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。
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 querying 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 satisfy the requirement of real-time storage of sampling data from 300 channels.
