Страница: 42 / 164

connects DS4000 EXP storage expansion enclosures to the storage
server.) You first insert SFPs into the ports and then connect the Fibre
Channel cables.
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 (Model 60U/60X only)
The expansion port is used to connect up to three DS4000 EXP storage
expansion enclosures to the RAID controllers. You first insert a SFP into the
port and then connect a fibre channel cable.
Note: If you want to connect up to seven DS4000 EXP storage expansion
enclosures, you must purchase the DS4300 Turbo option. See
Table 8 on page 4 for more information.
Serial port
The serial port is used by service personnel to perform diagnostic
operations on the RAID controllers.
Server/Enclosure ID switch
The Server ID switch settings range from 0 through 7, and you can set
unique IDs ranging from 00 through 77.
Note: DS4300 storage server and the DS4000 EXP storage expansion
enclosures are shipped with their Server ID/Enclosure ID switches
set to 0 as the default. If you want to connect a DS4300 to one or
more EXP storage expansion enclosures, you must set the
Enclosure IDs of the EXPs to unique values (other than 0 or the
current Server ID setting of the DS4300 storage server).
Note: For controller firmware version 05.33.xx.xx, both host and expansion ports
operate at 2 Gbps only. For controller firmware version 05.34.xx.xx and
higher, the host ports can operate at either 1 or 2 Gbps (the expansion port
speed is still locked at 2 Gbps only).
