Cassette Autoloader
166504-B21
(Internal)

(External) |
| The Compaq 20/40-GB DAT 8
Cassette Autoloader includes an integrated DDS-4 DAT Drive and changer
mechanism with convenient access to an eight cassette magazine, allowing
you to develop a media management tape rotation scheme for scheduled
backups of servers 40 GB or less. |
| |
| Overview |
| Industry Standard DDS-4 |
| The DDS-4 technology has a
drum rotation speed of 8,503 rpm while the tape moves at 11.6 mm/s.
Features of the format allow a linear bit density greater than DDS-3,
which increases transfer rate and capacity. |
| |
| Investment Protection |
| The 20/40-GB DAT autoloader
uses a compatibility mode to read and write DDS-1, DDS-2, DDS-3 and
DDS-4 tapes. This offers investment protection for users who have
standardized with the DAT technology. Users will also have the ability
to restore archived media from previous backups and interchange with
previously shipping Compaq DDS-3 6 and 8 cassette Autoloader drives. |
| |
| Lowers TCO with
Automation |
| Automated DAT backup
systems offer lower total cost of ownership with a higher storage
capacity and performance than a stand alone tape backup drive and is
targeted at the price sensitive environments. |
