Host Interfaces
A host interface (CA) is an adapter that has interface ports to connect a controller to a server.
The following table shows the maximum number of host interfaces that can be installed per controller.
Table 86 Maximum Number of Host Interfaces per Controller
Model Maximum number of host interfaces
ETERNUS DX60 S5 1
ETERNUS DX100 S5 2
ETERNUS DX200 S5 2
ETERNUS DX500 S5 2
ETERNUS DX600 S5 4
ETERNUS DX900 S5 4
Host interfaces can be added during system operation. When an error occurs, a replacement can be made while
the system is running.
FC, iSCSI, and SAS are available as the SAN host interface. Ethernet is available as the NAS host interface.
Different types of interfaces can exist together in the same controller.
The host interface specifications are shown below.
