Automated tape handling
has been prevalent in mainframe computer centers for over 20
years. The benefits of this technology are now widely
available to users of low cost, high density cartridge tape
formats.
Tape automation products are generally
divided into two groups: autoloaders and libraries.
Autoloaders hold 1 tape drive and a limited number of
cartridges, typically 8 to 16, although some will house over
20. Autoloaders are limited in both capacity and throughput.
They are primarily intended to support small department or
single application backups.
Qualstar XLS, TLS and
RLS Series Tape Library Systems
XLS Sets New Standards
in the Four Critical Areas of Enterprise Data Storage
-
Maximum Density: XLS conserves valuable IT floor space by using
Qualstar's trademark rotary carousel design
-
Revolutionary Performance:
Compass Architecture, Qualstar's revolutionary
short-travel robotic design, insures fast access to
large amounts of data without sacrificing reliability
-
Balanced Economy: XLS allows you to balance
capacity and performance to fit your current requirements and protect your investment as needs grow
-
Unlimited Scalability: The
unique flexibility of XLS' modular design scales
seamlessly from 350 tapes to over 9,600 tapes
Tape libraries invariably house 2 or more
drives and from 10 to 100's of tapes. Libraries are designed
for continuous, unattended operation and allow simultaneous
reading and writing to multiple drives. Libraries also offer
key features such as barcode readers to scan labels on
cartridges, and an I/O Port for importing and exporting
individual tapes under application control. A Fibre Channel
Option makes any model a Qualstar SANSmart library. DFA
(Direct Fiber Attach) tape drives are also now available in
some formats. An iSCSI option connects RLS and TLS Libraries
to IP SANS.
AIT, SuperAIT and LTO Tape
Formats
Qualstar designs and manufactures libraries
for the popular AIT, SuperAIT and LTO tape
formats, housing up to 12 tape drives and 600 cartridges.
Barcode support is standard in most models and I/O Ports are
available. Over twenty-five models provide combinations of
capacity and throughput to match any storage management
requirement.
Our latest RLS-Series rackmount libraries
set the industry standard for capacity in compact 5U
packages. Qualstar libraries are compatible with virtually
all back-up software manufacturers, providing a full range
of backup, data protection, business continuity and
archival.
All Qualstar libraries are available with
Q-Link, our web browser based remote library manager that
enables administrators to configure, upgrade, and monitor
any of our libraries via a company intranet or over the
Internet from anywhere in the world. Q-Link extends the
library's comprehensive front panel menu system and adds
additional functionality such as automatic e-mail
notification based on rules set by the administrator, and
remotely implemented firmware updates.
Our TLS and RLS Series libraries
incorporate a number of innovations that improve reliability
and performance, including:
- Inventory Sentry to allow the library
to be opened to read handwritten cartridge labels
without forcing the unit off-line for an unnecessary
inventory of all cartridges
- Closed loop servo control of all
motions for absolute position accuracy
- Leadscrew-driven mechanisms for highest
reliability, instead of belts and pulleys
