Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In an embodiment of the present invention, the RDT duration test mode and pass standard may be as follows: assuming known conditions for the test disk, 1.6T capacity, 3 DWPD, 5 warranty years PE 10K, 1000Hours test time, JEDEC218 test workload (BS 512/4:1024/1:1536/1:2048/1:4K/70:8K/10:16K/7:32K/3:64K/4, 40 rwmixread)
The test passed the standard, test 1000H using JEDEC218, PE (Program and Erase) of the disc reached 10K, and the statistical write data amount (TBW) satisfied or more: 1.6T 3 x 5 x 365T 8760T (calculated as 3 full disk writes per day for a total of 5 years). Wherein, the SSD life cycle write data volume is represented by TBW.
The test passes 2 indexes of the standard, 1, PE reaches 10K; 2, TBW satisfies the prescribed data amount. PE reaches the NAND capability of the 10K embodiment, i.e. the expected 10K PE lifetime. TBW refers to the write capability of the user data volume, i.e., to satisfy the user write volume requirement.
The link between the two metrics is an important parameter of SSD: WA, i.e., write amplification (NAND write amount/host write amount).
The following examples are given: the user capacity is 1.6T, OP (reserved space of SSD) is 30%, DWPD (write several times of full disk every day) is 3, quality guarantee is 5years, PE is 10K, WA is 2.5;
therefore, the user write amount TBW: 1.6T 3 x 5 x 365T 8760T,
the nand writing amount is TBW WA 8760 w 2.5 21900T
PE equals 21900/(1.6 × 1+0.3)) -10K.
It can be seen that if WA becomes large, the NAND write amount tends to increase, i.e., TBW is less than a prescribed value, PE has worn down to 10K, resulting in the disc being unusable earlier.
The invention simulates the normal capacity disc by using part of the storage space of the normal disc as the small capacity disc, so that the small capacity disc also needs to reach 2 indexes which pass the RDT test. I.e. the write amplification needs of the small capacity disc are kept almost identical to the normal capacity disc. Thus, when the write amplification of the small capacity disk OP is almost consistent with that of a normal disk, the performance is kept consistent, because the small capacity disk has small capacity, the PE of the small capacity disk wears out faster in the same time, less time is needed for reaching the expected PE of 10K, and the test efficiency is improved.
According to an aspect of the present invention, an embodiment of the present invention provides a hard disk stress testing method, as shown in fig. 1, which may include the steps of:
s1, acquiring a reduction proportion and a reserved space proportion;
s2, determining user capacity and NAND capacity according to the reduction ratio and the reserved space ratio to determine storage space based on the user capacity and the NAND capacity;
s3, calculating expected write bandwidth according to the test parameters, the user capacity and the NAND capacity;
s4, writing data into the storage space and detecting the actual write bandwidth;
s5, responding to the actual writing bandwidth is larger than the expected writing bandwidth, and calculating the writing time ratio by using the actual writing bandwidth and the expected writing bandwidth;
s6, responding to the write time ratio is larger than a threshold value, calculating an expected PE value by using the currently written data, the expected write amplification, the user capacity and the reserved space ratio;
and S7, detecting the actual PE value and comparing with the expected PE value to adjust the proportion of the reserved space until the error between the two is less than the threshold value, thereby determining the storage space for pressure test in the hard disk to be tested by using the reduced proportion and the adjusted reserved space.
The scheme provided by the invention can simulate the pressure test of the whole disk by only carrying out the pressure test on part of the storage space of the hard disk through the feedback adjustment method until the most suitable user capacity and NAND capacity are found, thereby shortening the test period and maintaining the high quality and stability of the test.
In some embodiments, further comprising:
in response to the actual write bandwidth being less than the desired write bandwidth, reducing the reduction ratio and returning to the step of determining user capacity and NAND capacity from the reduction ratio and reserve space ratio to determine storage space based on the user capacity and NAND capacity until the actual write bandwidth is greater than the desired write bandwidth.
In some embodiments, further comprising:
and responding to the writing time ratio being smaller than a threshold value, increasing the reduction ratio, and returning to the step of determining the user capacity and the NAND capacity according to the reduction ratio and the reserved space ratio to determine the storage space based on the user capacity and the NAND capacity until the writing time ratio is larger than the threshold value.
In some embodiments, detecting an actual PE value and comparing to an expected PE value to adjust the headspace ratio until the difference is less than a threshold, further comprises:
in response to the actual PE value being greater than the expected PE value, reducing the proportion of the reserved space according to a preset proportion;
and in response to the actual PE value being less than the expected PE value, increasing the proportion of the reserved space according to the preset proportion.
Specifically, because the OP of the small-capacity disk coincides with the normal disk capacity OP, the NAND capacity is: user capacity (1+ OP), i.e. user capacity is determined, NAND capacity is also determined, and the adjustment of NAND capacity mainly adjusts the number of BLOCKs of the disk (the number of BLOCKs can be adjusted by adjusting firmware), assuming that NAND capacity is NAND _ CAP, so the number of BLOCKs is: NAND _ CAP/channel _ NUM/CE _ NUM/LUN _ NUM.
Known test parameters: DWPD is 3, and test duration 1000H, PE need grind to 10K, reach the write bandwidth of normal disk capacity P.
In determining the user capacity, the disc capacity may be indicated by C, assuming a normal capacity of 3.84T, i.e. set to 3.84 x 0.3 and approximately 1000G, based on an initial reduction scale (e.g. 30%).
And then determining the write bandwidth requirement according to the TBW and the test duration.
P _ expect ═ C × DWPD ═ 5YEARS · 365(365days/Years)/1000h (test duration), i.e. the write bandwidth requirement is: 1000G 3 × 5 × 365 × 1000/(1000 × 3600) ═ 1520 MB/s.
Then, the write bandwidth is judged to be in accordance with the expectation. The write bandwidth of the current small-capacity disk can be measured, the actual write bandwidth is compared with the expected write bandwidth, if the actual write bandwidth is smaller than the expected write bandwidth, the disk capacity is required to be reduced, namely the user capacity is set to be 20% of the normal capacity, and the previous steps are repeated until the actual write bandwidth is larger than the expected write bandwidth. If the actual write bandwidth is larger than the expected write bandwidth, the disk capacity is not overlarge, and the debugging of the subsequent steps is continued.
Then, the capacity adjustment is performed while focusing on the read/write time ratio. Assuming that the actual write bandwidth is P _ real, the calculated write bandwidth requirement is P _ expect, so the idle time of the test process is:
1-(1/(P_real/P_expect))
that is, the smaller the actual capacity of the small-capacity disk, the easier the write bandwidth will meet the desired write bandwidth requirement, and the requirement for the amount of data written per hour will be reduced, but the idle waiting time will be too long (although the idle time can be occupied by reading), and it will be very easy to cause the temperature control imbalance and the test jitter. The write time ratio can be increased by increasing the user capacity, and the previous steps are repeated until the write time ratio is larger than the preset value. In some embodiments, the write time duty cycle of a small capacity disc is generally adjusted to be as high as 80% or more.
Finally, it is determined whether the PE increase is expected. PE is expected to increase the computational effort: the user write data amount WA/(user capacity (1+ OP)), that is, the NAND total write amount/NAND capacity.
If the actual measured PE increases faster than the expected PE, indicating that the actual WA is higher than expected, a proper amount of WA reduction is required, the reduction method is to increase the OP space, if the PE increases slower than the expected PE, indicating that the actual WA is smaller than expected, a proper amount of WA increase is required, the increase method is to decrease the OP space, and it is noted that the proportion of fine adjustment should be less than 10%, otherwise, indicating that the theoretically calculated NAND space is not accurate.
The scheme provided by the invention can simulate the pressure test of the whole disk by only carrying out the pressure test on part of the storage space of the hard disk through the feedback adjustment method until the most suitable user capacity and NAND capacity are found, thereby shortening the test period and maintaining the high quality and stability of the test.
