Detailed Description
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
The management of server power consumption is particularly important, and especially with the development of big data, a large number of hard disks are applied more frequently in a data center, and the adjustment and control of the power consumption of the hard disks become more and more important.
The power consumption limit in an operation and maintenance machine room is often certain, in order to avoid an excessive power consumption peak value or save cost, the power consumption limit is often set for each server in the operation and maintenance of the server, and the mature method in the industry is to perform power consumption limit on key components such as a CPU and a memory, but the power consumption limit of a hard disk is relatively deficient. The power consumption of the hard disk storage subsystem in a server or storage is more and more important, and how to limit the power consumption of the hard disk storage subsystem is a difficult problem in the industry.
In the application, it is considered that the division of the storage hard disks is generally different on the server, and if some hard disks are used for frequently exchanging data and some hard disks are used for storing cold data which is accessed infrequently, the rate requirement of the IO processing is different for each hard disk. In the current power consumption limiting scheme, the power consumption limit values of each hard disk in the server are generally the same, and the power consumption limits of the hard disks are indiscriminately limited, so that the power consumption limit values of the hard disks which are frequently accessed cannot be improved, so that the IO performance is insufficient, the access rate is affected, the power consumption limit values of the hard disks which are not frequently accessed are far higher than the required power consumption limit values, and the power consumption of the hard disks is unbalanced. Under the condition of certain rated power consumption, the normal operation of the service is not influenced, the purpose of saving power consumption can be achieved, and the intelligent dynamic balance regulation and control of the power consumption of each hard disk is very important.
Therefore, the embodiment provides a dynamic power consumption balancing method for a server hard disk, which performs dynamic balancing adjustment on the power consumption of the server hard disk, allocates reasonable power consumption for each hard disk, improves the power utilization rate, and reduces the power cost.
Fig. 1 is a schematic flow chart of a dynamic power consumption balancing method for a server hard disk according to this embodiment, which includes the following steps.
S101, acquiring a hard disk power consumption level list.
The hard disk power consumption level list comprises power consumption levels which can be supported by the hard disk and a power consumption limit value corresponding to each power consumption level.
It should be noted that one hard disk can support multiple power consumption levels, and each power consumption level corresponds to one power consumption limit value. That is, under a certain power consumption level, the power consumption extreme value of the hard disk does not exceed the power consumption limit value corresponding to the power consumption level.
For example, a hard disk has 1 level, 2 level, 3 level and 4 level for 4 power consumption levels, the power consumption limit value of the 1 level power consumption level is 10W, the power consumption limit value of the 2 level power consumption level is 11W, the power consumption limit value of the 3 level power consumption level is 12W, and the power consumption limit value of the 4 level power consumption level is 13W. When the hard disk works in a 2-level power consumption level, the power consumption extreme value of the hard disk does not exceed 11W.
And S102, regularly collecting the power consumption value of the hard disk.
The power consumption value of the hard disk is changed according to the service state of the hard disk, and when the hard disk is accessed infrequently, the power consumption level of the hard disk is reduced, so that the power consumption waste is avoided.
S103, determining the power consumption interval of the acquired hard disk power consumption value based on each power consumption limit value in the hard disk power consumption grade list.
The power consumption interval is an interval determined by two power consumption limit values, and the acquired power consumption value of the hard disk is located in the interval of the two power consumption limit values.
For example, the collected power consumption value of the hard disk is 10.5W, which is between 10W and 11W, i.e. the power consumption interval is (10W, 11W).
And S104, recording the power consumption limit value corresponding to the maximum endpoint value of the power consumption interval as a first target power consumption limit value, and determining the power consumption grade corresponding to the first target power consumption limit value as a first adjustment target power consumption grade of the hard disk.
And determining the first adjustment target power consumption level of the hard disk, namely adjusting the power consumption level of the hard disk to the first adjustment target level.
For example, the current power consumption level of a certain hard disk is 3 levels, the power consumption limit value of the 3-level power consumption level is 12W, the actual power consumption of the hard disk is 10.5W, and in the (10W, 11W) power consumption interval, the power consumption level corresponding to 11W is 2 levels, so that the power consumption level of the hard disk can be adjusted to 2 levels, and the power consumption of the hard disk is saved.
Compared with the prior art, the dynamic power consumption balancing method, the dynamic power consumption balancing device, the dynamic power consumption balancing terminal and the dynamic power consumption balancing storage medium for the server hard disk have the following beneficial effects: the power consumption values of the hard disks are collected regularly, and the power consumption level of each hard disk is reasonably adjusted according to the real-time power consumption value of the hard disk, so that the power consumption distribution of each hard disk is more reasonable, the power consumption utilization rate is effectively improved, unnecessary power consumption loss is avoided, and the power cost is reduced. And from the perspective of the server, the total power consumption of the hard disk is quantized and controlled, the normal operation of the service is ensured, and the purpose of hard disk power consumption management is achieved.
In some embodiments, the acquisition is performed by setting an acquisition period, and averaging over a period of time to improve the effectiveness of the adjustment.
The method specifically comprises the following steps of periodically acquiring the power consumption value of the hard disk:
step one, setting acquisition periods, wherein the monitoring time of each acquisition period is t seconds;
step two, within the monitoring time t seconds of the acquisition cycle, taking a power consumption instantaneous value of the hard disk every second;
and thirdly, averaging all the instantaneous values of the power consumption of the hard disk within t seconds to obtain an average value of the power consumption of the hard disk.
Correspondingly, in step S103, the power consumption interval of the collected power consumption value of the hard disk is determined based on each power consumption limit value in the power consumption level list of the hard disk, specifically:
and determining the power consumption interval of the acquired hard disk power consumption average value based on each power consumption limit value in the hard disk power consumption grade list.
Considering that server services are sometimes frequent and sometimes infrequent, the acquisition period may be adjusted according to the change frequency of the server services, and specifically the following steps are performed:
monitoring the service change frequency of a server in real time;
step two, if the service change frequency exceeds a first frequency threshold, shortening the acquisition period;
and step three, if the service change frequency is lower than a second frequency threshold, prolonging the acquisition period.
Wherein the first frequency threshold is greater than the second frequency threshold. It should be noted that the degree of shortening and lengthening can be determined according to specific requirements.
Example two
After the hard disk is set to a certain power consumption level, the power consumption extreme value of the hard disk is limited to the power consumption limit value of the power consumption level, however, in the operation process, the hard disk may continuously perform IO reading and writing, the power consumption of the hard disk is large, the actual power consumption of the hard disk is continuously close to the power consumption limit value, and at this time, it can be judged that the power consumption setting of the hard disk is too low, and the power consumption level of the hard disk needs to be increased.
Fig. 2 is a schematic flow chart of a dynamic power consumption balancing method for a server hard disk according to this embodiment, which includes the following steps.
S201, acquiring a hard disk power consumption level list.
The hard disk power consumption level list comprises power consumption levels which can be supported by the hard disk and a power consumption limit value corresponding to each power consumption level.
And S202, regularly collecting the power consumption value of the hard disk.
S203, determining the power consumption interval of the acquired hard disk power consumption value based on each power consumption limit value in the hard disk power consumption grade list.
And S204, recording the power consumption limit value corresponding to the maximum endpoint value of the power consumption interval as a first target power consumption limit value, and determining the power consumption grade corresponding to the first target power consumption limit value as a first adjustment target power consumption grade of the hard disk.
S205, calculating a difference value between the first target power consumption limit value and the average value of the power consumption of the hard disk, and recording as a continuous connection proximity value.
The continuous approach degree value represents the solution degree of the hard disk power consumption average value and the first target power consumption limit value, and the smaller the difference value is, the closer the difference value is.
S206, judging whether the continuous connection proximity value is less than or equal to a preset proximity threshold value.
A proximity threshold is preset to indicate whether the determined first target power consumption limit has not been met.
It will be appreciated that the first target power consumption limit that does not meet the requirements is typically the power consumption limit corresponding to the currently set power consumption level.
And S207, if yes, determining a higher power consumption grade of the first adjustment target power consumption grade as a second adjustment target power consumption grade of the hard disk.
S208, if not, the first adjustment target power consumption level is used as a second adjustment target power consumption level of the hard disk.
For example, the average value of the power consumption of the collected hard disk is 10.99W, the power consumption interval is (10W, 11W), and the 2-level power consumption level corresponding to 11W is determined as the first adjustment target power consumption level. If the preset proximity threshold is 0.02W, then 11-10.99W is 0.01W <0.02W, which indicates that the first adjustment target power consumption level (generally, the power consumption level set for the current hard disk) cannot meet the requirement, and at this time, a higher power consumption level of the 2-level power consumption level, that is, a 3-level power consumption level (the power consumption limit is 12W) should be used as the second adjustment target power consumption level of the hard disk, that is, the power consumption level of the hard disk can be adjusted to the 3-level power consumption level, so as to influence the IO read-write speed of the hard disk. And if the average value of the collected power consumption of the hard disk is 10.95W, and the power consumption of the hard disk is 11-10.95W which is 0.05W and more than 0.02W, taking the first adjustment target power consumption level (2-level power consumption level) as the second adjustment target power consumption level of the hard disk, namely, continuously adjusting the power consumption level of the hard disk to be 2-level power consumption level.
EXAMPLE III
On the basis of the second embodiment, considering that the rated power consumption allocated to the server hard disk is certain, when all the hard disks determine the second adjustment target power consumption level, the power consumption levels of some hard disks are adjusted to be higher, and at this time, the power consumption limit values of all the hard disks may exceed the rated power consumption of the server hard disk. Therefore, in order to avoid exceeding the rated power consumption of the server hard disk, for the hard disk with the adjusted power consumption level, whether to adjust the power consumption level finally is determined according to the magnitude of the continuous proximity value, namely the continuous proximity degree between the actual power consumption of the hard disk and the first target power consumption limit value. The greater the continuous proximity, i.e. the smaller the value of the continuous proximity, the more the power consumption level should be guaranteed to be increased, otherwise the power consumption level is not adjusted.
Fig. 3 is a schematic flow chart of a dynamic power consumption balancing method for a server hard disk according to this embodiment, which includes the following steps.
S301, acquiring a hard disk power consumption level list.
The hard disk power consumption level list comprises power consumption levels which can be supported by the hard disk and a power consumption limit value corresponding to each power consumption level.
And S302, periodically collecting the power consumption value of the hard disk.
S303, determining the power consumption interval of the acquired hard disk power consumption value based on each power consumption limit value in the hard disk power consumption grade list.
S304, recording the power consumption limit value corresponding to the maximum endpoint value of the power consumption interval as a first target power consumption limit value, and determining the power consumption grade corresponding to the first target power consumption limit value as a first adjustment target power consumption grade of the hard disk.
S305, calculating a difference value between the first target power consumption limit value and the average value of the power consumption of the hard disk, and recording as a continuous connection proximity value.
The continuous approach degree value represents the solution degree of the hard disk power consumption average value and the first target power consumption limit value, and the smaller the difference value is, the closer the difference value is.
S306, judging whether the continuous connection proximity value is less than or equal to a preset proximity threshold value.
And S307, if yes, determining the higher power consumption grade of the first adjustment target power consumption grade as a second adjustment target power consumption grade of the hard disk.
S308, if not, the first adjustment target power consumption level is used as a second adjustment target power consumption level of the hard disk.
S309, adding second target power consumption limit values corresponding to second adjustment target power consumption levels of all hard disks.
And S310, judging whether the sum of all the second target power consumption limit values exceeds the rated power consumption of the server hard disk.
And S311, if the power consumption level does not exceed the preset power consumption level, taking the second adjustment target power consumption level of each hard disk as the final adjustment target power consumption level of each hard disk.
Namely, the sum of the power consumption limit values of all the hard disks after adjustment does not exceed the rated power consumption of the server hard disk, and the power consumption requirement can be met.
And S312, if the power consumption value exceeds the preset value, recording the hard disks of which the second adjustment target power consumption level is one level higher than the first adjustment target power consumption level as preset hard disks, and sequencing the continuous approaching degree values of all the preset hard disks from large to small.
All hard disks with the continuous approaching degree values smaller than the preset approaching degree threshold value are recorded as preset hard disks, and then whether the hard disks need to be improved by one-level power consumption level is determined again.
S313, according to the continuous approach degree value from large to small, selecting n preset hard disks for the nth time, taking the first adjustment target power consumption level of the n preset hard disks as a second adjustment target power consumption level corresponding to the preset hard disks, judging whether the sum of all the second target power consumption limit values exceeds the rated power consumption of the server hard disk again (namely, returning to the step S309) until the sum of all the second target power consumption limit values does not exceed the rated power consumption of the server hard disk, and taking the second adjustment target power consumption level of each hard disk at the moment as the final adjustment target power consumption level of each hard disk.
Specifically, after step S312, the following steps are specifically performed:
step one, taking a first regulation target power consumption grade of a preset hard disk with the maximum continuous approach degree value as a second regulation target power consumption grade of the hard disk, and then calculating whether the sum of all second target power consumption limit values exceeds the rated power consumption of the hard disk of the server or not.
Starting from the preset hard disk with the maximum continuous approach degree value, the power consumption level of the preset hard disk with the maximum continuous approach degree value is adjusted back to the first adjustment target power consumption level.
For example, the average power consumption of a certain hard disk is 10.99W, and the power consumption of the certain hard disk is adjusted from a level 2 power consumption level to a level 3 power consumption level according to a preset proximity threshold value of 0.02W, so that the hard disk is preset. However, the difference between the average power consumption value of the preset hard disk 10.99W and the first target power consumption limit value 11W, that is, the continuous proximity value of 0.01W is the maximum value in the preset hard disk, and the first regulated target power consumption level (level 2 power consumption level) of the preset hard disk is still used as the second regulated target power consumption level, that is, the final regulated target power consumption level.
And step two, if the power consumption level of each hard disk is not exceeded, taking the second adjustment target power consumption level of each hard disk at the moment as the final adjustment target power consumption level of each hard disk.
The preset power consumption grade of one preset hard disk is adjusted back to meet the rated power consumption requirement of the server hard disk.
And step three, if the power consumption levels exceed the preset power consumption levels, taking the first regulation target power consumption levels of the two preset hard disks with the maximum continuous approaching degree value and the second maximum continuous approaching degree value as second regulation target power consumption levels of the two hard disks, calculating whether the sum of all second target power consumption limits exceeds the rated power consumption of the server hard disk, and repeating the steps until the sum of all second target power consumption limits does not exceed the rated power consumption of the server hard disk, and taking the second regulation target power consumption level of each hard disk at the moment as the final regulation target power consumption level of each hard disk.
If the power consumption level of one preset hard disk is adjusted back and the requirement of the rated power consumption of the server hard disk is not met, the power consumption levels of the two previous preset hard disks are continuously adjusted back, and the like until the rated power consumption of the server hard disk is met.

Different from the third embodiment, after all the second adjustment target power consumption levels are determined according to the continuous proximity value, if the rated power consumption of the server hard disk does not meet the requirement, a certain number of preset hard disks are directly selected to adjust the preset power consumption levels from large to small according to the continuous proximity value, and the adjustment efficiency is improved.
Specifically, the following steps are performed after step S308:
SS309, adding second target power consumption limit values corresponding to second adjustment target power consumption levels of all hard disks;
the SS310 judges whether the sum of the second target power consumption limit values exceeds the rated power consumption of the server hard disk;
SS311, if not exceeding, the second adjustment target power consumption level of each hard disk is used as the final adjustment target power consumption level of each hard disk;
SS312, if the power consumption of the second adjustment target is higher than that of the first adjustment target, recording the hard disks with the power consumption level higher than that of the first adjustment target as preset hard disks, and sequencing the continuous approaching degree values of all the preset hard disks from large to small;
SS313, according to certain proportion, according to lasting close degree value from big to small getting some preconditioning hard disks, first regulation goal power consumption grade of taking out preconditioning hard disk as the second regulation goal power consumption grade of the hard disk;
and the SS314 takes the second adjustment target power consumption level of each hard disk at the moment as the final adjustment target power consumption level of each hard disk.
Namely, the continuous approach degree value of the preset hard disk is adjusted from large to small, and the power consumption level is adjusted back according to a certain number of preset hard disks taken out. The specific amount can be set according to specific conditions or requirements.

EXAMPLE five
In order to further understand the present invention, this embodiment provides a dynamic power consumption balancing method for a server hard disk, and further explains the principles of the present invention.
And (I) acquiring a power consumption grade list of the hard disk and rated power consumption distributed to the hard disk of the server.
1) The BMC (baseboard management controller) firstly acquires a power consumption level list power _ list of the hard disk, namely the power consumption limit level of each hard disk, and each level corresponds to the power consumption of the hard disk and has a certain limit value of rated _ power. The power _ list lists the power consumption levels supported by the hard disk, power _ state, and the upper limit of power consumption at each level, rated _ power. Power _ state is in one-to-one correspondence with rate _ power, i.e., the rated power consumption of power _ state0 is rate _ power0, the rated power consumption of power _ state1 is rate _ power1, and so on. The hard disk provides a communication interface for inquiring the power consumption level for the BMC.
2) And acquiring the rated power consumption totle _ power allocated to the hard disk by the server. The whole rated power consumption of the hard disk subsystem is the sum of the power consumption limits of all the hard disks, namely the total maximum power consumption borne when all the hard disks reach the power consumption maximum limit of the hard disks. The total power consumption is a reference point for balancing all the hard disks, and no matter how power consumption limit values are set for each hard disk, the power consumption limit values of all the hard disks are added to be ensured not to exceed the total _ power.
And secondly, the BMC periodically acquires IO (input/output) or power consumption data of each hard disk through a polling mechanism and calculates the average value of the power consumption.
1) And setting a period T for acquiring power consumption data. And in the time period with frequent service change, the sampling period is shortened, and in the time period with slow service change, the sampling period is increased.
2) The monitoring time t of each cycle is set. And averaging the hard disk power consumption obtained in the monitoring time, namely avg _ power. One power consumption value power is taken every second, t seconds are continuously taken, then
avg_power＝(power1+power2+power3+……)/t。
And (III) calculating and setting the power consumption level of the hard disk.
1) And sequencing the average power consumption of all the hard disks acquired for the first time from low to high, firstly setting the power consumption of the hard disks with low power consumption, and sequentially setting the hard disks with high power consumption.
2) And (3) calculating a reasonable interval of the hard disk: the avg _ power is compared with the rate _ power in the power consumption list to determine the power consumption interval of the avg _ power. The method comprises the following specific steps:
rated_poweri<avg_power<rated_powerj
then the rated _ powerjCorresponding power _ statejIs the power consumption level to be set.
3) Equalization processes that continue to approach power consumption limits.
For hard disk 0, assume that the occurrence of avg _ power is continuously close to the hard disk's rated _ powerjThe proximity can be defined by setting a certain power _ margin, e.g. if rated _ powerjWhen avg _ power ≦ power _ margin, consider avg _ power to be continuously close to the rated _ powerj(ii) a Further, for the situation that the average power consumption is close to the power consumption limit value, it can be considered that the hard disk is continuously subjected to IO read-write, the limit value setting is too low to hinder the improvement of the IO read-write speed, it can be judged that the power consumption level setting at the moment is too low and needs to be adjusted, a power consumption level can be increased at the moment, and the power consumption level is adjusted to be power _ statej+1. And sequentially performing class pushing to each hard disk, and setting the power consumption level of the hard disk continuously close to the power consumption limit value.
4) After all the hard disks sequentially determine the set power consumption levels, the sum of the power consumption limit values is required to be ensured not to be higher than the total _ power. The equalization processing of the continuous approaching power consumption limit value can be adjusted through further calculation, each hard disk continuously approaching the power consumption limit value is sorted according to the approaching degree, namely the smaller the speed _ power-avg _ power is, the higher the approaching degree is, the power consumption limit value is increased for the hard disk with the higher approaching degree, and the lower the approaching degree is, the adjustment is not performed. And finally, uniformly sending commands to adjust all the hard disks.
5) The communication interface to be provided by the hard disk provides the power _ state and the rate _ power which can be accessed to the hard disk by the communication interface accessed from the outside, and provides the corresponding relation between the power _ state and the rate _ power. The hard disk provides a communication interface for setting a power consumption level. The physical channel may be I2C.
6) The BMC takes the power _ state and the rate _ power of the hard disks of all the hard disks through the interface provided by the hard disks, takes the corresponding relation between the power _ state and the rate _ power, implements the balancing strategy according to the logic, and sets the power consumption level for each hard disk.
