3 THE DATACENTRE OF THE FUTURE A DATACENTRE IS NOT ABOUT ICT, POWER, COOLING OR SECURITY. IT IS NOT EVEN ABOUT SCALE OR AVAILABILITY OF THESE SYSTEMS. IT IS ABOUT THE AVAILABILITY OF INFORMATION

4 THE CHALLENGES INCREASE IN INFORMATION FOOTPRINT DEMAND FOR HIGH DENSITY CLOUD CONSOLIDATION OF POWER DEMAND OVERLOADING OF OUTDATED POWER GRID GLOBAL NETWORK LOAD CREATING EXERGY

5 ENERGY FOOTPRINT OF INFORMATION FACILITIES Datacentres, Server rooms, Network hubs etc. Estimated 4% Global Electricity Production (25 PWh) 4% = 1 PWh Wh (10 15 )

6 EXPLANATION PREVIOUS SLIDE (ENERGY FOOTPRINT) There is no real data available which can substantiate any sort of claim to the percentage mentioned. It is a very rough estimate for a global scale. The fact that the information is unavailable, is part of the problem. You cannot solve the problem which cannot be identified. The only available source for a global figure is the European Commission where Neelie Kroes mentioned datacentres being responsible for 2% of the global electrical energy production and ICT in general being responsible for 8-10%. (2012)

7 GLOBAL PUE: APPROX. 1.7 UPS/Nobreak 2% Other 2% Global estimated PUE breakdown Cooling 37% ICT 59% Fans (20%) 10% Information (65%) 40% Power supply (15%) 9%

8 EXPLANATION PREVIOUS SLIDE (GLOBAL PUE ESTIMATE) There is no real data available which can substantiate any sort of claim to the percentages mentioned. Everything is a very rough estimate for a global scale. For both the Power supply and Fans percentages, the estimates are based on the following factors: Most datacentres (colo) have no control over the internal temperature management of the IT. Environmental temperatures in datacentres are usually too high for optimal power efficiency of IT. IT is in general greatly under-utilised (30% is already high in many cloud environments, corporate IT in colo is often worse) which creates a very high overhead for both the PSU and fans. Most cloud and corporate backoffice platforms are running on inefficient, cheap IT hardware which is driven by CAPEX as opposed to OPEX. Reason for this is that power consumption is not part of the IT budget. Virtually all high density cloud environments (5-10 kw/rack) are based on 1U servers. These are the least efficient when it comes to fan overhead.

9 ACTUAL INFORMATION EFFICIENCY Actual efficiency 1000 TWh total energy Actual cooling: 471 TWh Actual power loss: 112 TWh 112 TJ/s Other overhead: 17 TWh 17 TJ/s Energy for information: 400 TWh 400TJ/s Information 40% Cooling + IT fans 47% 1000 TWh/400TWh PUE equivalent: 2.5 Other 2% UPS+IT Power supply 11%

10 ENERGY TRANSFORMATION Global thermal energy production by Information J or 1.9 EJ (10 18 ) (529 TJ/s*3600): Energy for heat rejection EXERGY DESTRUCTION: Wh

11 WHAT IF INFORMATION FACILITIES COULD... EXCLUDE COOLING INSTALLATIONS REDUCE IT OVERHEAD BALANCE THE POWER GRID REDUCE THE DATA NETWORK LOAD BECOME ENERGY PRODUCERS

12 COOLING THE CLOUD 1 MW critical load, ΔT of 10 C Thermal production: 1MJ/s 1 C rise with air: 1005 J/kg C * kg/l = J/L/s 1MJ/s requires: J/(10 C *1.2 J) 83333L/s AIR

13 83333 L/s AIR VS WATER 1 MJ/s Water required for ΔT of 10 C 4187 J/kg C * 1 kg/l = 4187 J/L/s per 1 C 10 C with 1 MJ/s: 24 L/s Liquid can travel 200 TIMES THE DISTANCE with same thermal losses THE DATACENTER OF THE FUTURE: 6 L/s AND IS AN ENERGY PRODUCER...

14 EXPLANATION PREVIOUS SLIDES (WATER VS AIR) For simplicity, the identical ΔT is maintained for both approaches. After feedback from reviewers and the audience of Datacentre Transformation Manchester, the comparison was raised to 10 C Air will usually allow the ΔT to become higher than 10 C, although due to poor utilization, this is not always achieved. In CRAC water circuits, the ΔT is usually below 10 C.

15 THE WRONG QUESTION DON T ASK WHICH TECHNOLOGY TO USE CHOOSE BETWEEN AIR OR LIQUID THEN COMBINE LIQUID TECHNOLOGIES

16 TLC - IMMERSED COMPUTING 100% Removal of heat from the IT Highest IT efficiency by eliminated fans No air required Level of intelligence Management control and insight Automatic optimisation of the water circuit Optimised for high density cloud/hpc nodes Varying servers Flexible IT hardware Feed: C / 55 C Extreme / max ΔT 10 C

17 DLC - DIRECT-TO-CHIP LIQUID COOLING Removes heat from hottest parts of the IT Increased IT efficiency by reduced fan power Requires additional cooling (ILC) Level of intelligence Management control and insight Automatic optimisation of the water circuit Optimised for HPC racks with identical nodes Very high temperature chips High density computing Feed: C / max ΔT 15 C

18 ILC - (ACTIVE) REAR DOOR COOLING 100% Removal of heat from the IT Small IT efficiency by assisted circulation Acts as air handler in the room Level of intelligence Management control and insight Automatic optimisation of the water circuit Optimised for IT with limited liquid compatibility Storage Network Legacy systems and high maintenance servers Feed: C / 28 C Extreme / max ΔT 12 C

19 OPTIMISING LIQUID INFRASTRUCTURES TECHNOLOGY NORMAL INLET OUTLET CRAC (generic) 6-18 C C ILC (U-Systems) C C DLC (Asetek) C C TLC (Asperitas) C C TECHNOLOGY EXTREME INLET OUTLET CRAC (generic) 21 C 30 C ILC (U-Systems) 28 C 32 C DLC (Asetek) 45 C 65 C TLC (Asperitas) 55 C 65 C
