Abstract

The invention discloses a system for supporting a PCIE signal of a NVMe protocol, which comprises a hard disk back plate and a switching module, a first connector, a second connector and a hard disk connector which are arranged on the hard disk back plate; an output end of the hard disk connector is connected with an input end of the switching module and used for outputting the switching signal sent by a user to the switching module; an output end of the switching module is connected to an input end of a first connector and an input end of a second connector, an output end of the first connector is connected with the first hard disk, and an output end of the second connector is connected with the second hard disk; the switching module is used for switching to the PCIEX4 channel according to the switching signal so as to realize its connection with the first connector, or switching to two PCIEX2 channels to realize the connection between the first connector and the second connector. When a storage system is developed, the PCEIX4 interface and PCIEX2 dual-interface can be satisfied by the same one hard disk back plate; therefore, the system reduces the development cost and is good for the market competition.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a system supporting NVMe protocol PCIE signals. Background technique [0002] NVMe (Non-Volatile Memory express, non-volatile memory) is a high-speed transmission protocol specification used to replace the AHCI (Serial ATA Advanced Host Controller Interface, Serial ATA Advanced Host Controller Interface) transmission protocol, which is specifically for PCIE ( Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) "optimized driver" for bus customization. [0003] With the emergence of the NVMe protocol, the storage system has also begun to load the high-speed SSD (Solid State Disk, solid state drive) of the NVMe protocol. The latest NVMe protocol supports single-port and dual-port signal transmission, that is, single-port NVMe and dual-port NVMe. When single-port NVMe is used for signal transmission, the interface is PCIEX4 interface, and...
