Traditional RAID Solutions do have the disadvantage of long rebuild times, sometimes several days for large file systems. During this time all volumes in a RAID group are affected by performance degradation.

One E5400 NetApp system attached to our FDR test cluster will be used to evaluate the new features of DDP.
