Description

System and method for controlling booting procedures of multiple computer devices using remote operation device

technical field

The invention relates to a remote operation device, in particular to a remote operation device capable of controlling multiple computer devices through a network.

Background technique

Since computers have been widely used in individuals and companies, the access to large amounts of data is becoming more and more frequent, and general companies generally use servers to process various data accesses. The common server structure is a rack mountable server, and multiple servers can be placed in a rack for easy management and placement. However, it is impossible for users to configure their own keyboards, monitors and servers for each server. mouse, as these peripherals take up considerable space. Generally speaking, most of the time, the server only accepts the requirements of the terminal computer through the network to perform corresponding data processing, so even if the server itself is not equipped with a keyboard, monitor and mouse, it can still operate normally. However, if each server is equipped with a keyboard, Monitors and mice will cause waste of resources and increase company costs, so general system managers use a switch (KVM switch) to manage multiple servers, wherein each server is connected through a keyboard cable, a video A video cable and a mouse cable are connected to the switcher, and a control console equipped with a keyboard, monitor and mouse can be connected to any server through the switcher to control and manage the server. In addition, in order to realize the function of remote control, the control terminal can also manage and control the remote computer device through the network.

Please refer to FIG. 1 , which is a schematic diagram of a known switch system (KVM). A plurality of servers 10 are connected to a switch 14 via a cable 12, and are connected to a network 16 via another cable 20, and the switch 14 is connected to the network 16 via a cable 15, and the switch 14 is equipped with a digital/analog converter (digital/analog converter, D/A converter) 21 is used for converting digital signal into analog signal and an analog/digital converter (analog/digital converter, A/D converter) 22 is used for converting analog signal into digital signal. In addition, there is a control computer 18 at the far end connected to the network 16 via a cable 19. Therefore, the control computer 18 can transmit signals to the remote switch 14 through the network 16. Similarly, the switch 14 can also pass through the network 16. The signal is transmitted to the remote control computer 18. Therefore, any server 10 can be selected to be connected to the control computer 18 through the switch 14 , and the control computer 18 can further remotely manage multiple servers 10 through the switch 14 . However, the switch 14 itself is limited by the hardware specifications, so the number of servers 10 connected to the switch 14 has an upper limit. When the server 10 exceeds the connection limit of the switch 14, multiple switches 14 must be used to completely control all the servers 10 , and each switch 14 must set a mapping table (mapping table) to manage which output port (port) corresponds to which server, so that the switch 14 can correctly switch to the server to be managed. In addition, each server 10 must be connected to the switcher 14 using cables 12 , which not only requires additional costs, but also makes it difficult to organize due to messy cables. It is known that the switch 14 must use a digital/analog converter 21 to convert the digital control signal transmitted by the control computer 18 into a corresponding analog control signal. Similarly, the analog output signal of the server 10 must pass through an analog/digital converter 22 After being converted into a digital signal, it can be transmitted to the control computer 18 through the network 16. In addition, the switcher 14 must judge the specifications of each output interface when outputting the signal, such as a PS/2 interface or a USB interface, and make corresponding adjustments for various interfaces. The corresponding signal is converted to output a compatible signal, which reduces the efficiency of remote control and increases the inconvenience of management due to the increased time for signal judgment and signal conversion.

In addition, the known switcher must perform appropriate analog/digital conversion on the output image signal of the computer device or the input control signal of the remote operating system through the digital/analog converter and the analog/digital converter, and make the input signal or output signal It can be applied around different interfaces to generate corresponding control signals and image outputs. However, the present invention does not need to go through the process of digital/analog conversion, because the output signals stored in the output buffer of the computer device are directly passed through The network is transmitted to the output buffer of the remote operation device, and the control signal of the input buffer of the remote operation device is directly transmitted to the input buffer of the computer device through the network, so the present invention can read the output buffer The temporary register and the output buffer register directly control various peripheral devices, so there is no need for corresponding data conversion for peripheral devices of various specifications, so the convenience and efficiency of management can be improved.
