Abstract
The invention discloses a kind of method for lifting the solid storage device life-span, it is characterised in that increases the cold and hot type of data in the order that main frame is issued to solid-state hard disk controller；Memory space is divided into cold data area and dsc data area by solid state hard disc, and the cold and hot type selecting of data that solid-state hard disk controller carries according to the order received writes data into corresponding data field.Shown by user and inform that solid storage device to be write the cold and hot type of data, the cold and hot type information of data that solid storage device carries according to order, writes data into different zones, is kept completely separate cold and hot data, so as to lift the efficiency of garbage reclamation, extend the solid storage device life-span.
Description
Technical field
The present invention relates to storage device control field, more particularly to a kind of method for lifting the solid storage device life-span.
Background technology
Solid storage device would generally divide user data cold data and the class of dsc data two.So-called cold data refers to write
The data that will not be just updated substantially after entering；Dsc data then refers to the data of meeting frequent updating.Solid storage device distinguish this two
Class data are in order to which this two classes data separating is stored, to reduce data-moving unnecessary in garbage collection procedure.
At present using in the system of solid storage device, the identification of cold and hot data is typically to be completed by solid storage device.
But identifying cold and hot data by solid storage device, not only cost is high, and the accuracy identified cannot guarantee that.
The content of the invention
For disadvantages described above, the present invention seeks to how reduce to write amplification caused by garbage collection procedure, lifting solid-state is hard
The disk life-span.
A kind of method for lifting the solid storage device life-span is proposed in order to solve the problem above present invention, it is characterised in that
Increase the cold and hot type of data in the order that main frame is issued to solid-state hard disk controller；Memory space is divided into cold by solid state hard disc
Data field and dsc data area, the cold and hot type selecting for the data that solid-state hard disk controller carries according to the order received is by data
Cold data area and dsc data area corresponding to writing by type, realize that cold data and dsc data are separated and stored respectively.
The method in described lifting solid storage device life-span, it is characterised in that be additionally provided with the solid-state hard disk controller
Aid in cold and hot data evaluation module, the cold and hot data evaluation module is with data page position unit, each number in record unit time
The number being accessed according to page, the cold and hot type of data of each data page is evaluated according to the number of access；Auxiliary is helped into cold and hot number
The cold and hot type of data that the data cold and hot type assessed according to evaluation module carries when being issued from main frame takes different weights to enter respectively
The cold and hot type of row comprehensive descision data.
The present invention informs that solid storage device to be write the cold and hot type of data, solid storage device by being shown by user
The cold and hot type information of data carried according to order, writes data into different zones, is kept completely separate cold and hot data, so as to be lifted
The efficiency of garbage reclamation, extend the solid storage device life-span.
Brief description of the drawings
Fig. 1 is the handling process for the write order for carrying cold and hot information.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
In host side, the owner of application program or system program as data, it can provide it with accurate and to be write
Enter the cold and hot type of data, as the promoter for writing action, the cold and hot information of data is just carried in the write request of most initial, is driven
Dynamic program inherits the information transmission to solid storage device in write order.Solid storage device then according to the cold and hot information of data from
Different address pool distribution addresses, they is write different regions, reaches the purpose of cold and hot data separating.Fig. 1 is that carrying is cold
The handling process of the write order of thermal information；In main frame HOST by application program or system program according to the characteristics of its application data it is first
Judge the cold-hot characteristic of its data, the write request with cold and hot mark is submitted to driver by application program or system program；
Driver sends the write order with cold and hot mark into solid storage device.The master controller of solid storage device, according to connecing
The write order received is decomposed, and is decomposed into the accessible r/w cell of FLASH controller, while select according to the cold and hot type of data
Select the address pool difference FLASH addresses of the cold and hot type of difference set in advance, and generate write request, and submit write request to
FLASH controller, write data into by FLASH controller in the FLASH addresses of distribution, handle the r/w cell of next decomposition,
Until all r/w cells decomposed have all been handled, this write operation is completed.
The above disclosed interest field for being only an embodiment of the present invention, sheet can not being limited with this certainly,
One of ordinary skill in the art will appreciate that all or part of flow of above-described embodiment is realized, and according to the claims in the present invention institute
The equivalent variations of work, still fall within the scope that the present invention is covered.
Claims (2)
- A kind of 1. method for lifting the solid storage device life-span, it is characterised in that be issued to the life of solid-state hard disk controller in main frame Increase the cold and hot type of data in order；Memory space is divided into cold data area and dsc data area, solid state hard disc control by solid state hard disc Device cold data area and heat according to corresponding to the cold and hot type selecting for the data that the order received carries writes data by type Data field, realize that cold data and dsc data are separated and stored respectively.
- 2. the method in lifting solid storage device life-span according to claim 2, it is characterised in that the solid state hard disc control The cold and hot data evaluation module of auxiliary is additionally provided with device processed, the cold and hot data evaluation module records unit with data page position unit The accessed number of each data page in time, the cold and hot type of data of each data page is evaluated according to the number of access；Will The cold and hot type of data that the data cold and hot type for helping cold and hot data evaluation module to assess carries when being issued with main frame takes respectively Different weights carry out the cold and hot type of comprehensive descision data.
