Food for thought More than 40% of power going into a typical data center goes to the power and cooling systems NOT to the IT loads The typical 1MW (IT load) data center is continuously wasting about 400kW or 2,000 tons of coal per year due to poor design (DCiE = 50%, instead of bestpractice 70%) Every kw saved in a data center saves about $1,000 per year Every kw saved in a data center reduces carbon dioxide emissions by 5 tons per year Every kw saved in a data center has a carbon reduction equivalent to eliminating i about t1 car from the road A 1% improvement in data center infrastructure efficiency (DCiE) corresponds to approximately2% reduction in electrical bills

Power and cooling: The new #1 data center issue Rising densities have led to an increase in power and cooling issues 2008 IDC study
Challenges to COOLING Example: COOLING requirement for an 20 kw rack = 2,100 cfm per rack Floor tile 300 cfm Would require 7 vented floor tiles per rack (7x more than normally allocated) Floor tile 300 cfm Requires substantial increases in aisle width and spacing between racks Clogged raised floors compound the problem Floor tile 300 cfm Floor tile 300 cfm Floor tile 300 cfm Floor tile 300 cfm Floor tile 300 cfm White paper 46 Raised floor, perimeter-cooled data centers face practical limitation of approximately 5 kw (average) per rack
Challenges to POWER White papers Breaker chaos Insufficient breaker positions Cascading panels Mislabeled or unlabeled breakers Becomes worse withredundancy Adding new voltage levels & receptacle types to the rack Increases need for hot work Trend towards minimizing hot work Getting more power to the rack 28 29 Avoid tripping breakers COMPLEXITY increases likelihood of downtime
Challenges to SPACE and CABLING Floor loading of fully loaded high density rack Sub floor weight bearing limitations Supplemental raised floor pedestals may be required Airflow limitations of front and rear doors Cable chaos Risk of blocked airflow and human error from proliferation of cables in the rack Without effective high-density implementation, rack and cable challenges proliferate

Is there an efficiency vs density tradeoff? High density and high efficiency are related Manypeople think high density makesefficiency efficiency worse Only true when trying to push existing data centers to cool high density High density enables high efficiency in a properly designed new data center or a pod in an existing data center Shorter pipe lengths Less pump power Shorter air flow lengths Less air mixing Less fan power Higher return air temperatures Less humidification/dehumidification power and chiller power The highest efficiency data centers will be high-density h i data centers
