Tape Libraries by Qualstar

Qualstar has been creating reliable, cost effective and simple to use automated tape libraries for decades. Our tape libraries can typically house multiple drives and from 10 to 100's of tapes. With the high availability of low cost, high density cartridge tape formats such as Sony AIT and Ultrium Linear Tape Open (LTO), tape backup and archival has stood the test of time as an efficient and cost effective method of backup, data protection and archival.

Qualstar Innovations Improving
Reliability & Performance
  • 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
  • Compass Architecture
  • Support for industry ieading software and operating sysetems

There are over twenty tape library models providing combinations of capacity and throughput to match any storage management requirement. At the enterprise level, our libraries house up to 96 tape drives and 6000 cartridges, and store multiple PetaBytes of data.

An optional Fibre Channel interface option provides SAN correction for library command and control. Direct Fiber Attach (DFA) tape drives are also now available in some formats.

Qualstar tape libraries are designed for continuous, unattended operation and allow simultaneous reading and writing to multiple drives. They 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. Typically they come in either a free-standing tape library enclosure, or as a rack mount option.

Full Remote Tape & Data Management
All TLS and RLS tape libraries contain Q-Link Remote Library Manager, and our XLS series contain our X-Link Remote Library Manager. These are our web browser based remote library managers 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 and X-Link extend 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.

Eco-friendly Solutions
Qualstar's N2Power subsidiary has pioneered and patented hi-efficiency power technology for years. Storing data in our tape libraries uses much less power than disk, saving money by substantially reducing electrical and cooling requirements. See our case study Green vs Green for more.
