详细简介

最常见的是,一个控制台服务器提供了数 串口,然后再连接到其他设备的串行端口的服务器,如路由器或交换机。 该主机连接,如连接的串行设备可以通过连接来访问一个服务器转移到控制台 调制解调器,或通过与网络 的终端仿真器 的软件,如 远程登录 或 使用SSH,保持存活的连接,允许远程用户登录的各种游戏机。

专用控制台服务器设备,可从制造商在很多配置数量,以期从1至48串行端口数。 这些控制台服务器主要用于安全远程访问控制台端口与一个网络的Unix服务器,Linux服务器,Windows服务器和任何设备。 其目的是让网络运营中心(NOC)人员进行安全的远程数据中心管理与带外管理资讯科技在世界任何地方的资产。 产品销售作为控制台服务器通常有非常先进的安全功能,以确保只有符合资格的人员可以访问不同的服务器,而任何通过LAN传输,或通过互联网的数据是加密的。 营销作为一个控制台应用服务器产品是非常具体,因为它确实是指用户要什么事 - 远程控制,监测,诊断和通过网络或互联网解决设备。

有些用户创造了他们自己的控制台服务器使用现成的现成 商品电脑 硬件,低于通常是精简与多串口卡通常运行 的类Unix 操作系统,如 Linux操作系统。 这种“土生土长”控制台服务器可以更便宜,特别是如果升级内置组件,从已退休,并允许更大的灵活性将管理员完全控制在手中的设备的软件驱动。 这包括充分利用和配置标准和加密一个广泛的安全协议,使我们能够创建一个控制台服务器更安全。 但是,这个方案可能有一个更高 的TCO大多数工业控制台服务器具有的物理dimension的一,少的可靠性和较高的机架-,since space requirements rack单位 (1U的)大小,而全- 1桌上型电脑 的PCI cards需要至少本版,使本土的解决方案更昂贵的一个案件 在同一地点 的基础设施。

另一种方法,一些在服务器控制台使用 群集 设置是 零调制解调器 线和 daisy-chain 游戏机以其他未使用的串行端口功能节点与其他一些主要的。

以下是英文版:

A console server (console access server, console management server, serial concentrator, or serial console server) is a device or service that provides access to the system console of a computing device via networking technologies.

Most commonly, a console server provides a number of serial ports, which are then connected to the serial ports of other equipment, such as servers, routers or switches. The consoles of the connected devices can then be accessed by connecting to the console server over a serial link such as a modem, or over a network with terminal emulator software such as telnet or ssh, maintaining survivable connectivity that allows remote users to log in the various consoles without being physically nearby.

Dedicated console server appliances are available from a number of manufacturers in many configurations, with the number of serial ports ranging from one to 48. These Console Servers are primarily used for secure remote access to Unix Servers, Linux Servers, Windows Servers and any device on the network with a console port. The purpose is to allow network operations center (NOC) personnel to perform secure remote data center management and out-of-band management of IT assets from anywhere in the world. Products marketed as Console Servers usually have highly advanced security functionality to ensure that only qualified personnel can access various servers and that any data that is transmitted across the LAN, or over the Internet, is encrypted. Marketing a product as a console server is very application specific because it really refers to what the user wants to do - remotely control, monitor, diagnose and troubleshoot equipment over a network or the Internet.

Some users have created their own console servers using off-the-shelf commodity computer hardware, usually with multiport serial cards typically running a slimmed-down Unix-like operating system such as Linux. Such "home-grown" console servers can be less expensive, especially if built from components that have been retired in upgrades, and allow greater flexibility by putting full control of the software driving the device in the hands of the administrator. This includes full access to and configurability of a wide array of security protocols and encryption standards, making it possible to create a console server that is more secure. However, this solution may have a higher TCO, less reliability and higher rack-space requirements, since most industrial console servers have the physical dimension of one rack unit (1U), whereas a desktop computer with full-size PCI cards requires at least 3Us, making the home-grown solution more costly in the case of a co-located infrastructure.

An alternative approach to a console server used in some cluster setups is to null-modem wire and daisy-chain consoles to otherwise unused serial ports on nodes with some other primary function.
