A storage system and a solid state disk switching device thereof

Abstract

The invention discloses a solid state disk switching device and a storage system, and the solid state disk switching device comprises a first connector which is used for being connected with one of anonvolatile memory host controller interface specification NVMe solid state disk and an external device in a port mode matching manner after configuration is completed; a second connector which is used for being connected with the NVMe solid state disk and the other port mode matched with the port mode in the external equipment after configuration is completed; a processing module which is respectively connected with the first connector and the second connector, wherein the configuration module is used for configuring the first connector and the second connector into different preset port modes when triggered by a preset condition, transmitting data transmitted by the first connector to the second connector, and transmitting the data transmitted by the second connector to the first connector, wherein the port mode comprises a single-port mode and a dual-port mode. According to the present invention, the port mode of the NVMe solid state disk can be converted.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a solid-state hard disk transfer device, and also to a storage system. Background technique [0002] In recent years, the development of solid-state drives has become more and more mature. Among them, there is a kind of NVMe (Non-Volatile Memoryexpress, non-volatile memory host controller interface specification) solid-state drives can be divided into single-port type and dual-port type, single-port type NVMe Solid-state drives can realize single-channel data transmission on one physical interface, while dual-port NVMe solid-state drives can realize two-channel data transmission on one physical interface, single-port NVMe solid-state drives and dual-port NVMe solid-state drives It can only be used on devices with the same port mode correspondingly, and cannot be used in confusion. For example, a single-port NVMe solid state drive cannot be used on a storage device with a port mode of ...
