Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations (or steps) may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

FIG. 1 is a flow chart of a temperature control method for a storage device provided in an embodiment of the present invention. The embodiments of the present invention are applicable to the situation of heat dissipation and cooling of a storage device, especially the situation of heat dissipation and cooling of a storage device of a high-density hard disk. The temperature control method of the storage device can be executed by the temperature control device of the storage device. The temperature control device of the storage device can be realized by software and/or hardware, and can be integrated on any electronic device with network communication function. As shown in FIG. 1, the temperature control method of the storage device provided in the embodiment of the present invention may specifically include the following steps:

S110. Determine the thermal distribution information of the hard disk temperature used in the current period of the storage device; the thermal distribution information of the hard disk temperature is used to describe the temperature relationship between the hard disks in each slot in the storage device.

Referring to FIG. 2 , the storage device includes a plurality of slots, and a hard disk can be installed in each slot. Considering the high cost of construction space in the computer room, the positions of the slots in the storage device are arranged close to each other, which causes the hard disks installed in the slots to also be arranged in close proximity, and high-density hard disks are installed in the storage device. Realize high-density storage of storage devices. In this way, according to the hard disk temperature of each hard disk internally set at high density during the normal operation of the storage device, the thermal distribution information of the hard disk temperature used by the storage device under the current situation can be determined. Optionally, in a stable system, a disk thermal distribution map is generated according to the thermal distribution information of the disk temperature, indicating the temperature relationship between the hard disks in different slots.

Under the condition that the position and type of the hard disk in the storage device do not change, the temperature relationship among the hard disks in the storage device in a stable storage system is usually relatively fixed. For example, the thermal distribution information of the hard disk temperature can describe the temperature variation among the hard disks in each slot in the storage device, so that the relationship between the high and low temperatures of the hard disks in each slot in the storage device can be known. Optionally, determining the temperature thermal distribution information of the hard disk used in the current cycle of the storage device may include: periodically polling the temperature of the hard disk in each slot in the storage device to generate the thermal distribution information of the temperature of the hard disk used in the current cycle of the storage device; or, in Periodically poll the temperature of the hard disk in each slot in the storage device to generate the hard disk temperature thermal distribution information, save the hard disk temperature thermal distribution information, and directly extract the hard disk temperature determined and stored in advance from the saved content when needed Thermal distribution information.

S120. According to the temperature and thermal distribution information of the hard disk, determine the hard disk to be queried that is used in the current cycle from the hard disks of the storage device.

In the storage system, the hard disk in the storage device is a component that generates a lot of heat in the storage system. In order to ensure that the storage device can dissipate heat in a timely manner, it is usually necessary to detect the temperature information of the hard disk to adjust the heat dissipation intensity of the storage device for cooling. Fan speed to cool down and dissipate heat. However, reading the temperature of the hard disk will bring additional read operations to the hard disk, especially in storage devices with high-density hard disks. There are a lot of hard disks. If a large number of hard disk read operations are performed on the hard disk, the system performance will be seriously degraded.

Considering the read impact caused by a large number of polling hard disks in the storage device, the hard disks in each slot of the storage device can be selected according to the temperature relationship between the temperature of the hard disks in each slot in the storage device indicated by the thermal distribution information of the hard disk temperature. The hard disk used for temperature query is used as the hard disk to be queried. Optionally, record the screened hard disk information of the hard disk to be queried in the list of hard disks to be queried, so that in the subsequent cooling control process, only the hard disks recorded in the list of hard disks to be queried are polled for temperature, and the temperature reading of the hard disk is reduced as much as possible. The additional read operations brought to the hard disk minimize the impact of the hard disk temperature query on system performance.

S130. When temperature control is performed in the current cycle, the temperature of the hard disk to be queried is detected, and the heat dissipation intensity of the storage device is adjusted to cool down.

Since there is a fixed temperature relationship between the hard disks in each slot in the storage device, the selected hard disks to be queried can reflect the temperature of other hard disks to a certain extent. Therefore, in the process of cooling the storage device, only The temperature detection of the screened hard disks to be queried that meet the requirements can accurately and effectively dissipate heat and cool down the storage devices in different hard disk environments for high-density storage, so as to ensure that the hard disks work under reasonable temperature conditions. For example, if the storage device includes X hard disks, only the temperature of the selected Y hard disks to be queried is queried each time, and the temperature of the next Y hard disks to be queried is queried at preset intervals to adjust the heat dissipation intensity of the storage device Cool down.

Optionally, the temperature control for the storage device can be divided into multiple temperature control cycles. When entering a temperature control cycle, the temperature and thermal distribution information of the hard disk used by the storage device in the current cycle can be determined, and can be repeated during the temperature control process of the current cycle. The hard disks to be queried are screened based on the thermal distribution information of the hard disk temperature in the current period, so that it is not necessary to frequently determine the thermal distribution information of the hard disk temperature and frequently screen the hard disks to be queried.

Optionally, adjusting the heat dissipation intensity of the storage device to cool down may include the following operations: when entering the cooling control phase, increasing the heat dissipation intensity of the storage device to increase the fan speed to cool down; or, entering the cooling control phase to cool down and the cooling does not meet the requirements When required, maintain the heat dissipation intensity of the storage device to maintain a fixed fan speed for cooling and heat dissipation; or enter the cooling control stage for cooling and gradually reduce the heat dissipation intensity of the storage device when the cooling meets the requirements to gradually reduce the fan speed for cooling and heat dissipation.

According to the temperature control scheme of the storage device provided in the embodiment of the present invention, for a storage device with a high-density hard disk, the hard disk that meets the requirements will be selected according to the temperature and thermal distribution of the hard disk in the storage device, and only the hard disk that meets the requirements will be selected during cooling control. The temperature query of the hard disk avoids the temperature query of a large number of hard disks in high-density storage devices, reduces the extra read operations caused by the hard disk temperature reading to the hard disk, and thus avoids the system performance due to the hard disk temperature read operation. It can also control and adjust the heat dissipation intensity to cool down by querying the temperature of the hard disk that meets the requirements. At the same time, it can effectively control the heat dissipation of high-density storage in different hard disk configuration environments to ensure that the hard disk works under reasonable temperature conditions.

Fig. 3 is a flow chart of another temperature control method for a storage device provided in an embodiment of the present invention. The embodiments of the present invention are optimized on the basis of the foregoing embodiments, and the embodiments of the present invention may be combined with various optional solutions in the foregoing one or more embodiments. As shown in FIG. 3, the temperature control method of the storage device provided in the embodiment of the present invention may specifically include the following steps:

S310. Determine the hard disk presence information of each slot in the storage device in the current cycle; the hard disk presence information is used to indicate whether a hard disk is installed in the slot.

The temperature control for the storage device can be divided into multiple temperature control cycles. In different cycles, whether the hard disk is installed in each slot in the storage device will change, so the hard disk presence information in each slot in the storage device will also change. Change.

S320. Obtain temperature thermal distribution information of the hard disk used in the storage device in the current cycle by performing temperature query on the hard disk in the storage device according to the presence information of the hard disk in the current cycle.

Wherein, the thermal distribution information of the hard disk temperature may be used to describe the temperature relationship between the hard disks in each slot in the storage device (for example, the relationship between high and low temperature changes). Use the hard disk presence information to indicate which slots in the storage device need to be queried for the temperature of the hard disks, so as to avoid invalid query for the slots without hard disks.

In an optional solution of this embodiment, according to the in-position information of the hard disk, the temperature and thermal distribution information of the hard disk is obtained by querying the temperature of the hard disk in the storage device, which may include steps A1-A2:

Step A1, determine the hard disk distribution table in the storage device according to the hard disk presence information

Step A2. Perform temperature query on the hard disks installed in the slots of the storage device according to the hard disk distribution table, and generate hard disk temperature thermal distribution information including the temperature relationship between the hard disks in each slot in the storage device according to the temperature query results.

According to the indication of the hard disk presence information, it can be known whether a hard disk is installed in each storage slot, so that the hard disk distribution table of the hard disk in the storage device can be known. The hard disk distribution table records which slots of the storage device are installed with hard disks, and indicates which slots are not installed with hard disks. According to the hard disk distribution table, the temperature information of all hard disks in the storage device can be queried, and the hard disk temperature thermal distribution information used to represent the temperature relationship between the hard disks in each slot is generated according to the queried temperature information of each hard disk.

Optionally, when the location of the hard disk in the storage device or the insertion or removal of the hard disk is changed, the hard disk distribution table used by the storage device and the thermal distribution information of the hard disk temperature are also updated at any time, for example, re-acquire the temperatures of all disks in the storage device system and find out The disks in the hot slot positions form a disk heat map list table as the hard disk temperature thermal distribution information, and then reorder according to the position changes of each operating hard disk in the storage device.

Optionally, the thermal distribution information of the hard disk temperature can be directly calibrated and generated based on the hard disk position of the hard disk in each slot queried and the hard disk temperature. At this time, the thermal power of each position in the thermal distribution information of the hard disk temperature can be described by the hard disk temperature. Alternatively, the thermal distribution information of the hard disk temperature can be generated based on normalization of the hard disk position and the hard disk temperature of the hard disk in each slot queried, and then calibrated. At this time, the thermal power of each position in the hard disk temperature thermal distribution information can use The normalized processing value of the hard disk temperature is described. Although the thermal power is not directly described by temperature, it can represent the temperature relationship between the hard disks in each slot.

S330. Determine, from the hard disks of the storage device, the hard disk to be queried that is used in the current cycle according to the temperature and thermal distribution information of the hard disk.

In an optional solution of this embodiment, according to the thermal distribution information of the temperature of the hard disk, determining the hard disk to be queried in the current cycle from the hard disk of the storage device may include steps B1-B2:

Step B1, according to the temperature and thermal power of the hard disks in each slot indicated by the hard disk temperature and thermal distribution information, sort the hard disks in the storage device in descending order of temperature and thermal power.

Step B2. Based on the sorting result, at least one hard disk is selected from the hard disks sorted before as the hard disk to be queried for the current cycle.

The hard disk temperature and heat distribution information indicates the temperature and heat of the hard disk in each slot. In the temperature and heat distribution diagram, a larger temperature and heat indicates a higher temperature of the hard disk at the corresponding location, and a smaller temperature and heat indicates that the temperature of the hard disk at the corresponding location is lower. By sorting the hard disks in each slot in the storage device, the hard disks can be sorted in descending order of temperature and thermal power, and then you can know which hard disks have higher temperatures in the storage device, and which hard disks have lower temperatures .

According to the sorting results of the hard disks, you can select a preset hard disk from the hard disks sorted first, that is, select a preset hard disk from the hard disks with high temperature as the hard disk to be queried in the current cycle, and filter out the hard disk to be queried The hard disk information of the hard disk is recorded in the list of hard disks to be queried, so that in the subsequent cooling control process, only the hard disks recorded in the list of hard disks to be queried are polled for temperature. In this way, only polling the temperature of these disks each time has the advantage of reducing the read impact caused by polling all disks, and can more effectively focus on the possible hot disks for queries.

As an optional solution, referring to FIG. 2 , the slot arrays for carrying hard disks in the storage device are arranged in a distributed manner (such as row and column distribution settings), and the hard disks in the storage device can be divided into at least A group of hard disks in an array, so that the hard disks in the storage device can be divided into regions according to the array. Optionally, sorting the hard disks in the storage device in descending order of temperature and thermal power may include the following operations: For each group of hard disks in the array, according to the temperature and thermal power of the group of hard disks in the array, the order of temperature and thermal power is from large to small The group of array hard disks in the storage device is sequentially sorted to obtain a sorting result of each group of array hard disks. Correspondingly, for the hard disks in each group of arrays, the highest-ranked hard disks in each group of hard disks in the array can be screened out to obtain the hard disks to be queried.

For example, referring to Fig. 2, the storage device may include 12 slots, No. 1, No. 2 and No. 3 slots are located in the first row, and No. 4, No. 5 and No. 6 slots are located in the second row, so that And so on. If hard disks are installed in slots 1, 2, and 3 of the first row, according to the thermal distribution diagram of the hard disk temperature, the hard disks in the first row are sorted according to the temperature from high to low as No. 3, No. 2, and No. 1. , only the hard disk temperature in slot 3 is queried. If only one hard disk is installed in the first row, only this one hard disk can be queried. If only the hard disks in slots 1 and 2 are installed in the first row, sort the hard disks in the first row according to the temperature from high to low as No. 2 and No. 1. At this time, only the hard disk temperature in slot 2 is queried.

S340. When performing temperature control in the current cycle, adjust the heat dissipation intensity of the storage device to cool down by performing temperature detection on the hard disk to be queried.

In another optional solution of this embodiment, according to the thermal distribution information of the hard disk temperature, determining the hard disk to be queried in the current cycle from the hard disk of the storage device may include the following steps: Select a preset hard disk as the hard disk to be queried for the current cycle.

Referring to Fig. 2, in the optional solution of the aforementioned embodiment, the list of hard disks to be queried can be screened and determined according to the thermal distribution map of hard disk temperature, and the hard disks to be queried may be concentrated in {3, 6, 9, 12}. hard disk slot. In this way, only the temperature of these disks is polled each time to reduce the read impact caused by polling all disks, and only the hard disks in slots {3, 6, 9, 12} are queried each time, so that these hard disks are always loaded The read operation caused by temperature control may affect the performance of these hard disks.

In a stable system, the temperature relationship between the hard disks is fixed, so the relationship between the hard disk temperatures in each slot can be obtained according to the thermal distribution diagram of the hard disk temperature, then the temperature difference between slot 1 and slot 3 is basically fixed. At this time, you can choose not to read the hard disk temperature of the first slots such as {3, 6, 9, 12}, etc., but randomly read the part of the hard disk in each slot indicated in the temperature thermal distribution diagram. The hard disks in other slots are used as the hard disks to be queried, and the cooling threshold used for the cooling detection of randomly selected hard disks can be calculated according to the positions of the hard disks in each slot and the temperature difference between the hard disks.

Under the premise of knowing the position of the hard disk in each slot and the temperature difference relationship between each hard disk, through the corresponding cooling of the hard disk with the highest temperature thermal ranking (such as the hard disk in the slots {3, 6, 9, 12}) The temperature drop threshold corresponding to the randomly selected hard disk can be obtained by calculating the threshold. For example, the temperature of the hard disk in slot 1 in the storage device is 50 degrees Celsius, and the temperature of the hard disk in slot 3 is 55 degrees Celsius. In a stable system, the temperature difference between the above two hard disks is usually 5 degrees Celsius. Suppose the system stipulates that the cooling threshold of the hard disk in slot 3 is 55 degrees Celsius, and the fan speed needs to be increased if it is higher than 55 degrees Celsius, then when the hard disk in slot 1 randomly selected in the hard disk list is read, the hard disk in slot 1 The cooling threshold of the raised fan is 50 degrees Celsius based on the temperature difference of 5 degrees Celsius. Optionally, the cooling threshold of fan speed adjustment designed in the storage system is not a fixed value, but different thresholds are set according to hard disks at different temperature thermal map positions.

According to the temperature control scheme of the storage device provided in the embodiment of the present invention, for a storage device with a high-density hard disk, the hard disk that meets the requirements will be selected according to the temperature and thermal distribution of the hard disk in the storage device, and only the hard disk that meets the requirements will be selected during cooling control. The temperature query of the hard disk avoids the temperature query of a large number of hard disks in high-density storage devices, reduces the extra read operations caused by the hard disk temperature reading to the hard disk, and thus avoids the system performance due to the hard disk temperature read operation. It can also control and adjust the heat dissipation intensity to cool down by querying the temperature of the hard disk that meets the requirements. At the same time, it can effectively control the heat dissipation of high-density storage in different hard disk configuration environments to ensure that the hard disk works under reasonable temperature conditions.

Fig. 4 is a flowchart of another temperature control method for a storage device provided in an embodiment of the present invention. The embodiments of the present invention are optimized on the basis of the foregoing embodiments, and the embodiments of the present invention may be combined with various optional solutions in the foregoing one or more embodiments. As shown in FIG. 4, the temperature control method of the storage device provided in the embodiment of the present invention may specifically include the following steps:

S410. Determine the temperature thermal distribution information of the hard disk used in the current cycle of the storage device; the hard disk temperature thermal distribution information is used to describe the temperature relationship between the hard disks in each slot in the storage device.

S420. Determine, from the hard disks of the storage device, the hard disk to be queried that is used in the current cycle according to the temperature and thermal distribution information of the hard disk.

S430. When performing temperature control in the current cycle, query to determine whether the temperature of the hard disk to be queried is greater than a corresponding preset cooling threshold.

Wherein, the preset cooling threshold corresponding to the hard disk in each slot is configured according to the distribution position of the hard disk in each slot indicated by the thermal distribution information of the hard disk temperature and the temperature difference between the hard disks in each slot.

In a stable storage system, the temperature relationship between the hard disks is fixed, so the relationship between the high and low temperatures of the hard disks in each slot can be obtained according to the thermal distribution diagram of the hard disk temperature, so that the temperature relationship between the hard disks in each slot in the storage device can be determined. Set the cooling threshold of the hard disks in each slot based on the temperature difference between them. When performing temperature control in the current cycle, by detecting the temperature of the hard disk to be queried, adjusting the heat dissipation intensity of the storage device to cool down may include the following operations: performing a read operation of temperature information on the hard disk to be queried, and reading the temperature of the hard disk to be queried , and determine whether the temperature of the hard disk to be queried is greater than a preset cooling threshold corresponding to the hard disk to be queried. In this way, it is possible to avoid frequent reading operations on the hard disk devices of the storage device to obtain the temperature of each hard disk, thereby avoiding occupying too much bandwidth resources of the hard disk; at the same time, due to the fixed relationship between the hard disks, only need By determining the temperature of some of the hard disks, it is possible to accurately monitor the temperature of each hard disk, which can adapt to the uneven heat dissipation of high-density storage hard disks.

S440. If it is determined that the temperature of the hard disk to be queried is greater than the corresponding preset cooling threshold, increase the heat dissipation intensity of the storage device to cool down the hard disk in the storage device, and add the hard disk to be queried to the list of hard disks to be cooled for subsequent use. Cool down the hard disks to be queried in the cooling hard disk list.

When it is found that the temperature of a hard disk to be queried is higher than the preset cooling threshold, the speed of the cooling fan used for cooling and heat dissipation in the storage device can be increased, and the high-density hard disk in the storage device can be cooled by adjusting the speed of the fan. At the same time, hard disks to be queried whose temperature is higher than the preset cooling threshold can also be placed in the list of hard disks to be cooled. The list of hard disks to be cooled is used to store information about hard disks whose temperature is higher than the safe cooling threshold. It is necessary to periodically obtain the temperature of the hard disks to be queried in the list of hard disks to be cooled to accurately control the temperature without re-screening other hard disks. In this way, the design of the list of hard disks to be cooled can ensure more accurate control of the temperature of the storage system, and prevent the problem of overheating of the hard disks in the areas where the fan is turned back and forth and the heat dissipation may be difficult.

In an optional solution of this embodiment, by performing temperature detection on the hard disk to be queried and adjusting the heat dissipation intensity of the storage device to cool down, the following operations may also be included:

After cooling down, if any hard disk to be inquired is detected in the list of hard disks to be queried to be cooled down, continue to maintain the heat dissipation intensity of the storage device for cooling down or increase the heat dissipation intensity of the storage device again for cooling down.

After it is determined that the temperature of the hard disk to be queried is greater than the corresponding preset cooling threshold, and the heat dissipation intensity of the storage device is increased to cool down the hard disk in the storage device, the temperature of the hard disk in each slot in the storage device may change (including temperature rise High or low), for this reason, after cooling the heat dissipation intensity of the entire storage device, the cooling control can be continued. In the subsequent cooling control process, it can be directly determined whether there is any hard disk to be queried in the hard disk list to be queried and cooled. As long as there is a hard disk in the list of hard disks to be queried to be cooled, the fan speed of the storage system will be increased or maintained until Decrease the fan speed of the storage system only after the list of hard disks to be cooled is empty.

In an optional solution of this embodiment, by performing temperature detection on the hard disk to be queried and adjusting the heat dissipation intensity of the storage device to cool down, the following operations may also be included:

After cooling down, if it is detected that there is no hard disk to be queried in the list of hard disks to be queried to be cooled down, the heat dissipation intensity of the storage device is reduced to cool down after a preset delay time. For example, when it is detected that there is no hard disk to be queried in the list of hard disks to be queried and to be cooled, a preset delay time N is used to reduce the speed of the system fan to cool down the temperature. Wherein, the preset delay time for reducing the fan speed of the storage system can be set according to the temperature query interval period of the hard disk to be queried in the hard disk to be queried list and the hard disk layout of the storage system.

In an optional solution of this embodiment, by detecting the temperature of the hard disk to be queried and adjusting the heat dissipation intensity of the storage device to cool down, it may also include: periodically polling the temperature of the hard disk to be queried in the list of hard disks to be cooled, and checking the temperature of the hard disk to be queried. When it is determined that the temperature of the hard disk to be queried is lower than the corresponding preset cooling threshold, the temperature to be queried is removed from the list of hard disks to be cooled. Optionally, after the temperature to be queried is removed from the list of hard disks to be cooled, the following operations may also be included: if it is detected that the temperature of the hard disk to be queried is greater than the corresponding preset cooling threshold, then the hard disk to be queried is added to the hard disk to be cooled again List.

In an optional solution of this embodiment, every preset interval period, such as an interval of n minutes, performs temperature scanning and reading on the hard disks in all slots in the storage device or selects different temperature difference areas according to the thermal distribution information of the hard disk temperature. Scan the temperature of the hard disk to obtain the thermal temperature difference of the new hard disk in different slots in the storage device. For example, in Figure 2, the temperature difference between the hard disk in slot 1 and the hard disk in slot 3 may no longer be 5 degrees Celsius, but is the temperature difference that becomes x degrees Celsius.
