Abstract新疆天文台南山26m射电望远镜(简称NSRT)经过多年观测积累了大量的科学数据。针对NSRT天文观测数据的在线存储与备份问题,建设了远程、异地、容灾备份系统,在新疆天文台本部及南山观测站分别建设了可独立运行的存储系统,实现了两套存储系统间的远程、异地数据实时容灾备份。以基于对象的存储技术Lustre为基础实现了存储系统,并对存储的读写性能进行了详细测试。建设的容灾备份系统有效解决了新疆天文台观测数据及次生数据的在线存储与数据安全问题。
Other AbstractAfter years of observation, Xinjiang Astronomical Observatory (XAO) Nanshan 26 meters radio telescope(NSRT) had accumulated massive scientific data.A remote backup system was established for the online data storage of NSRT, this redundant storage system contained two storage clusters, one cluster was in XAO headquarters and the other located in Nanshan station, the real-time synchronization of NSRT data could be realized between two storage clusters. Based on the object storage technology, centralized cluster storage system was created for storage clusters, and the I/O performance test of luster systems was finished. Redundant storage system solved the online archive and data safety issue for NSRT data.
