Have a plurality of collocation strategies in the database 130.In the present embodiment, collocation strategy can comprise that security of system (security) is preferential, system effectiveness (performance) is preferential, download (download) is preferential, it is preferential preferential with last download to upload (upload).These collocation strategies complete in server system 100 and default in the database 130 and can be manufacturer, or server system 100 can provide figure user interface (graphic user interface, GUI), set up the self-defining collocation strategy of user in addition for the user.That is to say that the user sets up the collocation strategy of different degree of priority according to its demand.
For instance, the user can be preferential with system effectiveness, download preferential with upload preferential degree be made as " height ", " in " with " low " so that server system 100 can be set the configuration mode of virtual machine accordingly.In addition, the self-defining collocation strategy of user also can comprise " system effectiveness degree of priority, upload degree of priority, download degree of priority " simultaneously.For instance, when collocation strategy is " high, high, height ", representing the system effectiveness degree of priority, uploading degree of priority all is " height " with downloading degree of priority, also be that the virtual machine in virtual the gathering together needs a large amount of operational datas, and virtual gathering together need externally be carried out data communication in a large number.
When collocation strategy is " in, in, in ", expression system effectiveness degree of priority, upload degree of priority with download degree of priority all be " in ", also be that the virtual interior virtual machine of gathering together needs suitable operational data, and virtual gathering together need suitably externally be carried out communication.When collocation strategy was " low, low, low ", representing the system effectiveness degree of priority, uploading degree of priority all was " low " with downloading degree of priority, represent that the virtual machine in virtual the gathering together is seldom measured operational data, and virtual gathering together is seldom externally carried out communication.
Control module 140 couples exchanger unit 120 (for example interchanger 121_1) and database 130.In the present embodiment, after server system 100 configurations are finished, control module 140 for example receives configuration-direct (for example look its demand by the user and pass through the generation of figure user interface), and in collocation strategy, obtain one as selecting collocation strategy according to configuration-direct, again according to aforesaid selection collocation strategy, with at least one virtual gathering together (virtual cluster, VC) a plurality of virtual machines (virtual machine, VM) be dispensed to corresponding node 110_1~110_N, but make server system 100 normal operations.
Then, control module 140 can be collected the relevant information of aforementioned virtual virtual machine of gathering together.Wherein, the relevant information of virtual machine comprises the traffic between the virtual machine, the data volume of virtual machine transmission and the data volume that virtual machine receives.Afterwards, control module 140 can be analyzed the relevant information of virtual machine, to obtain corresponding this virtual virtual characteristic of gathering together of gathering together, again according to the virtual characteristic of gathering together, by the collocation strategy that makes new advances of correspondence in a plurality of collocation strategies in the database 130.Then, control module 140 is redistributed virtual machine and be dispensed to corresponding node 110_1~110_N again according to new collocation strategy.
In one embodiment, after obtaining new collocation strategy, control module 140 also can detect an activation signal.When having detected enable signal, 140 new collocation strategies of foundation of control module reassign to corresponding node with virtual machine.Otherwise, when detecting no enable signal, 140 of control modules can not redistributed virtual machine, and the related data of collecting aforementioned virtual virtual machine of gathering together constantly, to obtain a corresponding new collocation strategy again, till having detected enable signal.
Router one 50 couples exchanger unit 120, be sent to client (client) 190 in order to the data with each node by network (internet) 180, perhaps will receive the data that client 190 transmits by network 180, and its data that receive will be sent to each node by exchanger unit 120.And the router one 50 of present embodiment can comprise output router (outgoing router) and input router (ingoing router).Wherein, the output router can be sent to client 190 by network 180 with the data of each node, and input router can receive the data that client 190 transmits by network 180, and the data that input router receives can be sent to each node via exchanger unit 120 again.Thus, control module 140 can be according to the running of server system 100 the dynamic position of mobile virtual machine, make server system 100 be adjusted to suitable operating state.In addition, control module 140 also visual user's demand determines whether to adjust the operating state of server system 100, and then increases the convenience that uses.
Next, the operation of server system 100 of the present invention will be further specified.
At first, after server system 100 configurations were finished, the user set up aforesaid virtual gathering together by figure user interface, and this virtual gathering together has a plurality of virtual machines.Then, the user produces configuration-direct (being the allocation plan of virtual machine) by figure user interface again, and is received by control module 140.Afterwards, control module 140 can be obtained corresponding collocation strategy according to configuration-direct in database 130, with the configuration of the virtual machine be scheduled to, so that server system 100 normal operations.
When collocation strategy is system effectiveness when preferential, expression need be concentrated the node that is dispensed to part with virtual machine.For instance, control module 140 can preferentially be disposed at all virtual machines same node (for example node 110_1).In another embodiment, if the quantity of the virtual machine that node 110_1 can dispose has reached the upper limit, then further remaining virtual machine is disposed at another node 110_2 in the same area 160_1.Then, if the quantity of the virtual machine that all the node 110_1~110_3 in the regional 160_1 can dispose has all reached the upper limit, then further remaining virtual machine is disposed at a node (110_4 for example of another the regional 160_2 in the same rack 170_1, do not illustrate), by that analogy, finish up to all virtual machine configurations.That is to say, be system effectiveness when preferential when selecting collocation strategy, then all virtual machines all is disposed at same node, so that server system 100 can be finished a large amount of arithmetic operations as far as possible.
When collocation strategy is the system effectiveness of degree " height " when preferential, expression need be disposed at virtual machine same rack, the same area and same node in regular turn.Therefore, control module 140 for example is disposed at all virtual machines rack 170_1, regional 160_1 and node 110_1 as far as possible in regular turn.When select collocation strategy be degree " in " system effectiveness when preferential, expression need be disposed at virtual machine same rack, the same area and different nodes in regular turn.Therefore, control module 140 for example is disposed at all virtual machines rack 170_1, regional 160_1~160_2 and node 110_1~110_6 in regular turn.
Be the system effectiveness of degree " low " when preferential when selecting collocation strategy, expression need be disposed at virtual machine same rack, zones of different and different nodes in regular turn.Therefore, control module 140 for example is disposed at virtual machine rack 170_1, regional 160_1~160_M and node 110_1~110_N in regular turn.
When collocation strategy is preferential for downloading preferentially and uploading, then need virtual machine is disposed at the node that couples apart from router one 50 nearer interchangers.Therefore, control module 140 virtual machines are disposed at the node that couples apart from router one 50 nearer interchangers (for example interchanger 121_1).Wherein, when control module 140 is disposed at the node that couples apart from the nearer interchanger 121_1 of output router with virtual machine, server system 100 can utilize virtual machine via network 180 data to be sent out in a large number, also is that client 190 can be downloaded lot of data to server system 100 by network 180.
In addition, when control module 140 is disposed at the node that the interchanger 121_1 nearer apart from input router couple with virtual machine, server system 100 can also be that client 190 can upload the data to server system 100 by network 180 in a large number via obtaining demand for services (service requests) or data (data) in the network 180.In addition, when control module 140 is disposed at virtual machine the node that the interchanger 121_1 nearer apart from input router and output router couples simultaneously, so that server system 100 can utilize virtual machine data to be sent out (namely being sent to client 190) via network 180 in a large number, and simultaneously in a large number via obtaining demand for services or data in the network 180.
When select collocation strategy be the download of degree " height " preferential with upload when preferential, control module 140 can be disposed at virtual machine the node that couples apart from the nearer interchanger 121_1 of router one 50 (output router, input router and output router and input router).Thus, server system 100 can transmit or receive data in a large number.
When select collocation strategy be degree " in " download preferential with upload when preferential, control module 140 can be disposed at virtual machine the node that couples apart between the nearer interchanger 121_1 of router one 50 (output router, input router and output router and input router) and the interchanger 121_N.Thus, the transmission that server system 100 can be moderate or reception data.When select collocation strategy be the download of degree " low " preferential with upload when preferential, control module 140 can be disposed at virtual machine the node that couples apart between router one 50 (output router, input router and output router and input router) the interchanger 121_N far away.Thus, the transmission that server system 100 can be in a small amount or receive data.
In addition, when select collocation strategy be respectively " high, high, height ", the time, control module 140 can be disposed at same rack, the same area and same node with virtual machine, and virtual machine can be disposed at the node that couples apart from router one 50 nearer interchangers (for example 121_1).When to select collocation strategy be " in, in, in ", control module 140 can be disposed at same rack, the same area and different nodes with virtual machine, and virtual machine can be disposed at the node that couples apart between the nearer interchanger (for example 121_1) of router one 50 and the interchanger (for example 121_N).
When selecting collocation strategy to be " low, low, low ", control module 140 can be disposed at same rack, zones of different and different nodes with virtual machine, and virtual machine can be disposed at the node that couples apart between router one 50 interchanger (for example 121_N) far away.
Then, in the related data that control module 140 can be collected aforementioned virtual virtual machine of gathering together, just collect the data volume of traffic between the virtual machine, virtual machine transmission and the data volume that virtual machine receives.Wherein, the traffic between the virtual machine is expressed as the operation efficiency of the data of server system 100; The data volume that virtual machine transmits is represented to transmit data to the data volume of client 190 via router one 50 by network 180; The data volume that virtual machine receives represents to receive by network 180 via router one 50 data volume of the data that clients transmit.
Afterwards, control module 140 can be analyzed the data volume of traffic, virtual machine transmission between the virtual machine and the data volume that virtual machine receives, also namely compare with a preset value respectively, with distinguish " data volume that the data volume that traffic between the virtual machine, virtual machine transmit and virtual machine receive " be " height ", " in " with " low ", also be the virtual virtual characteristic of gathering together of gathering together of correspondence.
Then, control module 140 can be according to the virtual characteristic of gathering together, the correspondence collocation strategy that makes new advances in a plurality of collocation strategies in database 130.For instance, when the virtual characteristic of gathering together is " high, high, height ", represent that the virtual machine in virtual the gathering together needs a large amount of operational datas, and virtual gathering together need externally be carried out data communication in a large number, and correspondence goes out the system effectiveness degree of priority so control module 140 is understood accordingly, upload degree of priority all is the new collocation strategy of " height " with downloading degree of priority.Afterwards, control module 140 is the new collocation strategy of " high, high, height " in regular turn, and virtual machine is reassigned to corresponding node 110_1~110_N.
