Problems solved by technology
Moreover, due to the uneven air pressure of the system, the wind pressure at the position directly facing the ordinary fan increases, and the position directly facing the faulty fan may be affected by the wind pressure and the air volume will decrease instead, affecting the heat dissipation of the system at this time.

The present invention provides a speed regulation method, system, terminal and storage medium for dealing with a fan rotor failure, including: collecting the pre-failure rotational speed of a fan with a rotor fault; calculating the fan according to the pre-failure rotational speed and a pre-stored system flow resistance characteristic function The air pressure before the failure and the air volume before the failure; input the air volume before the failure and the wind pressure before the failure into the single rotor flow resistance function, and obtain the single rotor speed of the fan under the same air volume and pressure; adjust the speed of the fan with the rotor failure to the single rotor speed of the fan. According to the current operating speed of the normal fan, the fan flow resistance characteristics, and the system flow resistance characteristics, the invention calculates and adjusts the speed of the fan rotor in normal operation, and keeps the speed of other normal fans unchanged, and compensates the wind flow and pressure loss of the faulty rotor to realize The system has uniform air pressure and air flow, optimal cooling capacity, and the lowest fan power consumption and lowest noise.
Description
technical field [0001] The invention relates to the technical field of server fan control, and specifically relates to a speed control method, system, terminal and storage medium for dealing with fan rotor failure. Background technique [0002] Server fans generally use N+1 redundant backup, and each fan usually uses two rotors as redundant backup. When a rotor of a fan in the system fails, the system needs to be regulated so that the system can still dissipate heat normally. At this time, the maximum temperature specification supported by the system will be reduced by 5 degrees. [0003] In most cases, server system fans will not work at full speed, and generally work at reduced speed. Take the common 2U server system using four dual-rotor fans as an example. When a single rotor of a fan fails, the current strategy is to bring all fans to full speed. At this time, the fan works in the maximum mode, and the fan system consumes the highest power consumption and the highest...
