Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection of the present invention. scope.

As shown in Figure 1, an embodiment of the present invention provides a method for detecting a hard disk, which may include the following steps:

S1: determine the target hard disk;

S2: respectively detecting the first detection value of the performance parameter when the target hard disk is connected to each hard disk connection module of the server to be tested;

S3: According to the first detection value corresponding to each hard disk connection module, determine whether each hard disk connection module on the server to be tested meets the requirements, if yes, perform step S4, otherwise, adjust the hard disk connection that does not meet the requirements module, after the adjustment is completed, return to step S2;

S4: Connect each hard disk connection module to the corresponding hard disk to be tested;

S5: Detect each hard disk to be tested, and determine a second detection value of a performance parameter of each hard disk to be tested.

The hard disk is connected to the server by connecting with the hard disk connection module. If the hard disk connection module does not meet the requirements, it will affect the accuracy of the detection result of the hard disk. A method for detecting the hard disk provided by the embodiment of the present invention uses the target hard disk The performance of each hard disk connection module on the server to be tested is determined whether it meets the requirements, and the hard disk connection modules that do not meet the requirements are adjusted. After all the hard disk connection modules meet the requirements, all the hard disks to be tested on the server to be tested are adjusted. The detection eliminates the influence of the hard disk connection module on the detection result of the hard disk to be tested, and can make the detected performance of the hard disk more accurate.

In order to make the measurement result more accurate, one of the hard disks to be tested can be used as the target hard disk. In a possible implementation, the S1 includes:

Carrying out monomer detection for each hard disk to be tested deployed outside the server to be tested;

Obtain the third detection value of the performance parameter of each hard disk to be tested;

The hard disk to be tested corresponding to the third detection value closest to the average value of all the third detection values is used as the target hard disk.

The target hard disk is used to verify the hard disk connection module. The hard disk to be tested is more compatible with the hard disk connection module in the server to be tested. Using one of the hard disks to be tested as the target hard disk can make the verification result more accurate. The target hard disk should be able to represent the performance status of each hard disk to be tested, so the hard disk to be tested with average performance can be selected.

In a possible implementation manner, before the step S3, it also includes: using the third detection value closest to the average value of all third detection values as a reference value;

Before the S3, it also includes: determining a threshold according to the reference value;

The S3, including:

Judging whether each first detection value is greater than or equal to the threshold, if yes, then determining that each hard disk connection module meets the requirements, and performing step S4, otherwise, determining the hard disk connection module corresponding to the first detection value smaller than the threshold If it does not meet the requirements, adjust the hard disk connection module that does not meet the requirements. After the adjustment is completed, return to step S2.

In this implementation, the third detection value is obtained by detection outside the server to be tested, and is not affected by the hard disk connection module. A reference value is selected from these third detection values, and the threshold value obtained through the reference value is compared with the threshold value received by the hard disk. The first detection value measured under the influence of the connection module is compared to determine whether the hard disk connection module meets the requirements, so that the obtained result is more accurate. If the data measured under the influence of the hard disk connection module is used as the reference value, the first detected value and the reference value both include the factors affected by the hard disk connection module, and the hard disk connection module cannot be accurately judged. does it reach the requirement. In addition, in order to make the detection result more accurate, when the target hard disk is connected to the hard disk connection module, the hard disks corresponding to other hard disk connection modules are also running in the server, so that it can more accurately reflect the running status of the hard disk in the server. Also, when determining the threshold, 80% of the reference value may be used as the threshold.

In S5, in order to detect the performance of the hard disk to be tested more accurately, when the current hard disk to be tested is tested, the other hard disks to be tested are kept running normally, so as to more accurately reflect the operating environment of the hard disk in the server.

In a possible implementation manner, the S5 includes:

Adjust the rotation speed of the fan of the server to be tested, detect each hard disk to be tested at each wind speed, and determine the second detection value of the performance parameter of each hard disk to be tested at each wind speed.

The performance of the hard disk will be affected by the vibration of the hard disk, and in the server, most of the vibration comes from the fan of the server. Therefore, by measuring the performance of the hard disk to be tested under different wind speeds, the performance of the hard disk to be tested can be presented more accurately and comprehensively.

When adjusting the fan speed, the fan speed can be adjusted to 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% of the maximum speed, and each situation can be detected.

In a possible implementation, it includes: the performance parameters include: IOPS (Input/OutputOperationsPerSecond, the number of read and write operations per second) in 4k random read and write mode, and IOPS in 256k sequential read and write mode.

In a possible implementation manner, the hard disk connection module includes: a hard disk slot and a hard disk backplane.

In addition, when determining the target hard disk, when each hard disk to be tested is tested individually, in order to reduce the impact of the external environment, especially vibration, on the performance of the hard disk, the hard disk to be tested can be fixed on the fixture to reduce the impact of the external environment on the hard disk. vibration, and reduce the vibration of the hard disk itself.

When putting the target hard disk into the server to be tested and testing the hard disk to be tested on the server to be tested, in order to reduce the impact of external vibration on the server, the server can be placed on a marble platform, keeping the planes facing each other. Smooth and flat, this marble platform has a large mass to the outside world, eliminating the transmission of external vibrations to the server, so that the measurement results are mainly affected by the server itself and are more accurate.

When detecting the hard disk, it can be realized by IOMeter software. When testing the IOPS in the 4k random read and write mode and the IOPS in the 256k sequential read and write mode, each mode runs for more than 2 minutes, which can make the measurement results more accurate.

In a possible implementation, after S4, it also includes: setting the fan of the server to be tested to an automatic adjustment mode, detecting each hard disk to be tested, and determining the evaluation reference value of the performance parameter of each hard disk to be tested ; Determine the evaluation threshold corresponding to each hard disk to be tested according to the evaluation reference value corresponding to each hard disk to be tested.

After S5, the method further includes: performing performance evaluation on each hard disk to be tested according to whether the second detection value of each hard disk to be tested is greater than or equal to a corresponding evaluation threshold.

Through this implementation, after the second detection value of each hard disk to be tested is determined, each hard disk to be tested can be evaluated according to the second detection value. The evaluation threshold can also be realized in the following way: set the wind speed of the fan at the natural wind speed, that is, the fan is normally adjusted by the server according to the needs. The evaluation detection value of the hard disk to be tested is used as its evaluation reference value, that is to say, the evaluation reference value of each hard disk to be tested may be different from each other, which is related to the performance of the hard disk itself. Determine the evaluation threshold value according to the evaluation reference value, for example: for the hard disk of SATA (SerialATA, serial port hard disk) type, 80% of its evaluation reference value can be used as its evaluation threshold value; For a hard disk, 85% of its evaluation reference value can be used as its evaluation threshold. Then, compare the second detection value of each hard disk to be tested with its corresponding evaluation threshold, if it is greater than or equal to its evaluation threshold, it is determined that the performance of the hard disk to be tested is good, and if it is less than its evaluation threshold, then it is determined that the performance of the hard disk to be tested is Poor, need to improve its performance.

When improving the performance of the hard disk, the following methods can be adopted: improve the mechanical design of the front window of the hard disk to reduce the vibration transmission energy of the high-speed rotation of the fan; optimize the circuit design of the hard disk backplane to reduce impedance and signal transmission interference, and improve the hard disk performance. Read and write performance values.

In addition, in a possible implementation manner, it also includes: taking the third detection value of the performance parameter of each hard disk to be tested as the evaluation reference value corresponding to each hard disk to be tested, and according to the evaluation standard value corresponding to each hard disk to be tested value to determine the evaluation threshold corresponding to each hard disk to be tested.

After S5, the method further includes: performing performance evaluation on each hard disk to be tested according to whether the second detection value of each hard disk to be tested is greater than or equal to a corresponding evaluation threshold.

Through this implementation method, the performance of each hard disk to be tested outside the server is compared with the performance of each hard disk to be tested in the server, which can reflect the impact of the hard disk connection module on the performance of the hard disk to be tested, and then the hard disk connection module. Make optimization adjustments.

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

In the embodiment of the present invention, performance testing needs to be performed on 8 hard disks to be tested in server A, and the 8 hard disks to be tested are hard disk 1, hard disk 2, hard disk 3, hard disk 4, hard disk 5, hard disk 6, hard disk 7, hard drive8. The performance parameter to be obtained is IOPS in 4k random read/write mode.

As shown in Figure 2, the embodiment of the present invention provides a method for detecting a hard disk, the method may include the following steps:

Step 201: Perform individual detection in 4k random read-write mode on each hard disk to be tested deployed outside server A.

In order to avoid the impact of server A on the performance of each hard disk to be tested, the hard disk to be tested is deployed outside server A for detection, and hard disks 1 to 8 are independently tested.

Step 202: Obtain a third detection value of the IOPS of each hard disk to be tested.

For example, the detected IOPS values of the hard disks 1 to 8 are 6000, 4500, 4000, 3500, 3000, 2500, 2000, and 1000 in sequence.

Step 203: Taking the third detection value closest to the average value of all third detection values as a reference value, and taking the hard disk to be tested corresponding to the third detection value closest to the average value of all third detection values as the target For the hard disk, 80% of the reference value is used as the threshold, and the reference value is determined to be 3500, the target hard disk is hard disk 4, and the threshold is 2800.

For example, the average value of all the third detection values is 3312.5, and the third detection value closest to 3312.5 is the third detection value 3500 of the hard disk 4. Therefore, the reference value is 3500 and the target hard disk is the hard disk 4.

Step 204: Detect the hard disk 4 connected to each hard disk connection module of the server A respectively.

Each hard disk is connected to server A through a hard disk connection module. The hard disk connection modules connected from hard disk 1 to hard disk 8 are: hard disk connection module 1, hard disk connection module 2, hard disk connection module 3, hard disk connection module 4, and hard disk connection module. 5. A hard disk connection module 6 , a hard disk connection module 7 , and a hard disk connection module 8 . Connect the hard disk 4 to the hard disk connection module 1 to the hard disk connection module 8 respectively, connect it to the server A, and then perform detection, that is to say, connect the hard disk 4 to the hard disk connection module 1, and detect the hard disk 4; connect the hard disk 4 Connect with the hard disk connection module 2 to detect the hard disk 4; and so on.

In addition, when the hard disk 4 is connected to any hard disk connection module, other hard disk connection modules are also connected to corresponding hard disks, and each hard disk operates normally. Specifically, when the hard disk 4 is connected to the hard disk connection module 1, the hard disk connection module 2 is connected to the hard disk connection module 8 in sequence: hard disk 2, hard disk 3, hard disk 1, hard disk 5, hard disk 6, hard disk 7, hard disk 8, or hard disk The connection module 4 is not connected to a hard disk, and other hard disk connection modules are connected to corresponding hard disks.

Step 205: Obtain the first detection value of the IOPS of the hard disk 4 when connected to each hard disk connection module.

For example, the first detection values of IOPS when the hard disk 4 is respectively connected to the hard disk connection module 1 to the hard disk connection module 8 are: 4000, 3800, 3200, 3500, 3000, 2900, 2995, 2895.

Step 206: Judging whether each first detection value is greater than or equal to the threshold 2800, if the judging result is yes, it is determined that each hard disk connection module meets the requirements.

In addition, when the judgment result is negative, it is determined that the hard disk connection module corresponding to the first detection value smaller than the threshold does not meet the requirements, and the hard disk connection module that does not meet the requirements is adjusted. After the adjustment is completed, return to step 204 . Specifically, if the first detection value of the IOPS when the hard disk 4 is connected to the hard disk connection module 5 is 2500, then the hard disk connection module 5 does not meet the requirements, and the hard disk connection module 5 is adjusted. After the adjustment is completed, return to step 204 and start again. detection.

Step 207: Connect each hard disk connection module with the corresponding hard disk to be tested.

Specifically, the hard disks to be connected to the hard disk connection module 1 to the hard disk connection module 8 are: hard disk 1, hard disk 2, hard disk 3, hard disk 4, hard disk 5, hard disk 6, hard disk 7, and hard disk 8.

Step 208: Adjust the rotation speed of the fan of server A, detect each hard disk under test at each wind speed, and determine the second detection value of the performance parameter of each hard disk under test at each wind speed.

Specifically, adjust the wind speed of the fan to 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% of the maximum wind speed, and detect the second speed of each hard disk to be tested at each wind speed. detection value.
