Qualstar Tape Libraries

Qualstar has been creating reliable, cost effective and easy to use automated tape libraries for over fifteen years. With low cost, high density Ultrium Linear Tape Open (LTO), tape libraries are clearly the most efficient and cost effective storage for backup, data protection and archiving.


RLS8350Offering superior performance and value, the RLS-8350 delivers 125 terabytes (native) on either LTO 5 (1.5TB) or LTO 6 (2.5TB) tapes.

Libraries can be partitioned, for more than one physical library.

Up to three drives can be installed in the base system with further expansion possible through additional modules:
