Hitachi Eco-Friendly Data Centre Solutions Why are efficient data centres a necessity and how can they be delivered 24 th September 2009 1 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 cooling requirements -are key factors in spiralling energy consumption. 2
1. Data Centre Environment 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 3 2. Current Green IT Challenges New DC Power Efficiency Benchmarks INDUSTRY EXAMPLE DATA CENTRE POWER USAGE EFFICIENCY (PUE) METRICS Source: Metrrics to Characterize Data centre & IT Equipment Energy Use (C Malanoe and C Belady) Power Usage Effectiveness (PUE) is a standard developed by The Green Grid consortium to provide a clear answer to the primary issue surrounding energy efficiency within the data centre which is how much power is devoted to driving the actual computing/it components (servers, for example) versus the ancillary support elements such as cooling and lighting. 4
