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.

AbstractDr。高可靠、高性能、高能效的存储系统对于远程手术、移动数据中心等移动数据密集型应用至关重要。现有的移动存储系统通常由一组独立的小尺寸硬盘组成，通过移动计算环境中的存储接口连接到主机。尽管硬盘具有成本效益，并且可以提供大容量和高吞吐量，但它们具有一些固有的局限性，例如访问延迟长、每年磁盘更换率高、物理特性脆弱以及能源效率低。与硬盘驱动器相比，闪存驱动器更加坚固和节能，并且可以提供更快的访问时间。目前闪存盘的一个主要问题是其相对较高的价格。本项目开发一种混合磁盘阵列系统，将小容量闪存盘与大容量硬盘驱动器集成在一起，形成一个健壮、节能的移动数据密集型应用存储系统。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，自适应和可靠性感知数据重新分配，以及基于混合磁盘阵列框架的数据密集型移动应用程序的自触发数据复制。此外，该项目还实现了一个仿真工具包，该工具包将专门用于研究混合磁盘阵列架构之上的各种数据管理技术。该项目还将通过让学生接触节能存储系统领域的技术和科学基础，促进教学、学习和培训。为了加强对当地代表性不足的本科生群体的教育推广，该项目在圣地亚哥州立大学组织了一个关于节能计算的夏季讲习班。
