“…Existing scaling schemes designed for RAIDs include SLAS [26], SCADDAR [47], FastScale [25], McPod [31], ALV [32], MiPiL [33], MDM [28], GA [34], GSR [27], PBM [35], SDM [29], and so on. Data redistribution in scaling RScoded chunk groups consists of data migration and parity update; the data migration can be completed using RAID-0 scaling approaches (e.g., Round-Robin, FastScale, etc.).…”
