3.2 Remote Connections
An FC or iSCSI interface is available for a remote connection.
For remote connections, different types of interfaces (FC, iSCSI 10Gbit/s, iSCSI 1Gbit/s) cannot exist together
on a REC path (connection between a local ETERNUS DX Disk storage system and a remote ETERNUS DX Disk
storage system).
When different types of remote interfaces exist in the same ETERNUS DX Disk storage system, make sure to
use the same type of interface for each REC path.
For example, the following configuration is not supported because different types of interfaces (FC/iSCSI)
exist together on a REC path.
Figure 3.7 Example of non-supported connection configuration (when multiple types of remote interfaces
are installed in the same ETERNUS DX Disk storage system)
The following configuration is supported because the same type of interface is used for each REC path.
Figure 3.8 Example of supported connection configuration (when multiple types of remote interfaces are
installed in the same ETERNUS DX Disk storage system)
