1 Introduction
The Certance DAT24 is a digital audio tape (DAT) drive that supports the Digital Data Storage (DDS-
3) tape format. The DAT24 drive provides a typical capacity of 24 Gbytes, assuming 2:1 data com-
pression (native capacity is 12 Gbytes).
The DAT24 tape drive can connect to a standard, single-ended SCSI or SCSI-2 interface. You can
use a 50-conductor flat cable or a 25-signal twisted-pair cable to connect the drive to a SCSI host
adapter. The cable should not exceed 6 meters (19.5 feet).
The DAT24 drive is offered as internal and desktop versions:
The internal version is available as a 3.5-inch or 5.25-inch tape drive. It provides a 50-pin,
•
dual-row single-ended SCSI connector at the back of the drive.
The desktop version provides two 50-pin, shielded connectors (ANSI Alternative 2) on the
•
back panel. These connectors consist of two rows of ribbon contacts spaced 2.16 mm
(0.085 in) apart. Either connector can be used as a SCSI IN or SCSI OUT connection.
