SCSI Ultra160 Cable Kits
Ultra160 9-Drive Cable Kit
The SCSI Wide Ultra160 Low Voltage Differential (LVD) protocol supports a maximum 160
MByte/sec transfer rate for applications with up to 15 LVD devices, providing that the total
(internal plus external) device-to-host cable length does not exceed 12 meters (approx. 39
feet). The StorCase ® Technology Ultra160 9-Drive Cable Kit (P/N DCULTRA160-9KIT), de-
signed to fit the rear panel of the Data Silo ® DS500 9-bay tower or rack mount chassis, simplifies
and reduces this Ultra160 cable length limitation.
With the DCULTRA160-9KIT installed within up to two DS500 9-bay chassis, any combination
of up to 15 SCSI Wide Ultra160 devices can be supported on a single Ultra160 channel, allowing
a total maximum external cable length of 12 meters. Without a DCULTRA160-9KIT installed in
each chassis however, the chassis-internal cable lengths between devices must also be
taken into consideration, thus reducing the maximum allowable external cable length available.
The DCULTRA160-9KIT includes a SCSI Ultra160 repeater board with internal and external
SCSI connectors, an internal power splitting cable, and a 9-drive internal Ultra160 ribbon cable
with a crimped-on Ultra160 multi-mode (LVD/Single-Ended) terminator (Figure B-1).
Ultra160 5-Drive Cable Kit
The Ultra160 5-Drive Cable Kit (P/N S90A100) is also designed to fit the rear panel of the DS500
chassis. Two (2) S90A100 cable kits installed within a single DS500 allow for dual-channel
configurations. With the S90A100 kit installed within up to three DS500 9-bay chassis, any
combination of up to 15 SCSI Wide Ultra160 devices can be supported on each Ultra160
channel.
The S90A100 includes a SCSI Ultra160 repeater board with internal and external SCSI con-
nectors, an internal power splitting cable, and a 5-drive internal Ultra160 ribbon cable with a
crimped-on Ultra160 multi-mode (LVD/Single-Ended) terminator.
