Description

Multi-node server, method, device and medium applied to multi-node server

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on January 30, 2024, with application number 202410129788.X and titled “Multi-node server, method, device and medium applied to multi-node server”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of powering on a shared board for a multi-node server, and in particular to a multi-node server, a powering method for a shared board for a multi-node server, a powering device for a shared board for a multi-node server, and a computer non-volatile readable storage medium. Background Art

[0004] Servers generally include Standby power and Core power. Standby power refers to the standby power supply, which is the power supply that ensures that the server remains on when it is not in operation. Standby power is usually smaller and is only used to maintain the operation of the server's hardware equipment and monitoring system. The power consumption of the standby power supply is lower, but energy conservation and environmental protection still need to be paid attention to. Core power refers to the core power supply, also known as the working power supply, which is the main power supply required for the normal operation of the server. It provides power to the server and drives key components such as the processor, memory, hard disk, and cooling system. The power consumption of the core power supply depends on the performance and configuration of the server and is usually higher.

[0005] After the PSU (Power Supply Unit) is plugged in and before the server is powered on, it enters standby mode, requiring only standby power. When the server power button is pressed or a remote power-on command is issued, the system power supply module begins generating core power to maintain normal system operation.

[0006] Servers typically use a CPLD (Complex Programmable Logic Device) or FPGA (Field Programmable Gate Array) to monitor the VR (Voltage Regulator Module) chip enable and Power Good signals to gradually power on the power supply in a predetermined sequence. The Power Good signal is a power management signal used to indicate that the power supply is stable and ready to power the server.

[0007] In a multi-node server, each node's power supply is independent. However, these nodes share some common boards, such as fan boards, riser cards (expansion cards), and network management boards, which need to be interconnected with each node. Because each node's power control system is independent, powering up each node cannot be synchronized, which can lead to leakage. Therefore, isolation circuits must be added to all signals interconnecting the nodes. However, excessive isolation circuits can affect board design layout and increase hardware costs.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without inventive effort are also within the scope of protection of this application.

[0065] Existing servers usually use CPLD (Complex Programmable Logic Device) or FPGA (Field Programmable Gate Array) to control nodes to power on in a predetermined order. The multi-node power-on control system is independent of each other, and leakage problems caused by asynchrony are avoided by adding isolation circuits to all signals interconnected with each node. However, adding isolation circuits to all multi-node interconnected signals can easily lead to excessive isolation circuits, thereby affecting the board design layout and increasing hardware costs. In order to optimize the multi-node power-on control system, all shared power supplies for multiple nodes can be powered on synchronously, thereby reducing hardware isolation circuits, optimizing system design layout, and reducing hardware costs.

[0071] A power-on synchronization device 104 is provided between the master node 101 and the slave node 102. The power-on synchronization device 104 includes an isolation module 1041, a master node signal interconnection module 1042, and a slave node signal interconnection module 1043. The power-on synchronization device 104 is connected to the master node 101 via the master node signal interconnection module 1042, and to the slave node 102 via the slave node signal interconnection module 1043. The master node signal interconnection module 1042 and the slave node signal interconnection module 1043 are connected via the isolation module 1041. The isolation module 1041 can be used to isolate the signals between the master node 101 and the slave node 102, thereby preventing power leakage from the master node 101 to the slave node 102, or vice versa.

[0072] In some feasible embodiments, the master node 101 may send a power-on request to the master node signal interconnection module 1042. After receiving the power-on request, the master node signal interconnection module 1042 may output the power-on request to the slave node signal interconnection module 1043 via the isolation module 1041.

At this time, the first power-on control module can respond to the power control instruction and output a power control instruction to the second power supply module. The second power supply module can respond to the power control instruction and control the power supply to the target shared board 103. For example, the second power supply module can respond to the power control instruction to power on or off the target shared board 103.

[0092] In some feasible embodiments, the first power-on control module can also be used to send the power status of the second power module to the first power-on management module, so that the first power-on management module can control the second power module based on the power status of the second power module.

[0106] After receiving the power-on preparation response, the master node signal interconnection module 1042 can send it to the first power-on management module. After receiving the power-on preparation response, the first power-on management module can clear the power-on completion flag n of the target shared board 103 and issue a power-on request to the second power-on management module via the power-on synchronization device 104. The power-on completion flag is cleared to ensure that the system or device can be properly initialized and enter normal operating state after power-on, and is used to indicate whether the system has completed the necessary initialization process. The power-on request can be used to request the second power-on management module to control the fourth power supply module to supply power to the target shared board 103.

[0107] The power-on request can first be sent to the master node signal interconnection module 1042 by the first power-on management module, and then sent to the slave node signal interconnection module 1043 by the master node signal interconnection module 1042 through the isolation module 1041; after receiving the power-on request, the slave node signal interconnection module 1043 can send it to the second power-on management module.

[0108] After receiving the power-on request, the second power-on management module can respond to the power-on request and supply power to the target shared board 103; at the same time, the second power-on management module can respond to the power-on request and send a power-on request response to the first power-on management module through the power-on synchronization device 104; the power-on request response can be used by the first power-on management module to determine that the second power-on management module has controlled the fourth power supply module to supply power to the target shared board 103.

[0109] The power-on request response can first be sent by the second power-on management module to the slave node signal interconnection module 1043, and then sent by the slave node signal interconnection module 1043 to the master node signal interconnection module 1042 via the isolation module 1041. After receiving the power-on request response, the master node signal interconnection module 1042 can control the second power supply module to supply power to the target shared board 103. At this point, the target shared board 103 is powered on.

[0115] In actual applications, the first power-on control module may send a first successful power supply signal to the first system management module when the second power supply module successfully supplies power to the target shared board 103; and the second power-on control module may also send a second successful power supply signal to the second system management module when the fourth power supply module successfully supplies power to the target shared board 103. The first successful power supply signal may indicate that the second power supply module successfully supplies power to the target shared board 103, and the second successful power supply signal may indicate that the fourth power supply module successfully supplies power to the target shared board 103.

[0116] After receiving the second successful power supply signal, the second system management module can transmit the second successful power supply signal to the first system management module through the power-on synchronization device 104; if the first system management module does not receive the first successful power supply signal and / or the second successful power supply signal, it can be determined that there is an abnormality in this power-on; at this time, the first system management module can issue a power-on abnormality alarm to inform the administrator that there is an abnormality in the power-on of the target shared board 103.

[0121] If n is determined to be equal to N, it can be determined that the synchronous power-on is completed; otherwise, it can be determined that some slave nodes 102 have not completed power-on; at this time, it is possible to wait for the remaining slave nodes 102 to complete powering.

[0134] Based on the above-mentioned multi-node server, an embodiment of the present application also provides a power-on method for a multi-node server for a shared board; specifically, please refer to Figure 4a, which shows a step flow chart of a power-on method for a shared board in a multi-node server of an embodiment of the present application; this method can be applied to the multi-node server mentioned in the above-mentioned embodiment, and the multi-node server may include a master node, a slave node, a power-on synchronization device, and at least one shared board shared between the master node and the slave node.

[0135] As shown in FIG4a , the method may include the following steps:

[0136] Step 401: The master node sends a power-on request for a target shared board to the slave node via a power-on synchronization device. In response to the power-on request, the slave node sends a power-on request response to the power-on request to the master node via the power-on synchronization device and supplies power to the target shared board.

[0137] In some feasible embodiments, the master node may send a power-on request to the master node signal interconnection module; after receiving the power-on request, the master node signal interconnection module may output it to the slave node signal interconnection module through the isolation module.

[0138] After receiving the power-on request, the slave node signal interconnection module can output it to the slave node; in response to the power-on request, the slave node can supply power to the target shared board; in addition, the slave node can send a power-on request response to the master node in response to the power-on request.

[0139] Step 402: After receiving the power-on request response, power is supplied to the target shared board.

[0140] After receiving the power-on request response, the master node can supply power to the target shared board.

[0141] For example, as shown in FIG4b:

[0142] (1) After the power supply unit is connected, the first power supply module automatically supplies power to the first power-on management module.

[0143] (2) The master-slave setting module sets the first system management module as the master and the second system management module as the slave.

[0144] (3) After the first power-on management module works normally, it sends a power-on ready signal to the slave node.

[0145] (4) After receiving the power-on ready signal, the slave node sends a power-on ready response to the master node.

[0146] (5) After the master node waits to receive the power-on preparation response, the first system management module clears the power-on completion flag n and sends a power-on request for the target shared board to the slave node.

[0147] (6) After receiving the power-on request for the target common board, the slave node sends a power-on request response to the master node and controls the fourth power supply module to supply power to the target common board.

[0148] (7) After the master node receives the power-on request response from the slave node, it controls the second power supply module to supply power to the target shared board and monitors whether a successful power supply signal for the master node and the slave node is received; if received, the successful power supply signal is 1; it is determined whether the successful power supply signals of the master node and the slave node are both 1; if the successful power supply signals of the master node and the slave node are not 1, a power-on abnormality alarm is issued and a log is recorded; on the contrary, if the successful power supply signals of the master node and the slave node are 1, then (8) is performed.

[0149] (8) The power-on completion flag bit n is incremented by 1, and the first system management module determines whether n is equal to N. If n is equal to N, the synchronous power-on is completed; otherwise, if n is not equal to N, the process proceeds to step (6).

[0150] In this embodiment of the present application, the master node sends a power-on request for a target shared board to a slave node via a power-on synchronization device. In response to the power-on request, the slave node sends a power-on request response to the power-on request via the power-on synchronization device to the master node and supplies power to the target shared board. After receiving the power-on request response, power is supplied to the target shared board. Compared to using an isolation circuit, this embodiment of the present application uses only a single power-on synchronization device to synchronize power to multiple shared boards, thereby optimizing system design layout and reducing hardware costs.
