摘要
为了解决在使用开源软件构建云存储平台的过程中,可能会面临的各种实际问题,比如存储集群的高可用、超大规模节点集群部署和维护、跨多数据中心解决方案等等。我们采用了诸多技术手段,如增加前端数据缓存、预备份数据来提高处理效率;通过增强数据冗余检查、数据的一致性检测保障数据安全,加强了健康检查和告警模块、自动化部署、优化通知和轮询机制,增强了网络监测技术来实现便捷的运维管理。我们通过将所有存储组件都多活热备,各种相同功能的组件高可用分布到不同机架,来达到提高产品可用性的目的。
For a long time,the core technology of storage equipment,such as SAN and NAS,belongs to some largeenterprises abroad,in order to break this situation,and get involved core storage technology,our teamfrom China Mobile conducted in-depth research and extensive practice.Use open source software,suchas Ceph,as a technical basis,engineers can be more convenient and quick to cut into the storage areas,which technology is believed not easy to master.This article is to solve the practical problems that maybe faced in the process of building a cloud storage platform using open source software,for example,high availability of storage clusters,deployment and maintenance of ultra-large-scale nodes,cross-datacenter solutions,and so on.We have adopted a number of technical means,such as adding front-enddata cache,pre-backup data to improve processing efficiency;by enhancing data redundancy checks,data consistency detection to protect our data,enhancing health check and alarm module,automateddeployment,optimizing the notifi cation and polling mechanism,and enhancing the network monitoringtechnology to achieve convenient operation and maintenance management.We are able to achieve thegoal of improving product availability by distributing all the storage components in a variety of racks ofthe same function.
