Abstract: The present disclosure provides a fan management method and system, and a server. The method includes: monitoring working performance of each dual-motor fan in real-time; determining whether the working performance of the dual-motor fan is normal, if the working performance is normal, instructing the dual-motor fan to continue to operate with normal performance; if the working performance is not normal, instructing a single-motor fan that has no abnormality in the dual-motor fan to operate with a preset compensation strategy; the preset compensation strategy is a strategy for performing performance compensation for a single-motor fan that has no abnormality to normal performance of a dual-motor fan. The present disclosure can reduce energy consumption of the server, avoid ineffective waste, and save operating costs. The fan can be prevented from running at a high speed for a long time, and the service life of the fan can be improved.

Abstract: A method for updating a firmware of a complex programmable logic device comprises: electrically connecting a general purpose input/output pin of a baseboard management controller with a hitless enable pin of a complex programmable logic device; electrically connecting a first integrated circuit bus of the baseboard management controller with a second integrated circuit bus of the complex programmable logic device; inputting and transmitting a update command to the baseboard management controller by a local operating system; enabling the hitless enable pin by the baseboard management controller according to the update command; cleaning a first firmware in the complex programmable logic device by the baseboard management controller according to the update command; and burning a second firmware into the complex programmable logic device by the baseboard management controller according to the update command.
