"I/O parallelism"

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 …

Solid-state drives (SSDs) have been widely deployed in large-scale storage systems. To guarantee high reliability for SSD-based storage systems, it still requires data redundancy schemes, e.g., RAID schemes. Traditional RAID-5 shows its benefits in …
