Description
Technical Field

The server plays a significant role in the wide application of cloud computing and big data, the storage is the server and an important part thereof, and the OCSSD is more and more widely applied to the server along with the continuous innovation of the storage technology. The ocsd is also called an open channel solid state drive, which is a special solid state disk, and the solid state disk does not implement a Flash Translation Layer (FTL) in the firmware of the drive, but transfers the management task of the physical solid state storage to the operating system, so that a special driver needs to be installed in the operating system in general ocsd usage, and the driver loads the ocsd during the server boot process, which lasts for a long time and is very easy to have an abnormal condition, and the reliability of the ocsd and its driver is related to whether the data is secure and reliable, and is very important for the server using the ocsd and its driver.
At present, the OCSD reliability test is mainly carried out by carrying out repeated restart tests on an OCSD server complete machine, including soft restart, hard restart and power-off restart, and whether abnormal error reporting occurs in the OCSD server complete machine restart test process or not is checked after the OCSD server complete machine restart test enters a system, so that the reliability of the OCSD is judged. The conventional testing method is to check the running state of the OCSSDs after all the OCSSDs are loaded by the driver, but the abnormal conditions occurring in the process of loading the OCSSDs by the driver cannot be fully verified.
Therefore, it is very necessary to provide a method and an apparatus for testing reliability of an open channel ssd and its driver, aiming at the above-mentioned drawbacks in the prior art.
