Problems solved by technology

[0003] However, at present, SSDs on the market do not clearly indicate the impact index of OP capacity on SSD performance, and there is no good method for testing the optimal OP capacity of SSD in the prior art. The requirements for optimal performance require manual repeated testing, which is unfriendly and unrealistic to users, and cannot meet the requirements of product development speed and user application requirements.

specific Embodiment approach 1

[0030] figure 1 It is a specific embodiment of the method for testing the optimal OP capacity of SSD according to the present invention. In this embodiment, the method for testing the optimal OP capacity of SSD includes the following steps s1-s6, which improves the test speed and accuracy to a certain extent.

[0031] Step s1. Build a test prototype. N SSDs to be tested and at least one non-SSD storage device are installed in the built test prototype. A Linux operating system is installed in any non-SSD storage device, and the N SSDs to be tested are installed. The SSD models are the same, and N is greater than or equal to 2, and N≥2.

[0032] It should be noted that the N may be any integer greater than or equal to 2.

[0033] In addition, in order to increase the test rate and test accuracy, the number of SSDs to be tested installed in the built test prototype can be appropriately increased if the existing technology allows. For example, although the number of interfaces ...

specific Embodiment approach 2

[0043] figure 2 It is another embodiment of the method for testing the optimal OP capacity of SSD according to the present invention. In Embodiment 2, the method for testing the optimal OP capacity of SSD also includes steps s1-s6, specifically as follows:

[0044] Step s1. Build a test prototype. N SSDs to be tested and at least one non-SSD storage device are installed in the built test prototype. A Linux operating system is installed in any non-SSD storage device, and the N SSDs to be tested are installed. The SSD models are the same, and N≥2.

[0045] It should be noted that the N mentioned above can be any integer greater than or equal to 2, and there are 20 SSDs to be tested with the same model installed in the test prototype built in this embodiment.

[0046] In addition, in order to increase the test rate and test accuracy, the number of SSDs to be tested installed in the built test prototype can be appropriately increased if the existing technology allows. For exampl...

Abstract

The invention provides a method for testing the optimal OP capacity of an SSD, comprising the steps of: building a test prototype; Starting the testing prototype to enter the Linux operating system, obtaining the SN number and the disk position sequence of each SSD to be tested respectively, and recording the SN number and the disk position sequence to the device table according to the increasingsequence of the disk position sequence; according to the preset test strategy, resetting the OP capacity of each record in the equipment list corresponding to the SSD to be tested respectively; performing performance test on all SSDs to be tested; collecting the performance test results of each SSD to be tested, comparing the collected performance test results, and obtaining the optimal performance test results of the current model of SSD according to the comparison results; Then, according to the obtained optimal performance test results of the SSD of the current model, obtaining the optimalperformance of the SSD of the current model and the optimal OP capacity corresponding to the optimal performance correspondingly. The invention is used for improving the test speed and the accuracy ofthe test.

Description

technical field [0001] The invention relates to the field of servers, in particular to a method for testing the optimal OP capacity of an SSD, which is used for quickly testing the optimal OP capacity corresponding to the optimal performance of the SSD. Background technique [0002] The OP (Over-Provisioning, reserved space) on the SSD (Solid State Drives) refers to the capacity that the user cannot operate, and the size is the actual capacity minus the available capacity of the user. The OP area is generally used for optimization operations, such as garbage collection and bad block mapping. [0003] However, at present, SSDs on the market do not clearly indicate the impact index of OP capacity on SSD performance, and there is no good method for testing the optimal OP capacity of SSD in the prior art. Its optimal performance needs to be tested repeatedly manually, which is unfriendly and unrealistic to users, and cannot meet the requirements of product development speed and...
