Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a data storage management method according to the present invention is shown, where the data storage management method may specifically include the following steps:
when data of the storage hard disk is needed, the data needing to be stored, namely initial storage data, can be acquired. The initial storage data may 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 temperature data; the hot data refers to online data which is frequently accessed, and the requirement on storage performance is high. Cold data refers to offline type data that is not accessed frequently, such as backup and archive data. The storage performance requirements are relatively low, requiring a mass storage medium. The access frequency of the warm data and the requirement on the storage performance are between those of the hot data and the cold data.
after the initial storage data is acquired, the initial storage data can be judged based on the capacity of the initial storage data, an initial hard disk dormant area matched with the capacity of the initial storage data is determined, and the initial storage data is stored in the initial hard disk dormant area to be prestored based on the capacity of the initial storage data.
It should be noted that there may be a plurality of initial hard disk hibernation areas, and different initial hard disk hibernation areas are used for storing initial storage data with different capacities. By way of example, there may be four initial hard disk hibernation regions: a.zone dormant zone, b.zone dormant zone, c.zone dormant zone, z.zone dormant zone. Zone is used for initial storage data with a storage capacity less than 16K (bytes); the zone dormant area is used for storing initial storage data with the capacity larger than 16K and smaller than 256K; the zone dormant area is used for storing initial storage data with the capacity larger than 256K and smaller than 1024K; the zone dormant region is used for initial storage data with a storage capacity larger than 1024K.

after the initial storage data is pre-stored in the initial hard disk hibernation area, there may be a read request for the initial storage data. The method can receive a read request of the initial storage data, and respond to the read request to read the initial storage data from the initial hard disk dormant area; meanwhile, a current timestamp corresponding to the current actual time can be obtained, such as 14; and adding the current time stamp to the initial storage data to generate target storage data, namely the target storage data is the storage data carrying the current time stamp.
In addition, when a read request of the initial storage data is received after the target storage data is generated, a new current timestamp may be acquired, and the current timestamp in the target storage data may be updated.
It should be noted that the granularity of the current timestamp may be minutes, seconds, milliseconds, microseconds, etc., and the granularity of the timestamp is not limited.
when target storage data need to be analyzed to determine the reading frequency, starting a preset data analysis period; and analyzing the reading frequency of the target storage data by starting a preset data analysis period. And determining a frequency tag corresponding to the reading frequency of the target storage data according to the difference between the starting time data of the preset data analysis period and the target storage data. The frequency tag is used for representing the reading frequency grade of target storage data; as the frequency signature may be, A, B, C, D; the frequency grade of the grade A is the reading frequency; the frequency grade of the grade B is general frequency; the frequency grade of the grade C is less reading; the frequency of the D level is not read.
In addition, in order to avoid influencing other running processes in the data analysis process, the data analysis process can be carried out at the time of the low valley value of the equipment data processing. Data analysis was performed as 24h data low in the morning.
105, determining a target hard disk sleeping area according to the frequency tag, wherein the sleeping depth of the target hard disk sleeping area is different from that of the initial hard disk sleeping area;
the frequency tags correspond to hard disk dormant areas with different reading frequencies, and after the frequency tag corresponding to the target storage data 5 is determined, the corresponding hard disk dormant area is determined as a target hard disk according to the frequency tag
A sleeping area. The target hard disk dormant area and the initial hard disk dormant area have different dormant depths; and the physical hard disks corresponding to the target hard disk dormant area and the initial hard disk dormant area can be the same, namely, the target hard disk dormant area and the initial hard disk dormant area are dormant areas corresponding to the same physical hard disk in different stages.
And 106, after the current cycle period is finished, moving the initial storage data from the initial 0 hard disk hibernation area to the target hard disk hibernation area.
When the current cycle period of data analysis is finished, the data can be moved. At this time, the target hard disk dormant area determined by the initial storage data according to the frequency tag can be moved from the originally stored initial hard disk dormant area to the target hard disk dormant area; dormancy for storing initial storage data in target hard disk
And entering the target hard disk sleep area to sleep, so that the data with the same reading frequency grade can be stored in the same 5 target hard disk sleep areas, the data reading frequency in one target hard disk sleep area is the same, more sleep time can be obtained, and the power consumption of the hard disk can be reduced.
The embodiment of the invention obtains the initial storage data; storing the initial storage data to an initial hard disk dormant area matched with the capacity of the initial storage data; upon receiving a request for the initial storage
When a data reading request is made, acquiring a current time stamp, adding the current time 0 stamp to the initial storage data, and generating target storage data; starting a preset data analysis period, and generating a frequency tag corresponding to the target storage data based on starting time data of the preset data analysis period and the target storage data; determining a target hard disk sleeping area according to the frequency tag, wherein the sleeping depth of the target hard disk sleeping area is different from that of the initial hard disk sleeping area; after the current cycle period is finished, the current cycle period is ended
And the initial storage data is moved from the initial hard disk dormant area to the target hard disk dormant area. Pre-judging 5 initial storage data to fall into a corresponding dormant area; and then storing the initial storage data into a target hard disk sleeping area matched with the reading frequency based on the use frequency of the initial storage data, wherein the hard disk in shallow sleep can be frequently awakened, the hard disk in deep sleep is prevented from being frequently awakened, and the aim of reducing the whole power consumption is fulfilled.
Referring to fig. 2, a flowchart illustrating steps of another embodiment of a data storage management method according to the present invention is shown, where the data storage management method may specifically include the following steps:
when the hard disk is in a dormant state, data in the hard disk cannot be read and written, at the moment, the dormant area can be divided by the address of the hard disk, and a plurality of hard disk dormant areas are divided based on the area corresponding to the address. Different partition hard disk dormant areas are used for storing data with different capacities or different reading frequencies. Each divided hard disk dormant area is provided with a plurality of storage hard disks; because the stored data capacity is different, the corresponding capacity, namely the number of the storage hard disks, can be different; and the storage hard disks in the divided hard disk sleeping areas can be numbered so as to conveniently identify the storage hard disks.
For example, based on the hibernation state of the hard disk, an a.zone hard disk hibernation area, a b.zone hard disk hibernation area, a c.zone hard disk hibernation area, and a z.zone hard disk hibernation area are divided according to the address area.
The storage hard disk in the area of the entry to a.zone is numbered, n1.azone … … nx.azone. The storage hard disk entering the zone of b.zone is numbered, n1.Bzone … … nx. The storage hard disk in the zone that entered c.zone is numbered, n1.Czone … … nx.czone. The storage hard disk in the zone of the incoming z.zone is numbered, n1.Zzone … … nx.zzone. The number of the storage hard disks corresponding to the a.zone hard disk sleeping area, the b.zone hard disk sleeping area, the c.zone hard disk sleeping area and the z.zone hard disk sleeping area can specifically meet the following requirements: 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 may be dynamically adjusted subsequently based on the use condition.
after the hard disk sleep area is divided, when an Input/Output (IO) arrives each time, initial storage data carried by the IO is acquired.
in the embodiment of the invention, the divided hard disk dormant area is the initial hard disk dormant area when the initial storage data is prestored. After the initial storage data is received, the initial storage data can be stored into the matched initial hard disk dormant area according to the capacity of the initial storage data.
Specifically, the plurality of divided hard disk hibernation regions correspond to different capacity ranges, and the step of storing the initial storage data into an initial hard disk hibernation region matching the capacity of the initial storage data may include the following sub-steps:
substep S2031, determining the capacity of the initial storage data;
in practical application, different divided hard disk dormant areas, namely different initial hard disk dormant areas, correspond to different capacity ranges; for example, the capacity range of the zone hard disk sleeping area is less than 16K, the capacity range of the b.zone hard disk sleeping area is more than 16K and less than 256K, the capacity range of the c.zone hard disk sleeping area is more than 256K and less than 1024K, and the capacity range of the z.zone hard disk sleeping area is more than 1024K.
When pre-storing, firstly determining the capacity of initial storage data; the granularity of the capacity can be expressed in bytes.
Substep S2032, when the capacity of the initial storage data is within the capacity range, determining a divided hard disk hibernation area corresponding to the capacity range as the initial hard disk hibernation area;
comparing the capacity of the initial storage data with the capacity range corresponding to each hard disk dormant area, and determining the capacity range to which the capacity of the initial storage data belongs; and when the capacity of the initial storage data is within the capacity range, determining the hard disk dormant area corresponding to the capacity range as the pre-stored initial hard disk dormant area.
Continuing with the above example: when the initial storage data is smaller than 16K, determining the a.zone hard disk sleep area as an initial hard disk sleep area; and when the initial storage data is more than 16K and less than 256K, determining that the b.zone hard disk sleep area is the initial hard disk sleep area. And when the initial storage data IO is larger than 256K and smaller than 1024K, determining that the zone hard disk sleep area is the initial hard disk sleep area. And when the initial storage data is more than 1024K, determining the z.zone hard disk sleep area as the initial hard disk sleep area.
And a substep S2033 of storing the initial storage data into the initial hard disk hibernation area.
And storing the initial storage data into an initial hard disk sleep area to finish pre-storing the initial storage data, and waiting for a data analysis period to determine the reading frequency of the initial storage data.
after storing into the initial hard disk hibernation area, when receiving a read request for initial storage data, acquiring a current timestamp; and adding the current time stamp to the initial storage data to generate target storage data. The method for obtaining the current timestamp may be set by a person skilled in the art according to a requirement, and is not limited in the embodiment of the present invention.
In addition, after the target storage data is generated, when a new read request for the initial storage data is received, a new current timestamp is acquired, and the current timestamp in the target storage data is updated with the new current timestamp.
starting a preset data analysis period, carrying out 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 tag corresponding to the target storage data.
Specifically, the starting time data of the preset data analysis period includes a starting timestamp and a period duration, and the step of generating the frequency tag corresponding to the target storage data based on the starting time data of the preset data analysis period and the target storage data may include the following sub-steps:
substep S2051, comparing the starting timestamp with the current timestamp corresponding to the target storage data, and generating a time difference;
in the embodiment of the present invention, the start time data of the preset data analysis period includes a start time stamp and a period duration. And the starting time stamp is the time stamp for starting the preset data analysis period. The start time stamp is on the same time axis as the current time stamp of the target stored data. The period duration is the duration of the operation of the preset data analysis period.
First, the start time stamp may be compared with a current time stamp corresponding to the target storage data, and the time difference (t.diff) may be generated by subtracting the current time stamp (t.read) from the start time stamp (t.real). The maximum value of the t.diff value is the period duration, and is 0 in the shortest. When t.read is greater than t.real, the direct flag t.diff is 0.
And a substep S2052 of determining a frequency tag corresponding to the target storage data according to the time difference and the period duration.
And determining a frequency tag corresponding to the target storage data according to the relation between the time difference and the period duration.
In an optional embodiment of the present invention, the step of determining, according to the time difference and the period duration, a frequency tag corresponding to the target storage data includes the following sub-steps:
in the substep S20521, dividing the period duration into a plurality of equal-difference reference durations, wherein the reference durations correspond to frequency labels;
in the embodiment of the invention, aiming at the relation between the time difference and the period duration, the period duration can be divided into a plurality of equal-difference reference durations; for example, the 25% cycle duration is the first reference duration, the 50% cycle duration is the second reference duration, the 75% cycle duration is the third reference duration, and the 100% cycle duration is the fourth reference duration.
A substep S20522 of determining a target reference duration from the reference durations according to the time difference;
and determining the target reference time length from the reference time length according to the reference time length to which the time difference belongs. Continuing with the above example: when the time difference is less than 25% of the period duration, determining the first reference duration as a target reference duration; the time difference is less than 50% of the period duration, and the second reference duration which is more than 25% of the period duration is determined as the target reference duration; the time difference is less than 75% of the period duration, and a third reference duration which is greater than 50% of the period duration is determined as a target reference duration; and determining the fourth reference time length as the target reference time length when the time difference is greater than 75% of the cycle time length.
And a substep S20523, determining the frequency tag corresponding to the target reference time length as the frequency tag corresponding to the target storage data.
Each reference time length represents different reading frequencies and corresponds to frequency tags of the different reading frequencies. Continuing with the above example: the reading frequencies represented by the first reference time length, the second reference time length, the third reference time length and the fourth reference time length are increased in an increasing mode, namely the reading frequency corresponding to the first reference time length is smaller than the reading frequency corresponding to the second reference time length and smaller than the reading frequency corresponding to the third reference time length and smaller than the reading frequency corresponding to the fourth reference time length. Accordingly, the reading frequency of the frequency tag corresponding to the target reference time length is also the same.
After the target reference time length is determined, it may be determined that the frequency tag corresponding to the target reference time length is a frequency tag corresponding to the target storage data.
In an optional embodiment of the present invention, the step of determining the frequency tag corresponding to the target storage data according to the time difference and the period duration includes the following sub-steps:

in the embodiment of the present invention, another embodiment for determining a frequency tag corresponding to target storage data is provided. The start time data of the preset data analysis period comprises a start time stamp and a period duration. And the starting time stamp is the time stamp for starting the preset data analysis period. The start time stamp is on the same time axis as the current time stamp of the target stored data. The period duration is the duration of the operation of the preset data analysis period.
First, the ratio of the time difference to the cycle duration, i.e., the ratio of the time difference to the cycle duration, is calculated.
Substep S20525, sorting the target storage data based on the ratio;
sorting the target storage data based on the magnitude relation of the ratios; the ordering may be sequential ordering or reverse ordering.
And a substep S20526 of determining a frequency tag corresponding to the target storage data according to the sorting position of the target storage data.
After sorting, according to the sorting position of the target storage data, determining the reading frequency grade of the target storage data, and further determining the frequency tag corresponding to the target data. If there are 10 data, the current target storage data is ranked second in the sequence ranking, and the frequency tag corresponding to the target storage data can be determined to be a high-frequency tag.
and determining a target hard disk sleeping area matched with the reading frequency from the divided hard disk sleeping areas according to the frequency tag, wherein the sleeping depth of the target hard disk sleeping area is different from that of the initial hard disk sleeping area.
after the current cycle period is finished, that is, after all data analysis is finished, the initial storage data can be moved from the initial hard disk sleeping area to the target hard disk sleeping area for storage, and the data can sleep along with the sleeping rhythm of the target hard disk sleeping area.
In an optional embodiment of the present invention, the step of moving the initial storage data from the initial hard disk hibernation area to the target hard disk hibernation area may include the following sub-steps:
substep S2071, reading the initial storage data from the initial hard disk hibernation area;
in practical application, the initial storage data may be read from the initial hard disk hibernation area first.

and storing the read initial storage data into an idle storage hard disk in the target hard disk dormant area to realize the storage of the initial storage data.
Specifically, the step of storing the initial storage data to the idle storage hard disk in the target hard disk hibernation area specifically includes the following sub-steps:
and a substep S20721, sequentially storing the initial storage data one by one to an idle storage hard disk in the target hard disk dormant area.
In practical application, the next free storage hard disk can be determined based on the currently used storage disk of the target hard disk hibernation area; storing the initial storage data into the next idle storage hard disk one by one; and writing the first idle storage hard disk in the target hard disk sleep area into the next idle storage hard disk one by one.
And a substep S2073 of deleting the initial storage data from the initial hard disk hibernation area.
After the initial storage data are read, the initial storage data can be deleted from the initial hard disk dormant area, so that repeated storage is avoided, and the storage rate of the initial hard disk dormant area is improved.
208, detecting a frequency baseline value of each divided hard disk sleep area;
after the initial storage data is stored in the target hard disk sleep area, the frequency baseline value of all the divided hard disk sleep areas can be detected. The frequency baseline value is the ratio of the total number of the storage hard disks for dividing the hard disk sleep area to the number of the storage hard disks which are used currently. If the frequency base line value rate.a is determined in the a.zone hard disk sleep area, the value of rate.a is the number of disks in the area currently/the number of disks which are used currently. And determining a frequency base line value rate.b in the zone hard disk sleep area, wherein the value of rate.b is the number of disks in the zone/the number of disks which are used currently. And determining a frequency base line value rate.c in the c.zone hard disk sleep area, wherein the value of rate.c is the number of disks in the area/the number of disks which are used currently. And determining a frequency base line value rate.z in a z.zone hard disk sleep area, wherein the value of rate.c is the number of disks in the area/the number of disks which are used currently.
performing reverse sequencing according to the magnitude of the frequency baseline value to generate a frequency sequence; i.e. the elements in the frequency sequence are decremented.
determining the first frequency baseline value and the last frequency baseline value from the frequency sequence, and taking the maximum value in the frequency sequence, namely max (rate.a., rate.b., rate.c., rate.z), and the minimum value in the frequency sequence, namely min (rate.a., rate.b., rate.c., rate.z). And calculating the frequency difference value between the first frequency baseline value and the last frequency baseline value, namely calculating max (rate.a., rate.b., rate.c., rate.z) -min (rate.a.), rate.b., rate.c., rate.z).
calculating the ratio of the frequency difference value to the last frequency baseline value, namely (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); and determining the difference of the use conditions of the storage hard disks of the divided hard disk sleep areas according to the ratio.
And 212, when the ratio is greater than a preset adjustment threshold, reducing the storage hard disk of the hard disk sleep area division corresponding to the last frequency baseline value, and correspondingly increasing the storage hard disk of the hard disk sleep area division corresponding to the first frequency baseline value.
When the ratio is greater than the preset adjustment threshold, the condition that the use conditions of the hard disks in the hard disk sleep areas are unbalanced is indicated, the hard disks in the hard disk sleep areas corresponding to the first frequency baseline value can be correspondingly increased, and the hard disks in the hard disk sleep areas corresponding to the last frequency baseline value can be reduced, so that the use conditions of the hard disks in the hard disk sleep areas are balanced. The preset adjustment threshold may be selected according to actual conditions, which is not limited in the embodiment of the present invention. In one example of the present invention, the preset adjustment threshold may be 25%.
Pre-judging initial storage data to fall into a corresponding dormant region; then storing the initial storage data into a target hard disk sleeping area matched with the reading frequency based on the use frequency of the initial storage data, wherein the hard disk in shallow sleep can be frequently awakened, the hard disk in deep sleep is prevented from being frequently awakened, and the purpose of reducing the overall power consumption is achieved; and after the initial storage data is stored in the target hard disk dormant area, the using condition of each divided hard disk dormant area is judged, the quantity of the storage hard disks in the divided hard disk dormant areas is adjusted, so that the hard disk dormant areas can have sufficient storage space to store the data, the data is prevented from being stored in the divided hard disk dormant areas which are not matched with the reading frequency, the storage accuracy is further improved, the data can be stored in the divided hard disk dormant areas with the proper reading frequency, the divided hard disk dormant areas can be effectively dormant, and the overall energy consumption is further reduced.

And if the space of the first disc is full, the first disc falls into the second disc.
When there is a read request for 300K of data, the tag t.
The tag t.real is updated when there is again a read request for 300K.
Cycle (current cycle) was chosen to be 4 days.
And because the 300K data is read more frequently, the time period confirmation is carried out, diff (time difference) is 0.5, and the target hard disk sleep area is determined to be an a.zone area.
And determining that diff is 4 after the 800K data fall into the C disk and are not read, and determining that the target hard disk sleep area is a z.zone area.
After the current cycle period ends, the 300K data is moved to the a.zone area, and the storage is started from the disk of the current area. If the first disk is full, the first disk is stored in the second disk in sequence. The 800K data is moved to the z.zone area and stored from the disk of the current area. If the first disk is full, the first disk is stored in the second disk in sequence.
And after the identification is finished, starting the data to move to the idle storage hard disk in the target hard disk dormant area, and after the distribution of the data in the current cycle period is finished, entering the dormant state of the corresponding area based on the area in which the data is located.
