针对当前计算机存储系统结构中存在的若干问题,文中提出了一种新型的智能网络磁盘(Intelligent Network Disk,IND)存储系统结构.分别给出了IND内部数据的读/写控制、容错处理、负载平衡等智能控制算法,已经构建了一个IND结构的模拟原型IND存储系统.IND存储系统中各个IND都是直接与网络连接,若干个IND组成一个集群存储系统,给用户提供了一个虚拟化的海量存储系统.另外,由于各IND都具有一定的智能度,所以它是一种灵活可变的智能型网络存储器系统.
In this paper, some problems on storage system architecture of computer network are analyzed, a novel storage system architecture of the Intelligent Network Disk(IND) is presented. The internal read and write control algorithms, the tolerant-fault strategies, and the workload balance algorithms for the IND storage system, are all described in detail. Also a basic experimental system of the IND storage architecture has been constructed. Since each IND of the IND storage system is linked directly to the high LAN, some INDs can form a network cluster of stor- age system. And, it will provide a virtual huge storage system for users. In addition, as each IND has some intelligence, the IND storage system is a flexible Intelligent Network Storage System.
