Remote Copy replication directions

Unidirectional – If replication occurs in only one direction, the configuration is unidirectional.

Bidirectional – If replication occurs in both directions, the configuration is bidirectional. Hewlett Packard Enterprise recommends bidirectional configurations. The systems in the Remote Copy configuration serve as both primary and secondary systems. The system role depends on the Remote Copy group.
