Description
Technical Field
The invention relates to the technical field of data center management, in particular to a data center PUE (physical unclonable element) calculation and analysis method and system under a double-carbon background.
Background
PUE, power Usage Effectiveness, i.e., electrical energy utilization efficiency, is an indicator of evaluating the energy efficiency of a data center, and is the ratio of all energy consumed by the data center to the energy consumed by IT loads. PUE = data center total power consumption/IT equipment power consumption, wherein the data center total power consumption includes the power consumption of the IT equipment power consumption and the power consumption of the system such as refrigeration, distribution, etc., and ITs value is greater than 1, and the closer 1 indicates that the less the non-IT equipment power consumption is, the better the energy efficiency level is.
The existing PUE calculation and analysis method can theoretically promote the reduction of the energy consumption of the infrastructure of the data center, but as the index can not provide information about the energy efficiency of the IT equipment, the evaluation result and the actual production efficiency of the data center have great deviation, which is also an important reason for the problem caused by the PUE, and the point to be improved is mainly as follows:
1. the existing PUE theory only considers the duty ratio of the energy consumption of IT equipment in the total energy consumption of a data center; after the data center for carrying out infrastructure upgrade operates for a period of time, the energy consumption of the IT equipment can be increased due to the aging of the IT equipment; thereby increasing the IT device power consumption duty cycle so that the PUE value will decrease. However, the reduction of the PUE value is not from optimization of energy consumption of the data center, and cannot measure the power utilization efficiency of the data center, and if the aging energy consumption is continuously increased, the energy consumption is greatly wasted, and the potential risk of operation of the data center is increased.
2. The existing PUE theory does not consider the efficiency relation between IT equipment energy consumption and the total energy consumption of a data center; when IT devices adopt computing optimization technologies such as virtualization, the number of IT devices and the energy consumption thereof can be greatly reduced due to the increase of the working efficiency of a single device, which is beneficial to a data center. However, since the total energy consumption of the data center is not simply linearly related to the energy consumption of the IT equipment, the total energy consumption is not reduced to the same extent, which causes the PUE value to be increased instead.
3. The calculation definition formula of the existing PUE theory does not introduce a time concept, and cannot provide a substantial energy-saving direction for a data center.
Therefore, it is necessary to provide a method and a system for calculating and analyzing PUE of a data center in a dual-carbon background to solve the above technical problems.

Detailed Description
The invention will be further described with reference to the drawings and embodiments.
As shown in fig. 1, in the data center PUE calculation and analysis method under a dual-carbon background provided by the embodiment, an optimized PUE model is constructed to calculate and adjust a PUE value, so as to obtain an optimized PUE value closer to the real situation of the data center; tracking the optimized PUE value and recording the PUE related historical data; performing optimization analysis according to the PUE related historical data to obtain an optimization improvement strategy; the method comprises the following specific steps: an optimized PUE calculation model construction step, an optimized PUE value tracking and recording step and an optimized PUE improvement analysis step.
As a still further solution, the optimizing PUE calculation model building step is for, in particular, the substeps comprising: constructing a data center aging correction function, constructing a data center efficiency correction function, integrating a PUE model construction and calculating a PUE model numerical value;
the data center aging correction function is constructed by: the aging correction function is used for evaluating the aging degree of the data center and constructing an aging correction function corresponding to the IT equipment; when specific calculation is carried out, the corresponding data center aging correction quantity is obtained by calculating the aging correction function of the IT equipment;
the data center efficiency correction function is constructed by: the method is used for evaluating the performance improvement of the optimization means on the data center and constructing a performance correction function corresponding to the IT equipment; when specific calculation is carried out, the corresponding IT equipment efficiency correction quantity is obtained by calculating the efficiency correction function of the IT equipment;
the PUE model correction function is integrated: integrating the aging correction function and the efficiency correction function into an original PUE calculation model to obtain an optimized PUE calculation model PUE + ;
The optimized PUE calculation model is calculated by numerical value: and (5) inputting specific values of each parameter of the optimized PUE calculation model to obtain an optimized PUE value.
It should be noted that: the existing PUE calculation method only considers the ratio of the IT equipment energy consumption to the total energy consumption of the data center, does not consider the efficiency relation between the IT equipment energy consumption and the total energy consumption of the data center, and does not introduce a time concept into the calculation definition type; therefore, optimization improvement is needed; the embodiment provides a data center PUE calculation and analysis method under a double-carbon background to solve the problem; respectively constructing corresponding aging correction quantity and efficiency correction quantity through data center aging correction function construction and data center efficiency correction function construction; the aging correction can correct nonsensical decline of the PUE value caused by aging of IT equipment, and the effectiveness correction can correct the problem of abnormally increased PUE value caused by calculation optimization; in addition, the embodiment also analyzes the PUE related historical data to obtain the instruction for effective IT equipment aging maintenance and area optimization.
As a further solution, the data center aging correction function construction specific steps include: setting energy consumption function acquisition conditions, acquiring an initial energy consumption function, acquiring a current energy consumption function and calculating an aging correction function;
the energy consumption function acquisition condition is set: setting unit sampling time t, setting sampling point number N and setting maximum working intensity W of data center max Setting a working strength gradient value delta W; wherein Δw=w max N; the working strength is defined as the ratio of the calculated amount of the data center in unit time, wherein the unit time is the unit sampling time t;
the initial energy consumption function is collected: under the energy consumption function acquisition condition, carrying out initial energy consumption test on the data center in the initial stage to obtain a plurality of initial energy consumption data sampling points; connecting all the initial energy consumption data sampling points to obtain an initial energy consumption curve; fitting the initial energy consumption curve to obtain an initial energy consumption function IDF;
the current energy consumption function is acquired: under the energy consumption function acquisition condition, carrying out current energy consumption test on the data center in the current stage to obtain a plurality of current energy consumption data sampling points; connecting all the current energy consumption data sampling points to obtain a current energy consumption curve; fitting the current energy consumption curve to obtain a current energy consumption function CDF;
the aging correction function is calculated: collecting an initial energy consumption function IDF and a current energy consumption function CDF, and calculating an aging correction function ADF; the aging correction function ADF is a difference function between the current energy consumption function CDF and the initial energy consumption function IDF.
It should be noted that: because the energy consumption of the IT equipment is increased due to the aging of the IT equipment, and the relationship of the increase is not simply linear, the initial energy consumption function needs to be acquired and then compared with the current energy consumption function, so that an aging correction function is obtained; the energy consumption increasing value brought by aging under different working strengths can be obtained through the aging correction function, and the influence of the energy consumption increasing value on the calculation of the PUE value can be corrected by taking the energy consumption increasing value as the aging correction quantity.
As shown in fig. 2, we can clearly see that, in standby, the initial energy consumption function IDF and the current energy consumption function CDF have standby initial values, but the energy consumption is not very different; however, as the working strength increases, the load on the equipment increases, and the energy consumption effect due to aging increases dramatically, so that it is necessary to remove the effect when calculating the PUE value.
As a still further solution, the initial energy consumption function is collected: setting the working strength of the data center as a control variable, and setting the working energy consumption of the data center as an observation variable; setting different data center working strength values W according to the working strength gradient value delta W i Obtaining a working strength point set W; collecting to obtain W i Corresponding data center initial working energy consumption value E0 i Obtaining an initial working energy consumption point set E0; wherein W is i =ΔW*i,i∈[1,2,3....N];W=[W 1 ,W 2 ,W 3 ....W N ];E0=[E0 1 ,E0 2 ,E0 3 ....E0 N ]The method comprises the steps of carrying out a first treatment on the surface of the Converting E0 and W from the point set into a corresponding curve E0 (W), and obtaining an initial energy consumption function IDF through fitting: f (F) IDF (W)=E0(W);
The current energy consumption function is acquired: setting the working strength of the data center as a control variable, and setting the working energy consumption of the data center as an observation variable; setting different data center working strength values W according to the working strength gradient value delta W i Obtaining a working strength point set W; collecting to obtain W i Corresponding data center current working energy consumption value E1 i Obtaining a current working energy consumption point set E1; wherein W is i =ΔW*i,i∈[1,2,3....N];W=[W 1 ,W 2 ,W 3 ....W N ];E1=[E1 1 ,E1 2 ,E1 3 ....E1 N ]The method comprises the steps of carrying out a first treatment on the surface of the Converting E1 and W from the point set into a corresponding curve E1 (W), and obtaining a current energy consumption function IDF through fitting: f (F) CDF (W)=E1(W);
The aging correction function is calculated: f (F) ADF (W)=F CDF (W)-F IDF (W)=E1(W)-E0(W)。
It should be noted that: since the function operation is required, the external conditions except the control variable and the observation variable are the same, and the energy consumption function acquisition conditions are unified.
As a further solution, the data center efficiency correction function construction specific steps include: setting efficiency function acquisition conditions: the method comprises the steps of original efficiency function collection, optimized efficiency function collection and efficiency correction function calculation;
the efficiency function acquisition condition is set: setting a reference computing force u, setting the number M of working energy consumption sampling points and setting a working energy consumption boundary value E max Setting a calculated amount gradient value delta d; wherein Δd=e max M; the working energy consumption is the electric energy consumed by completing the appointed calculation amount under the current calculation force, wherein the current calculation force is the reference calculation force u;
the original efficacy function is collected: under the condition of efficiency function acquisition, closing calculation optimization; performing original efficiency test on the data center in the same test stage to obtain a plurality of original efficiency sampling points; connecting the original efficiency sampling points to obtain an original efficiency curve; fitting the original efficiency curve to obtain an original efficiency function OEF;
the optimized efficiency function is collected: under the condition of collecting the efficiency function, starting calculation optimization; performing optimization efficiency test on the data center in the same test stage to obtain a plurality of optimization efficiency sampling points; connecting the optimized efficiency sampling points to obtain an optimized efficiency curve; fitting the optimized efficiency curve to obtain an optimized efficiency function MEF;
the efficiency correction function is calculated: collecting original efficiency function OEF and optimized efficiency function MEF, and calculating efficiency correction function CEF; the efficiency correction function CEF is a difference function between the optimized efficiency function MEF and the original efficiency function OEF.
It should be noted that: the construction method of the efficiency correction function is similar to that of the aging correction function, except that the variables are different, the acquisition conditions of the efficiency function are different, and the PUE value caused by correcting the efficiency deviation can be abnormally increased through the different conditions.
As shown in fig. 3, the original performance function and the optimized performance function have little difference in energy consumption when no calculation task is performed, but the two energy consumption is gradually separated with the increase of the calculation amount; at the boundary value E of energy consumption max When the calculation task limit of the calculation unit is reached, it is easy to see that the calculation amount after calculation optimization is much larger than that of non-optimization calculation, and the influence of the calculation amount is that the PUE value is increased when the PUE value is calculated, so that the influence needs to be eliminated.
As a still further solution, the raw efficacy function is collected: setting the calculated amount of the data center as a control variable, and setting the working energy consumption of the data center as an observation variable; setting different data center calculation amounts d according to the calculation amount gradient value delta d j Obtaining a workload point set d; acquiring reference computing power u to complete corresponding data center computing quantity d j Data center original working energy consumption value E of (2) j Obtaining an original working energy consumption point set E; wherein d j =Δd*j,i∈[1,2,3....M];d=[d 1 ,d 2 ,d 3 ....d m ];E=[E 1 ,E 2 ,E 3 ....E m ]The method comprises the steps of carrying out a first treatment on the surface of the E and d are converted into a corresponding curve E (d) from the point set, and an original efficacy function OEF is obtained through fitting: f (F) OEF (d)=E(d);
The optimized efficiency function is collected: setting the calculated amount of the data center as a control variable, and setting the working energy consumption of the data center as an observation variable; setting different data center calculation amounts d according to the calculation amount gradient value delta d j Obtaining a workload point set d; acquiring reference computing power u to complete corresponding data center computing quantity d j Is used for optimizing the working energy consumption value of a data centerObtaining an optimized working energy consumption point set E'; wherein d j =Δd*j,i∈[1,2,3....M];d=[d 1 ,d 2 ,d 3 ....d m ];Converting E 'and d from the point set into a corresponding curve E' (d), and obtaining an optimized efficiency function MEF through fitting: f (F) MEF (d)=E`(d);
The efficiency correction function is calculated: f (F) CEF (d)=F MEF (d)-F OEF (d)=E`(d)-E(d)。
As a further solution, the PUE model correction function is integrated to obtain an optimized PUE calculation model PUE + :
Wherein D, U and T respectively represent total calculation amount, total calculation force and total calculation time for PUE calculation statistics, D is the same as D units, U is the same as U units, and T is the same as T units; e (E) Tot Total energy consumption of the data center; e (E) IT For the total energy consumption of the IT equipment,a data center aging correction amount; />For the average working strength of the PUE calculation, < >>Is an IT device performance modifier.
It should be noted that: the calculation is based on the same units, and if the units are different, normalization processing is also required, and the obtained distortion may be different, but the result is the same.
