基于虚拟平台的虚拟化存储的设计与实现

Design and implementation of virtual storage based on virtual platform

目的:研究VMware存储虚拟化技术,解决现有虚拟平台存储存在单点故障、磁盘阵列老化、服务器性能不足等问题,以优化医院虚拟平台的架构。方法:利用存储虚拟技术即VMware软件定义存储概念及方法,实现软件数据中心的服务器、存储虚拟化,更新现有平台硬件设备,对虚拟化存储进行设计。结果:实现了服务器存储容量的在线扩增,降低了系统的管理难度,在提高系统性能的同时,消除了原有平台信息存储单点故障的问题,保障了系统的高可用性。结论:虚拟化存储技术是具有高可扩展、高灵活度、高安全性的信息基础架构,完全满足未来医院业务发展需求,值得推广应用。

Objective To study VMware storage virtualization technology to optimize hospital virtual platform in single-point failure, disk array, server performance and etc. Methods VMware software was used to define the concepts and methods for storage, virtualize the server and storage, update the hardware equipment in the platform and design virtual storage. Results On-line data capacity extension was executed for the server, and the difficulty was relieved in system management. The system availability was enhanced by increasing the system performance while eliminating single-point failure in information storage. Conclusion Virtual storage technology gains advantages in high extensibility, flexibility and safety, and thus is worthy promoting in futural hospital practically.
