Abstract:
A rack fan speed regulation method based on a fan table provided in a node BMC is provided, which includes: providing a fan table reflecting a rack fan speed regulation policy in a BMC of each node server; acquiring, by the node BMC, a parameter reflecting a heat dissipation condition of a node motherboard; and acquiring, by the node BMC based on the speed regulation policy, a fan rotation speed corresponding to the parameter rapidly. With the rack fan speed regulation method, the node BMC can rapidly obtain parameters reflecting a heat dissipation condition of a node motherboard, and rapidly obtain a corresponding fan rotation speed based on the speed regulation policy. In this case, heat dissipation of the node can be controlled effectively in a timely manner, thereby ensuring heat dissipation of the rack.

Claim (Index 2):
The rack fan speed regulation method based on a fan table provided in a node BMC according to  claim 1 , further comprising:\n 1) performing a heat dissipation test to obtain a fan table comprising different CPU temperatures and different ambient temperatures; 2) writing, based on the fan table, BMC speed regulation policy program codes, which control the node BMC to obtain, based on a CUP temperature and an intake vent temperature of the node server at which the node BMC is located, a fan duty value of a node corresponding to the node BMC, and send the fan duty value to a node mid-plane; 3) writing a node mid-plane fan control program, which controls the node mid-plane to select a maximum fan duty value from fan duty values of four nodes connected to the node mid-plane and located on a same layer as the node mid-plane, to obtain a fan duty value of the node mid-plane of the layer; and 4) writing a RMC fan control program, which controls a RMC to obtain the fan duty value of the node mid-plane of each layer from the node mid-plane, obtain a maximum fan duty value of node mid-planes in an upper half rack and a maximum fan duty value of node mid-planes in a lower half rack, and separately control a fan rotation speed of a fan window corresponding to nodes of the upper half rack and a fan rotation speed of a fan window corresponding to nodes of the lower half rack through a fan control board, to separately control fans in the upper half rack and fans in the lower half rack.
