Problems solved by technology

There are many types of PSU power specifications that can be used with servers, such as 800W, 1600W, and 3000W. The current power-off processing mechanism cannot dynamically adjust the power consumption of the whole machine according to the power consumption of the PSU, which affects the utilization of PSU functions.

Embodiment 1

[0034] like figure 1 As shown, this embodiment provides a PSU abnormal power-down processing system, including CPLD103 (Complex Programmable Logic Device, complex programmable logic device), CPU104, BMC102 (Baseboard Management Controller, baseboard management controller), PCH105 and at least one PSU101 (Power SupplyUnit, power supply).

[0035] Each PSU101 is connected to CPLD103 and BMC102 respectively; BMC102 is connected to CPLD103 and PCH105 respectively; CPU104 is connected to CPLD103 and PCH105 respectively.

[0036] BMC102 detects the total power consumption of all PSU101, according to the total power consumption of PSU101, controls the triggering of CPU104 throttling pin through CPLD103, and sets the upper limit of power consumption of CPU104 through PCH105.

[0037] Specifically, when the total power consumption of the PSU101 is greater than the preset power consumption value of the PSU101, the BMC102 outputs the first signal to the CPLD103, so that the CPLD103 cont...

Embodiment 2

[0042] like figure 2 As shown, this embodiment provides a method for processing abnormal power failure of a PSU based on the system of Embodiment 1. The method includes the following steps:

[0043] S1, BMC102 reads the total power consumption of all PSU101;

[0044] Specifically, BMC102 reads the total power consumption of all PSU101 through the I2C module.

[0045] S2. According to the total power consumption of the PSU101, the BMC102 controls the triggering of the throttling pin of the CPU104 through the CPLD103, and sets the upper limit of the power consumption of the CPU104 through the PCH105.

[0046] The step S2 specifically includes the following processes:

[0047] S2-1, when the total power consumption of PSU101 is greater than the preset power consumption value of PSU101, BMC102 outputs the first signal to CPLD103, so that CPLD103 controls CPU104 throttling pin is not triggered; at the same time, BMC102 will read the current total power consumption of PSU Trans...

Embodiment 3

[0055] Based on the second embodiment, this embodiment provides a device for processing abnormal power failure of a PSU, which is configured on the BMC 102 and includes the following functional units.

[0056] (1) PSU total power consumption reading unit: read the total power consumption of all PSU101.

[0057] The PSU total power consumption reading unit reads the total power consumption of all PSU101 through the I2C module.

[0058] (2) Throttling pin trigger unit: according to the total power consumption of PSU101, control the triggering of CPU104 throttling pin through CPLD103.

[0059] When the total power consumption of PSU101 is greater than the preset power consumption value of PSU101, the throttling pin trigger unit outputs the first signal to CPLD103, so that CPLD103 controls the CPU104 throttling pin not to be triggered, and the power consumption of the whole machine will not drop to the preset value PSU101 power consumption value below.

[0060] When the total po...

Abstract

The invention discloses a PSU abnormal power-down processing system, method and device, including CPLD, CPU, BMC, PCH and at least one PSU; each PSU is connected to CPLD and BMC respectively; BMC is connected to CPLD and PCH respectively; CPU is connected to CPLD respectively , PCH connection; BMC detects the total power consumption of all PSUs, according to the total power consumption of the PSU, controls the triggering of the CPU throttling pin through the CPLD, and sets the upper limit of the CPU power consumption through the PCH. The invention realizes the logic control of the power consumption of the whole machine when the output of the PSU is abnormal through the intercommunication and cooperation of the BMC, the PCH and the CPLD. According to the maximum power that the current PSU can provide, the power consumption of the whole machine is dynamically adjusted, so that the power supply of the PSU can be maximized.

Description

technical field [0001] The invention relates to the field of PSU abnormal power failure, in particular to a PSU abnormal power failure processing system, method and device. Background technique [0002] With the advancement of science and technology, servers have been widely used in many fields. At the same time, users continue to put forward higher requirements for the performance of servers. A high-performance server generally requires multiple PSUs to supply power to ensure that the server can achieve and continue to run stably in the best state. [0003] Usually, in order to ensure that the server can be used normally on the client side, a series of test items will be carried out on the server before shipment, and the purpose of the test is mostly to simulate problems that may occur during use by customers. During the test, it is often necessary to power on / off the server, but sometimes one or more of the PSUs may experience a power failure due to repeated plugging and ...
