摘要
Abstract
When building a disaster tolerance system,the migration of large mounts of data will cause long time stagnation of local business.In addition,traditional disaster tolerance systems transmit data in the way of pushing,which results in an excess of local memory data accumulation.Aiming at solving these two problems,this paper designs and implements a dynamic disaster tolerance system based on storage virtualization.The system adopts techniques of dynamic image loading and asynchronous data transmission based on pulled-log.Test results show that,the system can render disaster tolerance service for the local without changing the local storage architecture,ensure data consistency and produce less than 20％ of the performance penalty.关键词
