TRIP: Temporal Redundancy Integrated Performance Booster for Parity-Based RAID Storage Systems

Abstract

Parity redundancy is widely employed in RAID-structured storage systems to protect against disk failures. However, the small-write problem has been a persistent root cause of the performance bottleneck of such parity-based RAID systems, due to the additional parity update overhead upon each write operation. In this paper, we propose a novel RAID… (More)
