The client demands the server more and more in terms of performance, and the stability demands the same more and more. In practical applications, the BMC chip may be subjected to various disturbances, such as electromagnetic radiation, which may cause the BMC chip to fail. When the BMC chip fails, the fan is out of control, and a large amount of special chips integrated in the server generate a large amount of heat, if the heat is dissipated in time, the whole server has a risk of abnormal work. If the state before the BMC chip fails is not stored, the opportunity of analyzing the failure reason of the BMC chip is lost. Meanwhile, the BMC chip is invalid, and alarm information cannot be sent to a control room.
