Abstract

The invention provides a blade server KVM switching and cascade solution, relates to the technical fields of application and management of servers, VGA signal processing, single chip microcomputers and the like. According to the blade server KVM switching and cascade solution, an RJ45 on a main server management board and an RJ45 on a slave server management board connected through a cable, cascade management among blade servers is achieved, and VGA signals of equipment are transmitted to the main server management board through the cable and then are displayed on display equipment externally connected with the main server management board. The situation that input equipment of a main server end operates slave servers is achieved by keyboard mouse signals through the cable.

Description

[0001] technical field

[0002] This program involves the fields of server application and management, VGA signal processing and single-chip microcomputer technology, and is specifically a blade server KVM (Keyboard, Video, Mouse) switching and cascading solution. Background technique

[0003] With the increase in the amount of information and the rapid development and application of network technology, servers have become indispensable equipment in various industries. In practical applications, it is usually necessary to assign corresponding management and maintenance personnel to each server. The traditional management method is that each server is equipped with independent input and output devices, and each server is managed independently. Although this management method seems flexible, the workload of managers is relatively large, and the efficiency of daily management and maintenance is not high. In some applications, the KVMs of two servers that are relatively clos...

Examples

Embodiment Construction

[0023] Referring to the accompanying drawings, the content of the present invention will be described with specific examples for its implementation and working process.

[0024] Such as figure 1 As shown, F340 on the management board of the master server receives the keyboard or mouse data collected by CH375, packs the data and sends it to the slave server through UART0; F340 on the management board of the slave server receives the data sent by the master device through UART1. Data and judge whether the data is sent to this level of equipment, if so, send it to the server computing blade through the USB on the F340, if not, forward the data packet through UART0, and complete the transmission of keyboard or mouse data during cascading.

[0025] as attached figure 2 And attached image 3 As shown, the RGB signal on the slave server is divided into two channels by MAX4381, one channel R, G, B_OUT is the local video signal output for use by the local display device; one channe...
