Low Carbon Data Centres without compromise

Transcription

1 Low Carbon Data Centres without compromise Thursday 16 th September 2010 Pip Squire, Engineering & Project Director delivered by: Ark Continuity - Continuously Delivering high integrity data centres

2 Introduction Since this conference last year we: have completed SQ17 Module 1 have demonstrated a PUE of 1.4 during IST testing* are now operational with a capacity of: 800 kw of IT Load 600m 2 of supported Data Suite space Tier III Security to IL4 This presentation will look at: Whole Life Cycle Data Centre Costs Our focus on reducing carbon through efficient operation by sustainable design The benefits arising from this approach

3 Definitions Data Centre A Facility that is dedicated to Data Centre operations Whole Life 26 years from start of design to decommissioning and disposal Whole Life Costing... the systematic consideration of all relevant costs associated with the development and ownership of an asset Whole Life Stages Design, Build, Operate, Refresh, Decommission.

4 Definitions Power Usage Effectiveness (PUE) This is a metric for characterising and reporting overall data centre infrastructure efficiency based on annual energy consumption data as follows: PUE = Total Data Centre energy consumption/it energy consumption. Total Data Centre Energy Consumption is measured in kwh and is the sum of the kwh recorded on the utility company bills IT Energy Consumption is measured in kwh. It is the sum of the kwh recorded at the PDUs supplying the IT load. PDU Power Distribution Unit UPS Uninterruptible Power Supply Autonomy Time the UPS can supply the technical load without an incoming supply.

5 Whole Life Cycle Data Centre Costs Only 44% of IT Managers see their Data Centre Energy Bills (Institute of Engineering and Technology, November 2009)

6 Whole Life Cycle Data Centre Costs

7 Implementation and Impact on Whole Life Cycle Data Centre Costs Focus on continuous improvement in terms of: - Design with sustainability at its core - Operations

8 The Cycle of Continuous Improvement The Virtual Circle Driven by our systems that are accredited to: - BS :2007, Business Continuity Management - ISO/IEC 27001:2005, Information Security Management - ISO 14001:2004, Environmental Management

9 Linking Carbon Impacts with Whole Life Cycle Costs In our SQ17 Facility we have: 1. Measured our Construction Carbon Footprint, where we can: Our M&E Suppliers are still working on their embedded carbon calculations Shell & Core has 1,111 tonnes of CO 2 equivalent Anticipate a total of 3,000 tonnes of CO 2 equivalent including the M&E data Embedded CO 2 is 3,000 t per MW of IT Load

10 Linking Carbon Impacts with Whole Life Cycle Costs In our SQ17 Facility we have: 2. Calculated our Operating Carbon Footprint: At full load With an annual operating PUE of between 1.4 and 1.5 Based on the total UK electricity mix of coal, nuclear, oil, gas and renewable generation mix and the 5 year rolling grid average of 0.54 t CO 2 equivalent per kwh. As 6,600 to 7,000 tonnes CO 2 equivalent per year This provides: a) A saving of 3,500 to 4,000 t CO 2 equivalent a year over a data centre with a PUE of 2.5 b) The basis on which to build a carbon accounting tool for compliance with: - the CRC Energy Efficiency Scheme - the EU Code of Conduct on Data Centres

11 Sustainable Design - local renewable energy and water conservation Sustainable Design - local renewable energy and water conservation

12 Sustainable Design - local renewable energy and water conservation We anticipate that this will enable the site to achieve a PUE of around 1.2 and provide an annual saving of around 6,000 t of CO 2 per MW per year over an equivalent data centre with a PUE of 2.5

13 Sustainable Design - Power Usage Efficiency (PUE) PUE presented so far has been to 1 decimal place because: It varies with IT load, time of day and time of year. PUEs quoted have been unqualified in terms of support systems. At low PUEs the UPS efficiency and ancillary loads have a significant impact:

14 Benefits of Efficient Operation by Sustainable Design Operations, Design, Implementation and Research are all linked in a virtual circle. Development effort is focussed at the appropriate stages in the project life cycle to obtain maximum benefit for cost incurred Sustainable design means we are focussed on minimising our impact on the planet Risk management and the use of incentivised contracts mean we deliver to cost and programme

15 Benefits to Government ICT Sustainable Operations on the Government Estate (SOGE), have the following targets: Reduce Carbon Emissions on 1999/2000 levels by 12.5% in 2010 and 30% in 2020 Increase energy efficiency per m 2 on 1999/2000 levels by 15% in 2010 and 30% in 2020 Reduce water consumption on 2004/5 levels by 25% in 2020 Reduce waste arisings on 2004/5 levels by 5% in 2010 and 25% in 2020 Increase recycling to 40% in 2010 and 75% in 2020 The Ark SQ17 Facility: With a PUE of reduces data centre carbon emissions, over a 1999/2000 facility by more than 30%, i.e target delivered in Sustainable design and operating practices mean that we are already delivering the water consumption and waste reduction targets identified above

16 Our mission is to continuously deliver scalable and predictable mission critical infrastructure that is the most secure, resilient & sustainable in Europe. Thank you
