IVR Server

詳細簡介

最常見的是，一個控制臺服務器提供了數 串口，然后再連接到其他設備的串行端口的服務器，如路由器或交換機。 該主機連接，如連接的串行設備可以通過連接來訪問一個服務器轉移到控制臺 調制解調器，或通過與網絡 的終端仿真器 的軟件，如 遠程登錄 或 使用SSH，保持存活的連接，允許遠程用戶登錄的各種游戲機。

專用控制臺服務器設備，可從制造商在很多配置數量，以期從1至48串行端口數。 這些控制臺服務器主要用于安全遠程訪問控制臺端口與一個網絡的Unix服務器，Linux服務器，Windows服務器和任何設備。 其目的是讓網絡運營中心（NOC）人員進行安全的遠程數據中心管理與帶外管理資訊科技在世界任何地方的資產。 產品銷售作為控制臺服務器通常有非常先進的安全功能，以確保只有符合資格的人員可以訪問不同的服務器，而任何通過LAN傳輸，或通過互聯網的數據是加密的。 營銷作為一個控制臺應用服務器產品是非常具體，因為它確實是指用戶要什么事 - 遠程控制，監(jiān)測，診斷和通過網絡或互聯網解決設備。

有些用戶創(chuàng)造了他們自己的控制臺服務器使用現成的現成 商品電腦 硬件，低于通常是精簡與多串口卡通常運行 的類Unix 操作系統，如 Linux操作系統。 這種“土生土長”控制臺服務器可以更便宜，特別是如果升級內置組件，從已退休，并允許更大的靈活性將管理員完全控制在手中的設備的軟件驅動。 這包括充分利用和配置標準和加密一個廣泛的安全協議，使我們能夠創(chuàng)建一個控制臺服務器更安全。 但是，這個方案可能有一個更高 的TCO大多數工業(yè)控制臺服務器具有的物理dimension的一，少的可靠性和較高的機架-，since space requirements rack單位 （1U的）大小，而全- 1桌上型電腦 的PCI cards需要至少本版，使本土的解決方案更昂貴的一個案件 在同一地點 的基礎設施。

另一種方法，一些在服務器控制臺使用 群集 設置是 零調制解調器 線和 daisy-chain 游戲機以其他未使用的串行端口功能節(jié)點與其他一些主要的。

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.
