In this embodiment, a method for detecting performance of a hard disk is provided, and fig. 2 is a flowchart of a method for detecting performance of a hard disk according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:
step S202, a first instruction is obtained, wherein the first instruction is used for requesting a target hard disk to execute target processing;
in this embodiment, the first instruction includes an instruction instructing the target hard disk to perform a read operation, a write operation, or other operations, where the read operation is to read data or information stored in the target hard disk, and the write operation is to store external data or information in a target area of the target hard disk, where, to facilitate target storage, the first instruction further includes an identifier indicating the target process, such as a read identifier or a write identifier, etc., that identifies the target process indicated by the first instruction.
The manner of acquiring the first instruction may be, but is not limited to, storing in advance identification information corresponding to the first instruction, then, in the case of reading the first instruction, comparing an identification indicating target processing included in the first instruction with the prestored identification information, and taking a prestored instruction with the identification information being identical as the first instruction; or intercepting the first instruction, recording the identification indicating the target processing included in the first instruction, and forwarding the identification to the target hard disk; and continuously acquiring the information flow in the kernel mode in the forwarding process of the first instruction, and continuously analyzing the acquired information flow to acquire the first instruction contained in the information flow.
Taking an automatic hard disk performance test under linux as an example, a read-write IO instruction in a user mode is sent from the user mode to a kernel mode, then enters a hard disk performance detection module with a hard disk performance detection function through a file system layer, a BLOCK layer, a SCSI layer and a SCSI controller driving layer in the kernel mode, then the read-write IO instruction is sent to a target hard disk by the hard disk performance detection module, then the target hard disk acquires the read-write IO instruction, and executes the read-write IO instruction.
Step S204, obtaining first information of a first instruction, wherein the first information comprises first sending time for sending the first instruction, hard disk information of a target hard disk and processing capacity corresponding to target processing;
in the present embodiment, the first information further includes position information and the like of a target process corresponding to the first instruction in the target hard disk, for example, a target hard disk area in which a read operation is performed, a target hard disk area in which a write operation is performed, and the like; the first sending time may be (but is not limited to) a system time when the first instruction is sent for the user mode, or may be a system time when the hard disk performance detection module sends the first instruction; the hard disk information of the target hard disk includes (but is not limited to) model, identity ID, storage space, identification information and position information of the storage area, etc. of the target hard disk; the processing amount corresponding to the target processing includes the byte length of the first instruction, the data length of the target processing, the data amount thereof, and the like.
The manner of acquiring the first information of the first instruction may be (but is not limited to) that the first instruction is acquired by analyzing the first instruction after the first instruction is acquired, or may be that the identifier corresponding to the first information is identified and the first information corresponding to the identifier is recorded, or may be that the first information is searched after the first instruction is acquired, and then the searched first information is stored and recorded, which is not described herein again.
Step S206, a first instruction is sent to a target hard disk based on the hard disk information;
in this embodiment, after the hard disk performance detection module obtains the hard disk information, the first instruction is sent to the target storage area according to the identification information of the storage area in the hard disk information and the information such as the storage space size of the storage area, so that the target hard disk performs a corresponding operation in the target storage area, so that the target hard disk can have enough space to perform a corresponding target process, where the mode of sending the first instruction to the target hard disk may be data transmission in a serial mode or data transmission in a parallel mode.
It should be noted that, when the target hard disk has a plurality of input/output ports, the target hard disk may receive the first instruction together by the plurality of ports, the first instruction may be received in one-to-one manner by one port, or may be received in other manners, which will not be described herein.
Step S208, a first instruction response returned by the target hard disk after the target hard disk executes the target processing based on the first instruction is obtained;
in this embodiment, after receiving the first instruction, the target hard disk executes target processing such as a read operation or a write operation in the target storage area, and feeds back a first instruction response to the kernel state after completing the target processing, where the first instruction response includes (but is not limited to) information such as hard disk information of the target hard disk that completes the target processing, link negotiation rate of the target hard disk that completes the target processing, system time of the target hard disk that completes the target processing, and data length of the completed target processing, where the link negotiation rate refers to a rate at which data interaction is performed by a link connected between the target hard disk and the hard disk performance detection module.
The method for returning the first instruction response by the target hard disk may (but is not limited to) return by parallel transmission, may return by serial transmission, or may return by other methods.
For example, after the target hard disk finishes the target processing, a first instruction response is returned to the hard disk performance detection module in the kernel state, the hard disk performance detection module sends the first instruction response to the SCSI controller driving layer after obtaining the first instruction response, and the first instruction response returns to the user state through the SCSI layer, the BLOCK layer and the file system layer in sequence.
Step S210, obtaining second information of the first instruction response, wherein the second information comprises second sending time of the target hard disk for sending the first instruction response;
in this embodiment, after receiving the first instruction response returned by the target hard disk, the hard disk performance detection module analyzes the first instruction response to obtain second information included in the first instruction response, where the second information includes, in addition to the second sending time of the target hard disk to send the first instruction response, information such as a data length of the completed target processing.
Step S212, determining the performance of the target hard disk based on the time difference between the first transmission time and the second transmission time and the throughput.
In this embodiment, after the hard disk performance detection module obtains the second sending time, determining the time consumed by the target hard disk to execute the target processing by calculating the time difference between the first sending time and the second sending time, converting the rate of the target hard disk when executing the target processing according to the processing amount and the time consumed by the target hard disk to execute the target processing, and then determining the performance of the target hard disk according to the rate of the target hard disk when executing the target processing; the processing amount includes, but is not limited to, the data amount of the target processing, the data length of the first instruction, and the like.
Through the steps, the hard disk performance detection module directly detects the hard disk performance according to the information fed back by the hard disk, so that data deviation caused by the business of other layers is avoided, the problem of inaccurate hard disk performance detection is solved, and the hard disk performance detection precision is improved.

In this embodiment, the operation of executing the first instruction may be triggered by the kernel state actively by counting the total processing amount, or may be triggered by acquiring the hard disk performance detection instruction from another device, or may be triggered by other means.
The total processing amount corresponding to the target hard disk execution history processing includes (but is not limited to) the read data length, the write data length, the time consumed by the read IO instruction, the time consumed by the write IO instruction and the like of the target hard disk execution history processing. When the accumulated read data length and write data length reach a preset threshold, for example, the preset threshold is 1GB, the operation of acquiring the first instruction is triggered and executed.
The statistical process may be to record and store data length information and the like included in the first information and the second information when the first information of the first instruction and the second information of the first instruction response are acquired, and accumulate successively.
The process of triggering and executing the first instruction may be that a trigger instruction is sent to a port receiving the first instruction to enable the port receiving the first instruction to be in a receiving state, or that a receiving instruction is sent to the port receiving the first instruction to enable the corresponding port to start receiving the first instruction; it should be noted that, the operation of triggering execution of the first instruction is independent of whether the first instruction reaches the corresponding port, and only the corresponding port is in a state of receiving the first instruction.
