Green Computing?
Wikipedia
• The study and practice of using computing
resources efficiently.
• primary objective is to account for the triple
bottom line
– People, planet, profit
• The goals are to
– reduce the use of hazardous materials
– maximize energy efficiency during a product's lifetime
– promote recyclability of defunct products and waste.

3. The Government
• Cares what its customers say ...
– Climate Change Act
– Carbon Reduction Commitment
– EU Code of Conduct for DCs
The Climate Change Act 2008
• Introduced 11/07 & law 28/11/08
• First country to put emission targets into law
– 26% reduction by 2020
– 80% reduction by 2050
– Legally-binding 5-year budgets for greenhouse gas
reduction
• All primary greenhouse gases are included
• Carbon Reduction Commitment
http://www.defra.gov.uk/environment/climatechange/uk/legislation
The Carbon Reduction Commitment
• Mandatory cap and trade scheme for 04/10
– Affect approx 5K organisations with
Energy consumption of over 6,000MWh.
– Monitor and report their energy usage.
– Appear on a published league table
– Carbon Allowances around £12/tCO2e.
• An organisation consuming around 8,000MWh
could pay as much as £100,000 per year.

EU Code of Conduct for Data centres
• CoC is a voluntary initiative
– Based on US EnergyStar Data Center
Infrastructure Ratings.
– Develop and promote best practice for DCs
– monthly monitoring of energy usage
• Widely seen as “regulation through the back
door”
– “I view this [CoC] as a wider move towards mandatory
energy reporting for data centre owners and
providers.” - Alec Selvon-Bruce of Hitachi
http://re.jrc.ec.europa.eu/energyefficiency/html/standby_initiative_data centers.htm
“Western European electricity consumption [in DCs] for
2007 can be estimated at 56 TWh per year and is
projected to increase to 104 TWh per year by 2020.”
• Is “energy” a purchase criteria for your IT?
• It might be for your car… but IT?

the comfort of the
operators or hotspots
• In favourable climates
outside air can
work well
too.*

Virtualisation
Virtualisation pitfalls
• VM Sprawl
– Management of VMs is key
• Storage
– VMs are only part of the solution, don’t forget
storage virtualisation too
• IO bottleneck
– Understand IO requirements of VM candidates
– It won’t be the # VMs but amount of IO that
throttles the server
