Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present disclosure shall have the usual meanings understood by those skilled in the art to which the present disclosure belongs.

A server display method, device, device, and storage medium according to embodiments of the present disclosure will be described below with reference to the accompanying drawings.

As shown in FIG. 1 , the motherboard of the server includes a BMC, a PCH (Platform Controller Hub, platform controller hub), a CPU (Central Processing Unit, central processing unit) and memory. Among them, the graphics card is integrated in the BMC, the graphics card is connected to the local monitor, and the video memory is shared with the memory. The remote terminal can remotely log in to the server through BMC's KVM technology, and request data such as pictures and videos from the server.

In the server display method provided by the embodiment of the present disclosure, when the remote terminal requests data such as pictures and videos to be displayed on the display from the server through the KVM technology, according to the preset graphics card mode, the local output operation of the graphics card is controlled through the BMC, so that the server only Data such as pictures and videos are transmitted to the remote terminal, but the local display does not display these pictures, videos and other data, so as to avoid server data leakage and improve data security.

The execution subject of the embodiments of the present disclosure may be a server or a BMC disposed on a mainboard of the server. The program for setting the graphics card mode is pre-set in the BMC. When the BMC runs the program for the first time in the server, the mode setting interface is displayed on the local monitor. The mode setting interface includes the mode options corresponding to the preset data mode and the non-display mode corresponding mode options. Obtain the mode option selected by the user from the mode setting interface displayed on the local monitor. Set the display mode of the graphics card to the display mode corresponding to the mode option selected by the user.

In the mode setting interface shown in Figure 2, it shows "During the remote KVM access process, the display mode of the local display: display preset data, not display", where "display preset data" is the corresponding display mode of preset data mode option, "do not display" is the mode option corresponding to the no-display mode. Users can choose the display mode they want to set in the mode setting interface.

When the mode option selected by the user is the mode option corresponding to the non-display mode, an interface of the graphics card is set as a shielded interface, and the shielded interface is used for local display control during remote KVM access. During remote KVM access, BMC controls the graphics card to shield local output through this shielding interface.

In some embodiments of the present disclosure, the above mode setting interface further includes an interface for uploading data. If the user chooses to display the mode option corresponding to the preset data mode, the user can also upload custom data from the interface for uploading data, and the data uploaded by the user can be text, pictures, or videos. When the BMC monitors the data uploaded by the user, it obtains the preset data submitted by the user from the mode setting interface, and stores the preset data in the video memory.

In other embodiments of the present disclosure, when the mode option selected by the user is to display the preset data mode, the user may not upload the preset data, but determine the manufacturer identification information of the BMC as the one corresponding to the display preset data mode. The preset data stores the manufacturer identification information in the video memory. Wherein, the vendor identification information may be a vendor name, a logo pattern, and the like of the BMC.

After setting the display mode of the graphics card through the above method, when the remote terminal requests the data to be displayed through the KVM technology, the following steps are taken to prevent the local display from leaking the server data. As shown in Figure 3, specifically include:

Step 101: Receive a KVM data request sent by a remote terminal, and acquire data to be displayed corresponding to the KVM data request.

After the remote terminal logs in to the server remotely through KVM technology, if the remote terminal needs to view pictures or videos in the server and wait for the data to be displayed, the remote terminal can send a KVM data request to the server.

Step 102: Send the data to be displayed to the remote terminal through the network port.

Send the acquired data to be displayed to the remote terminal through the network port.

Step 103: Control the local output operation of the graphics card according to the preset graphics card mode, where the graphics card mode includes a mode of displaying preset data or a mode of not displaying.

When the preset display mode of the graphics card is the display preset data mode, according to the preset display preset data mode, the preset data is obtained from the video memory, and the graphics card is controlled to transmit the preset data to the local monitor for display through the VGA interface. Therefore, when the remote terminal requests the data to be displayed through the KVM technology, the local display will not display the data to be displayed, which prevents the local display from leaking the server data and ensures the data security of the server.

When the preset graphics card mode is non-display mode, according to the preset non-display mode, control the graphics card to shield the output of the data to be displayed through the preset shielding interface, and not transmit the data to be displayed to the local display, thereby avoiding leakage of server data , to ensure data security on the server.

The embodiment of the present disclosure does not limit the execution order of the above-mentioned steps 102 and 103 . Steps 102 and 103 can be executed simultaneously, or step 102 can be executed first and then step 103 can be executed, or step 103 can be executed first and then step 102 can be executed.

In the embodiment of the present disclosure, when the remote terminal requests the data to be displayed in the server through the KVM technology, the BMC controls the graphics card to output only the preset data according to the preset graphics card mode, or controls the graphics card to turn off the local output. In this way, the graphics card is prevented from displaying the data to be displayed requested by the remote terminal through the local display, and the leakage of the data to be displayed by the local display is prevented, thereby improving the data security of the server.
