A new intra-disk redundancy scheme for high-reliability RAID storage systems in the presence of unrecoverable errors
Ajay Dholakia, Evangelos Eleftheriou, Xiao-Yu Hu, Ilias Iliadis, Jai Menon, K.K. Rao
Article No.: 1
DOI: 10.1145/1353452.1353453

Today's data storage systems are increasingly adopting low-cost disk drives that have higher capacity but lower reliability, leading to more frequent rebuilds and to a higher risk of unrecoverable media errors. We propose an efficient intradisk...

Predictive data grouping: Defining the bounds of energy and latency reduction through predictive data grouping and replication
David Essary, Ahmed Amer
Article No.: 2
DOI: 10.1145/1353452.1353454

We demonstrate that predictive grouping is an effective mechanism for reducing disk arm movement, thereby simultaneously reducing energy consumption and data access latency. We further demonstrate that predictive grouping has untapped dramatic...

A new approach to dynamic self-tuning of database buffers
Dinh Nguyen Tran, Phung Chinh Huynh, Y. C. Tay, Anthony K. H. Tung
Article No.: 3
DOI: 10.1145/1353452.1353455

Current businesses rely heavily on efficient access to their databases. Manual tuning of these database systems by performance experts is increasingly infeasible: For small companies, hiring an expert may be too expensive; for large enterprises,...
