Description

Method, system, device and storage medium for detecting power failure of server power output

Technical Field

The present invention relates to the field of servers, and more particularly, to a method, system, device, and storage medium for detecting a power failure of a power supply output of a server.

Background

The Server system needs to read the values of various sensors (sensors) from the Server power supply (Server PSU) at any time in order to optimize the power management and regulation system. The read contents can be classified into voltage detection, current detection, temperature detection, power detection, fan detection, and the like. The server utilizes a BMC (baseboard Management controller) substrate Management controller to access the server power supply MCU through I2C Bus to obtain the values of various sensors. Wherein, the output values of the server power voltage and the current are read to know whether the server power reaches the current sharing. In one case of the server reading the power output, the output is still in the normal range 11.4V-12.6V, but the output current is zero (note: it is necessary to confirm that the server power is not in A + S mode). Because the scene that the server power supply outputs alarms OVP, UVP and OCP is not reached, the server power supply does not output any alarm. The power supply does not have any alarm at this time because the system still operates normally. This kind of scene is called "server power Output power failure (Zero Output Current)".

Under the condition that the power supply output of the server is powered off, the current is zero and is a legal output value because the voltage is still normally output and is within a normal range. The server system will not alarm, so the system operation and maintenance personnel can not know whether the power supply function of the server with zero output current is still normal. If it is true that the power supply with zero output current fails, the load will concentrate on the power supply which normally works, which will cause the service life of the power supply to be reduced, so that the reliability of the system is reduced, and most seriously, the system is down or off-line. Because the existing design does not have a server power output power failure warning mechanism, the server operation and maintenance personnel are usually reminded to get rid of the problem on site when the server power supply function is abnormal to alarm or the server is suddenly off-line, so that the loss is caused to the user of the server.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it is understood that "first" and "second" are only used for convenience of expression and should not be construed as limitations to the embodiments of the present invention, and the descriptions thereof in the following embodiments are omitted.

In a first aspect of an embodiment of the present invention, an embodiment of a method for detecting a power failure of a power output of a server is provided. Fig. 1 is a schematic diagram illustrating an embodiment of a method for detecting a power failure of a server power output according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:

s1, acquiring a current-sharing bus voltage of the server power supply, and determining the current running condition of the power supply according to the current-sharing bus voltage;

s2, determining the voltage and the output current of the current equalizing bus according to the current running condition and the output power of the power supply;

s3, acquiring the current actual output current of the power supply, and judging whether the current actual output current is zero or not; and

s4, responding to the current actual output current not being zero, and continuously comparing the current actual output current with the output current to determine whether the current actual output current is abnormal or not.

In order to improve reliability, the server adopts a power redundancy mechanism. The mechanism is that a plurality of identical power supplies are configured, the power supplies are used for load balancing, when one power supply fails, the other power supply can take over the work of the other power supply, and after the power supplies are replaced, the plurality of power supplies work cooperatively. The benefit of redundancy is to achieve high stability of the server system. When one or two power supplies lose functions or are not output for unknown reasons, the rest power supplies in the system can continuously run to provide power for the server system, so that the server is not down or shut down due to power factors.

The power supply realizing the redundancy function has a plurality of groups of currents which are output in parallel, so that the average distribution of the currents is quite important. Therefore, it is necessary to have a current equalizing or current balancing function to ensure balanced output of current of each power supply. The purpose of current sharing is not to allow the system power supply to operate under high load for a long time (more than 80% of full load), and the long-time high-load operation also causes the service life of the server power supply to be reduced, so that the reliability of the system is reduced.

In order to improve the efficiency of the power redundancy mechanism during light load or Standby, the server adopts an a + S mode (Active-Standby mode). For redundant power systems, the cold redundancy mode may be enabled by a PMBUS command. The power supply device set to PSU0 is set to ACTIVE power (ACTIVE PSU), and the other power supply devices may be set to STANDBY power (STANDBY PSU). When this mode setting is enabled, the ACTIVE PSU (ACTIVE power supply) will take all the output load, the other STANDBY PSUs (STANDBY power supplies) are in a + S mode, the power supply output (+12VDC) holds the voltage and stops supplying power, this function can change the command by PMBUS setting different Von/Voff currents. The output power supply output voltage and current are zero (+12VDC off) if the power supply device is in the a + S mode. The power supply set to the active mode can operate more efficiently at this time.

The so-called A + S mode is that in the N + N power supply system, CR/Cold Redundant pins are connected together on a user system board to realize the Cold redundancy function. For an N + N power system, AC or DC power alone may be used, and the cold redundancy mode may be enabled via PMBus. The master is used to set to ACTIVE mode and the slaves can be set to STANDBY mode. When this mode is set to OK, the ACTIVE power supply will take on all output loads, the other STANDBY power supply will be in sleep mode, outputting the hold voltage and stopping the power supply output. This function can be changed by setting different Von/Voff currents via the PMBus command. The power consumption of the PSU0/1/2 power supply in sleep mode should be less than 10W. In this case, there is a possibility that the output current is zero and the voltage exists, so that the situation needs to be eliminated. Or designing the Server PSU to enter the STANDBY mode completely in the A + S mode. At this time, the main outputs of the power supplies are all closed, and only the standby power supplies are continuously powered on. When the system is not started, the power supply is in the mode to achieve the purpose of saving power.

The current server power supply is divided into a PRIMARY Side (PRIMARY Side) MCU and a SECONDARY Side (SECONDARY Side) MCU according to different functions, wherein the functions of the power supply include converter switch control, fan control, LED control, monitoring, protection, communication, etc. are performed by the MCU. The current sharing and redundancy functions are controlled and implemented by a SECONDARY Side (SECONDARY Side) MCU.

In some embodiments, the method further comprises: the current-sharing pins of the server power supply are connected together so that the current-sharing buses of the power supply of the same server have the same voltage. Server power flow is provided with a DC level feedback power circuit through hardware. And the basis of loading or unloading is provided when the parallel operation is carried out. When in application, the pins (Ishare pins) of the PSUs are connected together to be used as the reference voltage of the current-sharing DC level of each machine.

There are many current sharing methods, and in the embodiment of the present invention, a "maximum current automatic current sharing method" architecture is adopted. Fig. 2 is a diagram illustrating a maximum current auto-equalizing architecture according to an embodiment of the present invention. This is an automatic and non-deliberate way to set the master and slave, i.e. in all power modules, if at a certain moment the output current of one module reaches the maximum value of all modules, then this module is defaulted as the master and the rest of the modules are defaulted as slaves. Their voltage error references are compared and corrected one by one. Because the main module is not determined deliberately in the N parallel modules, the final so-called primary module and secondary module are determined only according to the magnitude of the output current in the circuit operation process, and the module with the largest current is taken as the main module.

The method has the characteristics of good current sharing effect and easy realization of accurate current sharing. In specific use, if a current equalizing bus is short-circuited or one unit connected to the bus does not work, the voltage of the bus is reduced, so that the output voltage of each unit is reduced, even reaches the lower limit, and the fault is caused. When the current of a certain module rises to Io max, the output current of the current amplifier also reaches a limit value, and the output voltages of other units automatically drop. A redundant system can be formed, and the number of current sharing modules can be theoretically unlimited.

In some embodiments, the method further comprises: the voltage of the current-sharing bus is connected to the pins of the digital-to-analog converter of the secondary microprocessor to convert the voltage of the current-sharing bus into a current value. The reference voltage (current-sharing bus voltage) obtained by current sharing is connected to the pin of the secondary side MCU ADC (digital analog converter). The voltage of the current equalizing bus can be converted into a current scale value, and the current scale value can be used to assist in judging whether the current output value is correct or not.
