Rethinking RAID-5 Data Layout for Better Scalability

  title={Rethinking RAID-5 Data Layout for Better Scalability},
  author={Guangyan Zhang and Weimin Zheng and Keqin Li},
  journal={IEEE Transactions on Computers},
In RAID-5, data and parity blocks are distributed across all disks in a round-robin fashion. Previous approaches to RAID-5 scaling preserve such round-robin distribution, therefore requiring all the data to be migrated. In this paper, we rethink RAID-5 data layout and propose a new approach to RAID-5 scaling called MiPiL. First, MiPiL minimizes data migration while maintaining a uniform data distribution, not only for regular data but also for parity data. It moves the minimum number of data… CONTINUE READING
