| 摘 要： | 建立了一个四层文件系统,将来自多个通道的采样数据按存储任务编号、通道号、采样起始时间分层存储,并对每层数据提供相应的索引文件,提供了按通道号及时间段的快速查询服务。测试表明,在IBM服务器上达到了150 MB/s的存储速度,可以满足同时300个通道的实时采样数据存储任务。

| Abstract: | A 4-layer file system was established to store the sampling data from multiple channels into several layers based on storage-task ID,channel ID and sampling start time.The ability of fast que-rying by channel ID and sampling time interval was provided by using the index file in every layer.As a result of the experiment,the storage speed can achieve 150 MB/s on the IBM server,which can sa-tisfy the requirement of real-time storage of sampling data from 300 channels. |
