MINT: Mathematical Reliability Models for Energy-Efficient Parallel Disk Systems

Final Report

Our Mission:

The MINT project aims at developing mathematical reliability models for fault-tolerant energy-aware disk systems. Reliability models, which are used to estimate reliability, have been important tools in the design and development of fault-tolerant computer systems. In the past decade, a variety of practical and useful reliability models have been constructed for disk systems. However, most of these models were developed for non-energy efficient disk systems, thereby making it difficult to apply the existing reliability models to energy-aware disk systems. Therefore, the overall objective of this project is to address the mathematical underpinnings of modeling reliability of energy-efficient parallel disk systems, where fault tolerance and energy-saving techniques will be seamlessly integrated together to conserve energy without sacrificing reliability in parallel disk systems.

Our Approach:

The project will contribute to reliability modeling techniques for fault-tolerant and energy-efficient parallel disk systems by developing a reliability analysis modeling toolkit accompanied with a set of novel mathematical reliability models. The innovative models investigated in this project include disk power consumption models, a reliability model for parallel disk systems with redundancy techniques, a reliability model for repairable and energy-efficient parallel disk systems, a fault recovery model for energy-efficient parallel disk systems. The proposed research has three main strengths. First, we bridge the technology gap between reliability analysis and energy conservation techniques in the context of parallel disk systems. Second, we seek to develop an array of mathematical reliability models for energy-efficient parallel disk systems. Finally, we will implement a reliability analysis toolkit, which will be the first toolkit of its kind designed specifically to study a variety of fault-tolerant and energy-saving techniques.

Research Project: Reliability Models of Energy-Efficient Parallel Disk Systems with Data Mirroring.
In this project we make use of a Markov process to develop a quantitative reliability model for energy-efficient parallel disk systems with data mirroring. With the new models in place, a reliability analysis tool is developed to efficiently evaluate reliability of fault-tolerant parallel disk systems with multiple power states.
