Description

TECHNICAL FIELD

[0001] The present specification relates to the technical field of communication, and particularly relates to a power control method and device, equipment and a readable storage medium. BACKGROUND

[0002] As a key link of hardware quality verification, power reliability test is directly related to the performance of the equipment in the scene of unexpected power failure, power grid fluctuation or power recovery. In the center deployment, the stability of power supply is not absolute, and sudden power failure or power supply anomaly occurs from time to time. Therefore, during the production test and equipment deployment stage, it is necessary to detect whether the server has the ability to automatically restart and recover normal service after power failure, which is one of the important indicators for measuring high availability.

[0003] In order to simulate the power interruption situation, the industry generally adopts AC power cycle test. By artificially cutting off the AC power input of the server, then restoring the power supply, it is observed whether the server can complete the whole process of power down, power up, self-check, starting operating system and service recovery. This process not only verifies the tolerance and recovery mechanism of the key hardware such as power module, mainboard and BMC (baseboard management controller), but also verifies the consistency of data before and after power failure, the integrity of file system and the automatic recovery ability of key service.

[0004] AC power-off restart test usually relies on external auxiliary equipment to realize physical control of the server power supply. For example, a smart PDU (Power Distribution Unit) or AC switch device is used. Such devices can receive control instructions through a network interface and then perform power-on and power-off operations on the server power supply interface connected thereto, thereby simulating the interruption and recovery of alternating current power supply. Test personnel can remotely control the smart PDU through a script or an automated test platform to perform multiple AC restart operations on the target server in a predetermined time sequence to verify the stability of long-term operation. This external device-dependent solution has significant limitations. The smart PDU or AC switch itself is an additional hardware device that increases the overall cost of rack deployment, especially in large-scale test environments. Providing such devices for each test server or each batch of test servers will result in high capital investment and operational overhead. Secondly, this solution relies on the stability of network communication between the control end (such as the test client) and the smart PDU. Once the network is interrupted or the control end is down, the test process will be forced to interrupt, resulting in incomplete testing or data loss, affecting the reliability of the test results. Since the smart PDU is an external device and cannot sense the internal running state of the server in real time, for example, whether the operating system has been successfully started, whether the system self-checking is completed, or whether there is a startup exception, the power-off and power-on operations can only be performed based on the preset time interval, and there is no feedback mechanism for the actual state of the server.

[0030] The present specification provides a power supply control method, device, equipment and readable storage medium to at least improve one of the above technical problems.

[0031] Specific technical solutions are described below.

[0032] In an embodiment, the present specification provides a power supply control method applied to a PSU device of a server, the server further comprising a BMC device, the PSU device providing power supply for the BMC device and other components of the server, the method comprising: receiving a power supply restart instruction issued by the BMC device, the power supply restart instruction comprising a first delay time length and a second delay time length, and parsing to obtain the first delay time and the second delay time; waiting for the first delay time length, and executing power-off of the BMC device and power-off of the other components of the server; waiting for the second delay time length, and executing power-on of the BMC device and power-on of the other components of the server; the first delay time length is used for waiting for the BMC device and the other components of the server to start and load firmware; and the second delay time length is used for waiting for the BMC device and the other components of the server to complete power-off.

[0033] The PSU is a power conversion and distribution module, which receives and parses the advanced power supply control instruction from the BMC, accurately controls the on-off sequence of the main power and auxiliary power according to the timing parameters contained in the instruction, and realizes the full-cycle management of the power supply state of the entire server. The method is applied to a PSU device of a server, the server further comprising a BMC device, the PSU device providing power support for the BMC device and other components such as CPU, memory, hard disk, motherboard chipset, etc. In the traditional design, the auxiliary power output of the PSU always supplies power to the BMC to ensure that even if the server is in a shutdown state, the BMC can still be remotely managed through the network. This results in that the conventional remote restart operation cannot cut off the power supply of the BMC, and cannot simulate the real power-off scenario. The present embodiment breaks through this limitation by introducing a controllable auxiliary power cut-off mechanism through the PSU, so that the PSU can actively cut off all power outputs including the BMC power supply circuit under the instruction of the BMC.

[0034] Specifically, as Figure 1 comprise the following steps, which can be exchanged in order according to the needs of the actual application scene:

[0035] Step S11, receiving the power restart instruction issued by the BMC device, the power restart instruction containing a first delay duration and a second delay duration, and parsing to obtain the first delay time and the second delay time.

[0036] The BMC device issues a special power restart instruction to the PSU device. The instruction can not be a general power control command defined in the standard IPMI (Intelligent Platform Management Interface) protocol, but a special instruction format further extended in the embodiment, containing a first delay duration and a second delay duration.

[0037] As the out-of-band management core of the server, the BMC has independent firmware (such as HDM, H3C Device Management) and network interface, and communicates with the PSU through an internal bus (such as PMBus, Power Management Bus) during the operation of the server operating system or in the shutdown state. When the tester or the automated script sends an AC restart request to the BMC through SSH, Web interface or API, the BMC generates a corresponding power restart instruction. The power restart instruction is sent to the PSU through the PMBus protocol.

[0038] The microcontroller inside the PSU receives the instruction and first parses it to extract the specific values of the first delay duration and the second delay duration. The first delay duration is used to control the time interval from receiving the instruction to executing the power-down operation, and its purpose is to ensure that the BMC and other components of the server have enough time to complete the key startup processes such as saving the current state, loading firmware or system self-checking. For example, if the power-down operation is performed immediately after the server is powered on or the operating system is starting, it may cause data corruption or startup failure. Therefore, setting a reasonable first delay duration (such as 100 seconds, 300 seconds or longer) can ensure that the system is in a stable state before power-off, thereby ensuring the effectiveness of the test. The second delay duration is used to control the time interval from the completion of power-down to the re-power-on, and its role is to simulate the recovery delay after a real power grid failure, ensuring that the capacitor inside the PSU is fully discharged and the power module is completely cooled, thereby more realistically reproducing the electrical environment of AC restart. For example, setting a second delay duration of 10 seconds can avoid the "soft restart" phenomenon caused by residual voltage of the capacitor, and ensure that the next power-on is a complete cold start process.

[0039] Step S12, waiting for the first delay duration, and executing power-down of the BMC device and power-down of other components of the server.

[0040] The PSU starts an internal timer and begins waiting for the first delay duration. During this period, the PSU maintains normal power output and the server components continue to operate. When the first delay duration expires, the PSU performs the critical power-down operation: simultaneously cutting off the main power output that powers the motherboard devices (such as CPU, memory, hard disk, etc.) and the auxiliary power output that powers the BMC.

[0041] This operation is implemented by the power switch circuit (such as MOSFET array) inside the PSU, and the microcontroller sends a control signal to close the corresponding power channel. Since the auxiliary power is cut off, the BMC is also powered off, which means that the out-of-band management function of the server is temporarily interrupted, which is completely consistent with the real power-off scenario.

[0042] Step S13, wait for the second delay duration, and perform the power-on operation for the BMC device and the power-on operation for other components of the server.

[0043] After the power-down operation is completed, the PSU enters the second phase of the waiting period, i.e., waiting for the second delay duration. During this period, all outputs of the PSU are in the off state, and the server is completely powered off. The microcontroller inside the PSU can enter a low-power sleep mode or be completely powered off, relying only on the state information saved before instruction execution to maintain the timing logic. When the second delay duration expires, the PSU performs the power-on operation: re-enables the main power and auxiliary power outputs. The restoration of the auxiliary power first powers the BMC, allowing it to start and load the firmware; the restoration of the main power powers the CPU, memory, and other components, triggering the complete power-on self-test (POST) and operating system startup process of the server.

[0044] At this point, a complete AC restart cycle is completed. The PSU has the ability to independently complete the entire timing and power-on / off sequence without continuous external instructions. The BMC needs to be restarted after power-off, and its communication link with the PSU will also experience interruption and reconstruction.

[0045] In one scenario, a tester needs to perform an automated AC reboot test on a server running a Linux operating system. The test script is deployed within the server's operating system and initiates the test by invoking the ipmitool chassis powercycle AC 300 300 10 command. The "AC" flag in the command indicates that an AC reboot is to be performed, "300" represents the number of cycles, "300" is the first delay duration (in seconds), and "10" is the second delay duration (in seconds). When the command is executed, the operating system forwards the request to the BMC through the in-band IPMI interface. Upon receiving the request, the BMC verifies the parameters' legitimacy, generates a power reboot instruction containing the first delay of 300 seconds and the second delay of 10 seconds, and sends it to the PSU via PMBus. After parsing the instruction, the PSU starts a 300-second countdown. During this period, the server operates normally, and the test script can perform system state checks, log collection, and other operations. After 300 seconds, the PSU cuts off the main power and auxiliary power, and the server is completely powered off. After 10 seconds, the PSU powers up again, and the server starts. After the BMC reinitializes, it restores its connection to the management network. The test script automatically reconnects and records the results of this reboot after the operating system recovers. This process will be repeated 300 times to achieve long-term unattended reliability testing. Since the first delay duration is long enough, it ensures that the system has been running stably before each reboot, avoiding invalid tests caused by frequent reboots.

[0046] A separate microcontroller (MCU) is integrated inside the PSU, which has sufficient processing power and storage space to run the power management firmware. This MCU needs to be connected to the control circuits of the main power and auxiliary power, allowing it to independently control the switching state of each power supply. During power-off, the MCU can use the residual energy from the PSU input or a small backup battery to maintain the operation of the timing circuit, ensuring the accuracy of the second delay duration. The PSU also has a state feedback mechanism that can report the current power state (such as "normal power supply," "waiting for power-off," "powered off," "waiting for power-on," etc.) to the BMC via PMBus, allowing the BMC to monitor the state and record logs.

[0047] In one embodiment, the power reboot instruction contains a loop instruction; the method further comprises: according to the loop instruction, under the condition of waiting for the first delay duration and the second delay duration respectively, cyclically performing the steps of powering off the BMC device and other components of the server, and powering on the BMC device and other components of the server.

[0048] In one embodiment, after the step of waiting for the first delay duration, the method further comprises: detecting the current startup state, and feeding back an alarm log if an abnormal startup is detected.

[0049] In an embodiment, the power supply restart instruction issued by the BMC device is received through a PMbus channel.

[0050] In an embodiment, the present specification also provides a power supply control method applied to a BMC device of a server, the server further comprising a PSU device, the PSU device supplying power to the BMC device and other components of the server, the method comprising: issuing a power supply restart instruction to the PSU device, the power supply restart instruction containing a first delay duration and a second delay duration, and parsing to obtain a first delay time and a second delay time, the power supply restart instruction being used to make the PSU device execute power-off of the BMC device and power-off of other components of the server after waiting for the first delay duration, and execute power-on of the BMC device and power-on of other components of the server after waiting for the second delay duration; powering off in response to a power-off event of the PSU device to the BMC device; powering on in response to a power-on event of the PSU device to the BMC device, and loading the BMC firmware; the first delay duration being used to wait for the BMC device and other components of the server to start and load the firmware; and the second delay duration being used to wait for the BMC device and other components of the server to complete power-off.

[0051] Specifically, as Figure 2 , the following steps can be exchanged in order according to the needs of the actual application scene:

[0052] Step S21, issuing a power supply restart instruction to the PSU device.

[0053] The BMC device issues a structured power restart instruction to the PSU device, including two programmable time parameters, a first delay time and a second delay time. The instruction is sent to the PSU through the internal physical bus of the server (such as PMBus). The first delay time included in the instruction is designed to provide a sufficient startup and firmware loading window for the BMC and other components of the server (such as CPU, memory, hard disk, etc.). For example, after the server has just completed a power-on operation, the BIOS / UEFI firmware needs time for self-checking (POST), the operating system needs time to load the kernel and drivers, and the BMC itself also needs time to initialize its network interface, sensor monitoring module and management service. If the power-off operation is performed immediately during this process, it may not only cause the system to crash, but also damage the data on the storage device. Therefore, by setting a reasonable first delay time (such as 90 seconds, 300 seconds or longer), it can be ensured that the system has entered a stable and predictable state before power-off. The second delay time is used to control the time interval between power-off and power-on, which simulates the recovery delay after a real power grid failure, ensures that the high-voltage capacitor inside the PSU is fully discharged, and the temperature of the power module is reduced to a safe level, thereby avoiding "false restart" or hardware damage caused by residual voltage or thermal stress. A typical second delay time may be set to 5 to 10 seconds to meet the discharge requirements of most power supply designs.

[0054] Step S22, in response to the power-off event of the PSU device to the BMC device.

[0055] When the PSU receives the power restart instruction issued by the BMC, it parses the first delay time and the second delay time, and starts the internal timing mechanism. During the first delay time, the PSU maintains normal power output, and the components of the server operate normally. After the timing ends, the PSU performs the critical power-off operation: simultaneously cutting off the main power output for the motherboard device and the auxiliary power output for the BMC, which is exactly the same as pulling out the power cord. When the auxiliary power is cut off, the power supply of the BMC is interrupted, and its internal processor and circuit stop working, and all running processes and network connections are immediately terminated. This process realizes real AC restart and breaks the mode of BMC uninterrupted power supply. During the power-off period, the BMC is in a completely power-off sleep state and does not consume any energy or perform any functions.

[0056] Step S23, in response to the power-on event of the PSU device to the BMC device, and loads the BMC firmware.

[0057] When the second delay duration ends, PSU re-enables the output of the main power and the auxiliary power, and the server starts to power up again. At this time, BMC responds to the power up event of itself by PSU, and starts to boot from zero. First, the restoration of the auxiliary power supplies power to the microcontroller and the memory of BMC, which makes it out of the reset state. Then, BMC starts to load its firmware, performs a self-checking procedure, initializes the network controller, sensor interface and management services. This power up and firmware loading process is exactly the same as the starting procedure of BMC when the server is cold started, which ensures the authenticity of the test scenario. When the firmware of BMC is loaded and enters the normal operation state, it restores the management capability of the server, and can receive new instructions through the network interface or report the status of the restart completion to the monitoring system.

[0058] In one implementation scenario, consider an automated reliability test environment. A newly designed server needs to be tested for AC restart endurance for 72 hours, and 1000 complete AC restart cycles are planned to be performed. The traditional method needs to configure expensive intelligent PDU and dedicated control server, and there is a risk of network interruption leading to test failure. Using the method of the embodiment, only the instruction similar to "ipmitool chassis power cycle AC 1000 90 8" needs to be input through the HDM Web interface or command line tool of the server. After the instruction is parsed by BMC, BMC generates a power restart instruction containing a first delay of 90 seconds and a second delay of 8 seconds and sends it to PSU. PSU cuts off all power after 90 seconds and powers up again after 8 seconds. Since the whole process is completed autonomously by BMC and PSU inside the server, no external intervention is needed, and even if the management network is interrupted for a short time during the test, it will not affect the execution of the restart sequence. BMC automatically records the number of restarts, timestamps and system status after each restart, and generates a complete log report at the end of the test. This embedded automatic test capability greatly improves the test efficiency and reliability.

[0059] In one implementation, the power restart instruction contains a cycle instruction; the power restart instruction is further used to make the PSU device cyclically execute the steps of powering down the BMC device and other components of the server, and powering up the BMC device and other components of the server according to the cycle instruction under the condition of waiting for a first delay duration and a second delay duration respectively each time.

[0060] In one implementation, the power up and load BMC firmware in response to the power up event of the PSU device to the BMC device further include: detecting and / or obtaining startup abnormities of components of the server, generating and / or obtaining alarm logs; the components of the server include the PSU device, the BMC device and other components of the server.

[0061] In an embodiment, the power supply restart instruction is issued to the PSU device through a PMbus channel.
