Parity Redundancy Strategies in a Large Scale Distributed Storage System.
John A. Chandy · 2004
With the deployment of larger and larger distributed storage systems, data reliability becomes more and more of a concern. In particular, redundancy techniques that may have been appropriate in small-scale storage systems and disk arrays may not be sufficient when applied to larger scale systems. We propose a new mechanism called delayed parity generation with active data replication (DPGADR) to maintain high reliability in a large scale distributed storage system without sacrificing fault-free performance. 1
