The following table describes the cables required to perform storage system connections
at the time of installation.

Cable requirements
Fibre
Channel
LC-LC
Use a Fibre Channel cable to connect the
Fibre 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.
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 Fibre Channel SAN depend on the
kind of optical fiber used and its diameter. The following table lists the
maximum supported Fibre Channel cable length based on cable size and port
speed.
