Particularly in the aspect of random writing, the performance of the SSD in the empty state at the beginning of random writing is good, but as the hard disk data is more and more, the garbage collection pressure of the hard disk is more and more increased, and wear leveling, cold and hot data redistribution and the like are performed under a certain condition, so that the performance of the hard disk is correspondingly reduced, and when the write performance of the hard disk and the garbage collection capability reach a balance, the steady state is entered.
When the SSD hard disk is in a stable state, the random writing performance can be basically kept unchanged, the server storage system tends to be stable at the moment, and on the premise, the related storage performance data of the server storage system is obtained to perform comprehensive functionality and stability tests on the server, so that the reliability of the result of the server test verification can be ensured.

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 invention.
The following explains key terms appearing in the present invention:
the SSD is a technology which abandons the traditional magnetic medium and adopts an electronic storage medium to store and read data, breaks through the performance bottleneck of the traditional mechanical hard disk and has extremely high storage performance.
IOPS (Input/Output Per Second), i.e., the Input/Output (or read/write times) Per Second, is one of the main indicators for measuring the performance of a magnetic disk. The IOPS refers to the number of I/O requests that the system can process per unit time, generally in units of the number of I/O requests processed per second, which are typically read or write data operation requests.
In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and the detailed description.
Fig. 1 is a flowchart illustrating a method for performing steady-state verification of SSD performance according to an exemplary embodiment, where as shown in fig. 1, the method for performing steady-state verification of SSD performance specifically includes the following steps:
SS1, obtaining a plurality of continuous IOPS effective average values;
SS2, obtaining a steady state value of the test performance according to the plurality of continuous IOPS effective average values;
and SS3, verifying SSD performance steady state according to the test performance steady state value.
For the technical scheme shown in fig. 1, it needs to be specially explained that the present invention realizes the verification of the SSD performance steady state through the above steps, and fills the blank in the current SSD performance steady state test. In addition, it is to be understood that, due to the inherent property of the SSD hard disk, that is, as the data of the SSD hard disk increases, the garbage collection pressure of the hard disk increases, and the hard disk may be subjected to wear leveling and cold and hot data redistribution, thereby causing the performance of the hard disk to decrease, and when the SSD hard disk enters a steady state balance, the storage system of the server may tend to be stable, and the stability of the storage system is crucial to the subsequent test and operation of the server, and the time for entering the SSD performance into the steady state is unclear, thereby causing the subsequent test of the server to be unstable. In addition, the performance steady-state value obtained in the step SS3 can reflect the read-write performance of the SSD to a certain extent.
As shown in the technical solution of fig. 1, it should be specially noted that a value of each of the steps SS1 and SS2 is usually 25.
The above-mentioned IOPS effective average value is a value defined in the present invention, and the explanation of the specific meaning depends on the obtaining step. As shown in fig. 2, obtaining the effective average specifically includes the following steps:
SS101, sampling IOPS to obtain a plurality of continuous IOPS values;
the SS102 acquires the average value of the plurality of continuous IOPS values and records the average value as the IOPS average value;
and SS103, verifying whether the IOPS average value is an IOPS effective average value.
In step SS103, the method for verifying whether the IOPS average is the IOPS valid average is as follows:
obtaining an effective interval according to the IOPS average value;
and if the plurality of continuous IOPS values are all in the effective interval, the IOPS average value is the IOPS effective average value.
The values of a plurality of the steps SS101 and SS102 are usually 5; the IOPS sampling in step SS101 is typically done once in 2 s.
The method for verifying the steady state performance of the SSD depends on the performance of the SSD, and the steady state performance verification of the SSD is realized through the performance of the IOPS in the embodiment; the IOPS refers to the number of I/O requests that the system can process per unit time, generally in units of the number of I/O requests processed per second, which are typically read or write data operation requests.
As shown in the technical solution of fig. 1, it should be specially described that the method for obtaining the steady-state value of the test performance according to the plurality of continuous IOPS effective average values in step SS2 specifically includes:

The above valid interval is obtained according to the steady state value of the test performance, which is usually 95% -105% of the steady state value of the test performance.
When the SSD enters a performance steady state, the performance steady state value can also be used as an evaluation index of the SSD hard disk performance.
For the technical solution in fig. 1, it is further to be understood that, before the technical solution in fig. 1 is executed to verify the stable performance of the SSD, the SSD hard disk needs to be preprocessed, and the processing method may be written twice in a full disk sequence.
For the technical solution of fig. 1, it should be noted that the SSD hard disk can be divided into a plurality of scenes according to the read/write ratio. For example, multiple scenes are obtained according to the read-write mixing ratio of 100/0, 95/5, 65/35,50/50,35/65 and 5/95. The technical solution shown in fig. 1 can be tested in any of the above scenarios, and it should be noted that the performance steady-state test values are different in the scenarios with different read-write mixing ratios.
With respect to the technical solution shown in fig. 1, it should be further specifically noted that, in step SS1, a plurality of consecutive IOPS effective average values need to be obtained, where the plurality of IOPS effective values need to be consecutive, and the continuity of the plurality of IOPS effective values depends on the continuity of IOPS sampling values.
Based on the same inventive concept of the foregoing embodiments, as shown in fig. 3, an embodiment of the present invention discloses a system for steady-state verification of SSD performance, which includes the following modules:

In addition, it is to be understood that, due to the inherent property of the SSD hard disk, that is, as the data of the SSD hard disk increases, the garbage collection pressure of the hard disk increases, and the hard disk may be subjected to wear leveling and cold and hot data redistribution, thereby causing the performance of the hard disk to decrease, and when the SSD hard disk enters a steady state balance, the storage system of the server may tend to be stable, and the stability of the storage system is crucial to the subsequent test and operation of the server, and the time for entering the SSD performance into the steady state is unclear, thereby causing the subsequent test of the server to be unstable. In addition, the performance steady state value in the SSD performance steady state verification module can reflect the read-write performance of the SSD to a certain extent.

When the SSD enters a performance steady state, the performance steady state value can also be used as an evaluation index of the SSD hard disk performance.
For the technical solution of fig. 3, it is further to be understood that, before verifying the performance steady state of the SSD in the technical solution of fig. 3, the SSD hard disk needs to be preprocessed, and the processing method may be to write the entire disk in sequence twice.
