RAID: End of an era?

Cloud infrastructure imposes new requirements on modern storage systems

Published May 2015

RAID technology has been the fundamental building block for storage systems for many years, providing sufficient flexibility for balancing usable capacity, performance, and redundancy up to now. However, over the course of the last years cloud infrastructures have gained a strong momentum and are imposing new requirements on storage and challenging traditional RAID-based storage systems.

This white paper explains current trends in application development and how this challenges IT operations, the essential ideas about a new open source storage architecture called Ceph, and how Ceph/ETERNUS CD10000 adds new value to OpenStack-based cloud environments in contrast to traditional RAID systems.
