Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 shows a flowchart of a method for testing a solid state disk according to an embodiment of the present invention. As shown in fig. 1, the method for testing a solid state disk according to the embodiment of the present invention includes the following steps:
step S1: dividing the solid state disk into N parts according to the capacity, and recording the position information of each part of the capacity of the hard disk, wherein N is an integer greater than 1.
Specifically, the solid state disk is divided into N parts according to the capacity C, where N is an integer greater than 1, the division mode may be equal or unequal, each obtained part is the capacity of each hard disk, and then position information of the capacity of each hard disk obtained by the division is recorded, where the position information includes an offset parameter and a data size parameter. For example, when the capacity C of a solid state disk is equally divided into 10 copies and the position information of each copy of the capacity of the hard disk is set by the offset parameter and the size parameter, the data size of each copy of the capacity of the hard disk is size =10% C, and the offset amounts from the 1 st copy to the 10 th copy are offset =0% to offset =90% C in this order.
Step S2: and sequentially writing data with corresponding capacity into each capacity of the hard disk at different time points according to the position information of each capacity of the hard disk.
Specifically, after the capacity of the solid state disk is divided, each capacity of the hard disk has a corresponding size, and then according to the position information of each capacity of the hard disk, data with corresponding capacity is sequentially written into each capacity of the hard disk at different time points, so that cold and hot data with different writing time are constructed in the solid state disk. For example, if the capacity C of a solid state disk is equally divided into N, the capacity corresponding to each capacity of the disk is equal to
At time t1, write to the 1 st copy of the solid state disk capacity
The data of the size is written into the 2 nd copy of the solid state disk capacity at the time t2
Size data, and repeating until the Nth copy of the solid state disk is written
The data size is different, so that the writing time of each volume in the solid state disk is different, the data retention time is different, and cold and hot data are constructed in the solid state disk.
In an embodiment of the present invention, before sequentially writing data with corresponding capacities into the respective capacities of the hard disk at different time points according to the location information of the respective capacities of the hard disk in this step, the method further includes: and carrying out full-disk writing of data on the solid state disk.
Specifically, before writing data with corresponding capacity into each capacity of a hard disk in the solid state disk, the data of the solid state disk is written into the solid state disk in a full disk mode, and the solid state disk is written into the solid state disk in a full disk mode, so that the data in the solid state disk are guaranteed, and then the solid state disk can be tested after any one hard disk is written into the data with the corresponding capacity, and the testing time of the solid state disk is flexible.
In an embodiment of the present invention, sequentially writing data with corresponding capacities into each capacity of the hard disk at different time points in this step includes: and sequentially writing data with corresponding capacity into each capacity of the hard disk according to the writing time interval corresponding to each capacity of the hard disk.
Specifically, in the embodiment, different writing time intervals are set for each capacity of the hard disk in the solid state disk, so that data with corresponding capacity is written into each capacity of the hard disk sequentially at different time points, and then cold and hot data in the solid state disk is constructed. The writing time interval corresponding to each capacity of the hard disk can be randomly generated or determined according to a functional relationship, so that the process of storing data when a user actually uses the solid state disk is better simulated.
According to the solid state disk testing method provided by the embodiment of the invention, the capacity is divided into a plurality of parts from the capacity of the solid state disk, and each part is subjected to writing operation after different time intervals, so that the thought is simple and clear, the realization is easy, the retention time of cold data in the solid state disk is different, the effectiveness of the solid state disk testing method is ensured, and the testing flexibility is improved.
In an embodiment of the present invention, the write-in time interval corresponding to each capacity of the hard disk is determined by a preset time function, and the time function represents a relationship between the write-in time interval and the identification information of each capacity of the hard disk.
Specifically, the identification information of each hard disk capacity represents the sequence of writing data to each hard disk capacity, such as the number and serial number of each hard disk capacity, and has a corresponding relationship with the position information of each hard disk capacity. For example, the capacity C of the solid state disk is divided into N, and the identification information, which is the number corresponding to each capacity of the hard disk, is 12,3, …, N in sequence. The writing time interval corresponding to each capacity of the hard disk is t, a time function t = f (N), N =1,2 … N is set, the time function represents the relationship between the writing time interval t corresponding to each capacity of the hard disk and the identification information N of each capacity of the hard disk, and a specific function body can be set with different functions according to actual test requirements.
According to the test method of the solid state disk, provided by the embodiment of the invention, through setting different time interval functions, the structure is compact in the aspect of realizing logic, and the retention time of cold data in the solid state disk can be controlled, so that cold and hot data under different scenes can be simulated, and the firmware related functions of the solid state disk can be verified more comprehensively.
In one embodiment of the invention, the function of time comprises a non-linear function.
Specifically, the non-linear function, i.e., the function image, is not a function of a straight line, and includes an exponential function, a logarithmic function, a power function, a polynomial function, and the like. For example, the capacity C of the solid state disk is divided into 10 parts, and the numbers corresponding to the capacities of the hard disk parts, i.e., identification information, are 1,2,3, …, and 10 in sequence; setting a writing time interval t corresponding to each capacity of the hard disk as a power function, wherein t =
N =1,2 … 10, with the unit being h (hours). Therefore, a nonlinear function relation is constructed to show different writing time intervals corresponding to each capacity of the hard disk. By setting the nonlinear function as the time function, the input process of cold and hot data in a real scene can be better simulated, the firmware function of the solid state disk can be verified more comprehensively, and the flexibility and the comprehensiveness of the test are improved.

The test on the solid state disk can be based on any tool having a read-write function on the solid state disk, such as a fio tool.
In one embodiment of the present invention, the testing in this step comprises: electrical resting test or read test.
Specifically, the electric standing test is an electric standing test, which means that the solid state disk is electrified and is not operated; read tests include read-write tests, and the like.
