Application Of Storage Virtualization Integration And Optimization Technique In Seismic Data Management

In recent years,with the seismic data of processing and interpretation of the rapid development of technology,the data of processing and interpretation showed a massive growth in high-performance computing.The computing power of the large PC cluster processing and interpretation workstation is more demanding.The storage capacity is also higher requirements.The storage capacity must be able to adapt to the large-scale mass data storage requirements and challenges facing the high-speed data transmission.As the research topic,the high-performance computing and storage capacity of PC cluster computer and Interpretation workstation are improved through the application of dissimilar SAN,NAS centralized storage of data sharing technology.There are meet that the seismic data processing and interpretation of massive data storage needs.From both of the PC cluster architecture of SAN fiber storage system virtual integration of the processing center and NAS storage system integration of interpretation center in the Geophysical Research Institute starting,paper studies the virtual integration of the two systems of storage technology solutions.Eventually,through independent research and development program after the integration of the system,it is achieved that the processing and interpretation of the two systems SAN-NAS shared storage resource center.First,3 sets of PC cluster systems,four sets of TCP/IP network systems and seven sets of SAN storage systems of the processing center and interpretation center were achieved to integrate effectively through a number of new technologies,such as the SAN storage area network integration technology,high-end SAN storage systems virtual integration technology and PC cluster TCP/IP network integration technology.Thereby it was completed that the PC cluster architecture of SAN fiber storage system virtual integration of the processing center.A super-massive virtual storage system is built.The capacity to integrate the seismic data storage system storage reaches 560T.The three sets of NAS storage systems are integrated architecture to form a unified storage pool in the interpretation center through some own programs,such as "NAS storage system integration process" and "NAS storage system data sharing program".the capacity reaches 35.5TB.The 80 sets of interpretation workstations,servers,and NAS storage resource are shared.The NAS storage systems of interpretation center are integrated completely.Finally,the system of SAN-NAS shared storage resource center was constructed by applying the own "SAN-NAS storage resource sharing software".It is achieved to share that SAN-NAS storage resource of processing system and interpretation system.The seismic data of processing and interpretation can be done in parallel.The seismic data of processing and interpretation transfer more efficiently.The SAN-NAS storage systems are high-speed shared by large-scale PC cluster and interpretation workstations.The research results have been applied by the production and research of the seismic data of processing and interpretation in Daqing Geophysical No.1 company.Greatly the production capacity has been improved in some fields,especially in the three-dimensional pre-stack time migration and prestack elastic inversion.The production cycle has been shortened effectively.The Production have been improved efficiency and created significant economic benefits.
