Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for detecting a storage capacity of a storage device according to an embodiment of the present disclosure. The method comprises the following steps:
step 11: and obtaining first detection time according to the type of the data to be written.
In this embodiment, the storage device may be a hard disk, such as a mechanical hard disk or a solid state hard disk. The storage device may also be a usb disk.
When data is written into the storage device, because the size of data generated in a certain time is different for each type of data, different weights can be set for the data to be written of different data types, and the corresponding first detection time can be obtained according to the weights.
The first detection time is used for indicating the detection frequency of the storage capacity of the storage device when the data to be written is written into the storage device. If the first detection time is 10 minutes, the storage capacity of the storage device is detected 10 minutes after the data to be written is written into the storage device.
Step 12: and after the first detection time is up, obtaining the first storage capacity of the data to be written in the storage device so as to obtain the second storage capacity occupied in the storage device.
The first storage capacity is the data size of the data to be written in the storage device in the first detection time. The second storage capacity is the second storage capacity currently occupied by the storage device. The second storage capacity is almost equal to the first storage capacity when the storage device is first used, and is larger than the first storage capacity in other cases.
Step 13: and updating the first detection time according to the second storage capacity.
In some embodiments, a capacity class corresponding to the second storage capacity may be determined, and the first detection time may be updated according to the capacity class.
For example, the capacity ranks of the storage device are divided by percentage, with thirty-five percent or less being the capacity rank a, thirty-five percent to seventy percent being the capacity rank B, and seventy percent or more being the capacity rank C. Corresponding values are set for different capacity classes, e.g. capacity class a is set to a value of 1, capacity class B is set to a value of 2, and capacity class C is set to a value of 3. And dividing the first detection time by the numerical value of the capacity grade corresponding to the second storage capacity to obtain second detection time. The second detection time may be used as a new first detection time. Specifically, when the numerical value of the capacity rank corresponding to the second storage capacity is 1 or 2, the second detection time is obtained by dividing the first detection time by the numerical value of the capacity rank corresponding to the second storage capacity. And when the numerical value of the capacity grade corresponding to the second storage capacity is 3, deleting part of data in the storage device to release the storage capacity. The data with the oldest writing time may be deleted according to the writing time of the data.
In an application scenario, after determining data to be written, a first detection time can be obtained according to the type of the data to be written. And after the first detection time is up, obtaining the first storage capacity of the data to be written in the storage device so as to obtain the second storage capacity occupied in the storage device. And determining the capacity grade of the second storage capacity, correspondingly updating corresponding first detection time, and continuing to execute the steps if the type of the data to be written is not changed after the first detection time is up. When the occupation ratio of the second storage capacity in the storage device is larger than a set threshold, performing data aging of the storage device to delete part of the data.
In this embodiment, the detection time is dynamically updated by using the type of the data to be written and the storage capacity of the storage device, so that the detected storage capacity of the storage device better meets the actual situation, and on the premise of meeting the read-write requirement of the existing task on the storage device, the read-write operation on the storage device is reduced, the damage to the storage device caused by long-term frequent read-write is reduced, the service life of a hard disk is prolonged, and the waste of system resources is reduced.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a method for detecting a storage capacity of a storage device according to another embodiment of the present disclosure. The method comprises the following steps:
step 21: and acquiring a first weight corresponding to the type of the data to be written.
When the data to be written includes multiple types, weighting may be performed according to the first weight corresponding to each type to obtain an average weight value, and the average weight value is used as the first weight of the data to be written.
Step 22: and obtaining a first detection time by using the first weight and the standard detection time.
If the first weight is 0.8 and the standard detection time is 30 minutes, the first detection time is 0.8 × 30 — 24 minutes. It will be appreciated that different standard test times may be set depending on the overall capacity of the storage device.
Step 23: and after the first detection time is up, obtaining the first storage capacity of the data to be written in the storage device so as to obtain the second storage capacity occupied in the storage device.
Step 24: and calculating by using the first detection time and the first storage capacity to obtain the writing speed of the data to be written when the data is written into the storage device.
Since the first detection time and the first storage capacity are known, the writing speed of the data to be written in the first detection time can be calculated.
In some embodiments, referring to fig. 3, step 24 may specifically be the following step:
step 241: and acquiring the sequence number of the current first detection time.
In an embodiment, the first detection times are sorted each time, and the first detection times each time have corresponding sequence numbers.
Step 242: if the serial number is smaller than the preset serial number, the writing speeds corresponding to the serial number and a plurality of first detection times before the serial number are obtained respectively.
Step 243: calculating an average value of a plurality of writing speeds; the average value is taken as the writing speed.
It can be understood that when the sequence number is smaller than the preset sequence number, the storage device is indicated to write data less times. The number and the write speeds corresponding to the previous times are averaged, and the average value is taken as the write speed. If the preset number is 4, the writing speed is obtained from the corresponding first storage capacity and the first detection time when the number is 1, and at this time, the average value is not required because the number is 1. When the number is 2, the writing speed is obtained from the first storage capacity and the first detection time corresponding thereto, and the writing speed corresponding to the number 1, and the average value of the two writing speeds is obtained as the writing speed. At the time of number 3, the write speed is obtained from the corresponding first storage capacity and first detection time, and the write speeds corresponding to numbers 1 and 2, and the average of the three write speeds is obtained as the write speed. When the serial number is 4, the serial number is equal to the preset serial number, and the writing speed is obtained according to the corresponding first storage capacity and the first detection time. And if the serial number is greater than the preset serial number, calculating the writing speed according to the corresponding first storage capacity and the first detection time. And when the sequence number is greater than or equal to the preset sequence number, the obtained writing speed is greater than the previous writing speed, the current writing speed is used for updating the previous writing speed, and when the writing time is calculated again, the updated writing speed is used.
Step 25: and calculating by using the third storage capacity and the second storage capacity of the storage device to obtain a fourth storage capacity.
Wherein the third storage capacity is a total storage capacity of the storage device. The fourth storage capacity is obtained by subtracting the second storage capacity from the third storage capacity. The fourth storage capacity represents a remaining storage capacity of the storage device.
Step 26: and calculating by using the fourth storage capacity and the writing speed to obtain the writing time of the data to be written.
The writing time to the storage means at the writing speed can be obtained by dividing the fourth storage capacity by the writing speed. This is an estimate.
Step 27: the first detection time is updated with the write time.
Specifically, referring to fig. 4, step 27 may be the following step:
step 271: a ratio between the writing time and the first detection time is calculated.
Step 272: and if the ratio is smaller than the preset value, calculating by using the first detection time to obtain second detection time.
If the preset value is 3, if the ratio is less than 3, dividing the first detection time by 2 to obtain a second detection time. And taking the second detection time as a time interval, and acquiring the storage capacity of the storage device after the second detection time is reached. It can be understood that when the ratio is smaller than the preset value, which means that the value of the fourth storage capacity is gradually decreased, the remaining storage capacity is decreased, and at this time, the detection time needs to be shortened, so that the storage capacity can be acquired in more detail.
And if the ratio is larger than or equal to the preset value, the current first detection time is still used as the time interval, and the storage capacity of the storage device is acquired after the first detection time is reached.
In an application scenario, a capacity class is set for a storage device in advance and a first weight is set for data to be written according to a type. Such as a log file, a multimedia file, etc., the first weight corresponding to the log file is 0.9, and the first weight corresponding to the multimedia file is 0.8. And acquiring the residual storable capacity of the storage device after the first detection time is reached. A capacity level may be determined based on the remaining storable capacity. Simultaneously acquiring a service scene corresponding to data to be written; acquiring a second weight corresponding to a service scene; for example, when the service scenario is in a service peak period, the corresponding second weight is 0.5, and when the service scenario is in a service off-peak period, the corresponding second weight is 1. And obtaining first detection time by using the first weight, the second weight and the standard detection time. Specifically, the first detection time is obtained by dividing the initial detection time by a value corresponding to the capacity class by using the first weight and the standard detection time, which is the initial detection time, and then multiplying the value by the second weight.
And the initial traffic peak value is the average value of the capacity detection results of the previous three times and is used as the writing speed, and the writing speed is updated from the fourth time of capacity detection if the latest peak value is larger than the previous value.
In the embodiment of the application, the corresponding detection time is determined by using different storage capacities, and corresponding weights are set according to the file type of data to be written, the service scene (service peak period and non-peak period) and the peak value change of the increase of the storage capacity in unit time; and calculating to obtain a storage capacity detection time by comprehensively considering the factors. On the premise of satisfying the disk capacity detection function, the detection time obtained according to the method can reduce the read-write operation on the disk, reduce the damage to the disk caused by long-term frequent read-write, prolong the service life of the disk, and reduce the resource loss of a Central Processing Unit (cpu) on the read-write of the disk
In other words, the embodiment of the present application does not simply determine whether to do nothing below the first threshold, and operates to reduce the writing speed above the second threshold; the first detection time is estimated according to the type of the current file written into the disk and the condition of the service scene, and the first detection time can be dynamically changed according to the positions of the current disk capacity at the first threshold and the second threshold; in addition, implementing i with our own device functionality increases that if the current disk capacity is greater than a second threshold, i will initiate an aging mechanism (i.e., delete the oldest written file).
According to the embodiment of the application, the data files with certain capacity can be dynamically reserved in the storage device of the equipment end after the equipment is disconnected with the external data acquisition equipment.
