Abstract: Modern storage systems adopt erasure coding to maintain fault tolerance with low storage redundancy. However, how to improve the performance of degraded reads in erasure-coded storage has been a critical issue. We revisit this problem… read more here.

DOI: 10.1109/tpds.2020.2983411
Abstract: Erasure codes have been used extensively in large-scale storage systems to reduce the storage overhead of triplication-based storage systems. One key performance issue introduced by erasure codes is the long time needed to recover from… read more here.

DOI: 10.1109/tpds.2022.3152817
Abstract: Erasure coding offers a storage-efficient redundancy mechanism for maintaining data availability guarantees in large-scale storage clusters, yet it also incurs high performance overhead in failure repair. Recent developments in accurate disk failure prediction allow soon-to-fail… read more here.
