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 Unit of SDX Object Operations". Replication in units of logical volumes (method with GDS Snapshot) is applicable only to replication on single server.
For server-to-server replication, you must use units of slices.
Note
The two types of operation cannot be performed on a single Managed Server.
In a replication operation (method that uses GDS Snapshots) of a logical volume unit, the Storage Cluster Contiuous Copy function is not available. When using the Storage Cluster Continuous Copy function, use the replication operation (method that does not use GDS Snapshots) of a slice unit.
