Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification.
The present application provides a power management method, as shown in fig. 1, including:
s100, determining the residual power of the server according to the total power of the power supply provided by the power supply in the server and the occupied power of the current component.
As shown in fig. 2, the server may include an OM, a plurality of functional nodes, a power supply, a fan, and other components, where Management devices such as a BMC (Baseboard Management Controller) and a BIOS (Basic Input Output System) chip are disposed on the functional nodes, the BMC is configured to detect states of the devices on the functional nodes and control operations such as powering on and powering off of the functional nodes, and the BIOS chip is configured to implement a self-check and a start process of the functional nodes. The functional nodes can be computing nodes, storage nodes, interconnection nodes and the like plugged into the server. And the interconnection node is used for realizing data interaction between the storage node and the computing node in the server and interaction between the computing node and external equipment (such as a switch, other servers and the like).
In a server, total power = the number of power supplies × the power of a single power supply × X%, where X denotes a redundancy coefficient, and is set to range from 0 to 100, which may be set according to actual requirements, for example, may be set to 90%, that is, 10% of power is reserved.
The occupied power of the current component = fixed power + power-on power;
the fixed power = OM maximum power + fan maximum power + functional node BMC power + basic IO power;
the power-on power = processor + display card + memory + single-board base power.
Based on the formula, the numbers of the OM, the functional nodes, the fans and the power supply are not unique, and calculation can be carried out according to actual deployment.
Because the server has a power supply strategy, part of the power supplies can be in a power supply state and part of the power supplies can be in a backup state according to the power supply strategy. For example, the power supply strategy at least comprises N + N, N +1 and no redundancy. The form of N +2, N +3 … N + (N-1) and the like can be set according to actual needs, and the form is not limited.
The OM can determine the number of power supplies in the power supply state and the power that can be provided by collecting information of the power supplies, thereby determining the total power of the power supply.
When the server is in a working state, the OM performs interaction of heartbeat messages with the functional nodes in the server. Through the interaction heartbeat message, on one hand, whether the functional node has a fault can be determined, on the other hand, the heartbeat message can carry the current power of the functional node, and the OM can analyze the power-on power of one functional node from the load by receiving the heartbeat message. And then, the occupied power of the current component can be calculated through the fixed power and the power-on power of the plurality of functional nodes. Then, OM can determine the remaining power of the server, and the current remaining power is the difference between the total power of the power supply and the occupied power.
S101, if the functional node is detected to be inserted into the server, the required power of the functional node is obtained.
In the server, as shown in fig. 2, a slot into which a functional node is not inserted may be included. In order to improve the working efficiency of the server, a new functional node can be inserted into the slot.
After the functional node is inserted into the slot, the BMC of the functional node is powered on to manage the power-on process of the functional node. And activating a BIOS chip through the BMC to perform self-checking, collecting the power of each component of the functional node, and summarizing to form the required power of the functional node.
And after the OM determines the required power of the functional node and the residual power of the server, determining subsequent execution according to the magnitude relation of the required power and the residual power of the server. If the required power is less than the residual power, the OM can directly issue a power-on instruction to the BMC, so that the BMC controls the functional node to be powered on. If the required power is not less than the remaining power, it indicates that the newly inserted functional node may not be powered up normally, and step S102 is executed.
And S102, if the required power is determined to be not less than the residual power, switching at least part of standby power in the server into a power supply according to a preset power supply strategy, and recalculating the residual power until the residual power is greater than the required power.
Since a plurality of power supply strategies can be configured at the server, and the power supply strategies can be divided into certain levels, namely, the power supply strategies are arranged in descending order from the top to the bottom according to the number of the adopted standby power supplies, for example, when the power supply strategies comprise N + N, N +1 and no redundancy, the number of the adopted standby power supplies which can be N + N is N, the level is the highest, and the level of the non-redundancy is the lowest after N + 1. When the server works, the power supply strategy is selected from high to low according to the level, namely, the power supply strategy is preferentially set to be N + N.
When the required power is determined to be not less than the residual power, the OM may determine that the server cannot power up the newly inserted functional node. At this time, because the standby power supply still exists in the server, the OM may change the power supply policy currently selected by the server, and select the N +1 power supply policy of the first-level priority, that is, switch more standby power supplies to the power supply, so as to provide more power.
And after the OM switches the standby power supply to the power supply, the OM detects the increase of the power supply and recalculates the residual power.
At this time, if OM determines that the remaining power is greater than the required power, step S103 may be skipped to, and the functional node is started to complete the power-on process. If the OM determines that the remaining power is still not greater than the required power, the OM continuously adjusts the power supply strategy under the condition that the standby power still exists in the server, and switches more standby power supplies into the power supply so as to increase the amount of the remaining power to meet the requirement of the newly inserted functional node.
S103, starting the functional node inserted into the server.
By adjusting the power supply strategy, the standby power supply is switched to the power supply to increase the residual power of the server, so that the situation that the residual power cannot meet the required power at the time point when the functional node is inserted into the server can be avoided, the newly inserted functional node is directly refused to be powered on, the power control of the server is more flexible, and the reliability of the server is improved.
Optionally, after the step S102, switching at least part of the standby power supply in the server to the power supply, the method further includes:
and S104, if the power supply strategy is set to be non-redundant and the required power is greater than the residual power, sequentially recovering the distributed power of the electrified functional nodes in the server from low to high according to the priority of the components, and recalculating the residual power until the residual power is greater than the required power.
If the power supply strategy of the server is already adjusted to the lowest level (i.e. no redundancy), it indicates that there is no backup power source that can be switched to the power supply source in the server, and the remaining power in the server cannot be continuously increased. If the residual power of the server still cannot meet the required power of the functional node, the power-on process of the functional node can be terminated only, and the operation of a worker is waited.
Because the newly inserted functional node needs to complete the power-on process, when the power supply and the standby power supply cannot meet the requirements, the OM can recover partial power from the currently running component to meet the power requirement of the newly inserted functional node.
The priority of the components may be configured in the OM in advance, or may be configured by the system guiding the staff after the server operates.
For example, in the following, taking an interconnection node included in a server as an example, an OM may configure a priority order according to a serial number of the interconnection node, and take 6 interconnection nodes as an example, configure slot numbers 1 to 3 as a high priority, and slot numbers 4 to 6 as a low priority, where the reason for this is that the interconnection node is set as a master, that is, 1 to 3 are master, and 4 to 6 are slave, and therefore, the OM may recover power of a part of the slave interconnection nodes.
In another way, taking the compute node and the storage node as examples, the priority order may also be set, and taking 16 nodes as examples, slot numbers 1-8 may be set as high priority, and slot numbers 9-16 may be set as low priority.
Of course, the setting of the component priority is not limited to this, and other components may be set for power recovery.
Optionally, after determining that the required power is not less than the remaining power in step S102, the method further includes:
and S105, reporting the alarm information and recording an abnormal log.
Since there is still a certain abnormality in practice by switching the standby power supply to the power supply, the OM still notifies the worker to perform the repair in response to the above-mentioned warning message.
In addition, by recording the abnormal log, the worker can inquire the time and reason for discovering the abnormality.
Correspondingly, the present application provides a power management apparatus, as shown in fig. 3, including:
the operation unit is used for determining the residual power of the server according to the total power of the power supply provided by the power supply in the server and the occupied power of the current component, wherein the current residual power is the difference value of the total power of the power supply and the occupied power;

and the alarm unit is used for reporting alarm information and recording an abnormal log.
