Embodiment
As shown in Figure 1, system of the present invention comprises cloud resource unified management interface, cloud platform news network, cloud controller, storage control, storage server and virtual machine.
Cloud resource unified management interface (Portal), Portal is the operation interface that G-Cloud offers the user, the user can realize the related services such as application, use, the cancellation operation of cloud resource in Portal.Can respond user's elastic storage demand.
Cloud platform news network, the application be take G-Cloud cloud platform and is example; G-Cloud is a distributed system, comprises many distributed modules, and message transmission and security control thereof between modules are all realized by the G-Cloud news network.Various message in elastic storage request processing procedure all will be by this network delivery.
Cloud controller (CLC), CLC are Resource Control Center and the message retransmission center of G-Cloud system.The hardware resource of whole system, user ask, system responses all will be by CLC unified management and processing.The resource status of CLC to lower reading system, to upper acceptance and the resource request of processing the user, CLC will do verification and preliminary treatment to these requests, by continuing to be issued to each storage control.
Storage control (SC), SC are the storage resources control centre of system, and SC provides the memory access interface, can access and the control store system, and can process all storage resource requests of user by United Dispatching, and report the storage resources situation to CLC.
Storage server, storage system provides the piece stores service for whole system, can use various SAN storage schemes to realize.Such as: the ISCSI storage realization of FC-SAN storage system, ISCSI-SAN storage hardware, REDHAT etc.
Virtual machine, virtual machine are typical case's application of cloud platform, are to use software and hardware technology virtual computer server out on the unified hardware resource basis of cloud platform.Virtual machine is the service that the cloud platform provides.
The present invention is based on G-Cloud cloud platform and realize, through the G-Cloud news network, send to the unified processing of SC after user's elastic storage request sends by Portal, SC has realized the interface of unified storage, sends memory command and processes to the bottom storage system.After storage system is disposed, by the G-Cloud news network, turn back to the user by SC, and send instructions to by CLC the storage that user's directly use system of virtual machine provides.
The memory access interface that SC provides, the storage bottom is by concrete stores service realization, and the present invention uses iscsi-san to realize, uses the tgtd issue logic volume piece storage of redhat, uses logical volume block to store by iscsid.As shown in Figure 2, performing step is as follows:
The first step, the user logins G-Cloud administration interface Portal and sends the storage resource request order, may be for applying for storage, expand storage, reducing dependent instructions such as storing, abandon storage.
Second step, the storage instruction sends to cloud controller CLC, and CLC is the resource management control centre of system, and CLC will carry out the preliminary treatment such as authority detection to user's storage instruction.
The 3rd step, memory command send to storage control SC and process, and SC is the storage control centre of G-Cloud, and complicated unified management storage resources comprises the associative operations such as storage size, free space, the logical volume of using space, issue, logical volume deletion.User instruction is responsible for sending to storage system and is received its return messages by SC.
The 4th step, used the dd order of Linux to obtain corresponding memory space, as the storage medium of piece storage.
The 5th step, used the losetup order carry memory space of Linux to winding equipment.
The 6th step, the lvm tool management partition information of use Linux, meet the subregion requirement of user to storage.
The 7th step, used the tgtd service issue logic of Linux to roll up.For the logical volume block service is provided in network environment, the application uses tgtd to realize that logical volume block storage issues in the iscsi mode.
The 8th step, in the physical machine of virtual machine place, used the iscsid service discovery and use the logical volume of issuing.
