摘　　要：H3C CAS云计算管理平台为H3C公司推出的统一虚拟化管理平台,目前很多企业采用此虚拟化平台来实现虚拟机的创建与管理,进而提高企业计算资源的管理效率。为了在H3C CAS平台上实现云主机高可用的特性,采用基于因特网的小型计算机系统接口(Internet Small Computer System Interface,iSCSI)存储架构进行共享存储,将创建虚拟机的镜像文件和虚拟机磁盘文件保存在共享存储磁盘上,以应对某些突发情况导致虚拟机所在主机宕机造成虚拟机响应中断的情形。通过VMware Workstation软件搭建云计算管理平台(Cloud Automation System,CAS),并使用iSCSI作为共享存储架构进行仿真实验。实验结果表明,iSCSI共享存储方式可以延长虚拟机的平均故障间隔时间,提升用户体验。H3C CAS cloud computing management platform is a unified virtualization management platform launched by H3C Company.At present,many enterprises use this virtualization platform to create and manage virtual machines,thus improving the management efficiency of enterprise computing resources.In order to realize the high availability of cloud hosts on H3C CAS cloud computing management platform,the Internet Ssmall Computer System Interface(iSCSI)storage architecture is adopted for shared storage,and the image files and disk files of the created virtual machines are saved on the shared storage disks,so as to cope with the situation that some unexpected situations cause the host where the virtual machines are located to be down and the virtual machine response is interrupted.Cloud Automation System(CAS)platform is built by VMware Workstation software,and iSCSI is used as the shared storage architecture for simulation experiment.The experimental results show that iSCSI shared storage can prolong the mean time between failure of virtual machines and improve the user experience.
