Problems solved by technology

Since the video information no longer passes through the BMC management chip, the KVM remote window management function cannot be realized. At this time, the server cannot obtain the remote server operation window in real time, which brings great difficulty to the remote management of the server.

Embodiment Construction

[0032] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. It should be understood that the following examples are only used to illustrate and explain the present invention, but not to limit the technical solution of the present invention.

[0033] The embodiment of the system that realizes remote management of keyboard, video and mouse provided by the present invention has a structure such as figure 1 As shown, it includes a sequentially connected data control unit and cache data switching unit, wherein:

[0034] The data control unit is used to decode and re-encode the received data and signals of the independent graphics card through PCIE (x16, called bus interface standard 16 channels) protocol to generate PCIE (x1, called The bus interface standard 1 channel) video data signal is transmitted to the cache data switching unit;

[0035] The cache data switching unit is u...

Abstract

The invention discloses a system and a method for realizing keyboard video mouse (KVM) remote management. The system includes the following steps: when monitoring that an external discrete graphics card is accessed, a data control unit decodes and recodes the received data and signals of the discrete graphics card through a bus interface standard 16 channel protocol to generate a bus interface standard 1 channel video data signal and transmits the bus interface standard 1 channel video data signal to a cache data switching unit; and the cache data switching unit receives and processes the bus interface standard 1 channel video data signal and transmits the bus interface standard 1 channel video data signal to a baseboard management controller (BMC) to manage a chip graphics card channel. The system can realize the KVM remote management function under two modes of coexistence of the external discrete graphics card and a BMC integrated graphics card, and the external discrete graphics card and the BMC integrated graphics card can be switched smoothly. In addition, automatic backup of operation recording data of a remote user is supported, so that the operation data of the user can be stored permanently.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a system and method for realizing remote management of a keyboard, video and mouse. Background technique [0002] In today's server product systems, the remote management technology of the keyboard video mouse (KVM, Keyboard Video Mouse) has been widely used through the coexistence mode of the integrated graphics card of the baseboard management controller (BMC, Baseboard Management Controller). Managed features, including: local and remote diagnostics, console support, configuration management, hardware management, and troubleshooting. [0003] Among them, the KVM management based on the graphics card integrated in the BMC is called KVM over IP, which means digitizing keyboard, video and mouse data, and moving KVM data from the client to the server through IP technology. KVM over IP connects directly to the KVM signal on any client computer and moves its digitized data wit...
