Abstract

The present application provides a fault simulation and emulation method and related equipment, wherein the method includes: receiving a processing command sent by a host device; searching for a first fault corresponding to the processing command in a preset fault information set according to the processing command information; if the first fault information is found, process a response to the host device according to the first fault information. The solution of the present application can truly simulate the failure scenarios of the storage device, cover various possible failure scenarios of the storage device, and improve the test reliability.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a fault simulation and emulation method and related equipment. Background technique [0002] Non-volatile memory (Non-Volatile Memory express, NVMe) is a new storage standard. Compared with other storage standards, it simplifies the calling method, has more queues, and can achieve a larger queue depth. Therefore, devices using the NVMe standard have lower latency, higher transmission performance, and lower power consumption control. NVM devices are the evolution direction of current storage devices. With the birth of NVMe devices, host devices need to be redesigned, developed, and debugged to create new host devices that match NVM devices in all aspects. How to quickly make It is undoubtedly a huge challenge for new host devices to stabilize. [0003] In the customer application process, when the storage device fails, the software of the host device needs to quickly and effecti...
