Title:
REMOTE DATA REPLICATION METHOD, STORAGE DEVICE AND STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/076633
Kind Code:
A1
Abstract:
A remote data replication method, a storage device and a storage system. A first controller detects whether there is a replication task at the locality; when there is no replication task in the first controller, the first controller sends a request message to the second controller; the request message is used for applying to the second controller for an application task, and the second controller comprises at least two replication tasks; the second controller reads data corresponding to a first replication task according to the request message and sends same to the first controller; and the first controller receives the data corresponding to the first replication task and sends the data corresponding to the first replication task to a disaster backup array, and the second controller sends the data corresponding to the second replication task to the disaster backup array. Accordingly, the purpose of parallel data replication in a multi-variable control system is achieved.
