  • WORK SMART Power Usage Effectiveness – PUE Reducing energy costs in your data centre Oct 201124/10/2011 Copyright 2011, All rights reserved 1
  • The need to measure Data Centre power The energy bill is the largest single item in the “total cost of ownership” of a Data Centre. Data Centres can use as much as 40% of the total energy costs in a business (source: a London bank) Copyright 2011, All rights reserved 224/10/2011
  • What is PUE? PUE = Power Usage Effectiveness PUE provides an industry standard ratio to measure the efficiency of the power used in a Data Centre PUE = Total Facility Power IT Equipment Power Copyright 2011, All rights reserved 324/10/2011
  • Making sense of PUE A PUE of 2 means that the Data Centre uses twice the power needed to run its IT equipment Example PUE = 2 – for every 1kW supplied, 500W is used by the IT equipment The most efficient Data Centres now have a PUE of 1.2, though the industry average is around 2.

  • Where is power used? Total Facility Power Electrical Auxilliary IT UPS Infrastructure Cooling External CRAC’s Chillers IT Servers IT Equipment By careful design, planning and operational practise data centre teams can make energy savings, reduce PUE to a minimum and maximize efficiency Copyright 2011, All rights reserved 524/10/2011
  • Reducing PUE Measure – AIT’s Data Centre Audit enables you to understand power usage and provides recommendations Optimise – AIT helps you optimise power, cooling and server efficiency, enabling you to make instant savings – Typical efficiencies: modern UPS, hot aisle separation system, electrical loading, temperature optimisation etc etc Monitor – AIT can installs and support Data Centre Infrastructure Efficiency (DCIM) tools to enable to monitor and further trim costs Copyright 2011, All rights reserved 624/10/2011
  • Effect of reducing PUE PUE = 2 PUE = 1.2 Industry average Best in class 10% 1% 1% 6% 1% 3% 9% IT Cooling 50% 36% Lighting 83% Aux UPS Reducing PUE dramatically improves IT efficiency Copyright 2011, All rights reserved 724/10/2011
