Problems solved by technology

[0005] An SSD with a single PCIe interface can only be inserted into one host, and can only be directly accessed by one host, while other hosts can only indirectly access the SSD. As a result, the access bandwidth of the host that indirectly accesses the SSD is small, and the access delay is large, so it cannot be quickly accessed. Well meet the needs of hosts for high performance, high bandwidth and large capacity of SSD

Abstract

The embodiment of the invention discloses a multi-interface solid state disk (SSD) as well as a processing method and a system thereof and relates to the field of communication. A plurality of host computers directly share and access an SSD, and the requirements of all the host computers on high performance, high bandwidth and large volume of the SSD are met. The multi-interface SSD comprises a plurality of interface control units, a command dispatching unit, a flash control unit and a flash chip, wherein each interface control unit corresponds to a communication interface; the interface control units receive operating commands through the communication interfaces; the command dispatching unit obtains the operating commands from the plurality of interface control units according to a dispatching rule, places the operating commands into a command queue, and takes out the operating commands to be transmitted to the flash control unit; and the flash control unit converts the operating commands into flash operating commands for operating the flash chip.

Description

technical field [0001] The invention relates to the communication field, in particular to a multi-interface solid-state hard disk and a processing method and system thereof. Background technique [0002] SSD (Solid State Disk, solid state drive) uses flash as the storage medium. Compared with traditional hard disks, it has the advantages of fast data access speed, shockproof and drop resistance, low power consumption, durability, no noise, and light and thin appearance. In some In special application scenarios, it has a good prospect of replacing traditional hard drives. Ordinary SATA (Serial Advanced Technology Attachment, serial advanced technology attachment) 3.0 interface SSD hard disk is limited by the bandwidth of SATA3.0 interface, and often cannot exert its maximum performance. The SSD with faster interconnection) interface has the advantages of larger capacity and higher performance, and can be well applied to fields with high capacity and performance requirements....
