Fujitsu ETERNUS DX100 S3 - Remote Interfaces; Figure 90 an FC Connection for a Remote Copy between ETERNUS DX;AF Storage Systems (When Redundant Paths Are Used); Figure 91 an FC Connection for a Remote Copy between ETERNUS DX;AF Storage Systems (When Lines Are Used)

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 three different maximum transfer rates (32Gbit/s, 16Gbit/s, and 8Gbit/s) are
available for the
ETERNUS DX100 S4/DX200 S4.
Host interfaces with two different maximum transfer rates (16Gbit/s and 8Gbit/s) are available for
the ETERNUS DX100 S3/DX200 S3.
