Description
Technical Field
The present invention relates to the field of servers, and in particular, to a method, system, device, and storage medium for detecting power loss of a server power supply output.
Background
The Server system needs to read the values of the sensors from the Server power supply (Server PSU) at any time 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 obtains various sensor values by using the BMC (Baseboard Management Controller) baseboard management controller to access the server power MCU through the I2C Bus. The output value of the power supply voltage and the current of the server is read to determine whether the power supply of the server achieves current sharing. There is a case where the server reads the power supply 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 supply is not in a+s mode). Because the server power supply scenario for the output alarm OVP, UVP, OCP is not reached, the server power supply will not have any output alarm either. Because the system is still operating normally, the power supply does not have any alarm at this time. This scenario is referred to as "server power output power down (Zero Output Current)".
Under the condition that the power supply output of the server is powered down, the current is zero and is a legal output value because the voltage is still normally output and is in a normal range. The server system will not alarm, so the system operation staff can not know whether the server power supply function with zero output current is still normal. If the output current is zero, the load is concentrated to the power supply which works normally, the service life of the power supply is reduced, the reliability of the system is reduced, and the system is seriously damaged or offline. Because the existing design does not have a "power failure output" alarm mechanism, the server operation and maintenance personnel can be reminded to get to the site to eliminate the problem until the server power supply is abnormally functioned or the server is suddenly offline, 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 will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the embodiments of the present invention, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are merely used for convenience of expression, and should not be construed as limiting the embodiments of the present invention, and the following embodiments are not described one by one.
In a first aspect of the embodiment of the present invention, an embodiment of a method for detecting a power failure of a power supply output of a server is provided. Fig. 1 is a schematic diagram of an embodiment of a method for detecting power failure of a server power supply. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, acquiring 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 current sharing busbar voltage and the output current 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
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.
In order to improve the reliability, the server adopts a power redundancy mechanism. The mechanism is to configure a plurality of identical power supplies, load balance is carried out by the power supplies, when one power supply fails, the other power supply can take over the work immediately, and after the power supply is replaced, the power supplies work cooperatively. The benefit of redundancy is that high stability of the server system is achieved. When one or two power supplies are out of function or are not output for unknown reasons, the rest power supplies in the system can continuously operate to provide power for the server system, so that the server is not down or shut down due to power supply factors.
The power supply realizing the redundancy function has multiple groups of current to be output in parallel connection, so that the average distribution of the current is important. Therefore, the current equalizing or current equalizing function is required to ensure the current equalizing output of each power supply. The purpose of current sharing is to prevent the system power supply from being operated under high load for a long time (more than 80% of full load), and the service life of the server power supply is reduced due to long-time high-load operation, so that the reliability of the system is reduced.
In order to improve the efficiency of the power redundancy mechanism in light load or Standby, the server may adopt an a+s mode (Active-Standby mode). For redundant power supply systems, the cold redundancy mode may be enabled by a PMBUS instruction. Letting the power supply device set to PSU0 be set to ACTIVE power (ACTIVE PSU), the other power supply devices may be set to STANDBY power (STANDBY PSU). When this mode setting is enabled, ACTIVE PSU will take on all output loads, the other STANDBY PSU is in a+s mode, the power output (+12 VDC) holds the voltage and stops powering, this function can change the command by PMBUS setting different Von/Voff currents. If the power supply device is in the A+S mode, the output power supply output voltage and current are zero (+12VDC to stop the power supply). The power supply set to the active mode at this time can be operated with higher efficiency.
The A+S mode is to connect the CR/Cold redundancy pins together on the user system board in the N+N power supply system to realize the Cold redundancy function. For an n+n power supply system, either AC or DC power may be used alone, and the cold redundancy mode may be enabled by PMBus. The master power supply 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 over all output loads, and the other STANDBY power supply will be in sleep mode, outputting a hold voltage and stopping the power supply output. The function can be changed by setting different Von/Voff currents through PMBus commands. 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 voltage, and therefore, it is necessary to exclude the case. Or the Server PSU is designed to enter STANDBY mode completely in the A+S mode. At this time, the main power is turned off, and only the standby power is continuously turned on. When the system is not started, the power supply is in the mode so as to achieve the purpose of saving electricity.
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 by the MCU to complete the functions of switch control, fan control, LED control, monitoring, protection, communication, etc. of the power supply. The current sharing and redundancy functions are controlled and realized by a SECONDARY Side (SECONDARY Side) MCU.
In some embodiments, the method further comprises: and connecting the current sharing function pins of the power supplies of the servers together so that the current sharing bus voltages of the power supplies of the same server are the same. The current sharing of the server power supply is to provide a DC level feedback to the power supply circuit through a hardware. And provides the basis for loading or unloading when in parallel operation. When in use, the PSU current sharing function pins (Ishare pins) are connected together to be used as the reference voltage of the current sharing DC level of each machine.
There are many methods for current sharing, and in the embodiment of the present invention, a "maximum current automatic current sharing method" architecture is adopted. FIG. 2 is a diagram of a maximum current automatic current sharing method according to an embodiment of the present invention. This is an automatic, unintentional method of setting the master and slave, i.e. in all power supply modules, if at a certain moment the output current of one module reaches the maximum of all modules, this module is defaulted as master and the remaining modules are defaulted as slaves. Their voltage error references are compared and corrected one by one. Since the primary module is not intentionally determined among the N parallel modules, the final so-called primary and secondary modules are determined according to the magnitude of the output current only during the operation of the circuit, and the module with the largest current is taken as the primary module.
The method has the characteristics of good current sharing effect and easy realization of accurate current sharing. In a specific use, if a current sharing bus short circuit occurs or one unit connected to the bus is not working, the voltage of the bus is reduced, so that the output voltage of each unit is reduced, even the lower limit is reached, and the fault is caused. And when the current of a certain module rises to Iomax, the output current of the current amplifier also reaches a limit value, and the output voltage of other units is automatically reduced. The redundancy system can be formed, and the number of the current sharing modules is not limited in theory.
In some embodiments, the method further comprises: the current-sharing bus voltage is connected to the digital-analog converter pin of the secondary microprocessor to convert the current-sharing bus voltage into a current value. The reference voltage (current-sharing bus voltage) obtained by current sharing is connected to the pin of the secondary MCU ADC (digital-to-analog converter). The current equalizing bus voltage can be converted into a current scale value, and the current scale value can be used for assisting in judging whether the current output value is correct or not.
Taking a server power supply with 1600W power output as an example, a maximum of 4 power supplies are set in parallel. FIG. 3 is a table showing the comparison of 1600W power supply current sharing bus voltage and output power.

The iv.4 PSUs are output in parallel at a maximum of 6400W. The current sharing bus voltage is 6-8V, the maximum output current is 533A, and the current sharing of each PSU is still about 133A (the maximum output current of a single PSU is still not exceeded).
And acquiring the 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.
In some embodiments, the determining the current operating condition of the power supply according to the current share bus voltage includes: determining that the current operation condition of the power supply is single power supply operation in response to the current equalizing bus voltage being in a first interval; and determining that the current operation condition of the power supply is that a plurality of power supplies are operated in parallel in response to the current flow equalizing bus voltage being in other intervals. According to the relation between PSU and output power and current during current sharing, the current running condition of the power supply can be determined according to the current sharing bus voltage (Ishare Bus voltage):
ishare Bus voltage =0.25-2V, operating as a single PSU.
Ishare Bus voltage =2-4V, two PSUs running in parallel.
Ishare Bus voltage =4-6V, running in parallel for three PSUs.
Ishare Bus voltage =6-8V, four PSUs running in parallel.
And determining the current sharing busbar voltage and the output current according to the current running condition and the output power of the power supply.

And acquiring the current actual output current of the power supply, and judging whether the current actual output current is zero. In response to the present actual output current not being zero, the present actual output current is continuously compared with the output current to determine whether an anomaly is present.
In some embodiments, the method further comprises: responding to the current actual output current being zero, inputting an instruction by using an IPMI tool and acquiring current output information of a server; and responding to the register value in the current output information as a preset value, and alarming. The instruction set D1h-D3h in the PMBus1.2 instruction set is reserved for function expansion. D1h can be taken as the definition and expansion of the power-down function of the power output of the server. The server BMC can obtain the current output information of the server by inputting an instruction D1h by using the IPMI tool. At this time, the receiving command is a SECONDARY Side (SECONDARY Side) MCU, and returns a Hex value (hexadecimal) to display the current output state. If 00h is displayed to indicate that PSU output is zero, a warning needs to be given; if 02h is shown to indicate that the PSU average flow rate is below 5%; if 04h is shown to indicate that the PSU average flow rate is below 10%; if 06h is shown, it indicates that the PSU average flow rate is above 10%.

The secondary side MCU converts the warning pin of the server power supply device from a high level to a low level. At this time, the Server BMC receives the signal and sends out the Server PSU Server maintenance personnel to check the power state. At this time, the LED warning of the Server PSU is changed from green light to amber light, and the Server PSU needs to be replaced. The following table is a Server PSU LED light table:
