Introduction to the Dorado SmartMigration feature


SmartMigration is a key service migration technology that migrates services from the source LUN to the target LUN without interrupting host services and enables the target LUN to take over services from the source LUN. After the service migration is complete, all service-related data has been replicated from the source LUN to the target LUN. Now, SmartMigration supports service migration not only within a storage system but also between a Huawei storage system and a compatible heterogeneous storage system.

Introduction to the Dorado snapshot feature
A snapshot is a point-in-time copy of source data. A snapshot serves as a data backup and is accessible to hosts. The snapshot features instant generation and small space occupation.

Introduction to the Dorado SmartDedupe feature
SmartDedupe is a data reduction technology. It eliminates redundant data from a storage system and reduces the required storage capacity for storing data, thereby addressing the increasing demand for storage capacity. The Dorado storage system supports inline deduplication, that is, only newly written data is deduplicated.

Whether the Dorado series SmartMigration feature requires licenses
SmartMigration is an optional value-added feature that requires a license.

Introduction to the Dorado remote replication feature
Remote replication is the core technology used for remote data synchronization and disaster recovery. The remote replication feature has two modes: Synchronous remote replication: In this mode, data is synchronized in real time to achieve full protection for data consistency and to minimize data loss in the event of a disaster. Asynchronous remote replication: Data is synchronized periodically to minimize the adverse impact on service performance caused by the long latency of long-distance data transfer.

Introduction to the Dorado Hyper features
Dorado series storage systems provide multiple data protection features, improving the data security of the storage systems and offering a solid foundation for data backup and disaster recovery. -The snapshot feature provides a mapping table for locating data so that data copies can be rapidly accessed. -Remote replication creates an available data duplicate of a local storage system almost in real time on a storage system that resides in a different region. The duplicate is instantly available without data restoration operations, protecting service continuity and data availability to the maximum extent. Remote replication is the core of the disaster recovery technology. -LUN copy is a data copy technology that quickly transfers data within a device or between devices. Clone, a type of snapshot technology, obtains fully populated point-in-time copies of source data. Clone is a backup approach that allows incremental synchronization. -HyperMetro enables that both data centers are active and bear services together to improve overall serviceability and resource utilization. -HyperMirror is a continuous data protection technology. It creates two physical mirror copies for a LUN to achieve continuous LUN backup and protection.
