Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] There are two main types of cloud storage: bulk storage and file storage.

[0038] For large block storage, it means that a large file is divided into multiple large blocks of 64MB, and the large blocks are stored in different nodes. Increase the performance of reading, thereby reducing the storage delay caused by the large file size of a single node; in this way, a dynamic management and configuration mechanism needs to be established to avoid the increase of the probability of node blocking due to the high popularity of a single large block. In addition, since the large block storage divides the file into different nodes, the entire file may become unusable due to the corruption of one of the large blocks.

[0039] For file storage, it refers to a complete file or copying multiple files and storing them in different nodes.

[0040]Due to the cloud ...

Abstract

A distribution method for distributed storage of cloud data belongs to the technical field of resource distribution and comprises the following steps: step S1, establishing a cloud platform; the cloud platform comprises a user side, a management node, a main node and a child node; the main node is used for classifying archives and setting the number of duplicates of the archives; the master node distributes the file replica to the child nodes and records the state of the file replica; step S2, a blocking pre-screening mechanism: the main node screens out child nodes of which the blocking probability BPi is smaller than a blocking probability threshold value Tbp, and a qualified node set is formed; and S3, a reference queue load balancing mechanism: in the qualified node set, the main node screens out a sub-node with the maximum reference queue residual space number RQ to serve as an optimal sub-node for file copy storage, and file copy storage is carried out. According to the scheme, three file storage configuration mechanisms with a progressive relationship are provided on the cloud platform, and dynamic copy configuration is carried out to maintain load balance between nodes.

Description

technical field [0001] The invention belongs to the technical field of resource allocation, and in particular relates to an allocation method for distributed storage of cloud data. Background technique [0002] If the file data is stored on the local end, and the corresponding data is uploaded to the cloud server for calculation when necessary, when the file data is too much, the storage space of the local end will be insufficient, thus increasing the hardware cost. Therefore, the traditional local device storage method is gradually replaced by the cloud storage method to reduce costs and improve storage performance. The cloud storage method is to store the file data in the cloud, and then download and store it through the network when necessary. [0003] Cloud storage, mostly using a decentralized architecture. In this architecture, the system usually replicates file copies to reduce the delay in responding to user requests and reduce bandwidth consumption. Therefore, in...
