Founder & CVO Peter Hopton shares his thoughts on liquid cooling for the data centre at Machine Evaluation Workshop.

1. It’s Getting Hot In Here
New solutions for data center cooling
November 2014

2. The Advancing Trend
Moving From Air to Liquid
• Many industry experts and vendors recognise liquid cooling is the future for data centres
• Liquids Carry 1000’s of times more heat per volume
• At ISC this year, 21 different liquid cooling solutions were exhibited
• This presentation highlights the trend and offers Iceotope’s perspective, as well as giving an
insight into Iceotope’s patented technology.
• Liquid cooling is being adopted for a variety of reasons:
• Efficiency
• Density
• Total Cost
• Hostile or Complex Environments

3. From Air To Liquid
Cooling
Liquid Cooling
Direct Liquid Cooling
Total Liquid Cooling
• Air is passed through servers and then through a
rear door or in row air-water heat exchanger.
• Liquid is taken direct to some components
• Fans are still needed.
• All components are cooled directly by liquid. Air
side losses are minimised.
• Inside the DC, the system has no fans and
breathes no air.

4. The Benefits of Advancing
Liquid Cooling Technolgies

Direct Liquid Cooling
Total Liquid Cooling
• Offers Better Density
• Offers Better Efficiency.
• Offers better Density
• Offers better Efficiency.
• Eliminates/Massively Reduces air based
infrastructure. (Fridge Argument)
• Offers better efficiency still.
• Density is high, especially overall.

8. The Cost Reduction Oasis

9. Who Are Iceotope?
• British Startup company based in Sheffield, UK
• Backed By:
• Schneider Electric
• Solvay Specialist Plastics
• Additional partnerships with:
• Intel
• 3M
• ASHRAE W4 & Total Liquid Cooling

10. Our Ethos:
The Elimination Of Waste
1. Waste infrastructure required to support servers
2. Waste power consumed in supporting the
electronics – and running the same electronics with
greater speed and efficiency
3. Waste product – producing a viable waste product
in the form of hot water

11. Air Conditioners
IT Cabinets
AKA “Racks”

Power Distribution
1. TLC needs no
A/C
3.TLC servers
have no fans –
use less power
2. No Airflow, no
raised floor
4. No A/C,

13. Cooler Servers Run Faster
& More Efficiently
• Cooler servers better leverage Turbo modes
• Dual E5 2699 v3 processors supported
• Up to 60kW (72 Blades per cabinet)
• Up to 14kW/sqm
• Up to 45C (113F) input coolant

14. Real World Results
• Cooling Overhead (internal): as low as 0.33%
• Cooling Overhead (external): 1.7% - 4% (pPUE 1.017-1.04 @30KW/cab)
• Poznan National Supercomputing Centre indicated 1.7% (2% overall) average
• Romonet indicated 4% cooling overhead in 2N model in Houston Texas
• IT Energy Reduction vs Fan Cooled: 8%
• Based on measurements at Leeds University (Chi et Al 2013)
• Overall performance per watt benefit vs equivalent servers in a high
density, close coupled cooling environment: 40.8%
• Based on studies at Leeds University (Chi et Al 2013)
