Cloud storage systems are now mature enough to handle a massive volume of
heterogeneous and rapidly changing data, which is known as Big Data. However, failures …

Windows Azure Storage (WAS) is a cloud storage system that provides customers the ability
to store seemingly limitless amounts of data for any duration of time. WAS customers have …

To reduce storage overhead, cloud file systems are transitioning from replication to erasure
codes. This process has revealed new dimensions on which to evaluate the performance of …

We design flexible schemes to explore the tradeoffs between storage space and access
efficiency in reliable data storage systems. Aiming at this goal, two new classes of erasure …

Over the past five years, large-scale storage installations have required fault-protection
beyond RAID-5, leading to a flurry of research on and development of erasure codes for …

This paper descibes version 2.0 of jerasure, a library in C++ that supports erasure coding in
storage applications. In this paper, we describe both the techniques and algorithms, plus the …

A family of codes with a natural 2-D structure is presented, inspired by an application of
redundant arrays of independent disks (RAID) type of architectures whose units are solid …

Latent sector errors (LSEs) refer to the situation where particular sectors on a drive become
inaccessible. LSEs are a critical factor in data reliability, since a single LSE can lead to data …

Modern storage systems use thousands of inexpensive disks to meet the storage
requirement of applications. To enhance the data availability, some form of redundancy is …

Effortless data storage “in the cloud” is gaining popularity for personal, enterprise and
institutional data backups and synchronisation as well as for highly scalable access from …
