摘要:

以VMware虚拟化平台在性能密集应用场景下的性能设计、优化管理为目的,结合笔者多年的操作经验,总结出虚拟化平台性能设计要点和优化方法,希望对医疗行业广大读者在虚拟化技术应用方面有所帮助。阐述了利用vCenterServer管理界面中的“性能”视图和esxtop性能分析工具,结合虚拟机操作系统中的性能监控工具来分析虚拟化平台的整体性能负载情况,并针对性地提出优化建议来改善虚拟化整体环境的合理性,对于虚拟机系统资源不足或过度分配的情况进行调整,其目的是在保障应用系统性能的情况下更加合理、高效地使用有限的资源。通过规范的设计和调整,有效地提升了虚拟机的性能和业务连续性,以及整体虚拟化平台的利用效率和使用水平。

Abstract:

For the purpose of the performance design, optimization and management of VMware virtualization platform in the performance intensive application scenario, combined with years of operating experience, the author summarizes key points for performance design and optimization methods of the virtualization platform, shares experiences with users of the virtualization platform, and hopes to help readers of the medical information industry with the virtualization technology applications and improve the medical information management and service level. This paper explains how to analyze the overall performance and load of the virtualization platform with the "performance" view and esxtop performance analysis tools in vCenter Server management interface combined with the performance monitoring tools in the virtual machine operating system, and gives corresponding optimization suggestions to improve the rationality of the overall virtualization environment, and adjusts for insufficient virtual machine system resources or excessive allocation. The purpose is to guarantee the performance of the application system, and use limited equipment resources in a more reasonable and efficient manner. Through standard design and adjustment, and turning on the hot add function of CPU and memory of the virtual machine, the performance and business continuity of the virtual machine and the efficiency and use level of the overall virtualization platform can be enhanced effectively.
