Q48 Mid-Range LTO Tape Library | Over a Petabyte of Data in a 4U Enclosure

Easy installation and easy maintenance are two important features of the Q48 mid-range LTO tape library, which is designed to be simply reliable. Housed in a rack mountable 4U enclosure, the Q48 offers capacities up to 864 terabytes (native) and 16 petabytes (compressed). The menu-driven graphical built-in operator control panel is easy to use, and the identical functionality may also be accessed via the integrated browser-based remote management interface (RMI). This enables IT administrators to remotely configure, manage and diagnose the library from anywhere in the world via the Internet. All field replaceable components, such as the tape drives, power supply and controller board are removable with standard tools. The Qualstar Q48 data storage capacity can be expanded by upgrading to newer generation LTO technology.

This product is not currently available for use in the EU.
