SCSI Ultra2 (LVD) 9-Drive Cable Kit

SCSI Ultra2 (LVD) 9-Drive Cable Kit

The SCSI Wide Ultra2 Low Voltage Differential (LVD) protocol supports a maximum 80

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 Ultra2 (LVD) Cable Kit (part number DCULTRA2-9KIT),

designed to fit the rear panel of the Data Silo® DS400 or DS500 9-bay tower or rack mount

chassis, simplifies and reduces this Ultra2 (LVD) cable length limitation.

With the DCULTRA2-9KIT installed within up to two DS400 or DS500 9-bay

chassis, any combination of up to 15 SCSI Wide Ultra2 (LVD) devices can be

supported on a single Ultra2 (LVD) channel, allowing a total maximum external

cable length of 12 meters. Without a DCULTRA2-9KIT 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 DCULTRA2-9KIT includes an Ultra2 (LVD) SCSI repeater board with internal and

external SCSI connectors, an internal power splitting cable, a crimped-on Ultra2 multi-

mode (LVD/Single-Ended) terminator, and a 9-drive internal Ultra2 (LVD) ribbon cable.

NOTE: All external SCSI cables must meet the Ultra2 (LVD) specification (for up to 80

MBytes/sec operation).
