[0027] refer to Figure 1 The system shown, Figure 2This diagram illustrates a cooling capacity regulation control method according to an embodiment of this application. The method is applied to a cooling capacity regulation control system, which includes a control device and a refrigerant distribution device. The method includes steps S11, S12, S13, S14, and S15. In step S11, the control device collects server status information corresponding to one or more servers. In step S12, the control device determines a corresponding cooling capacity regulation command based on the server status information, wherein the cooling capacity regulation command matches at least one target server among the one or more servers. In step S13, the control device sends the cooling capacity regulation command to the refrigerant distribution device corresponding to the at least one target server. In step S14, the refrigerant distribution device receives the cooling capacity regulation command sent by the control device. In step S15, the refrigerant distribution device, based on the cooling capacity regulation command, controls the corresponding target refrigeration device to perform a first cooling capacity regulation operation.

[0028] In step S11, the control device collects server status information corresponding to one or more servers. In some embodiments, the control device can obtain the corresponding server status information from one or more servers in one or more corresponding racks via wired or wireless transmission.

[0029] In some embodiments, the server status information includes at least one of the following: temperature information corresponding to each of the one or more servers; hardware fan status information corresponding to each of the one or more servers; load information corresponding to each of the one or more servers; and server operation information of the rack corresponding to each of the one or more servers.

[0030] In some embodiments, the temperature information corresponding to each server includes, but is not limited to, the server's real-time inlet temperature, outlet temperature, GPU temperature, or CPU temperature.

[0031] In some embodiments, if the hardware fan of the server is faulty, the hardware fan status information corresponding to each server includes, but is not limited to, the fault information of the current hardware fan of the server; if the hardware fan of the server is operating normally, the hardware fan status information corresponding to each server includes, but is not limited to, the operating information of the current hardware fan of the server.

[0032] In some embodiments, the load information corresponding to each server includes, but is not limited to, the server's current resource usage, runtime, and average load.

[0033] In some embodiments, the server operation information for each server rack includes, but is not limited to, the number of servers in the rack and the real-time server status information. The real-time server status information includes, but is not limited to, the number of servers currently running in the rack. In some embodiments, the server status information also includes server identification information or rack identification information for each of the one or more servers.

[0034] In step S12, the control device determines a corresponding cooling capacity adjustment command based on the server status information, wherein the cooling capacity adjustment command matches at least one target server among the one or more servers.

[0035] For example, if the server status information indicates that the target server has a low temperature, low load, or few servers in its rack, the control device can determine a cooling capacity adjustment command for that target server. This command could reduce the fan speed or water flow rate of the target cooling equipment, thereby reducing energy consumption and maintaining the ambient temperature of the target server within a suitable range. Conversely, if the server status information indicates that the target server has a high temperature, a faulty fan, high load, or many servers in its rack, the control device can determine a cooling capacity adjustment command for that target server. This command could increase the fan speed or water flow rate of the target cooling equipment to improve heat dissipation. In some embodiments, the cooling capacity adjustment command includes one or more adjustment commands, each of which is matched with one of the at least one target server.

[0036] In some embodiments, the control device pre-stores multiple cooling capacity adjustment strategies. The control device can determine a cooling capacity adjustment strategy that matches the server status information based on the server status information, and then determine a corresponding cooling capacity adjustment instruction based on the matched cooling capacity adjustment strategy (for example, different cooling capacity adjustment strategies are adapted to different server status information, each cooling capacity adjustment strategy contains one or more cooling capacity adjustment instructions about its corresponding server status information, and the control device can determine the corresponding cooling capacity adjustment instruction based on the determined cooling capacity adjustment strategy). The cooling capacity adjustment instruction can be used to adjust the target cooling device corresponding to the target server corresponding to the server status information.

[0037] In step S13, the control device sends the cooling capacity adjustment command to the cooling liquid distribution device corresponding to the at least one target server.

[0038] In some embodiments, the coolant distribution device can control the cooling equipment corresponding to each of one or more server racks. One or more servers are housed in the server racks. The control device determines a coolant distribution device that can control the target cooling equipment corresponding to the at least one target server based on the target server, and sends the cooling capacity adjustment command to the corresponding coolant distribution device.

[0039] In some embodiments, if the cooling capacity adjustment command includes multiple adjustment commands, each of which corresponds to a plurality of target servers, and if at least two of the plurality of target servers correspond to different coolant distribution devices, the control device can send cooling capacity adjustment commands to the at least two coolant distribution devices respectively, thereby controlling the heat dissipation of different servers in the data center by sending cooling capacity adjustment commands to the plurality of coolant distribution devices respectively.

[0040] In some embodiments, the server status information further includes server identification information or rack identification information corresponding to each of the one or more servers; the method further includes step S17 (not shown), in which the control device determines the corresponding coolant distribution device based on the server identification information or rack identification information corresponding to the at least one target server. In some embodiments, the control device stores a mapping relationship between servers, racks, and coolant distribution devices, such as a mapping relationship between servers and racks, a mapping relationship between racks and coolant distribution devices, or a mapping relationship between servers and coolant distribution devices. Before step S13, the control device can determine the corresponding coolant distribution device based on the server identification information or rack identification information corresponding to the at least one target server in the server status information, and the mapping relationship between servers, racks, and coolant distribution devices, so as to accurately send the cooling capacity adjustment command to the corresponding coolant distribution device.

[0041] In step S14, the refrigerant distribution device receives the cooling capacity adjustment command sent by the control device. In step S15, based on the cooling capacity adjustment command, the refrigerant distribution device controls the corresponding target refrigeration device to perform a first cooling capacity adjustment operation.

[0042] In some embodiments, the cooling capacity adjustment command includes one or more adjustment commands and server identification information of the target server corresponding to each adjustment command. The refrigerant distribution device determines one or more target adjustment commands that match the device based on the server identification information of the target server corresponding to each adjustment command. The target server corresponding to each of the one or more target adjustment commands belongs to the rack of the refrigeration equipment managed by the refrigerant distribution device. The refrigerant distribution device can determine the target refrigeration equipment corresponding to the rack based on the rack to which the target server belongs. Based on the target adjustment command, the refrigerant distribution device controls the target refrigeration equipment to perform a corresponding first cooling capacity adjustment operation, such as controlling the fan speed or water flow rate of the target refrigeration equipment.

[0043] In some embodiments, step S15 includes: the refrigerant distribution device determining whether the cooling capacity adjustment command matches the refrigerant distribution device; if so, the refrigerant distribution device, based on the cooling capacity adjustment command, controls the corresponding target refrigeration equipment to perform a first cooling capacity adjustment operation. In some embodiments, after receiving the cooling capacity adjustment command, the refrigerant distribution device first checks the cooling capacity adjustment command to determine whether it matches the refrigerant distribution device, in order to avoid the control device issuing commands erroneously. For example, the refrigerant distribution device determines, based on one or more target servers corresponding to the cooling capacity adjustment command, whether there is a server belonging to the cabinet of the refrigeration equipment it manages among the one or more target servers. If there is, the cooling capacity adjustment command matches the refrigerant distribution device. The refrigerant distribution device then controls the corresponding target refrigeration equipment to perform the first cooling capacity adjustment operation based on the cooling capacity adjustment command. If there is no server, the cooling capacity adjustment command does not match the refrigerant distribution device, and the refrigerant distribution device can ignore the cooling capacity adjustment command. The refrigerant distribution device can also return corresponding erroneous information to the control device.

[0044] In some embodiments, if the refrigerant distribution device receives multiple cooling capacity adjustment commands targeting the same refrigeration device within a preset time period (e.g., 30 seconds, 5 minutes, 10 minutes, etc.), the refrigerant distribution device can determine one adjustment command to be executed from these multiple target adjustment commands. Based on this adjustment command, the device controls the target refrigeration device to perform a first cooling capacity adjustment operation, thereby avoiding frequent changes in the operating state of the target refrigeration device within a short period of time. In some embodiments, the refrigerant distribution device can determine the corresponding adjustment command to be executed based on the type information of the multiple target adjustment commands. For example, if the type information of the multiple target adjustment commands is the same, such as all commands instructing the target refrigeration device to increase fan speed or water flow rate, or all commands instructing the target refrigeration device to decrease fan speed or water flow rate, the refrigerant distribution device can select the adjustment command corresponding to the maximum, minimum, or average increase / decrease value among the multiple target adjustment commands as the adjustment command to be executed. If the types of the multiple target adjustment commands are different, for example, if the multiple target adjustment commands include decreasing and increasing fan speed and water flow rate, the coolant distribution device can obtain the target cooling status information of the target cooling equipment from the target cooling equipment, and perform corresponding cooling capacity adjustment operations on the target cooling equipment based on the target cooling status information. For example, if the target cooling status information shows that the ambient temperature of the cabinet corresponding to the target cooling equipment is higher than the preset temperature, the coolant distribution device controls the target cooling equipment to increase the fan speed or water flow rate, etc.; or if the target cooling status information shows that the ambient temperature of the cabinet corresponding to the target cooling equipment is lower than the preset temperature, the coolant distribution device controls the target cooling equipment to decrease the fan speed or water flow rate, etc.

[0045] In some embodiments, the control device determining the corresponding cooling capacity adjustment instruction based on the server status information includes: the control device determining whether there is at least one target server among the one or more servers that meets the cooling capacity adjustment conditions; if so, the control device determining the corresponding cooling capacity adjustment instruction based on the server status information corresponding to the at least one target server.

[0046] For example, the control device first determines whether there are servers outside the suitable operating temperature based on the collected server status information. If so, the server can be identified as the target server that meets the cooling capacity adjustment conditions, and the corresponding cooling capacity adjustment command can be determined based on the server status information corresponding to the target server. The server status information corresponding to the target server includes, but is not limited to, the temperature information, hardware fan status information, load information, and server operation information of the rack corresponding to the target server. Here, the method by which the control device determines the corresponding cooling capacity adjustment command based on the server status information corresponding to at least one target server is the same as or similar to the determination method in step S12 above, and therefore will not be repeated here, but is included by reference. In some embodiments, for servers whose server status information does not meet the cooling capacity adjustment conditions, the control device can ignore the server status information corresponding to the server and not send a cooling capacity adjustment command for the server.

[0047] In some embodiments, the cooling capacity adjustment conditions include at least one of the following: the temperature information corresponding to the target server exceeds a preset temperature range; the hardware fan status information corresponding to the target server contains fault information; the load information corresponding to the target server exceeds a preset load range; the server operation information of the rack corresponding to the target server meets the corresponding rack server operation conditions.

[0048] For example, if the inlet temperature, outlet temperature, GPU temperature, or CPU temperature of the target server is higher than the preset temperature range, the hardware fan is faulty, the target server's current resource usage is high, the average load is high and exceeds the preset load range, or the number of servers in the rack corresponding to the target server is large or the number of currently running servers exceeds the preset number range, then the operating temperature of the target server may be high and exceed the suitable operating temperature range. In this case, the target server needs to be adjusted accordingly to ensure that it is within the suitable operating temperature range.

[0049] For example, if the inlet temperature, outlet temperature, GPU temperature, or CPU temperature of the target server is lower than the preset temperature range, the current resource usage of the target server is lower than the preset load range, the number of servers in the rack corresponding to the target server is small or the number of currently running servers is small than the preset number range, then the operating temperature of the target server may be lower than the suitable operating temperature range. In this case, the target server needs to be adjusted accordingly to ensure that it is within the suitable operating temperature range.

[0050] In some embodiments, the control device determining the corresponding cooling capacity adjustment instruction based on the server status information corresponding to the at least one target server includes: the control device determining a cooling capacity adjustment strategy that matches the cooling capacity adjustment conditions met by the at least one target server; and the control device determining the corresponding cooling capacity adjustment instruction based on the cooling capacity adjustment strategy and the server status information corresponding to the at least one target server.

[0051] For example, the control device pre-stores multiple cooling capacity adjustment strategies, each matched with different cooling capacity adjustment conditions. These strategies can provide different cooling capacity adjustment instructions corresponding to different server status information of the target server under the given cooling capacity adjustment conditions. For instance, if the cooling capacity adjustment condition satisfied by at least one target server is that the temperature information of the target server exceeds a preset temperature range, the determined matching cooling capacity adjustment strategy may include cooling capacity adjustment instructions matched for different temperatures of the target server (e.g., different fan speeds or water flow rates of the cooling equipment at different temperatures). Similarly, if the cooling capacity adjustment condition satisfied by at least one target server is that the hardware fan status information of the target server contains fault information, the determined matching cooling capacity adjustment strategy may include cooling capacity adjustment instructions corresponding to different fault types of the target server. If the cooling capacity adjustment condition satisfied by at least one target server is that the load information of the target server exceeds a preset load range, the determined matching cooling capacity adjustment strategy may include cooling capacity adjustment instructions matched for different loads of the target server. If the cooling capacity adjustment condition satisfied by the at least one target server is that the server operation information of the corresponding rack of the target server meets the corresponding rack server operation conditions, then the determined matching cooling capacity adjustment strategy may include cooling capacity adjustment instructions matched under the server operation information of different racks. In some embodiments, if the cooling capacity adjustment conditions satisfied by the at least one target server are multiple, the control device determines a cooling capacity adjustment strategy matching each cooling capacity adjustment condition; and based on the cooling capacity adjustment strategy and the server status information corresponding to the at least one target server, determines intermediate adjustment instructions under that cooling capacity adjustment condition; and then determines the corresponding cooling capacity adjustment instructions according to the determined intermediate adjustment instructions. For example, the average or extreme value of each intermediate adjustment instruction can be taken to determine the corresponding cooling capacity adjustment instructions.

[0052] In some embodiments, the method further includes step S16 (not shown), wherein the control device acquires first cooling status information of the first cooling device corresponding to the one or more servers; the control device determines the corresponding cooling capacity adjustment command based on the server status information, including: the control device determines the corresponding cooling capacity adjustment command based on the server status information and the first cooling status information.

[0053] For example, the control device can determine the rack to which the one or more servers belong, and obtain first cooling status information from the first cooling device corresponding to the rack via wired or wireless transmission. The first cooling status information includes, but is not limited to, the ambient temperature information of the rack corresponding to the first cooling device. The control device can combine this first cooling status information to determine the corresponding cooling capacity adjustment command. For example, if the first cooling status information shows that the ambient temperature of the rack corresponding to the first cooling device exceeds the ambient temperature range, cooling capacity adjustment is required. The control device can determine the intermediate adjustment command corresponding to the first cooling status information based on the ambient temperature of the rack (e.g., if the ambient temperature of the rack is too high, the fan speed or water flow rate of the first cooling device needs to be increased; if the ambient temperature of the rack is too low, the fan speed or water flow rate of the first cooling device needs to be decreased). The control device determines the corresponding cooling capacity adjustment command based on the intermediate adjustment command and the server status information of the server matched with the first cooling device. The control device can determine the intermediate adjustment command corresponding to the server status information based on the server status information of the server matched with the first cooling device in the same or similar manner as described above for determining the corresponding cooling capacity adjustment command based on the server status information corresponding to the at least one target server. Then, based on the intermediate adjustment command corresponding to the first cooling status information and the intermediate adjustment command corresponding to the server status information, the corresponding cooling capacity adjustment command is determined.

[0054] In some embodiments, the control device determining the corresponding cooling capacity adjustment command based on the server status information and the first cooling status information includes: the control device determining whether there is a cooling capacity adjustment condition matching the first cooling status information; if so, the control device determining the corresponding cooling capacity adjustment command based on the cooling capacity adjustment condition matching the first cooling status information, the server status information, and the first cooling status information; otherwise, the control device determining the corresponding cooling capacity adjustment command based on the server status information.

[0055] In some embodiments, the cooling capacity adjustment condition further includes the ambient temperature of the cabinet corresponding to the first cooling device exceeding the ambient temperature range. If the first cooling status information satisfies the aforementioned cooling capacity adjustment condition, then there exists a cooling capacity adjustment condition matching the first cooling status information. In some embodiments, if there exists a cooling capacity adjustment condition matching the first cooling status information, the control device determines the cooling capacity adjustment condition satisfied by the corresponding server based on the server status information. The control device determines a corresponding cooling capacity adjustment strategy based on the cooling capacity adjustment condition matching the first cooling status information and the cooling capacity adjustment condition satisfied by the server; the control device determines a corresponding cooling capacity adjustment instruction based on the cooling capacity adjustment strategy, the server status information, and the first cooling status information. For example, the cooling capacity adjustment strategy corresponding to the cooling capacity adjustment condition matching the first cooling status information includes cooling capacity adjustment instructions matched at different ambient temperatures of the cabinet corresponding to the first cooling device (e.g., different fan speeds or water flow rates of the cooling device corresponding to different ambient temperatures). Here, the methods for determining the cooling capacity adjustment conditions satisfied by the corresponding server, determining the cooling capacity adjustment strategy based on the cooling capacity adjustment conditions, and determining the corresponding cooling capacity adjustment command based on the cooling capacity adjustment strategy are the same as or similar to the method by which the control device determines the corresponding cooling capacity adjustment command based on the server status information corresponding to the at least one target server, and therefore will not be repeated here, but are included by reference. In some embodiments, if there are no cooling capacity adjustment conditions matching the first cooling status information, the control device directly determines the corresponding cooling capacity adjustment command based on the server status information. This determination method is the same as or similar to the method in step S12 above, and therefore will not be repeated here, but is included by reference.

[0056] In some embodiments, the method further includes step S18 (not shown), whereby the coolant distribution device acquires second cooling status information of the second refrigeration equipment corresponding to the coolant distribution device; the coolant distribution device performs a second cooling capacity adjustment operation on the second refrigeration equipment based on the second cooling status information. For example, the coolant distribution device may also directly acquire the second cooling status information of each second refrigeration equipment under its management. The second cooling status information includes, but is not limited to, the ambient temperature information of the cabinet corresponding to the second refrigeration equipment. If the second cooling status information shows that the ambient temperature of the cabinet corresponding to the second refrigeration equipment exceeds the ambient temperature range, cooling capacity adjustment is required, and the coolant distribution device can control the second refrigeration equipment to perform a second cooling capacity adjustment operation based on the ambient temperature of the cabinet. For example, if the ambient temperature of the cabinet is too high, the second refrigeration equipment can be controlled to increase the fan speed or water flow rate, etc.; if the ambient temperature of the cabinet is too low, the second refrigeration equipment can be controlled to decrease the fan speed or water flow rate, etc.
