Description

Temperature protection method of storage device and computer program product thereof

The present invention relates to temperature protection of storage devices, and in particular to a temperature protection mechanism that performs intelligent compensation based on temperature history records.

If the temperature of the storage device is too high, it will have many adverse effects. For example, it may cause performance degradation, hardware damage, data corruption and other problems. It may also increase the ambient temperature and affect surrounding hardware.

Among the current storage device temperature protection methods, one method is to check the temperature of the storage device with a fixed detection cycle. After the temperature of the storage device continuously exceeds the temperature protection threshold for a predetermined number of times, the temperature protection mechanism is activated to cause the storage device to Enter throttling mode to lower the temperature of the storage device.

However, this method cannot be adjusted for computer platforms with different execution environments and different heat dissipation conditions, and may result in unsatisfactory cooling effects on some platforms and continued decline in platform performance.

For example, assume that the temperature protection threshold of all computer platforms is set to 60°C, and is also set to regularly measure the temperature every five minutes. If the measured temperature exceeds the temperature protection threshold three times, the temperature protection mechanism is activated. Even if some of these computer platforms can successfully suppress the temperature and maintain better computer performance under the same temperature protection settings as mentioned above, on some computer platforms with harsher execution environments or poor heat dissipation conditions, problems may occur due to The same temperature protection settings mentioned above are not suitable for these platforms, missing the best opportunity to start cooling down.

After the temperature rises to a certain level, even if the temperature protection mechanism is subsequently activated, the temperature protection mechanism that responds too slowly may still be too late to lower the temperature to a normal range, causing the temperature protection mechanism to take a long time to be activated, causing the computer to take a long time. In a state of poor performance.

In view of this, the present invention intends to propose a temperature protection method for a storage device, which can record the temperature of the regularly inspected storage device and make a temperature history record. After recording for a period of time, the temperature history record can be used to adjust the temperature protection mechanism. Enable timing so that different platforms can perform better.

Regarding the temperature protection method of a storage device of the present invention, it includes: setting a temperature protection threshold based on the temperature history record of the storage device; periodically detecting the temperature of the storage device, and storing the detected temperature data in The temperature history is being recorded; and when it is detected that the temperature of the storage device continuously exceeds the temperature protection threshold for a predetermined number of times, the temperature protection mechanism of the storage device is activated.

Regarding a computer program product of the present invention, the program is loaded into a computer and executed: the first program instruction causes a processor to set a temperature protection threshold based on the temperature history record of a storage device; the second program instruction causes the processor to Detect the temperature of the storage device periodically; and a third program instruction is to activate the temperature protection mechanism of the storage device when the processor detects that the temperature of the storage device continuously exceeds the temperature protection threshold for a predetermined number of times.

The present invention has various implementation modes, and representative embodiments will be described in detail with reference to the drawings. These descriptive examples are given to introduce the reader to the general topics discussed here and are not intended to limit the scope of the concept of disclosure. Various additional features and examples are described in the following paragraphs with reference to the drawings, wherein like numerals designate like elements. The illustrated embodiments should not be used to limit the present disclosure. Components contained in this article may not be drawn to scale.

The protection scope of the present invention is defined by the patent application scope. The embodiments and drawings illustrated in the description are only examples or schematic diagrams of the principles of the present invention, and are not intended to limit the present invention to the embodiments. Those with ordinary knowledge in the art may make some changes and substitutions without departing from the spirit and scope of the present invention. The steps disclosed in the present invention do not have a certain sequence relationship, nor are they limited to being executed only once. The order of the steps can be adjusted according to the implementation method.

A step flow chart of an embodiment of a temperature protection method for a storage device according to the present invention is shown in Figure 1. In the temperature protection method of the storage device of the present invention, the temperature of the storage device is first detected in a preset period (step S11). For example, the preset cycle may be to perform temperature detection every 5 minutes, or to perform temperature detection every 3 minutes.

The specific method of detecting the temperature of the storage device can utilize existing technology. For example, the CPU can be allowed to read the temperature sensor built into the storage device, or a temperature sensor can be placed in a specific location of the storage device, and the CPU can read the output information of the temperature sensor.

The results of each periodic temperature detection will be recorded in the temperature history record (step S14). The temperature history record may be a record file or log stored in a storage device, which stores the results of temperature measurement over a period of time. For example, each time the temperature is detected, the CPU will update the temperature history record stored in the storage device and add the latest temperature detection result to the temperature history record.

Before the temperature protection threshold is set according to the temperature history record (step S15), the temperature protection threshold may be a preset value, such as 60°C, or any other suitable temperature. Before setting the predetermined number of times according to the temperature history record (step S15), the predetermined number of times may be a preset value, such as 3 times, or any other suitable number of times. Before the detection period is set according to the temperature history record (step S15), the detection period may be a preset value, such as 5 minutes, or any other suitable time. The method of setting the temperature protection threshold, the predetermined number of times, and/or the detection period based on the temperature history record (step S15) will be described in detail below.

In addition, after each periodic temperature detection (step S11), it will also be determined whether the detected temperature has continuously exceeded the temperature protection threshold for a predetermined number of times (step S12). If it is determined that the detected temperature has not continuously exceeded the temperature protection threshold for a predetermined number of times (step S12: No), the temperature protection mechanism will not be activated and the temperature will continue to be detected periodically (step S11).

If the detected temperature continuously exceeds the temperature protection threshold for a predetermined number of times, the temperature protection mechanism is activated (step S13), the temperature is detected periodically (step S11), and the detected temperature is stored in the temperature history record (step S14) Still ongoing. The above-mentioned temperature protection mechanism for activating the storage device can utilize existing methods. For example, the storage device enters throttling mode.

After the temperature history record is accumulated for a period of time, for example, after the detected temperature is stored in the temperature history record (step S14) for 30 days, the temperature protection method can be set based on the temperature history record (step S15). Setting the temperature protection method includes setting the temperature. Protection threshold, set detection period, and/or set a predetermined number of times exceeding the temperature protection threshold.

There are many ways to set the temperature protection method based on the temperature history record. For example, the temperature protection threshold, the detection period, and/or the predetermined number of times can be set based on the average temperature of the temperature history record. It is also possible to perform statistical analysis on the temperature history records based on existing analysis techniques to obtain the better temperature protection threshold, the detection period, and/or the predetermined number of times for setting.

The setting method of one of the temperature protection methods is shown in Table 1 below. average temperature Temperature protection threshold predetermined times Detection cycle x＜40℃ 60℃ 3 times (default value) 5 points (default value) 40℃＜x＜50℃ 50℃ 3 times 5 points 50℃＜x＜60℃ 45℃ 2 times 5 points x>60℃ 40℃ 2 times 5 points Table 1 Setting method of a temperature protection method

If in the temperature history record, the average temperature of the temperature history record over a period of time is less than 40°C, it means that the platform is well adapted to the original temperature protection method. Therefore, the temperature protection threshold setting can continue to be maintained at the default 60°C. C. The setting of the specified number of times continues to be the default 3 times, and the setting of the detection period continues to be the default 5 minutes.

If in the temperature history record, the average temperature of the previous temperature history record is between 40°C and 50°C, adjust the temperature protection threshold slightly downward and set it to 50°C to enable the temperature protection mechanism. Starts up faster and cools down immediately to maintain computer performance. In this embodiment, the settings of the predetermined number of times and the detection period can still maintain the default values. In some other embodiments, the predetermined number of times and the detection period can also be adjusted synchronously.

If in the temperature history record, the average temperature of the temperature history record over a period of time is between 50 and 60°C, adjust the temperature protection threshold downward to a lower 45°C, and set the predetermined number of times to 2 , so that the temperature protection mechanism starts faster.

If in the temperature history record, the average temperature over a period of time is higher than 60°C, the temperature protection threshold is set to 40°C in order to achieve a rapid cooling effect and avoid the need to activate the temperature protection mechanism for a long time once the temperature soars. , leading to a decrease in performance.

The setting method of another temperature protection method is shown in Table 2 below. average temperature Temperature protection threshold predetermined times Detection cycle x＜40℃ 60℃ 3 times (default value) 5 points (default value) 40℃＜x＜50℃ 50℃ 3 times 5 points 50℃＜x＜60℃ 45℃ 3 times 3 points x>60℃ 40℃ 3 times 3 points Table 2 Setting method of another temperature protection method

As shown in Table 2, in this method, the set times are kept at the default 3 times without adjustment. However, when the average temperature recorded in the temperature history increases, the detection period will be gradually shortened. In this way, when the average temperature recorded in the temperature history of the platform is higher, the set detection period becomes shorter, which shortens the time for subsequent detection of the temperature exceeding the predetermined number of times, and enables early detection of temperature overshoots. high and activate the effect of the temperature protection mechanism. If in the temperature history record, the average temperature of the temperature history record over a period of time is less than 40°C, it means that the platform is well adapted to the original temperature protection method. Therefore, the temperature protection threshold setting can continue to be maintained at the default 60°C. , the setting of the predetermined number of times can continue to maintain the default 3 times, and the setting of the detection period can continue to maintain the default 5 minutes.

If in the temperature history record, the average temperature of the previous temperature history record is between 40°C and 50°C, adjust the temperature protection threshold slightly downward and set it to 50°C to enable the temperature protection mechanism. Starts up faster and cools down immediately to maintain computer performance. In this embodiment, the settings of the predetermined number of times and the detection period can still maintain the default values.

If the average temperature of the temperature history record over a period of time is between 50 and 60°C, adjust the temperature protection threshold downward to a lower 45°C and set the detection period to 3 minutes to enable the temperature protection mechanism to activate faster.

If in the temperature history record, the average temperature over a period of time is higher than 60°C, the temperature protection threshold is set to 40°C in order to achieve a rapid cooling effect and avoid the need to activate the temperature protection mechanism for a long time once the temperature soars. , leading to a decrease in performance.

The setting method of another temperature protection method is shown in Table 3 below. average temperature Temperature protection threshold predetermined times Detection cycle x＜40℃ 60℃ 3 times (default value) 5 points (default value) 40℃＜x＜50℃ 50℃ 3 times 5 points 50℃＜x＜60℃ 45℃ 3 times 3 points x>60℃ 45℃ 2 times 3 points Table 3 Setting method of another temperature protection method

In the embodiment shown in Table 3, the temperature protection threshold, the predetermined number of times, and the detection period are all adjusted based on the average temperature in the temperature history record.

If in the temperature history record, the average temperature of the temperature history record over a period of time is less than 40°C, it means that the platform is well adapted to the original temperature protection method. Therefore, the temperature protection threshold setting can continue to be maintained at the default 60°C. , the setting of the predetermined number of times can continue to maintain the default 3 times, and the setting of the detection period can continue to maintain the default 5 minutes.

If in the temperature history record, the average temperature of the previous temperature history record is between 40°C and 50°C, adjust the temperature protection threshold slightly downward and set it to 50°C to enable the temperature protection mechanism. Starts up faster and cools down immediately to maintain computer performance. In this embodiment, the settings of the predetermined number of times and the detection period can still maintain the default values.

If the average temperature of the temperature history record over a period of time is between 50 and 60°C, adjust the temperature protection threshold downward to a lower 45°C and set the detection period to 3 minutes to enable the temperature protection mechanism to activate faster.

If in the temperature history recording, the average temperature for a period of time is higher than 60°C, set the temperature protection threshold to 45°C, set the predetermined number of times to 2, and set the detection cycle to 3 minutes in order to achieve rapid The cooling effect prevents the temperature protection mechanism from being activated for a long time once the temperature soars, resulting in a decrease in performance.

The above-mentioned adjustment methods of the temperature protection threshold, predetermined times, and detection periods are not limited to this, nor are they limited to adjustment based on the average value of the temperature history records. The values of the temperature protection threshold, predetermined times, and detection periods can be based on Various settings can be made for the analysis results of temperature history records.

For example, the above-mentioned adjustment of the temperature protection threshold, predetermined times, and detection period can be adjusted based on the mode, maximum value, minimum value, or any other calculated value of the temperature history record. In some special embodiments, the values in the temperature history record can also be calculated through mathematical models to set the temperature protection mode.
