Overview

• Big Picture– Why Measure– What to Measure– How To Measure

• Visualization Primer• Case Study• Summary• Q&A


Why Measure

• Service Level Agreement (SLA)• Information Technology

Infrastructure Library (ITIL)• Total Cost of Ownership (TCO)• Actual Versus Designed• Stranded Capacity• “Can’t Manage What You Can’t

Measure”


Energy Cost Projection

Energy Benchmark

• Established Benchmark

• Enables Comparison


Source: The Green Grid

Energy Consumers

• 70% of Power Consumption Goes to the Infrastructure

• Over Twice that of the IT Equipment

What To Measure

• Power

• Temperature

• Air Pressure

• Humidity

• Water Flow & Temperature


Best Practice Opportunities

• Chilled Water

• Fans

How To Measure

• Level of Precision

• Alternatives– Point In Time– Ongoing– Real-Time

• Modeling Tool Requirements


Visualization Tools

• System Admins

• Network Admins

• Data Center Managers


Real-Time Imaging


CFD Visualization

Computational Fluid Dynamics (CFD)


Case Study

• Lawrence Berkeley National Lab– Continued Increase in Demand– Data Center Capacity ~2011– Strategic Imperative on Efficiency

• Study Results– Improve Airflow– Virtualization– Water Cooling
