关于服务器系统虚拟化技术综述

Summary of Server System Virtualization Technology

近些年计算机硬件资源不断升级,计算机的计算性能得到了极大提高,传统单一的I/O系统已经无法满足硬件资源的需求;因此,系统级虚拟化技术被广泛应用于大型服务器系统,从而有效提高了计算机的整体性能。笔者总结了系统级虚拟化按照硬件资源的分类、I/O系统级虚拟化的特点、国内外研究现状及发展趋势,从三个角度全面解读I/O系统级虚拟化技术。

In recent years,with the upgrading of computer hardware resources,computer computing performance has been greatly improved.Traditional single I/O system has been unable to meet the needs of hardware resources.Therefore,system-level virtualization technology is widely used in large-scale server systems,thus effectively improving the overall performance of the computer.The author summarizes the system-level virtualization according to the classification of hardware resources,the characteristics of I/O system-level virtualization,the research status and development trend at home and abroad,and comprehensively interprets the I/O system-level virtualization technology from three perspectives.
