多硬盘视频存储器的设计与实现

Design and Realization of Multiple Hard Disk for Video Storage

文中设计并实现了一个多硬盘存储系统 ,可同时挂接 1 6个普通IDE接口的硬盘。该系统采用ATA 4规范 ,单个硬盘的最大容量可达到 1 37G。在安防行业按照 4 5 0M/小时的视频存储速率 ,该系统可供一个录像系统连续录像 4 80 0小时。如果利用现有的硬件设备 ,则该系统无需增加额外成本 。

This paper introduces a multi HDD system based on normal IDE interface is designed and implemented. This system can accommodate sixteen HDD simultaneously. For ATA 4 standard, the single HDD capacity can be up to 137G. In surveillance business, for a given video data rate 450M/hour, this system can support a recorder to record more than 4800 hours continuously. By adopting the existing hardware, the system does not need additional cost, and its stability has been proved in practice.
