Problems solved by technology

[0003] Under normal circumstances, before and after the power failure of the SSD, the data may be inconsistent before and after the power failure due to insufficient reconstruction or failure of the mapping table. If there is such a problem, the data will be lost seriously, and the experience of using such an SSD is relatively poor. , so it is necessary to detect the data consistency of the SSD before and after power failure when the SSD leaves the factory
[0004] Existing methods for testing the data consistency of SSDs before and after power failure are generally implemented by staff manually issuing commands, which is very time-consuming and laborious.
If the number of SSDs is relatively large, it often requires the cooperation of more people, the workload is heavy, time-consuming and laborious, the labor cost is high, and the test efficiency is low.

Abstract

The invention relates to a method and device for automatically testing influence of SSD power failure on data consistency. The method comprises the steps: building an automatic test environment; running the automatic test script in an automatic test environment; writing the test data into the SSD; restarting the SSD after power failure; and detecting the consistency of the test data before and after SSD power failure. The scheme of the method automatically tests the influence of SSD power failure on data consistency on the basis of the Driver Master, specifically including: automatically writing the test data before the SSD is powered off, reading the restarted test data after controlling the SSD to be powered off and restarted, and then judging the consistency of the data while human intervention is not needed, so that the test efficiency of the SSD data consistency is improved, and the test cost is reduced.

Description

technical field [0001] The invention relates to the field of SSD testing, and more specifically refers to a method and device for automatically testing the influence of SSD power failure on data consistency. Background technique [0002] Solid State Drives (SSD for short) are a kind of data storage medium. Solid State Drives usually include a controller chip (controller), flash memory (Flash), cache memory (RAM) and other related devices. Among them, the flash memory chip is a non-volatile storage medium, and will not lose data after the power supply is stopped, and the cache chip now usually uses DRAM (Dynamic Random Access Memory, dynamic random access memory). Data will be lost. In order to ensure the reliability of data storage, a backup power module is usually added to an enterprise-level SSD. After an external abnormal power failure, the SSD uses the internal backup power module to maintain power supply for a period of time, and transfers the data in the cache to the ...
