Built with maximum flexibility at its core, the all-new Spectra Stack Tape Library from Spectra Logic will meet your backup, archive and perpetual storage requirements. Designed to be easily installed, expanded and managed, the Spectra Stack is rated at a 100% duty cycle – meaning it is one of the only stackable libraries built to perform in a 24/7 environment. Spectra Stack starts as a 6U library with 1 to 6 LTO tape drives and 10 to 80 LTO tape slots. Each module of the Spectra Stack holds an additional 10 to 80 tape slots and 1 to 6 tape drives. Scalable from 10 to 560 tape slots and 1 to 42 tape drives, users can store more than 6.7PB (16.7PB compressed*) of data in a fully expanded Spectra Stack library. This extreme flexibility provides affordability and expandability without compromise.
