Remote Connections
■
Fibre Channel (FC)
Data transfer is performed between multiple ETERNUS AF/DX storage systems by using the host interface. The
ETERNUS AF/DX can be connected to the destination storage system directly or with the switch. A digital service
unit is required for remote connections if a line is used.
Host interfaces with two different maximum transfer rates (32Gbit/s and 16Gbit/s) are available.

iSCSI
Data transfer is performed between multiple ETERNUS AF/DX storage systems by using the host interface. Direct
connections to a WAN are possible.
Host interfaces with two different maximum transfer rates (10Gbit/s and 1Gbit/s) are available.

Caution
The IPsec function is not supported for iSCSI interfaces.
Select a LAN switch with the IPsec function to use the IPsec function to perform a remote copy.
