虚拟桌面技术实施和运维过程中的优化策略

The Optimization Strategy in Implementation and Operation of Virtual Desktop Technology

随着高校多媒体教室、计算机机房规模的不断扩大,传统的运维管理方式已很难适应现代计算机教学与考试的要求,许多高校采用了虚拟桌面来取代旧的运维方式.以幻影(Phantosys DVP)和江波(PNS Quick Desktop)虚拟桌面产品为例,探索虚拟桌面项目实施和运维过程中的优化策略:对教室和机房进行网络优化和桌面集中化管控;合理配置服务器数量,对服务器进行链路聚合拓展带宽,及时备份重要数据;制定满足实际需求的客户端磁盘分区策略;掌握处理客户端磁盘故障和重建数据缓冲区的技巧;提高镜像的重用性和可移植性,灵活利用镜像保护与开放模式的切换;采取适当的桌面安全策略.运维工作者通过这些优化策略,可提高工作效率,减少设备故障,降低运维成本.

With the continuous expansion of multimedia classrooms and computer rooms in universities, it isdifficult for the traditional operation and maintenance methods to adapt to the requirements of modern teaching andexamination by computer. Many universities have applied virtual desktop to replace the old operation andmaintenance method. Taking Phantosys DVP and PNS Quick Desktop virtual desktop products as examples, thispaper explores the optimization strategy in the implementation and operation of virtual desktop project, such ascarrying out network optimization and desktop centralized control for classroom and computer labs, configuring thenumber of servers according to the real demand to save energy consumption, extend the link aggregation bandwidthto the server and backup important data in time, developing a client disk partition strategy that meets the actualneeds, mastering the skills of handling client disk failures and rebuilding data buffers, improving the reusabilityand portability of system image, using the image protection and open mode switching flexibly for different needs,and adopting appropriate desktop security policies. Through these optimization strategies, operators can improvework efficiency,reduce equipment failures, decrease operation and maintenance costs.
