June 21 - 25, 2008

The following will be presented at the Ashrae Annual Meeting Salt Lake City, UT:

Transactions Session 7 (Intermediate)
Monday 6/23 9:45 AM – 10:45 AM
Room: I

Modeling Data Center Airflow and Cooling Performance
Track: Applications
Room: I
Sponsor: 4.10 Indoor Environmental Modeling; 9.9 Mission Critical Facilities, Technology Spaces and Electronic Equipment Chair: H. Ezzat Khalifa, Member, Syracuse University, Syracuse, NY

Sensitive electronics equipment housed in datacenters must receive sufficiently cool air to operate reliably. As datacenters are huge consumers of energy, there is great incentive to provide the required cooling as efficiently as possible despite unique facility and cooling architectures, continued rise of equipment power dissipation, large variations in power and airflow requirements among neighboring equipment, and the transient nature of computer workload. Predictions of datacenter airflow and cooling performance are needed to optimize datacenter architecture before initial build-out or equipment changes. This session addresses CFD and other novel computational techniques for modeling datacenters airflow and cooling.

1. Coarse-Grid CFD: The Effect of Grid Size on Data Center Modeling (SL-08-017)
James VanGilder, Member, Xuanhang Zhang, American Power Conversion, North Billerica, MA

2. Airflow and Cooling Performance of Data Centers: Two Performance Metrics (SL-08-018)
Magnus K. Herrlin, Ph.D., Member, ANCIS, San Francisco, CA

Seminar 46 (Basic)
Tuesday 6/24 9:45 AM – 10:45 AM
Room: F

Panel of Existing Benchmarking and Metrics Affecting the Data Center
Track: Benchmarking
Room: F
Sponsor: 9.9 Mission Critical Facilities, Technology Spaces and Electronic Equipment
Chair: Christian Belady, P.E., Associate Member, Microsoft, Redmond, WA 

This panel of speakers provides an overview of various metrics that have emerged and will be deployed in data centers in the coming years. Metrics for data center efficiency and server efficiency are highlighted by the following organizations: SPEC, EPA/DOE, The Green Grid and Climate Savers. The attendees should get a good overview of metrics and benchmarks they should be considering. 

1. Michael Patterson, Ph.D., P.E., Member, Intel, Hillsboro, OR
 – representing Climate Savers Computing Initiative

2. Tahir Cader, Ph.D., Spraycool, Liberty Lake, WA
 – representing The Green Grid

3. Kushagra Vaid, Microsoft, Redmond WA
 – representing SPEC

4. William Tschudi, P.E., Member, Lawrence Berkeley Laboratory, Berkeley, CA
 – representing the DOE
