浅谈域环境中网络计算机的应用作者:吴秋林来源:《科技与企业》2013年第12期【摘要】班组计算机的管理历来都是件头痛的事情,本文介绍了通过使用网络计算机结合域的控制可以很好地实现对班组计算机的管理控制。
并可以收到较好的经济效益,提高安全可靠性等。
【关键词】网络计算机(NC);域;管理控制;应用一、网络计算机简介网络计算机(Network Computer),简称为NC,也称瘦客户机。
它采用C/S(CLIENT/SERVER)工作模式,NC客户端没有配置硬盘,所使用的全部应用和数据都来自服务器,当NC远程登录到服务器以后,就像操作本地的PC机一样方便。
采用NC进行工作,所有的升级工作和管理维护工作均集中在服务器端。
近年来,由于应用系统的不断增加,班组计算机的数量也相应的有所增加,给维护带了一定压力。
为了更好地对班组计算机进行更好的管理。
公司在2010年采购了一台服务器和一批NC,为了保证NC用户的正常办公需求和以后的扩容,服务器选用了HP DL580,配置了8核2.7G CPU、16G内存和6*300G硬盘。
NC客户端则采用HP T5740w/Intel Atom N280/4GB闪存/1GB DDR3内存。
客户端采用远程连接服务器的方式,登录到服务器上进行相关操作。
在服务器上安装办公所需的全部应用系统和软件。
客户端也配置了4GB的闪存,在本端也可以进行网页浏览和一些简单的办公操作。
二、网络计算机部署及管理控制广东粤电云河发电有限公司早在2006年就建立了自己的内部域(YFPP),由于用户计算机并没有加入到域中,因而就不能对用户计算机进行统一管理控制。
为了较好地控制和管理客户端,给每个班组用户分配一个域账号,在服务器端设置远程连接的账户权限。
只有被授予了权限的班组才可以连接使用服务器上的资源。
在服务器上为每个账号分配一个私有空间用于存放资料,资料空间的大小可以根据实际所需进行相应的调整。
客户端连上服务器后可以使用服务器上所有安装的公用软件,并且访问自己的空间。

The device turns on and begins charging. TheCharging/Notification LED blinks amber while charging, then turns solid green when fully charged.The battery charges from fully depleted to 90% in approximately 2.5 hours and from fully depleted to 100% in approximately three hours. In many cases the 90% charge provides plenty of charge for daily use. A full 100% charge lasts for approximately 14 hours of use. To achieve the best charging results use only Zebra charging accessories and batteries. Charge batteries at room temperature with the device in sleep mode.Charging the Spare Battery1.Insert a spare battery into the spare battery slot.2.Ensure the battery is seated properly.The Spare Battery Charging LED blinks indicating charging. See Table 2 for charging indicators.The battery charges from fully depleted to 90% in approximately 2.3 hours and from fully depleted to 100% in approximately three hours. In many cases the 90% charge provides plenty of charge for daily use. A full 100% charge lasts for approximately 14 hours of use. To achieve the best charging results use only Zebra charging accessories and batteries.Table 2 Charging/Notification LED Charging IndicatorsTable 2 Charging/Notification LED Charging Indicators (continued)Solid Red Charging complete but the battery is at end of usefullife.Fast Blinking Amber (2 blinks/second)Charging error, e.g.:•Temperature is too low or too high.•Charging has gone on too long without completion(typically eight hours).Fast Blinking Red (2 blinks/second)Charging error but the battery is at end of useful life.,e.g.:•Temperature is too low or too high.•Charging has gone on too long without completion(typically eight hours).Charge batteries in temperatures from 5°C to 40°C (41°F to 104°F). The device or cradle always performs battery charging in a safe and intelligent manner. At higher temperatures (e.g. approximately +37°C (+98°F)) the device or cradle may for small periods of time alternately enable and disable battery charging to keep the battery at acceptable temperatures.

前一段时间测试的HP瘦客户机T5740由于存储介质是2G的Flash Disk,容量有限,厂家说可扩到16G,但是和硬盘比起来性价比太不高了,所以让他们换块硬盘来测试。
盒装东芝250G SATA硬盘已安装托架。
我和惠普的人员琢磨了好一会才安装好。
东芝250G SATA硬盘。
原来的Flash Disk 2G容量太小
只有虚线区域才能放下硬盘,用螺丝反着固定在金属机壳上。
这样一来势必硬盘盒电容、内存挨得特别特别近。
散热??
固定硬盘前,先卸掉1个VESA孔座,用钳子一敲OK。
线缆是一体的。
由于金属机壳上没有螺丝标注位。
给硬盘找最佳位置返工了两三回。
安装后金属机壳螺丝位置。
这时还要把塑料机壳的1个卡扣卸掉。
装上即可完工。
同方瘦客户机卖点指导手册同方(深圳)云计算技术股份有限公司2012-12目录一、瘦客户机和Mini PC概念浅谈 (3)1、瘦客户机概念 (3)2、Mini PC概念 (3)二、同方瘦客户机优势 (3)1、同方瘦客户机与PC及Mini PC比较 (3)2、同方瘦客户机与国内厂商瘦客户机比较 (5)一、瘦客户机和Mini PC概念浅谈1、瘦客户机概念瘦客户机是使用专业嵌入式处理器,小型本地闪存,精简版操作系统的基于工业标准设计的行业专用产品。
其追求的目标是设备具有总拥有成本低、安全性高、可靠性强、易于管理维护等优点。
2、Mini PC概念所谓Mini PC,其实就是体积小巧的PC。
与普通PC相比,Mini PC的最大特征就是电脑主机在体积上进行“缩水“,例如将光驱盒硬盘安装位都竖立起来,主机内部电源的安装位也出现了相应的改变等。
二、同方瘦客户机优势同方凭借其在瘦客户机市场的多年积累和挖掘,提炼出品质上佳的同方瘦客户机产品。
下面,将与PC,Mini PC和其他瘦客户机厂商的品质进行比较:1、同方瘦客户机与PC及Mini PC比较1)无风扇,静音PC内部安装有CPU风扇,电源风扇等,运行时,CPU风扇,电源风扇等声音明显,且后期使用时由于灰尘,润滑等问题,噪声日益提高;由于Mini PC体积较PC小,相应的内部空间也变得很狭小,空气在如此狭小的空间内不易流通,因此散热性能成为Mini PC的一个瓶颈;而为了加强散热,Mini PC的主机内部会采用多个散热风扇,而随着风扇的增多,电脑运行时的噪音问题也随之而来,运行时的噪音根本得不到很好的控制,降低了客户的环境舒适度;而同方瘦客户机采用硬件嵌入式方案,整机无风扇设计,设备运行时可以完美的控制噪声问题,保证静音,提高客户的环境舒适度;2)稳定性高PC和Mini PC采用高功耗CPU,CPU采用PGA封装方式,易松动,主板稳定性低;同方瘦客户机采用硬件一体化设计,高速低功耗CPU,CPU采用BGA封装方式,尺寸小,直接封装到主板上,主板稳定性高;3)接口设计丰富,且为主板支持PC和Mini PC内采用机械插拔式接口,随着使用时间的加长,易出现松脱等现象;连接线多,布线复杂;且主板直接支持外设接口少,后期扩展需要使用各类扩展卡,由于扩展卡为小器件,本身质量低,且供应厂商各异,外设兼容性降低,稳定性也随之降低;同方瘦客户机为满足外设需求丰富的环境使用,有加强设计。

2. 将USB 闪存驱动器连接到您要部署捕获映像的瘦客户机设备,然后打开该设备。
3. 按照屏幕中的说明执行操作。
当您拔下USB 闪存驱动器并重启系统电源后,映像将解包。
此过程需要3–5 分钟,具体取决于闪存驱动器速度和内部闪存大小。
