By 2011, data centers in the U.S. are poised to consume around 100 billion KW of energy, half of which in servers. The majority of power consumption will shift from the processor to main memory. This project, rather than relying solely on DRAM, uses multiple technologies to construct a high-capacity, energy-efficient memory system for virtualized computer servers with a new Storage Class Memory Architecture that incorporates multiple memory technologies such as DRAM, Phase-change memory (PRAM) and Flash.This project is ambitious with fundamental and applied contributions in the design and development of energy-efficient computer servers. The fundamental contributions include: a new integrated memory architecture that seamlessly manages hybrid memory resources; novel algorithms and policies for energy, performance and endurance management; better understanding of the hypervisor?s role in resource management and its interaction with upper and lower system layers; and a new hybrid DRAM and PRAM main memory controller. The applied contribution is in the form of tools that will be developed and disseminate, including simulations, analytic models and actual software/emulated hardware system. This research represents a new "green computing technology" that satisfies the demands of future computing systems (e.g., cloud computing, server farms, commodity computers) in an exceptionally low energy manner. The project impacts undergraduate and graduate students through research opportunities and industry internships and aims to recruit people from under-represented groups in computer science and computer engineering.

到 2011 年，美国数据中心预计将消耗约 1000 亿千瓦的能源，其中一半用于服务器。大部分功耗将从处理器转移到主存储器。 该项目并非单纯依赖DRAM，而是采用多种技术，采用新型存储级内存架构，融合了DRAM、相变内存（ PRAM）和闪存。该项目雄心勃勃，在节能计算机服务器的设计和开发方面做出了基础和应用贡献。基本贡献包括：新的集成内存架构，可无缝管理混合内存资源；用于能量、性能和耐力管理的新颖算法和策略；更好地理解虚拟机管理程序在资源管理中的作用及其与上下系统层的交互；以及新型 DRAM 和 PRAM 混合主存控制器。应用贡献将以将要开发和传播的工具的形式出现，包括模拟、分析模型和实际软件/模拟硬件系统。这项研究代表了一种新的“绿色计算技术”，它以极低能耗的方式满足未来计算系统（例如云计算、服务器场、商用计算机）的需求。该项目通过研究机会和行业实习影响本科生和研究生，旨在从计算机科学和计算机工程领域的代表性不足群体中招募人员。
