Problems solved by technology

However, when the storage server is in the power-on state and the storage server is in the power-off state, the BMC of the dual-control controller does not output the PWM signal for controlling the fan, but the CPLD corresponding to the dual-control controller controls the fan. When the storage server is not in the backup power state, the CPLD corresponding to the dual-control storage server also controls the fans. In both cases, the CPLDs of the two controllers will output control signals to the fans. Because the CPLDs of the two controllers There will be a phase difference between the output control signals, which will lead to uneven speed of the fan and cause fan failure.

Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] The embodiment of the present invention discloses a fan control method, device, device, and computer-readable storage medium based on a dual-control storage server, which avoids the existence of CPLD output by two controllers when the storage server is in the power-on state and power-off state When the phase difference control signal controls the rotation of the fan, the problem of fan failure caused by uneven rotation speed.

[0053] See figure 1 , f...

Abstract

The invention discloses a fan control method based on a dual-control storage server. After detecting that the storage server is in a standby power state, a state signal of the storage server is obtained; if the state signal is a non-operating state signal, the storage server is in a startup state or a shutdown state; in this case, in order to avoid the situation of uneven fan rotation speed causedby control signals sent to a fan by CPLDs corresponding to dual-control controllers, a first target CPLD is selected first, and then the fan is controlled by the selected first target CPLD. In this way, only the selected first target CPLD is required to control the fan, and the other CPLD is in an uncontrolled state at this time, so that the first target CPLD is prevented from interfering the control of the fan. In addition, the invention also discloses a fan control device and equipment based on the dual-control storage server, and a storage medium, which have the effects above.

Description

technical field [0001] The present invention relates to the server field, in particular to a fan control method, device, equipment and computer-readable storage medium based on a dual-control storage server. Background technique [0002] In order to ensure highly reliable control of the storage server, a dual-controller scheme is generally used to control the fans. Generally, the storage server is in the running state after it is normally powered on (backup power state), and when the two controllers are running normally, there will be data communication between the two controllers, and the BMC as the main control controller will turn the fan The PWM signal output by the control strategy is sent to the fan. At this time, the BMC as the auxiliary control controller does not output the PWM signal. However, when the storage server is in the power-on state and the storage server is in the power-off state, the BMC of the dual-control controller does not output the PWM signal for ...
