There are two modes of operation according to the difference in copy units:
Replication operation in units of logical volumes (method with GDS Snapshot)
Replication operation in units of slices (method without GDS Snapshot)
For details on how to confirm and select the type of operation, refer to the section titled "3.8.1.1 Configuring the unit of SDX object operations". Replication in units of logical volumes (method with GDS Snapshot) is applicable only to replication within a server.
For replication between servers, you must use units of slices.
Note
The two types of operation cannot be performed on a single Managed Server.
