Abstract

The invention discloses a redundant link design method and system of an active-active storage system. The method includes the steps: determining whether a first data link malfunctions when monitoring that a first heartbeat link malfunctions, starting a second heartbeat link if determining that the first data link does not malfunction, and transmitting heartbeat information through the second heartbeat link; and starting the second heartbeat link and a second data link when determining that the first data link malfunctions, transmitting the heartbeat information through the second heartbeat link, and transmitting data information through the second data link. According to the above technical solution, heartbeat detection abnormity caused by abnormity of some heartbeat signal lines, abnormal communication and other reasons can be effectively prevented, the fault tolerance performance of communication lines between controllers in a storage system is great, and requirements of different application environments and network environments can be met. Therefore, multipath redundancy is achieved, and the reliability of the system and the continuity of services are guaranteed.

Description

technical field [0001] The invention relates to the technical field of a dual-active dual-control storage system, and in particular to a redundant link design method and system for a dual-active dual-control storage system. Background technique [0002] Nowadays, with the rapid development of information technology, the cornerstone role of the storage system in the IT system is more obvious. In most storage systems, there are generally two nodes (that is, two controllers), and redundant interaction between the two nodes is required. [0003] At present, the commonly used storage system is the dual-control storage system, and its working mode is the dual-control dual-active working mode (also known as the Active-Active working mode), that is, both controllers are in the active state, and can process data from the application server in parallel. Once a controller fails or goes offline, another controller will take over its work in time without affecting its existing tasks. Th...
