Emulating goliath storage systems with David
Nitin Agrawal, Leo Arulraj, Andrea C. Arpaci-Dusseau, Remzi H. Arpaci-Dusseau
Article No.: 12
DOI: 10.1145/2078861.2078862

Benchmarking file and storage systems on large file-system images is important, but difficult and often infeasible. Typically, running benchmarks on such large disk setups is a frequent source of frustration for file-system evaluators; the...

Making the common case the only case with anticipatory memory allocation
Swaminathan Sundararaman, Yupu Zhang, Sriram Subramanian, Andrea C. Arpaci-Dusseau, Remzi H. Arpaci-Dusseau
Article No.: 13
DOI: 10.1145/2078861.2078863

We present anticipatory memory allocation (AMA), a new method to build kernel code that is robust to memory-allocation failures. AMA avoids the usual difficulties in handling allocation failures through a novel combination of static and...

A study of practical deduplication
Dutch T. Meyer, William J. Bolosky
Article No.: 14
DOI: 10.1145/2078861.2078864

We collected file system content data from 857 desktop computers at Microsoft over a span of 4 weeks. We analyzed the data to determine the relative efficacy of data deduplication, particularly considering whole-file versus block-level elimination...
