Remote Interfaces

This section describes each remote interface.
■ FC (Fibre Channel)
Data is transferred between multiple ETERNUS DX Disk storage systems by using host interfaces. The ETERNUS
DX Disk storage system can be connected to the destination storage system directly or via switch. A digital
service unit is required for a remote connection that is using a line. Two types of host interfaces with a
maximum transfer speed of either 16Gbit/s or 8Gbit/s are available.

■ iSCSI
Data is transferred between multiple ETERNUS DX Disk storage systems by using host interfaces. Direct
connection to a WAN is possible.
Two types of host interfaces with a maximum transfer speed of either 10Gbit/s or 1Gbit/s are available.
