[分享]什么是KVM切换器
<p><font face="Verdana">服务器监管关键设备--多电脑切换器(KVM Switch) <img src="http://p1.images22.51img1.com/6000/yetoten/1fb5753069e6fb55f54cd1c7243e6b5a.jpg"/></font></p><font face="Verdana"><p><br/> KVM多电脑切换器是一项先进的硬件解决方案，更是现代服务器监管的关键设备，可协助用户通过由单一键盘 (Keyboard) 、显示器 (Video) 及鼠标 (Mouse) 所组成的控制端，轻松访问并集中管理多达上千台电脑。KVM多电脑切换器适用对象涵盖SOHO族群、中小型企业乃至于大型跨国企业。KVM多电脑切换器对于企业机房或数据中心的空间及信息环境能创造广大的效益，不只能降低能源消耗、节省机架与机房空间，还能避免多余的键盘、显示器与鼠标所造成的杂乱。而且通过KVM多电脑切换器的集中管理，可协助企业信息人员大幅简化工作流程、强化企业生产力。随着全球化与网络普及化的趋势，具备远程控管功能的KVM over-IP解决方案更可充分满足企业对于跨国机房管理的需求。</p>

<p><font face="Verdana"><font face="Verdana">1.为什么要使用KVM切换器？ <img src="http://p8.images22.51img1.com/6000/yetoten/846e17de91f7d956e28a26aa8c294bfc.jpg"/></font></font></p>
<p><font face="Verdana"><font face="Verdana"><br/> KVM切换器的许多好处都非常显而易见，您可以重新利用空间及整齐地重整桌面上或机架上2、3或更多计算机的设备；您可以节省服务器机房及信息中心里面不常使用的键盘、屏幕及鼠标等设备成本；您也可以中央控制管理多台计算机，而不需麻烦的由一台使用者工作站换到另一台使用者工作站。 此外，还可以节省空调、能源等消耗; 节省机架、设备成本; 以及地面空间。<br/> 2.KVM切换器可满足我的应用吗？ KVM 切换器通常应用于一或多位管理员管理多台计算机的环境，或是一位使用者必须操作2或多台计算机的环境，包括网络操作中心、信息中心、服务器机房、软件开发、测试实验室、服务中心、部门局域网及桌面上同时安装多台计算机。符合您的操作方式的KVM切换器可以提供的生产力附加价值，远超过空间、硬件及家具的节省。 但是，除非您确定所选择的「解决方案」不会导致新的问题，否则请勿相信所有的保证，请查找与您的操作需求相符，并可轻松且经济地扩充、升级及重新配置的KVM切换器，选择不论您的硬件组合为何 都可以完美地进行工作的切换器。</font></font></p>
<p><font face="Verdana"></font> </p>
<p>KVM的使用节省了机房内机柜的使用空间，节省了企业的采购成本，也节省了能源的消耗。</p>
<p>使企业管理，维护服务器的步骤更加简洁，快速。</p>
