It’s Getting Hot In Here New solutions for data center cooling

November 2014

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

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.

The Benefits of Advancing Liquid Cooling Technolgies

Liquid Cooling

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.

The Cost Reduction Oasis

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

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

Air Conditioners

IT Cabinets AKA “Racks” Each contains 10-20 Servers

Raised Floor

Back Up Batteries AKA “UPS” Generators

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, average and peak power consumption reduced

The Iceotope Revolution

The Iceotope Blade, developed in partnership with Intel, is sealed electronics are immersed

Exotic Coolant

High Thermal Expansivity

Electrical Insulator

Certified non-flammable

Non Ozone depleting

Clean & Safe

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

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)
