The new 20/40 GB
DLT Tape Drive, available as an internal or external kit, offers a transition
from the 15/30 GB DLT Tape Drive to a higher capacity and performance tape
device which has become the de facto standard in the industry. The 20/40 GB DLT
Tape Drive provides up to 20GB of native capacity on a single DLT Type IV tape
and up to 5.6GB per hour data transfer rate without compression in native mode.
With a 2:1 compression rate the 20/40 GB DLT Tape Drive provides up to 40GB of
backup capacity on a single tape at up to 10.8GB per hour data transfer rate.
The 20/40 GB DLT Tape Drive continues to offer configurations for Compaq Servers
in tower or rack mount environments, DLT tape array, or as a standalone drive.
The Compaq 20/40
GB DLT Tape Drive features backward read/write compatibility to lower capacity
10/20 and 15/30 GB DLT tapes. This feature offers investment protection for
current customers that have standardized on DLT.
The 20/40 GB DLT
Tape Drive is a thoroughly tested and integrated Compaq hardware option with
support for major industry leading backup software solutions. With this
technology being provided by Compaq, it is a very logical choice in a workgroup,
departmental server or professional workstation environment with capacity needs
in the 20GB-35GB range with the knowledge that data capacity continues to grow.

Overview
Since IS Managers and professionals are looking for higher capacity,
higher performance, and reliable tape backup, Compaq offers the 20/40-GB
DLT. DLT technology is the de facto tape backup standard in the
enterprise environment today, with the 20/40-GB DLT continuing to offer
reliability and quality to those servers with less than 40-GB of
storage. Available in both internal and external tabletop form factors,
with transfer rates up to 10.8-GB/hour (4 to 8-GB typical), this drive
brings performance and manageability to the backup process. The 20/40-GB
DLT Drive requires the DLT IV data cartridge to achieve the 20-GB native
capacity and 40-GB capacity with 2:1 data compression. Yet, the 20/40-GB
DLT is perfect for the 15/30-GB DLT customer to upgrade to because of
the inherent read/write compatibility to the DLT IIIxt data cartridge
used with the 15/30-GB DLT.
Product Highlights
