Remote Interfaces
Change the port mode of the host interface ports to use them as remote interfaces. For details on changing the
port mode, refer to "ETERNUS Web GUI User's Guide".
This section describes each remote interface.
■
Fibre Channel (FC)
Data transfer is performed between multiple ETERNUS DX/AF storage systems by using the host interface. The
ETERNUS DX/AF can be connected to the destination storage system directly or with the switch. A digital service
unit is required for a remote connection that is using a line.
Host interfaces with two different maximum transfer rates (32Gbit/s and 16Gbit/s) are available for the
ETERNUS
AF250 S2.
The maximum transfer rate is 16Gbit/s for the ETERNUS AF250.

iSCSI
Data transfer is performed between multiple ETERNUS DX/AF storage systems by using the host interface. Direct
connections to a WAN are possible.
The transfer rate is 10Gbit/s.
