Growth Projections what are the experts saying?

2008, 50% of today’s data centers will have insufficient power and cooling capacity to meet the demands of high-density equipment

Through 2009, energy costs will emerge as the second-highest operating cost (behind labor) in 70% of DC facilities WW

2011, power demand for high-density equipment will level off or decline

2011, in-rack and in-row cooling will be the predominant cooling strategy for high-density equipment

2011, in chasis cooling technologies will be adopted in 15% the servers

405.5B KWh

Generation and Consumption “Coal Fired Packets”

Our Impact as DC Professionals

It Requires 838 lb’s of coal to power one PC for

one Year!

Power Supplied in the DC CRAC 50%

Server/Storage 26%

Conversion 11%

Network 10%

Lighting 3%

Each watt consumed by IT infrastructure carries a “burden factor” of 1.8 to 2.5 for power consumption associated with cooling, conversion/distribution and lighting* Source: APC

Where does the Power Go? Losses in power generate heat


Cooling – Supply or Distribution? Current designs being specified to cool up to 30kW per rack

• Cisco Partner tested at 30KW and were able to cool in a normal server rack • Tested different configurations and had very different cooling airflow results • Targeted cooling utilizing modular hot/cold segregation essential to “future-proof” designs

Supply? Distribution?

Data Center Evolution

Consolidation • Reduce Operating Expense

• Can Strain Power Grids, HVAC Systems, and Control Planes

• Also an Opportunity to “Audit” Power and Cooling Design

Power & Cooling • Reduce Component Count

• Increases Density

• Assessment Needed to Determine OPEX for site

• Assessment may be Needed to Audit Existing CPI

Best Practices • Choose Efficient

Components (Systems)

• Balance Density/Space

• Assess new Technology

• Targeted, Incremental Changes for Efficiency

• Virtualize to Increase Utilization

• Share Practices
