All previous multicopy algorithms require additional space for redundant information equal to the size of the object being replicated. This paper proposes a new multicopy algorith...
Two schemes proposed to cope with unrecoverable or latent media errors and enhance the reliability of RAID systems are examined. The first scheme is the established, widely used d...

In this paper, a simple codec algorithm based on Reed-Solomon (RS) codes is proposed for erasure correcting in RAID (Redundant Array of Independent Disks) level 6 systems. Unlike ...
The RAID-6 specification calls for a storage system with multiple storage devices to tolerate the failure of any two devices. Numerous erasure coding techniques have been develope...
Previous approaches to RAID scaling either require a very large amount of data to be migrated, or cannot tolerate multiple disk additions without resulting in disk imbalance. In t...
