Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a server collaborative power-on / off device, method, system, and medium. Background Technology

[0002] With the development of cloud computing and big data technologies, data centers are facing an increasing volume of data. To increase the resource utilization of general-purpose servers and facilitate resource expansion, pooled server products have emerged, such as storage resource pooled servers and compute resource pooled servers. General-purpose servers can be flexibly paired with pooled servers via cables to achieve resource expansion. For server products with the above architecture, because pooled servers cannot work independently and can be regarded as components of the main server in the overall system, the timing control of the coordinated power-on and power-off of the entire system becomes particularly important.

[0003] Currently, the coordinated power-on / off between the main server and the pooled servers is achieved through the Baseboard Management Controller (BMC). However, as a crucial management unit of the server system, the BMC's main functions include server hardware monitoring and fault alarms, thermal speed control, power management, and firmware upgrades. Numerous maintenance operations are performed on the BMC, such as firmware upgrades. Since the BMC cannot coordinate power-on / off during these maintenance processes, the reliability and stability of the current coordinated power-on / off solution need improvement.

[0004] Therefore, those skilled in the art urgently need a server collaborative power-on / off device to solve the problem of insufficient reliability and stability of the current system power-on / off mechanism implemented through BMC between servers. Summary of the Invention

[0005] The purpose of this application is to provide a server collaborative power-on / off device, method, system, and medium to solve the problem of insufficient reliability and stability of current server-to-server power-on / off systems achieved through BMC.

[0006] To address the aforementioned technical problems, this application provides a server collaborative power-on / off device, comprising: a main server CPLD located at the main server and a pooled server CPLD located at the pooled server;

[0007] Communication connection between the master server CPLD and the pooled server CPLD;

[0008] The PWRGD terminals of the power management chips of the other components of the main server are connected to the CPLD of the main server, and the PWRGD terminals of the power management chips of the other components of the pooled server are connected to the CPLD of the pooled server.

[0009] Preferably, the communication connection between the master server CPLD and the pooling server CPLD includes:

[0010] The master server CPLD and the pooled server CPLD are connected via three independent GPIO communication channels, which are used to transmit power-on / power-off signals, master server power-on status, and pooled server power-on status, respectively.

[0011] To address the aforementioned technical problems, this application also provides a server collaborative power-on / off method, wherein a main server CPLD located at the main server and a pooled server CPLD located at the pooled server are communicatively connected, and the PWRGD terminals of the power management chips of the remaining components of the main server are connected to the main server CPLD, and the PWRGD terminals of the power management chips of the remaining components of the pooled server are connected to the pooled server CPLD; applied to the main server CPLD side, including:

[0012] When a power-on signal is detected, the power-on signal is sent to the pooled server CPLD so that the pooled server CPLD can perform the power-on operation;

[0013] The pooling server power-on status is detected by the pooling server CPLD. If it is in the power-on state, the power-on operation is performed. Specifically, when the pooling server CPLD detects that the power management chip PWRGD of the pooling server and other components of the pooling server are all in the power-on state, the power-on status of the pooling server is set to the power-on state.

[0014] When a shutdown signal is detected, a shutdown operation is performed;

[0015] The power management chip PWRGD of the main server and other components of the main server is detected. If they are all in the power-off state, a shutdown signal is sent to the pooled server CPLD, and the power-on state of the main server is set to the power-off state so that the pooled server CPLD can perform a shutdown operation.

[0016] Preferred options also include:

[0017] After sending the power-on signal to the pooling server CPLD, if it is detected that the power-on status of the pooling server returned by the pooling server CPLD is not in the powered-on state, the abnormal power-on status of the pooling server is latched into the register.

[0018] After the shutdown operation is performed, if the power-on state of the power management chip PWRGD terminal of the main server and other components of the main server is not detected to be the power-off state, the abnormal shutdown state of the main server is latched into the register.

[0019] Preferably, the power-on or power-off signal is transmitted between the main server CPLD and the pooled server CPLD using a transparent transmission method.

[0020] To address the aforementioned technical problems, this application also provides a server collaborative power-on / off method, wherein a main server CPLD located at the main server and a pooled server CPLD located at the pooled server are communicatively connected, and the PWRGD terminals of the power management chips of the remaining components of the main server are connected to the main server CPLD, and the PWRGD terminals of the power management chips of the remaining components of the pooled server are connected to the pooled server CPLD; applied to the pooled server CPLD side, including:

[0021] Upon receiving a power-on signal from the master server CPLD, perform a power-on operation;

[0022] The power-on status of the pooled server and the power management chip PWRGD of the other components of the pooled server is detected. If they are all in the powered-on state, the power-on status of the pooled server is set to the powered-on state so that the main server CPLD can perform the power-on operation.

[0023] When a shutdown signal sent by the master server CPLD is detected, check the power-on status of the master server returned by the master server CPLD;

[0024] If the power is off, a shutdown operation is performed; specifically, when the main server CPLD detects that the power management chip PWRGD terminals of the main server and all other components of the main server are in a power-off state, the main server power-on state is set to the power-off state.

[0025] To address the aforementioned technical problems, this application also provides a server collaborative power-on / off device, wherein a main server CPLD located at the main server and a pooled server CPLD located at the pooled server are communicatively connected, and the PWRGD terminals of the power management chips of the remaining components of the main server are connected to the main server CPLD, and the PWRGD terminals of the power management chips of the remaining components of the pooled server are connected to the pooled server CPLD; comprising:

[0026] The power-on signal sending module is used to send a power-on signal to the pooled server CPLD when a power-on signal is detected, so that the pooled server CPLD can perform a power-on operation;

[0027] The main server power-on module is used to detect the power-on status of the pooled server returned by the pooled server CPLD. If it is in the power-on state, the power-on operation is performed. Specifically, when the pooled server CPLD detects that the power management chip PWRGD of the pooled server and other components of the pooled server are all in the power-on state, the power-on status of the pooled server is set to the power-on state.

[0028] The main server shutdown module is used to perform a shutdown operation when a shutdown signal is detected.

[0029] The power-off signal sending module is used to detect the power-on status of the power management chip PWRGD of the main server and other components of the main server. If they are all in the power-off state, the power-off signal is sent to the pooled server CPLD, and the power-on status of the main server is set to the power-off state so that the pooled server CPLD can perform the power-off operation.

[0030] Preferred options also include:

[0031] The abnormal state latching module is used to latch the abnormal power-on state of the pooled server to a register if the power-on state of the pooled server returned by the CPLD is not "powered on" after the power-on signal is sent to the pooled server CPLD; and to latch the abnormal power-off state of the main server to a register if the power-on state of the power management chip PWRGD of the main server and other components of the main server is not "power-off" after the power-off operation is performed.

[0032] To address the aforementioned technical problems, this application also provides a server collaborative power-on / off device, wherein a main server CPLD located at the main server and a pooled server CPLD located at the pooled server are communicatively connected, and the PWRGD terminals of the power management chips of the remaining components of the main server are connected to the main server CPLD, and the PWRGD terminals of the power management chips of the remaining components of the pooled server are connected to the pooled server CPLD; comprising:

[0033] The pooled server power-on module is used to perform a power-on operation when it receives a power-on signal sent by the master server CPLD.

[0034] The power-on status setting module is used to detect the power-on status of the pooled server and the power management chip PWRGD of the other components of the pooled server. If they are all in the power-on state, the power-on status of the pooled server is set to the power-on state so that the main server CPLD can perform the power-on operation.

[0035] The power-on status detection module is used to detect the power-on status of the main server returned by the main server CPLD when a power-off signal sent by the main server CPLD is detected.

[0036] The pooled server shutdown module is used to perform a shutdown operation if the server is in a powered-off state. Specifically, when the main server CPLD detects that the power management chip PWRGD terminals of the main server and other components of the main server are all in a powered-off state, the main server's power-on state is set to the powered-off state.

[0037] To address the aforementioned technical problems, this application also provides a server collaborative power-on / off system, comprising:

[0038] Memory, used to store computer programs;

[0039] A processor is used to implement the steps of the server-coordinated power-on / off method described above when executing computer programs.

[0040] To address the aforementioned technical problems, this application also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the server collaborative power-on / off method described above.

[0041] This application provides a server collaborative power-on / off device. By establishing a communication connection between a main server CPLD (Power Management Controller) responsible for powering on the main server and a pooled server CPLD responsible for powering on the pooled servers, signal exchange between the main server CPLD and the pooled server CPLD can be achieved without a BMC (Power Management Controller) as an intermediary. Furthermore, the PWRGD terminals of the power management chips of the remaining components of the main server are connected to the main server CPLD and monitored by it. Therefore, the main server CPLD can detect the power-on status of the main server without using a BMC. Similarly, the pooled server CPLD can detect the power-on status of the pooled server by monitoring the PWRGD terminals of the power management chips of the remaining components of the pooled server, also without BMC involvement. Therefore, through the established communication connection, the main server CPLD and the pooled server CPLD can transmit power-on and power-off signals as well as the power-on status of the main and pooled servers, enabling system power-on / off between servers without BMC involvement. This effectively solves the problem of server collaborative power-on / off being impossible when the BMC is under maintenance or upgrade, improving reliability and stability. In addition, since the power-on and power-off signals and the power-on status of the server are all implemented by simple level signals, this collaborative power-on and power-off control based on CPLD and hardware signals has higher reliability and stability than the pure software implementation of BMC, further ensuring the normal operation of collaborative power-on and power-off between servers.

[0042] The server collaborative power-on / off method, apparatus, system, and computer-readable storage medium provided in this application correspond to the aforementioned apparatus and have the same effect. Attached Figure Description

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0053] The core of this application is to provide a server collaborative power-on / off device, method, system, and medium.

[0054] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] In current server applications, due to the limited resources of the main server, resource expansion is achieved through devices such as pooled servers. However, because pooled servers cannot operate independently, they can be considered components of the main server within the overall system. Taking a GPU pooled server as an example, when the entire system powers on, the GPU pooled server must be powered on first, followed by the main server; otherwise, the main server will not be able to recognize PCIe devices. Conversely, when the system powers off, the main server must be powered off first, followed by the GPU pooled server; otherwise, system crashes may occur.

[0056] PCIE: Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard.

[0057] I2C bus: A simple, bidirectional, two-wire synchronous serial bus. It requires only two wires to transmit information between devices connected to the bus.

[0058] Currently, during coordinated power-on, the master server BMC sends a power-on command to the pooled server BMC via the I2C bus and continuously polls the power-on status of the pooled servers. Only after ensuring the pooled servers are powered on does the master server perform the power-on operation. During coordinated power-off, the master server first performs a power-off action. After detecting the master server's power-off, the BMC sends a power-off command to the pooled server BMC via I2C, and the pooled server performs the power-off operation.

[0059] Specifically, the power-on and power-off operations of the servers are implemented by Complex Programmable Logic Devices (CPLDs) located on each server. The CPLD responsible for powering on and off the main server is called the main server CPLD, and the CPLD responsible for powering on and off the pooled servers is called the pooled server CPLD. There is no connection between the main server CPLD and the pooled server CPLD; the coordinated power-on and power-off of the servers is achieved through unified coordination by the BMC (Block Controller).

[0060] However, the aforementioned software-based collaborative power-on / off scheme can cause abnormal power-on / off of the entire machine due to BMC malfunctions or communication failures between the two management units, thereby affecting the normal operation of the server.

[0061] To address the aforementioned problems, this application provides a server collaborative power-on / off device, such as... Figure 1 As shown, it includes: a main server CPLD12 located at the main server 11 and a pooling server CPLD14 located at the pooling server 13;

[0062] Communication connection between the master server CPLD12 and the pooling server CPLD14;

[0063] The PWRGD terminals of the power management chips 15 (power management chip AE) of the other components of the main server 11 are connected to the main server CPLD 12, and the PWRGD terminals of the power management chips 15 (power management chip AE) of the other components of the pooled server 13 are connected to the pooled server CPLD 14.

[0064] PWRGD pin: Also known as the PWRGD terminal, it outputs a high or low level signal to indicate whether the corresponding device is powered on.

[0065] The PWRGD pins of the power management chips 15 of the remaining components of each server are connected to the corresponding CPLDs and monitored by the CPLDs. This allows the CPLDs to obtain the power-on status of the servers without the need for a BMC (strictly speaking, in the current architecture, the CPLD does not need to obtain the power-on status of the servers; the BMC only needs to send corresponding instructions after obtaining the power-on status, and the CPLD can then perform power-on and power-off operations according to the instructions sent by the BMC). Generally speaking, taking the main server 11 as an example, the main server 11 is considered to be powered on only when the main server 11 and all its other components are in a powered-on state.

[0066] Additionally, it should be noted that this embodiment does not limit the communication connection method between the main server CPLD12 and the pooling server CPLD14. It can be a wired connection or a wireless connection, and the communication protocol used is not limited, nor is the type of communication interface limited. The purpose is to establish a communication connection between the main server CPLD12 and the pooling server CPLD14, so that the two can transmit power-on signals and power-off signals, as well as monitor the power-on status of the main server 11 and the pooling server 13 without the aid of BMC.

[0067] However, this embodiment provides a preferred implementation: the main server CPLD12 and the pooling server CPLD14 establish a communication connection through a general-purpose input / output (GPIO) port.

[0068] Correspondingly, the power-on signal, power-off signal, and power-on status of each server are all level signals.

[0069] In one possible implementation, the power-on signal is the PowerCtrl signal, which is pulled low when the power button is pressed or when the BMC receives a power-on command. The power-off signal is the PowerCtrl signal, which is pulled low for 4 seconds when the power button is pressed for 4 seconds or when the BMC receives a power-off command. That is, transmitting the power-on signal involves pulling the corresponding GPIO port's level signal low, and transmitting the power-off signal involves pulling the GPIO port's level signal low for 4 seconds.

[0070] Similarly, the power-on and power-off status of the server can be the same as that of the PWRGD terminal of the power management chip 15. Different high and low levels indicate whether the server is powered on, that is, the CPLD pulls the level signal at the corresponding GPIO port low or high.

[0071] This embodiment provides a preferred solution that transforms the traditional software-based server collaborative power-on / off scheme, which relies on software polling and command issuance by a BMC, into a hardware-based scheme that uses GPIO to transmit high and low level signals between two CPLDs. Compared to the traditional software implementation, this hardware-based solution offers higher reliability and is less prone to failures that could prevent the server from coordinating power-on / off, thus improving server reliability.

[0072] Similarly, this application is not limited to the number of communication connections established between the main server CPLD12 and the pooling server CPLD14, but provides a preferred implementation scheme: the main server CPLD12 and the pooling server CPLD14 are connected by three independent GPIO communication connections, which are used to transmit power-on / power-off signals, the power-on status of the main server 11 and the power-on status of the pooling server 13, respectively.

[0073] As described in the above embodiments, the power-on / power-off signals, the power-on status of the main server 11, and the power-on status of the pooled server 13 are all transmitted as high or low level signals. These signals are transmitted between the two CPLDs via GPIO ports. By detecting the level status of the corresponding GPIO ports, the CPLDs can determine the power-on status of the main server 11 and the pooled server 13, and whether a power-on or power-off operation is required. Furthermore, the three independent GPIO ports ensure that these three signals do not interfere with each other, facilitating the smooth implementation of the coordinated power-on / off scheme provided in this application and further improving reliability.

[0074] This application provides a server collaborative power-on / off device. Based on existing main server CPLD and pooled server CPLDs, a communication connection is added between them. The PWRGD terminals of the power management chips of the remaining components of each server are connected to their respective CPLDs. This allows the CPLDs to determine the current power-on status of the server by monitoring the PWRGD terminals. Based on this connection, the main server CPLD and pooled server CPLDs can monitor and transmit the server's power-on status and power-on / off signals without a BMC, thus meeting the communication requirements for server power-on / off. Therefore, collaborative power-on / off of the main server and pooled servers can be achieved through hardware using only two CPLDs. Compared to current software-based solutions using a BMC for collaborative server power-on / off, this solution is not affected by BMC maintenance, and the hardware implementation is more stable than the software implementation, greatly improving the reliability of the server collaborative power-on / off solution. This helps protect the server from downtime due to abnormal power-on / off, extending the server's lifespan.

[0075] In view of the server collaborative power-on / off device provided in the above embodiments, this embodiment also provides a server collaborative power-on / off method, applied to the above-mentioned device, which is divided into a main server CPLD and a pooled server CPLD on both sides. When applied to the main server CPLD side, as follows... Figure 2 As shown, this method includes:

[0076] S21: When a power-on signal is detected, the power-on signal is sent to the pooled server CPLD.

[0077] The purpose of step S21 is to facilitate the CPLD pooled server to perform the boot operation.

[0078] S22: Check if the power-on status of the pooled server returned by the pooled server CPLD is "powered on". If so, proceed to step S23.

[0079] S23: Perform the power-on operation.

[0080] Specifically, when the pooling server CPLD detects that the power management chip PWRGD of the pooling server and all other components of the pooling server are in a powered-on state, the power-on state of the pooling server is set to the powered-on state.

[0081] S24: When a shutdown signal is detected, perform a shutdown operation.

[0082] S25: Detect whether the power management chip PWRGD of the main server and other components of the main server is in a power-off state. If so, proceed to step S26.

[0083] S26: Send a power-off signal to the pooled server CPLD and set the main server's power-on status to the power-off state.

[0084] The purpose of step S26 is to cause the pooled server CPLD to perform a shutdown operation.

[0085] Furthermore, this embodiment also provides a preferred implementation scheme, such as... Figure 2 As shown, the above method also includes:

[0086] Step S22 also includes: if not, proceed to step S27.

[0087] S27: Latch pool server boot abnormal status to register.

[0088] Step S25 also includes: if not, proceed to step S28.

[0089] S28: Latch the master server shutdown abnormal state to the register.

[0090] The above embodiments lock the abnormal state into a register when the power-on failure of the main server or the pooled server causes the entire server collaborative power-on process to fail. This allows subsequent maintenance personnel to obtain abnormal power-on information through the register and troubleshoot the fault.

[0091] Meanwhile, there is another possible implementation scheme in which the register is connected to the BMC, so that the BMC can obtain the abnormal state when the coordinated power-on or power-off fails and take corresponding actions.

[0092] Similarly, when the application is used on the pooled server side, such as Figure 3 As shown, this method includes:

[0093] S31: When a power-on signal is received from the master server CPLD, a power-on operation is performed.

[0094] S32: Detect the power-on status of the pooled server and the power management chip PWRGD of the other components of the pooled server. If they are all in the power-on state, then set the power-on status of the pooled server to the power-on state.

[0095] The purpose is to enable the main server CPLD to perform the boot operation.

[0096] S33: When a shutdown signal sent by the master server CPLD is detected, check the master server power-on status returned by the master server CPLD.

[0097] S34: If the device is already powered off, perform a shutdown operation.

[0098] Specifically, when the main server CPLD detects that the power management chip PWRGD of the main server and all other components of the main server are in a powered-off state, the main server power-on state is set to the powered-off state.

[0099] Additionally, it should be noted that when transmitting power-on and power-off signals between the main server CPLD and the pooled server CPLD, a preferred implementation method is through transparent transmission. Transparent transmission, also known as pass-through transmission, is a method that, regardless of the content of the transmitted services, only transmits the content from the source address to the destination address without altering the service data, thereby further improving the reliability of server-coordinated power-on and power-off.

[0100] This application provides a server collaborative power-on / off method, offering a control scheme for the aforementioned server collaborative power-on / off device. When the server is collaboratively powered on, the master server CPLD first receives a power-on signal and sends it to the pooled server CPLD. Upon receiving the power-on signal, the pooled server CPLD controls the pooled server to power on and detects the power-on status. After successful power-on, it updates the power-on status so that the master server CPLD can detect it. Once the master server CPLD detects the pooled server's power-on, it controls the master server to power on, thus completing the entire collaborative power-on process. The collaborative power-off process is similar, achieved through a communication connection between the two CPLDs, using hardware to complete the collaborative power-off, which offers higher stability compared to software implementation. Furthermore, this method does not require the involvement of the BMC (Browser Control Center), thus preventing the collaborative power-on / off from becoming unavailable due to frequent BMC maintenance operations, ensuring normal server operation, and further improving the reliability of the collaborative power-on / off scheme.

[0101] The above embodiments illustrate the coordinated power-on / off scheme from both the main server CPLD and the pooled server CPLD. To more clearly illustrate the server coordinated power-on / off method provided in this application, this embodiment, in conjunction with examples, further explains the entire process by dividing it into a power-on process and a power-off process:

[0102] 1. Power-on process (e.g.) Figure 4 (as shown);

[0103] S41: The main server CPLD has received a power-on signal.

[0104] S42: The master server CPLD will pass the power-on signal to the pooled server CPLD.

[0105] S43: After receiving the power-on signal, the pooled server CPLD performs a power-on operation on the pooled server.

[0106] S44: The pooling server CPLD detects and updates the power-on status of the pooling server.

[0107] S45: The main server CPLD checks whether the pooled server is powered on. If yes, proceed to step S46; otherwise, proceed to step S47.

[0108] S46: The master server CPLD performs a power-on operation on the master server.

[0109] S47: Latch the abnormal power-on state to a register.

[0110] 2. Power-off process (e.g.) Figure 5 (as shown);

[0111] S51: The main server CPLD received a shutdown signal.

[0112] S52: The master server CPLD performs a shutdown operation on the master server.

[0113] S53: The main server CPLD detects whether the main server's power-on status is "power-off". If yes, proceed to step S54; otherwise, proceed to step S55.

[0114] S54: The master server CPLD will pass the shutdown signal to the pooled server CPLD.

[0115] S55: Latch the shutdown exception state to the register.

[0116] S56: After receiving the shutdown signal, the pooled server CPLD performs a shutdown operation on the pooled server.

[0117] S57: The pooled server CPLD detects and updates the power-on status of the pooled server.

[0118] The above embodiments have described a server collaborative power-on / off method in detail. This application also provides an embodiment of a server collaborative power-on / off device. It should be noted that this application describes the device embodiment from two perspectives: one based on functional modules and the other based on hardware.

[0119] From the perspective of functional modules, this embodiment provides a server collaborative power-on / off device, which is also divided into two types: one applied to the main server CPLD side and the other applied to the pooled server CPLD side. The device applied to the main server CPLD side is as follows: Figure 6 As shown, it includes:

[0120] The power-on signal sending module 61 is used to send a power-on signal to the pooled server CPLD when a power-on signal is detected, so that the pooled server CPLD can perform a power-on operation;

[0121] The main server power-on module 62 is used to detect the power-on status of the pooled server returned by the pooled server CPLD. If it is in the power-on state, the power-on operation is performed. Specifically, when the pooled server CPLD detects that the power management chip PWRGD of the pooled server and other components of the pooled server are all in the power-on state, the power-on status of the pooled server is set to the power-on state.

[0122] The main server shutdown module 63 is used to perform a shutdown operation when a shutdown signal is detected.

[0123] The power-off signal sending module 64 is used to detect the power-on status of the power management chip PWRGD of the main server and other components of the main server. If they are all in the power-off state, the power-off signal is sent to the pooled server CPLD and the power-on status of the main server is set to the power-off state so that the pooled server CPLD can perform the power-off operation.

[0124] Preferred options also include:

[0125] The abnormal state latching module is used to latch the abnormal power-on state of the pooled server to a register if the power-on state of the pooled server returned by the CPLD is not "powered on" after the power-on signal is sent to the pooled server CPLD; and to latch the abnormal power-off state of the main server to a register if the power-on state of the power management chip PWRGD of the main server and other components of the main server is not "power-off" after the power-off operation is performed.

[0126] Devices used on the CPLD side of pooled servers, such as Figure 7 As shown, it includes:

[0127] The pooled server power-on module 71 is used to perform a power-on operation when it receives a power-on signal sent by the master server CPLD;

[0128] The power-on status setting module 72 is used to detect the power-on status of the pooled server and the power management chip PWRGD of the other components of the pooled server.

[0131] Since the embodiments of the apparatus and the embodiments of the method correspond to each other, please refer to the description of the embodiments of the method for the embodiments of the apparatus, which will not be repeated here.

[0132] This embodiment provides a server collaborative power-on / off device, which is applied to both the main server CPLD side and the pooled server CPLD side. When the servers are collaboratively powered on, the main server CPLD's power-on signal sending module first receives the power-on signal and sends it to the pooled server CPLD. Upon receiving the power-on signal, the pooled server CPLD, through its power-on module, controls the pooled server to power on and uses a power-on status detection module to detect the power-on status and update it after successful power-on for monitoring by the main server CPLD. The main server CPLD, after detecting the pooled server's power-on through its power-on module, controls the main server to power on, thus completing the entire collaborative power-on process. The collaborative power-off process is similar, using a hardware-based communication connection between the two CPLDs, which offers higher stability compared to software implementations. Furthermore, this process does not require BMC involvement, thus preventing the collaborative power-on / off from becoming unavailable due to frequent BMC maintenance operations, ensuring normal server operation and further improving the reliability of the collaborative power-on / off solution.

[0140] This application provides a server collaborative power-on / off system, including a memory and a processor. When the processor executes a program stored in the memory, it can implement the following method: a server collaborative power-on / off method.

[0141] This embodiment provides a server collaborative power-on / off system. The processor executes a computer program stored in memory. When the servers are collaboratively powered on, the master server CPLD first receives a power-on signal and sends it to the pooled server CPLD. Upon receiving the power-on signal, the pooled server CPLD controls the pooled server to power on and detects the power-on status. After successful power-on, it updates the power-on status so that the master server CPLD can detect it. Once the master server CPLD detects the pooled server's power-on, it controls the master server to power on, thus completing the entire collaborative power-on process. The collaborative power-off process works similarly, using a hardware-based communication connection between the two CPLDs, which offers higher stability compared to software implementations. Furthermore, this scheme does not require the involvement of the BMC (Browser Control Center), thus preventing unavailability of collaborative power-on / off due to frequent BMC maintenance operations, ensuring normal server operation, and further improving the reliability of the collaborative power-on / off solution.

[0142] Finally, this application also provides an embodiment corresponding to a computer-readable storage medium. The computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps described in the above method embodiments (which may be a method corresponding to the main server CPLD side, a method corresponding to the pooled server CPLD side, or a method corresponding to both the main server CPLD side and the pooled server CPLD side).

Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, or all or part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and executes all or part of the steps of the methods described in the various embodiments of this application. The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

[0144] This embodiment provides a computer-readable storage medium. When the computer program stored therein is executed, it enables collaborative power-on of servers. First, the master server CPLD receives a power-on signal and sends it to the pooled server CPLD. Upon receiving the power-on signal, the pooled server CPLD controls the pooled server to power on and detects the power-on status. After successful power-on, it updates the power-on status so that the master server CPLD can detect it. Once the master server CPLD detects the pooled server's power-on, it controls the master server to power on, thus completing the entire collaborative power-on process. Collaborative power-off of servers follows the same principle, achieved through a communication connection between the two CPLDs in hardware, offering higher stability compared to software implementations. Furthermore, this scheme eliminates the need for a BMC (Browser Control Center), preventing unavailability during collaborative power-on due to frequent BMC maintenance operations, ensuring normal server operation, and further improving the reliability of the collaborative power-on scheme.
