Abstract

The invention discloses a consensus method and a consensus system for redundant storage resources based on a computing storage separation framework, which effectively improve the availability of a cluster system, and particularly improve the utilization rate of the redundant storage resources of a Raft consensus cluster under the computing storage separation framework under the condition that available computing resources are few. A data replication technology based on a common consensus technology excessively depends on redundant computing resources, and the utilization rates of computing and storing the two redundant resources are lack of balance. According to the method, the log copying and Leader node election processes in the consensus process are completed by means of the redundant storage resources, so that the system availability of the cluster is ensured by means of the redundant storage resources when available computing resources are insufficient. When the method is applied to a cloud computing environment, the result shows that the system availability of the cluster is effectively improved, and meanwhile, the security of data is ensured.

Description

technical field [0001] The invention relates to a consensus method and system for redundant storage resources under the framework of separation of computing and storage, and belongs to the technical field of electronic digital data processing. Background technique [0002] With the rapid growth of the number of Internet applications, various types of data have shown explosive growth, and the data volume of major companies has reached the EB / ZB level. In order to prevent single-point storage from becoming the bottleneck of high availability and high expansion of the system, distributed data systems usually use data replication technology, that is, to save multiple copies of the same data on multiple physical nodes. The introduction of data copy shortens the distance between the user and the server and reduces the delay of access. Moreover, it avoids the system crash caused by a single point of failure under high concurrent access, and improves the availability and fault tole...
