摘要
异地双活数据中心是现在传统大型数据中心的发展趋势。针对国内某民航旅客服务信息系统高并发在线交易、大规模海量数据处理、应急响应和灾难快速恢复等要求,提出一种基于球面Voronoi图的异地双活数据中心服务区域划分方法。该方法考虑了数据中心最大负载量的受限性和所有被分配用户访问到各自数据中心的总距离最小化,并在求解过程进行了双曲化优化逼近和用户分布估计。实验结果表明,在不同访问用户条件下,该方法都能重新调整用户访问数据中心的接入点,给出合理的区域划分。该方法能均衡单数据中心的系统访问压力,为大数据时代数据中心建设和灾备系统建设提供技术支持。
Distant double live data centre is nowadays the development trend of traditional large data centres. According to the requirements of a certain China＇ s civil aviation passengers information service system, which includes highly concurrent online transactions, large-scale mass data processing, emergency response and quick disaster recovery, the paper presents a service region divistion solution for distant double live data centre, which is based on Voronoi diagram on the sphere. This solution takes into consideration the property of data centre＇ s peak load being constrained and the minimising of total distance that all the assigned users accessing to the data centre of each own, and makes hyperbolic optimised approximation and users＇ distribution estimation in calculation process. Experimental results show that whatever the users＇ access is, this scheme can all readjust the access points of users when accessing the data centre, and offers reasonable region division. The scheme can balance the system access pressure of single data centre, and provides technical support for the construction of data centre and disaster recovery system in big data era.
