Energy efficiency emerging as a top Concern of data center managers What are your top facility / network concerns? Source: Data Center Users’ Group Surveys

What are your top facility / network concerns?

IT perspective on energy efficiency Top priority is delivering on service level agreements Performance - provide adequate compute capacity Reliability - redundancy at all steps Ability to support Security Does IT care about energy efficiency? Yes, but not if it impacts performance and reliability What if it frees up power and cooling capacity? Yes! If it does not impact performance and reliability

Top priority is delivering on service level agreements

Performance - provide adequate compute capacity

Reliability - redundancy at all steps

Ability to support

Security

Does IT care about energy efficiency?

Yes, but not if it impacts performance and reliability

What if it frees up power and cooling capacity?

Yes! If it does not impact performance and reliability

What data center managers are looking for Objective ‘vendor-neutral’ analysis Holistic view of the data center Quantification of savings from different strategies Prioritization of actions Actionable advice Tailored to different types of data centers 24x7 vs. 8x5; compute-intensive vs. transaction-intensive Payback/ROI analysis to help sell to management

Fact: No universal metric for data center output In the absence of this metric, discussing data center efficiency is not meaningful. We can only talk about reducing data center energy consumption.

Energy Logic: What is it? Emerson Network Power approach to reducing data center energy consumption Sequential roadmap that starts with IT equipment and moves through to support infrastructure Emphasis is on cascade of savings Based on research and modeling Provides quantified savings and an estimated ROI Frees up power, cooling and space capacity without compromising availability or flexibility

Emerson Network Power approach to reducing data center energy consumption

Sequential roadmap that starts with IT equipment and moves through to support infrastructure

Emphasis is on cascade of savings

Based on research and modeling

Provides quantified savings and an estimated ROI

Frees up power, cooling and space capacity without compromising availability or flexibility

Energy Logic: Three key messages 1. The most effective strategy to save energy: Start with reducing losses / consumption at the IT equipment level and work your way back through the supporting equipment Every watt saved at the equipment level has a cascading effect upstream 2. As you reduce energy consumption, make sure you do not compromise on availability and flexibility Efficiency Without Compromise TM 3. High-density architecture helps reduce energy consumption

1. The most effective strategy to save energy:

Start with reducing losses / consumption at the IT equipment level and work your way back through the supporting equipment

Every watt saved at the equipment level has a cascading effect upstream

2. As you reduce energy consumption, make sure you do not compromise on availability and flexibility

Efficiency Without Compromise TM

3. High-density architecture helps reduce energy consumption

Energy Logic: Model assumptions Model helps quantify impact of actions 5,000 sq. ft.
