Agenda
• How Big Is The Problem
• Easy Savings
• Data Center Virtualization
• Equipment Refresh
Opportunities
• Wireless LAN
• IP Telephony
• LAN Refresh
• Power It Down
Rising Energy Consumption in the Data Center
Go Green
• Reduce hazardous waste
• Reduce global warming
• Reduce carbon footprint
• Reduce energy consumption
• Reduce cost of operations
What Are Organizations Focusing On
Energy Reductions
• Power down power strips at night
• Upgrade to newer, more efficient UPS 97% vs.
70%-80%
• Switch to networked laser printers
• Implement fax server
• Refresh more energy efficient PCs -> Laptops
• Reduce travel with video conferencing
• Raise the temperature in the data center
Virtualize Servers and Storage
• Virtualizing servers and storage can
drastically reduce
– Power Consumption
– Carbon Emissions
– Cap-Ex Costs
– Op-Ex Costs
How Big Is The Problem
•
According to the EPA, servers consume 40% of total datacenter power
consumption.
•
Site infrastructure—including cooling of equipment—accounts for another 50
percent of total datacenter power consumption.
•
x86 servers typically house only a single application, their processors sit idle 85-95
percent of the time. While sitting idle, these servers use nearly as much power as
they do when they are active.
•
Hardware capacity is typically over-provisioned for peak loads because it is hard
to adjust dynamically. The result is too much hardware that is highly inefficient at
delivering IT services
•
According to analysts, companies maintain roughly three years of excess
hardware capacity due to this vast underutilization. With more than seven million
servers sold annually, this represents more than 20 million servers sitting idle and
wasting energy
Server Consolidation
• Virtualization technology allows organizations to run
multiple application and OS workloads on the same
server.
– Ten server workloads running on a single physical server is
typical.
– Some organizations are consolidating as many as 30 or 40
workloads onto one server.
– Utilization of x86 servers increases from the typical 8-15
percent to 70-80 percent.
– Reducing the number of physical servers through
virtualization cuts power and cooling costs and provides
more computing power in less space. As a result, energy
consumption typically decreases by 80 percent
Environmental Impact of
Virtualization
• Every server that is virtualized saves 7,000 kWh
of electricity.
• Every server virtualized is equivalent to removing
4 tons of carbon dioxide (CO2)from the
environment or taking 1.5 cars off the road
annually.
• Green your IT infrastructure while improving
reliability, availability and service levels.
Equipment Refresh
• Less is More
– Devices
– Wattage
• The cooling multiplier:
– It is estimated that every $1 on power
requires another $2 on cooling!
• Newer = More efficient

• < 800W Power Usage
• > 2000W Power Usage
IP Telephony Refresh Savings
• Old TDM systems are big power hungry boxes
• IPT systems use existing switch infrastructure
and software running on server
PoE Competitive Summary
• Look for Phone models that are the most power efficient:
–Class 2 = 3.84W to 6.49W
–Class 3 = up to 12.95W
• Low power phone advantages:
–Requires less A/C power within building or facility
–Requires less air conditioning / cooling in switch rooms and
wiring closets
LAN Refresh Savings
• Use 2 Tier Network Architecture Instead of 3 Tier Where Possible
►High density switches enable eliminating layers
►Many mid-Enterprise networks moving to 2-tier instead of 3-tier
• Focus on Energy Efficient Switches
• Efficient Power Supplies
• Variable Speed Fans
• OS with energy saving features
Power It Down

School District – Summer Vacation
Assume 25 school buildings K-12
Assume 50 desk phones per school – 1,250
phones total
Very light utilization
during the summer months
