Cold Storage.

Archive data available.

Without tapes.



Your data are most important for current and future applications. Data loss must be absolutely excluded.

Don’t compromise on safety.


“Cold” data must also be available quickly and always. Active (static) archives are replacing slow linear tape technologies.

Due to hard disk storage and random access always available quickly.

Cost brake.

When we talk about petabytes, every Euro per Gigabyte is important. Large-scale growth and high scalability should not lead to cost explosions.

Affordable to grow, highly scalable – a true alternative to tape.

Cold archives with no immediate availability are a thing of the past.

Storage requirements for archives have fundamentally changed. For a long time now, it has not just been about storage – data must always be available quickly and with random access. Security and control of costs, especially in times of ransomware and rapidly growing data volumes, are of central importance.

Not-so-cold-storage with highest security:

The Silent Brick system

Quadruple security:

12/8 Erasure Coding.

In VTL mode, the data on the Silent Bricks are four-fold protected from loss by 12/8 erasure coding. Up to four data carriers may fail simultaneously without losing data. Through Digital Audit, data carriers are also regularly checked for integrity.

Hard disk storage:

Random Access.

Unlike tapes, access to the data on the Silent Bricks is naturally possible by random access. So no cumbersome “spooling” that with tapes also always means the risk of damage. According to our experience, the lifespan is several decades.

Technological alternative:

Affordable, low maintenance.

When used for 10 years and more, our VTL archives offer similarly low costs as tape libraries – but with significantly less maintenance and more functionality.

Archiving satellite data securely

“We were able to observe significantly shorter waiting times when reading data from the archive compared to the old solution.
Thanks to hard disk-based technology, we can now move away from further, faster copy on hard disks.”
