The invention provides a method and a device for data distribution and storage. The method is applied in a distributed storage system. The distributed storage system comprises a core server set and at least one peripheral server set. Each of the core server set and the peripheral server sets comprises a plurality of data nodes for storing and processing data. According to the method, after data blocks and data block copies of services to be stored are acquired, the data blocks of the services are stored in the data nodes of the core server set according to preset balanced distribution rules, and the data block copies are stored in the data nodes of the peripheral server sets. Therefore, when only the data nodes of the core server set are operated and when the data blocks are abnormal or processing quantity of data in the core server set is excessively high, a processing request is dispatched to the data nodes of the peripheral server sets; accordingly, reduction of system energy consumption is made possible while the normal access need of the system is met.
Description
technical field [0001] The present invention relates to the technical field of distributed shared storage, and more specifically relates to a data distributed storage method and device. Background technique [0002] Cloud computing is a typical network computing model, emphasizing the scalability and availability of running large-scale applications in a virtual computing environment. [0003] With the rapid development of data-intensive computing and the gradual increase in the requirements for information processing capabilities, the data of data-intensive applications are more and more widely used in cloud computing environments. Data for data-intensive applications is generally stored in a distributed shared storage environment. However, in the data distributed shared storage environment, the main factor affecting the performance of data-intensive computing is the network transmission of data. In order to reduce the network transmission of data, data-intensive calculati...
