"Declustered RAID" certainly has benefits for recovery of failed disks <br>
but I don't think it claims performance benefits over traditional RAID.<br>
GNR certainly has a large memory footprint. Object RAID is a close <br>
cousin that has flexbile expansion capability, depending on product <br>
packaging GNR could likely match these features.<br>
Argonne labs (Illinois USA) has done a lot with both GNR and RAID GPFS, <br>
I would be interested in their experiences.<br>
