Embodiment shall fall in the protection scope of this application.
The embodiment of the present application discloses a kind of data transmission method, reduces the resource consumption in data transmission procedure.
Referring to Fig. 1, a kind of flow chart of data transmission method disclosed in the embodiment of the present application, as shown in Figure 1, comprising:
S101: the data transfer command that source host is sent is received；Wherein, the data transfer command includes at least to be copied
The source address and destination address of data；
Data transmission method provided in this embodiment is applied to the storage equipment of data center, i.e. storage array, the storage
Array includes such as local replica service, local clone's service, local backup service copy service.Source host makes with destination host
Therefore data copy can be completed in the storage array with identical storage array.
In specific implementation, after source host carries out the operations such as the batch creation, deployment, backup of virtual machine, creation data are passed
Defeated order, and the data transfer command is sent to the storage queue that data to be copied store, which at least wraps
Include the source address and destination address of data to be copied.It certainly, as a preferred implementation manner, can also include data to be copied
Demand gross space, when the remaining space of destination address is unsatisfactory for the demand gross space, can simplify data transmission process.
S102: parsing the data transfer command, and the copy service of itself is called to copy the data in the source address
Shellfish is to the destination address；
In specific implementation, storage array is parsed after receiving the data transfer command of source host, to obtain data
Information in transmission order, i.e. source address, destination address etc. after being parsed, call the storage array introduced in previous step
Replicate itself service by the data copy in source address into destination address.
It is understood that parsing the number when the data transfer command includes the demand gross space of data to be copied
After transmission order, judge whether the remaining space of destination address is greater than the demand gross space；Itself is called if so, executing
Copy service by the data copy in source address to destination address the step of；If it is not, then returning to copy failure to source host
Data transmit result.
S103: result is transmitted to the source host returned data.
In specific implementation, judge whether data to be copied copy success, that is, judge in destination address with the presence or absence of wait copy
Shellfish data；Result is transmitted if so, returning to source host and copying successful data；If it is not, then returning to copy failure to source host
Data transmit result.When data copy failure when, complete data copy using data copy mode in the prior art, i.e., to
