Document Type and Number:
WIPO Patent Application WO/2021/212784
Kind Code:
A1
Abstract:
A distributed storage-based live migration system, comprising, at each node, a data replica manager for managing data replicas of the present node, a storage volume manager for managing storage volumes of the present node, and a resource controller; the storage volume manager is automatically transferred to the corresponding target data field along with an application, and when detecting a transfer action of the storage volume manager and determining that the target data field is different from an original data field, the resource controller automatically generates a data replica live migration command. The present invention achieves live migration of storage replicas along with a data read and write terminal, achieves more efficient read and write in a hybrid cluster scenario, and reduces loss caused by cross-region data storage.
