Description

Energy-saving scheduling method and system for data center
Technical Field
The invention relates to the field of data centers, in particular to a data center energy-saving scheduling method and system for realizing cross-layer unified energy consumption optimization of a data center.
Background
With the rapid development of cloud computing technology, as a physical platform of cloud computing, data centers around the world have also been developed unprecedentedly. The rapidly increasing number of data centers also causes significant energy consumption overhead for operators. For example, the total amount of electrical energy consumed by data centers in the united states in 2014 has accounted for 1.8% of the total annual energy consumption throughout the united states, and this value has also remained increasing year by year. In order to reduce the consumption of electric energy in data, a series of energy-saving schemes are provided in academia and industry. Since the server system and the machine room air conditioning system occupy more than about 80% of the power consumption of the data center in total, most of the research is conducted on the two systems. However, there is a trade-off between the energy saving goals for the server system and the air conditioning system. For example, an energy saving scheme for a server system may aggregate IT load onto a few servers to shut down as many servers as possible for energy saving purposes. However, due to the super-linear functional relationship between the fan speed and the energy consumption of the air conditioning system, the energy saving scheme for the air conditioning system can share the IT load among all the servers as much as possible. Therefore, the purpose of saving the overall energy consumption of the data center cannot be achieved by saving the energy consumption of any system in a unilateral manner.
At present, energy-saving schemes for cross-layer unification of a data center server and an air conditioning system are generally divided into three categories. The first type is that a specific mathematical function relation exists between the two systems and the IT load, and a scheduling algorithm is designed on the assumption to carry out overall energy-saving optimization design. However, because of the complex interaction and feedback loops among various parameters affecting the energy consumption of the data center, modeling the energy consumption of the data center by using the traditional engineering formula method is very inaccurate, and therefore, the scheme has poor effect in practice. And the second method is that a temperature sensor is arranged on a server, and the parameters of the cooling system are set according to temperature data sent back by the sensor, and the method cannot predict the total energy consumption of the data center and is difficult to guide the optimization of an energy-saving scheduling algorithm. The last method is a method based on a numerical analysis model to simulate a thermodynamic distribution diagram of the data center, and the method has too high calculation cost and cannot accurately reflect the complexity of heat dissipation of the data center, so that the aim of minimizing the total energy consumption of the data center by performing real-time scheduling on IT loads and setting system parameters cannot be fulfilled.

Detailed Description
For a further understanding of the technical aspects of the present invention, reference will now be made in detail to the embodiments of the present invention with reference to the accompanying drawings.
In this embodiment, an energy-saving scheduling method for a data center is provided, where the data center at least includes one or more servers, a machine room air conditioning system, a task queue, and an external environment parameter monitoring system, and fig. 1 is a flowchart of the energy-saving scheduling method for a data center according to an embodiment of the present invention, where the flowchart includes the following steps:
step 101, acquiring resource utilization rates of all servers in a current data center, resource requirements of tasks to be scheduled in a task queue and current external environment parameters. As known to those skilled in the art, the resource mainly refers to a CPU, and may also include a memory, a network bandwidth, a hard disk, and an IO. Because the pressure and the temperature of the external environment have great influence on the energy consumption of the data center air conditioning system, the external environment parameters mainly comprise the pressure and the temperature;
step 102, according to the acquired server resource utilization rate and current environment parameters, according to a preset prediction model, predicting the corresponding data center total power consumption and the corresponding machine room air conditioner setting parameters after the task to be scheduled is deployed on any one server, wherein the prediction model is generated based on a machine learning method;
and 103, determining a data center energy-saving scheduling scheme meeting preset conditions according to the prediction result, and scheduling the total energy consumption of the data center according to the energy-saving scheduling scheme.
Through the steps, the problem of low overall energy-saving efficiency of the data center caused by optimizing only aiming at the energy consumption of a single layer of the data center in the related technology is solved through the energy consumption of the combined dispatching server system and the machine room air conditioning system, in addition, the problem that an energy-saving strategy is invalid due to the fact that task dispatching is carried out based on an inaccurate energy consumption model in the related technology and the problem that the task dispatching strategy based on CFD simulation cannot meet the real-time dispatching requirement of the data center due to too large computing overhead is solved through the adoption of a machine learning-based method, and the energy consumption saving effect of the data center is further improved.
The preset prediction model can be generated by adopting the following method: the resource utilization rate of all servers in the data center and historical or experimental data corresponding to external environment parameters are acquired at certain time intervals and used as input of a neural network, and a set of machine room air conditioner setting parameters meeting the cooling requirements of the servers and the historical or experimental data of the total power consumption of the data center are acquired as output training. The neural network has strong nonlinear processing capacity, is very suitable for processing complex nonlinear relations in the data center, and is short in time spent when the model trained by the neural network is used for prediction, so that the neural network is suitable for real-time online scheduling of the data center. As known to those skilled in the art, the room air conditioning parameters mainly include temperature and wind speed (wind speed determines the amount of air delivered). The setting of air conditioning parameters in a data center requires the condition of server cooling to be satisfied, for example, the american society of heating, cooling and air conditioning engineers (ASHRAE) set the condition of server intake air to 18-27 ℃ in 2008. Therefore, under the condition that the resource utilization rate of the server and the external environment parameters are kept unchanged, a series of air conditioner parameter settings which accord with the refrigeration condition of the server can be obtained by traversing the air conditioner setting parameters, and one group of air conditioner setting parameters corresponding to the data center with the minimum total power consumption can be selected to be used as the output of the neural network.
There is a trade-off between the energy saving goals for the server system and the energy saving goals for the air conditioning system. For example, an energy saving scheme for a server system may aggregate IT load onto a few servers to shut down as many servers as possible for energy saving purposes. However, due to the super-linear functional relationship between the fan speed and the energy consumption of the air conditioning system, the energy saving scheme for the air conditioning system can share the IT load among all the servers as much as possible. Therefore, the purpose of saving the overall energy consumption of the data center cannot be achieved by saving the energy consumption of any system in a unilateral manner. In order to save the energy consumption of the data center on the whole, the total power consumption of the data center comprises two parts, namely the total power consumption of a server system and the total power consumption of a machine room air conditioning system.
The data center energy-saving scheduling scheme meeting the preset conditions can be determined by traversing all servers capable of containing the tasks to be scheduled, selecting the servers meeting the preset conditions after the tasks are deployed, and marking the servers as the servers to be scheduled. The condition that the server can accommodate the task to be scheduled is that the remaining resources of the server are not less than the resource demand of the task to be scheduled. Supposing that N servers are provided, calculating the resource utilization rate of the server after a task to be scheduled is deployed in a server I (1< ═ I < ═ N), inputting the resource utilization rate of the server, the resource utilization rates of all other servers and the current external environment parameters into a preset prediction model, recording (or storing) the output of the model, and selecting the servers meeting the preset conditions in N outputs and marking as I; and then, predicting the corresponding total power consumption of the data center and the corresponding air conditioner setting parameters of the machine room after the task is deployed on the server to be scheduled according to a preset prediction model, and if the corresponding output of the task deployed on the server I is stored in the process of determining the server to be scheduled, directly calling and recording to obtain the corresponding total power consumption of the data center and the corresponding air conditioner setting parameters of the machine room.
Meeting the preset conditions comprises the following steps: minimizing the overall power consumption of the data center.
The scheduling of the total energy consumption of the data center according to the energy-saving scheme comprises three aspects: deploying the task to the determined server to be scheduled; as tasks in the data center dynamically arrive and leave along with time, when a new task is deployed, a phenomenon that the utilization rate of part of servers is reduced, even part of servers are in an idle state because all tasks carried by the servers are processed, is likely to occur, and at this time, the servers in the idle state waste a large amount of energy consumption, so that the working state of the servers per se needs to be adjusted to realize power consumption scheduling of a server system, for example, the servers in the idle state are switched to a low-power-consumption sleep mode (even turned off), and the working voltage and frequency of the servers with low utilization rate are reduced; and adjusting the parameter setting group of the air conditioning system of the machine room to realize power consumption scheduling of the air conditioning system of the machine room. Due to the changes in the server load level and the operating state, the air conditioning room system needs to be adjusted accordingly to meet the new server refrigeration demand, because if the server system refrigeration demand decreases, the air conditioning system needs to correspondingly decrease the cooling capacity to reduce the energy consumption of the data center, and if the server system refrigeration demand increases, the air conditioning system needs to correspondingly increase the cooling capacity to meet the server refrigeration demand.
Because there is a certain possibility that the parameter setting of the air conditioning system of the machine room predicted by the prediction model cannot meet the cooling requirement of the current server, it is necessary to detect whether the parameter setting of the current air conditioning parameter reaches the cooling requirement of the server after adjusting the parameter setting group of the air conditioning system of the machine room, and as known to those skilled in the art, whether the parameter setting of the current air conditioning parameter reaches the cooling requirement of the server can be judged by detecting whether the temperature of the top inlet of the cabinet meets the specification (for example, is between 18 and 27 ℃); if the temperature is not reached, the air conditioner parameters can be finely adjusted until the cooling requirement of the server is reached, for example, if the temperature is higher than 27 ℃, the temperature and the air speed of the air conditioner can be gradually increased until the temperature reaches the standard, which indicates that the cooling capacity of the air conditioner is insufficient at the moment; if the temperature is lower than 18 ℃, which indicates that the cooling capacity of the air conditioner is excessive, the temperature and the wind speed of the air conditioner can be gradually reduced until the temperature reaches the standard.

In recent years, data centers have been developed in a standardized and large-scale manner. A large number of standardized cabinets are arranged in a large cloud computing data center in order, and a plurality of standardized servers are arranged in the cabinets. Based on the related technology, the cabinets of the existing data center are generally arranged in a manner of separating cold channels from hot channels, namely, cold air is blown upwards from small holes on the floor between two rows of cabinets and is sucked by the cabinets for refrigeration of servers in the cabinets, and hot air is discharged from the rear of the cabinets and is sucked away from the top of a house by refrigeration equipment. The servers can only work safely when the temperature of the servers cannot exceed the temperature specified by the manufacturer, and therefore, the parameter setting of the air conditioner of the machine room must be capable of ensuring that the temperature of all the servers cannot be higher than the safety range of the servers. Due to the influence of factors such as airflow, load distribution, environment and the like, the temperature of cold air at the inlets of different servers in the data center is greatly different, so that a large amount of energy consumption of the data center is wasted. The factors influencing the energy consumption of the data center are many, the relation is complex and is difficult to accurately depict by using the numerical relation, the scale of the cloud computing data center is large generally, so that some energy-saving schemes cannot meet the real-time scheduling requirement due to too large computing overhead, and the factors hinder the improvement of the energy-saving effect of the data center.
In view of the above problems, the present embodiment provides a load scheduling method based on energy consumption perception, and the method can make the distribution of loads meet the energy saving target of a data center as much as possible, so as to reduce the overall energy consumption of the data center. The method comprises the following steps:
301, acquiring resource utilization rates of all servers in the current data center, resource requirements of tasks to be scheduled and current external environment parameters by a data center monitoring platform;
step 302, according to the acquired resource utilization rate of the server and the current environmental parameters, predicting the corresponding total power consumption of the data center and the corresponding setting parameters of the air conditioner of the machine room after the task to be scheduled is deployed in any one machine cabinet according to a preset machine cabinet prediction model, wherein the prediction model is generated based on a machine learning method, and the machine cabinet with the minimum total power consumption of the corresponding data center after deployment is selected as the machine cabinet to be scheduled;
step 303, acquiring resource utilization rates of all servers in the cabinet to be scheduled, and predicting the total power consumption of the corresponding cabinet after the task to be scheduled is deployed in any one server according to a preset server prediction model, wherein the prediction model is generated based on a machine learning method, and the server with the minimum total power consumption of the corresponding cabinet after deployment is selected as the server to be scheduled;
and step 304, deploying the task to be scheduled to a server to be scheduled.
The prediction models in the steps 302 and 303 are generated by a machine learning method, and because the neural network has strong processing capability on complex relations and is very suitable for the energy-saving problem of a data center, the neural network can be adopted for model training. As known to those skilled in the art, neural networks are divided into three parts: the input layer, the hidden layer and the output layer can be realized by software. The cabinet prediction model based on the neural network in step 302 may be generated by the following method: the method comprises the steps of obtaining the resource utilization rate of all cabinets in a data center and history or experimental data of external environment parameters (mainly temperature and pressure) as input of a neural network, obtaining the corresponding total power consumption of the data center and the history or experimental data of machine room air conditioner setting parameters meeting the cooling requirements of a server as output of the neural network for training, and setting certain sampling time for collecting the data. The neural network based server prediction model in step 302 may be generated by: and acquiring history or experimental data of resource utilization rates of all servers in a given cabinet as input of a neural network at certain sampling time intervals, and acquiring history or experimental data of corresponding cabinet power consumption as output of the neural network for training. The power consumption data can be actually measured by a power meter or collected by simulation software.
Under the condition that all cabinets in the machine room are uniform and homogeneous, the model trained in step 303 can be applied to all cabinets, so that a large amount of training workload can be saved compared with a method for constructing a data center by load deployment and directly predicting total power consumption by using a neural network. Obviously, the above embodiment is also applicable to the scenario that the cabinets in the machine room are not uniform and homogeneous. By the embodiment, load scheduling based on energy consumption can be realized, the method can solve the problem of low overall energy-saving efficiency of the data center caused by inaccurate energy consumption depiction in the prior energy-saving technology, in addition, input and output parameters of the neural network are greatly reduced by decoupling in the step 302 and the step 303, the time for calculating and outputting the input data through the trained neural network is also greatly reduced, and the method can be used for realizing real-time energy-saving load scheduling.
The above embodiments are only intended to illustrate the technical solution of the present invention and not to limit the same, and a person skilled in the art can modify the technical solution of the present invention or substitute the same without departing from the spirit and scope of the present invention, and the scope of the present invention should be determined by the claims.
