Embodiment
Be described further with regard to technical scheme of the present invention below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, be the schematic flow sheet of the first embodiment of a kind of virtual data wiring method of the present invention;
It is emphasized that: process flow diagram shown in Fig. 1 is only a preferred embodiment, those skilled in the art is when knowing, any embodiment built around inventive concept should not depart from the scope contained in following technical scheme:
Receive the write request of virtual data; After the write request receiving described virtual data, obtain and produce the write object of said write request and the write attribute of said write object, determine first storage area corresponding with said write attribute; At the virtual data that described first storage area write is corresponding with said write request.Below the concrete steps that the present embodiment progressively realizes virtual data wiring method:
Step S10, receives virtual data write request;
In embodiments of the present invention, the main body performing virtual data wiring method of the present invention can be terminal (such as, server, virtual machine etc.), be further carried in the virtual data write application (such as, virtual data write software) of end side.Be preferably virtual data write application in embodiments of the present invention.
In the present embodiment, described virtual data write request can be, when carrying out data storage by the application in virtual machine or file, send, the write request of virtual data to the storage system in virtual machine.Described virtual data write request, can comprise following information: an order writing data; Article one, produce the application of described request or the address information of file.In the present embodiment, virtual data write request is received by the client utility be loaded in dummy machine system, described client utility can monitor the virtual data write request of virutal machine memory storage system, when the application in virtual machine or file send virtual data write request, described client utility just can catch described request before described request reaches storage area, and can process described request, again described request is sent after treatment, like this, all virtual data write requests of the storage system in virtual machine all can through the process of client utility.
In other embodiments of the invention, also the virtual data write request of virutal machine memory storage system can be monitored by the program segment of the information processing of hook in dummy machine system, when the application in virtual machine or file send virtual data write request, before described request reaches storage area, catch described request, preferred described program segment also can be linked up with in the storage system of described virtual machine; Or the virtual data write request of virutal machine memory storage system is monitored by the hook program of a hook in dummy machine system, when the application in virtual machine or file send virtual data write request, described request was caught before described request reaches storage area, and described request is modified, preferred described hook program also can be linked up with in the storage system in described virtual machine.
Step S20, after the write request receiving described virtual data, obtain and produce the write object of said write request and the write attribute of said write object, determine first storage area corresponding with said write attribute, said write object is the object triggering said write request;
In the present embodiment, said write object comprises application in virtual machine and file, and said write object can send virtual data write request to storage area, the virtual data that described storage area write said write object sends.Client utility in virtual machine is after the request of acquisition said write, said write request is analyzed, obtain wherein relevant with the write object producing said write request information, and determine the write object producing said write request, according to the corresponding relation of the write object preset with write attribute, determine the write attribute that said write object is corresponding, according to the write attribute preset and the corresponding relation of storage area, determine the first storage area that said write attribute is corresponding.Said write attribute includes but not limited to: storage medium, storage redundancy number, whether encrypt, whether read-only, whether visible, compression, duplicate removal.
Preferably, the client utility in described virtual machine, according to the first storage area determined, sends a virtual data write request to described first storage area.In the virtual data write request that also can be sent by write object by the client utility in described virtual machine, the information of address, pertinent storage area is modified, the first storage area is revised as in the address of pertinent storage area in request, and amended request is sent to the first storage area.
Step S30, at the virtual data that described first storage area write is corresponding with said write request.
In the present embodiment, described first storage area is after receiving the virtual data write request sent by described client utility, and described first storage area is waited for and received the virtual data corresponding with said write request that said write object sends and preserve described virtual data.Preferably, described virtual data also can be included in described virtual data write request, includes in said write request: storage area address to be written, relevant information, the virtual data to be written writing data command, write object.Described first storage area identifies the order of write data after receiving said write request, read and preserve virtual data wherein.
Adopt technique scheme, relative to prior art, by distinguishing the virtual data writing storage area in virtual machine, carry out classification to the virtual data of write storage area to store, storage space and computational resource are saved, reduce the write time delay of virtual storage system, realize the waste decreasing storage space and computational resource, reduce the difficulty of data processing and data management.
