Embodiment
Below, will combine accompanying drawing partly preferred embodiments of the present invention to be elaborated.
Please refer to Fig. 2, represented the calculator system of shared storage facilities of the present invention among the figure.System comprises first controller 210 and second controller, 220, the first controllers 210 link to each other with second controller 220 through interface channel 230.Wherein, connecting channel 230 can connect or other connected mode for Ethernet, SAS.First controller 210 and second controller 220 are connected to external network 250 again respectively, and external network 250 can be Ethernet, fiber channel or other network.
As shown in Figure 2, first controller 210 and second controller 220 are shared three entity storage device HDD1, HDD2 and HDD3.Corresponding to three entity storage device HDD1, HDD2 and HDD3, there are three logic storage equipment DG1, DG2 and DG3.Wherein, logic storage equipment DG1 and DG2 conduct interviews through first controller 210, and logic storage equipment DG3 conducts interviews through second controller 220.
In order to realize the object of the invention, store flux monitor module 211 in 210 operations one first of first controller, in order to keep watch on and direct flowing of access and the dereference flow of adding up 210 couples of logic storage equipment DG1 of first controller and DG2.Store flux monitor module 221 in 220 operations one second of second controller, in order to keep watch on and direct flowing of access and the dereference flow of adding up 220 couples of logic storage equipment DG3 of second controller.In addition, system also comprises an interconnection flux monitor module 240, is positioned at first controller 210 or second controller 220.Interconnection flux monitor module 240 is in order to keep watch on the data passes flow of connecting channel 230; When the data passes flow of connecting channel 230 surpasses a threshold values; Inquire about the statistics of first controller 210 and second controller 220, the dereference flow is switched to another controller greater than the direct direct access right of the storage facilities of flowing of access.
In execution mode shown in Figure 2, interconnection flux monitor module 240 is positioned at first controller 210.When the data passes flow that detects connecting channel 230 when interconnection flux monitor module 240 continues to surpass a threshold values; Interconnection flux monitor module 240 is to first storage flux monitor module 211 request logic storage equipment DG1 that are positioned at first controller 210 and the statistics of DG2, to the statistics of the second storage flux monitor module, the 221 request logic storage equipment DG3 that are positioned at second controller 220.According to statistics, interconnection flux monitor module 240 inquiry dereference flows are greater than the logic storage equipment of direct flowing of access.At this; The dereference flow of logic of propositions storage facilities DG2 and logic storage equipment DG3 is greater than direct flowing of access; Other says it, and to logic storage equipment DG2, the dereference flow through second controller 220 is greater than the direct flowing of access through first controller 210; And to logic storage equipment DG3, the dereference flow through first controller 210 is greater than the direct flowing of access through second controller 220.Because dereference comes Data transmission through connecting channel, thereby cause the internal network pressure between controller to increase.Given this, the dereference flow is switched to another controller greater than the direct direct access right of the storage facilities of flowing of access, can significantly reduce the data passes flow between controller.Thereby, switch (failover) through losing efficacy logic storage equipment DG2 is switched to second controller 220, logic storage equipment DG3 is switched to first controller 210.
Please refer to Fig. 3 now, it has shown method flow diagram of the present invention.Below will combine Fig. 2 and Fig. 3 to describe method of the present invention.
Method of the present invention is used to control the visit of first controller 210 and 220 pairs of a plurality of entity storage devices of second controller (HDD1, HDD2 and HDD3), and first controller 210 is connected to second controller 220 through interface channel 230.Corresponding to three entity storage device HDD1, HDD2 and HDD3, there are three logic storage equipment DG1, DG2 and DG3.Wherein, logic storage equipment DG1 and DG2 conduct interviews through first controller 210, and logic storage equipment DG3 conducts interviews through second controller 220.
Method of the present invention comprises following steps: keep watch on direct flowing of access and dereference flow (step 300) with statistics 210 couples of logic storage equipment DG1 of first controller and DG2.Keep watch on direct flowing of access and dereference flow (step 310) with 220 couples of logic storage equipment DG3 of statistics second controller.Keep watch on the data passes flow (step 320) of connecting channel 230; Whether the data passes flow of judging connecting channel 230 surpasses a threshold values (step 330); When the data passes flow of connecting channel 230 surpasses a threshold values; Inquire about the statistics (step 340) of first controller 210 and second controller 220, then the dereference flow is switched to another controller (step 350) greater than the direct direct access right of the storage facilities of flowing of access; When the data passes flow of connecting channel 230 does not surpass a threshold values, return step 320.
Particularly, when the data passes flow that detects connecting channel 230 continued to surpass a threshold values, the statistics of asking logic storage equipment DG1 and DG2 to first controller 210 respectively was to the statistics of second controller, 220 request logic storage equipment DG3.According to statistics, inquiry dereference flow is greater than the logic storage equipment of direct flowing of access.At this; The dereference flow of logic of propositions storage facilities DG2 and logic storage equipment DG3 is greater than direct flowing of access; Other says it, and to logic storage equipment DG2, the dereference flow through second controller 220 is greater than the direct flowing of access through first controller 210; And to logic storage equipment DG3, the dereference flow through first controller 210 is greater than the direct flowing of access through second controller 220.Because dereference comes Data transmission through connecting channel, thereby cause the internal network pressure between controller to increase.Given this, the dereference flow is switched to another controller greater than the direct direct access right of the storage facilities of flowing of access, can significantly reduce the data passes flow between controller.Thereby, through the switching of losing efficacy logic storage equipment DG2 is switched to second controller 220, logic storage equipment DG3 is switched to first controller 210.
