The Challenge

It’s not easy being green

The power bill alone sometimes doesn’t tell the whole story…



Supply and Demand

Data continues to grow exponentially – 1998 Estimated size of Web - 320 million pages

– 2000 Estimated size of Web - one billion pages

– 2003 Google claims a searchable database of 3.6 billion web pages

– 2003 Estimated total corporate data worldwide – 5 Exabytes (5 billion GB)

– 2005 Google claims a searchable database of 8.2 billion web pages

– 2006 Estimated total corporate data worldwide – 161 Exabytes

– 2007 Estimated total corporate storage capacity worldwide – 246 Exabytes

– 2007 Projected total corporate data generated worldwide – 255 Exabytes

– 2010 Projected total corporate data worldwide – 988 Exabytes ~ 1 Zettabyte

– 2010 Estimated total corporate storage capacity worldwide – 600 Exabytes

Power to operate data centers will be more expensive

and scarce– Potentially half of the world’s data centers will have insufficient power by

2009 ** Gartner



The Industry Climate Today

� Government regulations, industry guidelines, and

international requirements are becoming stricter

� The amount of available energy is shrinking

� According to www.ReadWriteWeb.com, “Going Green”

was the second-largest data centre trend for 2008.



Going Green: Financially

Savings:� IT operating costs

� Capital investments

� Cooling and facility energy

Sustainability:

� Energy resources

� Protect availability

� Utilize infrastructure more efficiently

� Optimize available space

� Reduce environmental impact



Rightsizing the InfrastructureDelivering the correct capacity at the correct time

� Design focus is always around end capacity

� Lifecycle operations are often ignored

� Growth projections are becoming less reliable as new hardware is developed and deployed

� Energy consumption as measured against work performance is improving

� Battery infrastructure is often replaced before it is even needed



Key issues facing data center & network

managers today

Analyst Report on “Green” Data Centers

“… power efficiency is the starting point but not sufficient

on its own. ‘Green’ requires an end-to-end, integrated

view of the data centre, including the building, energy

efficiency, waste management, asset management,

capacity management, technology architecture, support

services, energy sources, and operations.”

Rakesh Kumar, VP at Gartner “Gartner Says a Green Data Centre Means More than Energy Efficiency” Egham, UK, October 20, 2008

What is to be Done?

End-user participation is key– The Green Grid www.thegreengrid.org

– SNIA Green Storage Initiative www.snia.org

– Climate Savers Computing Initiative www.climatesaverscomputing.org

For existing data centers– Verify the sizing and air flow integrity of your CRAC/HVAC systems

– Redesign rack placement for optimum cooling efficiency

– Equipment lifecycle / replacement should be energy-aware

– Select server, networking and storage products for optimum energy efficiency

For new data centers– Site selection should consider power sourcing as a priority

– Design collaboration between building architects and IT to maximize efficiency of

equipment placement



Organized Industry Responsesto the Pending Data Center Energy Crisis

The Green Grid – Charter includes power efficiency in the entire data center infrastructure

– Buildings, power sourcing, cooling, equipment density, equipment efficiency

– Defining metrics for data center efficiency

– More information at www.thegreengrid.org

SNIA Green Storage Networking Initiative– Focused on power efficiency in all aspects of storage networking

– Network infrastructure, storage, data lifecycle, data management

– Defining metrics for storage network efficiency

– More information at www.snia.org



End User and Business Alliance

Climate Savers Computing Initiative – Seeking to reduce computing energy consumption by half by 2010

– Saving the equivalent of 11 million cars or 10-20 coal-fired power plants

– More information at www.climatesaverscomputing.org



Brocade’s “Green” Initatives

�Best-in-class Power Efficiency: Power consumed per each

Gigabit

�Award winning products: Industry’s highest density, smaller

foot print => lower heating and cooling

�Enable “Pay-as-you-grow” architecture: Scaling on demand

�Optimal Power over Ethernet (PoE): Foundation for

converged applications and efficient power source

�Best data center practices: Propagate through training and

professional services

�Practice what we preach in our own facilities



Green InitiativesSmall steps can make BIG difference

– Replace 3 light bulbs for Compact Fluorescent bulbs

• Removes 300 pounds300 pounds of carbon dioxide per year from the air

– Turn off your big-screen TV – for every 6 hours per day it is on• It generates about 1,000 pounds1,000 pounds of carbon dioxide emissions per year

– Car pooling just two days per week• Reduces carbon dioxide emissions by 1,590 pounds1,590 pounds per year

– Setting the thermostat seasonally up or down 2 degrees at home• Saves about 2,000 pounds2,000 pounds of carbon dioxide yearly

– Use a Brocade 48000 Director rather than an alternative brand• Save 16,260 pounds16,260 pounds of carbon dioxide emissions per year per Director

– If 1% (one-percent) of car owners maintained their cars better• Would reduce carbon dioxide emissions by a Billion poundsa Billion pounds per year



What our customers are saying

“Choosing Brocade meant reduced costs, especially in terms of power

consumption. When we did power comparisons, the Brocade FastIron

Edge Series PoE was much more efficient for redundant power supplies.”

- Joe Granneman, CTO, Rockford Health Systems

Rockford Health Systems is the largest health systems serving northern

illinois and southern Wisconsin. With the help of Brocade’s solution

Rockford Health Systems was able to:

- Deliver the healthcare applications successfully

- Reduced costs with Lower power consumption

- More flexibility with shorter recovery time
