5 'Shared services': Increased energy efficiency via consolidation in larger facilities? Dr Ian F Bitterlin PhD BSc(Hons) BA DipDesInn MCIBSE MIET MIEEE MBCS MBIFM Prism Power Ltd, UK

6 Three steps to Sustainability Reduce consumption – The social & economic value of the data processed? Improve efficiency – Not just PUE but also IT software & hardware Use energy from renewable sources – Building a legacy datacentre next to a hydro- electric scheme is NOT a sustainable design, it is a waste of valuable green energy on an inefficient data centre

7 Value of the traffic? Rise of the Hyper Giants: Five years ago, Internet traffic was proportionally distributed across tens of thousands of enterprise managed web sites and servers around the world. Today, most content has increasingly migrated to a small number of very large hosting, cloud and content providers. Out of the 40,000 routed end-sites in the Internet, 30 large companies – hyper giants like Limelight, Facebook, Google, Microsoft and YouTube – now generate and consume a disproportionate 30% of all Internet traffic.

8 Targets should be IT & Cooling?

9 IT hardware efficiency = 0%? Worldwide chip utilisation = ~5% IT power = chip, memory, drives, I/O, power conversion & fans At ~5% IT load the average server draws >60% power

10 Where the power goes … PUE=1.6 IT load Distribution & UPS losses Cooling fans, pumps & compressors Lighting & small power Security, BMS Ventilation – Fresh Air Communications 5 kW 15 kW 240 kW 500 kW 35 kW 3 kW 2 kW Total 800 kW 1MVA PUE = 800kW/500kW = 1.6

11 What is the PUE?

12 Key factors for high efficiency High efficiency servers & software Heavy Virtualisation – Multiple applications per server High load Vs capacity, M&E Free-cooling or Fresh-air cooling Relaxed set-points for temperature + humidity Strict air-flow management High efficiency UPS

13 Free-Cooling – not free, but cheap

14 Free Cooling Vs temperature

15 Electrical systems: Efficiency Vs Load

16 Easy to do on a large scale Leverage infrastructure, NOC etc Modularise Consolidate the load(s) Build rooms and you grow Manage the load Vs capacity Be clever with the redundancy strategy

17 Hard to do on a small scale? Predict the system capacity to get the end-game plan right – Room will generally end up too large running at too low a load with the future in mind Keep the UPS system load high without having too much modularity – Likely to be running at 30% load & 80% efficiency Introduce free-cooling – Most likely to be split air-con with CoP of 3-4 instead of 1.15-1.30

18 What could the impact be? 100 small data-rooms, 10 cabinets of 2kW each, 20kW IT load but designed for 50kW, each operating at PUE 3 of 2.5 – Total demand = 5MW One colo-facility of 200 cabinets of 6kW operating at PUE 3 of 1.3 – Total demand = 1.6MW – c70% reduction
