This absolute time is put into priority query, priority query is inserted by the priority of absolute time, keeps absolute time earliest
Element queue most before（top）Position, while safeguarding the mapping relations of an absolute time and task.When I/O resource request
When absolute time reaches, alert notification is sent to extraction module 340, processing is extracted by extraction module 340.If in queue
I/O resource request absolute time it is out of date, then discharge this element, and thread pool is transferred to execute.
With continued reference to Fig. 3, the control module 30 further includes：Extraction module 340, temporary queue management module 350 and
Two submit processing module 360.
Extraction module 340, for responding the alert notification, sequentially cycle extraction I/O resource is asked from the waiting list
The computing module 20 is sought and is committed to, when recalculating the waiting of I/O resource request of extraction by the computing module 20
Between.In practical applications, if calculating separately the stand-by period for IO speed (IOPS) and I/O bandwidth (BPS)（wait）, respectively
Two wait values of IOPS and BPS are obtained, its large one is taken in the two wait values（max_wait）, reached in the max_wait times
I/O resource request is extracted from waiting list to triggering extraction module 340 later.
Temporary queue management module 350, for be zero by the stand-by period recalculated I/O resource request be added it is interim
Queue, wherein the I/O resource request in the temporary queue asks identification information to be ranked up according to it.
Second submits processing module 360, for the I/O resource request in the temporary queue to be carried out submission processing.
In one embodiment of the application, if the stand-by period that computing module 20 calculates is zero, by the I/O resource
Request directly carries out submission processing；If the stand-by period that computing module 20 calculates is not zero, which is asked to be added
Preset waiting list.If waiting list is respectively set for read operation and write operation, extraction module 340 is successively from two teams
I/O resource request is taken out in row, one I/O resource request is extracted according to first in, first out sequence from queue every time, by calculating mould
Block 20 calculates its wait time to determine whether can currently submit again, should if the wait of I/O resource request is 0
I/O resource request is added in the temporary queue of setting, so sequentially extracts and calculation processing, until the I/O resource of extraction is asked
Until the wait asked is not 0.Extracted in two queues I/O resource request until wait be 0 after, will be in temporary queue
I/O resource request is ranked up according to the original order that request is submitted, so as to ensure the correctness of data.It finally will be interim
I/O resource request batch in queue is submitted to next stage storage system, and more newly-installed counter, timeslice are needed before submitting.
If still there is I/O resource request in waiting list, transfer to time management module 350 in the wait times and then
Secondary triggering waiting list management module 320 extracts I/O resource request from waiting list.If waiting list is empty, next IO is waited for
Resource request can trigger 320 resume module of waiting list management module again after waiting list is added.
It in one embodiment of the application, can be separately controlled for IO is read with IO is write, and can be to reading IOPS, writing
IOPS, it reads BPS, write the progress of BPS four indices individually control and combination control.Such as the disk A of a VM is provided with and writes IOPS
The upper limit is 100, and it is 1000 that entire NC equipment, which writes the IOPS upper limits, then A most multipotencys per second, which handle 100, writes IO, is owned on NC
All disks of VM are per second can only at most to handle 1000 IO.
Below with reference to Fig. 4, such as schemed according to the flow chart of the control method of the iostream of the application one embodiment
Shown in 4, the method includes at least：
In step S402, I/O resource request is received.
In one embodiment of the application, it can be a virtual machine to receive I/O resource request（VM）Disk is whole
A physical machine（NC）, following step is all equally executed for a VM disk or entire NC, to each disk to VM
IO performances, the overall performance of all VM is controlled on entire NC.
In step s 404, the stand-by period of the I/O resource request is calculated according to the resource metrics of setting.
First, setting receives the specific virtual machine of I/O resource request or the read/write I/O bandwidth of physical machine（Read and write BPS）Or
Person's read/write IO speed（Read and write IOPS）And current timeslice length limit（Such as 500ms）.According to current time stamp and set
Permitted first I/O resource of timeslice length computation current time stamp set, the first I/O resource are denoted as allow.First IO
Resource is to be currently able to the maximum resource quantity of scheduling, and in practical applications, the first I/O resource can be IO byte numbers and/or IO
Quantity.
Then, it is asked according to the I/O resource scheduled at that time of record（Including：Read and write byte number, IO quantity and current
I/O resource is asked）, the second I/O resource needed for current I/O resource request is calculated, the second I/O resource is denoted as expect.Described
Two I/O resources are the current I/O Request resources for it is expected processing, in practical applications, the second I/O resource can be IO byte numbers and/or
IO quantity.
The stand-by period of I/O resource request is set below by the size for comparing allow and expect（wait）, specifically：
If expect<=allow does not have to then be limited, and the setting wait times are 0；
If expect>Allow then needs to be limited, setting the wait times be (expect-allow)/IOPS or
BPS。
In practical applications, the stand-by period can be calculated separately according to IO quantity (IOPS) and IO byte numbers (BPS)
（wait）, two wait values for IOPS and BPS are respectively obtained, when thinking wait in the case where two wait values are all 0
Between be 0.
It is to be appreciated that I/O resource request is all uniformly distributed in timeslice by the wait times calculated every time, therefore can be with
Ensure that I/O Request is not in lingeringly substantially to shake.
In step S406, corresponding I/O resource request is controlled according to the stand-by period of calculating and carries out submission processing.Such as
The stand-by period for the I/O resource request that fruit calculates is zero, then I/O resource request is carried out submission processing, if currently receiving IO
Resource request is virtual machine, then asks I/O resource to be forwarded to corresponding physical machine by virtual level, if currently receiving IO
Resource request is physical machine, then the distributed storage resource pool of system is submitted to by the application program in physical machine；If meter
The stand-by period of the I/O resource request of calculation is not zero, then preset waiting list is added in I/O resource request.
It needs to be arranged and safeguard a waiting list in actual implementation, the IO that cannot temporarily handle is stored in waiting list
Resource request.Specifically, when being not zero the wait times for calculating I/O resource request, I/O resource request is added to described etc.
It waits in queue；In addition, after receiving I/O resource request in step S402, the pending IO such as judge whether to have in waiting list
Resource request, if do not had（I.e. waiting list is sky）Then follow the steps the processing of S404；If there is（I.e. waiting list is not
It is empty）Then the I/O resource received request is added in the waiting list.
In one embodiment of the application, read operation and write operation can be directed to, waiting list be respectively set, successively from
I/O resource request is taken out in two queues.One I/O resource request is extracted according to first in, first out sequence from waiting list every time,
It determines whether can currently submit by calculating its wait times again, if wait is 0, the interim team of setting is added
It in row, so sequentially extracts and calculation processing, until wait that the I/O resource of extraction is asked is not 0.Two queues
In extract I/O resource request until wait be 0 after, by temporary queue I/O resource request according to request identification information
（ID）It sorts from small to large, to ensure the original order of request submission, so as to ensure the correctness of data.It finally will be interim
Queue batch is submitted to next stage storage system, first more newly-installed counter and timeslice before submitting.
If still there is I/O resource request in waiting list, in wait times and then secondary triggering from waiting list
Extract I/O resource request.If there is no I/O resource request in waiting list（Waiting list is empty）, wait for that next I/O resource request adds
Process processing can be triggered again after entering waiting list.
Below with reference to Fig. 5, the control method of the iostream according to the embodiment of the present application is described in detail.As shown in figure 5,
The method includes the steps：
Step S502 receives I/O resource request.
Step S504 judges whether preset waiting list is sky, no to then follow the steps if so then execute step S506
S514。
Step S506 judges whether that resource is arranged（Time leaf length）The upper limit directly executes step if being not provided with the upper limit
Rapid S512, it is no to then follow the steps S508.
Step S508, when calculating the waiting of I/O resource request according to current time stamp and the timeslice length limit of setting
Between, circular please refers to description herein above, does not repeat herein.
Step S510 is withouted waiting for if being zero if the stand-by period, executes step S512；If the stand-by period is not zero,
It needs to wait for, executes step S514.
I/O resource request is submitted to next stage storage system, refresh counter and time before submission by step S512
Piece.
When carrying out submitting processing, according to the difference for the virtual machine or physical machine for receiving I/O resource request, have different
Submit processing mode.Specifically, the I/O resource of current I/O resource request VM asks to be forwarded to NC by virtual level, then by NC
Application program is submitted to the distributed storage resource pool of system.
I/O resource is asked that waiting list is added, and the stand-by period is arranged by step S514, when reaching the stand-by period, into
The submission processing of row I/O resource request.
The operating procedure of the present processes is corresponding with the structure feature of system, can be cross-referenced, no longer repeats one by one.
In conclusion according to the above-mentioned technical proposal of the application, the stand-by period asked by calculating I/O resource, and according to
