RLS-8350 ​Expandable Rack Mount Library | 1.5 PB to 12.3 PB

Qualstar extends the well-respected RLS Series of automated, high-capacity rack mountable tape libraries with the RLS-8350. Embodying Qualstar’s core values of superior performance, reliability, and value, a single RLS-8350 library module storing uncompressed data on LTO-8 tapes stores up to 600 terabytes of data. Using typical data compression ratios, total capacity can be increased to 1.5 petabytes. Multi-unit configurations support as much as 12.3 petabytes in a single rack.

Expansion Ready
Any RLS-8350 library can be expanded by adding up to three RLS-85120 modules, increasing the total system’s capacity by more than eight times.
