Business IT energy efficiency is an approach for improving the energy efficiency associated with IT equipment. The basic methodology is to

  1. Measure the current situation to establish a baseline
  2. Identify opportunities for efficiency improvements
  3. Establish targets and policy
  4. Develop roadmaps, obtain budget and establish projects and governance to achieve outcomes

[edit] 1. Establish baseline power usage of IT equipment (and premises)

This should include:

  • Total power consumption for data centres (may require some data consolidation &/or data warehouse work)
  • Power consumption of "equipment types", e.g.
  • Server type 1 (entry)
  • Server type 2 (mid, dual processor)
  • Server type 3 (mid, 4-8 multi processor)
  • Mainframes
  • Desktops

Include audits of total numbers of various hardware types, and link power consumption to greenhouse emissions.

[edit] 2. Research characteristics of modern processors

(e.g. multi core, 60nm, low power etc)

  • Identify candidates for new models to replace existing units
  • This could include consolidation of numerous "horizontally scaled" individual servers onto bigger multicore and multiprocessor servers (may also require server virtualisation)
3. Put in place targets and a roadmap

  • Establish achievable emission reduction targets (e.g. reduce CO2 emissions by 15% in 2007/2008).
  • Establish a roadmap for achieving the targets (e.g. server refresh and/or consolidation, desktop refresh etc)
  • Establish cascading accountabilities for delivery
  • Establish a governing body of key management stakeholders to monitor progress
  • Measure progress regularly (at least monthly)
