ATL Design Philosophy: Keeping You Out of the Exposure Zone
Many products are
introduced with reliability
specifications that are not
proven. The result is
customers are exposed to
lower reliability than the
productÕs specified rating.
ATL keeps you out of the
exposure zone by
adhering to a strict
regimen of tests. The
process builds a high
degree of confidence that
ATLÕs products meet their
specified reliability before
entering the market.
Elements of a
Reliable Tape Library
Customer surveys reveal that reliability is the most important buying decision when considering a tape
library. ATLÕs testing has shown there are three key elements that significantly contribute to library
reliability:
1. Precision Cartridge Handling
Tape cartridges are sensitive to the accuracy of cartridge load and unload operations. The angle
of approach upon cartridge insertion and the timing of tape removal during cartridge ejection are
critical control elements that are accounted for by ATLÕs patented IntelliGrip cartridge handling
system. In addition, IntelliGrip assures data accessibility by eliminating the need for tape feeder
mechanisms that slide cartridges across metal or plastic surfaces, causing debris buildup in the
tape drive that in turn degrades performance.
2. Maintaining Alignment
Misalignment of cartridges, drives and robotic mechanisms can be caused by shock, operating
vibration and temperature changes common within a library environment. To maintain the
precision alignment required of tape automation, P2000 Series libraries feature ATLÕs Automatic
Self-Alignment, which assures error-free cartridge handling. In addition, the P2000 libraries are
enclosed in a Welded Frame (not spot welded like other manufacturers) to provide a solid base
for the entire library, eliminating the potential for frame movement.
3. Quality Manufacturing Process
The best design in the world will fail if the assembly process is flawed. ATL implements an
extensive quality assurance and burn-in process to eliminate assembly errors. ATL also addresses
another common problem: tape drive failures. Through ATLÕs design and rigorous drive screening
process, the company has achieved field reliability three times greater than the drive
manufacturer's specified rating.
Confidence Improves with Learning Events (Primarily Tests), Not with Time.
