To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and join
According to attached drawing, the embodiment of the present invention is further described.
It should be noted that all statements for using " first " and " second " are for distinguishing in the embodiment of the present invention
Two non-equal entities of same names or non-equal parameter, it is seen that " first " " second " only for statement convenience, no
It is interpreted as the restriction to the embodiment of the present invention, subsequent embodiment no longer illustrates this one by one.
Based on above-mentioned purpose, the first aspect of the embodiment of the present invention proposes a kind of test side of NVME solid state hard disk
The embodiment of method.Shown in fig. 1 is the process signal of the embodiment of the test method of NVME solid state hard disk provided by the invention
Figure.As shown in Figure 1, the embodiment of the present invention includes following steps:
S1, the corresponding processor core of NVME solid state hard disk is obtained；And
S2, processor core and test load are bound and run test.
NVME full name Non-Volatile Memory Express, nonvolatile memory standard are logical using PCI-E
A kind of specification of SSD just has the low delay and concurrency for making full use of PCI-E SSD at the beginning of the design of NVME,
There are also current generation processor, platform and the concurrencys of application.Each NVME solid state hard disk has corresponding processor core, and
And the number of the corresponding processor core of each NVME solid state hard disk is not fully identical, for example, some NVME solid state hard disks
Corresponding two processor cores, and corresponding three processor cores of some NVME solid state hard disks.By different processor core point
The performance of different processor cores can be tested by not carrying out binding from different test loads.By processor core and test
Load is bound, and indicates that the NVME solid state hard disk for being transmitted directly to input/output function to be under the jurisdiction of processor core carries out
Random read-write test.Processor core and test load are carried out binding can be using I/O performance testing tool, such as FIO.
