[0042] The core of the present invention is to provide a server fan control method, controller, computer program product and medium, which can ensure safe and stable heat dissipation of the server.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Please refer to Figure 1 , Figure 1 A flow chart of a server fan control method provided by an embodiment of the present invention, the method is applied to a first operating system in a management controller, the management controller adopts a trusted area architecture, the first operating system is located in a secure world under the trusted area architecture, and the first operating system is integrated with a server fan control script; comprising:

[0045] S101: Run the server fan control script to obtain the temperature value collected by the temperature sensor in the server;

[0046] S102: According to the temperature value collected by the temperature sensor, the server fan is regulated through the target bus.

[0047] The executor of the server fan control method in this embodiment is the first operating system in the management controller. Among them, the management controller adopts the trustzone architecture. The trustzone architecture divides the resources of the entire management controller into two worlds: a secure world and a non-secure world, namely, the ordinary world. At the hardware level, the secure world and the ordinary world have their own independent operating environments, including independent instruction set execution spaces, memory mappings, etc. The secure world is isolated from the ordinary world, and the ordinary world cannot directly access the resources of the secure world. The first operating system is located in the secure world, and the first operating system is integrated with a server fan control script and has access rights to secure hardware resources. Secure hardware resources are hardware resources that are limited to access by the first operating system. The target bus is a bus used for server fan control and belongs to secure hardware resources.

[0048] The management controller can be BMC, remote controller ILO (Integrated Lights-Out), remote controller IDRAC (Integrated Dell Remote Access Controller), etc. Take the management controller as BMC as an example, refer to Figure 2 As shown in FIG. 1 , the resources of the BMC are divided into the secure world and the normal world. The BMC OS (Operating System, operating system) is located in the normal world, and the first operating system is located in the secure world.

[0049] When the BMC starts, the bootrom runs to divide and configure the hardware resources into secure hardware resources and non-secure hardware resources, and starts the first operating system in the secure world and the BMC OS in the normal world. Non-secure hardware resources are hardware resources that can be accessed by both the first operating system and the operating system in the normal world. The first operating system can access all hardware resources, while the BMC OS is limited to accessing non-secure hardware resources. During the operation of the management controller, the first operating system is responsible for the fan control of the server. The first operating system obtains the temperature value collected by the temperature sensor in the server, and controls the server fan through the target bus according to the temperature value collected by the temperature sensor to achieve heat dissipation control. The target bus can be an I2C (Inter-Integrated Circuit) bus.

[0050] In some embodiments, obtaining a temperature value collected by a temperature sensor includes:

[0051] Read the temperature values ​​collected by the first temperature sensor and the second temperature sensor; the first temperature sensor is a temperature sensor accessible to the first operating system, and the second temperature sensor is a temperature sensor accessible to both the first operating system and the second operating system; the second operating system is located in the ordinary world under the trusted area architecture;

[0052] The temperature value collected by the second type of temperature sensor and the temperature value collected by the third type of temperature sensor transmitted by the second operating system are received; the third type of temperature sensor is a temperature sensor accessible to the second operating system.

[0053] In some embodiments, the first type of temperature sensor includes a temperature sensor for collecting the temperature of a target core component in the server.

[0054] For example, the first type of temperature sensor includes a temperature sensor for collecting the temperature of a CPU (Central Processing Unit), etc. After the server is started, the first type of temperature sensor can be bound as a secure hardware resource, and only the first operating system can access the first type of temperature sensor.

[0055] The second type of temperature sensor is a non-secure hardware resource. Both the first operating system and the second operating system can access it. The second type of temperature sensor may include an outlet / inlet temperature sensor, etc.

[0056] The third type of temperature sensor is a non-secure hardware resource that can be accessed by the second operating system. The first operating system does not set a function to access the third type of temperature sensor, so the first operating system cannot access the third type of temperature sensor. For example, the third type of temperature sensor includes a temperature sensor that collects the temperature of a RAID (Redundant Arrays of Independent Disks) card and a temperature of a network card.

[0057] After the server is started, the first operating system runs the server fan control script, starts the heat dissipation process, and reads the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor. After the server is started, the BMC OS, i.e., the second operating system, starts the heat dissipation-related process, and reads the temperature value collected by the second temperature sensor and the temperature value collected by the third temperature sensor. For example, the second operating system obtains the temperature value of the RAID card, network card, etc. through standard protocols such as MCTP (Management Component Transport Protocol), and obtains the temperature value of the outlet / inlet temperature sensor through the I2C bus. The second operating system transmits the temperature value collected by the second temperature sensor and the temperature value collected by the third temperature sensor to the first operating system so that the first operating system can perform server fan control. Among them, the heat dissipation-related process in the second operating system only has the function of reading the sensor temperature, but does not have the function of controlling the fan.

[0058] The first operating system reads the temperature values ​​collected by some temperature sensors, and the second operating system reads the temperature values ​​collected by other temperature sensors and transmits the read temperature values ​​to the first operating system. This can make the first operating system lightweight. Under the premise of ensuring the basic functions of the first operating system, the first operating system can minimize the occupation of hardware resources, remove complex system characteristics, and make the first operating system respond faster.

[0059] In some embodiments, receiving the temperature value collected by the second type of temperature sensor and the temperature value collected by the third type of temperature sensor transmitted by the second operating system includes:

[0060] The temperature value collected by the second type of temperature sensor and the temperature value collected by the third type of temperature sensor are received and transmitted by the second operating system through the trusted firmware.

[0061] The heat dissipation-related process CA (Communication Agent) of the second operating system obtains the temperature values ​​collected by the second type of temperature sensor and the temperature values ​​collected by the third type of temperature sensor. The heat dissipation-related process accesses the Linux kernel, calls the kernel driver, and writes the temperature and other data into the driver (TeeDriver) that interacts with the kernel and the first operating system. Tee Driver works in privileged mode and can pass temperature and other data to ATF (ARM Trusted Firmware) by calling SMC commands. ATF has a Secure monitor function (specially used to monitor SMC commands transmitted from the ordinary world) to capture the transmitted commands and data, and further pass them to the kernel of the first operating system. The kernel of the first operating system parses the commands and data transmitted by ATF, finds the TA (TrustedApplication) that parses the data, and completes the data transmission.

[0062] In some embodiments, according to the temperature value collected by the temperature sensor, regulating the server fan through the target bus includes:

[0063] judging whether the temperature value transmitted by the second operating system is credible according to the temperature value collected by the second temperature sensor read by the first operating system itself and the temperature value collected by the second temperature sensor transmitted by the second operating system;

[0064] If it is credible, the server fan is regulated through the target bus according to the temperature value collected by the first temperature sensor, the temperature value collected by the second temperature sensor, and the temperature value collected by the third temperature sensor;

[0065] If it is not credible, the server fan is regulated through the target bus according to the temperature value collected by the first type of temperature sensor and the temperature value collected by the second type of temperature sensor read by the first operating system.

[0066] The first operating system receives the temperature value collected by the second type of temperature sensor and the temperature value collected by the third type of temperature sensor and transmitted by the second operating system, and determines whether the temperature value transmitted by the second operating system is credible based on the temperature value collected by the second type of temperature sensor read by the first operating system itself and the temperature value collected by the second type of temperature sensor read by the second operating system.

[0067] If it is credible, the first operating system regulates the server fan according to the temperature value collected by the first temperature sensor, the temperature value collected by the second temperature sensor, and the temperature value collected by the third temperature sensor. If it is not credible, the first operating system regulates the server fan according to the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor read by the first operating system itself, while ignoring the temperature value transmitted by the second operating system. In this way, the influence of unreliable temperature values ​​on the server fan regulation can be avoided, and the accuracy and reliability of the server fan regulation can be guaranteed.

[0068] In some embodiments, judging whether the temperature value transmitted by the second operating system is credible according to the temperature value collected by the second temperature sensor read by the first operating system itself and the temperature value collected by the second temperature sensor transmitted by the second operating system includes:

[0069] comparing the temperature value collected by the second type of temperature sensor read by the first operating system itself with the temperature value collected by the second type of temperature sensor transmitted by the second operating system;

[0070] If the temperature value collected by the second type temperature sensor read by the first operating system itself is consistent with the temperature value collected by the second type temperature sensor transmitted by the second operating system, then the temperature value transmitted by the second operating system is credible;

[0071] If the temperature value collected by the second type temperature sensor read by the first operating system itself is inconsistent with the temperature value collected by the second type temperature sensor transmitted by the second operating system, the temperature value transmitted by the second operating system is unreliable.

[0072] The first operating system compares the temperature value collected by the second type temperature sensor read by the first operating system itself with the temperature value collected by the second type temperature sensor read by the second operating system.

[0073] If the temperature value collected by the second type of temperature sensor read by the first operating system itself is consistent with the temperature value collected by the second type of temperature sensor read by the second operating system, then the temperature value transmitted by the second operating system is determined to be credible; if the temperature value collected by the second type of temperature sensor read by the first operating system itself is inconsistent with the temperature value collected by the second type of temperature sensor read by the second operating system, then it is determined that the temperature value transmitted by the second operating system is suspected of being modified and the temperature value transmitted by the second operating system is unreliable.

[0074] Among them, if the temperature value collected by the second type of temperature sensor read by the first operating system itself is equal to the temperature value collected by the second type of temperature sensor read by the second operating system, or the deviation between the temperature value collected by the second type of temperature sensor read by the first operating system itself and the temperature value collected by the second type of temperature sensor read by the second operating system is within an allowable range, it can be considered that the temperature value collected by the second type of temperature sensor read by the first operating system itself is consistent with the temperature value collected by the second type of temperature sensor read by the second operating system.

[0075] If the temperature value collected by the second type of temperature sensor read by the first operating system itself is consistent with the temperature value collected by the second type of temperature sensor read by the second operating system, the first operating system regulates the server fan according to the temperature value collected by the first type of temperature sensor, the temperature value collected by the second type of temperature sensor, and the temperature value collected by the third type of temperature sensor. If the temperature value collected by the second type of temperature sensor read by the first operating system itself is inconsistent with the temperature value collected by the second type of temperature sensor read by the second operating system, the first operating system regulates the server fan according to the temperature value collected by the first type of temperature sensor and the temperature value collected by the second type of temperature sensor read by the first operating system itself, while ignoring the temperature value transmitted by the second operating system.

[0076] In some embodiments, obtaining a temperature value collected by a temperature sensor includes:

[0077] The temperature values ​​collected by all temperature sensors in the server are read; the first operating system can access all temperature sensors in the server.

[0078] In some embodiments, according to the temperature value collected by the temperature sensor, regulating the server fan through the target bus includes:

[0079] The server fans are regulated through the target bus according to the temperature values ​​collected by all temperature sensors read by the first operating system itself.

[0080] In this embodiment, the first operating system has the ability to access all temperature sensors in the server and can read the temperature values ​​collected by all temperature sensors in the server. On the basis of the first operating system itself reading the temperature values ​​collected by all temperature sensors, the first operating system directly controls the server fans according to the temperature values ​​read by itself. The first operating system itself reads the temperature values ​​collected by all temperature sensors, without the need for the second operating system to read and transmit the temperature values ​​collected by the temperature sensors, which can further improve the isolation between the first operating system and the second operating system, making the server fan control safer and more reliable.

[0081] In some embodiments, the first operating system runs on a single processing core and the second operating system runs on multiple processing cores.

[0082] Based on the lightweight design of the first operating system, the first operating system can run on a single independent processing core. The second operating system retains other functions besides server fan control, for example, retains device information management, remote control management and other functions. The second operating system can run on multiple processing cores.

[0083] In some embodiments, it also includes:

[0084] Counting the number of times that the temperature value transmitted by the second operating system is unreliable;

[0085] Determining whether the number of times that the temperature value transmitted by the second operating system is unreliable reaches a preset threshold;

[0086] If it is reached, an alarm will be issued.

[0087] The first operating system can count the number of times the temperature value transmitted by the second operating system is unreliable, and determine whether the number of times the temperature value transmitted by the second operating system is unreliable reaches a preset threshold. If it reaches, it indicates that the temperature value obtained by the second operating system has been modified multiple times, and there is a greater security risk in the second operating system, and an alarm can be issued at this time. If it does not reach, only the number of times the temperature value transmitted by the second operating system is unreliable can be recorded.

[0088] In some embodiments, it also includes:

[0089] If the temperature value transmitted by the second operating system is not credible, information indicating that the temperature value transmitted by the second operating system is not credible is transmitted to the second operating system.

[0090] When the first operating system determines that the temperature value transmitted by the second operating system is unreliable, it can transmit information indicating that the temperature value transmitted by the second operating system is unreliable to the second operating system, and then the second operating system can stop transmitting the temperature value to the first operating system. Since the temperature value transmitted by the second operating system is unreliable, it indicates that the temperature value obtained by the second operating system is suspected of being maliciously modified, and the second operating system has a security risk. Therefore, after the second operating system receives the information transmitted by the first operating system indicating that the temperature value transmitted by the second operating system is unreliable, the second operating system can also issue an alarm prompt.

[0091] In summary, the server fan control method provided by the present invention integrates the server fan control function in the first operating system in the secure world under the trusted area architecture, that is, the trustzone architecture, and the first operating system in the secure world is responsible for controlling the server fan, and the first operating system in the secure world is not easily damaged by humans. The isolation between the ordinary world and the secure world under the trustzone architecture is relatively high, and the operating system in the ordinary world has no authority to intervene in the server fan control function of the first operating system in the secure world.
