Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
KVM (Keyboard Video Mouse) represents a Keyboard (Keyboard), a display (Video) and a Mouse (Mouse), i.e., a group of Keyboard, display and Mouse is used to control a plurality of devices, and plays an important role in remote scheduling and monitoring. Centralized management of the system and the network can be realized through the KVM; the manageability of the system is improved, and the working efficiency of a system administrator is improved; the area of a machine room is saved, and the total cost of ownership of network engineering and a server system is reduced; radiation generated by using a plurality of displays is avoided, and a healthy and environment-friendly machine room is built. With the KVM multi-host switching system, a system administrator can switch and manage between the hosts or servers of multiple different operating systems through a set of keyboard, mouse, and display. However, in the process of managing the remote terminal by applying the KVM, the local server is easily out of synchronization with the cursor information on the remote terminal, for example, the data sequence between the local server and the remote terminal is A, B, C, D, the cursor of the local server is moved from data a to data D, and when the data is synchronized by the conventional method, the cursor on the remote terminal is moved from data a to data B, which brings errors to the local server to operate the remote terminal. The server provided by the application can improve the accuracy of the local server in operating the remote terminal.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a server according to an embodiment of the present disclosure.
The server provided by the embodiment of the application can include:
the host operating system 101 is used for generating operation information for operating the remote terminal and splitting the operation information into cursor operation information and non-cursor operation information;
a VGA (Video Graphics Adapter) 102 connected to the host operating system 101, for acquiring cursor operation information and transmitting the cursor operation information to the KVM 103;
a KVM103 connected to the VGA102, configured to receive cursor operation information transmitted by the VGA102 and transmit the cursor operation information to a MAC104(Measurement and Control) in a BMC (Baseboard Management Controller);
and the MAC104 connected with the KVM103 is used for transmitting cursor operation information to the remote terminal.
In the application, the operation information is divided into the cursor operation information and the non-cursor operation information by the host operating system, so that the effect of separating the cursor operation information and the non-cursor operation information in the operation information is realized, therefore, the cursor operation information or the non-cursor operation information can be independently processed according to the requirement subsequently, the coupling between the cursor operation information and the non-cursor operation information is solved, thus, when the server transmits the cursor operation information by means of VGA, KVM and MAC, the transmission of the non-cursor operation information together can be avoided, because the data volume of the non-cursor operation information is large, it takes a long time to transmit the non-cursor operation information, and therefore if the cursor operation information is transmitted alone, the cursor operation information can be quickly transmitted to the remote terminal by the server, and the cursor operation information can be quickly synchronized between the server and the remote terminal.
It should be noted that the KVM may directly transmit the cursor operation information to the MAC, or the KVM may indirectly transmit the cursor operation information to the MAC by other means, etc.; and the trigger condition for transmitting the cursor operation information from the KVM to the MAC can be flexibly determined according to actual needs, for example, the KVM can transmit the cursor operation information to the MAC after the operation capture interrupt is generated, and the like.
The server comprises a host operating system and a server, wherein the host operating system is used for generating operation information for operating the remote terminal and splitting the operation information into cursor operation information and non-cursor operation information; the VGA is connected with the host operating system and used for acquiring cursor operation information and transmitting the cursor operation information to the KVM; the KVM connected with the VGA is used for receiving the cursor operation information transmitted by the VGA and transmitting the cursor operation information to the MAC in the BMC; and the MAC is connected with the KVM and is used for transmitting the cursor operation information to the remote terminal. In the application, the host operating system of the server splits the operating information into cursor operating information and non-cursor operating information, and transmits the cursor operating information to the remote terminal through VGA, KVM and MAC, so that the remote terminal can quickly acquire the cursor operating information, the cursor synchronization rate between the remote terminal and the server is improved, and the accuracy of operating the remote terminal by the local server is improved.
In the server provided in the embodiment of the application, in order to facilitate synchronization of non-cursor operation information between the server and the remote terminal, the non-cursor operation information may also be transmitted to the remote terminal through the VGA, the KVM, and the MAC, that is, the VGA is further configured to acquire the non-cursor operation information and transmit the non-cursor operation information to the KVM; the KVM is also used for receiving the non-cursor operation information transmitted by the VGA and transmitting the non-cursor operation information to the MAC; the MAC is also used to transmit non-cursor operation information to the remote terminal.
In the server provided in the embodiment of the present application, since the VGA needs to transmit the cursor operation information and the non-cursor operation information to the KVM, when the VGA transmits the cursor operation information or the non-cursor operation information through one transmission channel, there is a transmission conflict, which may affect the transmission rate of the cursor operation information, and in order to avoid that a single transmission channel affects the transmission rate of the cursor operation information, please refer to fig. 1, in the process of connecting the VGA to the KVM, the VGA may be connected to the KVM through the first transmission channel and the second transmission channel; correspondingly, in the process that the VGA acquires the cursor operation information and transmits the cursor operation information to the KVM, the VGA can acquire the cursor operation information and transmit the cursor operation information to the KVM through the first transmission channel; in the process that the VGA acquires the non-cursor operation information and transmits the non-cursor operation information to the KVM, the VGA can acquire the non-cursor operation information and transmit the non-cursor operation information to the KVM through the second transmission channel.
It should be noted that the types of the first transmission channel and the second transmission channel may be determined according to actual needs, for example, the second transmission channel may be a transmission channel with a DVI (Digital Visual Interface) port, and the like, and the application is not limited in this respect. In addition, in fig. 1, DVI _2 is also the second transmission channel, and curser INF is also the first transmission channel.
In the server provided by the embodiment of the application, in order to simplify the structure of the server, both the VGA and the KVM can be internally arranged in the BMC.
In a server provided in an embodiment of the present application, the server may further include:
a video memory DDR (double Rate memory) 105 connected to the host operating system 101, the VGA102, and the MAC104, respectively, for caching the received operation information and/or cursor operation information and/or non-cursor operation information;
and the display 106 is connected with the VGA102 and used for receiving and displaying the operation information transmitted by the VGA 102.
In practical application, when the server locally displays the operation information, the host operating system can directly transmit the operation information to the VGA, and the VGA can directly transmit the operation information transmitted by the host operating system to the display for displaying; in the application process of the server, the situation that the VGA cannot process the operation information quickly due to excessive data or excessive data of the operation information may occur, at this time, the VGA needs to store corresponding operation information and/or cursor operation information and/or non-cursor operation information by means of the video memory DDR, and then process the information cached in the video memory DDR as needed, for example, the VGA may read the operation information cached in the video memory DDR and transmit the operation information to the display for display, and the VGA may also read the cursor operation information cached in the video memory DDR and transmit the cursor operation information to the KVM or the like; in addition, in the process of transmitting the cursor operation information and/or the non-cursor operation information with the MAC, the KVM may also transmit a corresponding information acquisition instruction to the MAC, and the MAC then directly acquires the cursor operation information and/or the non-cursor operation information from the video memory DDR according to the information acquisition instruction.
It should be noted that, in the process of transmitting the operation information by the VGA, the operation information may also need to be processed according to function operation transmitted from the outside, for example, the image page in the current video memory is rotated, captured, and the like according to the host operating system, and at this time, the VGA needs to process the operation information according to the function operation first and then transmit the processed operation information; in the process, the VGA also needs the operation information after synchronous processing in the video memory DDR. In addition, in this application, a mode of providing data for the KVM by adding a transmission channel to the VGA instead of the video memory DDR can effectively avoid the limitation on the high resolution due to the DDR bandwidth, for example, if the video memory DDR is used to provide data for the KVM, there are three channels to access the video memory DDR: the host operating system writes, VGA reads, KVM reads, if the host has function operation to the picture, then need to increase two channels: for VGA reading and VGA writing, taking a frame rate of 1920 × 1200 resolution 60 frames with 32 bits as an example, if the above five channels simultaneously work at the peak value, the total DDR bandwidth needs to be close to 3GB/S, which needs very high DDR frequency and interface width, and if KVM reading DDR is reduced, the bandwidth requirement is reduced by at least one fifth, which is beneficial to reducing hardware cost or improving the maximum supportable resolution. In fig. 1, DDR _ INF1 is a transmission channel between the video memory DDR and the host operating system, DDR _ INF2 is a transmission channel between the video memory DDR and the VGA, and DDR _ INF3 is a transmission channel between the video memory DDR and the MAC; DVI _1 is also the transmission channel between VGA and display.
In the server provided in the embodiment of the present application, in order to facilitate the BMC to control the KVM and control the transmission of cursor operation information, during the connection process between the KVM and the MAC, the KVM may be connected to the MAC through the BMC operating system 107; correspondingly, in the process that the KVM transmits the cursor operation information to the MAC, the KVM may transmit the cursor operation information acquisition instruction to the BMC operating system, so that the BMC operating system controls the MAC to acquire the cursor operation information.
In practical applications, the server provided by the present application may further include: the BMC DDR108, which is connected to the KVM and the MAC, respectively, is used for caching cursor operation information and/or non-cursor operation information.
In a specific application scenario, in the case that the data size of the cursor operation information and/or the non-cursor operation information that the KVM needs to send is too large, the KVM may not be able to quickly transmit the cursor operation information and/or the non-cursor operation information to the MAC, at this time, the BMC DDR needs to be set in the BMC to cache the cursor operation information and/or the non-cursor operation information, and correspondingly, the KVM may send a corresponding acquisition instruction to the MAC during the process of transmitting the cursor operation information and/or the non-cursor operation information to the MAC, so that the MAC acquires the corresponding cursor operation information and/or the non-cursor operation information from the BMC DDR, and the like.
