Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the drawings and specific implementation methods. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0030] Traditional NVMe controllers do not support the NVMe networked storage protocol, which limits their applications. In response to this problem, this application provides an NVMe controller, a networked storage device and a networked storage system, which realizes the sending, receiving, processing and responding to commands of the networked NVMe storage protocol, has a clear modular structure, and is easy to integrate...

Abstract

The invention discloses an NVMe controller which is applied to networked storage equipment and comprises a packaging and unpacking module, a cache queue module, an instruction arbitration scheduling module, an instruction reading module, an instruction processing module, an interface module and an instruction response module. The scheme is realized based on hardware logic, supports transceiving, processing and response of commands of a networked NVMe storage protocol, and has the characteristics of clear modular structure and convenience in integration in a large-scale network system. In addition, the invention further provides a networked storage device and system, and the effect of the networked storage device corresponds to the effect of the NVMe controller.

Description

technical field [0001] The present application relates to the field of storage, in particular to an NVMe controller, a networked storage device and a networked storage system. Background technique [0002] NVMe is a protocol specially designed for flash storage devices. In the NVMe protocol, it is mainly divided into two parts: the host-side Host and the controller-side Controller. [0003] However, the current controller implementations are all SSD manufacturers' own design solutions, and the current controller design is still the traditional PCIe bus-based NVMe protocol, and lacks corresponding support for the newer NVMe networked storage protocol. Contents of the invention [0004] The purpose of this application is to provide an NVMe controller, a networked storage device and a networked storage system to solve the problem that the traditional NVMe controller does not support the NVMe networked storage protocol. The specific plan is as follows: [0005] In a first as...
