Mass capacity on HP's DDS-3 DAT

Mass capacity on HP's DDS-3 DAT

Small- to-medium-size enterprise servers and networks may be ideal targets for HP's new 24Gb DAT drive, based on the new Digital Data Storage-3 (DDS-3) format. The drive "effectively offers three times the capacity and double the data-transfer rates of current DDS-2 drives", claims exclusive distributor, Lynx Technologies Australia.

The new drive is priced substantially lower than 8mm or digital linear tape products with similar capacities.

It stores 24Gb of data on a single 125m tape at a rate of 2Mb/sec using built-in hardware compression.

Its jump in capacity and performance is attributed to an increased data density on DDS-3 media which in turn is made possible by an optimisation of the head-tape interface.

Incorporated in the new drive is the use of a partial response maximum likelihood (PRML) data-channel detection scheme that allows the tape's read head to differentiate between data bits picked up simultaneously and improves a product's internal data transfer rates.

To support its claims for high reliability, HP gives it a 300,000 hour MTBF rating, Read-After-Write data verification and a new intelligent error-recovery feature.

In addition the DDS-3 drive offers full read and write compatibility with all DDS-2 and DDS drives.

Additional features of the DDS-3 include "fast-search" which finds files in an average of 40 seconds; and advanced head cleaning which automatically minimises and sweeps away the accumulation of dirt and media debris at the head/tape interface.

This latter facility protects users' data from errors attributed to contamination.

Wide support

Supported platforms for DDS-3 include NetWare 3.x and 4.x; Windows NT; OS/2; Windows 3.x and 95; SCO Unix; HP-UX; IBM AIX; Sun OS/Solaris; Silicon Graphics IRIX; DEC OSF/1; and UnixWare.

The retail price of the HP C1554A DDS-3 drive is $2500 and it is available to dealers through Lynx Technologies Australia, which also provides technical advice, pre-sales consulting and after-sales service.
