Specific embodiment
Below in conjunction with attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually exist
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but it is merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Referring to Fig. 1, virtual disk creation method provided by the embodiment of the present invention, applied to distribution as shown in Figure 1
It include virtual disk creating device, multiple IP address resource pools, multiple ports in the distributed memory system in storage system
Resource pool and multiple memory resource pools.The memory resource pool is stored with storage resource, and the IP address resource pool is stored with
IP address resource, the port resource pond are stored with port address resource.
Referring to Fig. 2, a kind of virtual disk creation method provided in an embodiment of the present invention, is applied to distributed storage system
System, the distributed memory system includes virtual disk creating device, which comprises
Step S101: the virtual disk creating device obtains creation instruction, and the creation instruction, which carries, to be created
The demand information of virtual disk.
In practice process, the creation instruction that virtual disk creating device obtains can be issued on computers by user,
Correspondingly, sending creation instruction for the ease of user, it is additionally provided with instruction sending unit on that computer, described instruction is sent
Process communication between unit and this virtual disk creating device.
Step S102: it according to the demand information in the virtual disk index information pre-established, chooses and the need
The target virtual disk of information matches is asked to configure index information, the virtual disk configuration index information is associated with creation virtual magnetic
The information for the configuration resource that disk needs.
In practice process, when virtual disk creating device provided in this embodiment obtains the desire carried for sending instruction
When the demand information of the virtual disk of creation, for the ease of quickly creating virtual disk by the demand information, in systems, in advance
First establishing has virtual disk index information, and the virtual disk index information is associated in advance with demand information.When virtual disk is created
After building device acquisition demand information, by being matched with virtual disk index information, it can be obtained creation virtual disk needs
Configuration resource information.
