Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a heat dissipation management method, apparatus, device and machine-readable storage medium. Background Technology

[0002] With the development of server technology, more and more cards are still running in auxiliary power mode. Taking some common OCP NIC cards as examples, their power consumption is still around 10W in auxiliary power mode, which poses a serious challenge to heat dissipation control in auxiliary power mode.

[0003] The BMC identifies the PCIe card model by relying on the BIOS to read four IDs (vendorID, deviceID, subvendorID, and subdeviceID) from the PCIe domain and then pass this information to the BMC. Identifying the PCIe card model based on these four IDs is a common solution for PCIe card identification. In auxiliary power mode, since the BIOS is not enabled, the BMC cannot obtain the four IDs for model identification. Furthermore, each card has different thermal characteristics; only after identifying the specific card model can precise heat dissipation control be implemented. Therefore, in auxiliary power mode, precise heat dissipation based on the card model is not possible. Summary of the Invention

[0022] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to any and all possible combinations comprising one or more of the associated listed items.

[0023] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" may also be interpreted as "when," "when," or "in response to a determination."

[0024] In one approach, to cool down the OCP NIC card, the NCSI channel can be selected in auxiliary power mode, and the card model and temperature can be obtained through the NCSI command for refined cooling. However, the NCSI command is only applicable to NIC cards and is not universal to PCIe cards. If it is necessary to obtain the temperature of multiple cards, it is necessary to ensure that these NIC cards can be selected through the NCSI channel on the hardware path. In addition, switching the NCSI path requires re-initializing the network, which will affect the out-of-band network connectivity and cause temporary disconnections.

[0025] In view of this, the present disclosure provides a heat dissipation management method, apparatus, electronic device, and machine-readable storage medium to improve the problem of inability to achieve precise heat dissipation under the aforementioned auxiliary power state.

[0026] Specifically, the technical solution is described below.

[0027] In one embodiment, this disclosure provides a thermal management method applied to a BMC management device. The method includes: in response to BMC management device initialization, configuring the PCIe card list to an invalid state, the PCIe card list being used to record card information; after BIOS startup, updating the PCIe card list according to the card information of the PCIe cards identified and transmitted by the BIOS, and configuring the PCIe card list to an valid state; in response to the valid state of the PCIe card list, obtaining the core temperature of the PCIe card according to the information recorded in the PCIe card list, and adjusting the heat dissipation device according to the core temperature.

[0028] Specifically, such as Figure 1 This includes the following steps:

[0029] Step S11: In response to the initialization of the BMC management device, the PCIE card list is configured to be invalid. The PCIE card list is used to record card information.

[0030] Step S12: After the BIOS starts, update the PCIE card list according to the PCIE card information identified and transmitted by the BIOS, and configure the PCIE card list to be valid.

[0031] Step S13: In response to the valid status of the PCIe card list, obtain the core temperature of the PCIe card according to the PCIe card list record information, and adjust the heat dissipation device according to the core temperature.

[0032] The system records the latest PCIe card information obtained each time the BIOS is re-enabled into the corresponding PCIe card list. When the PCIe card list is valid, the system obtains the core temperature of the PCIe card based on the recorded card information and adjusts the cooling accordingly. Even after the BIOS is turned off in the subsequent auxiliary power state, it can still maintain precise cooling.

[0033] In one implementation, the step of configuring the PCIe card list to an invalid state in response to the initialization of the BMC management device, wherein the PCIe card list is used to record card information, includes: in response to the invalid state of the PCIe card list, obtaining the ambient temperature of the PCIe card, and adjusting the heat dissipation device according to the ambient temperature.

[0034] In one implementation, the step of updating the PCIe card list and configuring the PCIe card list to an active state based on the PCIe card information identified and transmitted by the BIOS after BIOS startup includes: configuring the PCIe card list to an invalid state in response to a PCIe card insertion / removal event.

[0035] In one embodiment, the step of responding to the valid state of the PCIe card list, obtaining the core temperature of the PCIe card based on the PCIe card list record information, and adjusting the heat dissipation device based on the core temperature includes: responding to the valid state of the PCIe card list, obtaining the core temperature of the PCIe card and a temperature control strategy based on the PCIe card list record information, and adjusting the heat dissipation device based on the core temperature and the temperature control strategy.

[0036] In one implementation, heat dissipation control under auxiliary power conditions is performed based on the most recently transmitted valid PCIe card information from the BIOS.

[0037] After AC power is applied, BMC starts up and initializes the heat dissipation module. It sets the PCIe card list information to an invalid state by default to avoid the solution failing due to discrepancies between the last remaining card information and the current situation.

[0038] After the BIOS boots up, it transmits the board information of the identified PCIe cards to the BMC. The BMC records the PCIe card information, such as model information, into the PCIe card list and simultaneously sets the PCIe card list to an active state. When the PCIe card list is active, the BMC uses the recorded board information to obtain the core temperature of the card and adjusts the cooling speed accordingly.

[0039] When the PCIe card list is invalid, the BMC adjusts the cooling speed based on the ambient temperature of the PCIe cards. After a PCIe card hot-plugging event occurs, the BMC invalidates the PCIe card list.

[0040] In one embodiment, this disclosure also provides a heat dissipation management device, such as... Figure 2 This device, applied to a BMC management device, includes: a startup module 21, configured to invalidate the PCIE card list in response to BMC management device initialization (the PCIE card list is used to record card information); a configuration module 22, configured to update the PCIE card list and configure it to valid after BIOS startup, based on the PCIE card information identified and transmitted by the BIOS; and an adjustment module 23, configured to obtain the core temperature of the PCIE card based on the information recorded in the PCIE card list, and adjust the cooling device according to the core temperature, in response to the valid state of the PCIE card list.

[0041] In one implementation, the step of configuring the PCIe card list to an invalid state in response to the initialization of the BMC management device, wherein the PCIe card list is used to record card information, includes: in response to the invalid state of the PCIe card list, obtaining the ambient temperature of the PCIe card, and adjusting the heat dissipation device according to the ambient temperature.

[0042] In one implementation, the step of updating the PCIe card list and configuring the PCIe card list to an active state based on the PCIe card information identified and transmitted by the BIOS after BIOS startup includes: configuring the PCIe card list to an invalid state in response to a PCIe card insertion / removal event.

[0043] In one embodiment, the step of responding to the valid state of the PCIe card list, obtaining the core temperature of the PCIe card based on the PCIe card list record information, and adjusting the heat dissipation device based on the core temperature includes: responding to the valid state of the PCIe card list, obtaining the core temperature of the PCIe card and a temperature control strategy based on the PCIe card list record information, and adjusting the heat dissipation device based on the core temperature and the temperature control strategy.
