The invention realizes the dynamic adjustment of the read-write performance of video service information, thereby adjusting the read-write performance of all memory cells according to the read-write status of video service information, meeting read-write requirements of the equipment, improving the processing quality of the system for the read-write service of video service information and enhancing the reliability of the video service.

Description

The method of adjustment of read-write performance of video service information and equipment

Technical field

The present invention relates to communication technical field, particularly a kind of method of adjustment of read-write performance of video service information, equipment and system.

Background technology

In existing technical scheme, (Internet Protocol, IP) (Storage Area Network, video monitoring technical scheme SAN) has obtained using widely storage area network interconnection protocol Network Based.

The video monitoring technical scheme generally by camera, front end video encoder (Encoder, EC), (Video Management Client VC) forms for managing apparatus, rear end IP SAN and video management client.After the camera collection view data, coding and decoding video carries out the digital coding processed compressed with analog video data, video data is stored in the memory device again, and the VC client is carried out historical playing back videos.

As shown in Figure 1, be the control and the data flowchart of video monitoring technical scheme of the prior art.

Managing apparatus unified management EC, IP SAN and VC, the information interaction between above-mentioned each equipment realizes through the control signaling flow.

It is that reading and writing data flows from IP SAN reading video data that EC writes video data, VC to IP SAN.

The EC video data be stored in fixed logic resource in certain array of IP SAN (Logical UnitNumber, LUN) in, the LUN that different EC are corresponding possibly be distributed on the identical array, also possibly be distributed on the different arrays.The new EC that is created in of this LUN joins back completion in this scheme, and EC distributes corresponding LUN to the managing apparatus request, and to IP SAN request, IP SAN generally can preferentially be chosen on the more array of free space and create LUN managing apparatus again.

As shown in Figure 1, when the historical video data of EC1 was specified in VC 1 playback, VC1 was earlier to the managing apparatus request, and managing apparatus returns the information of the corresponding LUN1 of EC1 to VC1, and VC1 goes up reading of data from LUN1.

In realizing process of the present invention, the applicant finds that there is following problem at least in prior art:

It is fair play that prior art writes for each EC data, does not make EC performance differentiating and processing.But the EC kind is a lot, and the performance of every kind of model self is different, even if IP SAN provides identical disposal ability for each LUN, also can cause the low EC of self performance to be easier to occur writing the packet loss phenomenon.The performance of whole proposal can receive the direct influence of the minimum EC of performance, thereby influences the performance performance of whole proposal.

Prior art writes for VC playback and EC and does not do wholely to consider.EC occurs through regular meeting and write the phenomenon that the VC replay image pauses under the normal situation, this is because IP SAN is enough fast to the write operation that EC returns, but IP SAN is slow excessively to the read operation speed that VC returns, and is unable to catch up with the required speed of VC playback, causes image to pause.

Embodiment

Of background technology; Existing video traffic storage and read in the mechanism division and can not adjust according to the concrete performance requirement of equipment to resource; Can not satisfy the concrete business demand in each equipment read-write operation; Therefore and possibly cause losing of video service information, influence video traffic processing quality, and and then influence user's experience.

Technical scheme of the present invention is set up a cover communication mechanism between video encoder (EC), management equipment (Manager), memory device (IP SAN) and videoconference client (VC), be used for control performance dynamic adjustments process.Send performance adjustment request or professional normal notice, management equipment to steps such as IP SAN transmitting control message, IP SAN operation internal performance adjustment processes through EC or VC; Write performance between the many EC of balance; Or balance VC reads and the performance of EC between writing, and writes packet loss problem and EC and writes under the normal condition problems such as VC replay image pause thereby solve low configuration EC.

The present invention proposes a kind of method of adjustment of read-write performance of video service information; Be applied to comprise in the system of a plurality of video encoders, a plurality of videoconference client, a memory device and a management equipment; Wherein, Comprise a plurality of memory cell in the memory device, each memory cell is corresponding with each video encoder respectively, stores the video service information that each video encoder generates; Preserve the corresponding relation of memory cell and video encoder in the management equipment, and memory device is carried out readwrite performance adjustment control.

As shown in Figure 2, the schematic flow sheet for the method for adjustment of a kind of read-write performance of video service information proposed by the invention specifically may further comprise the steps:

What step S201, memory device receiving management equipment sent adjusts request to one or more performances of the memory cell of raising write performance or reading performance that need.

Wherein, before this step is carried out, also comprise and trigger the process that management equipment is sent performance adjustment request, specifically comprise following two kinds of situation:

The triggering flow process of situation one, raising write performance.

When the video encoder judgement self occurred writing the situation of loss of data, video encoder sent write performance to management equipment and improves request.

Management equipment confirms that according to the corresponding relation of memory cell and video encoder needs improve the memory cell of write performance, and sends the performance adjustment request to the memory cell that needs the raising write performance to memory device.

The triggering flow process of situation two, raising reading performance.

When videoconference client judged that the situation of reading of data pause appears in the video service information that self reads a video encoder, the reading performance that videoconference client sends to video encoder to management equipment improved request.

Management equipment confirms that according to the corresponding relation of memory cell and video encoder needs improve the memory cell of write performance, and sends the performance adjustment request to the memory cell that needs the raising reading performance to memory device.

Step S202, memory device judge that the pairing memory cell of performance adjustment request that receives is to need to improve write performance or reading performance.

When judging that this memory cell need improve write performance, change step S203 over to;

When judging that this memory cell need improve reading performance, change step S204 over to.

Step S203, memory device suppress the write performance and/or the reading performance of other memory cell, or suppress the reading performance of this memory cell self, and raising needs the write performance of the memory cell of raising write performance.

Step S204, memory device suppress the write performance and/or the reading performance of other memory cell, or suppress the write performance of this memory cell self, and improve the reading performance that this need improve the memory cell of reading performance.

In concrete application scenarios; Can also comprise a plurality of storage arrays in the memory device; And comprise one or more memory cell in the storage array respectively; The write performance of inhibition that step S203 and step S204 are proposed or raising memory cell or the treatment step of reading performance, specifically realize through following mode:

Mode one, memory device reduce or improve input and output (Input/Output, IO) priority of processing threads of the storage array under the memory cell.

This mode is applicable to all raisings of the readwrite performance of memory cell in the storage array; Improve the priority of input processing threads; With the write performance that improves whole memory cell in this storage array; Improve the priority of output processing threads, with the reading performance that improves whole memory cell in this storage array.

Mode two, memory device reduce or writing buffer memory or reading buffer memory of the affiliated storage array of memory cell distributed in increase.

This mode is equally applicable to all raisings of the readwrite performance of memory cell in the storage array; Increase the buffer memory of writing of storage array; With the write performance that improves whole memory cell in this storage array; Increase the buffer memory of reading of storage array, with the reading performance that improves whole memory cell in this storage array.

Mode three, memory device reduce or increase distributes to writing buffer memory or reading buffer memory of memory cell.

This mode is applicable to the raising that directly is directed against the individual readwrite performance of memory cell, increases the buffer memory of writing of memory cell, with the write performance that improves this memory cell, increases the buffer memory of reading of memory cell, with the reading performance of this memory cell of raising.

In the application scenarios of reality; Three kinds of above-mentioned modes not only are confined to independently adjust application; Also can carry out the combination of multiple mode according to concrete system's setting and use, to reach more accurately and to adjust effect flexibly, such variation belongs to protection scope of the present invention equally.

Need further be pointed out that; If through after the adjustment once for write performance or reading performance; When the adjustment result still can not satisfy the video traffic needs of video encoder or videoconference client; This video encoder or videoconference client can continue to initiate to promote the request of write performance or reading performance, and the performance adjustment request to same memory cell is initiated to memory device in management equipment identification back, promptly carries out following steps S205:

What step S205, memory device receiving management equipment sent asks to the current performance adjustment that has been in the memory cell of performance boost state.

Again return step S202; Get into the new one performance adjustment process of taking turns; Because the current performance boost state that has been in of this memory cell is so memory device repeats the adjustment flow process to this memory cell; Strengthen the write performance of the current memory cell that is suppressed performance and/or the inhibition degree of reading performance, and strengthen the write performance of the current memory cell that is raised performance or the lifting degree of reading performance.

Above-mentioned cyclic process can repeat, and when performance adjustment result satisfies the video traffic needs of video encoder or videoconference client, carries out follow-up step S205, finishes the performance adjustment to this memory cell.

Concrete processing procedure is following:

Notice is accomplished in the adjustment that step S206, memory device receiving management equipment send.

Step S207, memory device are preserved the adjustment completion and are notified the write performance of pairing each memory cell or the adjustment result of reading performance.

Preservation through above-mentioned adjustment result is handled, and make the result of current adjustment can be able to preserve, thereby the video traffic in the assurance system normally carries out.

Need further be pointed out that; In order to guarantee the normal operation of system; Need avoid the Infinite Cyclic of performance adjustment process, and because adjust repeatedly the resource waste that causes promptly to the influence of normal video traffic, therefore; Can limit the number of times of adjustment process circulation; Mode through the adjustment frequency threshold value is set limits, and when reaching set adjustment frequency threshold value to the adjustment cycle-index of same memory cell, no matter whether current performance adjustment result satisfies the video traffic needs of video encoder or videoconference client; Memory device all will directly finish the adjustment process to this memory cell, and such variation belongs to protection scope of the present invention equally.

And in the application scenarios of reality; The trigger mechanism of management equipment transmission adjustment completion notice can be normal notice of business that receives video encoder or videoconference client transmission among the step S205; After the normal transmission of notifying then relates to and accomplishes above-mentioned performance adjustment operation to business; In video encoder or videoconference client side, the inspection process to performance adjustment result specifically is divided into following two kinds of situation:

(1) inspection process of write performance

After the write performance of the pairing memory cell of video encoder is enhanced, if video encoder judges that from the situation that loss of data in preset Check-Out Time, do not occur writing video encoder sends professional normal notice to management equipment.

When management equipment receives professional normal notice of the pairing video encoder transmission of the memory cell that is enhanced write performance; Management equipment is according to the corresponding relation of memory cell and video encoder; Confirm and business normally to notify pairing memory cell; And send the adjustment that is directed against this memory cell to memory device and accomplish notice, make memory device preserve the adjustment result that the write performance of notifying pairing each memory cell is accomplished in this adjustment.

(2) inspection process of reading performance

After the reading performance of the pairing memory cell of video encoder is enhanced; The situation that reading of data is paused do not occur if videoconference client is judged from the video service information that in preset Check-Out Time, reads video encoder, videoconference client sends professional normal notice to management equipment.

When professional normal notice that management equipment receives that the videoconference client of the video service information that reads the memory cell that is enhanced reading performance sends; Management equipment is according to the corresponding relation of memory cell and video encoder; Confirm and business normally to notify pairing memory cell; And send the adjustment that is directed against this memory cell to memory device and accomplish notice, make memory device preserve the adjustment result that the reading performance of notifying pairing each memory cell is accomplished in this adjustment.

Need further be pointed out that, be a sense cycle of presetting mentioned Check-Out Time in above-mentioned inspection process; Be a time interval that is used to detect performance adjustment effect that after the performance adjustment, picks up counting, if in this time interval, writing or read all of video service information normally carried out; Then be regarded as the performance adjustment effectively, can send professional normal notice to management equipment, otherwise; If in this time interval, writing or read still of video service information has problems, and it is invalid then to be regarded as the performance adjustment; Continuation is sent performance adjustment request to management equipment, continues the readwrite performance of memory cell is adjusted.

In actual application; Above-mentioned time zero Check-Out Time can be to adjust the entry-into-force time accurately (this kind situation needs the performance adjustment feedback of memory device or management equipment; Be not described in detail in this); Also can be to identify the other times point that adjustment is carried out; Such as: video encoder or videoconference client send the time of performance adjustment request, in order to improve timely precision, can also estimate by sending the time of delay that the performance adjustment asks the performance adjustment to come into force; Sending performance adjustment request and picking up counting through the time point after above-mentioned time of delay, the timing rule of concrete Check-Out Time and the variation of preseting length do not influence protection scope of the present invention.

Above-mentioned is the performance adjustment flow process of complete read-write performance of video service information; But, the cost of performance adjustment is reduced to prerequisite because being write performance with other memory cell or this memory cell in the memory device; Therefore, the current performance that the memory cell of write performance possibly occur being lowered can not satisfy the situation that video traffic requires, in this case; Need adjust again existing adjustment state; Promptly recover the performance of the current memory cell that is lowered performance, and select other memory cell to substitute, the scheme of specifically adjusting is following:

Receive the performance adjustment request of the requirement raising write performance that is directed against memory cell of management equipment transmission when memory device; And when judging that the pairing memory cell of this performance adjustment request is current and being in repressed performance adjustment state; Memory device recovers to be suppressed the write performance of the memory cell of write performance, and suppresses the write performance of another other memory cell different with the memory cell of the memory cell of current raising write performance or inhibition write performance.

Need to prove; The current operation that is in repressed performance adjustment state of the pairing memory cell of this performance adjustment request of above-mentioned judgement can make memory device carry out; Can be that management equipment is carried out, such variation influence protection scope of the present invention yet.

Need further be pointed out that; In order better to realize the adjustment effect; Situation for the write performance of current raising memory cell; Can preferentially select to suppress to be positioned at the write performance of other memory cell of different storage arrays with memory cell that improves write performance and the memory cell that suppresses write performance; Accordingly, for the situation of the reading performance of current raising memory cell, can preferentially select to suppress to be positioned at the write performance of other memory cell of identical storage array with memory cell that improves reading performance and the memory cell that suppresses write performance; But this is preferred embodiment a kind of; As long as can realize treating the write performance of adjustment memory cell or the raising of reading performance through the write performance that suppresses certain memory cell, whether corresponding memory cell is positioned at identical storage array, can't influence protection scope of the present invention.

For technical scheme proposed by the invention more clearly is described; The present invention has also proposed a kind of method of adjustment of read-write performance of video service information from the angle of management equipment; Be applied to equally comprise in the system of a plurality of video encoders, a plurality of videoconference client, a memory device and a management equipment, wherein, comprise a plurality of memory cell in the memory device; Each memory cell is corresponding with each video encoder respectively; Store the video service information that each video encoder generates, preserve the corresponding relation of memory cell and video encoder in the management equipment, and memory device is carried out readwrite performance adjustment control.

As shown in Figure 3, for the present invention has proposed a kind of method of adjustment of read-write performance of video service information from the angle of management equipment, specifically may further comprise the steps:

The write performance that step S301, management equipment receiver, video encoding device send improves request, or the reading performance that videoconference client sends improves request.

Wherein, write performance improves the triggering flow process that request or reading performance improve request and in the step S201 of preamble, specifies, at this repeated description no longer.

Step S302, management equipment are according to the memory cell of preserving and the corresponding relation of video encoder, and the identification write performance improves request or reading performance improves the pairing memory cell that needs to improve write performance or reading performance of request.

Step S303, management equipment are sent the performance adjustment request to the memory cell that needs raising write performance or reading performance to memory device, make memory device carry out corresponding performance adjustment.

For concrete application scenarios, after memory device improved the write performance or reading performance of the said memory cell that needs to improve write performance or reading performance, technical scheme proposed by the invention also further comprised:

The professional normal notice that step S304, management equipment receiver, video encoding device or videoconference client send.

Wherein, the triggering flow process of professional normal notice and adjust the product test flow process accordingly and in preamble, specify is at this repeated description no longer.

Step S305, management equipment are according to the memory cell of preserving and the corresponding relation of video encoder, and identification services is normally notified pairing memory cell.

Step S306, management equipment are sent to this business to memory device and are normally notified the adjustment of pairing memory cell to accomplish notice, make memory device preserve corresponding adjustment result.

Can not satisfy under the situation that video traffic requires accordingly in the current performance of the memory cell that is lowered write performance, also consistent to the flow process that existing adjustment state is adjusted again with above-mentioned explanation, repeat no more at this.

Compared with prior art, the present invention has the following advantages:

Below in conjunction with concrete application scenarios, specific embodiments of the present invention is described.

As shown in Figure 4; Be the structural representation of the application scenarios of a kind of video service information storage proposed by the invention, this application scenarios can be realized video monitoring service, comprises the collecting device of a plurality of video encoders (EC) as video monitoring information; Generate corresponding video service information (monitor data); And in IP SAN, store in the corresponding memory cell (LUN), in IP SAN, each LUN belongs to different storage arrays (array A, B, C respectively ...).

In this application scenarios, when a video encoder finds that the packet loss phenomenon appears in the video service information of self in storing process, improve flow process with starting write performance proposed by the invention, particular flow sheet is as shown in Figure 5, may further comprise the steps:

Step S501, EC1 detect self and packet loss occurs, just send write performance to management equipment and improve request, require " improving the EC1 write performance ".

The possibility that this situation occurs is that the EC1 configuration is lower, and it is littler than other EC to require to write the IO response time, and under the IP SAN initial situation to all arrays/LUN fair play.

The situation that the EC1 packet loss occurs, the speed of promptly representing the EC1 storage is unable to catch up with EC1 the image that receives is carried out speed of coding.

Step S502, management equipment are sent write performance to IP SAN and are improved request, require to improve LUN1 and handle the performance that writes.

Need to prove.In this step; The identifying that also comprises the purpose memory cell of performance adjustment; Owing to store the corresponding relation between EC1 and the LUN1 in the management equipment; So, when management equipment receives the request of the write performance that requires raising EC1, can identify and need carry out the actual LUN1 of being that write performance promotes.

Step S503, IP SAN start the internal performance adjustment process, improve the write performance of LUN1.

Concrete regulative mode is to select the LUN3 write performance to be suppressed, and the write performance of LUN1 is promoted being positioned at the LUN3 (being positioned at array B) on the different arrays with LUN1 (being positioned at array A).

And further, the method for inhibition or lifting write performance can comprise:

(1) IP SAN internal processes is regulated the IO processing threads priority of different arrays;

(2) IP SAN is the buffer memory of writing that different arrays are redistributed different capabilities;

(3) IP SAN redistributes the buffer memory of writing of different capabilities for Different L UN in the LUN aspect.

In concrete application scenarios, specifically adopt the method for which kind of inhibition or lifting write performance not influence protection scope of the present invention.

Step S504, property regulation are accomplished, and behind the scheme stable operation certain hour, EC1 judgement self packet loss phenomenon solves, and then EC1 sends the notification message (being that aforesaid business is normally notified) of " packet loss solves " to management equipment.

If step S505 management equipment receives the notification message that EC1 sends, and other EC (particularly EC3) write all normally, and then management equipment is sent adjustment to IP SAN and accomplished notice, preserves current performance adjustment state.

After step S506, IP SAN receive adjustment completion notice, preserve current performance adjustment state.

Preservation current performance adjustment state described here; Specifically refer to preserve the performance adjustment state of current related memory cell; Wherein, Comprise being enhanced writing or the performance adjustment state of the memory cell of reading performance, and the cost that improves as performance and be suppressed the current performance adjustment state of the memory cell of write performance.

Above-mentioned flow process has promoted the write performance of EC1 through suppressing the write performance of EC3, guaranteeing that EC3 writes under the normal situation, has solved the packet loss phenomenon of EC1.

But in this process, the write performance that EC3 may occur does not reach the situation that video traffic requires, and in the case, need adjust existing adjustment state again, and is as shown in Figure 6, may further comprise the steps:

Wherein, the handling process of step S601 to the handling process of step S603 and step S601 to step S603 is consistent, at this repeated description no longer.

After step S603 accomplishes, after promptly IP SAN has accomplished internal performance and regulates, if EC3 detects in self the ablation process of video service information the packet loss phenomenon takes place.To carry out following treatment step:

Step S604, EC3 detect self and packet loss occurs, send write performance adjustment request to management equipment, require " improving the EC1 write performance ".

In such cases, the reason of packet loss phenomenon is that IP SAN has carried out the write performance inhibition to LUN3.

Step S605, management equipment are according to inner preservation state information; Judge the current property regulation state that is in of the pairing LUN3 of EC3 of learning, so, after the request that receives EC3; Send the write performance recovery request to IP SAN, require " recovering the write performance of LUN3 ".

If whether be in the judgement of adjustment state for memory cell carried out by IP SAN, then this step is directly sent the performance adjustment request to LUN3 to IP SAN, requires to improve write performance and gets final product, and such variation belongs to protection scope of the present invention equally.

Step S606, IP SAN judge the current internal performance adjustment state that is in, and then after the write performance recovery request that receives " write performance that recovers LUN3 ", carry out the write performance of memory cell again and regulate.

In concrete application scenarios, it is following to carry out the process that the write performance of memory cell regulates again:

(1) recovers the LUN3 write performance, promptly recover the IO processing threads priority of array B, or recover array B or the spatial content of LUN3 in writing buffer memory;

(2) select the next one can repressed LUN, for example select to be in the LUN4 resource on the different arrays (array C) with LUN1;

(3) LUN4 is carried out the inhibition of write performance.

Step S607, property regulation are accomplished, and behind the scheme stable operation certain hour, EC1 judgement self packet loss phenomenon solves, and then EC1 sends the notification message (being that aforesaid business is normally notified) of " packet loss solves " to management equipment.

If step S608 management equipment receives the notification message that EC1 sends, and other EC (particularly EC3, EC4) write all normally, and then management equipment is sent adjustment to IP SAN and accomplished notice, preserves current performance adjustment state.

After step S609, IP SAN receive adjustment completion notice, preserve current performance adjustment state.

On the other hand, as shown in Figure 7, the structural representation of the application scenarios that reads for a kind of video service information proposed by the invention; This application scenarios can be realized video monitoring service; Comprise the collecting device of a plurality of video encoders (EC), generate corresponding video service information (monitor data), and in IP SAN, store in the corresponding memory cell (LUN) as video monitoring information; In IP SAN; Each LUN belongs to different storage arrays (array A, B, C respectively ...), also comprising the fetch equipment of a plurality of videoconference clients (VC) as video monitoring information, the LUN in IP SAN reads video monitoring information.

In this application scenarios, find the video service information of self when videoconference client and reading when the replay image break occurring in the process that improve flow process with starting reading performance proposed by the invention, particular flow sheet is as shown in Figure 8, may further comprise the steps:

Step S801, VC1 detect and the image break occurs when the historical video data that playback EC1 stores, and just send reading performance to management equipment and improve request, require " improving the video data reading performance that EC1 stores ".

It is frequent that the possibility that this situation occurs is on logical resource LUN1 or array A, to write IO, can influence on it to read the IO response slower, VC is unable to catch up with the requirement of VC replay image frame per second from the speed of LUN1 reading of data, replay image will occur and pause.

Step S802, management equipment are sent reading performance to IP SAN and are improved request, require to improve LUN1 and handle the performance that reads.

In this step; The identifying that also comprises the purpose memory cell of performance adjustment; Owing to store the corresponding relation between EC1 and the LUN1 in the management equipment; So, when management equipment receives the request of the reading performance that requires raising EC1, can identify and need carry out the actual LUN1 of being that reading performance promotes.

Step S803, IP SAN start the internal performance adjustment process, improve the reading performance of LUN1.

Because suppress the write performance of LUN1, it is the most obvious to improve the effect that LUN1 reads, so concrete regulative mode is preferentially selected LUN1 to carry out write performance to suppress, to promote the reading performance of LUN1 itself.

The concrete inhibition or the method for lifting are:

IP SAN internal processes is regulated the IO thread priority of LUN1, promptly improves and reads the IO thread priority, reduces and writes the IO thread priority.

Need point out further that this flow process is regulated from the LUN aspect, also can consider to regulate, promptly sound out raising array A earlier and read the IO thread priority, reduce array A and write the IO thread priority, if unsuccessful array B again carries out exploratory adjustment joint from the RAID aspect.

At this moment, if EC1 detects self packet loss appears, then execution in step S804.

Step S804, EC1 detect packet loss, send request to management equipment, require " improving the EC1 write performance ".

In such cases, the reason of packet loss phenomenon is that IP SAN has carried out the write performance inhibition to LUN1.

Step S805, management equipment are according to inner preservation state information; Judge the current property regulation state that is in of the pairing LUN1 of EC1 of learning, so, after receiving the EC1 request; Send the write performance recovery request to IP SAN, require " recovering the write performance of LUN1 ".

If whether be in the judgement of adjustment state for memory cell carried out by IP SAN, then this step is directly sent the performance adjustment request to LUN1 to IP SAN, requires to improve write performance and gets final product, and such variation belongs to protection scope of the present invention equally.

Step S806, IP SAN judge the current internal performance adjustment state that is in, and then after the write performance recovery request that receives " write performance that recovers LUN1 ", carry out the write performance of memory cell again and regulate.

(1) recover the LUN1 write performance, that promptly recovers LUN1 writes IO processing threads priority;

(2) select the next one can repressed LUN, for example select the LUN2 resource on the identical array;

(3) LUN2 is write inhibition.

Step S807, property regulation are accomplished, and behind the scheme stable operation certain hour, VC1 judges that the replay image pause solves, and then VC1 sends the notification message (being that aforesaid business is normally notified) of " replay image pauses and solves " to management equipment.

If step S808 management equipment receives the notification message that VC1 sends, and other EC (particularly EC1, EC2) write all normally then management equipment and send adjustment to IP SAN and accomplish notice, preserve current performance adjustment state.

After step S809, IP SAN receive adjustment completion notice, preserve current performance adjustment state.
