优化的信息中心虚拟化实施方案

基于传统信息中心建设中存在的一些缺点，提出了一种基于vSphere架构的优化的信息中心虚拟化实施方案。相对于其他的虚拟化实施方案，本方案主要从可靠性和存储设备 I/O 性能两方面进行了优化。该方案从服务器、网络和存储设备等三个方面对系统可靠性进行了优化，分析了影响存储设备I/O性能的几大因素，并分别从是否采用多路径输入输出、Write-back cache写策略、磁盘I/O块大小、服务器性能等几个方面对系统I/O性能进行了优化。最后通过对整个系统的测试，验证了这一方案的优势。

Optimization Scheme of Information Center Virtualization

Based on the defects of traditional information center construction, this paper presents an implementation of virtual optimization vSphere architecture scheme based on informationcenter. Compared with other embodiments of virtualization, the scheme is mainly optimized from two aspects of reliability and storage I/O performance. The scheme optimizes the system reliability from three aspects of the server, network and storage equipment. It analyzes the influence factors of storage device's I/O performance. These factors are separately whether to use the multipath input and output, write-back cache write strategy, I/O disk block size and service performance etc. Finally, through the test of the whole system, we proved the advantages of the scheme.
