基于气象业务零中断的存储数据迁移探讨研究

在广东省气象局2015年建设高性能存储设备逐渐老化，厂商即将停止设备技术支持服务背景下，针对存储所承载的气象业务系统面临着数据丢失或业务中断的风险问题，结合气象业务具有时效性、连续性等特点，通过运用异构迁移技术，对新存储建设要求、数据迁移原则、存储规划、风险评估、回退方案、数据迁移进行探讨研究，实现50多个核心关键业务系统的430TB数据在82小时完成平稳迁移，数据迁移速度最高达2.1GB/秒，平均速度1.5GB/秒，相比在应用层上做数据迁移的传统方法，异构虚拟化迁移技术具有迁移速度快、时间短、工作量少、业务无中断和可集中迁移的特点。

Research on storage data migration based on zero interruption of Meteorological Service

Under the background that the construction of high-performance storage equipment by Guangdong Meteorological Bureau in 2015 is gradually aging and the manufacturer is about to stop the equipment technical support service, in view of the risk of data loss or business interruption of the meteorological business system carried by the storage, combined with the timeliness and continuity of meteorological business, through the use of heterogeneous migration technology, the requirements for new storage construction, data migration principles, storage planning, risk assessment Discuss and study the fallback scheme and data migration, and realize the smooth migration of 430tb data of more than 50 core key business systems in 82 hours. The data migration speed is up to 2.1gb/s, with an average speed of 1.5gb/s. Compared with the traditional method of data migration at the application layer, heterogeneous virtualization migration technology has the characteristics of fast migration speed, short time, less workload, non-stop business and centralized migration
