Operating Time before Required MaintenanceYears between MaintenanceCompute BrickStorage BrickFailure Rate per YearNote: 4% “storage” brick failure rate is 2% for disks plus 2% for electronicsARC External Website, Intelligent Bricks, 2005
Reliability via “Distributed RAID”• Failed disk/brick’s data are rebuilt across all bricks, utilizing sparecapacity• For an extreme target of 0.5 failures per ExaByte-year (1 data lossevent in 5 years in 25,000 100-disk systems), KK Rao & Jim Hafner@ARC have recommended a choice of 3-failure-tolerant, distance-4redundancy codes:• 1-failure-tolerant (RAID5) in bricks and 2-failure-tolerant (“Dist 3”)code between bricks– 40 - 75 % storage efficiencyOR• 0-failure-tolerant (NoRAID) in bricks and 3-failure-tolerant (“Dist 4”)code between bricks– 50 - 75 % storage efficiencyARC External Website, Intelligent Bricks, 2005
