Parity declustering for continuous operation in redundant disk arrays
1992
Proceedings of the fifth international conference on Architectural support for programming languages and operating systems - ASPLOS-V
We describe and evaluate a strategy for declustering the parity encoding in a redundant disk array. This declustered parity organization balances cost against data reliability and performance during failure recovery in highly-available parity-based arrays for use in continuous-operation systems. It improves on standard parity organizations by reducing the additional load on surviving disks during the reconstruction of a failed disk's contents. This yields higher user throughput during recovery,
