Optimizing the performance of cloud storage is very important for Internet development. This paper presents the performance evaluation of the open source distributed storage system, a highly available, distributed, eventually consistent object/blob store from Open Stack cloud computing components. This paper mainly focuses on the mechanism of cloud storage as well as the optimization methods to process different sized files. This work provides two major contributions through comprehensive performance evaluations. First, it provides different configurations for Open Stack Swift system and an analysis of how every component affects the performance. Second, it presents the detailed optimization methods to improve the performance in processing different sized files. The experimental results show that our method improves the performance and the structure. We give the methods to optimize the object-based cloud storage system to deploy the readily available storage system.展开更多

文摘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。
