[0057] In order to make the above objectives, features and advantages of the present application more apparent and comprehensible, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] Referring to Figure 1 , a step flow chart of a data storage management method embodiment of the present application is shown, which can specifically include the following steps:

[0059] Step 101, obtaining initial storage data;

[0060] When there is a need to store data of a hard disk, the data that needs to be stored, i.e., initial storage data, can be obtained. The initial storage data can come from a server, a processing terminal, etc., and the source of the initial storage data is not limited. The type of the initial storage data can be cold data, hot data, or warm data; wherein, the hot data refers to frequently accessed online data, which has a high requirement on storage performance. The cold data refers to infrequently accessed offline data, such as backup and archive data, which has a relatively low requirement on storage performance and requires a large-capacity storage medium. The access frequency and requirement on storage performance of the warm data are between those of the hot data and the cold data.

[0061] Step 102, storing the initial storage data to an initial hard disk hibernation area matching the capacity of the initial storage data;

[0062] After obtaining the initial storage data, the capacity of the initial storage data can be determined to determine an initial hard disk hibernation area matching the capacity of the initial storage data, and the initial storage data is stored to the initial hard disk hibernation area for pre-storage based on the capacity of the initial storage data.

[0063] It should be noted that there can be multiple initial hard disk hibernate areas, and different initial hard disk hibernate areas are used to store initial storage data of different capacity sizes. For example, there can be four initial hard disk hibernate areas: a.zone hibernate area, b.zone hibernate area, c.zone hibernate area, and z.zone hibernate area. The a.zone is used to store initial storage data with a capacity less than 16K (bytes); the b.zone hibernate area is used to store initial storage data with a capacity greater than 16K and less than 256K; the c.zone hibernate area is used to store initial storage data with a capacity greater than 256K and less than 1024K; and the z.zone hibernate area is used to store initial storage data with a capacity greater than 1024K.

[0064] Step 103, upon receiving a read request for the initial storage data, obtaining a current timestamp, and adding the current timestamp to the initial storage data to generate target storage data;

[0065] After the initial storage data is pre-stored in the initial hard disk hibernate area, there can be a read request for the initial storage data. The read request for the initial storage data can be received, and the initial storage data can be read from the initial hard disk hibernate area in response to the read request; at the same time, a current timestamp corresponding to the current actual time can be obtained, such as 14:38; and the current timestamp can be added to the initial storage data to generate target storage data, i.e., the target storage data is storage data carrying the current timestamp.

[0066] In addition, when the target storage data is generated and a read request for the initial storage data is also received, a new current timestamp can be obtained, and the current timestamp in the target storage data can be updated.

[0067] It should be noted that the granularity of the current timestamp can be minutes, seconds, milliseconds, microseconds, etc., and the granularity of the timestamp is not limited.

[0068] Step 104, starting a preset data analysis period, and generating a frequency label corresponding to the target storage data based on the starting time data of the preset data analysis period and the target storage data;

[0069] When it is necessary to analyze the target storage data to determine its read frequency, the preset data analysis period is started; the read frequency of the target storage data is analyzed by starting the preset data analysis period. According to the difference between the starting time data of the preset data analysis period and the target storage data, the frequency label corresponding to the read frequency of the target storage data is determined. The frequency label is used to represent the read frequency level of the target storage data; for example, the frequency label can be A, B, C, and D; the read frequency level of A level is frequent; the read frequency level of B level is general; the read frequency level of C level is less frequently read; and the read frequency level of D level is not read.

[0070] In addition, in order to avoid affecting other running processes in the data analysis process, the data analysis can be performed at the trough of the device data processing, such as at the low peak of 24h data in the early morning.

[0071] Step 105, according to the frequency label, determine the target hard disk hibernation area, the target hard disk hibernation area is different from the hibernation depth of the initial hard disk hibernation area;

[0072] The frequency label corresponds to the hard disk hibernation area with different reading frequency. When the frequency label corresponding to the target storage data is determined, the hard disk hibernation area corresponding to the frequency label is determined as the target hard disk hibernation area. The hibernation depth of the target hard disk hibernation area is different from that of the initial hard disk hibernation area; and the physical hard disk corresponding to the target hard disk hibernation area and the initial hard disk hibernation area can be the same, that is, the target hard disk hibernation area and the initial hard disk hibernation area are the hibernation areas corresponding to the same physical hard disk in different stages.

[0073] Step 106, after the end of the current cycle period, move the initial storage data from the initial hard disk hibernation area to the target hard disk hibernation area.

[0074] When the current cycle period of data analysis ends, the data can be moved. At this time, the initial storage data can be moved from the original initial hard disk hibernation area to the target hard disk hibernation area according to the target hard disk hibernation area determined by the frequency label; the initial storage data is stored in the target hard disk hibernation area and enters the target hard disk hibernation area hibernation, so that the data with the same reading frequency level can be stored in the same target hard disk hibernation area, and the data in a target hard disk hibernation area has the same reading frequency, which can obtain more hibernation time to reduce the power consumption of the hard disk.

[0075] The embodiment of the present application acquires initial storage data, stores the initial storage data to an initial hard disk hibernation area matching the capacity of the initial storage data, acquires a current timestamp when a read request for the initial storage data is received, and generates target storage data by adding the current timestamp to the initial storage data, starts a preset data analysis period, generates a frequency label corresponding to the target storage data based on the start time data of the preset data analysis period and the target storage data, determines a target hard disk hibernation area according to the frequency label, the target hard disk hibernation area has a different hibernation depth from the initial hard disk hibernation area, and moves the initial storage data from the initial hard disk hibernation area to the target hard disk hibernation area after the current cycle period ends. The initial storage data is pre-judged to fall into the corresponding hibernation area, and then the initial storage data is stored in the target hard disk hibernation area matching the read frequency based on the use frequency of the initial storage data, so that the hard disk in shallow hibernation can be frequently awakened, the hard disk in deep hibernation can be avoided from being frequently awakened, and the purpose of reducing overall power consumption is achieved.

[0076] Referring to Figure 2 , a step flowchart of another data storage management method embodiment of the present application is shown, and the data storage management method can specifically include the following steps:

[0077] Step 201, when the hard disk is in a hibernation state, the hard disk is divided into a plurality of hard disk hibernation areas according to the address of the hard disk; the divided hard disk hibernation area is provided with a plurality of storage hard disks;

[0078] When the hard disk is in a hibernation state, the data in the hard disk will not be read and written, at this time, the hard disk can be divided into hibernation areas according to the address, and the areas corresponding to the address are divided into a plurality of hard disk hibernation areas. Different divided hard disk hibernation areas are used to store data of different capacities or different read frequencies. Each divided hard disk hibernation area is provided with a plurality of storage hard disks; since the storage data capacity is different, the corresponding capacity, i.e. the number of storage hard disks, can be different; and the storage hard disks in the divided hard disk hibernation area can be numbered to facilitate identification of the storage hard disks.

[0079] For example, based on the hibernation state of the hard disk, the a.zone hard disk hibernation area, the b.zone hard disk hibernation area, the c.zone hard disk hibernation area, and the z.zone hard disk hibernation area are divided according to the address area.

[0080] The storage hard disks in the area entering the a.zone are numbered as n1.azone, …, nx.azone. The storage hard disks in the area entering the b.zone are numbered as n1.bzone, …, nx.bzone. The storage hard disks in the area entering the c.zone are numbered as n1.czone, …, nx.czone. The storage hard disks in the area entering the z.zone are numbered as n1.zzone, …, nx.zzone. The number of the storage hard disks corresponding to the a.zone hard disk hibernation area, the b.zone hard disk hibernation area, the c.zone hard disk hibernation area, and the z.zone hard disk hibernation area can satisfy: z.zone hard disk hibernation area > c.zone hard disk hibernation area > b.zone hard disk hibernation area > a.zone hard disk hibernation area. It should be noted that the number of the storage hard disks corresponding to each divided hard disk hibernation area is not fixed and can be dynamically adjusted based on the use case.

[0081] In step 202, initial storage data is obtained.

[0082] After the hard disk hibernation areas are divided, when an IO (Input / Output) arrives each time, the initial storage data carried by the IO is obtained.

[0083] In step 203, the initial storage data is stored in an initial hard disk hibernation area matching the capacity of the initial storage data.

[0084] In the embodiment of the present application, the divided hard disk hibernation area is the initial hard disk hibernation area when pre-storing the initial storage data. After receiving the initial storage data, the initial storage data can be stored in the matching initial hard disk hibernation area according to the capacity of the initial storage data.

[0085] Specifically, the plurality of divided hard disk hibernation areas correspond to different capacity ranges, and the step of storing the initial storage data in an initial hard disk hibernation area matching the capacity of the initial storage data can include the following sub-steps:

[0086] In sub-step S2031, the capacity of the initial storage data is determined.

[0087] In actual application, different divided hard disk hibernation areas, i.e., different initial hard disk hibernation areas, correspond to different capacity ranges; for example, the capacity range of the a.zone hard disk hibernation area is less than 16K, the capacity range of the b.zone hard disk hibernation area is greater than 16K and less than 256K, the capacity range of the c.zone hard disk hibernation area is greater than 256K and less than 1024K, and the capacity range of the z.zone hard disk hibernation area is greater than 1024K.

[0088] When pre-storing, first, the capacity of initial storage data is determined; the granularity of the capacity can be expressed in byte units.

[0089] In sub-step S2032, when the capacity of initial storage data is in the capacity range, the hard disk hibernation area corresponding to the capacity range is determined as the initial hard disk hibernation area.

[0090] The capacity of initial storage data is compared with the capacity range corresponding to each hard disk hibernation area, to determine the capacity range to which the initial storage data belongs; when the capacity of initial storage data is in the capacity range, the hard disk hibernation area corresponding to the capacity range is determined as the initial hard disk hibernation area.

[0091] Continuing with the above example, when the initial storage data is less than 16K, the a.zone hard disk hibernation area is determined as the initial hard disk hibernation area; when the initial storage data is greater than 16K and less than 256K, the b.zone hard disk hibernation area is determined as the initial hard disk hibernation area; when the initial storage data IO is greater than 256K and less than 1024K, the c.zone hard disk hibernation area is determined as the initial hard disk hibernation area; and when the initial storage data is greater than 1024K, the z.zone hard disk hibernation area is determined as the initial hard disk hibernation area.

[0092] In sub-step S2033, the initial storage data is stored in the initial hard disk hibernation area.

[0093] The initial storage data is stored in the initial hard disk hibernation area, to complete the pre-storing of the initial storage data, and wait for the data analysis period to determine the read frequency.

[0094] In step 204, when a read request for the initial storage data is received, a current timestamp is obtained, and the current timestamp is added to the initial storage data to generate target storage data.

[0095] When the initial storage data is stored in the initial hard disk hibernation area, when a read request for the initial storage data is received, a current timestamp can be obtained; and the current timestamp is added to the initial storage data to generate target storage data. The way of obtaining the current timestamp can be set according to requirements by those skilled in the art, and the embodiments of the present application do not limit this.

[0096] In addition, when the target storage data is generated, when a new read request for the initial storage data is received, a new current timestamp is obtained, and the new current timestamp is used to update the current timestamp in the target storage data.

[0097] Step 205, starting a preset data analysis period, generating a frequency label corresponding to the target storage data based on the starting time data of the preset data analysis period and the target storage data;

[0098] Starting a preset data analysis period, performing data analysis on the initial storage data based on the starting time data of the preset data analysis period, determining the reading frequency of the target storage data, and generating a frequency label corresponding to the target storage data.

[0099] Specifically, the starting time data of the preset data analysis period includes a starting time stamp and a period length, and the step of generating a frequency label corresponding to the target storage data based on the starting time data of the preset data analysis period and the target storage data can include the following sub-steps:

[0100] Sub-step S2051, comparing the starting time stamp with the current time stamp corresponding to the target storage data to generate a time difference;

[0101] In an embodiment of the present application, the starting time data of the preset data analysis period includes a starting time stamp and a period length. The starting time stamp is the time stamp of starting the preset data analysis period. The starting time stamp and the current time stamp of the target storage data are on the same time axis. The period length is the length of the running of the preset data analysis period.

[0102] First, the starting time stamp can be compared with the current time stamp corresponding to the target storage data. The time difference (t.diff) can be generated by subtracting the current time stamp (t.read) from the starting time stamp (t.real). The maximum value of t.diff should be the period length, and the minimum value is 0. When t.read is greater than t.real, t.diff is directly marked as 0.

[0103] Sub-step S2052, determining a frequency label corresponding to the target storage data according to the time difference and the period length.

[0104] According to the relationship between the time difference and the period length, the frequency label corresponding to the target storage data is determined.

[0105] In an optional embodiment of the present application, the step of determining a frequency label corresponding to the target storage data according to the time difference and the period length includes the following sub-steps:

[0106] Sub-step S20521, dividing the period length into a plurality of equal reference lengths, and the reference length corresponds to a frequency label;

[0107] In the embodiment of the present application, the period length can be divided into multiple equal-difference reference lengths according to the relationship between the time difference and the period length; for example, 25% of the period length is the first reference length, 50% of the period length is the second reference length, 75% of the period length is the third reference length, and 100% of the period length is the fourth reference length.

[0108] In sub-step S20522, the target reference length is determined from the reference lengths according to the time difference.

[0109] The target reference length is determined from the reference lengths according to the size of the time difference. Continuing with the above example, when the time difference is less than 25% of the period length, the first reference length is determined as the target reference length; when the time difference is less than 50% of the period length and greater than 25% of the period length, the second reference length is determined as the target reference length; when the time difference is less than 75% of the period length and greater than 50% of the period length, the third reference length is determined as the target reference length; and when the time difference is greater than 75% of the period length, the fourth reference length is determined as the target reference length.

[0110] In sub-step S20523, the frequency label corresponding to the target reference length is determined as the frequency label corresponding to the target storage data.

[0111] Each reference length represents a different reading frequency, and the frequency label corresponding to each reference length represents a different reading frequency. Continuing with the above example, the reading frequencies represented by the first reference length, the second reference length, the third reference length, and the fourth reference length are increasing, i.e., the reading frequency corresponding to the first reference length < the reading frequency corresponding to the second reference length < the reading frequency corresponding to the third reference length < the reading frequency corresponding to the fourth reference length. Accordingly, the reading frequency of the frequency label corresponding to the target reference length is also the same.

[0112] After the target reference length is determined, the frequency label corresponding to the target reference length can be determined as the frequency label corresponding to the target storage data.

[0113] In an optional embodiment of the present application, the step of determining the frequency label corresponding to the target storage data according to the time difference and the period length comprises the following sub-steps:

[0114] In sub-step S20524, the ratio of the time difference to the period length is calculated.

[0115] In the embodiment of the present application, another embodiment for determining the frequency label corresponding to the target storage data is provided. The start time data of the preset data analysis period comprises a start time stamp and a period length. The start time stamp is the time stamp of starting the preset data analysis period. The start time stamp and the current time stamp of the target storage data are in the same time axis. The period length is the length of running the preset data analysis period.

[0116] Firstly, the ratio of the time difference to the period length is calculated, i.e. the proportion of the time difference in the period length.

[0117] In sub-step S20525, the target storage data is sorted based on the ratio.

[0118] The target storage data is sorted based on the size relationship of the ratio. The sorting can be sequential sorting or reverse sorting.

[0119] In sub-step S20526, the frequency label corresponding to the target storage data is determined according to the sorting position of the target storage data.

[0120] After sorting, the reading frequency level of the target storage data is determined according to the sorting position of the target storage data, and then the frequency label corresponding to the target data is determined. For example, if there are 10 data, and the sorting position of the target storage data in the sequential sorting is the second, it can be determined that the frequency label corresponding to the target storage data is the high-frequency label.

[0121] In step 206, the target hard disk hibernation area is determined according to the frequency label, and the target hard disk hibernation area is different from the hibernation depth of the initial hard disk hibernation area.

[0122] The target hard disk hibernation area with matching reading frequency is determined from the divided hard disk hibernation area according to the frequency label, and the target hard disk hibernation area is different from the hibernation depth of the initial hard disk hibernation area.

[0123] In step 207, after the end of the current cycle period, the initial storage data is moved from the initial hard disk hibernation area to the target hard disk hibernation area.

[0124] After the end of the current cycle period, i.e. after the completion of all data analysis, the initial storage data can be moved from the initial hard disk hibernation area to the target hard disk hibernation area for storage, and follow the hibernation rhythm of the target hard disk hibernation area for hibernation.

[0125] In an optional embodiment of the present application, the step of moving the initial storage data from the initial hard disk hibernation area to the target hard disk hibernation area can comprise the following sub-steps:

[0126] Sub-step S2071, reading the initial storage data from the initial hard disk hibernation area;

[0127] In practical applications, the initial storage data can be read from the initial hard disk hibernation area first.

[0128] Sub-step S2072, storing the initial storage data to the idle storage hard disk of the target hard disk hibernation area;

[0129] The read initial storage data is stored in the idle storage hard disk of the target hard disk hibernation area, so as to realize the storage of the initial storage data.

[0130] Specifically, the step of storing the initial storage data to the idle storage hard disk of the target hard disk hibernation area specifically includes the following sub-steps:

[0131] Sub-step S20721, sequentially storing the initial storage data to the idle storage hard disk of the target hard disk hibernation area one by one.

[0132] In practical applications, the next idle storage hard disk can be determined based on the currently used storage disk of the target hard disk hibernation area, the initial storage data is sequentially stored in the next idle storage hard disk one by one, and the first idle storage hard disk of the target hard disk hibernation area is sequentially written to the next idle storage hard disk.

[0133] Sub-step S2073, deleting the initial storage data from the initial hard disk hibernation area.

[0134] After reading the initial storage data, the initial storage data can be deleted from the initial hard disk hibernation area, so as to avoid repeated storage and improve the storage rate of the initial hard disk hibernation area.

[0135] Step 208, detecting the frequency baseline value of each divided hard disk hibernation area;

[0136] After the initial storage data is stored into the target hard disk hibernation area, the frequency baseline value of the entire divided hard disk hibernation area can be detected. The frequency baseline value is the ratio of the total number of the storage hard disks divided into the hard disk hibernation area to the number of the currently used storage hard disks. For example, the frequency baseline value rate.a of the a.zone hard disk hibernation area is the number of the disks in the current area / the number of the currently used disks. The frequency baseline value rate.b of the b.zone hard disk hibernation area is the number of the disks in the current area / the number of the currently used disks. The frequency baseline value rate.c of the c.zone hard disk hibernation area is the number of the disks in the current area / the number of the currently used disks. The frequency baseline value rate.z of the z.zone hard disk hibernation area is the number of the disks in the current area / the number of the currently used disks.

[0137] Step 209, the frequency baseline values are sorted in reverse order to generate a frequency sequence.

[0138] The frequency baseline values are sorted in reverse order according to the size to generate a frequency sequence; that is, the elements in the frequency sequence decrease.

[0139] Step 210, the frequency difference value between the first frequency baseline value and the last frequency baseline value in the frequency sequence is calculated.

[0140] The first frequency baseline value and the last frequency baseline value in the frequency sequence are determined, the maximum value in the frequency sequence, that is, max(rate.a., rate.b, rate.c, rate.z), and the minimum value in the frequency sequence, that is, min(rate.a., rate.b, rate.c, rate.z), are taken. The frequency difference value between the first frequency baseline value and the last frequency baseline value is calculated, that is, max(rate.a., rate.b, rate.c, rate.z)-min(rate.a., rate.b, rate.c, rate.z).

[0141] Step 211, the ratio of the frequency difference value to the last frequency baseline value is calculated.

[0142] The ratio of the frequency difference value to the last frequency baseline value is calculated, that is, (max(rate.a., rate.b, rate.c, rate.z)-min(rate.a., rate.b, rate.c, rate.z)) / min(rate.a., rate.b, rate.c, rate.z); the difference of the use of the storage hard disks divided into the hard disk hibernation area is determined by the ratio.

[0143] Step 212, when the ratio is greater than a preset adjustment threshold, the storage hard disk of the last frequency baseline value corresponding to the divided hard disk sleep area is reduced, and the storage hard disk of the first frequency baseline value corresponding to the divided hard disk sleep area is increased.

[0144] When the ratio is greater than a preset adjustment threshold, it indicates that the use of the storage hard disk of the divided hard disk sleep area is not balanced, and the storage hard disk of the first frequency baseline value corresponding to the divided hard disk sleep area can be increased, and the storage hard disk of the last frequency baseline value corresponding to the divided hard disk sleep area can be reduced, so that the use of the storage hard disk of each divided hard disk sleep area is balanced. The preset adjustment threshold can be selected according to the actual situation, and the embodiment of the application is not limited to this. In an example of the application, the preset adjustment threshold can be 25%.

[0145] By pre-judging the initial storage data to fall into the corresponding sleep area, then storing the initial storage data into the target hard disk sleep area matching the reading frequency based on the use frequency of the initial storage data, the hard disk in shallow sleep can be frequently awakened, avoiding the hard disk in deep sleep from being frequently awakened, achieving the purpose of reducing the overall power consumption; and after storing the initial storage data into the target hard disk sleep area, judging the use of each divided hard disk sleep area, adjusting the number of storage hard disks of the divided hard disk sleep area, so that the hard disk sleep area can have sufficient storage space to store data, avoiding storing data into the divided hard disk sleep area that does not match the reading frequency, further improving the accuracy of storage, so that data can be stored in the divided hard disk sleep area with appropriate reading frequency, and the divided hard disk sleep area can be effectively put into sleep, further reducing the overall energy consumption.

[0146] In order for those skilled in the art to better understand the embodiments of the application, the embodiments of the application are described below by an example:

[0147] Referring to Figure 3 , a step flow chart of an example of a data storage management method of the application is shown;

[0148] First, when the hard disk is in sleep state, the hard disk sleep area is divided based on the address of the current hard disk, and the total number of 60 disks is divided according to the number ratio of 1:2:3:4, i.e. a.zone, b.zone, c.zone, z.zone disks, and the corresponding number is 6, 12, 18, and 24 respectively.

[0149] After receiving 300K (byte) size data, it is judged that the data is based on size, greater than 56K and less than 1024K, i.e. can fall into idleC area (initial hard disk sleep area), and is written into the first disk of C area.

[0150] Receive 800K size data, judge data based on size, greater than 56K and less than 1024K, that is, can fall into idleC area (initial hard disk hibernation area), fall into the first piece of disk. If the first piece of disk space is full, fall into the second piece of disk.

[0151] When there is a read request for 300K data, add the tag t.real (current timestamp).

[0152] When there is a read request for 300K data again, update the tag t.real.

[0153] Select t.cycle (current cycle) as 4 days.

[0154] Because 300K data has more frequent reading, time period confirmation is performed, diff (time difference) is 0.5, and the target hard disk hibernation area is determined as a.zone area.

[0155] Because 800K data falls into C disk and has no reading, time period confirmation diff is 4, and the target hard disk hibernation area is determined as z.zone area.

[0156] After the current cycle period ends, move 300K data to a.zone area and start storing from the disk of the current area. If the first piece of disk is full, store it in the second piece of disk in turn. Move 800K data to z.zone area and start storing from the disk of the current area. If the first piece of disk is full, store it in the second piece of disk in turn.

[0157] After the identification is completed, start moving data to the idle storage hard disk of the target hard disk hibernation area, complete the allocation of data in the current cycle period, and enter the hibernation state of the corresponding area based on the area.

[0158] When there is a data read request, the hard disk can be awakened in any area and respond to the data read request.
