基于大二层技术实现云资源池异地容灾

Achieving Remote Disaster-Tolerant of Cloud Resource Pools Based on the Large-scale Access Layer Technology

文章首先全面分析了基于大二层技术实现云平台跨资源池异地容灾的条件。然后阐述了为实现云平台业务异地容灾的目标,如何通过网络和云平台对网络汇聚层交换机进行OTV的部署、调试及配置工作。最后对云平台虚拟机跨资源池迁移进行对比分析,为迁移问题的排查和业务系统的异地容灾提供指导,同时为今后进一步优化提供方向。

Firstly,this paper comprehensively analyzes the conditions of achieving remote disaster-tolerant of cloud platform across resource pools based on the large-scale access layer technology.Secondly,in order to achieve the goal of remote disaster-tolerant of cloud platform business,it expounds how to deploy,debug and configure the OTV to the network convergence layer switch through network and cloud platform.Finally,the cross resource pools migration of cloud platform virtual machines are compared and analyzed to provide guidance for the troubleshooting of migration problems and remote disaster-tolerant of business systems,and provide direction for further optimization in the future.
