Abstract

The embodiment of the invention discloses a double-controller signal control device and method. A detection part receives a first level signal sent by a first controller and receives a second level signal sent by a second controller. A selection signal corresponding to the main controller is sent to the selector according to the level types corresponding to the first level signal and the second level signal. And the selector opens a corresponding data channel according to the selection signal so as to transmit the control signal sent by the main controller to the terminal equipment. Accordingto the technical scheme, the detection part determines the control power of the two controllers according to the level signal, the determination mode completely depends on hardware, and the delay caused by software control or the influence caused by unstable software operation can be effectively reduced. And moreover, the selector opens the corresponding data channel according to the selection signal, so that the competition danger situation is avoided. Through the cooperation of the detection part and the selector, the orderly management between the double controllers is realized.

Description

technical field [0001] The invention relates to the technical field of storage servers, in particular to a dual-controller signal control device and method. Background technique [0002] In storage server design, in order to ensure the stability of server operation, a dual-controller design is usually adopted, that is, there are two controllers that can be used to access terminal devices, such as hard disks, fans, and power supplies. [0003] In the prior art, in order to ensure the orderly operation of the two controllers, there are mainly two processing methods for the controllers. One way of doing this is to simply connect the signals via wire-ANDs. Considering that in the actual transmission process, due to the different transmission paths, the dual control signal lines will lead to competition risks. For periodic signals, such as pulse width modulation (Pulse Width Modulation, PWM) signal used to control the fan speed, fan speed conversion (tachometer, TACH) signal, a...
