We present here a report produced by a workshop on 'Addressing failures in exascale
computing'held in Park City, Utah, 4–11 August 2012. The charter of this workshop was to …

Internet Backplane Protocol API and Applications Page 1 SD Codes: Erasure Codes Designed
for How Storage Systems Really Fail James S. Plank University of Tennessee USENIX FAST …

Traditionally, when storage systems employ erasure codes, they are designed to tolerate the
failures of entire disks. However, the most common types of failures are latent sector failures …

Latent sector errors (LSEs) in disk drives cause significant outages, data loss, and
unreliability in large-scale cloud storage systems. Predicting LSEs can help avoid these …

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 …

Scientific applications generate large volumes of data that often needs to be moved between
geographically distributed sites for collaboration or backup which has led to a significant …

Software preservation has not had detailed consideration as a research topic or in practical
application. In this report, we first discuss some of the motivations and problems of software …

For years, discussions of digital preservation have routinely featured comments such as “bit
preservation is a solved problem; the real issues are...”. Indeed, current digital storage …

End-to-end integrity verification is designed to protect file transfers against silent data
corruption by comparing checksum of files at source and destination end points using …

Despite the reliability of modern disks, recent studies have made it clear that a new class of
faults, UndetectedDisk Errors (UDEs) also known as silent data corruption events, become a …
