In a distributed storage system, code symbols are dispersed across space in nodes or
storage units as opposed to time. In settings such as that of a large data center, an important …

Large distributed storage systems use erasure codes to reliably store data. Compared to
replication, erasure codes are capable of reducing storage overhead. However, repairing …

Erasure codes are being extensively deployed in distributed storage systems instead of
replication to achieve fault tolerance in a storage efficient manner. While traditional erasure …

As data in modern cloud storage system grows dramatically, it's a common method to
partition data and store them in different Availability Zones (AZs). Multiple AZs not only …

The traditional means of ensuring reliability in data storage is to store multiple copies of the
same file in different storage units. Such a replication strategy is clearly inefficient in terms of …

Erasure codes in large-scale storage systems allow recovery of data from a failed node. A
recently developed class of codes, locally repairable codes (LRCs), offers tradeoffs between …

Consider a binary maximum distance separable (MDS) array code composed of an mx (k+ r)
array of bits with k information columns and r parity columns, such that any k out of k+ r …

Erasure coding is widely used in building reliable distributed object storage systems despite
its high repair cost. Regenerating codes are a special class of erasure codes, which are …

As storage systems grow in size, device failures happen more frequently than ever before.
Given the commodity nature of hard drives employed, a storage system needs to tolerate a …

Binary maximum distance separable (MDS) array codes are a special class of erasure
codes for distributed storage that not only provides fault tolerance with minimum storage …
