Abstract

The invention relates to the technical field of storage systems, and provides a networked storage system and method based on NVMe, wherein the system comprises a user layer, a terminal, a network storage terminal and an SSD flash; the terminal receives user commands and data from the user layer and converts the user commands and data into commands and data conforming to the NVMe-OF protocol and sends the commands and data confirming to the NVMe-OF protocol to the network storage terminal through a RDMA Fabric network link; the network storage terminal receives the commands and data confirmingto the NVMe-OF protocol sent by the terminal, analyzes the commands and the data, acquires the type of the commands and processes the data according to the type of the commands, the connection betweenthe terminal and the network storage terminal is achieved a hardware logic, the modularization structure is clear, the performance is high, and the system can be conveniently integrated into a systemenvironment of storage and acceleration and the like.

Description

technical field [0001] The invention belongs to the technical field of storage systems, and in particular relates to an NVMe-based networked storage system and method. Background technique [0002] The non-volatile memory host controller interface (Non-Volatile Memory express, NVMe) is a protocol specially designed for flash memory storage, which can make full use of the low latency and parallelism of the PCIe (peripheral component interconnect express) channel, greatly Improve the read and write performance of solid state drives. NVMe over Fabric (NVMe-OF) is a specification developed from the basic NVMe protocol to carry NVMe functions in the network transport layer. Traditional NVMe is based on the PCIe bus and can only complete the transmission between the host and local storage devices, while NVMe-OF can be constructed on the basis of other transport layer protocols. Through the network interconnection structure, the host can access any storage node. Provides a high-p...
