Description

Technical Field

[0001] The present invention relates to the technical field of data center energy consumption control, and in particular to a method and device for controlling data center energy consumption based on a PUE value. Background Art

[0002] PUE (Power Usage Effectiveness) is an indicator used to evaluate the energy efficiency of data centers. According to TGG's definition, PUE is the ratio of the total energy consumption of all data center equipment to the energy consumption of electronic information equipment. Currently, PUE is mainly used to evaluate the energy efficiency of data center infrastructure. The closer the PUE value is to 1, the more green a data center is. According to the data center energy consumption model, assuming a data center PUE of 1.4, the energy consumption of electronic information equipment is 2.5 times that of infrastructure equipment. Energy-saving measures for electronic information equipment can significantly reduce data center energy consumption.

[0003] Therefore, the currently recognized PUE indicator can only evaluate the energy efficiency of the computer room infrastructure, and has certain guiding significance on the computer room infrastructure side. However, because it requires measuring a large amount of data, the large number of installed sensor devices cannot be further utilized to guide energy conservation work in the overall energy consumption of the data center.

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0037] It will be understood by those skilled in the art that embodiments of the present invention may be provided as methods, systems, or computer program products. Thus, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware. Furthermore, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to magnetic disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

[0038] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or apparatuses.

[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.

[0041] It should be noted that the method and device for controlling data center energy consumption based on PUE value of the present invention can be applied to the financial field as well as other technical fields.

[0042] To address the fact that PUE can only evaluate the energy efficiency of computer room infrastructure, this invention further utilizes the PUE indicator to identify the energy usage of electronic information equipment in data centers. This allows for energy efficiency evaluation related to the operation of electronic information equipment, and can also use the evaluation results to control the operation of electronic information equipment, thereby improving its effective energy use and further enhancing data center energy efficiency. This invention is applicable to cloud server architectures and similar architectures.

[0043] PUE: Power usage effectiveness, a parameter that characterizes the power utilization efficiency in a data center. Its value is the ratio of the total power consumed by all electrical equipment in the data center to the total power consumed by all electronic information equipment.

[0044] Local PUE (pPUE): pPUE is the total energy consumption within a certain boundary of the data center divided by the energy consumption of the IT equipment within that boundary.

[0045] Figure 1 FIG. 1 is a first flow chart of a method for controlling energy consumption of a data center based on a PUE value according to an embodiment of the present invention. Figure 1 As shown, in one embodiment of the present invention, the method for controlling energy consumption of a data center based on a PUE value includes step S101 and step S102.

[0046] Step S101 : determining the pPUE value corresponding to each computer room in the data center based on the energy consumption of electronic information equipment and the energy consumption of the cooling system in each computer room.

[0047] PUE is closely related to the cooling system, power supply and distribution system, and computer room load factor. Since the power supply and distribution architecture remains unchanged after data center construction, its impact on PUE remains largely unchanged. Therefore, changes in PUE after data center construction are primarily influenced by the cooling system and load factor. The cooling system's energy efficiency is closely related to outdoor meteorological parameters, and its impact on PUE fluctuates throughout the year. However, at any given moment, outdoor meteorological parameters for each computer room are consistent, so PUE is closely related to load factor. Load factor, in turn, is related to business conditions. Typically, high load factors during peak business hours indicate good energy efficiency, while low load factors during low business hours indicate poor energy efficiency.

[0048] In the present invention, pPUE refers to local PUE, and each computer room in a data center corresponds to a local PUE. Electronic information equipment (ie, IT equipment) may be a server, etc.

[0049] In the present invention, the local PUE (i.e., pPUE value) of a computer room is specifically the ratio of the energy consumption of the electronic information equipment in the computer room to the total energy consumption of the computer room. In the present invention, the total energy consumption of the computer room is approximately regarded as the sum of the energy consumption of the electronic information equipment and the energy consumption of the cooling system.

[0050] In the present invention, energy consumption may refer to electricity consumption.

[0051] Step S102: Taking the minimum value of the pPUE values corresponding to each of the computer rooms as the target pPUE value, adjusting the tasks processed by the electronic information equipment in the first target computer room, and / or adjusting the cooling capacity output of the refrigeration system in the first target computer room, so that the adjusted pPUE value of the first target computer room reaches the target pPUE value range, wherein the target pPUE value range is determined based on the target pPUE value, and the first target computer room is a computer room in the data center whose pPUE value is greater than the target pPUE value and less than or equal to a preset value.

[0052] In the present invention, the data center typically (or can) monitor the total energy consumption of electronic information equipment and the energy consumption of the cooling system serving each computer room. Based on the monitored data, the local PUE (Purpose Use Effectiveness) of the computer room, or pPUE, can be calculated to obtain the energy efficiency of each computer room. The pPUE values of all computer rooms are then compared and analyzed to obtain the optimal pPUE value, i.e., the minimum pPUE value. With this optimal pPUE value as the target, computing tasks for all computer rooms are scheduled, concentrating computing in one or more computer rooms. The cooling systems of these computer rooms are also adjusted to meet heat dissipation requirements. For the remaining computer rooms, the number of operating cooling systems can be reduced as needed to match the heat dissipation and achieve the optimal pPUE value.

[0053] It can be seen that the present invention effectively improves the energy efficiency of each computer room, thereby improving the overall energy efficiency of the data center.

[0054] In one embodiment of the present invention, the method for controlling data center energy consumption based on the PUE value of the present invention further includes:

[0055] The tasks processed by the electronic information equipment in the second target computer room are transferred to the electronic information equipment in the first target computer room for processing, and the electronic information equipment and the cooling system in the second target computer room are shut down or put on standby, wherein the second target computer room is a computer room in the data center whose pPUE value is greater than the preset value.

[0056] In the present invention, the present invention can find computer rooms with a large number of unloaded electronic information equipment based on pPUE value analysis, and then transfer the tasks processed by the electronic information equipment, shut down the electronic information equipment and cooling system in the computer room, so as to improve the overall energy efficiency of the data center.

[0057] like Figure 2 As shown, in one embodiment of the present invention, the above step of transferring the task processed by the electronic information equipment in the second target computer room to the electronic information equipment in the first target computer room for processing specifically includes step S201 and step S202.

[0058] Step S201 : selecting a third target computer room from all first target computer rooms according to the number of tasks processed by the electronic information equipment in each first target computer room.

[0059] Step S202: Allocate the electronic information equipment processing tasks in the second target computer room to the third target computer room, and adjust the cooling capacity output of the cooling system in the third target computer room so that the adjusted pPUE value of the third target computer room reaches the target pPUE value range.

[0060] In one embodiment of the present invention, the task of adjusting the processing of electronic information equipment in the first target computer room in step S102 specifically includes:

[0061] Part of the tasks processed by the electronic information equipment in the first target computer room is transferred to the electronic information equipment in another first target computer room for processing.

[0062] Figure 3 FIG3 is a third flow chart of a method for controlling energy consumption of a data center based on a PUE value according to an embodiment of the present invention. Figure 3 As shown, in one embodiment of the present invention, the specific process of the method for controlling data center energy consumption based on PUE value of the present invention is as follows:

[0063] Step 1: Obtain the server power consumption and total power consumption of each computer room, calculate the pPUE of each computer room, and sort the pPUE;

[0064] Step 2: Compare and obtain the minimum pPUE value, recorded as pPUEmin, and obtain the power consumption of the server equipment and the total power consumption of the pPUEmin computer room;

[0065] Step 3: Using pPUEmin as the target value, schedule the servers in each computer room in descending order of their pPUE values, so that the pPUE of the corresponding computer room approaches pPUEmin, with a control deviation of ±5%;

[0066] Step 4: Shut down or adjust the cooling output of the air conditioners in server rooms where the number of servers running is reduced or the power is reduced;

[0067] Step 5: The refrigeration system automatically adjusts its operation according to the change in cooling capacity.

[0068] The above steps 1 to 5 are repeated every preset time, and the preset time may be 30 minutes.

[0069] As can be seen from the above embodiments, the method of controlling data center energy consumption based on PUE value of the present invention achieves at least the following beneficial effects:

[0070] This method uses pPUE to analyze and schedule the operation of electronic information equipment while simultaneously modifying the refrigeration system's operation, obtaining the optimal PUE for each computer room and, in turn, the optimal PUE for the data center, thereby reducing data center energy efficiency. Furthermore, PUE can be used to analyze the operation of electronic information equipment and, through scheduling, concentrate computing tasks on certain electronic information equipment, increasing their power while freeing up other electronic information equipment and reducing overall energy consumption.

[0071] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
