Background
In recent years, with rapid development of industries such as cloud computing, big data, internet of things and the like, the demand for data storage is increasing. Because the nvmessd (non-volatile memory host controller interface specification solid state disk) has the characteristics of large capacity, high read-write speed, low io delay and the like, the market scale of the nvmessd is greatly improved no matter in a consumer-grade market or an enterprise-grade market, the nvmessd is already applied in a large scale in different application scenes, the use requirement on the nvmessd is more and more diversified, and the requirement on the reliability of the nvmessd is more and more high. When the server is in use and the nvmessd storage space is insufficient or fails, new nvmessd equipment needs to be added, decreased or replaced, and the nvmessd can be updated or expanded under the condition that the server is started up by the hot plug function of the nvmessd without influencing the normal operation of the system. Therefore, an nvmessd hot plug test method with higher test efficiency is needed.

one mode is realized by depending on an ipmitool tool through BMC (baseboard management controller) out-of-band management, the mode is large in limitation, and the mode can be realized only by supporting a BMC out-of-band management hot plug function by the test server and the test nvmessd at the same time, but most of the conventional mainstream servers do not support the BMC hot plug function. Moreover, the hot plug in this way cannot achieve the accurate control of the plugging time and speed, and also cannot achieve the non-notification hot plug test.
The other mode is realized by setting the POWER state corresponding to the PCIe card slot, which can be understood as unloading and loading nvmessd, the mode cannot fully simulate the test scene of the actual hot plug of the nvmessd, and only can support notification type hot plug and non-notification type hot plug.

and if the NVMe SSD to be tested is normally inserted, repeatedly executing the operation of controlling the hot plug equipment of the storage system component to carry out on-off control on the target signal pin according to the on-off delay information until the preset test times are reached.
8. A NVMe SSD hot plug testing device, the device comprising:
the device comprises an acquisition module, a test host and a storage system component, wherein the acquisition module is used for acquiring the device information of the NVMe SSD to be tested, and the NVMe SSD to be tested is connected to the test host through a hot plug device of the storage system component;
the configuration module is used for sending a configuration instruction to the storage system component hot plug equipment, wherein the configuration instruction carries preset test parameters and equipment information so that the storage system component hot plug equipment configures on-off delay information of a target signal pin according to the test parameters, the target signal pin is a signal pin for establishing a connection relation between an NVMe SSD to be tested and a test host corresponding to the equipment information, and the target signal pin comprises a power supply signal pin and a data signal pin;
the control module is used for controlling the hot plug equipment of the storage system component to carry out on-off control on the target signal pin according to the on-off delay information, so as to simulate the hot plug scene of the NVMe SSD to be tested by changing the on-off state of the target signal pin, and after the NVMe SSD to be tested is simulated to carry out hot plug, whether the NVMe SSD to be tested has abnormal data is judged according to the situation of writing data; the test host computer starts a double thread through the upper control software program, and the thread 1 is used for performing continuous data read-write operation on the NVMe SSD to be tested by using a storage device data read-write tool; and the thread 2 is used for controlling the hot plug equipment of the storage system component to carry out on-off control on the target signal pin according to the on-off delay information.
9. An NVMe SSD hot plug test device, comprising a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing the steps of the method as claimed in any of claims 1-7 when executing the computer program.
10. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 7.
