[0041] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 described embodiments 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 creative work should fall within the scope of protection of the present invention.
[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0043] The terms involved in the application documents:
[0044] 1.UPS (Uninterruptible Power Supply) is a constant voltage and frequency uninterruptible power supply with an energy storage device and an inverter as its main component. It is mainly used to provide uninterruptible power supply to a single computer, computer network system or other power electronic equipment.
[0045] 2. Equipment cabinet is a metal cabinet used to install and store electronic equipment such as servers, network equipment, storage devices, etc. It provides a standardized and centralized space to place these devices for easy management, maintenance and wiring.
[0046] 3. Power equipment is a general term for equipment used for power generation, transformation, transmission, distribution and consumption. In the scenario of power supply for equipment cabinets, the main function of these devices is to transmit and distribute appropriate power to the cabinets to ensure the normal operation of servers and other equipment in the cabinets.
[0047] The server energy-saving rack management system described in this embodiment is mainly used in computer rooms similar to data centers. In the computer room, servers are installed in cabinets placed in rows, and their power supply comes from one or more uninterruptible power supply devices (UPS) or similar power distribution devices installed in the computer room. These power distribution devices have different power distribution efficiencies under different power distribution loads. Generally speaking, the higher the load of the power distribution equipment, the higher the power distribution efficiency, the smaller the loss of the power distribution equipment, and the more energy-saving the system. In addition, the server will emit a lot of heat during operation, and cooling equipment is required to continuously cool them down. The cooling equipment in the computer room is generally various special air conditioners. These air conditioners will continue to deliver cold air to the computer room when the server is working to ensure that the servers in the computer room are continuously cooled. There are also workload and efficiency issues in the operation of air conditioners. When the workload is within a certain range, their work efficiency is high and the operation is more energy-saving.
[0048] Therefore, which cabinet the newly-installed server should be installed in can make the power distribution equipment that supplies power to the cabinet work more efficiently and allow the corresponding cooling equipment of the cabinet to work under a more efficient operating load. This is a server energy-saving rack management problem that technical personnel in this field urgently need to solve.
[0049] Figure 1 This is a schematic diagram of a server energy-saving rack management system provided by an embodiment of the present invention. Figure 1 As shown, an embodiment of the present invention discloses a server energy-saving rack management system, which mainly includes power equipment, equipment cabinets, a first collection unit, a second collection unit and a server rack management server.
[0050] Specifically, the power equipment is used to supply power to at least one equipment cabinet electrically connected to the power equipment. In the embodiment of the present invention, the power equipment can convert high voltage electricity into low voltage electricity suitable for use in the equipment cabinet; it can distribute one or more incoming power sources into multiple outgoing lines, which are respectively supplied to different equipment cabinets; it can be a UPS including a rectifier, a battery pack, an inverter, and a static switch. When the mains power is normal, it can stabilize and filter the mains power before supplying it to the equipment cabinet, and charge the battery at the same time; when the mains power is interrupted, the battery pack converts direct current into alternating current through an inverter, and continues to supply power to the equipment cabinet to ensure uninterrupted operation of the equipment; it can also be a device that converts the chemical energy of diesel into electrical energy. In the case of a mains power outage, it can be started as a backup power source to provide power to the equipment cabinet. Here, the specific type of power equipment is not limited.
[0051] Furthermore, the equipment cabinet may have multiple equipment cabinets electrically connected to one power device at the same time, or may have only one equipment cabinet electrically connected to one power device. In practical applications, the equipment cabinet is used to supply power to at least one server and at least one air conditioner disposed in the equipment cabinet.
[0052] Furthermore, the first acquisition unit is mainly used to collect electrical parameters of power equipment, electrical parameters of equipment cabinets and electrical parameters of servers, where the electrical parameters mainly include current, voltage, electric power and electric energy. Accordingly, the above data can be obtained through current sensors, voltage sensors, electric power sensors and computer data sensors.
[0053] Furthermore, the second acquisition unit is used to collect the operating parameters of the air conditioner, where the operating parameters mainly include air outlet temperature, air outlet speed, electrical and operating status parameters. Accordingly, the above parameters can be obtained through temperature sensors, speed sensors, air conditioning power and electric energy collectors.
[0054] In actual applications, servers are placed in rows in the equipment cabinet, and the equipment cabinet is electrically connected to the power equipment. The power equipment has different power distribution efficiency under different power distribution loads; at the same time, the server will emit a lot of heat when running, and the air conditioner is required to continuously cool the equipment cabinet. Correspondingly, there will be problems with workload and efficiency when the air conditioner is working. For power equipment, the higher the load of the power equipment, the higher the power distribution efficiency, the smaller the loss of the power distribution system of the power equipment, and the more energy-saving the system; for air conditioners, the higher the working efficiency of the air conditioner within a certain range, and the more energy-saving the operation. Based on the above reasons, the cabinet rack management server included in the embodiment of the present invention is electrically connected to the first acquisition unit and the second acquisition unit respectively. The cabinet rack management server determines the available cooling capacity of the equipment cabinet where each air conditioner is located, the cooling efficiency of each equipment cabinet, and the available power capacity of each equipment cabinet according to the electrical parameters of the power equipment, the electrical parameters of the equipment cabinet, the electrical parameters of the server, and the operating performance parameters of the air conditioner.
[0055] In the embodiment of the present invention, after the cabinet rack management server determines the available cooling capacity of the equipment cabinet where each air conditioner is located, the cooling efficiency of each equipment cabinet, and the available power capacity of each equipment cabinet, the equipment cabinets electrically connected to the power equipment can be sorted from small to large according to the above parameters. In practical applications, if it is necessary to arrange the server in the equipment cabinet, the server can be preferentially arranged in the equipment cabinet with the highest ranking according to the ranking order of multiple equipment cabinets.
[0056] In the embodiment of the present invention, the rack management server can obtain the cooling efficiency of each equipment cabinet electrically connected to the power equipment, the available power capacity of each equipment cabinet, and the available cooling capacity of the equipment cabinet where each air conditioner is located based on the electrical parameters of the power equipment, the electrical parameters of the equipment cabinet, the electrical parameters of the server, and the operating performance parameters of the air conditioner obtained by the first acquisition unit and the second acquisition unit. Further, the availability of each equipment cabinet is obtained based on the comprehensive situation of the above three parameters, and the equipment cabinet availability is sorted from large to small, and the equipment cabinet with the highest value or the first ranking is determined as the equipment cabinet where the newly-shelved server is installed, and the code name of the finally determined equipment cabinet is displayed, so that the power equipment that supplies power to the equipment cabinet can work more efficiently, and the air conditioner corresponding to the equipment cabinet can work under a more efficient operating load, which effectively solves the energy-saving rack management problem of the server.
[0057] It should be noted that the first acquisition unit provided in the embodiment of the present invention includes multiple current sensors, multiple voltage sensors, multiple electric power sensors and multiple electric energy data sensors; in actual applications, the voltage, current, electric power and electric energy of the power equipment, equipment cabinets and servers can be collected separately, or the voltage, current, electric power and electric energy of the power equipment, equipment cabinets and servers can be collected centrally.
[0058] One case: When collecting the voltage, current, power and energy of power equipment, equipment cabinets and servers respectively:
[0059] A current sensor is set on the AC input line of the power equipment. The current sensor is used to measure the input current from the AC to the power equipment, so as to monitor the current supplied by the AC to the power equipment and understand the load condition of the AC input. Correspondingly, a current sensor is set on the output bus line of the power equipment. The current output by the power equipment is determined based on the current sensor, so as to judge whether the current provided by the power equipment to the downstream equipment cabinet meets the requirements. It can also be used to calculate parameters such as the output power of the power equipment.
[0060] A voltage sensor is set on the AC power input line of the power equipment. The current sensor is used to measure the input voltage from the AC power to the power equipment, so that it is possible to monitor whether the voltage supplied from the AC power to the power equipment is within the normal range, and to record the fluctuation of the AC power voltage; accordingly, a voltage sensor is set on the output bus line of the power equipment, and the voltage output by the power equipment to the equipment cabinet is determined based on the voltage sensor, and it is judged whether the voltage provided by the power equipment to the downstream equipment cabinet meets the working voltage requirement of the equipment cabinet.
[0061] An electric energy data sensor is set on the AC power input line of the power equipment, which is used to record the electric energy supplied to the power equipment by the AC power.

[0064] Furthermore, current sensors, voltage sensors, and electric energy data sensors are respectively set on the input lines of the power module of the server, and electric power sensors are set inside the server. In practical applications, setting a current sensor can understand the current changes of the server when it is started and running different tasks; setting a voltage sensor can ensure that the voltage received by the server meets its design requirements; setting an electric energy data sensor is used to record the electric energy consumed by the server during operation; and setting an electric power sensor is used to measure the electric power consumption of the server in real time.
[0065] In one case, the voltage, current, power and energy of power equipment, equipment cabinets and servers are collected centrally:
[0066] Current sensors, voltage sensors, electric power sensors, and electric energy data sensors are centrally arranged at the main incoming line. Specifically, a current sensor is installed at the main incoming line of the main machine room (electrical equipment) for setting up equipment cabinets to measure the total current entering the main machine room. At the same time, a current sensor can also be installed on the output bus of the electric equipment. This sensor is used to obtain the total current distributed to all equipment cabinets and servers; a voltage sensor is installed at the main incoming line of the main machine room (electrical equipment) and on the output bus of the electric equipment to monitor the main voltage entering the electric equipment and the output voltage supplied to the equipment cabinet and server; an electric power sensor is installed at the main incoming line of the main machine room (electrical equipment) and on the output bus of the electric equipment to obtain the total electric power input and output of the electric equipment in real time; an electric energy data sensor is installed at the main incoming line of the main machine room (electrical equipment) and on the output bus of the electric equipment to obtain the total electric energy input and output of the electric equipment in real time.

Specifically, install a current sensor at the main incoming line of each equipment cabinet to monitor the current obtained by each equipment cabinet from the power equipment. The current obtained here is compared and analyzed with the current data at the main incoming line to understand the load condition of each equipment cabinet; install a voltage sensor at the main incoming line of each cabinet to monitor the actual working voltage of the equipment cabinet and server. Install an electric power sensor near the main incoming line of each equipment cabinet to obtain the electric power data of the equipment cabinet and server; install an electric energy data sensor at the main incoming line of each equipment cabinet to record the power consumption of each equipment cabinet and server.

Among them, the temperature sensor includes a supply air temperature sensor, a return air temperature sensor and a water temperature sensor, wherein the supply air temperature sensor is arranged at the air supply port of the air conditioner, and can collect the supply air temperature of each air conditioner; the return air temperature sensor is arranged at the return air port of the air conditioner, and can collect the return air temperature of each air conditioner; the water temperature sensor is arranged at the water supply pipe inlet and the return pipe outlet of the air conditioner that adopts water cooling, and can collect the water temperature at the water supply pipe inlet and the return pipe outlet of the air conditioner; the number of the above-mentioned multiple temperature sensors corresponds to the number of air conditioners, and the specific number is not limited again. The speed sensor at least includes a wind speed sensor, which is respectively arranged at the air supply outlet and return air outlet of the air conditioner, and can collect the air supply volume at the air supply outlet and return air outlet of the air conditioner. The number of wind speed sensors arranged is adapted to the number of cooling equipment. At the same time, multiple wind speed sensors can be installed on one air conditioner at the same time according to the size of the air supply outlet or the return air outlet; it also includes a water flow sensor, which is arranged on the return pipe of the air conditioner that adopts water cooling, and can collect the water flow at the return pipe outlet of the air conditioner.

The data aggregation unit is used to aggregate the data collected by the first collection unit and the second collection unit, and then transmit it to the cabinet rack management server.
[0074] Figure 2 A flowchart of a server energy-saving rack management method provided by an embodiment of the present invention. Figure 2 As shown, based on the same technical concept, an embodiment of the present invention provides a server energy-saving rack management method, which mainly includes the following steps:
[0075] Step 201, obtaining electrical parameters of power equipment, electrical parameters of equipment cabinets, electrical parameters of servers, and operating performance parameters of air conditioners, wherein the electrical parameters of power equipment include current, voltage, electric power, and electric energy; the electrical parameters of equipment cabinets include current, voltage, electric power, and electric energy; the electrical parameters of servers include current, voltage, electric power, and electric energy; the operating performance parameters of air conditioners include air outlet temperature, air outlet speed, electrical and operating status parameters;
[0076] Step 202, determining the available cooling capacity of the equipment cabinet where each air conditioner is located and the cooling efficiency of each equipment cabinet according to the installation position of each air conditioner, the air outlet temperature, the air outlet speed, the electrical and operating status parameters of the air conditioner; determining the available power capacity of each equipment cabinet according to the input current and voltage of each equipment cabinet, the number of servers installed in each of the equipment cabinets, and the input current and voltage of each server;
[0077] Step 203, determining the availability of the equipment cabinets according to the available power capacity of the multiple equipment cabinets, the available cooling capacity of the multiple equipment cabinets, and the cooling efficiency of the equipment cabinets, and determining the equipment cabinet corresponding to the equipment cabinet with the highest value of the availability of the equipment cabinet as the cabinet in which the new server can be installed.
[0078] It should be noted that the execution subject of the above process is the cabinet rack management server, such as Figure 1 As shown, the cabinet rack management server is electrically connected to the first collection unit and the second collection unit respectively.
[0079] In step 201, the rack management server obtains the electrical parameters of the power equipment, the electrical parameters of the equipment rack, the electrical parameters of the server, and the operating performance parameters of the air conditioner. In practical applications, the electrical parameters of the power equipment include current, voltage, electric power, and electric energy; the electrical parameters of the equipment rack include current, voltage, electric power, and electric energy; the electrical parameters of the server include current, voltage, electric power, and electric energy; the operating performance parameters of the air conditioner include air outlet temperature, air outlet speed, electrical and operating status parameters.

The available power capacity of each equipment cabinet is determined according to the input current and voltage of each equipment cabinet, the number of servers installed in each equipment cabinet, and the input current and voltage of each server.
[0081] In the embodiment of the present invention, multiple servers and at least one air conditioner are arranged in each equipment cabinet. The servers will generate a lot of heat during operation, and the function of the air conditioner is to provide a cold source for the equipment cabinet. In practical applications, the available cooling capacity of each equipment cabinet needs to be determined based on the actual heat generated by the servers in the equipment cabinet, the ambient temperature, and the electrical and operating parameters of the air conditioner and other related parameters.
[0082] The available cooling capacity of the equipment cabinet is very important to ensure the normal heat dissipation of the server and other equipment in the equipment cabinet. In the embodiment of the present invention, the rated cooling capacity and the actual output cooling capacity of the air conditioner are taken into account, and the cooling capacity that can be finally utilized by the cabinet is comprehensively calculated by adding the cooling capacity adjustment coefficient of the air conditioner and the load adjustment coefficient of the equipment cabinet. Specifically, the available cooling capacity of each equipment cabinet is calculated by the following formula:
[0083] Available cooling capacity of equipment cabinet = a × ∑ Rated cooling capacity of the air conditioner corresponding to the equipment cabinet -
[0084] b×∑ cooling output of air conditioner (1)
[0085] Among them, a represents the cooling capacity adjustment coefficient of the air conditioner. In actual applications, there may be unreasonable layout of the air conditioner in the equipment cabinet, cooling capacity loss in the air conditioner pipeline, etc., so the value of a here should be less than 1. For example, in a system with a relatively reasonable design, a can be 0.8-0.9, which means that about 10%-20% cooling capacity loss factor is taken into account.
[0086] b represents the load adjustment factor of the equipment cabinet, which is mainly used to adjust the weight of the actual output cooling capacity in the calculation. When b = 1, it means that the deduction is made completely according to the actual output cooling capacity. The value of b can be determined based on the accuracy and reliability of the measurement of the actual output cooling capacity. If the measurement of the output cooling capacity is relatively accurate, b can be 0.9-1; if there is a certain error in the measurement or conservative calculation is desired, b can be 0.7-0.8.
[0087] ∑ The rated cooling capacity of the air conditioner corresponding to the equipment cabinet refers to the total cooling capacity that all air conditioners related to the equipment cabinet can provide under standard working conditions. For example, if an equipment cabinet is equipped with two air conditioners, one with a rated cooling capacity of 5kW and the other with 3kW, then the total cooling capacity is 8kW. In practical applications, the temperature and humidity of the equipment cabinet must also be considered.
[0088] ∑The output cooling capacity of the air conditioner represents the total cooling capacity output by the air conditioner serving the equipment cabinet during actual operation. The actual output cooling capacity of the air conditioner will be affected by many factors.
[0089] In the embodiment of the present invention, the cooling output of the air conditioner can be determined by the following methods:
[0090] 1) Determine the cooling output of the air conditioner based on the air outlet temperature, return air temperature and enthalpy difference method;
[0091] The enthalpy difference method is based on the law of conservation of energy. It calculates the cooling capacity by measuring the change in enthalpy between the return air (the air entering the air conditioner) and the outlet air (the air blown out after being treated by the air conditioner).
[0092] Specifically, we first need to measure the return air temperature and humidity of the air conditioner and the outlet air temperature and humidity of the air conditioner. The humidity here can be obtained by a temperature and humidity sensor. According to the enthalpy and humidity diagram of the air, the enthalpy value h of the return air is determined by the temperature and humidity of the return air. 1 , determine the enthalpy value h of the outlet air through the outlet air temperature and humidity 2 , combined with the air unit's departure speed and air density, the output cooling capacity of the air conditioner is determined by the following formula:
[0093] Q=ρV(h 1 -h 2 ) (2)
[0094] Among them, Q represents the cooling output of the air conditioner, ρ represents the air density, and V represents the air supply volume of the air conditioner, and its unit is m 3 / s,m 3 represents volume and s represents time.
[0095] 2) Determine the cooling output of the air conditioner based on the electrical parameters of the air conditioner;
[0096] The energy efficiency ratio is an important indicator to measure the energy efficiency of air conditioners. If the input power of the air conditioner (which can be measured by a power meter or the rated power can be obtained by looking at the air conditioner nameplate) and the energy efficiency ratio are known, the cooling capacity can be calculated. The cooling output of the air conditioner is equal to the product of the rated power of the air conditioner and the energy efficiency ratio, and the energy efficiency ratio can be determined based on the ratio of the cooling capacity of the air conditioner to the input power.
[0097] It should be noted that the cooling capacity of an air conditioner here refers to the total amount of heat removed from a confined space, room or area per unit time when the air conditioner is operating under standard conditions (usually specified by national standards, such as indoor temperature, humidity and outdoor temperature, humidity and other specific conditions). The unit is generally watts (W) or kilowatts (kW). It is a performance indicator of the air conditioner itself, reflecting the cooling capacity of the air conditioner under ideal conditions.
[0098] The cooling output of an air conditioner refers to the amount of heat that the air conditioner can actually absorb and transfer from the space where the equipment cabinet is located per unit time under the actual operating environment. There are often differences between the actual operating environment and the standard operating conditions, and these differences will cause the cooling output to be different from the cooling capacity.
[0099] 3) Determine the cooling output of the air conditioner based on the operating status parameters of the air conditioner and the ambient temperature.
[0100] The operating frequency of the air conditioner's compressor will automatically adjust according to factors such as the indoor and outdoor temperature difference and the set temperature. The higher the operating frequency, the faster the compressor speed, the faster the refrigerant circulation speed, and the greater the cooling capacity. The output cooling capacity of the air conditioner can be estimated according to the air conditioner product manual;
[0101] The ambient temperature has a significant impact on the cooling effect and output cooling capacity of the air conditioner. When the outdoor ambient temperature rises, the heat dissipation efficiency of the air conditioner's condenser decreases, resulting in changes in the pressure of the refrigeration cycle and a decrease in cooling capacity; when the indoor ambient temperature rises, the temperature difference between indoor and outdoor increases, which is beneficial to increase the cooling capacity to a certain extent, but it is also limited by the upper limit of the air conditioner's cooling capacity. The output cooling capacity of the air conditioner can be estimated based on the actual ambient temperature and the performance curve provided by the manufacturer.
[0102] Furthermore, the cooling efficiency of the cooling equipment corresponding to the equipment cabinet is calculated by the following formula:
[0103] Cooling efficiency of equipment cabinet = cooling output of air conditioner / power of air conditioner (3)
[0104] The output cooling capacity of the air conditioner can refer to the above-mentioned method; the power of the air conditioner can be determined according to the electrical and operating state parameters of the air conditioner, specifically, including the following methods:
[0105] 1) Directly measure the input power of the air conditioner using the power meter of the air conditioner. The power meter measures the voltage and current and determines the power of the air conditioner based on the power formula.
[0106] 2) Determine based on the nameplate parameters of the air conditioner. The nameplate of the air conditioner usually has the rated power information. The rated power is the power consumed by the air conditioner under standard operating conditions.
[0107] 3) When the compressor of a fixed-frequency air conditioner is running, its power is relatively stable. The air conditioner power can be determined by the technical parameters of the compressor. For example, if the rated power of the compressor of a fixed-frequency air conditioner is 1kW and the fan power is 0.2kW, the total power of the air conditioner is about 1.2kW.
[0108] 4) The power of a variable frequency air conditioner is related to the operating frequency. As the operating frequency increases, the compressor speed increases and the power increases accordingly. The operating frequency data is obtained through the control circuit inside the air conditioner, and then combined with the frequency-power characteristic curve of the air conditioner to determine the power. For example, the frequency-power characteristic curve of the variable frequency air conditioner shows that when the operating frequency is 30Hz, the power of the air conditioner is 0.5kW; when the operating frequency is 60Hz, the power of the air conditioner is 1.2kW. If it is detected that the current operating frequency of the air conditioner is 45Hz, the power at this time can be estimated to be approximately 0.85kW through interpolation and other methods.
[0109] Furthermore, the available power capacity of each equipment cabinet is determined according to the input current and voltage of each equipment cabinet, the number of servers installed in each equipment cabinet, and the input current and voltage of each server. Specifically, the available power capacity of each equipment cabinet is calculated by the following formula:
[0110] Available power capacity of equipment cabinet = rated power of equipment cabinet -
[0111] Power consumption of installed servers in equipment cabinets (4)
[0112] In practical applications, the maximum current or power that the equipment cabinet can safely and stably carry is determined as the rated power of the equipment cabinet. Specifically, the rated power of the equipment cabinet can be determined by the following methods:
[0113] 1) Determine the rated power of the equipment cabinet based on the current, voltage and first safety factor of the equipment cabinet; in practical applications, in order to ensure that the equipment cabinet can operate safely and stably, it is necessary to introduce the first safety factor. The first safety factor is a value less than 1, which is used to reduce the calculated power to take into account safety factors such as aging of electrical equipment and overload protection. For example, assuming that the working voltage of the equipment cabinet is U = 220V, the maximum working current is I = 10A, and the first safety factor k 1=0.8, then the rated power of the equipment cabinet P = UIk 1 =1760W.
[0114] It should be noted that the value range of the first safety factor is 0.6-0.8.
[0115] 2) Determine the rated power of the equipment cabinet based on the power consumed by the equipment cabinet at a set time; if you know the power W (in joules or kilowatt-hours) consumed by the equipment cabinet at a set time, you can use the formula (where t is the set time) to calculate the electric power. This method is to reverse the electric power that the equipment cabinet can bear from the perspective of energy consumption.
[0116] 3) Determine the rated power of the equipment cabinet based on the power of the equipment cabinet and the second safety factor. In practical applications, if the power of the equipment cabinet under a certain ideal state is known, the rated power of the equipment cabinet is obtained by introducing a second safety factor (also a value less than 1). This may be based on a preliminary power estimate and adjustments are made considering safety factors. For example, assuming that the power of the equipment cabinet under an ideal state is P 0 =2500W, second safety factor k 2 =0.8, then the rated power of the equipment cabinet P = P 0 k 2 =2000W.
[0117] It should be noted that the value range of the second safety factor is 0.8-0.9.
[0118] Furthermore, the power consumption of the server can be determined by:
[0119] 1) Determine the power consumption of the server based on the current, voltage and power factor of the server. For the server, its power consumption can be calculated according to the electrical formula To calculate, The power factor reflects the power efficiency of the server, which takes into account the reactive power of the server during power consumption. For example, if the server's operating voltage U = 220V and the operating current I = 3A, the power factor Then the power consumption of the server
[0120] It should be noted that the power factor ranges from 0.6 to 0.9.
[0121] 2) Determine the power consumption of the server according to the power consumption of the server;
[0122] 3) Determine the power consumption of the server based on the power consumed by the server at the set time. Calculate the power consumption of the server based on the power consumed by the server at the set time, also using the formula
[0123] In step 203, the equipment cabinet availability is determined according to the available power capacity of the multiple equipment cabinets, the available cooling capacity of the multiple equipment cabinets, and the cooling efficiency of the equipment cabinets, and the equipment cabinet corresponding to the equipment cabinet availability with the highest value is determined as the cabinet in which the new server can be installed.
[0124] In the embodiment of the present invention, the available quantity of equipment cabinets can be determined according to the following formula:
[0125]
[0126] Among them, d 1 ,d 2 and d 3 Denote weight coefficients respectively. In this embodiment, d 1 ,d 2 and d 3 It can be determined as a fixed value, that is, d 1 =0.3,d 2 =0.3,d 3 =0.4.
[0127] Specifically, the required electrical capacity of the equipment cabinet represents the total electrical power required for normal operation of all equipment in the equipment cabinet. In the embodiment of the present invention, the required electrical capacity of the equipment cabinet reflects the degree of demand for electrical energy of all equipment installed in the equipment cabinet. The required cooling capacity of the equipment cabinet represents the total heat that needs to be removed from the equipment cabinet in order to ensure the normal operating temperature of all equipment in the equipment cabinet. This is a key parameter to ensure that the equipment cabinet does not experience performance degradation, failure or even damage due to overheating.
[0128] In an embodiment of the present invention, after the availability of each equipment cabinet is determined, the availabilities of multiple equipment cabinets electrically connected to an electric power device can be sorted in ascending order, and then an equipment cabinet with the highest value is determined as the equipment cabinet in which the new server can be installed.
