Embodiment one:
as shown in fig. 1, the present embodiment provides a method for prolonging the output holding time of a server power supply, including the following steps:
s1: and monitoring the running state of the power supply through the server, and if the power supply is abnormal, identifying the abnormal type of the power supply.
S2: if the current server is powered off abnormally for a single power supply, an abnormal power supply is determined, a 12V bus of the server is started by issuing an instruction for releasing the backflow prevention limit through the abnormal power supply, power is supplied to the abnormal power supply through the 12V bus voltage of the server, and power failure processing is performed.
Specifically, for abnormal power failure of a single power supply, the processing procedure is as follows:
1. the power supply Alert signal is polled through the abnormal power supply internal communication bus, the abnormal power supply sends a command to the server to release the restriction of preventing backflow of the current of the 12V bus of the server, and the 12V bus of the server is started to backflow the current of the 12V bus of the abnormal power supply, so that the voltage of the 12V bus of the abnormal power supply is maintained at a high level.
2. The abnormal power supply continuously polls the power supply running state and various parameters and records the power supply running state and various parameters into a built-in power supply register.
3. After the state information data of 10 groups of abnormal power supplies are recorded through the power supply register, the state information data are transmitted to a preset server fault processing system through the CPLD communication bus.
4. And analyzing the power failure information through the server failure processing system, automatically judging the failure reason, and displaying the failure reason in the failure record of the server failure processing system.
5. The server 12V bus current anti-backflow limit is restored by the server fault handling system sending a command to the abnormal power source.
S3: if the current server abnormally fails to supply power to all power supplies, judging whether the power supply fault is a primary side fault, and if the power supply fault is not the primary side fault, starting a preset power supply input capacitor module to supply power to the server.
S4: and if the power failure is a primary side failure, controlling the discharge of an energy storage capacitor in the abnormal power failure power supply to prolong the high-level time of the voltage of the 12V bus of the server.
Embodiment two:
based on the first embodiment, the invention also discloses a method for prolonging the output holding time of the server power supply, wherein the server power supply adopts N+N configuration, under the configuration, the server power supply abnormality is divided into two situations of single power supply abnormal power failure and all power supply abnormal power failure, and specific processing modes are as follows for the two abnormalities:
1. assuming that a single power supply of the PSU0 is abnormally powered down, the internal communication bus of the PSU0 polls a power supply Alert signal indicating abnormal power failure, the PSU0 issues a 12V bus current prevention backflow limitation of a releasing server, the 12V bus is started to backflow 12V bus current in the PSU0, the 12V bus voltage in the PSU0 is maintained at a high level, normal communication of the PSU0 can be maintained after the Alert is abnormally alarmed, the PSU0 power supply continuously polls the power supply running state and various parameters and records the parameters into a power supply register, the register records 10 groups of PSU0 state information data and then is transmitted to a server fault processing system through a CPLD communication bus, and the server fault processing system analyzes the power supply fault information to automatically judge the fault reason and displays the fault reason in the server fault processing system fault record. Meanwhile, the server fault processing system issues an instruction to the PSU0 to restore the 12V bus current of the server to prevent backflow limitation, and the maintenance personnel wait for processing. After the reverse current limit of the 12V bus of the server is prevented from being recovered, the server monitors that the power supply configuration is in a non-redundant state, and in order to prevent the server key data from being lost due to abnormal power supply, the server fault processing system issues an emergency storage command for the server key data, and meanwhile, some unnecessary processing processes are turned off to reduce the system power consumption and reduce the risk of abnormal power supply of the server.
Therefore, the abnormal power-down power supply is supplied by the reverse current supply of the voltage of the 12V bus of the server to keep the communication of the abnormal power-down power supply normal by the power-down power supply to give a limit instruction for preventing reverse current to the 12V bus of the server, so that the problem that the power-down power supply 12V output can maintain the high level time of 60ms at the highest and can not finish repeated polling records of power supply information before and after the fault, and the server end can not receive complete and correct alarm information to guide maintenance personnel to make accurate actions is solved.
2. When all 2N power supplies configured by the server power supplies N+N abnormally lose power AC lost, the power supply input capacitance module is started to increase the high-level maintenance time of the voltage of the 12V bus of the server, and meanwhile, the standby power supply is timely led in to supply power to the server, so that the problem of abnormal shutdown of the system caused by the AC lost of the server is avoided. If the abnormal power supply is caused by a primary side fault, the power supply input capacitor module is started to supply power to the power supply module normally, the high-level time of the 12V voltage of the power supply is prolonged by starting the discharge of the internal energy storage capacitor of the abnormal power supply, so that the normal internal communication of the power supply is maintained to poll the power supply fault information and feed the power supply fault information back to the server quickly, meanwhile, the maintenance time is prolonged by means of the 12V bus voltage to ensure that the server can complete archiving of all key data, the risk of losing the key data of the server is avoided, and the safety and stability of the server are effectively improved.
Specifically, when all 2N power supplies are abnormally powered down in the configuration of the server power supply N+N, the internal communication bus of the power-down power supply polls an abnormal AC lost power warning signal of the power supply Alert signal, the AC lost power supply can issue a power supply input capacitance intelligent module to guide in a power supply instruction, and the input capacitance module supplies power to the power-down power supply to maintain the voltage of a 12V bus in the power supply at a high level. Meanwhile, the power supply register records abnormal AC lost power failure warning signal information data of the power supply Alert signal and then transmits the data to the server fault processing system through the CPLD communication bus, and the server fault processing system analyzes the power supply fault information to automatically judge that the fault is caused by the AC lost and waits for maintenance personnel to process the fault. Meanwhile, the server fault processing system issues a machine room server backup power supply starting instruction, and the machine room backup power supply temporarily supplies power to the server, so that the risk of power failure of the server due to AC lost is avoided.
If the abnormal power supply is caused by a primary side fault, the power supply input capacitor module is started to not normally supply power to the power supply module. When the power-down power supply internal communication bus polls the power supply Alert signal abnormal bit primary side fault alarm, the power supply 12V voltage high level time is prolonged by starting the discharge of the abnormal power supply internal energy storage capacitor, so that the power supply internal communication is maintained to normally poll the power supply fault information and quickly feed back to the server, meanwhile, the maintenance time is prolonged by means of the 12V bus voltage to ensure that the server can complete the archiving of all key data, the risk of losing the key data of the server is avoided, and the safety and stability of the server are effectively improved.
It can be seen that the above scheme can realize the extension of the power output maintaining time of the server.
