The scene of embodiment of the present invention description is to more clearly illustrate the skill of the embodiment of the present invention
Art scheme, does not constitute the restriction for technical scheme provided in an embodiment of the present invention, and this area is common
Technical staff understands that, with the appearance of new scene, technical scheme provided in an embodiment of the present invention is for class
As technical problem, it is equally applicable.
As shown in figure 3, for a kind of flow of method for issuing I/O provided in an embodiment of the present invention is illustrated
Figure, including step S301-S303：
S301, issue I/O device obtain and parse the first service sub-system I/O patterns set letter
Breath.
S302, I/O mode setting information of the device according to the first service sub-system for issuing I/O, it is right
The I/O input interfaces of the first service sub-system registered in advance carry out I/O instantiations, obtain the first industry
The corresponding I/O streams of I/O input interfaces of business subsystem.
The I/O is flowed down and is issued the first service sub-system by S303, the device for issuing I/O.
Specifically, in embodiment of the present invention step S301：
First service sub-system can be specifically TGT in Fig. 2, LUN, volume, cache,
Extent, CKG, BDM or INI DRV, the embodiment of the present invention are not especially limited to this.
I/O mode setting informations can specifically include I/O pattern informations and I/O operation information.
Wherein, I/O pattern informations specifically can include initial sector, number of sectors, list I/O or
Sequential I/O or random I/O, I/O overall bandwidth, startup time or termination time etc., the present invention
Embodiment is not especially limited to this.
I/O operation information can specifically include startup or stopping etc..
It should be noted that why carry I/O operation information because：Each layering subsystem
I/O operation is independent, for convenience of independent control subsystem at all levels, therefore can carry I/O
Operation information.
Optionally, in the embodiment of the present invention, the I/O mode setting informations of the first service sub-system can be with
For the first service sub-system sets the information obtained after I/O patterns by way of configuration file.
Such as, the configuration file can be extensible markup language (English full name：extensible
Markup language, english abbreviation：) or other configurations template XML.
Or, the I/O mode setting informations of the first service sub-system can be logical for the first service sub-system
The mode for crossing order line sets the information obtained after I/O patterns.
Such as, the order line can be diagnosis (English name：diagnose).
It should be noted that any mode in for above two mode, firstly the need of by I/O
Pattern sets and arranges outputting standard, facilitates configuration file or order line to present.
It should be noted that above-mentioned is only exemplary to enumerate two kind of first I/O mould of service sub-system
The acquisition modes of formula configuration information.Certainly, the I/O mode setting informations of the first service sub-system also may be used
To obtain otherwise, the embodiment of the present invention is not especially limited to this.
Specifically, in embodiment of the present invention step S302：
I/O mode setting informations according to the first service sub-system, to first industry registered in advance
The I/O input interfaces of business subsystem carry out I/O instantiations, refer to actually, according to the first business subsystem
The I/O mode setting informations of system, instantiation output is carried out by certain algorithm to input pattern I/O,
I/O streams needed for producing.
Exemplary, if I/O pattern informations are sequential I/O, can be according to I/O address migration algorithm
In add algorithm carry out instantiation output to input pattern I/O, the I/O streams needed for producing.
Specifically, in embodiment of the present invention step S303：
After the corresponding I/O streams of I/O input interfaces are obtained, the I/O can be flowed down and issue I/O
Corresponding first service sub-system of input interface.
Exemplary, it is assumed that the first service sub-system is LUN, then can be by I/O
Flow down and issue LUN, for LUN provides I/O inputs；Assuming that the first service sub-system is volume,
I/O can then be flowed down and issue volume, for volume provides I/O inputs；Assuming that the first business
Subsystem is volume cache, then can flow down I/O and issue volume cache, is volume
Cache provides I/O inputs.
As can be seen that in the embodiment of the present invention, the device for issuing I/O can be provided for single subsystem
I/O be input into, or multiple subsystems simultaneously provide I/O input, the embodiment of the present invention to this not
Make specific restriction.
It should be noted that in the embodiment of the present invention, because the device producing ratio for issuing I/O is purer
Pure I/O streams, therefore, context and the I/O circulation relied on for subsystem I/O are changed to subsystem
, it is necessary to subsystem is safeguarded, the embodiment of the present invention is not made to have to this for actually used I/O structures
Body is limited.
Optionally, as shown in figure 5, in the embodiment of the present invention, obtaining and solving in the device for issuing I/O
Before analysing I/O mode setting informations (step S301) of the first service sub-system, can also include
Step S304：
S304, issue the device of I/O I/O input interfaces are registered to the first service sub-system.
That is, in the embodiment of the present invention, the first service sub-system can ask note to the device for issuing I/O
Volume I/O input interfaces, and then issue the device of I/O the registration I/O inputs of the first service sub-system are connect
Mouthful.
It is of course also possible to be that the device for issuing I/O registers I/O inputs to service sub-systems at different levels respectively
Interface, includes the first service sub-system in the service sub-systems at different levels, the embodiment of the present invention is not made to this
It is specific to limit.
It should be noted that the device for issuing I/O in the embodiment of the present invention can be specifically array control
Device processed, it is also possible to be integrated in a device in array control unit, it is also possible to be independently of array control
One device of device processed, the embodiment of the present invention is not especially limited to this.
Based on the method for issuing I/O provided in an embodiment of the present invention, in the embodiment of the present invention, I/O is issued
Device obtain and parse the I/O mode setting informations of the first service sub-system；And according to the first business
The I/O mode setting informations of subsystem, the I/O inputs to the first service sub-system registered in advance connect
Mouth carries out I/O instantiations, and the corresponding I/O of I/O input interfaces for obtaining the first service sub-system flows it
Afterwards, the I/O is flowed down and issues the first service sub-system.Because first service sub-system can be appointed
Meaning subsystem, therefore the method for issuing I/O is a kind of general method for issuing I/O, is solved
When existing array control unit side issues I/O, specific work can only be developed for a small number of particular subsystems
Tool, it is not general enough using limited, and maintenance cost problem higher, can be any single subsystem
System provides I/O inputs, or multiple subsystems provide I/O inputs simultaneously.Further, by
It is separate in the I/O inputs of subsystems at different levels, it is not necessary to rely on higher level's subsystem, therefore also accelerate
The convergence of subsystem checking.
