Why Green IT?
•
•
•
•

Save Money
Save energy
Save in cooling
Reduce long term hardware spend
Reduce carbon emissions
Save space in server room and desktop
Avoid infrastructure upgrades
Who can do Green IT?
• Anyone in control of a computer/s and related
hardware
• System Administrators
• Equipment manufacturers
• Computer assemblers
• IT sales personnel
• IT project contract authors
• Project Managers
Measure consumption to find out how much you
save with efficiency changes
Single Power point meter ~ $40
Building power meter $100, 3 phase $150
Can I apply Green IT now?
• YES
• Turn on Screen and Hard disk power
management
• Turn on Sleep and / or Hibernation
management
• Shutdown computers at then end of each day
• This saves approximately 60% on power

Blade Computing
•
•
•
•
•
Cheaper than individual servers in bulk
Redundancies built in
Saves space
Can be used for virtual servers and /or support thin clients
E.g. 8 blades with 2 x quad processors == 64 CPU’s
8 blade enclosure 264mm tall (6 RU)
Dual processor blade with 2 disks
V Motion
Distributed Resource Scheduler
Move virtual machines and shut off physical server when resource needs are low
Automatically save 40% more power by having server switch off at night and weekends

Green Choices
Turn on Power Management
Set screensavers to None
Buy Energy Star rated computers
Use laptops instead of desktops as they typically
use less power
Turn off peripherals when not in use
Turn off power at power point to stop phantom
/ standby loads
Close unused applications
Turn off monitor when not in use
Measure your power consumption
Peripherals Control
• USB controlled power board (~$40)
• When computer turns on USB turns on power points
• This can power monitor, printer, speakers, scanner,
external USB storage etc.
• Peripheral power consumption when computer off
ZERO
Power Supplies (80 PLUS)
• The best power supplies now are up to 88%
efficient
• This means less waste heat from computers
• Saving up to 28% PC use of electricity
• Less maintenance calls related to heat issues
• Save 30% of related cooling costs
• Better power factor saves you even more

Thin Client Example
• Run 26-42 thin clients per 4
CPU server
• Full multimedia thin clients
available
• Can use wireless, Ethernet,
modem or 3G card for
connection
• Can also be used for VOIP
telephony
• Consume ~ 11 watts each
• No replacement cycle
• ~ 25 kb/s average

Component Selection Guidance
Power supply with 80% minimum efficiency at 20%, 50% and 100% load
Display in sleep mode in 15 minutes or less when idle
Processor in sleep mode in 30 minutes to less when idle
Network speed reduced from 1 Gbps to 100 Mbps or 10 Mbps when sleeping
Power Management from Desktop
Computer Sleep States S3 & S4
• When S3 or S4 level sleep state is enabled in
BIOS the computer power consumption goes
down to a few Watts
• S1 – Flush caches and stop processor
• S2 – S1 + power down processor
• S3 – Keep memory powered and power off
everything else possible. Quick to resume time
• S4 – Hibernate, memory to hard disk. Power
failure safe. Slower resume time
BIOS Checklist
Advanced Configuration and Power Interface
(ACPI) : Enabled
Smart Fan : Enabled
Suspend Mode : S3
Speed Step / Cool n quiet : Enabled
Motherboard defaults are getting better (needed
for Energy Stars)
Managed Power Management
Software
• Can shut down computer as required by group
policy
• Work can be saved before automated shutdown
• Reports on status of all computers and how
much power is being saved
• Can wake up computer for updates or start of
work day
• Save ~ $6700 per year for 100 desktops

Cooling Calculations
 There
is a direct relationship between energy
consumption and cooling requirements needed
(3 BTU capacity needed for every 1 Watt
electrical load)
 Choosing efficient servers / desktop PC /
notebooks / thin clients reduces the building
cooling needs
 This saves money in initial capital costs and
running costs
Other Processors
Intel Atom processor uses up to 4 Watts and
now is used on small laptops
Via Eden processors use from 2.5 to 7 watts and
require no fans which is good for embedded or
battery power
ARM processors are used in PDA’s, mobile
phones, media players and sections of consumer
electronics
Where is IT saving environment
now?
• Electronic banking, electronic receipts,
electronic pay slips, Intranets, Wikis, electronic
form handling, email instead of post, email
instead of fax, duplex printing, saving us from
repetitive tasks, decision support systems,
electronic commerce, instant messaging,
electronic magazines & newspapers, online
services such as email, document handling and
computer maintenance.
