数据中心虚拟化在服务器虚拟化的基础上,整合和抽象数据中心全部IT资源,构建数据中心虚拟化资源池,集中管理和统一调度,实现资源动态伸缩和业务的“弹”和“飘”。VMware ESX server是当前服务器市场上最流行的虚拟软件产品。对比其他虚拟软件产品,最大优点就是可以大大减少host系统所占用资源的,且产品稳定性经受了长期的考验。ESX server内核直接运行在硬件之上,而且系统稳定性和性能都有很大的提高。以下从技术理论结合实践经验,描述了虚拟化数据中心的一些优化方法。
Data center virtualization Based on server virtualization, it integrates and abstracts all the IT resources of the data center, builds the data center virtualized resource pool, centrally manages and uniformly dispatches resources to achieve dynamic scaling and service, With the wind". VMware ESX server is the most popular virtualization software product on the market today. Compared to other virtual software products, the biggest advantage is that you can greatly reduce the host system resources occupied, and product stability has withstood the long-term test. ESX server kernel runs directly on the hardware, and system stability and performance have greatly improved. The following combination of technical theory and practical experience, describes some of the virtualization data center optimization methods.
