摘要
以湖南图书馆为例,详细论述了如何在不对现有应用模块及支撑其运行的逻辑架构环境做变动的前提下,通过主机系统虚拟化技术实现绝大部分应用模块底层架构平台的统一;如何采用源端去重、窄带传输这种全新的备份方式实现全省数字图书馆平台的异地灾备,最终结合主机、存储虚拟化及IP SAN技术实现各馆关键业务数据的异地实时同步;以及如何同时利用各馆剩余资源建立异地容灾中心,真正实现全省数字图书馆的永不打烊。
Taking Hunan Library as an example,this paper mainly discusses how to achieve the unity of the underlying architecture platform for most of the application modules through the host system virtualization technology under the precondition of no doing changes on existing application modules the logic architecture environment supporting its operation;how to realize the remote backup and disaster recovery of whole province＇s digital libraries by using source-side deduplication and narrowband transmission,a new backup way,and finally realize the off-site real-time synchronization of each library＇s mission-critical data combining the host computer,storage virtualization and IP SAN technology;and how to really realize the never closing of whole province＇s digital libraries through establishing the remote disaster recovery center by using the remaining resources of each library at the same time.
