The ever-increasing demand of storage capability leads to scaling requirement in RAID-structured storage systems. Previous approaches to RAID scaling mainly focus on minimizing data migration, without considering the user-level application accesses. …
RAID provides a good option to provide device-level fault tolerance. Conventional RAID usually updates parities with read-modify-write or read-reconstruct-write, which may introduce a lot of extra I/Os and thus significantly degrade SSD RAID …
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 …
Solid-state drives (SSDs) have been widely deployed in desktops and data centers. However, SSDs suffer from bit errors, and the bit error rate is time dependent since it increases as an SSD wears down. Traditional storage systems mainly use …
