Nowadays many clustered file systems adopt asynchronous encoding which transforms replicated data into erasure coding to maintain data availability with bounded storage overhead. Existing implementations of asynchronous encoding construct coding …
Distributed storage systems provide large-scale data storage services, yet they are confronted with frequent node failures. To ensure data availability, a storage system often introduces data redundancy via replication or erasure coding. As erasure …
Modern distributed storage systems often deploy deduplication to remove content-level redundancy and hence improve storage efficiency. However, deduplication inevitably leads to unbalanced data placement across storage nodes, thereby degrading read …
