Abstract

The invention discloses a data storage method and device based on a cloud storage system. The method comprises the steps that storage node addresses and data object addresses are calculated by means of an enhanced hash function; the storage node addresses are made to correspond to the data object addresses through a ring-shaped hash addressing space; when data is received, the storage node addresses are calculated by means of the enhanced hash function, and then the data is stored into storage nodes corresponding to the storage node addresses. According to the data storage method and device based on the cloud storage system, super-large scale storage and extension problems can be solved, it can be guaranteed that physical node address spaces are uniformly distributed in the system, system load balancing is improved, and efficient positioning of data organization is achieved.

Description

technical field [0001] The invention belongs to the technical field of cloud storage, and in particular relates to a data storage method and device based on a cloud storage system. Background technique [0002] In modern storage systems, due to the continuous increase in the total amount of data information, the storage capacity ranges from PB to EB, the data processor is getting faster and faster, and the speed of various links is also getting faster and faster, but the data distribution mechanism has become short The dynamic expansion of the storage scale cannot keep up with the processing speed in time, which will easily cause system downtime, system suspended animation and other related states. And a lot of application data needs the support of the database, and the performance of data processing is deeply affected. [0003] Traditional data distribution strategies are based on high-throughput network technology, which is stable and low-cost, but the speed cannot keep u...
