The quantities and lengths of the cables required for storage system installation vary according to the specific storage system and network configuration. Fibre Channel and iSCSI cables are used to connect the controllers to a switch or host. Serial-attached SCSI (SAS) cables are used to connect drive trays to controllers and other drive trays.

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. |
