摘要：

针对容灾信息系统难以量化和评价的问题,提出了一种通用的容灾信息系统建模方法,设计并实现了容灾仿真系统. 基于网络3层架构模型构建了系统仿真模型,采用故障注入技术实现了灾难事件仿真,并基于脚本编程实现了容灾信息系统运行过程仿真. 设计了仿真一致性、恢复时间目标、恢复点目标和可用存储量指标实现对仿真系统的评价. 实验结果表明,容灾仿真系统满足设计目标,能够为信息系统灾备建设、容灾信息系统灾难恢复能力评价和系统维护提供数据支撑.

关键词: 系统仿真, 系统容灾, 灾难备份, 故障注入

Abstract:

Focused on the issue that it is hard to quantify and evaluate a disaster tolerant information system, a general modeling method for the disaster tolerant information system was proposed. A disaster tolerant simulation system (DTSS) was designed and implemented. A general disaster tolerant simulation system model was put forward upon three-tier network architecture model, and fault injection technology was made to simulate the disaster events. Furthermore, system business simulation is carried with script programming. Simulation consistency, recovery time object, recovery point object and available storage indices were designed to evaluate the system. It is shown that the disaster tolerant simulation system can provide data service for disaster system construction of the information system, disaster recovery ability evaluation of the disaster tolerant information system, the system maintenance.

Key words: system simulation, system disaster tolerance, disaster backup, fault injection
