Host Interface
Connections
The CE7900 controller tray connects to hosts through one or two host interface cards
(HICs). The CE4900 controller-drive tray has built-in (base) Fibre Channel storage
array (FC) connectors for host connections and might also have an optional HIC. The
E2600 controller-drive tray and the E2660 controller-drive tray have built-in (base)
SAS connectors for host connections and might also have an optional HIC. The
E5400 controller-drive trays (E5412, E5424, and E5460) have built-in (base) Fibre
Channel, and might also have an optional HIC for Fibre Channel connections or
InfiniBand connections. All other supported controller trays and controller-drive trays
connect through built-in ports.
