1. Data Centre Environment

Why focus on Data Centres?

• Why are Data Centres at the forefront of environmental conversations?

– In 2005, 1% of the entire world’s electricity consumption was attributed to data centres alone. - EcoWorldly

– By 2020 the carbon footprint of the computers that run the Internet would be larger than that of air travel. - McKinsey study

– Data centres account for almost a quarter (23 per cent) of the 580 million tonnes of CO2 released annually by the production and use of computer systems, according to the latest research from analyst Gartner.

– Gartner study warns of a 1600% increase in data centre energy costs between 2005 and 2025.

– The world’s data centres are responsible for the same volume of carbon emissions as the average European country, and more than double those of Finland and Portugal.

• Why do data centres consume so much power?

– Organisations are growing their infrastructure exponentially and emissions from data centres are expected to double by 2012 – Power-hungry hardware and lack of floor space -which increases

Current efficiency initiatives

What is being done to improve ICT’s carbon footprint?

• As a result of current and planned power consumptions the ICT and supporting industries are employing new products, technologies and methodologies to address growing concerns. Examples include, but are not limited to the following:

– Products

• Efficient Chillers, Room Oriented, Rack Type, and Door Mounted cooling systems

• Best in breed Transformers – e.g. Amorphous Transformer • Diesel Rotary Uninterruptable Power Supplies (DRUPS) – Technologies

• Virtualisation aimed at improving server capacity management – Methodologies

• Use of free cooling in cooler climates can reduce and almost eliminate the need for legacy cooling equipment

• The use of wind farms are being considered

• Different technology companies have been in news for their varied attempts to use nature’s bounties to their benefit.

– Google’s “sea-faring solution”

– Fujitsu’s hybrid cooling approach in Sydney. – Hewlett-Packard’s Dynamic Smart Cooling initiative.

– Many others have sought cooler climates to render cooling-costs zero

• Although US vendors are developing similar systems, European market is still yet to come • More environment friendly and improvement in

TCO by adding free cooling function

• PAC for newly developed DC • Inverter control realizes less TCO

compared to chillers and free cooling which are major in Europe • More value added by IT/air-con

linkage control option
