This paper presents SafeStore, a distributed storage system designed to maintain long-term
data durability despite conventional hardware and software faults, environmental …

Data reliability and storage costs are two primary concerns for current Cloud storage
systems. To ensure data reliability, the widely used multi-replica (typically three) replication …

Parity is a popular form of data protection in redundant arrays of inexpensive/independent
disks (RAID). RAID5 dedicates one out of N disks to parity to mask single disk failures, that …

With the advent of cloud computing and online services, large enterprises rely heavily on
their data centers to serve end users. Among different server components, hard disk drives …

The increasingly large demand for data storage has spurred on the development of systems
that rely on the aggregate performance of multiple hard drives. In many of these …

Data reliability is paramount in modern storage systems. Such reliability is generally
provided using erasure codes across storage devices. Until recently, most systems …

The booming of cloud computing, online services and big data applications have resulted in
dramatic expansion of storage systems. Meanwhile, disk drives are reported to be the most …

Weibull distributions can be used to accurately model failure behaviours of a wide range of
critical systems such as on-orbit satellite subsystems. Markov chains have been used …

Existing power-aware optimization schemes for disk-array systems tend to strike a delicate
balance between energy consumption and performance while ignoring reliability. To …

Archival storage systems are designed for a write-once, read-maybe usage model which
places an emphasis on the long-term preservation of their data contents. In contrast to …
