AbstractDr. Tao XieHighly reliable, high performance and energy-efficient storage systems are essential for mobile data-intensive applications such as remote surgery and mobile data center. Existing mobile storage systems generally consist of an array of independent small form factor hard disks connected to a host by a storage interface in a mobile computing environment. Although hard disks are cost-effective and can provide huge capacity and high-throughput, they have some intrinsic limitations such as long access latencies, high annual disk replacement rates, fragile physical characteristics, and energy-inefficiency. Compared with hard disk drives, flash disks are much more robust and energy-efficient, and can offer much faster access times. A major concern on current flash disk is its relatively higher price. This project develops a hybrid disk array system, which integrates small capacity flash disks with high capacity hard disk drives to form a robust and energy-efficient storage system for mobile data-intensive applications. In particular, an array of new data management techniques including energy-efficient data placement, self-adaptive and reliability-aware data redistribution, and self-triggered data replication for data-intensive mobile applications built on the hybrid disk array framework will be developed. In addition, this project implements a simulation toolkit, which will be designed specifically to study a variety of data management techniques on top of the hybrid disk array architecture. This project will also promote teaching, learning, and training by exposing students to technological and scientific underpinnings in the field of energy-efficient storage systems. To enhance education outreach to local underrepresented groups of undergraduate students, this project organizes a summer workshop on energy-efficient computing at San Diego State University.

摘要。 Tao Xiehigherial Corlible，高性能和节能存储系统对于移动数据密集型应用程序（例如远程手术和移动数据中心）至关重要。现有的移动存储系统通常由一个由移动计算环境中的存储界面连接到主机的一系列独立的小型硬盘。尽管硬盘具有成本效益，并且可以提供巨大的容量和高通量，但它们具有一些内在的限制，例如长期访问潜伏期，高年度磁盘替换率，脆弱的物理特性和能量感知性。与硬盘驱动器相比，闪光灯磁盘更加稳健和节能，并且可以提供更快的访问时间。当前闪存磁盘的主要问题是其价格相对较高。该项目开发了一个混合磁盘阵列系统，该系统将小容量闪存磁盘与高容量硬盘驱动器集成在一起，以形成用于移动数据密集型应用程序的强大而节能的存储系统。特别是，将开发一系列新的数据管理技术，包括节能数据放置，自适应和可靠性的数据重新分布以及为基于混合磁盘阵列框架构建的数据密集型移动应用程序的自触发数据复制。此外，该项目实施了模拟工具包，该工具包将专门设计用于在混合磁盘阵列体系结构之上研究各种数据管理技术。该项目还将通过使学生在节能存储系统领域的技术和科学基础上展示教学，学习和培训。为了加强向当地代表性不足的本科生的教育宣传，该项目在圣地亚哥州立大学组织了夏季节能计算的研讨会。
