Description

Double nip real-time data sharing solid state hard disc
Technical field
The invention belongs to field of data storage, and in particular to a kind of double nip real-time data sharing solid state hard disc, its outfit Two-way interface, can allow two main equipment Real-Time Sharing hard disc datas.
Background technology
In field of data storage, solid state hard disc can only be typically simultaneously a main equipment service as slave unit, although have Part hard disk there may be two interfaces, but two interfaces can not be used simultaneously, but an interface is used as main interface When another interface as backup, only when main interface breaks down, can just start backup interface, it is ensured that storage system Reliability.
The content of the invention
(1) technical problem to be solved
The technical problem to be solved in the present invention is：How to provide a kind of to be simultaneously two solid state hard discs of main equipment service System.
(2) technical scheme
In order to solve the above technical problems, the present invention provides a kind of double nip real-time data sharing solid state hard disc, including：First SATA controller module, the first main control module, the second SATA controller module, the second main control module, data consistency treatment mould Block, mapping table memory module, data cache module, storage particle interface module, Nand Flash storage particles；
First SATA controller module is connected two main control devices respectively with the second SATA controller module；
First main control module and the second main control module are two parts of examples of identical function module, and SATA controls are docked respectively Device module processed and the second SATA controller module, receive two-way SATA instructions, and deposit by the maintenance of data consistency processing module Store up the mapping table in mapping table memory module；
Main control module is received after the instruction that SATA controller sends, it is necessary to when reading and writing the mapping table or data in downstream, First authorization requests are initiated to data consistency processing module；When data consistency processing module gives the right to use of downstream passages When giving main control module, the complete paired data of main control module, the read-write of mapping table update operation；
Data consistency processing module is responsible for safeguarding the uniformity of mapping table and data storage；When synchronization only one of which When main control module initiates request, the access limit of downstream data path is distributed to the main control module by data consistency module；When When synchronization has two-way main control module to initiate request, data consistency processing module is according to the dispatching method of poll by downstream number It is sequentially allocated to two main control modules according to the access limit of path；
Data cache module is used for depositing to be needed to write the data that Nand Flash store particle；
Storage particle interface module writes data into Nand Flash storage particles according to ONFI interface protocols；
Mapping table memory module storage main control module management Nand Flash store the data mapping tables of particle.
(3) beneficial effect
Compared with prior art, it can be simultaneously two solid state hard disk systems of main equipment service that the present invention is provided a kind of. When being used as common hard disc, main equipment can use whole memory spaces of solid state hard disc；When as real-time two-way solid-state When hard disk is used, hard disk operational pattern can be set, two pipeline equipments can in a different manner access the part of solid state hard disc or complete Portion's memory space.
Brief description of the drawings
Fig. 1 is double nip real-time data sharing solid state hard disc structure chart.
Specific embodiment
To make the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention Specific embodiment is described in further detail.
In order to solve the above technical problems, the present invention provides a kind of double nip real-time data sharing solid state hard disc, including：First SATA controller module, the first main control module, the second SATA controller module, the second main control module, data consistency treatment mould Block, mapping table memory module, data cache module, storage particle interface module, Nand Flash storage particles；As shown in Figure 1；
