■ Host interfaces
A host interface (CA) is a board that has interface ports to connect a controller to a server.
Up to two host interfaces can be installed in the controller of an ETERNUS DX Disk storage system. Different
types of host interfaces can exist together in the same controller. For details about the installation rules, refer
to "4.3.1 Host Interfaces" (page 70)
.
FC, iSCSI, FCoE, and SAS are available as host interface.
The following table shows the host interface specifications.
Table 1.1 Host interface specifications
■ Drive interface ports
A drive interface port is used to connect drive enclosures.
The following table shows the drive interface port specifications.

• FC and iSCSI host interfaces can be used as remote interfaces for remote connections by changing the port
mode. The port mode can be set from ETERNUS Web GUI or ETERNUS CLI.
• There are two types of iSCSI 10Gbit/s and FCoE host interfaces; an interface type with SFP+ modules (LC
connector for an FC cable connection) and an interface type without SFP+ modules (SPF+ connector for a
Copper Twinax cable connection).
• For SFP+ modules, Short Wave Length (SWL) or Long Wave Length (LWL) types can be installed in
16Gbit/s FC interfaces. The default modules that are installed in 16Gbit/s FC interfaces are SWL type SFP+
modules. To install LWL type SFP+ modules, purchase the Long wave SFP+ modules for the DX80 S2/DX90
S2 separately.
