Qualstar Libraries

The RLS series rackmount tape libraries deliver all the speed, capacity and reliability you’ve come to expect from Qualstar–all within a compact, space-saving 5U rack enclosure.

With support for AIT, SAIT, LTO and SDLT tape drive formats, the complete RLS series consists of 7 models offering capacities up to 57 terabytes (compressed). Need speed? How about the RLS series’ blazing transfer speed of up to 561 gigabytes per hour?

High Availability Features
To reduce downtime, a number of high availability options have been included in Qualstar’s RLS series rackmount tape libraries, such as:

Upgradability = Investment Protection
All of Qualstar’s rackmount tape libraries feature IPM (Interface Personality Module) architecture. By simply plugging in the appropriate IPM, the unit(s) can be reconfigured in a matter of seconds for SCSI, Fibre Channel, iSCSI or future interface architectures. In addition, a field capacity expansion kit is available to economically upgrade the RLS-4445 to an RLS-4470.

Reliable, Intelligent Robotics
Unique, leadscrew-based robotics use brushless DC motors and closed-loop servo control systems to provide precise media positioning and flawless handling for years of dependable operation. All FRU’s (Field Replaceable Units) and tape drives are auto-discovering, and all electrical and mechanical adjustments have been completely eliminated by sophisticated adaptive ‘smart’ logic design.

Easy, Intuitive Operation
All rackmount tape libraries feature an onboard LCD panel (shown right) that provides an intuitive, easy-to-use, menu-driven control system for accessing installation, configuration, and operational information. Critical operating functions are displayed and an audible alarm signals conditions requiring immediate action. All of the information, functions and controls built into the front panel display are replicated in Q-Link, the powerful, Web-browser-based remote library manager.

Advanced Cartridge Management and Security
Bar code scanning enhances throughput and controls the media inventory. VIOP, a unique variable I/O port design, allows users to determine how many slots to commit to importing and exporting tapes. Qualstar’s exclusive ‘Inventory Sentry’ senses whether the tapes or magazines have actually been removed when the door is opened. If they haven’t, operation is resumed without causing a time consuming re-inventory.

Logical Library and Fibre Channel
Logical Library is built into all RLS series rackmount tape libraries. This allows up to four servers to share a single library, even if each server is running a separate application. Systems that you couldn’t previously afford to upgrade can now be protected automatically.
