基于安全预警技术的冗余磁盘阵列系统设计

Redundant Array of Independent Disks System Design based on Security Warning Technology

冗余磁盘阵列简称RAID技术,它是一种采用磁盘阵列方法提高磁盘访问速度、靠增加信息冗余量来提高数据安全性的磁盘存储技术,在小型计算机和服务器中广泛使用。文章针对磁盘阵列管理方式多样性的需求,对磁盘阵列预警技术进行了研究和分析,提出了基于安全预警技术的独立磁盘冗余阵列系统设计,增强了存储系统性能,提高了存储系统扩展性和可靠性。目前该技术已经开始移植到高档微机,并对微机存储体系结构的发展变化产生了非常重要的影响。

Redundant array of independent disks short as RAID, it is a disk storage technology which is used disk array to improve disk access speed, by increasing the amount of information redundancy to improve data security, and it is widely used in minicomputers and servers. This article researched and analyzed the needs of the diversity of the disk array manage- ment through the disk array early warning technology, proposed independent disk redundant array system design based on the security early warning technology, enhancing the storage system performance and improving the scalability and reliabili- ty of the storage system. At present this technology has been already migrating to high-end computer, and has made a very important impact on the development of microcomputer storage architecture.
