Lower obtained every other embodiment, broadly falls into the scope of protection of the invention.
Shown in Figure 1, a kind of structural representation of the control system of the server cluster being provided by the embodiment of the present invention
Figure, this system includes the first controller group 110, the second group controller group 120 and the 3rd controller group 130, each two controller
Communicate to connect between group, second controller group 120 is the calamity preparation controller group of the first controller group 110.
Wherein, the first controller group 110, for carrying out high availability work in server cluster, executes control task；
Second controller group 120, for when the first controller group 110 breaks down, adapter the first controller group 110
Control task；
3rd controller group 130, for determining the communication between the first controller group 110 and second controller group 120
When link breaks down, according to the current operating state of the first controller group 110, determination is to be continued by the first controller group 110
Work or the control task by second controller group 120 adapter the first controller group 110.
In embodiments of the present invention, the control system of server cluster includes three controller groups, the respectively first control
Device group 110, second controller group 120 and the 3rd controller group 130, each controller group can comprise one or more controls
Device.Communicate to connect between each two controller group, transmission and the working state monitoring of message can be carried out.Second controller group
120 is the calamity preparation controller group of the first controller group 110.
In embodiments of the present invention, the first controller group 110 carries out high availability work in server cluster, executes control
Task processed.Second controller group 120 as the calamity preparation controller group of the first controller group 110, by with the first controller group 110
Between communication link, can know whether the first controller group 110 currently breaks down.Occur in the first controller group 110
During fault, second controller group 120 can adapter the first controller group 110 control task.
3rd controller group 130 is communicated to connect with the first controller group 110 and second controller group 120 respectively, when first
When communication link between controller group 110 and second controller group 120 breaks down, the first controller group 110 and second is controlled
Device group 120 processed all can send corresponding fault message to the 3rd controller group 130, and the 3rd controller group 130 is according to the first control
Device group 110 processed and/or the fault message of second controller group 120 transmission, you can determine the first controller group 110 and the second control
Communication link between device group 120 breaks down.
3rd controller group 130 can determine the first controller by the communication link between the first controller group 110
The current operating state of group 110.And then can determine and controlled by first according to the current operating state of the first controller group 110
Device group 110 works on or the control task by second controller group 120 adapter the first controller group 110.3rd controller
Group 130 alternatively referred to as arbitration controller group.Second controller group 120 so can be avoided cannot to know the first controller group
During 110 working condition, fight for shared resource with the first controller group 110.
As shown in Fig. 2 being the first controller group and second controller group operating diagram.Site1 be the first controller group,
Site2 is second controller group, has communication link between site1 and site2.When this communication link is in normal connected state
When, by this communication link, site2 can know whether site1 currently breaks down.In this case, the 3rd controller group
Any operation can not be carried out.When this communication link breaks down, site1 and site2 can send event accordingly to site3
Barrier information, as shown in figure 3, being arbitrated by site3, determination is to be worked on by site1 or by site2 adapter site1
Control task.
The system that the application embodiment of the present invention is provided, communicates to connect between each two controller group, the 3rd controller group
When determining that the communication link between the first controller group and second controller group breaks down, can be according to the first controller group
Current operating state, determination is to be worked on by the first controller group or by second controller group adapter the first controller group
Control task, it is to avoid second controller group and the first controller group fight for shared resource, cause in server cluster data not
Unanimously, affect the normal work of server cluster.
In a kind of specific embodiment of the present invention, the 3rd controller group 130 can be specifically in the first controller
When group 110 is not presently within normal operating conditions, determine by the control of second controller group 120 adapter the first controller group 110
Task.
Communication link between determination the first controller group 110 and second controller group 120 for the 3rd controller group 130 is sent out
Raw fault, and when the first controller group 110 is not presently within normal operating conditions, the 3rd controller group 130 can determine first
Controller group 110 there occurs fault, and then can determine by the control of second controller group 120 adapter the first controller group 110
Task.
In another kind of specific embodiment of the present invention, the 3rd controller group 130 can be specifically in the first control
When device group 110 is currently at normal operating conditions, determines and worked on by the first controller group 110.

Raw fault, but when the first controller group 110 is currently at normal operating conditions, the 3rd controller group 130 only can determine currently
It is only that communication link between the first controller group 110 and second controller group 120 there occurs fault, and the first controller group
110 do not break down, and are worked in such a case, it is possible to determine by the first controller group 110.
In a kind of specific embodiment of the present invention, the 3rd controller group 130 is additionally operable to work as in the first controller group 110
Before be in if it is determined that second controller group 120 is currently at normal operating conditions during normal operating conditions, then stop second control
The work of device group 120 processed.
Communication link between determination the first controller group 110 and second controller group 120 for the 3rd controller group 130 is sent out
Raw fault, but the first controller group 110 is currently at during normal operating conditions if it is determined that second controller group 120 is current
It is in normal operating conditions, then can stop the work of second controller group 120.Avoid second controller group 120 and the first control
Device group 110 processed fights for shared resource.
In one embodiment of the invention, the first controller group 110 can comprise the first controller and second controller,
First controller and second controller communication connection, spare controller each other.
In actual applications, the first controller can be set to master controller, second controller is set to standby control
Device processed, the first controller group 110 correspondence with foreign country is carried out by the first controller, when the first controller breaks down, starts the
Two controllers, by the task of second controller adapter first controller.
In another embodiment of the present invention, second controller group 120 can include the 3rd controller and the 4th control
Device, the 3rd controller and the communication connection of the 4th controller, spare controller each other.
Equally, in actual applications, the 3rd controller can be set to master controller, the 4th controller is set to standby
With controller, second controller group 120 correspondence with foreign country is carried out by the 3rd controller, when the 3rd controller breaks down, opens
