Embodiments of the invention

The present invention provides a method for managing the power of the chassis, which is provided in the related art, because the power of the power supply of the chassis is insufficient.

Step 11: Obtain the board information and power information in the entire chassis.

Step 12: Obtain a power-off instruction on the board according to the information about the board and the power information.

Step 13: Control the power-on and power-off of the corresponding boards according to the power-off command on the board.

The management method of the power supply of the chassis provided by the embodiment of the present invention manages the power supply by controlling the power-on and power-off of the corresponding boards according to the information of the board and the power information in the entire chassis, so that the power consumption of the system is adjusted according to the system power consumption. Powering on and off, solves the problem that the chassis is unstable due to insufficient power supply of the chassis; it can prevent overcurrent of the power supply, and control some slots without powering up, which can save power for the system, thereby achieving system protection and green. The effect of energy saving and environmental protection.

The board information includes the in-position status of the board, the type of the board, and the rated power of the board. The board is in the in-position state, the board is in the power-off state, and the board is powered on. Electricity The source information includes the in-position state (up-and-down state) of the power supply, the communication state, the running state, the input power, and the power capacity; and the power can be queried only when the communication state between the power source and the main control board of the chassis is normal. Information, operating status includes the output voltage value of the power supply, the output current value, and the abnormal status alarm information.

Only when the power supply is online and the power communication state and the power running state are normal, it is determined that the power is available, and the power (input power and power capacity) of the power source can be accurately judged and calculated.

To ensure the stability of the power supply system of the chassis, multiple power supplies are usually configured on each chassis. The power that each power supply can provide is fixed, so when multiple power supplies are online, more boards can be powered. Therefore, obtaining the in-position state of the power supply is the basis for implementing intelligent management of the power source.

Optionally, the step of obtaining a power-off command on the board according to the board information and the power information includes: obtaining power consumption of the whole machine, system reserved power consumption, and system online peripheral power according to the board information and power information. The power consumption of the system is calculated by using the power consumption of the whole system, the power reserved by the system, and the power consumption of the system's online peripherals. The power-off instructions on the board are obtained according to the information about the board and the available power consumption of the system.

The power consumption of the whole machine is the product of the number of available power sources and the power consumption value of a single power source. The reserved power consumption of the system is the product of the number of main control boards and the power consumption value of a single main control board, and the number of switching boards. The sum of the power consumption value of a single switch board and the product of the number of fan boards and the power consumption of a single fan board. The power consumption of the system's online peripherals is the main control board (MPU), switch board (SFU), and fan board. The sum of the power consumption values of the devices that are powered on in place outside the (FAN); that is, the power consumption of the whole machine = the number of available power sources × the power consumption value of a single power source, wherein the backup power source is also an available power source;

The system reserves power consumption = number of MPUs × MPU power consumption + number of SFUs × power consumption + number of FANs × power consumption;

The system online peripheral power consumption is equal to the sum of power consumption values of the devices that are powered on in the system other than the MPU, SFU, and FAN;

The system available power consumption = the system power consumption - the system reserves power consumption - the system online peripheral power consumption.

The management method provided by the embodiment of the present invention provides two countermeasures in consideration of the newly inserted single board and the power supply. The first one is: obtaining the board according to the board information and the available power consumption of the system. The step of the power-off command includes: obtaining a power rating of the board to be powered on; if the power rating is greater than the power consumption of the system, obtaining an instruction that the board to be powered is not powered; if the power rating is less than or equal to When the power consumption of the system is available, the power-on-board command is obtained, that is,

Obtain the maximum required power consumption value of the newly inserted board, compared with the maximum available power consumption value that the system can provide. If the maximum power consumption value of the newly inserted board is less than the maximum available power consumption value that the system can provide. Then, the new plug-in board is powered on. Similarly, if the maximum power consumption value of the newly inserted board is greater than the maximum available power consumption value that the system can provide, the system power is not supported. The board is therefore determined to not power up the newly inserted board.

The second step of obtaining a power-off command on the board according to the board information and the available power consumption of the system includes: obtaining a power capacity of the power source whose power information is changed; and calculating, according to the power capacity and the available power consumption of the system The available power consumption of the system after the power supply is changed; the power-off command on the board is obtained according to the information about the board and the power consumption of the system after the power supply is changed.

The power supply changes include the uplink, the offline, and the abnormal. When the changed power information indicates that the power is online, the steps of obtaining the power-off command on the board according to the available power consumption of the system after the board information and the power supply change include: obtaining the in-position The rated power and type of the power-down state board; the in-position power-down status board that finds the power consumption of the system after the power supply is changed is less than or equal to the power-on state status board obtained in the first search; The board in the board again searches for the in-position power-down state board with the higher priority; in the in-position power-down state board obtained in the second search, the system has a smaller difference in the available power consumption of the system after the power supply is changed. The board is powered off. The board is powered on according to the third lookup.

After the changed power supply information indicates that the power supply is offline or abnormal, and the available power consumption of the system is negative, the steps of obtaining the power-off command on the board according to the board information and the power consumption of the system after the power supply change include : obtaining the rated power and type of the board in the power-on state; searching for the in-position power-on state board whose rated power is greater than or equal to the absolute value of the available power consumption of the system after the power source is changed; The in-place power-on state board again searches for the in-position power-on state board with the lower priority; the power consumption of the system after the power-on status check is obtained in the second power-on board. The on-board power-on state board with the smaller absolute value difference; the board is powered on according to the third lookup.

The changed power supply information indicates that the power supply is offline or abnormal, but the system can be used after the power supply is changed. If the power consumption is still non-negative, you do not need to power off the board.

The above measures for the power supply fluctuation are: obtaining the power supply in-position information, and making a decision on the state of the power supply in place. When a group of power supplies is newly online, the available power of the system is recalculated, and the board is already in the power-off state. The maximum power consumption value is compared. If the available power of the system is greater than the required maximum power consumption of the board in the power-off state, the board is powered off. When a group of power supplies is offline (offline or offline) If an abnormality occurs, the available power of the system is recalculated. The board with the lower priority and higher power consumption is judged by the board information, and then the type with lower priority and higher power consumption is given. The board is powered off to ensure that the other boards on the chassis are running properly when the power supply fails to provide sufficient power.

Step S03: If the power supply fails in the step S02, the system available power is recalculated.

Step S04: When the available power of the system is negative, the system selects that the service processing capability of the board is small (the type priority is lower, the rated power is greater than or equal to the absolute value of the available power of the system, and the difference between the absolute value of the available power of the system is small) The board is powered off and the other boards are working properly.

Step S05: If there is no fault in the power supply in the step S02, it is determined whether a new power supply is online. After the new power supply is online, the available power of the system increases.

Step S06: If there is a new power supply online in the step S05, the system available power information is recalculated.

Step S07: When the available power of the system is greater than the rated power of the board in the in-situ power-off state on the current chassis, the system selects a large-card service processing capability (the type has a higher priority, and the rated power is less than or equal to the available power of the system. Powering on the board with a smaller difference in the available power of the system can increase the total processing capacity of the chassis.

Step S08: If there is no new power supply on the line in the step S05, the power supply is stably operated. When it is done, the system will wait for the new board to go online.

Step S09: When the system detects that there is a new on-board line, the system can calculate the available power value of the system and the rated power value required by the new board. When the available power is greater than or equal to the rated power of the new board, step S11. As shown in the figure, when the available power is less than the rated power of the new online board, as shown in step S10, the new online board is not allowed to be powered.

It should be noted that the board type includes the main board type MPU, the service board type PFU, the switch board type SFU, and the fan board type FAN, which are in the in-position power-off state board mentioned in the embodiment of the present invention.
