Abstract

The invention discloses a data migration method and device. The data migration method and device are applied to a distributed storage system. The method comprises the steps that a first server node receives a first data migration request sent by a second server node or sends a second data migration request to the second server node, wherein the load of the first server node is larger than that of the second server node; the first server node sends data to be migrated to the second server node through a data reproduction pipeline, wherein the data reproduction pipeline is a data transmission link between the first server node and the second server node; within the preset time interval before data migration is completed, the first server node stops providing the data access service for a client side temporarily. Through the data migration method and device, operation of a distributed storage system can be more efficient.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data migration method and device. Background technique [0002] Cloud Computing is Grid Computing, Distributed Computing, Parallel Computing, Utility Computing, Network Storage Technologies, Virtualization It is the product of the integration of traditional computer technology and network technology such as Load Balance, which aims to integrate multiple relatively low-cost computing entities into a system with powerful computing capabilities through the network. Distributed storage is a field in the field of cloud computing, and its role is to provide distributed storage services for massive data and high-speed read and write access capabilities. [0003] The distributed storage system is composed of management nodes, several server nodes and clients connected to each other. The management node is responsible for monitoring the operation of the system, and provides the func...
