[0041] 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.

[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, it does not need to be further defined or explained in subsequent drawings.

[0043] Terms involved in the application documents:

[0044] 1. A UPS (Uninterruptible Power Supply) is a constant-voltage, constant-frequency uninterruptible power supply (UPS) with an energy storage device and an inverter as its primary component. It is primarily used to provide uninterrupted power to a single computer, computer network system, or other power electronic equipment.

[0045] 2. Equipment cabinets are metal cabinets used to install and store electronic equipment such as servers, network equipment, storage devices, etc. They provide a standardized, centralized space to place these devices, making management, maintenance, and wiring easier.

[0046] 3. Power equipment is a general term for equipment used for power generation, transformation, transmission, distribution, and consumption. In the context of powering equipment cabinets, these devices primarily transmit and distribute appropriate power to the cabinets to ensure the normal operation of servers and other equipment within them.

[0047] The server energy-saving rack management system described in the embodiment is mainly applied in a computer room similar to a data center. In the computer room, servers are installed in cabinets arranged in rows, and the 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 device, the higher the power distribution efficiency, the smaller the power loss of the power distribution device, and the more energy-saving the system. In addition, servers will emit a large amount of heat when running, and cooling devices are needed to continuously cool them. The computer room cooling device is generally a special air conditioner. These air conditioners will continuously deliver cool air to the computer room when the servers are working to ensure that the servers in the computer room are continuously cooled. The working load of the air conditioner is within a certain range, and the working efficiency of the air conditioner is high, and the operation is more energy-saving.

[0048] Therefore, the installation of a newly added server in which cabinet can make the working efficiency of the power distribution device that supplies power to the cabinet higher, and also make the corresponding cooling device of the cabinet work at a higher efficient operating load, which is a server energy-saving rack management problem that those skilled in the art need to solve.

[0049] Figure 1 A structural schematic diagram of a server energy-saving rack management system provided by the embodiment is provided. Figure 1 As shown in the figure, the embodiment of the present application discloses a server energy-saving rack management system, which mainly comprises a power device, a device cabinet, a first acquisition unit, a second acquisition unit and a rack management server.

[0050] Specifically, the power device is used to supply power to at least one device cabinet electrically connected to the power device. In the embodiment of the present application, the power device can convert high-voltage electricity into low-voltage electricity suitable for the device cabinet; can distribute one or more incoming power lines into multiple outgoing power lines to supply different device cabinets; can be a UPS including a rectifier, a battery pack, an inverter and a static switch, etc. When the mains is normal, it can supply the device cabinet after processing such as voltage stabilization and filtering, and charge the battery at the same time; when the mains is interrupted, the battery pack converts direct current into alternating current through the inverter to continue to supply power to the device cabinet, ensuring uninterrupted operation of the device; it can also be a device that converts the chemical energy of diesel into electrical energy, which starts as a backup power supply to provide power to the device cabinet in the case of mains power failure. Here, the specific type of the power device is not limited.

[0051] Further, the device cabinet, which can have multiple device cabinets electrically connected to one power device, or only one device cabinet electrically connected to one power device. In actual application, the device cabinet is used to supply power to at least one server and at least one air conditioner arranged in the device cabinet.

[0052] Furthermore, the first acquisition unit is mainly used to collect the electrical parameters of the power equipment, the electrical parameters of the equipment cabinet and the electrical parameters of the server. The electrical parameters here 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 power collectors.

[0054] In actual applications, servers are placed in rows within equipment cabinets, which are electrically connected to power equipment. Power equipment has varying power distribution efficiencies under varying power distribution loads. Furthermore, servers generate significant heat during operation, requiring air conditioners to continuously cool the equipment cabinets. Consequently, the air conditioners present workload and efficiency challenges. For power equipment, the higher the load, the higher the power distribution efficiency. The lower the power distribution system losses, the more energy efficient the system. For air conditioners, within a certain load range, the higher the air conditioner's operating efficiency, resulting in greater energy savings. For these reasons, embodiments of the present invention include a rack management server, which is electrically connected to a first data acquisition unit and a second data acquisition unit. The rack management server determines the available cooling capacity, cooling efficiency, and available electrical capacity of each equipment cabinet within which each air conditioner resides, based on the electrical parameters of the power equipment, the equipment cabinet, the servers, and the operating performance parameters of the air conditioners.

[0055] In this embodiment of the present invention, after the rack management server determines the available cooling capacity, cooling efficiency, and available electrical capacity of each equipment cabinet housing each air conditioner, it can sort the equipment cabinets electrically connected to the power equipment in ascending order based on these parameters. In actual applications, if servers need to be placed within the equipment cabinets, servers can be preferentially placed within the cabinets with the highest rankings based on the ranking of multiple equipment cabinets.

[0056] In an embodiment of the present invention, the rack management server can determine the cooling efficiency of each equipment cabinet electrically connected to the power equipment, the available electrical capacity of each equipment cabinet, and the available cooling capacity of each equipment cabinet housing an air conditioner 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 acquired by the first and second acquisition units. Furthermore, the server determines the availability of each equipment cabinet based on the combined results of these three parameters. The server then sorts the equipment cabinets by availability from highest to lowest, identifying the equipment cabinet with the highest availability or the one ranked first as the equipment cabinet where the newly racked server will be installed. The resulting determined equipment cabinet is then displayed with a code name. This improves the operating efficiency of the power equipment supplying the equipment cabinet and allows the air conditioner corresponding to the equipment cabinet to operate at a more efficient load, effectively addressing the energy-saving server rack management issue.

[0057] It should be noted that the first acquisition unit provided in an 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 scenario: When collecting voltage, current, power, and energy from power equipment, equipment cabinets, and servers separately:

[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. In this way, the current supplied by the AC to the power equipment can be monitored and the load of the AC input can be understood. Correspondingly, a current sensor is set on the output bus of the power equipment. The current output of the power equipment is determined based on the current sensor. In this way, it is judged 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. In this way, it is possible to monitor whether the voltage supplied by the AC power to the power equipment is within the normal range and record the fluctuation of the AC power voltage. Correspondingly, a voltage sensor is set on the output bus line of the power equipment. Based on the voltage sensor, the voltage output by the power equipment to the equipment cabinet is determined, and it is judged whether the voltage provided by the power equipment to the downstream equipment cabinet meets the working voltage requirements of the equipment cabinet.

[0061] An electric energy data sensor is arranged on the input line of the power supply device, which is used to record the electric energy supplied to the power supply device, and an electric energy data sensor is arranged on the output bus of the power supply device, which is used to count the electric energy output to the equipment cabinet. In actual application, by comparing the electric energy collected by the input and output electric energy data sensors, the energy loss of the circuit device itself can be analyzed.

[0062] According to the internal circuit structure of the power supply device, an electric power sensor is arranged near the main power conversion link, which is used to monitor the power conversion efficiency and the size of the output power of the power supply device in real time.

[0063] Further, a current sensor, a voltage sensor, an electric power sensor and an electric energy data sensor are arranged at the total input line of the equipment cabinet. In actual application, the current sensor arranged at the total input line of the equipment cabinet is used to measure the total current obtained by the entire equipment cabinet from the power supply device, so that the overall power load of the equipment cabinet can be determined. The voltage sensor arranged at the total input line of the equipment cabinet is used to determine whether the voltage entering the equipment cabinet meets the requirements of normal operation of the server. The electric power sensor arranged at the total input line of the equipment cabinet is used to determine the total electric power consumption of the equipment cabinet, and in combination with the total current and total voltage data, the energy consumption of the equipment cabinet can be understood in real time. The electric energy data sensor arranged at the total input line of the equipment cabinet is used to count the total electric energy consumption of the equipment cabinet in a period of time.

[0064] Further, a current sensor, a voltage sensor and an electric energy data sensor are arranged at the input line of the power supply module of the server, and an electric power sensor is arranged inside the server. In actual application, the current sensor can be used to understand the current change of the server in the state of starting, running different tasks and the like. The voltage sensor can ensure that the voltage received by the server meets the design requirements. The electric energy data sensor is used to record the electric energy consumed by the server during operation. The electric power sensor is used to measure the electric power consumption of the server in real time.

[0065] In one case, the voltage, current, electric power and electric energy of the power supply device, the equipment cabinet and the server are collected in a centralized manner.

[0066] The current sensor, voltage sensor, electric power sensor and electric energy data sensor are arranged at the total incoming line. Specifically, the current sensor is installed at the total incoming line of the total power room (power equipment) for arranging the equipment cabinet, for measuring the total current entering the total power room, and the current sensor can also be installed on the output bus of the power equipment, for acquiring the total current distributed to all equipment cabinets and servers; the voltage sensor is installed at the total incoming line of the total power room (power equipment) and on the output bus of the power equipment, for monitoring the voltage of the incoming power and the output voltage supplied to the equipment cabinet and server; the electric power sensor is installed at the total incoming line of the total power room (power equipment) and on the output bus of the power equipment, for acquiring the total electric power input and output of the power equipment in real time; the electric energy data sensor is installed at the total incoming line of the total power room (power equipment) and on the output bus of the power equipment, for acquiring the total electric energy input and output of the power equipment in real time.

[0067] The current sensor, voltage sensor, electric power sensor and electric energy data sensor are installed at the branch line and equipment. Specifically, the current sensor is installed at the total incoming line of each equipment cabinet, for monitoring the current acquired by each equipment cabinet from the power equipment. The current acquired here is compared and analyzed with the current data at the total incoming line, so as to understand the load condition of each equipment cabinet; the voltage sensor is installed at the total incoming line of each cabinet, for monitoring the actual working voltage of the equipment cabinet and server; the electric power sensor is installed near the total incoming line of each equipment cabinet, for acquiring the electric power data of the equipment cabinet and server; and the electric energy data sensor is installed at the total incoming line of each equipment cabinet, for recording the electric energy consumption of each equipment cabinet and server.

[0068] The server energy-saving rack management system provided by an embodiment of the present invention comprises a second collection unit including a temperature sensor, a speed sensor, and an air conditioner power and electric energy collector. The temperature sensors include a supply air temperature sensor, a return air temperature sensor, and a water temperature sensor. The supply air temperature sensor is located at the air supply outlet of the air conditioner and can collect the supply air temperature of each air conditioner. The return air temperature sensor is located at the return air outlet of the air conditioner and can collect the return air temperature of each air conditioner. The water temperature sensor is located at the water supply pipe inlet and return pipe outlet of the air conditioner using water cooling and can collect the water temperature at the water supply pipe inlet and 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. The speed sensor includes at least 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 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 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 number of wind speed sensors is adapted to the number of cooling equipment.

[0069] Furthermore, an air-conditioning power and electric energy collector is provided on the input line of the air-conditioning, and is used to measure the real-time power and accumulated electric energy consumption of the air-conditioning.

[0070] It should be noted that the wind speed sensor is used to collect the air velocity v1 at the air supply or return outlet of the air conditioner, and the air volume at the air supply or return outlet of the air conditioner is calculated by q1 = s1 × v1. Where s1 is the area of ​​the air supply or return outlet of the air conditioner, and v1 is the air velocity collected at the air supply or return outlet of the air conditioner.

[0071] The water flow sensor is used to measure the water flow rate v2 at the return pipe outlet of a water-cooled air conditioner, and calculate the water flow rate at the return pipe outlet of the air conditioner using q2 = s2 × v2, where s2 is the cross-sectional area of ​​the return pipe.

[0072] In actual applications, the computer room environment data acquisition unit includes a temperature and humidity sensor, which is installed in the middle of adjacent equipment cabinets in the computer room. Multiple sensors are installed according to the size of the computer room to collect the temperature and humidity of the computer room ambient air.

[0073] In an embodiment of the present invention, a data aggregation unit is also included, which is electrically connected to the first acquisition unit, the second acquisition unit and the cabinet rack management server respectively. The data aggregation unit is used to aggregate the data collected by the first acquisition unit and the second acquisition unit, and then transmit it to the cabinet rack management server.

[0074] Figure 2 This is a flow chart of an implementation method 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: Acquire 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; and the operating performance parameters of air conditioners include air outlet temperature, air velocity, electrical and operating status parameters.

[0076] Step 202: Determine the available cooling capacity of the equipment cabinet where each air conditioner is located and the cooling efficiency of each equipment cabinet based on the location of each air conditioner, the air outlet temperature, the air velocity, and the electrical and operating status parameters of the air conditioner. Determine the available electrical capacity of each equipment cabinet based on 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.

[0077] Step 203 : determining the availability of the equipment cabinets based on the available electrical capacity, available cooling capacity, and cooling efficiency of the equipment cabinets, and determining the equipment cabinet corresponding to the equipment cabinet with the highest availability 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 electrical parameters of power equipment, equipment racks, servers, and air conditioner operating performance parameters. In practice, electrical parameters of power equipment include current, voltage, power, and energy; electrical parameters of equipment racks include current, voltage, power, and energy; electrical parameters of servers include current, voltage, power, and energy; and operating performance parameters of air conditioners include air outlet temperature, air velocity, electrical parameters, and operating status parameters.

[0080] In step 202, the rack management server determines the available cooling capacity and cooling efficiency of each equipment cabinet where each air conditioner is located based on the location of each air conditioner, the air outlet temperature, air velocity, and electrical and operating parameters of the air conditioner. The available electrical capacity of each equipment cabinet is determined based on 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 this embodiment of the present invention, each equipment cabinet houses multiple servers and at least one air conditioner. The servers generate significant heat during operation, and the air conditioner provides cooling for the equipment cabinet. In practice, the available cooling capacity of each equipment cabinet must be determined based on relevant parameters, such as the actual heat generated by the servers within the cabinet, the ambient temperature, and the electrical and operating parameters of the air conditioner.

[0082] The available cooling capacity of an equipment cabinet is crucial for ensuring proper heat dissipation of servers and other equipment within the cabinet. In this embodiment of the present invention, the rated cooling capacity and actual cooling output of the air conditioner are taken into account. The cooling capacity that can ultimately be utilized by the cabinet is calculated by adding the air conditioner's cooling capacity adjustment coefficient and the equipment cabinet's load adjustment coefficient. Specifically, the available cooling capacity of each equipment cabinet is calculated using 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] Here, a represents the cooling capacity adjustment coefficient of the air conditioner. In actual applications, there may be problems such as improper air conditioner layout within the equipment cabinet and cooling loss due to air conditioner piping transmission. Therefore, the value of a should be less than 1. For example, in a well-designed system, a can be 0.8-0.9, indicating that a cooling loss factor of approximately 10%-20% is taken into account.

[0086] b represents the load adjustment factor for the equipment cabinet, primarily used to adjust the weight of the actual cooling output in the calculation. When b = 1, the actual cooling output is deducted entirely. The value of b can be determined based on the accuracy and reliability of the actual cooling output measurement. If the cooling output measurement is accurate, b can be set between 0.9 and 1. If there is a certain degree of measurement error or a conservative calculation is desired, b can be set between 0.7 and 0.8.

[0087] The rated cooling capacity of the air conditioner corresponding to an equipment cabinet refers to the total cooling capacity provided by all air conditioners associated with that equipment cabinet under standard operating 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 a rated cooling capacity of 3kW, the total cooling capacity is 8kW. In actual applications, the temperature and humidity of the equipment cabinet must also be considered.

[0088] ∑The cooling output of the air conditioner represents the total cooling capacity output by the air conditioner serving the equipment cabinet during actual operation. The actual cooling output 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 capacity 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, the air conditioner's return air temperature and humidity, as well as the air conditioner's outlet air temperature and humidity, must first be measured. The humidity can be obtained using a temperature and humidity sensor. Based on the air psychrometric chart, the return air enthalpy value h1 is determined by the return air temperature and humidity, while the outlet air enthalpy value h2 is determined by the outlet air temperature and humidity. Combined with the air conditioner's departure speed and air density, the air conditioner's cooling output is determined using the following formula:

[0093] Q=ρV(h1-h2) (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 its electrical parameters;

[0096] The energy efficiency ratio (EER) is a key indicator of an air conditioner's energy efficiency. If the air conditioner's input power (measured with a power meter or by checking the air conditioner's nameplate for rated power) and the EER are known, the cooling capacity can be calculated. The cooling capacity of an air conditioner is equal to the product of its rated power and the EER, which is determined by the ratio of its cooling capacity to its input power.

[0097] It should be noted that the cooling capacity of an air conditioner 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 operating conditions (usually specified by national standards, such as indoor temperature and humidity, and outdoor temperature and humidity). The unit is generally watts (W) or kilowatts (kW). It is a performance indicator of the air conditioner itself, reflecting its cooling capacity under ideal conditions.

[0098] An air conditioner's cooling output refers to the amount of heat it absorbs and removes from the equipment cabinet space per unit time under actual operating conditions. Actual operating conditions often differ from standard operating conditions, and these differences can cause cooling output to differ from 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 air conditioner's compressor operating frequency automatically adjusts based on factors such as the indoor and outdoor temperature difference and the set temperature. The higher the operating frequency, the faster the compressor speed, which speeds up the refrigerant circulation and increases the cooling capacity. The air conditioner's cooling output can be estimated based on the air conditioner's product manual.

[0101] Ambient temperature significantly affects the cooling efficiency and cooling output of an air conditioner. When the outdoor temperature rises, the air conditioner's condenser's heat dissipation efficiency decreases, causing pressure fluctuations in the refrigeration cycle and a decrease in cooling capacity. Conversely, when the indoor temperature rises, the temperature difference between indoor and outdoor increases, which, while beneficial for increasing cooling capacity to a certain extent, also limits the air conditioner's cooling capacity. The cooling output of an air conditioner can be estimated based on the actual ambient temperature and the performance curves 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 cooling output 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 air conditioner's power meter. The power meter measures voltage and current and uses the power formula to determine the air conditioner's power.

[0106] 2) Determine based on the air conditioner's nameplate parameters. The nameplate usually indicates the rated power. The rated power is the power consumed by the air conditioner under standard operating conditions.

[0107] 3) The compressor power of a fixed-frequency air conditioner is relatively stable during operation. The air conditioner's power can be determined based on the compressor's technical specifications. For example, if the compressor power of a fixed-frequency air conditioner is rated at 1kW and the fan power is 0.2kW, the total power of the air conditioner is approximately 1.2kW.

[0108] 4) The power of an inverter air conditioner is related to its operating frequency. As the operating frequency increases, the compressor speed increases, and the power also increases accordingly. The operating frequency data is obtained by the air conditioner's internal control circuit and then combined with the air conditioner's frequency-power characteristic curve to determine the power. For example, the frequency-power characteristic curve of an inverter air conditioner shows that when the operating frequency is 30Hz, the air conditioner's power is 0.5kW; when the operating frequency is 60Hz, the air conditioner's power is 1.2kW. If the air conditioner's current operating frequency is detected to be 45Hz, interpolation and other methods can be used to estimate the power at this time to be approximately 0.85kW.

[0109] Furthermore, the available power capacity of each equipment cabinet is determined based on 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 using the following formula:

[0110] Available power capacity of equipment cabinet = rated power of equipment cabinet -

[0111] Power consumption of servers installed in equipment cabinets (4)

[0112] In practical applications, the maximum current or power that a cabinet can safely and stably carry is determined as the rated power of the cabinet. Specifically, the rated power of the cabinet can be determined by:

[0113] 1) Determine the rated power of the equipment cabinet based on the cabinet's current, voltage, and first safety factor. In practice, this first safety factor is necessary to ensure safe and stable operation of the equipment cabinet. The first safety factor is a value less than 1 and is used to reduce the calculated power to account for safety factors such as electrical equipment aging and overload protection. For example, assuming the cabinet's operating voltage U = 220V, maximum operating current I = 10A, and first safety factor k1 = 0.8, the cabinet's rated power P = UIk1 = 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 reversely infer 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 cabinet's power and the second safety factor. In practical applications, if the cabinet's power under ideal conditions is known, the cabinet's rated power can be derived by introducing a second safety factor (also less than 1). This may involve adjusting the initial power estimate based on safety considerations. For example, assuming the cabinet's power under ideal conditions is P0 = 2500W and the second safety factor k2 = 0.8, the cabinet's rated power P = P0k2 = 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, where Is the power factor. The power factor reflects the power efficiency of the server, which takes into account the reactive power situation during the server's 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 range is 0.6-0.9.

[0121] 2) Determine the power consumption of the server based on 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 based on the available power capacity, available cooling capacity, and cooling efficiency of the equipment cabinets. 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 this embodiment of the present invention, the available number of equipment cabinets can be determined according to the following formula:

[0125]

[0126] Wherein, d1, d2 and d3 represent weight coefficients respectively. In this embodiment, d1, d2 and d3 may have fixed values, that is, d1=0.3, d2=0.3, d3=0.4.

[0127] Specifically, the required electrical capacity of the equipment cabinet represents the total electrical power required for normal operation of all devices in the equipment cabinet. In the embodiment of the present invention, the required electrical capacity of the equipment cabinet reflects the degree of electrical energy demanded by all devices 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 to ensure the normal operating temperature of all devices 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 a power device can be sorted in ascending order, and then the equipment cabinet with the highest value can be determined as the equipment cabinet in which the new server can be installed.

[0129] In summary, an embodiment of the present invention provides a server energy-saving rack management system and method, in which the first acquisition unit is used to obtain electrical parameters of power equipment, electrical parameters of equipment cabinets and electrical parameters of servers; the second acquisition unit is used to obtain operating performance parameters of air conditioners; the cabinet rack management server can obtain the available cooling capacity of the equipment cabinet where each air conditioner is located, the cooling efficiency of each equipment cabinet, the available power capacity of each equipment cabinet and the availability of the equipment cabinet based on the data obtained by the first acquisition unit and the second acquisition unit; further, according to the sorting of the equipment cabinet availability, the equipment cabinet with the highest value or the one ranked first can be determined as the equipment cabinet where the newly racked 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, effectively solving the problem of server energy-saving rack management.
