Determine the server that performs replication.
The following servers are used to perform replication:
Multiple Storage Servers are unified and operated centrally. The Storage Management Server can also be used as a Storage Server.
AdvancedCopy Manager operations are performed.
Figure 7.10 Configuration of the servers that perform replication
Note
The following requirements apply when system-to-system replication is performed using the REC function of ETERNUS disk storage systems:
The REC function must be installed in both systems.
Both 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.
Note
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.
