Energy-saving method applied to machine room, apparatus, and system

An energy-saving method applied to a machine room, wherein the machine room comprises a plurality of cabinets and at least one temperature regulating device, each cabinet comprises at least one server, each server is configured to provide a computing resource, and each temperature regulating device is configured to regulate a temperature of the machine room;

• the machine room is further provided with a facility management device, and the facility management device is configured to manage the computing resource and the temperature regulating device that are of the machine room;
• and the method comprises:
• obtaining cooling capacity conduction relationship information of the machine room and computing resource status information of the machine room, wherein between each cabinet of the plurality of cabinets and each temperature regulating device of the at least one temperature regulating device, the cooling capacity conduction relationship information of the machine room includes a value indicating a capability of the cabinet to absorb a cooling capacity of the temperature regulating device;
• and
• triggering, based on the cooling capacity conduction relationship information and the computing resource status information, the facility management device to execute a computing resource management instruction set to minimize a total power of the machine room while meeting a service requirement, wherein the cooling capacity conduction relationship information is for determining a capability of each cabinet in the machine room to absorb a cooling capacity of each temperature regulating device in the machine room, and the computing resource status information is for determining a running location and a running status that are of the computing resource comprised in the machine room.
