Reliability Characterization of Open-Source I/O Caching Modules in Data Storage Systems
, M.Sc. Thesis Sharif University of Technology ; Asadi, Hossein (Supervisor)
Abstract
The performance gap between main memory and storage devices is one of major bottlenecks in data storage systems. I/O caches are one way to reduce this performance gap. In recent years, open source I/O cache modules such as OpenCAS, EnhanceIO, and dm-cache have been examined by researchers from the performance perspective, but the reliability of these modules has not been investigated and compared. In this thesis, we evaluate the reliability of I/O cache modules against hardware failures (e.g., power failure) and software failures (e.g. operating system failure). In addition, we examine the reliability mechanisms in these three modules, whose fault models and their failure rates significantly...

Abstract
In cryptographic engineering, extensive attention has been devoted to ameliorating the performance and security of the algorithms within. Nonetheless, in the state-of-the-art, the approaches for increasing the reliability of the efficient hash functions ECHO and Fugue have not been presented to date.We propose efficient fault detection schemes by presenting closed formulations for the predicted signatures of different transformations in these algorithms. These signatures are derived to achieve low overhead for the specific transformations and can be tailored to include byte/word-wide predicted signatures. Through simulations, we show that the proposed fault detection schemes are...
