基于Citrix 虚拟化技术和PXE 无盘Linux 的局域网应用平台

分析公司Gartner最新研究结果显示,目前有超过80%的企业实施了虚拟化项目或者计划。Citrix公司的服务器虚拟化产品XenServer和应用虚拟化产品XenApp配合基于PXE远程引导技术的无盘Linux,不仅降低了局域网基础架构的复杂性,提高了局域网的运行效率,同时降低了局域网的软硬件成本,也可更方便地管理和维护客户端软件系统。     

基于XenDesktop桌面虚拟化网络平台的研究

Citrix公司推出的XenDesktop桌面虚拟化软件囊括了从虚拟底层硬件到虚拟应用程序的全部软件,它能将操作系统、应用程序和数据与底层的硬件系统分隔开。利用XenDesktop构建的整体虚拟化网络平台,解决了传统网络平台的软硬件费用高,架构复杂利用率低,管理、维护、升级困难,灾难和数据保护不足等缺陷。此外,其客户端可以通过局域网、互联网和无线网络进行访问,而且客户端本身也不再局限于传统X86 PC,MAC、平板电脑、手机都可作为客户端,实现了在任何位置、任何设备上进行访问的能力。     

The implementation of virtualization technology in EAST data system

The virtualization technology is very popular in many fields at present which has many advantages such as reducing costs, unified management, mobile applications, cross platform, etc. We have also implemented the virtualization technology in EAST control and data system. There are primarily four kinds of technology providers in virtualization technology including VMware, Citrix, Microsoft Hyper-V as well as open source solutions. We have chosen the Citrix solution to implement our virtualization system which mainly includes three aspects. Firstly, we adopt the XenServer technology to realize virtual server for EAST data management and service system. Secondly, we use XenApp technology to realize cross platform system for unify data access. Thirdly, in order to simplify the management of the client computers, we adopt the XenDesktop technology to realize virtual desktops for new central control room. The details of the implementation are described in this paper.
