件。
Performance & optimization manager is key component of san storage resource management system . it is used to execute performance surveillance , performance analysis and overload balance of storage subsystem in shared storage architecture , ensure storage subsystem in order and develop the potential of storage resource so as to enhance the performance of total shared storage architecture 性能监视和优化服务是san存储资源管理的重要组成部分，它主要用于san共享存储体系中存储子系统的实时监控、性能分析、均衡负载，保证存储子系统的正常工作，挖掘存储资源潜力，进而提高共享存储体系的整体性能。
