The resource pool 110 of described memory device is used for depositing exchange resource, and is that starter resource module 120 and object machine resource module 130 distribute exchange resource.Particularly, described memory device obtains memory device and sends and receive the required exchange resource amount of IO request, according to the required exchange resource amount of described transmission IO request, be starter resource module 120 from resource pool 110, according to the required exchange resource amount of described reception IO request, be that object machine resource module 130 distributes exchange resource from resource pool 110.For example, memory device obtains the interior IO of transmission of the default very first time and asks concurrent number of times and receive IO to ask concurrent number of times, ask concurrent number of times and receive IO to ask the required exchange resource amount of concurrent number of times difference to obtain sending IO respectively, and asking the required exchange resource of concurrent number of times from resource pool 110 for starter resource module 120 distributes described transmissions IO, described reception IO asks the required exchange resource of concurrent number of times for 130 distribution of object machine resource module.
Described starter resource module 120 is used for providing memory device to send the required exchange resource of IO request to remote equipment, and namely the exchange resource deposited of starter resource module 120 only is used for the INI business model.Described object machine resource module 130 is used for providing and receives the required exchange resource of IO request that remote equipment sends, and namely the exchange resource deposited of object machine resource module 130 only is used for the TGT business model.
Described memory device is sending the IO request when (needing operation INI business model) to remote equipment, preferentially to starter resource module 120 application exchange resources, receiving the IO request that remote equipment sends when (needing operation TGT business model), preferentially to object machine resource module 130 application exchange resources.The memory device application can be carried out the mutual of INI or TGT business with described remote equipment behind exchange resource.After this business was finished, the exchange resource that memory device takies this business was discharged into corresponding resource module, i.e. starter resource module 120 or object machine resource module 130.
If memory device applies for less than exchange resource that to starter resource module 120 or object machine resource module 130 then memory device is to resource pool 110 application exchange resources.If memory device to exchange resource, then carry out the mutual of this business with described remote equipment, and after this business was finished, the exchange resource that this is professional discharged back resource pool 110 to resource pool 110 applications.If memory device less than exchange resource, then returns application less than the information of exchange resource to resource pool 110 applications, at this moment, memory device can't carry out the mutual of this business with described remote equipment, occurs unusual.
The application's embodiment is according to sending the required stock number of IO request, distribute exchange resource from resource pool for the starter resource module, distribute exchange resource according to receiving the required stock number of IO request for the object machine resource module, the exchange resource of starter resource module and object machine resource module is separate, and the required exchange resource of INI business model is provided by described starter resource module, the required exchange resource of TGT business model is provided by the object machine resource module, make that the exchange resource of INI and two kinds of business models of TGT is separate, avoided the exchange resource competition occurring with INI business model and TGT business model in mouthful pattern.Simultaneously, therein a kind of professional appearance unusually, when causing corresponding resource module exchange resource to exhaust, also can not influence the application of another kind of operation exchange resource, make another kind of business normally to move, improve the reliability of memory device.
See also Fig. 2, Fig. 2 is the process flow diagram of the application's exchange resource management method one embodiment.Described exchange resource management method may further comprise the steps:
Step S201: memory device obtains to send and receive the required exchange resource amount of IO request respectively.
Memory device has with a mouthful attribute, can move INI and TGT business model.Memory device sends the IO request to remote equipment when operation INI business model, and the application exchange resource, when operation TGT business model, receives the IO request that remote equipment sends, and the application exchange resource.Memory device obtains memory device respectively and sends and receive the required exchange resource amount of IO request.For example, memory device obtains to send IO respectively and asks concurrent number of times and receive IO to ask concurrent number of times, and will send IO and ask the required exchange resource amount of concurrent number of times as sending the required exchange resource amount of IO request, ask the required exchange resource amount of concurrent number of times as receiving the required exchange resource amount of IO request with receiving IO.Wherein, described transmission IO asks concurrent number of times in Preset Time, and memory device sends the number of times of IO request to remote equipment.It is in the Preset Time that described reception IO asks concurrent number of times, and memory device receives the number of times of the IO request that remote equipment sends.Preset Time in the embodiment of the invention can be set according to concrete performance, and the present invention does not do concrete restriction to this.
Step S202: memory device is according to the required exchange resource amount of described transmission IO request, distribute exchange resource from resource pool for the starter resource module, according to the required exchange resource amount of described reception IO request, distribute exchange resource from described resource pool for the object machine resource module.
Described memory device is provided with resource pool, starter resource module and object machine resource module.Wherein, described resource pool is deposited the total exchange resource of memory device, and provides exchange resource for described starter resource module and described object machine resource module.The exchange resource of described starter resource module and object machine resource module is separate.
Described memory device is according to the required exchange resource amount of described transmission IO request, distribute exchange resource from resource pool for the starter resource module, according to the required exchange resource amount of described reception IO request, distribute exchange resource from described resource pool for the object machine resource module.For example, memory device obtains to send and receive IO respectively and asks the required exchange resource amount of concurrent number of times, send IO from resource pool for the starter resource module distributes and ask the required exchange resource of concurrent number of times, ask the required exchange resource of concurrent number of times for the object machine resource module distributes reception IO.Wherein, the exchange resource of distributing to described starter resource module is separate with the exchange resource of distributing to described object machine resource module.The exchange resource that described starter resource module is deposited only is used for the INI business model, when memory device sends the IO request to remote equipment, for described memory device provides exchange resource.The exchange resource that described object machine resource module is deposited only is used for the TGT business model, when memory device receives the IO request of remote equipment transmission, for described memory device provides exchange resource.
Memory device is respectively described starter resource module and object machine resource module distribution exchange resource from resource pool after, if memory device sends the IO request to remote equipment, then to described starter resource module application exchange resource, if memory device receives the IO request that remote equipment sends, then preferentially to described object machine resource module application exchange resource.Memory device, can communicate with described remote equipment behind exchange resource to starter resource module or the application of object machine resource module.After INI or TGT business were finished, the exchange resource that memory device takies this business was discharged into corresponding resource module, i.e. starter resource module or object machine resource module.If less than exchange resource, then memory device is to resource pool application exchange resource to starter resource module or the application of object machine resource module for memory device.If memory device then communicate with described remote equipment, and after this business was finished, the exchange resource that this is professional discharged back resource pool to the resource pool application to exchange resource.If memory device less than exchange resource, then returns application less than the information of exchange resource to the resource pool application, at this moment, memory device can't communicate with described remote equipment, occurs unusual.
See also Fig. 3, Fig. 3 is the process flow diagram of another embodiment of the application's exchange resource management method.Described exchange resource management method may further comprise the steps:
Step S301: memory device asked concurrent number of times and receives IO to ask concurrent number of times to be added up to sending IO respectively in the default very first time.
Memory device asked concurrent number of times and receives IO to ask concurrent number of times to be added up to sending IO respectively in the default very first time, wherein, the concurrent number of times that described transmission IO asks concurrent number of times to be asked for the IO that sends to remote equipment, namely in the given time, memory device is to the number of times of the IO request of remote equipment transmission.It is the concurrent number of times that receives the IO request that remote equipment sends that described reception IO asks concurrent number of times, and namely in the Preset Time, memory device receives the number of times of the IO request that remote equipment sends.For example, the described default very first time is 10 seconds (S), and memory device obtains the 1st, the 2nd, the 3rd respectively ... the number of times of the IO request that the 10th second internal memory devices sends to remote equipment and receive the number of times of the IO request that remote equipment sends.In this example, the number of times of the IO request that the memory device per second sends to remote equipment is described transmissions IO asks concurrent number of times, and the memory device per second receives number of times that IO that remote equipment sends asks and is described reception IO and asks concurrent number of times.Certainly, memory device may not be added up interior all transmissions of the default very first time and receive IO and ask concurrent number of times, in other embodiments, memory device also can and receive IO to the transmission in the default very first time asks concurrent number of times to carry out sampling statistics, do not limit at this, Preset Time in the embodiment of the invention and the predetermined very first time can be set according to concrete performance, and the present invention does not do concrete restriction to this.
Step S302: memory device obtains an IO and asks concurrent value and the 2nd IO to ask concurrent value according to the statistics in described default very first time.
Memory device according in described default very first time to sending the statistics that IO asks concurrent number of times, obtain an IO and ask concurrent value, in the described default very first time, to receiving the statistics that IO asks concurrent number of times, obtain the 2nd IO and ask concurrent value.And memory device asks concurrent value and the 2nd IO to ask concurrent value to be kept in the internal memory of memory device an IO.Wherein, the transmission IO that a described IO asks concurrent value to obtain for statistics in described default very first time asks the maximal value in the concurrent number of times, the reception IO that described the 2nd IO asks concurrent value to obtain for statistics in described default very first time asks the maximal value in the concurrent number of times, perhaps, a described IO asks concurrent value for add up the mean value that the described transmission IO that obtains asks concurrent number of times in the described default very first time, and described the 2nd IO asks concurrent value for add up the mean value that the described reception IO that obtains asks concurrent number of times in the described default very first time.
In concrete the application, memory device can be according to statistics, ask the maximal value of concurrent number of times to ask concurrent value as a described IO to select in the described default very first time, to add up the transmission IO that obtains, to add up the reception IO that obtains in the described default very first time asks the maximal value of concurrent number of times to ask concurrent value as the 2nd IO, perhaps select in the described default very first time, to add up the transmission IO that obtains and ask the mean value of concurrent number of times to ask concurrent value as a described IO, will in the described default very first time, add up the reception O that obtains and ask the mean value of concurrent number of times to ask concurrent value as the 2nd IO.If the service concurrence amount of memory device operation is relatively more unstable, in the default very first time, send or receive IO and ask to differ bigger between concurrent number of times, ask concurrent number of times required for guaranteeing the exchange resource satisfied transmission as much as possible that memory device distributes or receiving IO, memory device will be added up the transmission IO that obtains in the described default very first time asks the maximal value in the concurrent number of times to ask concurrent value as an IO, asks the maximal value in the concurrent number of times to ask concurrent value as the 2nd IO with receiving IO.If the service concurrence amount of memory device operation is more stable, sending or receive IO in the default very first time asks to change between concurrent number of times little, then memory device can ask the mean value of concurrent number of times to ask concurrent value as an IO with sending IO in the default very first time, or reception IO asks the mean value of concurrent number of times to ask concurrent value as the 2nd IO.
Step S303: memory device obtains a N IO asks concurrent value and N the 2nd IO to ask concurrent value, ask concurrent value to obtain an IO according to the N that obtains a described IO and ask concurrent mean value, ask concurrent value to obtain the 2nd IO according to the described N that obtains the 2nd IO and ask concurrent mean value, ask the required exchange resource amount of concurrent mean value as sending the required exchange resource amount of IO request the one IO, ask the required exchange resource amount of concurrent mean value as receiving the required exchange resource amount of IO request the 2nd IO.Wherein, N is natural number, and the concrete value of N can determine that the embodiment of the invention is not done concrete restriction to this according to concrete actual conditions.
Memory device repeats above-mentioned steps S301 and step S302, ask concurrent value and N the 2nd IO to ask concurrent value to obtain at a N IO, and ask concurrent value according to a N IO, calculate acquisition the one IO and ask concurrent mean value, ask concurrent value according to N the 2nd IO, calculate acquisition the 2nd IO and ask concurrent mean value.Wherein, it is the mean value that a described N IO asks concurrent value that a described IO asks concurrent mean value, and it is the mean value that described N the 2nd IO asks concurrent value that the 2nd IO asks concurrent mean value.
Memory device obtains first, after the 2nd IO asks concurrent mean value, ask the required exchange resource amount of concurrent mean value as the required exchange resource amount of described transmission IO request a described IO, ask the required exchange resource amount of concurrent mean value as the required exchange resource amount of described reception IO request described the 2nd IO, so that memory device is asked the required exchange resource amount of concurrent mean value according to an IO, distribute exchange resource from resource pool for the starter resource module, ask the required exchange resource amount of concurrent mean value according to the 2nd IO, distribute exchange resource from resource pool for the object machine resource module.
Describe for example, memory device in 10 seconds respectively to the 2nd, 4,6,8,10 seconds transmission IO asks concurrent number of times and receives IO to ask concurrent number of times to be added up, obtaining statistics is: the 2nd, 4,6,8,10 seconds transmission IO asks concurrent number of times to be respectively 210,180,260,190,350, the 2nd, 4,6,8,10 seconds reception IO asks concurrent number of times to be respectively 100,150,260,80,170, ask the maximal value of concurrent number of times to ask concurrent value as an IO to send IO, ask the maximal value of concurrent number of times to ask concurrent value as the 2nd IO to receive IO.Be that first, second IO asks concurrent value to be respectively 350,260.Memory device continued at next 10 seconds to ask concurrent number of times and receive IO to ask concurrent number of times to carry out above-mentioned statistics to sending IO, ask concurrent value with first, second IO that obtains in these 10 seconds, ask concurrent value up to obtaining 6 first, second IO in 10 seconds.Wherein, described 6 IO ask concurrent value to be followed successively by 350,350,370,360,320, memory device obtains an IO, and to ask concurrent mean value be 350, and namely an IO asks the required exchange resource amount of concurrent mean value for sending the required exchange resource amounts of IO request 350 times.Described 6 the 2nd IO ask concurrent value to be followed successively by 260,230,270,300,280, memory device obtains a described IO, and to ask concurrent mean value be 270, and namely the 2nd IO asks the required exchange resource amount of concurrent mean value for receiving the required exchange resource amounts of IO request 270 times.Memory device will send the required exchange resource amount of 350 IO requests and send the required exchange resource amount of IO request as memory device, will receive the required exchange resource amount of 270 IO requests as receiving the required exchange resource amount of IO request.
Step S304: memory device is asked the required exchange resource of concurrent mean value from described resource pool for the starter resource module distributes an IO, asks the required exchange resource of concurrent mean value from described resource pool for the object machine resource module distributes the 2nd IO.
In the present embodiment, memory device obtains a described IO ask concurrent mean value and the 2nd IO to ask concurrent mean value after, from described resource pool, equal the exchange resource that an IO asks the required exchange resource amount of concurrent mean value for starter resource module quantity allotted, from described resource pool, equal the exchange resource that the 2nd IO asks the required exchange resource amount of concurrent mean value for object machine resource module quantity allotted.
Certainly, memory device is not limited to quantity is distributed to the starter resource module with the exchange resource that a described IO asks the required exchange resource amount of concurrent mean value to equate, will distribute to the object machine resource module with the exchange resource that described the 2nd IO asks the required exchange resource amount of concurrent mean value to equate.In other embodiments, as memory device can according to as described in an IO ask the ratio of the required exchange resource amount of concurrent mean value, the exchange resource of described resource pool is distributed to the starter resource module respectively, ask the ratio of the required exchange resource amount of concurrent mean value according to the 2nd IO, the exchange resource of described resource pool is distributed to the object machine resource module respectively, perhaps memory device is respectively in described first of acquisition, the 2nd IO asks on the required exchange resource basis of concurrent mean value, increase some exchange resources again, obtain enough exchange resources to guarantee starter resource module and object machine resource module.
In the present embodiment, memory device is by obtaining a plurality of first, the 2nd IO asks concurrent value, obtain more stable first, the 2nd IO asks concurrent mean value, and ask the required exchange resource amount of concurrent mean value according to an IO, from resource pool, distribute exchange resource for the starter resource module, ask the required exchange resource amount of concurrent mean value according to the 2nd IO, from resource pool, for the object machine resource module distributes exchange resource, reduced the starter resource module, the error of the exchange resource amount that the object machine resource module is assigned to and the exchange resource amount of the corresponding professional actual needs of memory device.
Need to prove that in addition step S303 is optional step.In another embodiment, after memory device execution in step S301, step S302 obtain first, second IO and ask concurrent value, ask the required exchange resource amount of concurrent value as the required exchange resource amount of described transmission IO request the one IO, ask concurrent value as the required exchange resource amount of described reception IO request the 2nd IO.Memory device execution in step S304, to ask the required exchange resource amount of concurrent value according to an IO, from described resource pool, distribute exchange resource for the starter resource module, ask the required exchange resource amount of concurrent value according to the 2nd IO, from described resource pool, distribute exchange resource for the object machine resource module.
Step S305: first in second time that memory device obtains respectively to preset overflows exchange resource amount and second and overflows the exchange resource amount.
When memory device sends the IO request to remote equipment, preferentially to starter resource module application exchange resource.If less than exchange resource, then memory device is to resource pool application exchange resource to the application of starter resource module for memory device.Described to the application of starter resource module less than the exchange resource amount be the exchange resource amount that the starter resource module lacks, namely first overflows the exchange resource amount.When memory device receives the IO request that described remote equipment sends, preferentially to described object machine resource module application exchange resource.If less than exchange resource, then memory device is to resource pool application exchange resource to the application of object machine resource module for memory device.Described to the application of object machine resource module less than the exchange resource amount be the exchange resource amount that the object machine resource module lacks, namely second overflows the exchange resource amount.Memory device obtains first overflowing exchange resource amount and second and overflow the exchange resource amount in the second default time.
Step S306: memory device overflows the exchange resource amount according to described first, again be that described starter resource module distributes exchange resource from described resource pool, overflowing the exchange resource amount according to described second, is that described object machine resource module distributes exchange resource from described resource pool again.
Memory device obtains for first in the second default time and overflows after exchange resource amount and second overflows the exchange resource amount, again be that starter resource module and object machine resource module distribute exchange resource from resource pool, receive the required exchange resource of IO request so that described starter resource module provides to satisfy to send the required exchange resource of IO request and described object machine resource module is provided to satisfy.Wherein, the exchange resource amount that memory device distributes for the starter resource module again be the exchange resource amount and described first of distributing to the starter resource module last time overflow the exchange resource amount and, memory device again for the exchange resource amount of object machine resource module distribution be the exchange resource amount and described second of distributing to described object machine resource module last time overflow the exchange resource amount with.
If the exchange resource amount in the resource pool less than memory device need redistribute to starter resource module and object machine resource module exchange resource amount and, then need redistribute ratio to starter resource module and object machine resource module exchange resource amount according to current memory device, all exchange resources of resource pool are redistributed to starter resource module and object machine resource module.
Repeated execution of steps S305, step S306, with every the described second default time, overflow exchange resource amount and described second according to described first and overflow the exchange resource amount, again be that starter resource module and object machine resource module distribute exchange resource from described resource pool, after from described resource pool being starter resource module and object machine resource module distribution exchange resource again, described resource pool does not have remaining exchange resource, at this moment, memory device is that starter resource module and object machine resource module distribute exchange resource no longer again.
Need to prove, the exchange resource amount and first that memory device distributes the exchange resource amount to be not limited to sub-distribution on the described starter resource module for the starter resource module again overflow the exchange resource amount and, the exchange resource amount and second that memory device distributes the exchange resource amount to be not limited to described object machine resource module distribution for the object machine resource module again overflow the exchange resource amount with.
In the present embodiment, described first, second default time and N are by the memory apparatus system default settings.But in other embodiments, described first, second default time and N also can be preestablished by the user, do not limit at this, and wherein N is natural number.
Further, carrying out exchange resource when redistributing, memory device also may not overflow the exchange resource amount with first, second, is that starter resource module and object machine resource module distribute exchange resource again from resource pool.In other embodiments, memory device can be at execution in step S304, according to sending the required exchange resource amount of IO request, distribute exchange resource from resource pool for the starter resource module, according to receiving the required exchange resource amount of IO request, after distributing exchange resource for the object machine resource module from resource pool, not execution in step S305, S306.Memory device is every default the 3rd time, re-execute step S301 to step S304, to ask required exchange resource amount according to the transmission IO that regains, again distribute exchange resource for the starter resource module from resource pool, according to the required exchange resource amount of reception IO request that regains, resource pool distributes exchange resource for the object machine resource module again.Wherein default the 3rd time is greater than the default very first time.
In the present embodiment, memory device arranges separate starter resource module and object machine resource module, simultaneously, each default second time of memory device is redistributed the exchange resource amount of starter resource module and object machine resource module, make the exchange resource amount of starter resource module and object machine resource module to ask required exchange resource amount corresponding with the actual transmission of current memory device and reception IO as far as possible, the exchange resource that has guaranteed resource module can satisfy memory device corresponding service demand, has improved the performance of memory device service operation.
Specifically, in conjunction with following table one, two, memory device existing resource way to manage and the application's resource management mode are compared, so that technique effect of the present invention to be described.
Please consult following table one earlier, memory device operation INI business model and TGT business model, all be to resource pool application exchange resource, because the resource management of memory device has mutual exclusion lock character, must wait for namely that a last exchange resource application is finished just can carry out the application of next exchange resource.So when memory device moves two kinds of business models simultaneously, exist the exchange resource competition.At this moment, when a kind of business model of memory device occurs when unusual, then can influence the runnability of another kind of business model.For example, total exchange resource amount of resource pool is 2048.The INI business model occurs unusual, and constantly to resource pool application exchange resource, up to all exchange resources that take resource pool, namely the stock number of INI business model application is 2048.At this moment, the TGT business model less than any exchange resource, makes the TGT business model normally to move to the resource pool application, so influenced the TGT business model.In like manner, the TGT business model occurs unusual, taken all or most of exchange resource of resource pool, make the INI business apply for fully less than exchange resource or the exchange resource that can apply for seldom, and then the INI business model can't normally have been moved or the operation progress is affected.
See also following table two, the present invention is according to the required exchange resource amount of described transmission IO request, distribute exchange resource from resource pool for the starter resource module, according to the required exchange resource amount of described reception IO request, distribute exchange resource from described resource pool for the object machine resource module, and provide the INI business model required exchange resource by the starter resource module, the object machine resource module provides TGT the exchange resource of professional required formula, make that the exchange resource of INI and two kinds of business models of TGT is separate, therefore do not have the exchange resource competition of INI and two kinds of business of TGT.In addition, even wherein a kind of business model occurs also can not influencing another kind of business model unusually.For example, total exchange resource amount of resource pool is 2048, and the exchange resource amount of distributing to the starter resource module is 1024, and the exchange resource amount of distributing to the object machine resource module is 512.The INI business model occurs unusual, behind the exchange resource that exhausts the starter resource module, continues to resource pool application exchange resource, also exhausts up to the remaining exchange resource of resource pool, and at this moment, the exchange resource amount of INI business model application is 1536.Because starter resource module and object machine resource module are separate, therefore, the INI business model can't be to object machine resource module application exchange resource, and the object machine resource module is still being deposited 512 exchange resource for the application of TGT business model.In like manner, the TGT business model unusually can not have influence on the INI business model yet.

Fig. 4 is the structural representation of the application's exchange resource management devices one embodiment.See also Fig. 4, described exchange resource management devices comprises starter resource module 410, object machine resource module 420, acquisition module 430 and first distribution module 440.
Object machine resource module 420 is used for providing described reception IO request required exchange resource, the IO request that described reception IO request sends for receiving remote equipment.
Acquisition module 430 is used for obtaining respectively transmission and receives the required exchange resource amount of IO request, and described transmission and the required exchange resource amount of described reception IO request are sent to first distribution module 440.Memory device has with a mouthful attribute, can move INI and TGT business model.Memory device sends the IO request to remote equipment when operation INI business model, and the application exchange resource, when operation TGT business model, receives the IO request that remote equipment sends, and the application exchange resource.Acquisition module 430 obtains memory device respectively and sends and receive the required exchange resource amount of IO request.For example, acquisition module 430 obtains memory device transmission IO respectively asks concurrent number of times and receives IO to ask concurrent number of times, and will send IO and ask the required exchange resource amount of concurrent number of times as sending the required exchange resource amount of IO request, ask the required exchange resource amount of concurrent number of times as receiving the required exchange resource amount of IO request with receiving IO.Wherein, described transmission IO asks concurrent number of times in the given time, and memory device sends the number of times of IO request to remote equipment.It is in the schedule time that described reception IO asks concurrent number of times, and memory device receives the number of times of the IO request that remote equipment sends.Preset Time in the embodiment of the invention can be set according to concrete performance, and the present invention does not do concrete restriction to this.
Described memory device is provided with resource pool, and described resource pool is deposited the total exchange resource of memory device, and provides exchange resource for described starter resource module and described object machine resource module.First distribution module 440 sends and receives the required exchange resource amount of IO request respectively according to memory device, be respectively starter resource module 410 and object machine resource module 420 distribution exchange resources from resource pool.For example, first distribution module 440 is asked the required exchange resource amount of concurrent number of times according to obtaining memory device transmission IO, be that starter resource module 410 distributes and sends IO and ask the required exchange resource of concurrent number of times from resource pool, first distribution module 440 is asked the required exchange resource amount of concurrent number of times according to obtaining memory device reception IO, is that object machine resource module 420 distributes reception IO to ask the required exchange resource of concurrent number of times from resource pool.
Fig. 5 is the structural representation of another embodiment of the application's exchange resource management devices.See also Fig. 5, described exchange resource management devices comprises starter resource module 510, object machine resource module 520, acquisition module 530, first distribution module 540 and second distribution module 550.Wherein, acquisition module 530 comprises first statistic unit 531 and first computing unit 532.Starter resource module 510 in the present embodiment, object machine resource module 520 are identical with starter resource module, the object machine resource module of a last embodiment, see also the related text explanation, do not repeat them here.
First statistic unit 531 is used for asking concurrent number of times and receive IO to ask concurrent number of times to be added up to sending IO respectively in the default very first time, and statistics is sent to first computing unit 532.
Particularly, first statistic unit 531 asked concurrent number of times and receives IO to ask concurrent number of times to be added up to sending IO respectively in the default very first time, wherein, it is that memory device is to the concurrent number of times of the IO request of remote equipment transmission that described transmission IO asks concurrent number of times, namely in the given time, memory device is to the number of times of the IO request of remote equipment transmission.It is the concurrent number of times that memory device receives the IO request that remote equipment sends that described reception IO asks concurrent number of times, and namely in the given time, memory device receives the number of times of the IO request that remote equipment sends.For example, the described default very first time is 10 seconds (S), and first statistic unit 531 obtains the 1st, the 2nd, the 3rd respectively ... sending IO on the 10th second asks concurrent number of times and receives IO to ask concurrent number of times.In this example, the number of times of the IO request that the memory device per second sends to remote equipment is described transmissions IO asks concurrent number of times, and the memory device per second receives number of times that IO that remote equipment sends asks and is described reception IO and asks concurrent number of times.Certainly, first statistic unit may not be added up interior all transmissions of the default very first time and receive IO and ask concurrent number of times, in other embodiments, first statistic unit also can and receive IO to the transmission in the default very first time asks concurrent number of times to carry out sampling statistics, does not limit at this.
First computing unit 532 according to memory device in described default very first time to sending the statistics that IO asks concurrent number of times, obtain an IO and ask concurrent value, in the described default very first time, to receiving the statistics that IO asks concurrent number of times, obtain the 2nd IO and ask concurrent value.First computing unit 532 asks the required exchange resource amount of concurrent value as sending the required exchange resource amount of IO request the one IO, ask the required exchange resource amount of concurrent value to ask required exchange resource amount as receiving IO the 2nd IO, and ask required respectively exchange resource amount to send to first distribution module 540 described transmission and described reception IO.Wherein, the transmission IO that a described IO asks concurrent value to obtain for statistics in described default very first time asks the maximal value in the concurrent number of times, the reception IO that described the 2nd IO asks concurrent value to obtain for statistics in described default very first time asks the maximal value in the concurrent number of times, perhaps, a described IO asks concurrent value for add up the mean value that the described transmission IO that obtains asks concurrent number of times in the described default very first time, and described the 2nd IO asks concurrent value for add up the mean value that the described reception IO that obtains asks concurrent number of times in the described default very first time.
In concrete the application, first computing unit 532 can be according to statistics, ask the maximal value of concurrent number of times to ask concurrent value as described first and second IO respectively to select in the described default very first time, to add up the transmission that obtains and to receive IO, ask the mean value of concurrent number of times to ask concurrent value as described first and second IO respectively to select in the described default very first time, to add up the transmission that obtains and to receive IO.If the service concurrence amount of memory device operation is relatively more unstable, in the default very first time, send or receive IO and ask to differ bigger between concurrent number of times, ask concurrent number of times required for guaranteeing the exchange resource satisfied transmission as much as possible that memory device distributes or receiving IO, first computing unit 532 will be added up the transmission IO that obtains in the described default very first time asks the maximal value in the concurrent number of times to ask concurrent value as an IO, will add up the reception IO that obtains in the described default very first time and ask the maximal value in the concurrent number of times to ask concurrent value as the 2nd IO.If the service concurrence amount of memory device operation is more stable, sending or receive IO in the default very first time asks to change between concurrent number of times little, then first computing unit 532 can ask the mean value of concurrent number of times to ask concurrent value as an IO with sending IO in the default very first time, asks the mean value of concurrent number of times to ask concurrent value as the 2nd IO with receiving IO in the very first time of establishing.
In the present embodiment, first distribution module 540 is asked the required exchange resource of concurrent value for starter resource module 510 distributes an IO from described resource pool, asks the required exchange resource of concurrent value for object machine resource module 520 distributes the 2nd IO.
Certainly, first distribution module is not limited to asking the equal corresponding starter resource module of distributing to of exchange resource of concurrent value quantity with a described IO exchange resource correspondence that described the 2nd IO asks concurrent value quantity to equate be distributed to the object machine resource module.In other embodiments, first distribution module can ask concurrent value and described the 2nd IO to ask the ratio of concurrent value according to a described IO, the exchange resource of described resource pool is distributed to starter resource module and object machine resource module respectively, perhaps first distribution module is asked on the required exchange resource basis of concurrent mean value at described first, second IO that obtains respectively, increase some exchange resources again, obtain enough exchange resources to guarantee starter resource module and object machine resource module.
When memory device sends the IO request to remote equipment, preferentially to starter resource module 510 application exchange resources.If less than exchange resource, then memory device is to resource pool application exchange resource to 510 applications of starter resource module for memory device.Described to starter resource module 510 application less than the exchange resource amount be the exchange resource amount that starter resource module 510 lacks, namely first overflows the exchange resource amount.When memory device receives the IO request that described remote equipment sends, preferentially to described object machine resource module 520 application exchange resources.If less than exchange resource, then memory device is to resource pool application exchange resource to 520 applications of object machine resource module for memory device.Described to object machine resource module 520 application less than the exchange resource amount be the exchange resource amount that object machine resource module 520 lacks, namely second overflows the exchange resource amount.
If the exchange resource amount of resource pool less than second distribution module 550 need redistribute to the exchange resource amount of starter resource module 510 and object machine resource module 520 and, then second distribution module 550 is redistributed ratio to the exchange resource amount of starter resource module 510 and object machine resource module 520 according to current needs, and all exchange resources of resource pool are redistributed respectively to starter resource module 510 and object machine resource module 520.
Every the described second default time, second distribution module 550 is overflowed exchange resource amount and described second according to described first and is overflowed the exchange resource amount, again be respectively starter resource module 510 and object machine resource module 520 distribution exchange resources from described resource pool, after from described resource pool being starter resource module 510 and object machine resource module 520 distribution exchange resources again, described resource pool does not have remaining exchange resource.At this moment, second distribution module 550 is that starter resource module 510 and object machine resource module 520 distribute exchange resource no longer again.
Need to prove, the exchange resource amount that second distribution module is distributed for the starter resource module again be not limited to the exchange resource amount and first of distributing to the starter resource module last time overflow the exchange resource amount and, second distribution module again for the exchange resource amount of object machine resource module distribution be not limited to the exchange resource amount and second of distributing to the object machine resource module last time overflow the exchange resource amount with.In other embodiments, second distribution module can according to described two and ratio, the exchange resource of described resource pool is distributed to starter resource module and object machine resource module respectively, perhaps second distribution module is asked on the required exchange resource basis of concurrent mean value at described first, second IO that obtains respectively, increase certain data volume exchange resource again, obtain enough exchange resources to guarantee starter resource module and object machine resource module.
In the present embodiment, described first, second default time and N are the default value of exchange resource management devices.But in other application implementation modes, described first, second default time and N also can be the predefined value of user, do not limit at this, and wherein N is natural number.
Further, carrying out exchange resource when redistributing, the exchange resource management devices also may not overflow the exchange resource amount according to first, second, is that starter resource module and object machine resource module distribute exchange resource again from resource pool.In other embodiments, the exchange resource management devices can not comprise second distribution module, the acquisition module of exchange resource management devices also is used for every default the 3rd time, transmission IO according to memory device asks concurrent number of times and receives IO to ask concurrent number of times respectively, obtain first and second IO and ask concurrent value, first distribution module is asked the required exchange resource amount of concurrent value according to an IO, again distribute exchange resource for the starter resource module from resource pool, ask the required exchange resource amount of concurrent value according to the 2nd IO, distribute exchange resource for the object machine resource module again from resource pool.Wherein, default the 3rd time is greater than the default very first time.
Further, in other embodiments, exchange resource management devices of the present invention can also comprise the application module, described application module is used for when memory device sends the IO request to remote equipment, to described starter resource module application exchange resource, when memory device receives the IO request that remote equipment sends, preferentially to described object machine resource module application exchange resource.To starter resource module or the application of object machine resource module during less than exchange resource, to resource pool application exchange resource.
In the present embodiment, the exchange resource management devices arranges separate starter resource module and object machine resource module, and the exchange resource of starter resource module and object machine resource module is separate, simultaneously, the exchange resource management devices carries out again distribution every default second time to the exchange resource amount of starter resource module and object machine resource module, make the exchange resource amount of starter resource module and object machine resource module to ask required exchange resource amount with the actual transmission of current memory device and reception IO as far as possible, the exchange resource that has guaranteed resource module can satisfy memory device corresponding service demand, has improved the performance of memory device service operation.
Optimally, see also Fig. 6, Fig. 6 is the exchange resource management devices of the present invention structural representation of an embodiment again.The resource management apparatus of the resource management apparatus in the present embodiment and a last embodiment is basic identical, and its difference is that acquisition module 630 comprises second statistic unit 631 and second computing unit 632.
Second statistic unit 631 is used for asking concurrent number of times and receive IO to ask concurrent number of times to be added up to sending IO respectively in N the default very first time, and the statistics in N the default very first time is sent to second computing unit 632.Wherein, the mode that second statistic unit 631 is added up is identical with the statistical of a last embodiment first statistic unit, does not give unnecessary details at this.
Second computing unit 632 is used for respectively according to the statistics in N the default very first time, obtaining a N IO asks concurrent value and N the 2nd IO to ask concurrent value, ask concurrent value to obtain an IO according to the described N that obtains a described IO and ask concurrent mean value, ask concurrent value to obtain the 2nd IO according to the described N that obtains the 2nd IO and ask concurrent mean value, ask the required exchange resource amount of concurrent mean value as the required exchange resource amount of described transmission IO request a described IO, ask concurrent mean value as the required exchange resource amount of described reception IO request described the 2nd IO, and ask required respectively exchange resource amount to send to first distribution module 640 described transmission and described reception IO.Wherein, first, second IO in the present embodiment asks concurrent value to ask concurrent value identical with first, second IO in the last embodiment, so be not repeated in this description.It is the mean value that a described N IO asks concurrent value that a described IO asks concurrent mean value, and it is the mean value that described N the 2nd IO asks concurrent value that described the 2nd IO asks concurrent mean value.
First distribution module 640 is asked concurrent mean value according to a described IO, exchange resource in the described resource pool is distributed to starter resource module 610, ask concurrent mean value according to described the 2nd IO, the exchange resource in the described resource pool is distributed to object machine resource module 620.
Describe for example, second statistic unit 631 asked concurrent number of times and received IO to ask concurrent number of times to be added up to sending IO respectively in 10 seconds, obtaining statistics is: the transmission IO at the 2nd, 4,6,8,10 second asks concurrent number of times to be respectively 210,180,260,190,350, and the reception IO at the 2nd, 4,6,8,10 second asks concurrent number of times to be respectively 100,150,260,80,170.First computing unit 532 asks the maximal value of concurrent number of times to ask concurrent value as first, second IO to send and to receive IO respectively, and namely first and second IO ask concurrent value to be respectively 350,260.Second statistic unit 631 continued at next 10 seconds to ask concurrent number of times and receive IO to ask concurrent number of times to carry out above-mentioned statistics to sending IO, so that first and second IO that second computing unit 632 obtains respectively in these 10 seconds ask concurrent value, ask concurrent value up to obtaining 6 first and second IO in 10 seconds, wherein, described 6 IO ask concurrent value to be followed successively by 350,350,370,360,320, it is 350 that described 6 IO of second computing unit, 632 acquisitions ask the mean value of concurrent value, and namely an IO asks the required exchange resource amount of concurrent mean value for sending the required exchange resource amounts of IO request 350 times.Described 6 the 2nd IO ask concurrent value to be followed successively by 260,230,270,300,280, it is 270 that described 6 the 2nd IO of second computing unit, 63 acquisitions ask the mean value of concurrent value, and namely the 2nd IO asks the required exchange resource amount of concurrent mean value for receiving the required exchange resource amounts of IO request 270 times.First distribution module 640 is distributed to starter resource module 610 with sending 350 required exchange resource amounts of IO request in the resource pool, distributes to object machine resource module 620 with receiving 270 required exchange resource amounts of IO request in the resource pool.
