Abstract:
1. A method for protecting a server against fan failure, the server comprising a storage unit and a plurality of fans, the method comprising: detecting a rotation speed of each of the fans and timing a continuous working time period of each of the fans; comparing the detected rotation speed and the timed continuous working time period of each fan with a corresponding predefined rotation speed and a corresponding predefined continuous working time period stored in the storage unit, generating results of the comparisons, and determining whether any of the results for any one or more of the fans fall into one or more predefined failure conditions for the fans stored in the storage unit; obtaining a countdown time period stored in the storage unit and starting a countdown based on the countdown time period when any of the results for any one or more of the fans fall into one or more predefined failure conditions for the fans; and shutting down the server when the countdown reaches zero.
