L20 Tape Library


     For more information :


The L20 is the first in the L20/L40/L80 series of tape libraries that deliver asset protection and management to distributed NT, Novell, Linux and UNIX environments.

  • Easy to Use. Easy to follow installation instructions and configuration set-up from your workstation allows you to install and configure the L20 quickly and efficiently.

  • Worry Free Data Protection. In addition to the fundamental functions of backup, archiving and data interchange, you get peace of mind from knowing that automated backups occur on a regular basis eliminating human error.

  • Simplified Administration. Remote monitoring and management tools allow you to offload administration tasks to a single, centralized location. You can also use your existing system management tools or take advantage of convenient Web-based monitoring.

  • More Control for Less Money. Because tape costs significantly less than disk, tape automation allows you to supplement disk mirroring and enhance your storage strategy within a limited budget.

  • Ease of Upgrade. Extend storage by upgrading to a larger capacity library system as your needs grow. No on-site assembly or sophisticated training required. The upgrade is just as simple as your initial library installation by simply swapping the smaller unit for a larger one.

  • Flexible Platform. Supports multiple tape drive technologies, including LTO Generation 1 and 2, SDLT 220 and 320, DLT 8000.

  • Easy upgrade to fibre channel.
