Detailed Description
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Example 1
The power consumption management of the server is particularly important, and particularly with the development of big data, a large number of hard disks are applied more frequently in a data center, and the power consumption of the hard disks can be regulated and controlled, so that the power consumption of the hard disks becomes more and more important.
The power consumption limitation in the operation and maintenance machine room is always certain, in order to avoid the overlarge power consumption peak value or save the cost, the power consumption limitation is often set for each server in the operation and maintenance of the server, the mature practice in the industry is to limit the power consumption of key components such as a CPU, a memory and the like, but the power consumption limitation of a hard disk is relatively lacking. The hard disk storage subsystem occupies larger and larger power consumption proportion in a server or storage, and how to limit the power consumption of the hard disk storage subsystem is a difficult problem in the industry.
The present application contemplates that the division of the storage hard disk is generally different on the server, as are the hard disks used to exchange data frequently, and the cold data used to store infrequent accesses, so are the rate requirements of IO processing for each hard disk. In the current power consumption limiting scheme, the power consumption limit value of each hard disk in the server is generally the same, the power consumption limit value of the hard disk is indiscriminately limited, the power consumption limit value of the frequently accessed hard disk cannot be improved, IO performance is insufficient, access rate is affected, the power consumption limit value of the hard disk which is not frequently accessed is far higher than the power consumption limit value required by the hard disk, and the power consumption imbalance condition of each hard disk occurs. Under the condition of certain rated power consumption, the normal operation of the service is not affected, 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 particularly important.
Therefore, the embodiment provides a dynamic balancing method for power consumption of a server hard disk, which dynamically balances and adjusts 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 balancing method for power consumption of a server hard disk according to the present 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 supportable by the hard disk and power consumption limit values corresponding to the power consumption levels.
It should be noted that one hard disk may support multiple power consumption levels, and each power consumption level corresponds to one power consumption limit. 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, 2, 3, and 4 power consumption levels, the power consumption limit of the 1 power consumption level is 10W, the power consumption limit of the 2 power consumption level is 11W, the power consumption limit of the 3 power consumption level is 12W, and the power consumption limit of the 4 power consumption level is 13W. When the hard disk operates at the level 2 power consumption level, the power consumption extreme value thereof must not exceed 11W.
S102, periodically 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 not accessed frequently, the power consumption level of the hard disk is reduced, so that the power consumption waste of the hard disk is avoided.
S103, determining a power consumption interval of the collected hard disk power consumption value based on each power consumption limit value in the hard disk power consumption level list.
The power consumption interval is an interval determined by two power consumption limits, and the acquired hard disk power consumption value is located in the two power consumption limit intervals.
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).
S104, the power consumption limit value corresponding to the maximum endpoint value of the power consumption interval is recorded as a first target power consumption limit value, and the power consumption level corresponding to the first target power consumption limit value is determined as a first regulation target power consumption level of the hard disk.
And determining the first regulation target power consumption level of the hard disk, and regulating the power consumption level of the hard disk to the first regulation 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, but 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 can be saved.
The method, the device, the terminal and the storage medium for dynamically balancing the power consumption of the server hard disk have the following beneficial effects compared with the prior art: 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 values of the hard disks, 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 controllable, the normal operation of the service is ensured, and the purpose of managing the power consumption of the hard disk is achieved.
In some embodiments, the collection is performed by setting a collection period, and an average value is taken in a certain time to improve the adjustment effectiveness.
The specific periodic acquisition of the hard disk power consumption value comprises the following steps:
step one, setting acquisition periods, wherein the monitoring time of each acquisition period is t seconds;
step two, taking a hard disk power consumption instantaneous value every second in the monitoring time t seconds of the acquisition period;
and thirdly, averaging all the instantaneous values of the hard disk power consumption within t seconds to obtain an average value of the hard disk power consumption.
Correspondingly, in step S103, a power consumption interval of the collected hard disk power consumption values is determined based on each power consumption limit value in the hard disk power consumption level list, which specifically includes:
and determining a power consumption interval of the collected average power consumption value of the hard disk based on each power consumption limit value in the hard disk power consumption level list.
Considering that server traffic is sometimes frequent and sometimes infrequent, the acquisition period may be adjusted according to the frequency of variation of the server traffic, in particular the following steps are performed:
step one, 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 the second frequency threshold value, the acquisition period is prolonged.
Wherein the first frequency threshold is greater than the second frequency threshold. It should be noted that the extent of shortening and lengthening may be determined according to specific requirements.
Example two
When 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 read-write, the hard disk power consumption is larger, the actual power consumption of the hard disk continuously approaches to the power consumption limit value, at the moment, it can be judged that the power consumption of the hard disk is set too low, and the power consumption level of the hard disk needs to be adjusted.
Fig. 2 is a schematic flow chart of a dynamic balancing method for power consumption of a server hard disk according to the present embodiment, which includes the following steps.
S201, obtaining a hard disk power consumption level list.
The hard disk power consumption level list comprises power consumption levels supportable by the hard disk and power consumption limit values corresponding to the power consumption levels.
S202, periodically collecting the power consumption value of the hard disk.
S203, determining a power consumption interval of the collected hard disk power consumption value based on each power consumption limit value in the hard disk power consumption level list.
S204, the power consumption limit value corresponding to the maximum endpoint value of the power consumption interval is recorded as a first target power consumption limit value, and the power consumption level corresponding to the first target power consumption limit value is determined as a first regulation target power consumption level of the hard disk.
S205, calculating a difference value between the first target power consumption limit value and the hard disk power consumption average value, and recording the difference value as a continuous proximity value.
The continuous approach value represents the resolution of the average value of the hard disk power consumption 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 proximity value is smaller than or equal to a preset proximity threshold.
A proximity threshold is preset to characterize whether the determined first target power consumption limit has not met the requirement.
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.
S207, if yes, determining the power consumption level higher than the first regulation target power consumption level as a second regulation target power consumption level of the hard disk.
S208, otherwise, taking the first adjustment target power consumption level as a second adjustment target power consumption level of the hard disk.
For example, the average value of the collected power consumption of the hard disk is 10.99W, the power consumption interval is (10W, 11W), and the 2-level power consumption level corresponding to 11W is determined to be the first adjustment target power consumption level. The preset proximity threshold is set to be 0.02W, 11-10.99=0.01w <0.02W, which indicates that the first adjustment target power consumption level (generally the power consumption level set by the current hard disk) cannot meet the requirement, and at this time, the higher one of the 2-level power consumption levels, namely the 3-level power consumption level (the power consumption limit value is 12W) is used as the second adjustment target power consumption level of the hard disk, so that the power consumption level of the hard disk can be adjusted to be the 3-level power consumption level, so as to influence the IO read-write rate of the hard disk. If the average value of the collected power consumption of the hard disk is 10.95w, 11-10.95=0.05 w >0.02w, the first adjustment target power consumption level (2-level power consumption level) is used as the second adjustment target power consumption level of the hard disk, namely, the power consumption level of the hard disk is continuously adjusted 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 hard disk of the server is constant, after all the hard disks determine the second adjustment target power consumption level, the power consumption level of some hard disks is adjusted to be higher, and then the power consumption limit value of all the hard disks may exceed the rated power consumption of the hard disk of the server. Therefore, in order to avoid exceeding the rated power consumption of the hard disk of the server, for the hard disk with the power consumption level up, the present embodiment determines whether to eventually increase the power consumption level according to the magnitude of the continuous proximity value, that is, the continuous proximity between the actual power consumption of the hard disk and the first target power consumption limit value. The larger the continuous proximity, i.e. the smaller the continuous proximity value, 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 balancing method for power consumption of a server hard disk according to the present 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 supportable by the hard disk and power consumption limit values corresponding to the power consumption levels.
S302, periodically collecting the power consumption value of the hard disk.
S303, determining a power consumption interval of the collected hard disk power consumption value based on each power consumption limit value in the hard disk power consumption level list.
S304, the power consumption limit value corresponding to the maximum endpoint value of the power consumption interval is recorded as a first target power consumption limit value, and the power consumption level corresponding to the first target power consumption limit value is determined as a first regulation target power consumption level 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 the difference value as a continuous proximity value.
The continuous approach value represents the resolution of the average value of the hard disk power consumption 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 proximity value is smaller than or equal to a preset proximity threshold.
S307, if yes, determining the higher power consumption level of the first regulation target power consumption level as the second regulation target power consumption level of the hard disk.
And S308, otherwise, taking the first regulation target power consumption level as a second regulation target power consumption level of the hard disk.
S309, adding second target power consumption limit values corresponding to the second adjustment target power consumption levels of all the hard disks.
And S310, judging whether the sum of all the second target power consumption limits exceeds the rated power consumption of the hard disk of the server.
And S311, if the power consumption level does not exceed the second power consumption level, 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.
The sum of the power consumption limit values of all the hard disks after the adjustment does not exceed the rated power consumption of the hard disk of the server, and the power consumption requirement can be met.
And S312, if the power consumption level exceeds the first power consumption level, recording the hard disk with the second power consumption level higher than the first power consumption level as a preset hard disk, and sequencing the continuous proximity values of all the preset hard disks from large to small.
All hard disks with the continuous proximity value smaller than the preset proximity threshold value are recorded as preset hard disks, and whether the hard disks need to be increased in one-stage power consumption level is determined again.
S313, according to the continuous approach degree value from large to small, n preset hard disks are selected for n times, the first adjustment target power consumption level of the n preset hard disks is used as a second adjustment target power consumption level corresponding to the preset hard disk, whether the sum of all second target power consumption limit values exceeds the rated power consumption of the server hard disk is judged again (namely, the step S309 is returned) until the sum of all second target power consumption limit values does not exceed the rated power consumption of the server hard disk, and the second adjustment target power consumption level of each hard disk at the moment is used as the final adjustment target power consumption level of each hard disk.
Specifically, the following steps are specifically performed after step S312:
step one, taking a first regulation target power consumption level of a preset hard disk with the maximum continuous proximity value as a second regulation target power consumption level 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.
And starting from the preset hard disk with the maximum continuous approach degree value, and adjusting the preset hard disk power consumption level with the maximum continuous approach degree value back to the first adjustment target power consumption level.
For example, the average power consumption of a hard disk is 10.99W, and the hard disk should be adjusted from a level 2 power consumption level to a level 3 power consumption level to be a preset hard disk according to a preset proximity threshold value of 0.02W. However, if the difference between the average power consumption value of the preset hard disk and the first target power consumption limit value 11W, that is, the continuous approach degree value is 0.01W, is the largest in the preset hard disk, the first adjustment target power consumption level (2-level power consumption level) of the preset hard disk is still used as the second adjustment target power consumption level, that is, the final adjustment target power consumption level.
And step two, if the power consumption level does not exceed the first power consumption level, 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.
The rated power consumption requirement of the server hard disk is met after the preset power consumption level of one preset hard disk is adjusted back.
And thirdly, if so, taking the first regulation target power consumption level of the two preset hard disks with the maximum continuous proximity value and the second maximum continuous proximity value as the second regulation target power consumption level of the two hard disks, calculating whether the sum of all second target power consumption limit values exceeds the rated power consumption of the hard disk of the server, and the like until the sum of all second target power consumption limit values does not exceed the rated power consumption of the hard disk of the server, 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 still not satisfied after the power consumption level of the preset hard disk is adjusted back, the power consumption levels of the first two preset hard disks are continuously adjusted back, and the like until the rated power consumption of the server hard disk is satisfied.
Example IV
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 be adjusted back to the preset power consumption levels according to the continuous proximity value from large to small, so that the adjustment efficiency is improved.
Specifically, the following steps are performed after step S308:
SS309, adding the second target power consumption limits corresponding to the second adjustment target power consumption levels of all the hard disks;
SS310, determining whether the sum of all the second target power consumption limits exceeds the rated power consumption of the server hard disk;
SS311, if not exceeded, the second adjusted target power consumption level of each hard disk as the final adjusted target power consumption level of each hard disk;
SS312, if yes, recording the hard disk with the second adjustment target power consumption level higher than the first adjustment target power consumption level as a preset hard disk, and sorting the continuous proximity values of all preset hard disks from big to small;
SS313, taking a certain number of preset hard disks from large to small according to the continuous proximity value according to a certain proportion, and taking the first adjustment target power consumption level of the taken preset hard disk as the second adjustment target power consumption level of the hard disk;
and SS314, 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 continuous approach degree value of the preset hard disks is from large to small, and the power consumption level is adjusted back according to the preset hard disks taken out by a certain amount. The specific number may be set according to the specific situation or requirements.
Considering the limitation of rated power consumption of the hard disk of the server, after the final adjustment target power consumption level of all the hard disks is determined, the power consumption level adjustment is uniformly carried out on all the hard disks.
Example five
In order to further understand the present invention, this embodiment provides a dynamic balancing method for power consumption of a server hard disk, which further explains the principles of the present invention.
And (one) acquiring a power consumption level list of the hard disk and rated power consumption allocated to the hard disk of the server.
1) The BMC (baseboard management controller) first obtains a power consumption level list of the hard disk, i.e. each hard disk power consumption limit level, where each level corresponds to a hard disk power consumption with a certain limit value rate_power. Power_list lists the power level power_state supported by the hard disk and the upper limit rate_power of power consumption at each level. The power_state and the rated_power are in one-to-one correspondence, i.e., the rated power consumption of the power_state0 is rated_power0, the rated power consumption of the power_state1 is rated_power1, and so on. The hard disk provides a communication interface for the BMC to query the power consumption level.
2) The rated power consumption tolle_power allocated to the hard disk by the server is obtained. The overall rated power consumption of the disc subsystem is the sum of the power consumption limits of all the hard discs, i.e. the overall maximum power consumption carried by assuming that all the hard discs reach their own power consumption maximum limit at the same time. The sum of the power consumption is a reference point for balancing all the hard disks, and no matter how the power consumption limit value of each hard disk is set, the power consumption limit value of all the hard disks is ensured to be added up to not exceed total_power.
And secondly, through a polling mechanism, the BMC periodically collects IO or power consumption data of each hard disk and calculates the average value of power consumption.
1) Setting a period T of power consumption data acquisition. The sampling period is shortened in the time period with frequent service change, and the sampling period is increased in the time period with slow service change.
2) The monitoring time t for each cycle is set. And taking an average avg_power of the hard disk power consumption obtained in the monitoring time. Taking one power consumption value per second, continuously taking t seconds, then
avg_power＝(power1+power2+power3+……)/t。
And (III) calculating and setting the power consumption level of the hard disk.
1) The average power consumption of all the hard disks acquired for the first time is sequenced from low to high, the power consumption of the hard disks with low power consumption is set firstly, and the hard disks with high power consumption are set in sequence.
2) Calculating a reasonable interval of a hard disk: avg_power is compared with the rated_power in the power consumption list to determine the power consumption interval of avg_power. The method comprises the following steps:
rated_power i <avg_power<rated_power j
then rate_power j Corresponding power_state j The power consumption level to be set.
3) The equalization process is continued close to the power consumption limit.
For hard disk 0, it is assumed that avg_power is continuously approaching the hard disk rated_power j The proximity can be defined by setting a certain power_margin, e.g. if rate_power j When avg_power is less than or equal to power_margin, avg_power is considered to be continuously close to rate_power j The method comprises the steps of carrying out a first treatment on the surface of the Further, for the case that the average power consumption continuously appears and approaches the power consumption limit value, the hard disk is considered to be continuously read/written by IO, the limit value is too low to prevent the improvement of the IO read/write rate, the power consumption level at the moment can be judged to be too low to be adjusted, at the moment, one power consumption level can be increased, and the power consumption level is adjusted to be power_state j+1 . And analogizing to each hard disk, and setting the power consumption level of the hard disk which is continuously close to the power consumption limit value.
4) After all hard disks sequentially determine the set power consumption level, it is necessary to ensure that the sum of the power consumption limit values is not higher than total_power. The balance processing which is continuously approaching the power consumption limit value can be further calculated to be adjusted, each hard disk which is continuously approaching the power consumption limit value is ordered in the approaching degree, namely, the approach degree is higher as the rate_power-avg_power is smaller, the power consumption limit value of the hard disk with higher approach degree is improved, and the adjustment is not carried out when the approach degree is low. And finally, uniformly sending commands to regulate all the hard disks.
5) The communication interface to be provided by the hard disk provides a power_state and a rate_power which can be accessed to the hard disk by the communication interface accessed from outside, and provides a corresponding relation between the power_state and the rate_power. The hard disk provides a communication interface that sets the power consumption level. The physical channel may be I2C.
6) The BMC obtains the power_state and the rate_power of all the hard disks through interfaces provided by the hard disks, obtains the corresponding relation between the power_state and the rate_power, and sets the power consumption level for each hard disk according to the logic equalization strategy.
