4 Learn whether air containment is the right solution for you. See examples of realworld containment installations. Find out how to make the business case.

5 Containment Systems Efficient use of cool air Not just about aisle containment Scalable Flexible Affordable

7 Which cooling technologies are your colleagues using to improve PUE? Aisle Containment Increase inlet temperature Variable fan speed Air Economizer Water Economizer Evaporative Cooling Liquid Cooling

8 What is driving your interest in containment?

9 5 things you can expect from containment

10 1. Create additional capacity 20 % = 49 % Lower fan speed Less fan power used Reduced Power Consumption = Free Capacity

11 2. The ability to accommodate future equipment upgrades and grow your capacity 67% projected growth in heat loads by 2020

12 3. Elimination of hotspots and equipment shutdowns Open Chaos System Containment system

13 4. The ability to plan with a greater accuracy More uniform gradients and steadier flow

14 5. Cost Reduction Containment = Higher A/C Set Points = Lower Costs

29 Making the business case for containment

30 What is your current average PUE?

31 Making the business case: Cost comparisons to other options Scenario: 40 racks in the existing whitespace Chaos cooling approach using multiple A/C units Plenty of spare u-spaces to expand into, but the A/C is maxed out Goal: accommodate additional equipment without causing heat issues What are your options? Build a new facility Install another A/C unit Expand into a colocation facility Full-site containment

32 Making the business case: Cost comparisons to other options Options > 1. Build a new facility 2. Install another A/C unit 3. Expand into a colocation facility Investment: $ Millions $ 200, ,000 $ 0 5,000 OPEX increase: $ Tens of thousands $ Hundreds or thousands $ Thousands 4. Containment $16,000 20,000 ($ per rack) $ 0 (With likely savings on monthly cooling costs.) Timing: Months to years Months Weeks Days to weeks Outcome: Capacity problem X Heat in existing facility X Uncertain. Capacity problem X Heat issues in existing facility X Two facilities to manage Heat issues in existing facility Net new capacity May result in cooling redundancy

33 Making the business case: ROI Estimates Scenario: Full-site containment installation Total equipment power draw: 100kW Current PUE: 2 Total power used before containment: 200kW Expected reduction in PUE: 10% Expected Power usage saved: 20kW Yearly OPEX savings: $8, in power alone Total power saved each year: 20kW x 24h x 365 days = 175,200

34 Before you explore containment Are your racks properly sealed? Are you using proper cable management techniques? Have you removed all airflow obstructions underneath the raised floor? Have you sealed any gaps between the floor tiles? Do you have enough perforated floor tiles in place? Are the perforated tiles located in right places? Have you checked for cold-air bypass? Do you have spare capacity if one of the A/C units fails?
