23
Carbon Reduction Commitment
24
Carbon Reduction Commitment

Government aim to reduce greenhouse gas emission


80% reduction by 2050
Who is targeted?


ALL Companies using Half Hourly Metres
usage >6000MWhr in 2008

Will indirectly impact ~20000 UK companies

Companies will have to buy & sell allowances...
25
Carbon Reduction Commitment

Estimated cost of typical consumption v allowance

Penalties and bonuses will be awarded depending on
performance
26
Impact on the Data Centre

Data centres will be affected

Pressure to reduce power consumption
But also .......

Demand for increased capacity at same time

Additional penalties are more likely to be incurred

Even more financial motivation to save cost
27
Options for DC owners?

Consolidation & virtualisation?

YES – both will help but .......


CAPEX to invest will outstrip CRC penalties at some point
Cluster computing
 poor load balance & hot spots
 inefficient energy use
Additional actions will be required to prevent
acceleration of energy growth
28
Energy Efficient Ethernet
29
Energy Efficient Ethernet

New Task Group formed to study ways to improve power consumption
for Ethernet : “Energy Efficient Ethernet”

Idea: Idle Time of Ethernet is up to 90% = 90% waste of energy

“Reduce power when traffic goes down”

Down to 10% or even 0% of energy during idle time
30
Existing developments

10Gig standard already ‘accidentally’ includes some features to
improve energy efficiency:

Power Back Off


Originally a ANEXT mitigation technique
Short Reach Mode

Theoretical means of reducing energy consumption
31
Power Back Off
Long/Short Links
server
server
Long link
switch
Short link
Signal attenuates over cable length
High transmit power from near server induces
high level Alien NEXT on weakened signal
32
Power Back Off
Long/Short Links
server
server
Long link
switch
Short link
With Power Back Off
Transmit power reduced to a level where receive
signal is OK.
33
Short Reach Mode

86% of DC Server/switch links <30m

Less noise cancellation and power required

Echo, NEXT, and FEXT cancellers account
for ~ 40% of the chip power consumption

Coding elements account for ~ 25%

remaining 35% of the chip’s area is taken up
for the AFE
In links <30m signal is analysed and cancellers are switched off .
Better NEXT/FEXT means more cancellers can be switched off
Requires better quality cabling .......
34
Auto Negotiation

Existing function but new enhancements

Match link rate to utilisation

turns off PHY’s at lower speed

Estimated savings

1Gbps  100Mbps = 2-4 watt saving

2 watts x 8 NICs = 16 watts / server

x 1000 servers 16kw/hr
= 140 Mw/hrs
= £10k per year
35
Wake-on-LAN (WOL)

Industry tests show server uses 70% power when idle

WOL closes nearly all power during inactive periods

Only tiny level of residual ‘standby’ power required to escape
from hibernation
36
Summary

Demand for bandwidth will increase

Need to plan for 40G now

