Embodiment
Describe the present invention below with reference to embodiment shown in the drawings.But these embodiments do not limit the present invention, the structure that those of ordinary skill in the art makes according to these embodiments, method or conversion functionally are all included in protection scope of the present invention.
Shown in please refer to the drawing 1, Fig. 1 is the control method for fan of server of the present invention and the hardware environment Organization Chart of application of installation.In the present embodiment; the control method for fan of this server is applied in has CPU (CentralProcessing Unit; central processing unit) and BMC (Baseboard Management Controller; baseboard management controller) server in; except the CPU shown in figure, BMC, internal memory and NVRAM (Non-Volatile Random Access Memory; nonvolatile memory) outside, in embodiment, the equipment at device place can also comprise other hardware usually.Wherein, server of the present invention comprises CPU and BMC, this CPU with BMC is communicated by system interface (System Interface), can run a program of debugging for fan speed-regulating on CUP, in real time by the Refresh Data of fan speed-regulating strategy to BMC side.In detail, this CPU, for reading the fan-status data of BMC, according to the original fan speed-regulating strategy of described fan-status data point reuse BMC, obtains and upgrades fan speed-regulating strategy, and described renewal fan speed-regulating strategy is sent to described BMC; The described renewal fan speed-regulating strategy that this BMC sends for receiving described CPU, come into force to make described renewal fan speed-regulating strategy by restarting speed-regulating control module, particularly, in the present embodiment, this speed-regulating control module is that virtual functions is restarted, and namely corresponding software code is restarted.
Wherein, as shown in Figure 2, the control method for fan of server of the present invention is applied in the CPU of server, and this server can also comprise BMC, and further, BMC comprises speed-regulating control module, and particularly, the method comprises:
Step 201, acquisition fan-status data.
In the present embodiment, by the acquisition fan-status data that the program of running a fan speed-regulating on CPU is real-time, in detail, these fan-status data can comprise fan speed data and to should the warming data etc. of environment residing for fan.Meanwhile, the fan speed-regulating strategy of all right current BMC of Real-time Obtaining of this program, i.e. original fan speed-regulating strategy.
Step 203, original fan speed-regulating strategy according to fan-status data point reuse BMC, obtain and upgrade fan speed-regulating strategy.
In the process, the fan-status data that can obtain according to CPU, by revising original fan speed-regulating strategy, thus make this CPU obtain renewal fan speed-regulating strategy.Such as, in the server, corresponding to the fan of a certain control module, this control module institute's power consumption that produces when running multiple execution instruction is larger, therefore produced heat is also more, now CPU is by the temperature of environment residing for the original fan speed-regulating strategy of this fan of Real-time Obtaining and fan, and the renewal fan speed-regulating strategy obtaining amendment in time accelerates to rotate to make fan, thus dispels the heat for this control module; The power consumption produced when this control module is run less execution instruction or do not performed instruction is less, therefore produced heat is also less, temperature environment residing for fan is lower, now CPU obtains the renewal fan speed-regulating strategy of amendment in time to make fan underdrive, thus realizes while meeting the radiating requirements of corresponding element device reducing power consumption.
Step 205, to send to BMC and upgrade fan speed-regulating strategy, after restarting speed-regulating control module to make BMC, make renewal fan speed-regulating strategy come into force.
Particularly, renewal fan speed-regulating strategy is sent to BMC by CUP, and BMC, by restarting speed-regulating control module, reads after restarting and upgrades fan speed-regulating module, and this renewal fan speed-regulating strategy is come into force.
Further, method of the present disclosure can also comprise, and the enable mark for upgrading the configuration of fan speed-regulating strategy is sent to BMC, with make BMC enable be designated enable time, run and upgrade fan speed-regulating strategy.CPU by by configuration enable mark send to BMC, this BMC enable be designated enable time, run this renewal fan speed-regulating strategy.In an embodiment of the present invention, this enable mark can be sent to BMC for reading or also can being sent to BMC for reading after transmission upgrades fan speed-regulating strategy simultaneously when sending and upgrading fan speed-regulating strategy.
