HP developing modular data center technologies

The U.S. Department of Energy (DOE) has awarded us a $7.4 million grant as part of the American Recovery and

Reinvestment Act of 2009. The HP Rack and Power Group and the Eaton Corporation will co-develop power and cooling

technologies for a fully enclosed IT rack system. Wide acceptance of these technologies can significantly increase energy

efficiency and reduce carbon dioxide emissions.

About the grant

The grant funds the research and development of a self-contained IT rack enclosure with chilled water and high-voltage AC

inputs. The enclosure must also accept power from renewable energy sources such as wind and solar. The grant covers 80%

of the anticipated project cost with HP and Eaton responsible for the remainder. We must complete the project within 2

years from the February 2010 award date and make public the technologies developed under the grant. The products that

result from these new technologies will create U.S. jobs, provide a more efficient means for the IT industry to use wind and

solar energy, and extend the life of data centers around the globe.

This is the first time that the DOE has awarded a grant to an HP product development team. A key reason is that we, and

Eaton, have previously investigated some of the required systems. This makes it possible to complete the project within the

two-year window.

The target markets Ken Baker, HP Data Center Infrastructure Technologist, says, ―Existing self-contained rack enclosures, including the HP Modular Cooling System, work well for high-density racks with heat loads above 10kW. But the majority of the market consists of small and medium data centers with partially full racks and heat loads ranging from 3kW to 7kW per rack.‖ These data centers typically have power and cooling constraints rather than space constraints.

Energy savings We believe the MDC will cut energy use by 38% for a 100kW IT load based on increased efficiency for cooling power conversion. This is equivalent to reducing carbon dioxide emissions by approximately 400 tons annually.

The iLO user interface System-specific Sensor Data Records (SDRs) determine which thermal sensors the iLO user interface (UI) displays. The Intelligent Platform Management Interface specification defines the Sensor Data Repository, which houses SDR’s. The system BIOS transfers the Sensor Data Repository to iLO during POST. iLO consolidates data from a group of similar sensors (DIMMs for example). In aggregate readings, SDRs send the temperature of the warmest component in a group to the iLO UI.

long as the server can deliver the next chunk of the video stream in the required window of time. However, if the latency exceeds 1000 milliseconds, you will probably see a glitch or a pause in an on-demand movie. Smart Array controller optimizations for VOD Smart Array engineers analyze VOD requirements and use this information to optimize the Smart Array controller using the Array Configuration Utility (ACU). Some configuration parameters require a Smart Array Advance Pack (SAAP) license to access.

Meet the Expert—Chris Wanner Chris Wanner is a Signal Integrity (SI) Program lead for the HP BladeSystem c-Class servers. Chris joined Compaq in June 1986 when it had less than 3,000 employees. His current responsibilities include HP BladeSystem architecture and Signal Integrity as well as CPU roadmap performance analysis. According to his manager, Gene Freeman, ―Chris has a broad understanding of the hardware architecture from sheet metal to processors to ASICs [Application-Specific Integrated Circuits].
