Method, device, device and storage medium for realizing nvme device debugging function

Abstract

The application discloses a method, a device, a device and a storage medium for realizing an NVMe device debugging function. Wherein, the method includes pre-creating the shared memory; generating an NVMe standard command based on prompting the user to input parameter information required by the NVMe command, and reading the NVMe standard command from the shared memory and sending it after detecting that the client sends a standard NVMe request to NVMe devices. Write the command execution result returned by the NVMe device into the shared memory, and feedback the debugging result by reading the command execution result from the shared memory. In the process of implementing the NVMe device debugging function in the unified storage system in this application, the user does not have high requirements for understanding the NVMe protocol, and the change of the NVMe debugging function basically does not affect the core code.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, electronic device, and readable storage medium for realizing an NVMe device debugging function in a unified storage system. Background technique [0002] A unified storage system is a storage system that can run and manage files and applications on a single device. Its essence is a networked storage architecture that can support file-based network-attached storage and data-block-based storage area networks. NVMe (Non Volatile Memory Host Controller Interface Specification, Non-Volatile Memory Host Controller Interface Specification) devices are also called NVMe disks and SSDs (Solid State Disk, solid state disks) are the evolution direction of storage disks. The storage system will provide full-featured, easy-to-use debugging of NVMe devices connected to the system, which is of great significance to developers, project implementers and service su...

AI Technical Summary

Problems solved by technology

In addition, the NVMe protocol itself is relatively complex, which also leads to frequent changes in the functions of the debugging interface. Based on efficiency considerations, the unified storage system is usually implemented by ultra-large-scale C or C++ codes. Due to changes in the requirements of the NVMe debugging function, changes in the storage core code is unacceptable

Based on this, the existing method in which users manually organize tens of bytes of binary instructions in NVMe commands to realize the debugging function of NVMe devices requires users to have a very high understanding of the protocol.
