Abstract
The invention discloses a kind of implementation method of SMART information monitorings, it is characterised in that increase sets abnormal collection module and exception reporting in hard disk controller；The abnormal collection module monitors the working condition of hard disk according to exceptional condition set in advance, and when exception occurs for hard disk and meets exceptional condition set in advance, hard disk controller notifies main frame and by abnormal conditions record in exception reporting；Main frame is only when receiving hard disk controller generation exception notice, and main frame just reads the exception reporting or SMART information of hard disk.To the regular read operation of SMART information when not occurring exception by cancelling hard disk, main frame is detected that brought performance loss is reduced to minimum to hard disk, the effect of actual raising host data throughput performance is reached.
Description
Technical field
The present invention relates to technical field of memory, more particularly to a kind of implementation method of SMART information monitorings.
Background technology
SMART (Self-Monitoring, Analysis, and Reporting Technology) refers to hard drive internal
Manager is to hard disk self-monitoring and analysis, and the state report generated includes hard disk health degree and abnormal information, passes through analysis
This report can for forecast analysis hard disk potential problems.Existing SATA SSD actively will not report hard disk to main frame Host and be good for
Kang Du/abnormal information is that SMART information inquiring commands are, it is necessary to Host is periodically judged by inquiring about SMART information
Legacy orders, so order needs exclusive SSD IO paths when issuing；Not due to this, order data amount is larger causes.Therefore
Host data throughput performances periodically will be influenceed on SMART inquiries.
The content of the invention
For disadvantages described above, present invention aims at how to reduce main frame to cause to provide IO because SMART information is read
How the occupancy in source, reduce the influence to Host data throughput performances.
To achieve these goals, the invention provides a kind of implementation method of SMART information monitorings, it is characterised in that
Increase sets abnormal collection module and exception reporting in hard disk controller；The abnormal collection module is according to exception set in advance
The working condition of condition monitoring hard disk, when exception occurs for hard disk and meets exceptional condition set in advance, hard disk controller is notified
Main frame simultaneously records abnormal conditions in exception reporting；Main frame is only when receiving hard disk controller generation exception notice, main frame
Just read the exception reporting or SMART information of hard disk.
The implementation method of described SMART information monitorings, it is characterised in that returned in the operational order of main frame access hard disk
Increase hard disk in value and enable mark extremely, when hard disk occurs abnormal, hard disk controller is by the behaviour of newest main frame access hard disk
Make hard disk enable mark extremely in order return value to be revised as enabling from invalid；Main frame checks hard disk and enabled extremely after mark,
The exception reporting or hair that hard disk is obtained by sending acquisition exception reporting instruction read SMART information commands acquisition SMART letters
Breath.
To the regular read operation of SMART information when the present invention does not occur exception by cancelling hard disk, by main frame to hard disk
The brought performance loss of detection is reduced to minimum, reaches the effect of actual raising host data throughput performance.
Brief description of the drawings
Fig. 1 is SATA SSD SMART abnormality processing schematic flow sheets.
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 is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is SATA SSD SMART abnormality processing schematic flow sheets, and system host Host is sent out on SATA SSD after electricity
Identify is sent to recognize hard disk order, whether detection SATA SSD have abnormal collection module and collect exception reporting Sense
Data Report functions, when detection SATA SSD support this function, then main frame will be somebody's turn to do by sending setting command in SATA SSD
Function is enabled, and notifies Host functions to enable while SATA SSD return to correct result, Host is normally carried out I/O operation.
1. SATA SSD during normal operation, are triggered by anomalous event or are periodically carried out SMART information in idle condition
Collect operation；
2. Host carries out normally read-write (I/O) operation to SATA SSD, without periodically inquiry hard disk health status；
3. SATA SSD SMART detect unusual condition, and such as remaining space is less than threshold value, notifies Sense Data
Report carries out abnormal conditions record；
4. abnormal collection module and exception reporting are set return command state after any order that Host is sent arrives
For SENSE DATA AVAI LABLE, to notify Host SSD to occur abnormal conditions；
5. Host detects return command state after SENSE DATA AVAILABLE, to directly transmit Request
Sense Data Ext orders directly can obtain the specific abnormal problem of hard disk from Sense Data Report modules；Or hold
Row is 6.；
6. Host directly transmits SMART Read Data orders and obtains SMART information progress SSD state analysis.
Above disclosed is only an embodiment of the present invention, can not limit the right model of the present invention with this certainly
Enclose, one of ordinary skill in the art will appreciate that all or part of flow of above-described embodiment is realized, and will according to right of the present invention
Made equivalent variations are sought, the scope that the present invention is covered is still fallen within.
Claims (2)
1. a kind of implementation method of SMART information monitorings, it is characterised in that increase sets abnormal collection mould in hard disk controller
Block and exception reporting；The abnormal collection module monitors the working condition of hard disk according to exceptional condition set in advance, works as hard disk
Generation exception and hard disk controller notifies main frame and by abnormal conditions record in abnormal report when meeting exceptional condition set in advance
In announcement；Main frame is only when receiving hard disk controller generation exception notice, and main frame just reads the exception reporting or SMART of hard disk
Information.
2. the implementation method of SMART information monitorings according to claim 1, it is characterised in that in the behaviour of main frame access hard disk
Make to increase hard disk enable mark extremely in order return value, when hard disk occurs abnormal, hard disk controller visits newest main frame
Ask that hard disk enable mark extremely is revised as enabling from invalid in the operational order return value of hard disk；Main frame checks hard disk to be made extremely
After identifying, obtain the exception reporting of hard disk by transmission acquisition exception reporting instruction or send out reading SMART information commands and obtain
Take SMART information.
