0引言随着虚拟化技术在省级数据中心的推广和应用,越来越多系统的运行不再依赖于独占的硬件资源,而是以共享硬件资源的方式运行于虚拟化平台之上。虚拟化平台集中共享硬件资源的方式能够实现服务器整合,为应用系统提供独立、高效和灵活的运行环境,同时节约资源,方便管理[1],但会对与虚拟化平台安全稳定运行密切相关的网络共享存储提出更高的要求。某银行中心支行(以下简称“该中支”)以所辖省级数据中心虚拟化平台为应用场景,基于DRBD和Pacemaker等开源技术搭建了一套可用的网 0 Introduction With the popularization and application of virtualization technology at the provincial data center, more and more systems run no longer depend on exclusive hardware resources, but operate on the virtualization platform by sharing hardware resources. Virtualization platform centralized way to share hardware resources server consolidation can be achieved for the application system to provide an independent, efficient and flexible operating environment, while saving resources and facilitate management [1], but will be safe and stable operation of the virtualization platform is closely related Network shared storage put forward higher requirements. A bank central branch (hereinafter referred to as “the branch ”) under the jurisdiction of the provincial data center virtualization platform for the application of the scene, based on open source technologies such as DRBD and Pacemaker to build a set of available network
