Brief description of the drawings
Fig. 1 is the method flow schematic diagram of the embodiment of the present invention；
Fig. 2 is the test result schematic diagram of the embodiment of the present invention.
Embodiment
In order to the technical characterstic of clear explanation this programme, below by embodiment, and its accompanying drawing is combined, to this
Invention is described in detail.Following disclosure provides many different embodiments or example is used for realizing the different knots of the present invention
Structure.In order to simplify disclosure of the invention, hereinafter the part and setting of specific examples are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relation between various embodiments are discussed and/or set.It should be noted that part illustrated in the accompanying drawings is not necessarily to scale
Draw.Present invention omits the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting the present invention.
The present invention suitable multiple systems, it is described in detail herein with linux system.
First do preposition work：Main flow linux system is installed, and obtains root authority.Fio instruments are installed, then will be automatic
Change script file to copy under the assigned catalogue under system.
As shown in figure 1, a kind of method of automatic test SSD delays, specifically includes following steps：
Format SSD；To the SSD carry out order pretreatments after formatting；Perform SSD order delay test；Perform with
Machine pre-processes；Perform SSD random delay test；Output test result.
Formatting SSD specific method includes：Using format orders, junk data inside SSD is removed.
Because test delay need test SSD order read-write and random read-write delay, test this two parts it
Before the action that will first be pre-processed because SSD characteristics are under blank panel state, performance read-write is excessively outstanding, and data are forbidden
Really, so before test, it is necessary to there is preprocessing process.
The specific method of order pretreatment includes：Hard-disk content is purged using fio instruments, disk is subjected to 4K sequential writes
It is full 2 times；Blocksize size is 128K, queue depth 64, numjobs 1.
The specific method of order delay test includes：Execution sequence 4K read operations, Auto-matching drive；Execution sequence writes survey
Examination, automatically generates order delay test result.
The method of Auto-matching drive includes：Drive is checked using fdisk-l orders, according to defined drive with checking
It is right that the drive that arrives is carried out, if to success, carries out testing the disk.
In order delay test：During read operation, numjobs 1, queue depth 1, testing time 600s, per 5s
Take a point；During write operation, blocksize 4K, numjobs 1, testing time 600s, a point is taken per 5s.
The specific method pre-processed at random includes：Disk is carried out completely 2 times by overall random write using fio instruments；blocksize
For 4K, numjobs 2, queue depth 64.
The specific method of random delay test includes：Carry out the random read operations of 4K, Auto-matching drive；Random write is performed to survey
Examination, automatically generates random delay test result.
The method and the method one of Auto-matching drive in order delay test of Auto-matching drive in random delay test
Cause, just repeat no more herein.
In random delay test：In read operation, numjobs 1, queue depth 1, testing time 600s, per 5s
Take a point；In write operation, blocksize 4K, numjobs 1, queue depth 1, testing time 600s, taken per 5s
One point.
After the completion of carrying out automatic test, output test result.
As shown in Fig. 2 testing Memblaze SSD, two capacity points 1.6T and 3.2T in a series are tested,
Fig. 2 intuitively reflects test result.
Transverse axis represents capacity, and the longitudinal axis represents the time of delay, and unit is microsecond.Cylindricality 1 represents the data institute that 4K orders are read
Time, cylindricality 2 represent the time used in the data of 4K sequential writes, and cylindricality 3 represents the data of 4K random writes, and cylindricality 4 represents
The data of 4K random writes.
Simply the preferred embodiment of the present invention described above, for those skilled in the art,
Without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also regarded as this hair
Bright protection domain.
