基于云计算的虚拟化PXE技术在计算机实验室中的应用

Application of virtual PXE technology based on cloud computing in the laboratory

为提高计算机传统存储设备的充分利用、实现开源节流;同时解决计算机实验室在软件优化升级过程中由于网络环境不稳定而引起数据不间断丢包,造成系统不完整而发生故障,本研究提出基于云计算的PXE技术搭建虚拟工作站方案,加速高校计算机实验室的转型升级。测试结果表明:该方案中的虚拟化PXE技术能减少实验室存储设备投资,优化计算机实验室的整体性能,管理维护便捷,提高了数据安全性,系统扩展性良好,降低了硬件报废率,缓解了目前教学设备的压力,从而降低实验室维护成本、硬件成本及人员工作量。本研究除了可应用于高校计算机实验室,在大中小型公司、企事业单位、营业厅等场景也具有很好的应用价值。

In order to improve the full utilization of traditional computer storage devices and achieve open source and throttling,while solving the problems of uninterrupted data packet loss and system failure caused by unstable network environment during software up-grade in computer laboratories,cloud computing based PEX technology is used to build virtual workstations and accelerate the transforma-tion and upgrading of university computer laboratories.The test results show that this technology can reduce investment in laboratory stor-age equipment,optimize the overall performance of computer laboratories,facilitate management and maintenance,improve data security,have good system scalability,reduce hardware scrap rates,improve the current pressure on teaching equipment,and thereby reduce labo-ratory maintenance costs,hardware costs,and personnel workload.This solution not only can be applied to computer laboratories in uni-versities,but also has good application value in scenarios such as large,medium,and small companies,enterprises,and business halls.
