Abstract

The present invention provides a data storage method and apparatus of a cluster. The method includes the following steps that: a plurality of nodes in the cluster are mapped onto a consistency Hash loop according to the network addresses of the nodes in the cluster; the data-to-be-stored write-in requests of a plurality of clients are responded, an election instruction is transmitted to the plurality of clients; the data-to-be-stored write-in requests of main writers listed by the plurality of clients are responded, the attribute information of data to be stored is determined; the data to be stored are mapped onto the consistency Hash loop according to the attribute information of the data to be stored, and nodes to store data, which are associated with the data to be stored, are determined from the plurality of nodes on the consistency Hash ring; and the network addresses of the nodes to store data are sent to the main writers. With the data storage method and apparatus of the cluster provided by the embodiments of the invention adopted, the throughput capacity of the nodes can be effectively increased under a condition that the capacity of the storage cluster is not expanded, and storage cost can be effectively saved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a cluster data storage method and device. Background technique [0002] In recent years, the Internet has developed astonishingly, and the applications of the Internet have also emerged in an endless stream. The rapid development of the Internet has put forward higher requirements for network storage. The increase in network bandwidth has led to the emergence of a large number of new applications on the Internet, such as the application of Internet live broadcasting, which further drives the development of the storage industry. [0003] In the practical application of storage technology, cluster technology is usually used to form a cluster of two or more server nodes to provide users with more efficient fault tolerance and fault recovery capabilities, increase the processing capacity of massive tasks, and thus provide more Good reliability and practicality. [0004] Taking c...
