Description

Electric energy reduction control device, electric energy reduction control method, electric energy reduction control system, and program

The present invention relates to a power consumption reduction control device, a power consumption reduction control method, a power consumption reduction control system, and a program that reduce power consumption in a data center (hereinafter sometimes referred to as "DC").

The power consumption of air conditioning in data centers (DCs) accounts for a large proportion, and as the number and scale of DCs increases, there is a need to reduce the power consumption of air conditioning. Furthermore, the amount of data processed in a DC tends to increase year by year, and it is necessary to improve the power consumption efficiency of the entire DC (the amount of power consumed by the entire DC for processing a certain amount of data).

A technique described in Non-Patent Document 1 has been disclosed as a technique for optimizing the overall power consumption of a DC by considering the power consumption of air conditioning and the power consumption of a server (IT device).
In the air conditioning linked IT load placement optimization method for data centers described in Non-Patent Document 1, by collecting operating information and monitoring information of IT equipment in the data center, it is possible to predict future changes in the loads of IT equipment and Calculate the power increase for air conditioning equipment according to the power increase. Then, an optimization problem is solved in which the objective function, which is the power amount of the data center, is minimized so that the load aggregation rate on IT equipment increases over time, that is, the number of operating IT equipment is reduced. This calculates the placement of IT loads (virtual machines) on IT equipment that minimizes the power consumption of the data center.

However, in the technology described in Non-Patent Document 1, a general-purpose rule-based standard that does not depend on equipment conditions that differ for each DC is adopted in the air conditioning power model used to calculate the power of the air conditioning equipment. Therefore, it was difficult to optimize the total amount of power consumed by the DC, taking into account individual equipment conditions such as the location of air conditioning equipment, airflow, server arrangement within the DC, and thermal cooling efficiency. .

Further, within the DC, it is assumed that load processing is performed in an environment in which a CPU (Central Processing Unit) server, a GPU (Graphics Processing Unit) server, and an accelerator coexist. Here, the accelerator is, for example, an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), or a TPU (Tensor Processing Unit).

The CPU, GPU, and accelerator differ in the amount of power consumption required for server cooling during load processing. Specifically, CPUs show almost no fluctuations in power consumption within the normal temperature range, whereas GPU servers and accelerators experience fluctuations in power consumption even within the normal temperature range. It is assumed that

The inventor of this application set the inlet temperature of the GPU server at 20 degrees Celsius and 33 degrees Celsius, which are within the normal temperature range, and set the temperature of the GPU card in the GPU server (GPU temperature), the amount of power consumption, and the fan rotation. The rate was measured.
As a result, the GPU temperature increases by approximately 10 degrees at 33 degrees Celsius when comparing the inlet temperature between 20 degrees Celsius and 33 degrees Celsius, as shown in FIG. Furthermore, as shown in FIG. 2, the power consumption of the GPU card also increases by approximately 20 W at 33 degrees Celsius. Furthermore, the fan rotation rate of the GPU server also increases by approximately 10% at 33° C., as shown in FIG. Note that the horizontal axis in FIGS. 1 to 3 represents time [minutes: seconds] from the start of measurement.

In the experiment, when the inlet temperature was 20 degrees Celsius, the power consumption of four GPU cards was "0.66 kWh", and the power consumption of the GPU server itself excluding the GPU cards was "0.33 kWh", and the power consumption of the GPU server as a whole was ``0.33 kWh''. , "0.99kWh". On the other hand, when the inlet temperature is 33°C, the power consumption of the four GPU cards is "0.72kWh", and the power consumption of the GPU server itself excluding the GPU card is "0.37kWh", and the power consumption of the GPU server as a whole is: It was "1.09kWh". From this result, it was confirmed that as the inlet temperature rose from 22° C. to 33° C., the power consumption of the entire GPU server increased by about 9%.

In other words, conventional research has not been able to perform modeling that takes into account differences in power consumption characteristics required for cooling functions with respect to inlet temperature in an environment where CPU servers, GPU servers, accelerators, etc. coexist. More specifically, when the air conditioning control stage is set to "strong", the inlet temperature becomes "low" and the server power consumption becomes "low" and decreases, but the air conditioning power consumption becomes "high". On the other hand, when the air conditioning control stage is set to "low", the inlet temperature becomes "high" and the server power consumption becomes "high" and increases, but the air conditioning power consumption can be set to "low". That is, there is a trade-off relationship between the level of air conditioning power consumption due to air conditioning control and the level of server power consumption. Therefore, it is difficult to accurately estimate the power consumption of the entire DC, which consists of server power consumption and air conditioning power consumption. It was not possible to reduce the amount of electricity.

The present invention was made in view of these points, and the present invention reduces the total power consumption consisting of server power consumption and air conditioning power consumption in an environment where CPU servers, GPU servers, accelerators, etc. coexist. The task is to do so.

This server group includes at least one CPU server 3, GPU server 4, and accelerator 5. In addition, when there is no GPU server 4 and the CPU server 3 and accelerator 5 are included, the accelerator 5 This also includes a case where there is no server and the server is configured with a CPU server 3 and a GPU server 4.
Note that the power amount reduction control device 100 may be provided inside the DC 10 or may be provided in a location different from the DC 10 and may control a plurality of DCs 10.

This power consumption reduction control device 100 receives status information of air conditioners 2 (air conditioners “1”, “2”, and “3” in FIG. 4) installed in the DC 10 via an air conditioning management device (not shown). The information may be acquired, the air conditioning control information may be transmitted, or the communication may be directly connected to each air conditioner 2 without using an air conditioning management device.
The power consumption reduction control device 100 also acquires status information and controls the CPU server 3, GPU server 4, and accelerator 5 that are accommodated as a server group provided in the DC 10 via a server management device (not shown). It may transmit information, or it may be directly communicatively connected to each CPU server 3, GPU server 4, and accelerator 5.

In the DC 10 in this embodiment, the CPU server 3, the GPU server 4, and the accelerator 5 are arranged as shown in FIG. Each area is divided and controlled as a "placement control area." This placement control area 30 is an area that accommodates a group of servers on which processing loads (virtual resources, processing of GPUs, accelerators, etc.) are placed. FIG. 4 shows an example in which placement control areas "1" to "6" are provided.

Note that in the DC 10, a virtualization infrastructure is constructed in the CPU server 3, and the description will be made assuming that it is operated using containers and VMs. Known open source virtualization platforms include OpenStack (registered trademark), which is software for building cloud environments, and Kubernetes (registered trademark), which is software for operating and managing containerized workloads and services. There is. OpenStack is primarily used for managing and operating physical machines and virtual machines (VMs). Kubernetes is mainly used for managing and operating containers.

In Kubernetes, the minimum execution unit of an application is a Pod, which is made up of one or more containers.

In this embodiment, an "air conditioning control area" is provided as shown in FIG. 4 in association with the placement control area 30 of the server group. The air conditioning control area 20 is a grouped area in which the room temperature effect due to air conditioning control is measured, and faces either the suction port side or the discharge port side of each server (CPU server 3, GPU server 4, accelerator 5). shall be taken as a thing.
The air blown from the air conditioner 2 is sent to the air conditioning control areas 20 (in FIG. 4, air conditioning control areas "3", "4", and "7") on the suction side via piping installed under the floor of the DC 10, for example. ”, “8”). Then, air whose temperature has risen due to the heat of each server flows from the suction ports of the piping provided in the air conditioning control area 20 on the discharge port side (air conditioning control areas "1", "2", "5", and "6" in FIG. 4). This generates an airflow that returns to the air conditioner 2.

A plurality of sensors (temperature sensors, etc.) are installed in each of the air conditioning control areas 20. Furthermore, temperature sensors are also installed at the suction ports of the GPU servers 4 and accelerators 5 in each placement control area 30. Furthermore, a sensor (temperature sensor, etc.) is installed outside the DC 10 as well. Information obtained from these sensors (sensor information) can be acquired by the power consumption reduction control device 100 via a communication line or the like.

The power consumption reduction control device 100 according to the present embodiment reduces the load to each server resource (this embodiment The amount of heat generated for each placement control area 30 ("predicted heat generation amount of placement control area" to be described later) in the placement pattern arranged in the CPU server 3, GPU server 4, and accelerator 5 is predicted. Note that the above "/" means "and/or". The power consumption reduction control device 100 sets air conditioning control values for the air conditioner 2 in multiple stages for each situation (“Situation” to be described later) of the external temperature of the DC 10, the floor temperature, and the predicted amount of heat generation in the placement control area 30. Temperature distribution information and air conditioning power consumption information when controlled at each stage are held. Then, the power consumption reduction control device 100 calculates the server power consumption (to be described later, "total server power consumption") of each placement control area 30 based on the temperature distribution information etc. when controlling at each stage, Determine the layout pattern that minimizes the total amount of server power consumption and air conditioning power consumption (details will be described later). The power amount reduction control device 100 will be described in detail below.

<Power consumption reduction control device>
FIG. 5 is a functional block diagram showing a configuration example of the power amount reduction control device 100 according to the present embodiment.
The power consumption reduction control device 100 predicts the amount of heat generated (predicted amount of heat generated) for each placement control area 30 in each load placement pattern of server resources (CPU server 3, GPU server 4, accelerator 5), and calculates the situation (Situation). ), temperature distribution information 64 and air conditioning power consumption information 65 are acquired when the air conditioning of the air conditioner 2 is controlled. Then, the power consumption reduction control device 100 calculates the server power consumption of each of the CPU server 3, GPU server 4, and accelerator 5 using the learning model, and adds up the power consumption of each of the CPU servers 3, GPU servers 4, and accelerators 5. 3. Calculate the total power consumption of the GPU server 4 and accelerator 5. The power consumption reduction control device 100 calculates the total server power consumption (total server power consumption to be described later), which is the sum of the total power consumption of the CPU server 3, GPU server 4, and accelerator 5 in each placement control area 30. , and the air-conditioning power consumption, determine an arrangement pattern that minimizes the total amount, and execute load arrangement and air-conditioning control based on the arrangement pattern.
This power consumption reduction control device 100 is constituted by a computer including a control section, an input/output section, and a storage section (all not shown).

The input unit inputs and outputs information between each device in the DC 10 (each air conditioner 2 and each server (CPU server 3, GPU server 4, accelerator 5)), etc. This input/output unit is composed of a communication interface that sends and receives information via a communication line, and an input/output interface that inputs and outputs information between an input device such as a keyboard (not shown) and an output device such as a monitor (not shown). be done.

The storage unit includes a hard disk, flash memory, RAM (Random Access Memory), and the like.
This storage section temporarily stores programs for executing each function of the control section and information necessary for processing of the control section. This storage unit also contains control values for the air conditioner 2 (air conditioning control value information 63) for each Situation in each arrangement pattern, temperature distribution information 64 as the control result, air conditioning power consumption information 65, etc. Operation history information 201 indicated by is stored. Furthermore, the storage unit includes basic power consumption information 301 for calculating the predicted heat generation amount of each server (CPU server 3, GPU server 4, accelerator 5), and CPU information 301 for predicting the power consumption of the CPU server 3. A server power amount learning model 302, a GPU server power amount learning model 303 for predicting the power consumption of the GPU server 4, and an accelerator power amount learning model 304 for predicting the power consumption of the accelerator 5 are stored. (Details below).

The control unit is in charge of overall processing executed by the power consumption reduction control device 100, and is configured to include an air conditioning control unit 200 and a server control unit 300, as shown in FIG.

≪Air conditioning control section≫
The air conditioning control unit 200 uses the average temperature of the floor in the DC 10 before control (floor average temperature), the outside temperature (outside air temperature), and the predicted amount of heat generation for each location control area 30 as Situation components, and performs each air conditioning control for each Situation. In the step (setting the air conditioning control value of each air conditioner 2 in stages), temperature distribution information 64 is acquired in the control turn, and air conditioning power consumption information 65 is calculated, thereby generating operation history information 201. The phase in which this operation history information 201 is generated is referred to as a learning phase. In addition, when the air conditioning control unit 200 acquires information on the predicted heat generation amount of each placement control area 30 from the server control unit 300 during the operation phase in which load placement and air conditioning control are actually executed, the air conditioning control unit 200 selects the corresponding Situation (Situation classification 62). , and outputs temperature distribution information 64 and air conditioning power consumption information 65 to the server control unit 300. Then, the air conditioning control unit 200 causes each air conditioner 2 to perform air conditioning control in the arrangement pattern determined by the server control unit 300.
The air conditioning control unit 200 includes a situation recognition unit 210, an operation history information generation unit 220, an operation history information extraction unit 230, and an air conditioning control execution unit 240.

The situation recognition unit 210 acquires information on external factors that are parameter elements that constitute the Situation. Then, the situation recognition unit 210 divides each external world factor into a plurality of ranges, defines a combination of each range area as one situation, and determines a situation classification 62 indicating which situation it belongs to based on the acquired information on the external world factor. .
The situation recognition section 210 includes an external world factor acquisition section 211 and a situation determination section 212.

The external world factor acquisition unit 211 acquires information on the measurement results of external world factors. Here, the external factor is an element that affects an increase or decrease in air conditioning power consumption, and means a parameter element that constitutes the Situation classification 62. Here, the external factors are (1) the average floor temperature in the DC 10 before control, (2) the outside temperature (outside air temperature), and (3) the predicted amount of heat generation for each placement control area 30.

(1) The external factor acquisition unit 211 calculates the floor average temperature in the DC 10 before control as follows. The external factor acquisition unit 211 calculates the average value of the temperatures acquired from the temperature sensors of the air conditioning control area 20, and calculates the average temperature for each air conditioning control area 20. Then, the external factor acquisition unit 211 averages the calculated average temperature for each air conditioning control area 20 over the entire floor, and sets the obtained temperature as the floor average temperature.

(2) The external temperature is information obtained from a temperature sensor installed outside the DC 10.
(3) The predicted amount of heat generation for each placement control area 30 is information calculated by the server control unit 300 (details will be described later).
When the external world factor acquisition unit 211 acquires information on this external world factor, it outputs it to the Situation determination unit 212 .

The Situation determining unit 212 determines to which Situation classification 62 the information acquired by the external world factor acquiring unit 211 belongs.
Each external factor is divided into a plurality of ranges between the minimum value and the maximum value depending on the characteristics of the external factor. Then, a combination of ranges obtained by dividing each external factor is defined as one Situation. This will be explained below with reference to FIG.

As shown in FIG. 6, each of the external factors is defined as a "factor", and a range for division is defined (hereinafter referred to as "division definition").
For example, the external factor of "factor 1" shown in the Situation classification 62 in FIG. 6 is "floor average temperature", and the division definition is "0-48 degrees divided into 6". The external factor of "factor 2" is "external temperature", and the division definition is "0-48 degrees divided into 6". The external factor of "factor 3" is "predicted amount of heat generation in placement control area 1", and the division definition is "0-200W divided into 20". Similarly, the external factor of "factor 8" is "predicted heat generation amount of placement control area 6", and the division definition is "0-200W divided into 20".

Here, it is assumed that the external world factor information acquired by the Situation determination unit 212 is the external world factor information 61 shown in FIG. In this case, the Situation determination unit 212 determines that since the value of "factor 1" (floor average temperature) is "25", the "range" is included in the "24-32 range" (24 degrees or more and less than 32 degrees), Set the "factor range identifier" to "factor1-4". This "factor range identifier" is, for example, 0-48 degrees divided into 6, "factor1-1" for 0 degrees or more and less than 8 degrees, "factor1-2" for 8 degrees or more and less than 16 degrees, and "factor 1-2" for 8 degrees or more and less than 16 degrees, and 16 degrees or more and less than 16 degrees. This is information that identifies the range to which it belongs, such as "factor1-3". The same applies to other "factors".

The Situation determining unit 212 combines the information on the "factor range identifiers" of the external factors to form a "Situation classification" and determines that it is "factor1-4_factor2-4_factor3-4_factor4-4_factor5-5_factor6-5_factor7-4_factor8-4".
In this way, the Situation determining unit 212 determines the "Situation classification" based on the acquired information on external factors.

Returning to FIG. 5, the operation history information generation unit 220 generates temperature distribution information 64 as a result of controlling the air conditioner 2 and air conditioning power consumption based on air conditioning control values that divide the control of the air conditioner 2 into multiple stages in each Situation. Operation history information 201 is generated based on the amount information 65.
The operation history information generation section 220 includes an air conditioning control value generation section 221, a remuneration calculation section 222, and an operation history generation section 223.

The air conditioning control value generation unit 221 generates air conditioning control values divided into multiple stages of control of the air conditioner 2 in each Situation.
Specifically, the air conditioning control value generation unit 221 sets each parameter between an upper limit value and a lower limit value for control parameters (for example, set temperature (target temperature), air volume, etc.) that can be changed in each air conditioner 2. It is divided into M stages. Then, air conditioning control value information 63 to be controlled by (one) air conditioner 2 is generated by combining the parameters of each stage.
Based on the generated air conditioning control value information 63, the air conditioning control execution unit 240 may, for example, control the air conditioners "1" → "2" → "3" in the order of air conditioners "1" → "2" → "3", or control the air conditioners "1" and "2" , Air conditioning control with multiple patterns such as controlling air conditioners ``2'' and ``3'', controlling air conditioners ``1'' and ``3'' in combination, or controlling air conditioners ``1'', ``2'', and ``3'' simultaneously. Execute.

The reward calculation unit 222 calculates a reward (temperature reward) as an index for evaluating the result of executing control using the air conditioning control value generated by the air conditioning control value generation unit 221. Then, the remuneration calculation unit 222 determines whether the control result satisfies a predetermined remuneration, that is, whether the air conditioning control value satisfies a predetermined condition.

The reward calculation unit 222 defines two types of rewards, a high temperature warning reward and a low temperature warning reward, for each air conditioning control area 20, and calculates the reward for the control result for each turn.
The high temperature warning reward is applied when the temperature before control is higher than the target temperature, that is, when the room temperature is high and the temperature is controlled to be lowered. The low temperature warning reward is applied when the temperature before control is lower than the target temperature, that is, when the room temperature is too low and the temperature is controlled to increase.

When calculating the reward, the reward calculation unit 222 uses the difference between the "target temperature of the turn" and the "temperature after turn control", that is, the deviation between the target temperature and the current temperature, as an index.
For example, in the case of a high temperature warning reward, if the "temperature after turn control" is less than or equal to the "turn target temperature", the reward is "100%". In addition, the reward will be ``-10%'' every time the ``temperature after turn control'' increases by +1 degree from the ``turn target temperature.'' Note that this reward is not limited to the above value and can be set arbitrarily.
On the other hand, in the case of low temperature warning reward, if the "temperature after turn control" is equal to or higher than the "turn target temperature", the reward is "100%". In addition, the reward will be ``-10%'' every time the ``temperature after turn control'' decreases by -1 degree from the ``turn target temperature.'' Note that this reward is not limited to the above value and can be set arbitrarily.
When the remuneration calculated by the remuneration calculation unit 222 is equal to or greater than a predetermined threshold (%), it satisfies a predetermined condition and is judged as a pass, and when it is less than a predetermined threshold (%), it is judged as a failure.

Note that the reward calculation unit 222 may determine that the test is finally passed when both the high temperature warning reward and the low temperature warning reward are passed. For example, if the initial temperature of air conditioner 2 before control is higher than the target temperature and control is performed using the air conditioning control value based on the high temperature warning reward, the predetermined passing threshold is exceeded, but the target temperature is exceeded and the temperature becomes low. There is a possibility of excessive control. In this case, excessive air conditioning power consumption occurs. Therefore, if the temperature before control is lower than the target temperature, control is performed based on the low temperature warning reward until it is determined to pass. In this manner, the reward calculation unit 222 determines that both the high temperature warning reward and the low temperature warning reward are passed, thereby making it possible to select an air conditioning control value that can be controlled within an appropriate range.

In addition, when the average temperature of the sensors in each air conditioning control area 20 (floor average temperature) after turn control is outside the prescribed range (for example, from 5°C to 35°C), the reward calculation unit 222 calculates The air conditioning control value will be rejected. Further, regarding the GPU server 4, if the GPU temperature does not fall within a predetermined range determined from the relationship between the GPU temperature (GPU card temperature) and the power consumption of the GPU server, it is judged as a failure. Regarding the accelerator 5, if the accelerator temperature does not fall within a predetermined range determined from the relationship between the accelerator temperature (temperature inside the accelerator) and power consumption, the accelerator 5 is judged to have failed. This is a process to avoid unnecessary storage of operation history that is unlikely to be adopted when the DC 10 actually processes a load and has a temperature inappropriate for managing devices within the DC 10.

The operation history creation unit 223 generates temperature distribution information 64 and air conditioning consumption as a result of the air conditioning control execution unit 240 controlling each air conditioner 2 based on the air conditioning control value information 63 generated by the air conditioning control value generation unit 221 in each Situation. The power amount information 65 is acquired.
That is, the operation history creation unit 233 causes the air conditioning control execution unit 240 to execute control for each air conditioning control value for each pattern of combinations in which each parameter is divided into M stages, generated by the air conditioning control value generation unit 221 in each Situation. , temperature distribution information 64 and air conditioning power consumption information 65 when the air conditioning control value is executed are acquired.
Note that the operation history creation unit 223 excludes from the creation of the operation history information 201 air conditioning control values and control results that the remuneration calculation unit 222 determines as failing because they do not satisfy a predetermined condition.

FIG. 7 is a diagram for explaining the temperature distribution information 64 according to this embodiment. The temperature distribution information 64 is obtained by a temperature sensor 44 provided on the suction port side of the GPU server 4 and a temperature sensor 55 provided on the suction port side of the accelerator 5, as shown in FIG. This is temperature information measured over a period of time. The

temperature sensors

44 and 55 measure temperature after their identification information is associated with the identification information of the GPU server 4 and accelerator 5 in advance. From the start to the end of the turn, all the temperature sensors 44 and 45 on the floor measure the temperature at each time transition (at predetermined time intervals), and the resulting information is generated as temperature distribution information 64.
