[0084] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other instances obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0085] Currently, in storage systems, to monitor and dissipate heat at various temperature points, configuration files are used to pre-record each temperature point and its corresponding speed control parameters. Furthermore, different types of interface cards, such as network cards, connected to the storage system are required to operate at the same temperature points, which is detrimental to the heat dissipation of different types of interface cards. Therefore, this application provides a fan speed control scheme that can specifically address heat dissipation for different interface card devices.

[0086] See also Figure 1 As shown in the figure, this application discloses a fan speed control method, including:

[0087] S101. Obtain card information of at least one interface card plugged into at least one target slot.

[0088] In this embodiment, the storage system or server includes multiple slots, including network card slots and hard disk slots. Correspondingly, the interface card can be a network card or a hard disk, etc. In one example, obtaining the card information of at least one interface card plugged into at least one target slot includes: initializing each slot in the current device; traversing each slot using the basic input / output system of the current device to determine at least one target slot in a working state; and reading the card information of at least one interface card plugged into at least one target slot.

[0089] S102. Determine at least one temperature monitoring point corresponding to an interface card based on the card information, as well as the fan zone and speed control parameters matched to the temperature monitoring point.

[0090] It should be noted that each interface card corresponds to at least one temperature monitoring point, and each temperature monitoring point is matched with a fan zone and speed control parameters. The fan zone matched to the temperature monitoring point is used to determine: which fans are responsible for cooling that temperature monitoring point; and accordingly, the fan speed within the corresponding fan zone is calculated using the temperature value of that monitoring point. That is, a speed is calculated for each fan within the corresponding fan zone using the temperature value of that monitoring point. However, since the same fan may be assigned to different fan zones, it is necessary to wait until the temperature values ​​of all temperature monitoring points have been calculated for the fans in their respective fan zones, so that each fan corresponds to at least one speed value. Then, the maximum speed corresponding to the same fan is selected as the operating speed of that fan.

[0091] In one example, determining at least one temperature monitoring point corresponding to an interface card, and the corresponding fan partition and speed control parameters matched to that temperature monitoring point, based on card information includes: checking if a configuration file corresponding to the card information exists; if a configuration file exists, loading the configuration file and querying the temperature monitoring point, fan partition, and speed control parameters within the configuration file. If a configuration file does not exist, creating the configuration file, loading the configuration file, and querying the temperature monitoring point, fan partition, and speed control parameters within the configuration file are performed. One interface card corresponds to one configuration file.

[0092] S103. Use the temperature monitoring thread to monitor the temperature value of the temperature monitoring point.

[0093] In one example, before monitoring the temperature value of a temperature monitoring point using a temperature monitoring thread, the process includes: determining whether the temperature monitoring point is enabled; if the temperature monitoring point is enabled, then executing the step of monitoring the temperature value of the temperature monitoring point using the temperature monitoring thread; otherwise, skipping the current temperature monitoring point. Each interface card corresponds to several temperature monitoring points, and information on which temperature monitoring points are enabled and disabled is recorded and updated in real time. This information can be specifically recorded in the configuration file corresponding to each interface card.

[0094] In one example, before calculating the fan speed within the corresponding fan zone based on the temperature value and speed control parameters, the process includes: determining if the temperature value is valid; if the temperature value is valid, then calculating the fan speed within the corresponding fan zone based on the temperature value and speed control parameters; if the temperature value is invalid, then determining if a backup temperature value exists; if a backup temperature value exists, then using the backup temperature value as the temperature value, and then calculating the fan speed within the corresponding fan zone based on the temperature value and speed control parameters; if no backup temperature value exists, then determining the target speed corresponding to the invalid temperature of the temperature monitoring point. Correspondingly, whether a temperature monitoring point has a backup temperature point, and how many backup temperature points there are, are all recorded and can be updated in real time. Specifically, this information can be recorded in the configuration file corresponding to each interface card. For example, if the network card's CPU temperature fails, but the network card's optical module temperature can be collected as the CPU temperature, in this example, the optical module temperature is the backup temperature value.

[0095] S104. Calculate the fan speed in the corresponding fan zone based on the temperature value and speed regulation parameters, and select the maximum speed corresponding to the same fan as the working speed of that fan.

[0096] In this embodiment, the speed control parameters are specifically the parameters of the PID algorithm, and therefore include: proportional coefficient, integral coefficient, and derivative coefficient. In one example, calculating the fan speed in the corresponding fan zone based on the temperature value and the speed control parameters includes: obtaining the proportional coefficient, integral coefficient, and derivative coefficient from the speed control parameters; and calculating the fan speed in the corresponding fan zone using the proportional coefficient, integral coefficient, derivative coefficient, preset desired speed, and temperature value. The calculation process can be referred to related technologies and will not be elaborated here.

[0097] This embodiment also records temperature monitoring points in real time; upon detecting an update to a temperature monitoring point, the corresponding fan partition and speed control parameters are updated accordingly. Temperature monitoring point updates include adding, deleting, and modifying temperature monitoring points.

[0098] In one example, after monitoring the temperature value of the temperature monitoring point using the temperature monitoring thread, the process also includes: issuing an alarm or de-alarming for the temperature monitoring point based on the temperature value.

[0099] In one example, the method further includes: using a fan monitoring thread to obtain the fan's presence status and actual fan speed; determining the fan's health status based on the fan's presence status and actual fan speed; and issuing or de-alererating alarms for the fan based on the fan's health status.

[0100] As can be seen, this embodiment sets corresponding temperature monitoring points and their matching fan zones and speed control parameters for at least one interface card plugged into each slot. Therefore, after monitoring the temperature value of the temperature monitoring point using the temperature monitoring thread, the fan speed in the corresponding fan zone can be calculated based on the temperature value and speed control parameters, and the maximum speed corresponding to the same fan can be selected as the operating speed of that fan. Thus, this solution achieves automatic identification of interface card devices and temperature monitoring points, and automatically determines the fan zone and speed control parameters based on the identification results, thereby achieving precise fan control, improving fan maintenance efficiency and accuracy, and enabling targeted heat dissipation for different interface card devices.

[0101] See Figure 2 This paper presents a fan speed control solution, including a fan speed control module, a sensor management module, and a sensor acquisition module. For pluggable PCIe interface card devices, each temperature point has its own speed control parameters; furthermore, when the temperature sensor name at a temperature point is dynamically changed, there is no need to manually adjust the cooling configuration of the fan speed control module.

[0102] The sensor acquisition module (i.e., the interface card management module) is primarily responsible for acquiring sensor data. For pluggable PCIe interface card devices, it dynamically registers sensor information to the sensor management module. Taking an interface card as an example, it identifies the slot as in place, obtains basic PCIe device information based on the slot information, reads the device's PN information, and loads the corresponding configuration file (newly created locally) based on the PN information. The configuration file configures the interface card's sensor information, the PID speed control parameters corresponding to each sensor, and the speed control zone it belongs to. Sensors can be added or deleted according to the interface provided by the sensor module. A pre-set thermal management document records the PID speed control parameters and speed control zones corresponding to various temperature sensors. When a newly plugged-in PCIe interface card device is detected and its corresponding temperature sensors are identified, the thermal management document is consulted to find the corresponding PID speed control parameters and speed control zones for each temperature sensor.

[0103] See Figure 3 The interface card management module implements the following functions:

[0104] Step 1: Obtain the number of PCIe device slots (SLOTs) through the hardware adaptation layer and initialize all SLOTs;

[0105] Step 2: After BIOS boot is complete, iterate through all slots and obtain the interface card presence signal on the corresponding slot.

[0106] Step 3: Once the device is detected in place, obtain the basic information of the PCIe device based on the SLOT. Then, based on the VID (Vendor Identification), DID (Device Identification) used to distinguish different models of the same type of device, SVID (Subsystem Vendor Identification), and SDID (Subsystem Device Identification, which is the code for the device manufactured by the manufacturer), obtain the PN (Part Number) information of the PCIe device.

[0107] Step 4: Interface card successfully recognized; load the corresponding interface card configuration file based on the PN information.

[0108] Step 5: Obtain sensor information based on the sensor points and sensor configuration information in the configuration file. The temperature sensor information includes temperature threshold, whether it participates in heat dissipation speed regulation, heat dissipation area, and speed regulation parameters.

[0109] Step 6: Add or delete sensor information according to the interface provided by the sensor module.

[0110] The sensor management module is responsible for updating sensor management information, including processing sensor data and alarm status. When a sensor is dynamically registered, deleted, or its name is dynamically modified, the sensor management module updates the sensor information, including temperature sensor information such as temperature threshold, whether it participates in heat dissipation speed regulation, heat dissipation area, and speed regulation parameters.

[0111] See Figure 4 The Sensor management module implements the following functions:

[0112] Step 1: The sensor management module loads the configuration file, generates the corresponding sensor management information based on the configuration file, and obtains the number of valid sensors;

[0113] Step 2: Traverse the sensor points to obtain sensor information, and perform alarm and de-alarm processing on the sensors;

[0114] Step 3: For dynamically registered sensors, the sensor management module updates the sensor management information;

[0115] Step 4: Dynamically deleted sensors are updated in the sensor management module with updated sensor management information;

[0116] Step 5: Dynamically modified sensors; the sensor management module updates sensor management information.

[0117] The fan cooling module consists of three parts: fan management, sensor point monitoring, and thermal management. Fan management: acquires fan information, controls the fan, and provides a fan information query interface. Sensor point monitoring: primarily obtains sensor point information from the sensor management module, including the heat dissipation zone to which the sensor belongs, the sensor value, and the corresponding PID information. Thermal management: mainly calculates the fan speed value of the heat dissipation zone based on the sensor information obtained from the sensor point monitoring service, and then sets the fan speed through the fan management service.

[0156] }

[0157] }

[0158] }

[0159] See Figure 5 The fan speed control module implements the following functions:

[0160] Step 1: Load the fan speed control configuration and initialize the fan management resources to determine the area where each fan is located, which fan is cooling which device, and the basic information such as the ID of each fan;

[0161] Step 2: Start the fan monitoring thread and the heat dissipation point sensor monitoring thread to obtain the temperature of each temperature point;

[0162] Step 3: The fan monitoring thread continuously tests the fan, obtains information such as fan presence, speed, and rotation speed, updates the fan health status according to changes in fan speed, and handles fan alarms and de-alarms according to status changes;

[0163] Step 4: The heat dissipation point sensor monitoring thread continuously monitors the sensor to obtain sensor information, including temperature, alarm status, etc., and determines the sensor information and speed adjustment parameters in each heat dissipation zone.

[0164] Step 5: Loop through all heat dissipation zones and calculate the fan speed in each zone.

[0165] Specifically, the fan speed adjustment process within each partition is as follows: First, the fan speed of each heatsink within the partition is calculated. For each heatsink sensor, its enabled status is checked; if disabled, it is skipped. The validity of the heatsink temperature is then determined (e.g., if the heatsink temperature exceeds 0-250 degrees Celsius, it is considered abnormal; otherwise, it is considered normal). If invalid, a backup temperature point is checked. If a backup temperature point exists, its speed is calculated; otherwise, the speed at which the sensor failed in the configuration is used for adjustment. Next, the fan speeds within the partition are calculated based on the temperatures of each heatsink within that partition; and the fan speeds in other partitions are calculated based on the temperatures of each heatsink within those partitions. The maximum speed corresponding to the same fan is selected as its speed, and then the fan speeds are updated based on the fan status.

[0166] This embodiment enables dynamic monitoring of the interface card. Based on the interface card's PN information, a configuration file is dynamically loaded to configure the interface card's sensor information and corresponding speed control parameters. This allows the system to automatically adapt to the appropriate speed control strategy based on the specific interface card model, improving the system's intelligence and flexibility. Furthermore, the sensor module can dynamically record and update sensor information, including updates to temperature sensor speed control parameters and changes in sensor names. This achieves real-time management and updating of sensor information, avoiding the tediousness and errors of manual adjustments and improving system reliability and maintainability. Further, the fan cooling module implements corresponding fan speed control strategies based on the association between the heat dissipation area and the fan in the configuration file. By periodically obtaining temperature sensor values ​​and alarm status from the sensor module, the fan speed is adjusted in real time, allowing the system to dynamically adjust the heat dissipation effect according to real-time environmental changes. This improves the system's heat dissipation efficiency and stability, reduces the workload of manual adjustments, and improves system maintenance efficiency and accuracy.

[0167] The following describes a fan speed control device provided in an embodiment of this application. The fan speed control device described below can be referred to in conjunction with other embodiments described herein.

[0170] The determination module is used to determine at least one temperature monitoring point corresponding to an interface card, as well as the fan zone and speed control parameters matched to the temperature monitoring point, based on the card information.

[0171] The monitoring module is used to monitor the temperature values ​​of the temperature monitoring points using a temperature monitoring thread;

[0172] The speed control module is used to calculate the fan speed in the corresponding fan zone based on the temperature value and speed control parameters, and select the maximum speed corresponding to the same fan as the working speed of that fan.

[0173] In one example, the module is specifically used for:

[0174] Initialize all slots in the current device;

[0175] The basic input / output system of the current device is used to traverse each slot to determine at least one target slot that is in operation;

[0176] Read card information of at least one interface card plugged into at least one target slot.

[0183] The enable judgment module is used to determine whether the temperature monitoring point is enabled. If the temperature monitoring point is enabled, the step of using the temperature monitoring thread to monitor the temperature value of the temperature monitoring point is executed; otherwise, the current temperature monitoring point is skipped.

[0184] In one example, it also includes:

If a backup temperature value exists, it uses the backup temperature value as the actual temperature value and then calculates the fan speed in the corresponding fan zone based on the temperature value and speed control parameters. If no backup temperature value exists, the module determines the target speed corresponding to the invalid temperature at the temperature monitoring point.
