Determine the server that performs replication.
The following servers are used to perform replication:
Multiple Managed Servers are unified and operated centrally. The Management Server can also be used as a Managed Server.
AdvancedCopy Manager operations are performed.

Note
The following requirements apply when an inter-box replication is performed using the REC function of ETERNUS Disk storage system:
The REC function must be supported in both ETERNUS Disk storage systems.
Both ETERNUS Disk storage systems must already be connected to each other using an FC Remote Adapter (FCRA).
This is a connection that uses an FCRA, in which data flows only from the Initiator side to the Target side. For bi-directional copying, at least two FCRA connections are required.
When performing a replication between servers, if data needs to be sent to a remote site (e.g., for disaster recovery use at some time in the future) from a duplicated system like a backup server, you need to be careful with the handling of the data in the remote site so that it can be accessed correctly in the future.
