Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention
Embodiment be described in detail.It should be noted that in the absence of conflict, in the embodiment and embodiment in the application
Feature can mutual any combination.
Step shown in the flowchart of the accompanying drawings can be in a computer system such as a set of computer executable instructions
It executes.Also, although logical order is shown in flow charts, and it in some cases, can be to be different from herein suitable
Sequence executes shown or described step.
Fig. 1 is a kind of flow chart of the method for processing virtual-machine data of the embodiment of the present invention, as shown in Figure 1, this implementation
Example method may include:
Step 101, the request for receiving virtual machine processing data；
Step 102 judges whether main storage device can work normally, and can such as work normally, then go to step 103, such as can not
It works normally, then goes to step 104；
Step 103, the main storage device is selected to carry out data transmission；
Step 104, a standby storage equipment is selected to carry out data transmission as main storage device.
The business High Availabitity of virtual machine may be implemented in the method for the embodiment of the present invention.
In one embodiment, in step 103, during selecting main storage device to carry out data transmission, can also include:
The data changed in the main storage device are backuped in all standby storage equipment in real time or periodically.
It in another embodiment, can also include: by institute after selecting main storage device to carry out data transmission in step 103
The data changed in main storage device are stated to backup in all standby storage equipment.
In one embodiment, when there is more standby storage equipment, one can be selected according to assignment algorithm and meets specified item
The standby storage equipment of part carries out data transmission as main storage device.
When main storage device goes offline, selected between multiple standby storage equipment one as main storage device, it may be considered that
Using storage priority attribute alternatively foundation, priority it is high be chosen as main storage device.It can also be according to storage itself
Attribute selected, such as storage IO performance is good, that can be selected as main storage device.If storing attribute all
Equally, it also can be randomly selected.After the main storage device originally to go offline repairs, storage collection is added to the selection that do not seize
Group, as standby storage equipment, the data of synchronous primary storage.
In one example, as shown in Fig. 2, the system for realizing the method for processing virtual-machine data mainly may include:
Gateway refers to providing the equipment of single entrance under cloud platform for storage cluster operation；
Storage cluster, two storage equipment are included at least in this example, this two storage equipment need to realize disk mirroring
Function, in this way magnetic disk of virtual machine fall in storage equipment 1 while, can also synchronize storage equipment 2 on generate it is identical
Disk.
When virtual machine is when having IO (input and output) operation, gateway can select IO preferred path, but when excellent
When first path not can be carried out normal IO, gateway will have the ability to carry out the switching of I/O operation, be switched on alternative path.
The method of the embodiment of the present invention ensures virtual machine business High Availabitity by deployment storage dual-active, is non-to often occur reality
, it is to ensure that data consistency, this method can be used in forms data center, can also be used in across data center,
For supporting the virtual machine High Availabitity business based on storage.
