Silent Brick Library

FAST LTA revolutionizes the disk library

The Silent Brick Library consists of highly scalable hard disk arrays to give you a Cold Storage system that secures data in the most energy saving and cost efficient way.

Data is stored in dedicated areas based on a linear data structure. You‘ll always know which Silent Brick holds your data – and which one doesn‘t.

The highlight of the system: Each Silent Brick storage container is removable, it holds the complete set of redundancies and will only be powered up when needed.
Energy saving at its best.


Don‘t compromise on security

Silent Bricks are based on the very same FAST LTA Erasure Coding technology with up to 4 redundancy levels that has been proven in thousands of installations. Data is scanned regularly with a Digital Audit and rebuild procedure. No bit will ever be lost.
