Embodiment Construction
[0057] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0058] The technical background of the embodiment of the present invention is first introduced below.
[0059] A distributed storage system is to disperse and store data on multiple independent devices and centrally manage storage services. The distributed storage system includes storage nodes, and the storage nodes may include multiple block storage units, such as storage systems such as virtual disks and logical volumes. In the embodiment of the present invention, the storage node may be an EBS storage node, and the EBS storage node may divide a storage unit into multiple block storage units. The distributed storage system also includes a client, and the client can request to ...

The invention discloses a data processing method of a distributed storage system and a distributed storage system, which are used for improving the access efficiency of the distributed storage system. Wherein, the data processing method of the distributed storage system includes: the client sends an access request message to the management server; wherein, the access request message is used to request access to the block storage unit included in the elastic block storage EBS storage node; the client receives The mapping relationship fed back by the management server; wherein, the mapping relationship includes a mapping relationship between a block storage unit and a volume group, and a mapping relationship between a volume group and a target; wherein, a target corresponds to at least one volume group, and a volume group corresponds to at least one A block storage unit; the client accesses any block storage unit of a volume group specified by any target in the at least one target according to at least one target corresponding to the mapping relationship; wherein, the specified volume group is the The management server assigns the volume group to the client in advance.
Description
technical field [0001] The invention relates to the technical field of cloud storage, in particular to a data processing method of a distributed storage system and a distributed storage system. Background technique [0002] A distributed storage system is a storage system that disperses and stores data on multiple independent devices and centrally manages storage services, such as virtual disks and logical volumes. Usually, the user performs data transmission in the distributed block storage system based on the Internet Small Computer System Interface (iscsi) protocol. Among them, the iscsi protocol is a protocol based on TCP / IP, which is used to establish and manage the mutual connection and data transmission between the iscsi server (target) and the iscsi client (initiator). [0003] In an existing distributed storage system, the iscsi server creates multiple targets, and exports each target to a corresponding client. In this way, the client can access the storage unit o...
