2. Why Care About Energy Efficiency?

 System requirements grow faster 1
than silicon and cooling technology 1993 1995 1997 1999 2001 2003 2005
 Pushing the limits
• Total system power Source: N. McKeown, Stanford University (Modified)
• Individual device power
• Cooling infrastructure

3. Service Providers Care!
Verizon Sets Energy Efficiency Standard
Verizon announced what it says are the
global telecom industry’s first energy- Typical 20,000 sqft Data Center
To help Japan to reduce by
efficiency standards, designed meet its Kyoto Protocol target,
Uses 8 Megawatts
NTT Group aims to reduce electric power consumption
20% the power consumed by new telecom-
related equipment starting 2010 to the level of 1990
by Jan. 1, 2009.
BT 21C 20,000 sqft Data Center
Uses 3.2 Megawatts

4. Why Care About Energy?
1. Electricity costs rose 88% in US since 2003 (US EIA data)
Energy has become a non-trivial OPEX item
2. Worldwide legislation changes
Energy efficiency and climate control
EMEA: reduce CO2 by 20% by 2020
UK: reduce CO2 by 20% by 2010
Japan: reduce CO2 to 6% under 1990 level by 2010
USA: no government goal yet (but likely to change)
3. Carriers and businesses are setting new targets
 Reduced energy consumption
 Reduced heat dissipation
 reduced space requirements (volume footprint)

5. What Does This Mean for Data Networking?
 Telecom facilities are power hogs
• Direct contributors to CO2 emission
• 2-3x collateral energy loss (conversion, cooling)
 Data networking is still a growth industry
• Global connectivity relies massively on routing and switching
and this dependency increases
• Significant increases in traffic are expected
• This should NOT result in higher OPEX
Vendors need to respond to the challenge

6. Standardization – Just Beginning
 First paper on the subject in late 2008
 Developed the Energy Consumption Rating (ECR) for Classes of
Networking Devices
 Energy Efficiency for Telecommunication Equipment
 Method for Measurement and Reporting for Routing and Ethernet
Switch Products
 International Organization for Energy Efficiency has Began
Preliminary Investigations

7. ECR Initiative – ECR Measurement

8. ATIS – TEER Measurement

9. Test Setup for Energy Efficiency Measurement
