The Challenge
It’s not easy being green
The power bill alone sometimes doesn’t tell the whole story…

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.

Rightsizing the Infrastructure
Delivering 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

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

Green Initiatives
Small steps can make BIG difference
– Replace 3 light bulbs for Compact Fluorescent bulbs
• Removes 300 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 pounds of carbon dioxide emissions per year
– Car pooling just two days per week
• Reduces carbon dioxide emissions by 1,590 pounds per year
– Setting the thermostat seasonally up or down 2 degrees at home
• Saves about 2,000 pounds of carbon dioxide yearly
– Use a Brocade 48000 Director rather than an alternative brand
• Save 16,260 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 pounds per year

What our customers are saying
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
“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
