A Flexible and Low-Complexity Local Erasure Recovery Scheme

Abstract: A flexible yet low-complexity local erasure coding scheme for failure recovery is presented in this work. Although the proposed scheme is not maximum distance separable, it does not have much constraint on the locality or the parameters of the code, allows easy tradeoff on the locality and redundancy, and can achieve unequal protection over drives with different reliabilities. More importantly, it can be implemented with low hardware complexity.
