Types of Host Interfaces
The following types of host interfaces are available:

Host interface
SAN connection
NAS connection
¡: Supported ´: Not supported
●
FC
Fibre Channel (FC) enables high speed data transfer over long distances by using optical fibers and coaxial
cables. FC is used for database servers where enhanced scalability and high performance are required.
●
iSCSI
iSCSI is a communication protocol that transfers SCSI commands by encapsulating them in IP packets over
Ethernet.
Since iSCSI can be installed at a lower cost and the network configuration is easier to change than FC, iSCSI is
commonly used by divisions of large companies and by small and medium-sized companies where
scalability and cost-effectiveness are valued over performance.
●
SAS
Serial Attached SCSI (SAS) enables high speed data transfers by upgrading existing reliable SCSI connection
standards to allow serial transfers. SAS is commonly used for small-sized systems where performance and
cost-effectiveness are valued over scalability.
●
Ethernet
Ethernet is a NAS connection interface. An Ethernet network can be accessed as a file server from multiple
connected clients with different operating systems, for the easy sharing of data. The ETERNUS DX has an
internal file system for connection to existing LAN, allowing Ethernet to be installed relatively easily.
However, load on the network will increase, and therefore Ethernet is not suitable for applications that
require high transfer rates.
A Unified License is required to install Ethernet host interface. Registering the Unified License to the
ETERNUS DX enables the NAS function.
