The Case for Active Block Layer Extensions ∗
- …Self-managing storage systems have recently received attention from the research community due to their promised ability of continuously adapting to best reflect high-level system goal specifications. However, this eventuality is currently being met by both conceptual and practical challenges that t…

UPGRAID: Usage-base striPe replicatinG RAID
- …the standard for large scale, fault-tolerant storage solutions. The various RAID levels combine space and/or performance optimization to meet the needs of the user. In the paper we introduce UPGRAID, which can be seen as a new RAID level built upon RAID5. The idea behind UPGRAID is that, by allocati…

1 EXCES: EXternal Caching in Energy Saving Storage Systems
- …Abstract: Power consumption within the disk-based storage subsystem forms a substantial portion of the overall energy footprint in commodity systems. Researchers have proposed external caching on a persistent, low-power storage device which we term external caching device (ECD), to minimize disk act…

BORG: Block-reORGanization and Self-optimization in Storage Systems
- …Disk I/O is the primary performance bottleneck for a wide range of workloads due to the relatively large, mechanical seek and rotational delay overheads incurred during I/O operations. Current-day file systems that exclusively manage storage space on disk drives employ static data layouts and do not…
