磁盘冗余阵列技术解析

Tchnological analysis of redundant array of disks

采用磁盘冗余阵列(Redundant Array of Disks 简称 RAID)技术存储数据,可以实现不同等级的冗余和错误修复。RAIDO 只是简单地增加了存储的容量和数据的操作速度,RAIDI 实现了数据的镜像备份,RAID3则具有效据的检错和纠错功能。各种 RAID 技术的结合是一个符合服务器大容量硬盘、数据安全性和服务器运行速度等综合要求的廉价解决方案。

The adoption of the redundant array of the magnetic disc (Redundant Array of Disks is abbreviated as RAID) can realize the different grade redundantce and error recovery.RAID0 has simply increased the speeds of the operation and the capacity of the memory.RAID1 can realize the data copy of the mirror image.RAID3 can examine the mistakes and correct them.The combination of the different RAID technology is a low-priced solution in raising data security and server running speed and heavy capacity of hard disks.
