SCSI Ultra320 Cable Kits
NOTES: For SCSI Ultra320 operation, the StorCase® Ultra320 cable kits require
Ultra320 9-Drive Cable Kit
The SCSI Wide Ultra320 Low Voltage Differential (LVD) protocol supports a maximum
320MB/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 Ultra320 9-Drive Cable Kit (P/N S90A114), designed to fit
the rear panel of the Data Silo® DS400 or DS500 9-bay tower or rack mount chassis, simplifies
and reduces this Ultra320 cable length limitation.
With the S90A114 installed within up to two DS400 or DS500 9-bay chassis, any combination of up to 15 SCSI Wide Ultra320 devices can be supported on a single Ultra320 channel,
allowing a total maximum external cable length of 12 meters. Without an S90A114 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 S90A114 includes a SCSI Ultra320 repeater board with internal and external SCSI
connectors, an internal power splitting cable, and a 9-drive internal Ultra320 ribbon cable with
a crimped-on Ultra320 multi-mode (LVD/Single-Ended) terminator (Figure 1).
Ultra320 drives, Ultra320 HBA, and Ultra320-compliant cabling (internal
and external).
For daisy-chained SCSI Ultra320 removable drive applications,
StorCase Ultra320 Data Express removable drive enclosures must also
be used in conjunction with the Ultra320 cable kits.
Ultra320 5-Drive Cable Kit
The Ultra320 5-Drive Cable Kit (P/N S90A113) is also designed to fit the rear panel of the
DS400 or DS500 chassis. Two (2) S90A113 cable kits installed within a single DS400 or DS500
allow for dual-channel configurations.
With the S90A113 kit installed within up to three DS400 or DS500 9-bay chassis, any
combination of up to 15 SCSI Wide Ultra320 devices can be supported on each Ultra320
channel.
The S90A113 includes a SCSI Ultra320 repeater board with internal and external SCSI connectors, an internal power splitting cable, and a 5-drive internal Ultra320 ribbon cable with
a crimped-on Ultra320 multi-mode (LVD/Single-Ended) terminator(Figure 2).

INSTALLATION
(see figure on next page)
NOTES: For SCSI Ultra320 operation, the StorCase® Ultra320 cable kits require
1. Disconnect ALL power and remove cables from the Data Silo chassis.
2. Open the Data Silo chassis to gain access to the internal cables and rear panel I/O
connectors. Refer to the Data Silo User's Guide if necessary for information on this
procedure.
3. Remove existing internal SCSI ribbon cable if installed.
4. Verify that ALL devices within the Data Silo chassis have termination disabled.
5. Remove existing chassis rear panel connector(s) if necessary. Save mounting screws,
these will be used in Step 7.
6. Attach one end of the power cable to the SCSI Ultra320 board, attach the other end
to the Data Silo power strip. The position of existing device power cables may
need to be adjusted to accommodate the power cable.
7. Attach the SCSI Ultra320 repeater board to the Data Silo rear panel with the same
screws saved from Step 5, component-side facing into the Data Silo chassis (Figure
3).
8. Connect the internal SCSI ribbon cable to the SCSI Ultra320 board and installed devices.
Ultra320 drives, Ultra320 HBA, and Ultra320-compliant cabling (internal
and external).
For daisy-chained SCSI Ultra320 removable drive applications,
StorCase Ultra320 Data Express removable drive enclosures must also
be used in conjunction with the Ultra320 cable kits.
NOTE: Do not skip connectors on the internal SCSI ribbon cable when connecting
9. Reinstall the Data Silo covers and cables removed earlier.
10. For daisy-chaining multiple Data Silo chassis, verify that the individual external SCSI
cables meet the SCSI Ultra320 (320MB/sec) Specification and that total device-tohost cable length does not exceed 12 meters (approx. 39ft).
