标题：使用编码技术的存储系统中的节能该项目探索了存储系统的系统级能源管理方案。它的目标是开发存储组织、分组和数据布局，通过利用系统中已构建的复杂冗余来实现容错，从而促进能源节约。这种方法的动机是在存储系统中使用日益复杂的冗余技术来防止数据丢失的趋势。该项目研究了利用这种冗余来提供附加功能的方法，特别是节能。该项目涉及几个部分：使用复制和擦除编码技术探索设计空间以节约能源；设计用于动态磁盘配置的控制机制和算法以及相关的性能和能量模型；以及开发用于对这些技术进行经验验证的试验台。在大规模存储系统的运行中，能耗已经成为一个越来越重要的问题。电力和冷却设备以及电力占总拥有成本的很大一部分。该项目的结果对大型仓储中心的运营具有潜在的经济和环境影响。

Title: Energy Conservation in Storage Systems Using Coding Techniques The project explores system-level energy management schemes for storage systems. It aims to develop storage organizations, groupings, and data layouts that facilitate energy conservation by exploiting complex redundancy already built into the system for fault tolerance. The approach is motivated by the trend towards using increasingly sophisticated redundancy techniques in storage systems to guard against data loss. The project investigates methods to leverage this redundancy to provide additional functionality, in particular energy conservation. The project involves several components: exploration of the design space using replication as well as erasure-coding techniques for energy conservation, design of control mechanisms and algorithms for dynamic disk provisioning and associated performance and energy models, and development of a test-bed for empirical validation of the techniques. Energy consumption has become an increasingly important issue in the operations of large-scale storage systems. Power and cooling equipment, and electricity together represent a significant portion of the total cost of ownership. The results of this project have potential for economic and environmental impact on the operation of large storage centers.
