Description

Technical Field

[0002] SMART (Self-Monitoring Analysis and Reporting Technology, hereinafter referred to as SMART) records the health information of the solid-state drive, which is retained after the system power is turned on and off and can span the entire service life cycle of the solid-state drive; in the process of using the solid-state drive and analyzing its life or failure, SMART health information will provide very useful numbers. For example, the critical alarm (SMART Log byte position 00) will indicate whether there is an abnormal event such as the temperature is too high and exceeds the threshold or the available backup space is lower than the threshold; another example is the current operating temperature of the solid-state drive and the remaining life percentage recorded in the SMART log. Obviously, the information in the SMART log is very important, and its reliability directly affects the quality of the product and customer experience, so it is necessary to test and verify the information therein.

However, the amount of data written by the host to the hard disk and the number of write commands in the SMART log have not been tested and verified. When the host write amount recorded in the SMART log does not meet expectations and is much smaller than the actual host write amount, it will damage the interests of the solid-state hard disk supplier, and when the host write amount recorded in the SMART log is much larger than the actual host write amount, it will damage the interests of the customer.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] At present, the testing and verification in the prior art mainly checks whether the operating temperature of the solid-state hard disk in the SMART log will exceed the temperature in a continuous reading and writing environment, whether the available remaining space is reasonably reduced after long-term use, whether the number of power on and off times increases accordingly with the number of power on and off times of the system, and whether the number of abnormal shutdowns increases accordingly with the abnormal removal of the AC power supply. However, the amount of data written by the host to the hard disk and the number of write commands in the SMART log have not been tested and verified. When the host write amount recorded in the SMART log does not meet expectations and is much smaller than the actual host write amount, it will damage the interests of the solid-state hard disk supplier, and when the host write amount recorded in the SMART log is much larger than the actual host write amount, it will damage the interests of the customer. Therefore, the solid-state hard disk must be tested and verified in the SMART log when it leaves the factory. The amount of data written by the host to the solid-state hard disk.

[0054] Based on the above shortcomings of SMART log test, the present invention proposes a test verification method for the statistics of SMART data writing amount of solid-state hard disk.

[0060] In this embodiment, a test verification method for the statistics of the SMART data written amount of a solid-state drive is provided. The method uses the Driver Master software of ULINK and the matching PSPA (PCIe solid-state drive Power Adaptor, PCIe solid-state drive power adapter, hereinafter referred to as PSPA) hardware to write a script, thereby realizing the test verification of the host's write amount to the solid-state drive in the SMART log. The specific steps of the script execution include:

[0061] First, power on and read the SMART log information in the SSD, and record the current host write amount and the current host write command number in the SMART log information. Specifically, read the 512 bytes of SMART health information in the SSD Log page 02. Record the current host write amount in the SMART log information, byte positions 48-63. Record the current host write command number in the SMART log information, byte positions 80-95.

[0062] Next, a certain number of write commands are sent to write into LBA0; for example, 1050 write commands are sent to write into LBA0 (Logical Block Address, hereinafter referred to as LBA), and the LBA size is 512 bytes.

[0063] Then, record the latest data written amount in the SMART log information and the latest host write command number in the SMART log information. Calculate the difference between the latest data written amount in the SMART log information and the last recorded written amount, and determine whether the numerical increments at the corresponding positions of the SMART log bytes match. Calculate the difference between the latest host write command number in the SMART log information and the last recorded write command number, and determine whether the numerical increments at the corresponding positions of the SMART log bytes match. If they match, the test passes.

[0071] Calculate the difference between the latest host write command number in the SMART log information and the last recorded write command number, and determine whether the value at the position corresponding to the SMART log byte increases by 1051. If the count increases by 1051, it is a match, otherwise it is a mismatch;

[0074] Calculate the difference between the latest host data write amount to the SSD in the SMART log information and the last recorded write amount, and determine whether the value of the corresponding position of the SMART log byte increases by 3. If the count increases by 3, it is a match, otherwise it is a mismatch;

[0075] Calculate the difference between the latest host write command number in the SMART log information and the last recorded write command number, and determine whether the value at the position corresponding to the SMART log byte increases by 1051. If the count increases by 1051, it is a match, otherwise it is a mismatch;
