摘要
指挥信息系统(C4ISR)是以计算机为网络核心,具有指挥控制、侦察情报、预警探测、通信、安全保密、信息对抗等功能的军事信息系统,而上述功能的实现都是以数据为基础的。文章针对指挥信息系统中数据存储技术的应用,讨论当前比较流行的3种数据存储技术:直接连接存储(Direct-attached storage,DAS)、网络附加存储(Network attached storage,NAS)和存储局域网(Storage area network,SAN),分析了各自在存储性能上的优劣,并通过实例说明其应用范围。
Command information system is a computer network core, with command and control, reconnaissance, early warning and detection, communications, security, information warfare and other functions of military information systems. All these functions are based on data storage. Three popular network storage technologies DAS SAN NAS are discussed. Their respective advantages and disadvantages in the storage per- formance are analyzed. The applications of the technologies are illustrated through examples.
