Problems solved by technology

[0005] If the user cannot make full use of the allocated space, it will cause a waste of storage space; if the existing storage space is insufficient, it is difficult to expand
Therefore, existing solutions basically cannot effectively utilize storage resources

Embodiment Construction

[0033] The present invention is described in more detail below by means of examples, but the following examples are only illustrative, and the protection scope of the present invention is not limited by these examples.

[0034] In order to achieve the purpose of the present invention, the system structure based on this example includes three client manager (Client Agent, CA), storage resource manager (Storage Resource Manager, SRM) and storage resource agent (Storage Resource Agent, SRA) part.

[0035] The client manager (Client Agent, client manager), that is, the application server. The main function is to apply to a storage resource manager (Storage Resource Manager, storage resource manager) for a storage device meeting a condition or to release an idle storage device.

[0036] Storage Resource Manager (Storage Resource Manager, Storage Resource Manager), the main function is to organize the Storage Resource Agent (Storage Resource Agent, Storage Resource Agent) described...

Abstract

The invention discloses a user-oriented dynamic storage resource distribution method. The method can dynamically increase a storage pool, and meanwhile can supply a storage space with size as a user required to a client. The method comprises that: (1) a storage resource agent sends physical volume set information to a storage resource manager; (2) the storage resource manager updates an information link list of the storage resource agent, and periodically detects the heartbeat of the storage resource agent; (3) a client agent sends physical volume application information or physical volume release information to a storage resource server according to the demand of the user; and (4) the storage resource manager receives the information of the client agent: a, if the information is the physical volume application information, the storage resource manager automatically distributes a physical volume to the client agent, and the client agent automatically establishes ISCSI connection to the distributed physical volume to acquire storage resources; and b, if the information is the physical volume release information, the storage resource manager reclaims the physical volume. The method has the advantages that the storage resource manager can automatically distribute or reclaim the storage resources for the client agent as the user required, and intervention of an administrator is not needed.

Description

technical field [0001] The invention belongs to the field of network storage, in particular to a user-oriented method for dynamically allocating storage resources based on the iSCSI protocol. Background technique [0002] ISCSI (internet SCSI) is a set of commands that define the transmission of the SCSI protocol on the TCP / IP network, and is used to transmit SCSI commands and data between the client and the storage system. Currently, the ISCSI technology has been standardized and widely used. [0003] A typical application of the ISCSI protocol is that the client installs an ISCSI initiator module, and the storage server installs an ISCSI target module. The client encapsulates SCSI commands / data into iSCSI packets and sends them to the storage system through the IP network. The storage service system processes each ISCSI message, takes out the data in it and writes it into the storage medium. [0004] Currently, allocating storage resources through ISCSI usually allocate...
