Request Bridging and Interleaving: Improving the Performance of Small Synchronous Updates under Seek-Optimizing Disk Subsystems
Dong In Shin, Young Jin Yu, Hyeong S. Kim, Hyeonsang Eom, Heon Young Yeom
Article No.: 4
DOI: 10.1145/1970348.1970349

Write-through caching in modern disk drives enables the protection of data in the event of power failures as well as from certain disk errors when the write-back cache does not. Host system can achieve these benefits at the price of significant...

Disk Scrubbing Versus Intradisk Redundancy for RAID Storage Systems
Ilias Iliadis, Robert Haas, Xiao-Yu Hu, Evangelos Eleftheriou
Article No.: 5
DOI: 10.1145/1970348.1970350

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, disk scrubbing scheme, which operates by periodically accessing disk...

PRESIDIO: A Framework for Efficient Archival Data Storage
Lawrence L. You, Kristal T. Pollack, Darrell D. E. Long, K. Gopinath
Article No.: 6
DOI: 10.1145/1970348.1970351

The ever-increasing volume of archival data that needs to be reliably retained for long periods of time and the decreasing costs of disk storage, memory, and processing have motivated the design of low-cost, high-efficiency disk-based storage...
