Abstract: As the technology of “Two Width and One Height” in petroleum exploration applied in depth, it makes a higher demand for seismic data parallel processing capacity, this paper focuses on the impact of storage on seismic data processing applications. To improve the efficiency of various types of applications, it designs and implements multi-level hierarchical storage for seismic data processing method based on SSD and cluster NAS, which designs algorithm flow for high IOPS applications and parallel applications contain large data block. It proves that the design has the advantages of application efficiency and cost performance in seismic data processing, which uses the DD and IOZONE benchmark test and two applications running result. The design is suitable for the seismic data processing of the exploration data center, and has certain universality.
