Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a control method applied to a centralized management controller, including:
and 102, when the temperature of the external plug-in display card is overheated, sending a frequency reduction signal to a processor connected with the external plug-in display card so as to reduce the working frequency of the processor.
In the above embodiment of the present invention, the centralized management controller collects the temperature information of the external plug-in graphics card, and determines whether the external plug-in graphics card is overheated according to the collected temperature information, and when it is determined that the external plug-in graphics card is overheated, the centralized management controller may send a down-conversion signal to the processor connected to the external plug-in graphics card, so as to reduce the operating frequency of the processor; correspondingly, when the working frequency of the processor connected with the externally-inserted display card is reduced, the image data to be processed sent to the externally-inserted display card by the processor is reduced, so that the data calculation amount of the externally-inserted display card is reduced, and the damage of the externally-inserted display card due to overhigh temperature can be prevented.
Because the standard bus interface slot arranged on the mainboard is usually reserved with corresponding custom connection pins, part of the external plug-in display card is also correspondingly reserved with custom connection pins, the heating part of the external plug-in display card is mainly concentrated on the image processing chip, and the external plug-in display card can monitor the temperature parameter of the image processing chip through corresponding monitoring logic to determine whether the external plug-in display card generates temperature overheating, in one embodiment of the invention, before the step of collecting the temperature information of the external plug-in display card and determining whether the external plug-in display card generates temperature overheating according to the temperature information, the method further comprises the following steps:
presetting a custom pin of an external plug-in display card so as to provide a preset level signal when the external plug-in display card is overheated;
then, the acquiring temperature information of the extrapolated display card and determining whether the extrapolated display card is overheated according to the temperature information includes:
collecting a sampling level signal provided by a custom pin of the external plug-in display card;
and when the sampling level signal is the same as the preset level signal, determining that the temperature of the display card to be controlled is overheated.
For example, the external graphics card itself may monitor the temperature parameter of the image processing chip through the corresponding monitoring logic, when the temperature parameter is greater than the corresponding temperature value (e.g., 105 ℃), it indicates that the temperature of the external graphics card is too hot, and by setting the custom pin of the external graphics card, the custom pin of the external graphics card provides the preset level when determining that the temperature of the external graphics card is too hot (e.g., the external graphics card provides a high level when the temperature is too hot, and the external graphics card provides a low level when the temperature is not too hot), and the centralized manager may collect the sampling level signal provided by the custom pin of the external graphics card, and determine that the temperature of the external graphics card is too hot when the sampling level signal is the same as the preset level signal.
Specifically, in an embodiment of the present invention, the setting a custom pin of an external graphics card, so that the custom pin provides a preset level signal when the external graphics card is overheated, includes:
and setting a self-defined pin corresponding to the B12 pin of the standard bus interface slot in the external plug-in display card, so that the self-defined pin provides a preset level signal when the temperature of the external plug-in display card is not less than 105 ℃.
Accordingly, when the external graphics card cannot monitor the temperature parameter of the image processing chip thereof to determine whether the external graphics card is overheated, in an embodiment of the present invention, the acquiring the temperature information of the external graphics card and determining whether the external graphics card is overheated according to the temperature information includes:
collecting sampling temperature parameters of an image processing chip of the externally-inserted display card;
and when the sampling temperature parameter is greater than a preset temperature threshold value, determining that the temperature of the extrapolation display card is overheated.
For example, the centralized management controller may collect temperature parameters of an image processing chip of the external graphics card through a corresponding temperature sensor, and determine that the external graphics card is overheated when the collected temperature parameters are greater than a preset temperature threshold (e.g., 105 ℃).
In order to more clearly illustrate the technical solutions and advantages of the present invention, the example that the add-in graphics card itself can determine whether the temperature of the add-in graphics card is too high for the temperature parameter of the image processing chip of the add-in graphics card is taken as an example, the example that the centralized management controller controls the operating frequency of the correspondingly connected processor to prevent the add-in graphics card from being damaged due to too high temperature is taken as an example, the method specifically includes the following steps:
For example, the extrapolation display card can monitor the temperature parameter of the image processing chip, and the corresponding monitoring logic is set, so that the extrapolation display card provides a high-level signal when the temperature parameter of the image processing chip is not less than 105 ℃ under monitoring.
And 202, inserting the set external plug-in card to a standard bus interface of the server to be expanded.
Here, the sampling level signal of the B12 pin in the standard bus interface slot is the sampling level signal provided by a corresponding one of the custom pins in the extrapolated graphics card.
For example, when the frequency class of the processor includes 2.4 hz and 1.7 hz, if the operating frequency of the current processor is 2.4 hz, and the external graphics card is overheated, that is, when the processor receives the down-conversion signal sent by the centralized management controller, the operating frequency of the current processor can be reduced from 2.4 hz to 1.7 hz, and when the operating frequency of the processor is 2.4 hz, the data volume of the image data to be processed sent to the correspondingly connected external graphics card is relatively large, and when the operating frequency is reduced to 1.7 hz, the image data to be processed sent by the processor to the external graphics card is relatively small, that is, the number of the image data to be processed sent by the processor to the external graphics card is reduced, the data operation volume of the external graphics card is reduced, and the external graphics card does not continuously perform a large number of data operations, thereby avoiding damage due to overhigh temperature.
Correspondingly, the embodiment of the invention realizes the adjustment of the data operation amount of the externally-inserted display card by controlling the working frequency of the processor connected with the externally-inserted display card, thereby realizing the prevention of the damage of the externally-inserted display card caused by overhigh temperature, further improving the stability of the server plugged with the externally-inserted display card and preventing the downtime of the server caused by the damage of the externally-inserted display card.
