Mathematical reliability models for energy-efficient parallel disk systems

该项目旨在为容错能量感知并行磁盘系统开发数学可靠性模型。可靠性模型是容错计算机系统设计中的重要工具，用于估计系统的可靠性。在过去的十年中，各种实用的可靠性模型已经建立了磁盘系统。然而，这些模型中的大多数是针对非节能磁盘系统开发的，从而使得难以将现有的可靠性模型应用于节能磁盘。因此，本项目的总体目标是解决建模的可靠性的节能并行磁盘系统，容错和节能技术无缝集成，以节省能源，而不牺牲并行磁盘的可靠性的理论基础。该项目可以通过开发一个可靠性分析建模工具包，伴随着一套新颖的数学能力模型，并行磁盘系统的可靠性建模技术作出贡献。创新的模型包括磁盘功耗模型，一个可靠性模型的并行磁盘系统与冗余技术，可靠性模型的可修复和节能的并行磁盘系统，故障恢复模型的节能并行磁盘系统。这项研究有三个主要优势。首先，它弥合了并行磁盘系统的可靠性分析和节能技术之间的技术差距。其次，研究可以有助于实现一系列的数学可靠性模型的节能并行磁盘系统。最后，本项目创建了一个可靠性分析工具包，这是第一个专门设计用于研究各种容错和节能技术的工具包。

This project aims at developing mathematical reliability models for fault-tolerant energy-aware parallel disk systems. Reliability models, which are used to estimate reliability, are important tools in the design of fault-tolerant computer systems. In the past decade, various practical 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 efficient disks. Therefore, the overall objective of this project is to address the mathemetical underpinnings of modeling reliability of energy-efficient parallel disk systems, where fault tolerance and energy-saving techniques are seamlessly integrated to conserve energy without sacrificing reliability in parallel disks. The project can contribute to reliability modeling techniques for parallel disk systems by developing a reliability analysis modeling toolkit accompanied with a set of novel mathematical ability models. The innovative models 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. This research has three main strengths. First, it bridges the technology gap between reliability analysis and energy conservation techniques in the context of parallel disk systems. Second, the research can contribute to the implementation of an array of mathematical reliability models for energy-efficient parallel disk systems. Finally, this project creates a reliability analysis toolkit, which is the first toolkit of its kind designed specifically to study a variety of fault-tolerant and energy-saving techniques.
