THE DARK FOOTPRINT OF THE KNOWLEDGE ECONOMY Heavy Burdens
PRODUCTION BURDENS A typical semiconductor facility: - 591 million gallons DI water - 5.2 million pounds of chemicals - 8.8 million kwh of electricity PC/LCD production - 1,000+ hazardous substances High energy materials - 2.5 tonnes of rock - for 1 gram of gold
THE DARK FOOTPRINT OF THE KNOWLEDGE ECONOMY Heavy Burdens and. Steam Computers
SUSTEIT HE FINDINGS Sheffield - 1 million + electricity bill - 47% desktop related HE sector wide - 760,000 PCs - 215,000 servers - 147,000 networked printers - 60 million + energy bill - 35/40% data centres/hpc
2010 AGENDAS Desktop energy efficiency - lower power - power management Data centre energy efficiency - air management - free/controlled/new cooling - power supply/conditioning Synergistic architectures - thin/thick/think client - virtualisation (& powerdown) Greening by ICT
GOVERNMENT CIO ADVICE - 1 Remove active screensavers Switch Monitor to Standby Shut down PCs OoH Active power management Re-use, re-cycle or green disposal Low power CPU & high efficiency PSU Thin client Timer switches for non networks devices Set default green print settings
GOVERNMENT CIO ADVICE -2 Optimise printer power saving Printer consolidation Device consolidation Server Optimisation Reduce data centre cooling Decommission redundant devices Ensure re-use of serviceable equipment Data Centre Audit
DATA CENTRE OPPORTUNITIES Power management Consolidation/Virtualisation More efficient device design More efficient storage Better air management Free/efficient cooling Innovative cooling Flexibility and control Power Conversion & Distribution Server Load/ Computing Operations Cooling Equipment Voltage optimisation Use of DC power Highly efficient UPS systems Efficient redundancy strategies Alternative Energy Supply On-site renewables Waste heat for cooling Fuel cells Thermal storage
DATA CENTRE PUE Power Usage Effectiveness - ratio of total energy (ie servers + support) to server energy 1990s centres 2.0 + University of Cardiff 1.3.1.4 University of St Andrews 1.2 Cap Gemini, Swindon 1.1??? CSC, Finland 1.06
(MORE) EFFICIENT STORAGE OPTIONS Manage - policies; deduplication Optimise - new configurations Replace - more for less efficient devices Extend - cloud, shared services
HILLINGDON 26,500 power savings pa from: Storage management - automated tiering - thin provisioning Storage energy efficiency - less fibre channel - more SATA Virtualisation - 94 production servers to 3
ICT BENEFITS SMART 2020 Benefits - 15% cut in CO 2 emissions by 2020 - $946 billion of cost savings - 5:1 CO 2 avoidance/creation ratio Means - smart grid - intelligent buildings - new ways of working
