1 Data centres in 2009 What is happening to facilities? November 2009

2 Data centres in 2009 Should I teleconference or fly to California? Easy Should I teleconference or get the train to Luton? Harder

3 Data centres in 2009 Should I teleconference or fly to California? Easy Should I teleconference or get the train to Luton? Harder What is the cost of the activity without ICT? What is the cost of the activity with ICT? What is the cost of the ICT?

4 Data centres in 2009 Will green reduce ICT energy use? What about the Carbon Reduction Commitment? Metrics and labels? Per service accounting

5 Will green reduce ICT energy use? Data centres are not light bulbs We replace a 100W conventional bulb

6 Will green reduce ICT energy use? With a 20W high efficiency bulb To get the same amount of light for lower cost.

7 Will green reduce ICT energy use? Not in a Data Centre. Demand for ICT services is elastic If we make them cheaper, more will be consumed This may mean more energy if the elasticity is large Can t claim green based on reduced energy consumption

8 Some context for ICT energy What about the Carbon Reduction Commitment?

9 The Carbon Reduction Commitment You qualify if you consume over 600kW on half hourly meters Measured against your baseline year Hope your baseline year was a big one Rewarding those who were inefficient in the baseline year at the expense of those who had already improved

10 The Carbon Reduction Commitment What is the stick? You pay for carbon allowances (like ETS) You are put in a League Table (name and shame)

11 The Carbon Reduction Commitment Not that simple You pay for allowances, The revenue is then recycled back to you Based on what you paid? No, based on your baseline year Weighted on your position in the league table

12 The Carbon Reduction Commitment So how does the League Table work? You are scored on; Your net reduction in carbon from previous years Weighted by a revenue growth metric Your score is then; Ranked against every other organisation s score Summing up your League Table position is; Your relative performance against your baseline year, with a relative weighting for growth, measured relative to the relative performance of everyone else, with a relative weighting for their individual growth.

13 The Carbon Reduction Commitment What can t you do with CRC? Predict where you will come in the league table Predict what CRC will cost you Tell how green a company is by the league table position Tell how green a service or product is from the vendor s league table position, {construction equipment, data centres, laptops}?

14 The Carbon Reduction Commitment The CRC is structurally flawed The CRC drives the wrong behaviours The CRC is a complex accounting game You will probably get corporate & departmental targets for CRC So, how do you play the CRC game? CRC claims to be Inclusive But, CRC does not include your contract carbon

15 The Carbon Reduction Commitment Let s look at an organisation A number of activities Each activity uses resources Each resource costs carbon The Landlord Tenant structure applies the carbon to the meter holder, not the Consumer of the energy

16 The Carbon Reduction Commitment Use a Regus office and the carbon is their problem Use a Supplier data centre and the carbon is theirs Use thin clients and even your desktop carbon is laundered

17 Some context for ICT energy Metrics and labels?

18 Metrics and Labels Can we use metrics and labels to justify our energy consumption or demonstrate our green activity? Problems; Verifiability of claims Limited context for labels and metrics Most claims are perceived as just green paint

19 Metrics and Labels Green labels and claims LEED Platinum - Irrelevant to the data centre BREEAM - Irrelevant to the data centre Design PUE=X.X - Meaningless Green Tariff - No additionality, you just made the grid dirtier for everyone else

20 Metrics and Labels Data centre metrics The only metric that you can measure is PUE / DCIE - This is only a small part of the data centre efficiency - You cannot compare or target on DCIE Chained value metrics are conceptually flawed DCEP is not ready yet

21 Metrics and Labels EU Code of Conduct on Data Centres Independent Specific to the data centre Verifiable claim Use internally Use as a procurement tool

22 Metrics and Labels EU Code of Conduct on Data Centres First year update complete Logo being developed Changes to environmental specifications Air flow and network equipment

23 Some context for ICT energy Per service accounting

24 Per service accounting IT Value to the business Is not measured as Useful work Is a function of the business process the ICT service helps deliver IT Efficiency does not matter to the business Even if we could measure Useful work or Data Centre Efficiency IT cost matters

25 Per service accounting Cost black holes Shared infrastructure Virtualised servers and storage Applications moving from the desktop to the data centre Desktops moving to the data centre Lack of cost transparency The data centre is a larger part of the overall capex and opex of the company We can no longer account for which part of the cost delivered which value to the business

26 Server power at Utility (Watts) Per service accounting Metering fails Multiplying device power by PUE is not a useful proxy for cost or energy and cannot be used for chargeback How do you install a power meter on a virtual machine? Overall Server Power Fixed Overhead Variable Overhead Server Power Server metered power (Watts) Server Power * PUE

27 Per service accounting Model and understand the whole system We can use our understanding of how data centres work to put analytic capability into reporting DCiE by IT Electrical Load and External Temperature for Free Cooling DCiE % 75% IT Electrical Load 50% 25% 0% Temp

28 Per service accounting Re-connect with the business Cut through the layers and identify; - Marginal - Capital - Operational Cost of each service delivered to the business

29 Per service accounting Environmental Per service environmental costs allow us to; - Properly assess the ICT impact - Properly assess the net impact in the context of the physical processes reduced by the ICT service
