摘要
我国地震监测系统历经了数字化、网络化和自动化的变革.随着地震监测站网规模的不断扩大,作为国家数据中心,中国地震台网中心面临数万地震台站观测数据处理和存储压力.本文基于前期国家地震烈度速报与预警工程、公共安全信息化工程(中国地震局)建设项目等建设经验,总结地震数据分布式存储系统的建设模式,并验证其合理性.同时以历史数据迁移归档业务为例,分析共享存储系统的服务效能,为海量观测数据的高效存储管理、共享数据存储系统建设提供参考.
Abstract
Earthquake monitoring system of China has experienced the innovation of digitalization,cyberization and automation.With the expansion of earthquake monitoring station and network,China Earthquake Networks Center(CENC),as the national earthquake data center,is facing serious pressure of processing and storing data from tens of thousands of earthquake monitoring stations.This paper mainly focuses on the key points in constructing the distributed storage system based on experiences from Earthquake Early Warning Project and Public Security Information Project(CEA subproject),and trying to demonstrate its advantage and rationality.This paper also analyzes the service capacity of shared server system with the case example of history data transfer and archive business.The results of this paper will provide further reference for the storage and management of mass earthquake data efficiently and the construction of shared data storage systems in different departments.
