The data storage system for SHINE

Abstract Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) is a quasi-continuous wave hard X-ray free electron laser facility, which is currently under construction. The data storage system holds large volumes of data generated instantaneously during the operation. A combination architecture of relational database, non-relational database and the distributed file system is designed as the centralized data storage system serving to multiple application demands for SHINE. The storage of high-speed stream data such as waveform and image data is studied and relevant storage schemas are tested and compared. The optimized schema is identified finally.
