The switching unit 363 further includes control pins A, B coupled to the switch 355, and can be commanded according to the request 13

34903twf.doc/I 201216079 The node used for the request and the usage status of the device management function of the baseboard management controller 362 (more specifically, using the dip switch 367 or the baseboard management controller 362 to select the node to be used for the request), the transmission control Signals to the control pins A, B of the switch 355 to control the switch 355 to switch the port used. The signal output from the pin A of the substrate management controller 362 is used to select the signal output from the pin B of the substrate management controller 362 or the signal output from the pin A of the dip switch 367. For example, when the signal outputted by the pin A of the substrate management controller 362 is 〇, the signal outputted by the pin A of the dip switch 367 is selected; if it is 1, the output of the pin B of the substrate management controller 362 is selected. Signal. The signal outputted by the pin B represents the code of the node selected by the substrate management controller 362. For example, the signals of the 〇 and 1 are output through the three pins to represent the nodes 1 to 8, respectively, but the number of the pins can be The number of nodes to which the system is connected is not limited to this. The pin C represents whether the device management function of the baseboard management controller 362 has been allocated to a certain node. For example, when the signal output by the pin C is 〇, the device management function representing the baseboard management controller 362 has been configured, so There is no need to isolate the connection between the switch 355 and the substrate management controller 362. If it is 1, the device management function representing the substrate management controller 362 is not configured, so the isolation switch 355 and the substrate management controller 362 are required. Link. Further, the function of the pin B of the dial switch 367 is to select the pin A of the dip switch 367 to be used to select a node, or to select a base.

201216079 iuu42〇.fW 34903twf.doc/I Node selected by board management controller 362. For example, when the signal of the pin B of the dip switch 367 is 0, it means that the pin A of the dip switch 367 is forcibly selected to select the node; if it is 1, the substrate management controller 362 determines the selected node, and the substrate The selection manner of the management controller 362 is as described above, and details are not described herein again. When the pin C of the substrate management controller 362 outputs a signal of 0, it means that the device management function of the substrate management controller 362 has been configured, and when the pin B of the dip switch 367 also outputs the signal of the chirp, the gate 365 is The signal of 〇 is output to the control pin B of the switch 355 to release the isolation between the switch 355 and the substrate management controller 362. At this time, the multiplexer 366 selects the signal of the pin B of the multiplexer 366 to the control pin A of the switch 355 according to the signal output from the pin A of the dip switch 367 to control the switch 355. The connection port and wiring used are switched to the port corresponding to the pin B output signal of the multiplexer 366.

The controller 362 issues a control command to maintain and control the node from the remote virtual device through the device management function of the baseboard management controller 362. Further, in another embodiment, the substrate management controller 362 performs a booting process of a basic input/output system (BIOS), for example, after starting the node via the above-described step S512, and executes the job as needed. The installation and update actions of the system are described in detail below with reference to an embodiment. 3 is a flowchart of a method for sharing a substrate management controller according to a third embodiment of the present invention. Referring to FIG. 6, the method of the present embodiment is continued after step S512 shown in FIG.

When the operating system of the node After the power is turned on, the user is referred to as a local device (4) device, or a control command is issued to the substrate 1 362 by the domain terminal to transmit the device management controller 362. The node is maintained and controlled. The controller 362 receives the user's operation on the peripheral device, and accordingly, performs a corresponding operation (step S6G8). After the user node=point operation, the node can be connected to the node by the baseboard management controller 362. The next node closes the node (step S61〇), and if the node is closed, the management function is provided for use by other nodes (step, fp window ta 'user can use the baseboard management controller 362 to node the node Restart, but the node is executed under the management function of the substrateless tube.

In summary, the server system and method of the shared substrate management controller of the present invention achieves keyboard, video, mouse (KVM), and storage control by sharing a single substrate management controller. Function, and can use local and remote keyboard, video, mouse, storage and other peripheral devices, and can perform the functions of the remote installation operating system. In this way, the VGA port, serial port and baseboard management controllers on all nodes can be removed, so that only one baseboard management controller needs to be configured for the entire server system. In this way, not only can the space problem be solved, but also the production cost of the server system can be greatly reduced. The present invention has been disclosed in the above embodiments, but it is not intended to limit the invention to those skilled in the art, and it is possible to make some modifications and refinements without departing from the spirit and scope of the invention.
