Abstract

The invention discloses a data communication method for a distributed storage cluster. When all OSDs at each node transmit or receive data, the data transmission is achieved through the real connection built between real Messagers of the nodes, and the uploading and downloading of OSD data in the nodes are achieved through the virtual Messagers of each node. The number of connectors of the OSDs between the nodes is independent of the number of OSDs, is also independent of the number of disc positions of a single node, and is just correlated with the total number of nodes of the cluster, thereby reducing the number of connections of the cluster, and solving a problem that the cluster scale is limited because the number of connection number is too large. The invention also discloses a data communication system for a distributed storage cluster, and the system also can achieve the above technical effects.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, and more specifically, to a distributed storage cluster data communication method and system. Background technique [0002] With the increase of Internet business volume, the rapid growth of access volume and data flow, the processing intensity of each core part of the storage system is also relatively increased, which increases the system workload. The amount of information that users need to access the storage system is growing explosively. The increasing scale of the storage system has brought huge challenges to the pressure on the access server, especially for the application fields such as finance, military, and large enterprises. Once the storage system has an access failure , crashes and other catastrophic failures, enterprises will face unbearable huge losses, and the reliability of access has become an important factor to measure the overall performance of the storage...
