Problems solved by technology

[0005] The disadvantage of the existing technology is: the price of the BMC chip is relatively expensive; the supporting program code of the BMC is controlled by a very small number of manufacturers, and it is necessary to pay expensive intellectual property fees for both development and sales of products
If the user adopts the development method of purchasing the source code, it is necessary to support the cost of purchasing the source code

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The present invention provides a kind of blade server KVM device, described device comprises KM system and VGA system, CPU1 receives the switching command of described device, simultaneously switches KM system and VGA system to the same computing blade, and described KM system controls keyboard and The mouse performs local and remote control, and the VGA system performs local and remote control of the VGA.

[0022] The KM system includes a computing blade KM subsystem, a mid-board KM subsystem and a management module KM subsystem.

[0023] A blade server has multiple computing blades, and the design of each computing blade is the same. figure 2 Only two computing blades are shown, that is, Blade1 (101) and BladeN (N-101), and other computing blades are omitted. N represents the Nth computing blade, and the N computing blades are all the same. In th...

Abstract

The invention provides a blade server KVW (keyboard, video and mouse) device. The device comprises a KM (keyboard and mouse) system and a VGA (video graphics array) system, wherein a CPU1 (central processing unit) receives a switching command of the device, and switches the KM system and the VGA system into the same computing blade at the same time; the KM system carries out local and remote control on a keyboard and a mouse, and the VGA system carries out local and remote control on the VGA. The device is low in cost, simple in structure, simple to achieve and low in cost, and the used chips are common ICs. Meanwhile, various KVM control modes are achieved. A user can automatically compile codes according to the understanding; no OSD (on-screen-display) menu mode exists in the existing BMC (baseboard management controller) management mode at present, and the problems such as intellectual property cost are also related.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a blade server KVM device. Background technique [0002] KVM, namely Keyboard, VGA, and Mouse, is the abbreviation of keyboard, video, and mouse, and is a conventional IO device of a computer. In general, each computer has its own KVM system. For the blade server, because it has a unique topology, its KVM design has its own unique features. [0003] OSD (On-Screen-Display) is an on-screen menu adjustment method. Generally, after pressing the Menu button, a rectangular menu of various adjustment item information of the display will pop up on the screen. Through this menu, various working indicators of the display, including color, mode, geometric shape, etc., can be adjusted to achieve the best use status. [0004] At present, the commonly used method of KVM is to place a baseboard management controller (BMC) chip (such as the AST2300 chip of Aspeed Company) on th...
