The Coming Wave of Declustered RAID

In this podcast, the Radio Free HPC team looks at the coming wave of declustered RAID solutions designed to address the problem of ever-increasing RAID rebuild times. With 5 Terabyte drives in the wings, RAID cluster rebuild times are becoming impractical.

Dan is impressed with what IBM is doing in this area with GPFS.
Henry thinks these larger drives harken the death of RAID-5 and RAID-6.
Rich has been keeping a close watch on Xyratex and their ClusterStor GridRaid implementation.
Read the original paper on Declustered RAID by Garth Gibson and Mark Holland.
