SBIR Phase II: Intelligent Software Power Management for Windows-based Systems

这个小型企业创新研究（SBIR）第二阶段项目将开发和商业化智能软件电源管理数据中心解决方案。 当前的默认电源管理在某些负载下会严重降低服务器性能，最高可达40%。因此，默认电源管理目前没有部署，数据中心中的大多数服务器正在浪费大量能源。建议的产品鼓励用户启用独特的电源管理功能，在正常负载下节省高达35%的能源。该方法允许用户设置预期的服务级别，并限制电源管理对服务器性能的影响。例如，用户可以设置10%的性能损失策略，软件将在不违反策略的情况下尽可能多地节省能源。数据中心运营商需要在数据中心中使用节能服务器。美国和国外的数据中心为互联网和电子商务提供了技术支柱。截至2005年，数据中心占美国能源消耗总量的2%。数据中心管理人员认为功耗是他们目前最关心的问题，因为：1）运行服务器的能源成本现在通常高于采购成本; 2）过度使用能源会产生热量，降低系统可靠性。 如果成功部署，拟议的方法有可能解决新兴市场的痛点，并产生重大的积极经济影响。

This Small Business Innovation Research (SBIR) Phase II project will develop and commercialize an intelligent software power management data center solution. The current default power management can seriously degrade server performance as much as 40% under certain loads. As a result, the default power management is currently not deployed and most servers in the data center are wasting significant energy. The proposed product encourages users to enable the unique power management capabilities to save up to 35% energy under normal load. The approach allows users to set the expected service-level and bound the impact of power management on server performance. For example, users can set a policy of 10% performance loss and the software will save as much energy as possible without violating the policy. Data center operators require energy efficient servers in the data center. Data centers in the U.S. and abroad provide the technological backbone for the Internet and e-commerce. As of 2005, data centers accounted for 2% of total U.S. energy consumption. Data center managers cite power consumption as their largest concern today since: 1) energy costs to run servers are now typically greater than acquisition costs; and 2) excessive energy use produces heat that reduces system reliability. If successfully deployed, the proposed approach has the potential to address an emerging market pain point and to make a significant positive economic impact.
