Design of high-speed storage system based on multi-channel sampling data
Wei Jun · Journal of Naval University of Engineering · 2008
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.
