• In November, Dell announced that its<br />
corporate headquarters campus with<br />
17,000 employees is powered with 100<br />
percent ‘green’ energy, in fact its methane<br />
from a waste dump<br />
• We also achieved the target of being<br />
entirely carbon neutral across the globe 5<br />
months early in August 2008<br />

COSTS<br />
•Cost of running the Data Centre<br />
•An average build PE1950 1U Dual Core server<br />
in a large server farm costs €347 per annum,<br />
just to run the server!<br />
•This equates to 1525kG CO2 Per annum.<br />
Based on 0.527kG CO2 per KWH (UK Gov Figures)<br />
•The Energy Smart PE1950 saves between 12-<br />
16% of this cost. Or around €48 Per annum<br />

“MIXED” <strong>DATA</strong> <strong>CENTRES</strong><br />
<strong>HPC</strong><br />
MIXED DC<br />
•Higher power density, circa 10-25kW<br />
per rack<br />
•Mainly High density racks in the DC,<br />
few less than 7-8kW<br />
•Much higher utilisation rates 80-100%<br />
•Higher rack fill level 80-100%<br />
•Not usually possible to virtualise<br />
•Jobs typically run for many hours,<br />
possibly days.<br />
•Low power density, typically 3-7kW per<br />
rack<br />
•Mix of rack density, some running at 1-<br />
2kW<br />
•Typical utilisation rates of 1-20%<br />
•Rack fill levels typically 40-65%<br />
•Most corporates have embraced<br />
virtualisation to some extent<br />
•Overnight utilisation is rare.<br />

• <strong>IT</strong> Productivity…<br />
– Increases with each generation<br />
– Increases with better utilization<br />
– Grows exponentially as long<br />
as Moore’s law holds<br />
• Best case for Infrastructure Efficiency…<br />
– No power required for cooling<br />
– No losses in power distribution<br />
– Industry will succeed in reaching point<br />
of diminishing returns quickly<br />

•Chilled water is approx. 15% more efficient than DX (Gas)<br />
•Closed Cooling (Cooling rack & contents) is 30% more<br />
efficient than Open Cooling (Room Cooling) (ASHRAE)<br />
•Free Air Cooling can save up to 40% of the overall cooling<br />
costs or 10-12% of the overall DC power draw.<br />
•Gartner estimate that if power prices continue to rise then<br />
by 2010 the cost of the power for the DC will EXCEED<br />
the cost of the hardware<br />

WHAT IS<br />
FREE AIR COOLING?
<strong>DATA</strong> <strong>CENTRES</strong>; BETTER<br />
SOLUTI<strong>ON</strong>S<br />
• In Northern Europe for a greater part of the year<br />
the outside air temp is lower than the temp.<br />
required for the Data Centre<br />
• Free Air cooling utilises this lower outside air<br />
Temperature rather than running Chiller plant
<strong>DATA</strong> <strong>CENTRES</strong>; BETTER<br />
SOLUTI<strong>ON</strong>S<br />
• Typically you require a Delta of 7 o C between the<br />
outside temp & the Data Centre Temp.<br />
• Therefore to achieve 25 o C at the racks requires an<br />
outside Temp of

<strong>DATA</strong> <strong>CENTRES</strong>; BETTER<br />
SOLUTI<strong>ON</strong>S<br />
• Most manufacturers of closed coupled cooling<br />
state that they achieve a typical +/-1 o C Temp.<br />
Control across the full height of the Rack.<br />
• Therefore being able to run closer to the 25 o C<br />
intake target & guaranteeing no hot spots means<br />
utilising more free air cooling.
