RAID controller
Each RAID controller contains several connectors and LEDs. Each
controller has two host ports and one expansion port for connecting the
storage server to hosts or expansion units. You first insert SFPs into the
ports and then connect the fibre channel cables.
Note: The DS4300 single-controller storage server (model 6LU and 6LX)
contains only one RAID controller and does not contain any
expansion ports.
Host ports
The host ports are used to connect a fibre channel cable from the host
systems. You first insert an SFP into the port and then connect a fibre
channel cable. The two host ports in each controller are independent. They
are not connected in the controller module as they would be in a hub
configuration.
Ethernet port
The Ethernet port is for an RJ-45 10BASE-T or 100BASE-T Ethernet
connection. Use the Ethernet connection to directly manage storage
subsystems.
Expansion port
The expansion port is used to connect additional expansion units to the
RAID controllers. You first insert an SFP into the port and then connect a
fibre channel cable.
Note: There are no expansion ports on the DS4300 single-controller storage
server (model 6LU and 6LX).
Serial port
The serial port is used by service personnel to perform diagnostic
operations on the RAID controller or controllers.
