A non-proprietary RAID replacement for long term preservation systems |
We developed a RAID-free storage system that is able to replace RAID as a fundamental building block. The approach named NRN (No-RAID-Necessary) distributes a configurable number instances of data over a number of drives. To experience data loss all disks which hold an instance of a file have to fail. Even in this case only the data on those disks is lost. The data on the other discs is still accessible.
