【摘要】 模拟系统是研究与测试系统功能的重要方法,分析了现有存储区域网模拟系统,针对测试各类应用于保护存储区域网系统的安全机制,设计了开放式安全存储区域网模拟平台.使用线程模拟存储区域网系统中的主机、元数据服务器和存储设备,使用缓冲区模拟存储区域网系统中的通信,实现了接收访问请求和主机模块,构建了元数据和存储设备模块的框架,提供了实现元数据管理和存储设备中数据管理功能的功能接口,能模拟存储区域网的各项功能;在元数据和存储设备模块中提供了增加安全保护机制的安全接口,通过实现的不同安全保护机制,能模拟各类安全存储区域网系统,从而为测试各类应用于保护存储区域网系统的安全机制提供良好的平台;最后在元数据和存储设备模块中,通过功能接口实现了基本的元数据管理和存储设备中的数据管理功能,测试系统是否能正确地处理访问请求,完成存储区域网的功能.测试结果表明:开放式安全存储区域网模拟平台能模拟存储区域网处理访问请求的流程,为测试各类应用于保护存储区域网系统的安全机制提供了良好的基础.更多还原

【Abstract】 Simulator is an important method for researching and evaluating systems.Firstly some current simulators of storage systems are analyzed.Then the structure of open secure storage area network simulator is designed based on the demands of secure storage area network systems.Thread is used to simulate client,metadata server and disk in storage area network systems.Buffer is used to simulate communication in storage area network systems.The simulator of open secure storage area network contains four modules:receiving access request,client,metadata server and storage device. There is a function interface to stimulate the metadata and data management in metadata server module and storage device module.And there is a security interface to stimulate the secure strategy in secure storage area network systems.Then the function interface in metadata server and storage device modules is implemented to stimulate the process of dealing with the access request,and evaluating simulator.Finally the result shows it can simulate the flow of dealing with the access request in the storage area network systems and provides a good platform for evaluating and researching secure storage area network systems.更多还原
