ClusterStor GRIDRAID Feature
Benefit
De-clustered RAID 6: Up to 400% faster to repair Rebuild of 6TB drive – MD RAID ~ 33.3 hours, GridRAID ~ 9.5 hours
Recover from a disk failure and return to full data protection faster
Repeal Amdahl’s Law: speed of a parallel system is gated by the performance of the slowest component
Minimizes application impact to widely striped file performance
Minimize file system fragmentation
Improved allocation and layout maximizes sequential data placement
4 to1 Reduction in OSTs
Simplifies scalability challenges
ClusterStor Integrated Management
CLI and GUI configuration, monitoring and management reduces Opex

Economic Benefits of SMR drives SMR Drives Shingled Technology increases capacity of platter by 30-40% › Write tracks are overlapped by up to 50% of write width › Read head is much smaller & can reliably read narrower tracks SMR Drives are optimal for object stores as most data is static/WORM › Updates require special intelligence and may be expensive in terms of performance › “Wide tracks in each band are often reserved for updates CS A200 manages SMR Drives directly to optimize workflow & caching
