Since its introduction in February, 1996, the Compaq DLT Tape Array (which uses Compaq
15/30 GB DLT drives) has been an industry leader in backup performance capabilities. The
DLT Tape Array II, which uses 35/70 GB DLT drives, sets new standards in high-speed backup
performance.
Early in 1997, Compaq performed a series of tests to examine the performance of the Compaq
35/70 GB DLT drive and the DLT Tape Array II. The objective of these tests was to find the
highest-performance configurations in a variety of backup scenarios on Compaq servers
running Windows NT and Novell IntranetWare network operating systems.
The Compaq DLT Tape Array II provides high-capacity, high-speed tape storage for use in
local and remote backup strategies. It uses the Compaq 35/70 GB DLT drive, which is
engineered for superior performance. This brief addresses the technical aspects of high-
performance backups that can reach and exceed 165 gigabytes per hour (GB/hr) with off-the-
shelf Compaq hardware.
