一种简易IDE RAID在高速数据采集系统中的应用

Simple IDE RAID used in high-speed recording system

提出了一种使用普通IDE硬盘构成简易冗余硬盘阵列(redundantarrayofindependentdisks,RAID)磁盘阵的实现方法,并将其应用于自行开发的基于PCI总线的高速数据采集系统中,实现对高速采集数据的实时存储。该方法与传统的SCSI硬盘组成的磁盘阵相比,结构简单、成本更低,而数据写入速度却可以接近SCSI磁盘阵的性能,可以满足高速采集系统的写入速度要求。

A realization method of simple RAID array using an ordinary IDE disk is presented and then applied to the Self-developed high-speed data-recording system based on PCI to achieve the real-time recording. Compared with conventional SCSI disk RAID array the given method is of simple structure, low cost, performance approaching that of SCSI array in terms of data recording speed, and recording speed satisfying the demand of a high-speed recording system.;
