High-density extendible KVM monitoring system

Abstract

The invention discloses a high-density extendible KVM monitoring system, which belongs to the computer monitoring technology. A structure of the system comprises a control panel and controlled computers, wherein the control panel controls a plurality of controlled computers; each controlled computer is connected with a computer interface module; the controlled computers are connected with the computer interface modules through mouse cables, key cables and video cables; the plurality of computer interface modules are connected in series through super five category network cables to form controlled computer links, and each controlled computer link is connected to the control panel; a user monitors and operates the controlled computers through the control panel; and the control panel adopts high-speed switching technology and can extend n controlled computer links. Compared with the prior art, the high-density extendible KVM monitoring system integrates the multichannel switching technology into the user control panel seamlessly, so that the extendibility and signal quality of the system can be ensured better in narrow space.

Description

technical field [0001] The invention relates to a computer monitoring technology, in particular to a high-density and expandable KVM monitoring system. Background technique [0002] With the rapid development of society, the expansion of enterprise scale and the increase of data processing tasks have led to the development of server clusters, and server cluster systems with hundreds of nodes are not uncommon. Room space and fleet management are also becoming more of an issue. KVM technology came into being. [0003] KVM is an acronym for Keyboard, Video, and Mouse. It allows administrators to abandon redundant keyboards, monitors, and mice, and can access and control many servers through a set of KVM. [0004] The existing KVM system can be divided into parallel connection mode and serial connection mode. Among them, the parallel KVM switching system is directly connected to each controlled computer, resulting in a very limited number of systems that can be connected in th...

Problems solved by technology

There are also problems with such expansion: one is wiring, and additionally configuring a multiplexer makes the wiring cumbersome, and the entire system structure becomes less compact; the other is signal quality, and the multiplexer is to some extent A signal relay, which is very unfavorable for serial KVM that emphasizes signal quality. Each relay will inevitably involve signal reflection and crosstalk. As an independent device, the relatively long external leads make signal matching impossible. very good
