The following table describes the cables required to perform storage system connections
at the time of installation.
Interface
type Connector type Cable requirements
Fibre
Channel
LC-LC Use a Fibre Channel cable to connect the
Fibr
e Channel ports on each controller to
a host computer (direct connection), or to
or several host computers via a Fibre
Channel switch. See the note and table
below.
iSCSI
(optical)
LC-LC Use an optical Ethernet cable to connect
the iSCSI 10 Gb SFP ports on each
controller to a host computer (direct
connection), or to several host computers
via an Ethernet switch.
iSCSI
(copper)
RJ-45 Use a shielded Category 5e or 6a Ethernet
cable to connect the iSCSI 10 Gb RJ-45
ports on each controller to a host
computer (direct connection), or to
several host computers via an Ethernet
switch.
SAS SAS optical Connects the controller to a drive tray or
a drive tray to another drive tray. Two SAS
cables are provided with each drive tray.
SAS cables are also used to connect NAS
modules to switches.
Ethernet RJ-45 Four shielded Category 5e or 6a Ethernet
cables are required for connecting the
SVP to the controllers, management
console PC, and network switch.
Note: The maximum distances in a typical Fibr
e Channel SAN depend on the
kind of optical ber used and its diameter. The following table lists the
maximum supported Fibre Channel cable length based on cable size and port
speed.
Cable size Speed Maximum cable length
9 micron 1 Gbps 3281 feet
(1 km)
2 Gbps 6562 feet
