Early indicators of a rising ‘Green Business’ trend
Marks and Spencer
CEO Stuart Rose committed
the company to become
carbon neutral and send
no waste to landfill by 2012 .
The Bad News:ICT Accounts for approximately .. 2% .. of global CO2 emissions
ICT’s global CO2 emissions
IT operations are challenged by operational issues
But this industry cloud has a Silver Lining
There are substantial
inefficiencies in the
technology and use behaviors
that can be readily addressed…
..IT can significantly
contribute to control and
reduce the 98% of CO2
emissions caused by other
activities and industries.
What percentage of energy actually does productive work?
Getting started with green IT
Update your hardware
Using energy-efficient hardware is a simple way to reduce your carbon footprint
If it’s not in use, turn it off
New technologies can help you switch off the lights—and other idle resources—automatically
Virtualize, virtualize, virtualize
Virtualization lets you get more done with less hardware, lowering your energy consumption
Straighten out your storage
Learn four techniques for using energy-hogging hard drives more efficiently
Consolidate data centers
Eliminating data centers or building new, “green” ones cuts power utilization dramatically
Optimize IT Energy use
Protecting and Backing up Data
High Availability and Virtualization
Managing Power Wisely
Designing Efficient Data Centers
IT transformation - Energy savings
Provide energy efficient technology and products for the Commonwealth such as Energy Star qualified computers, printers and monitors.
Reduce the costs of power and cooling through the consolidation and virtualization of the IT server infrastructure.
Promote environmental improvement by increasing levels of efficiency that ultimately reduce greenhouse gas emissions.
Audit compliance with “green” or “emissions” objectives, regulation and standards.
Work toward establishing an enterprise-wide awareness to staff the expected power
management settings requirements and best practices for energy conservation – Ensure that everyone understands their personal responsibility to do so.
The process of running
two or more logical
computer systems on
one set of hardware .
Virtualization one of the most effective tools for cost effective, greener computing.
Reduce the cost of power and cooling through the consolidation and virtualization of the IT server infrastructure.
$300 -$600 per year in energy savings for every server removed through virtualization based consolidation.
Virtualization helps a company/enterprise lower power and cooling consumption, by reducing the machines and servers it needs.
System activity display with power management
Top Data Centre challenges
Holistic Look at Data Center Impact Reduce IT Load
Consolidate & virtualize servers
Storage Area Network
Remove decommissioned servers from rack and power
Right sized servers
Dynamic power load management
Dynamically migrate workloads from underused servers to enable them to be shut down
Use a low-power state or shut down servers when not in use
Purchase Green Servers (energy star, RoHS, EPEAT)
Architectural/software choices that promote efficiency
Raise temperature in data center
“ Get our ducts in a row ” (step 1)
Bottom-to-top airflow (step 2)
Replace HVAC w/higher efficiency
Options for free cooling or reuse of heated air
Reduce Cooling Load
DC air pressure at 5% above
DC thermal analysis & leak detection
Use blanking panels
Reduce Power Distribution Losses
Use of renewable offsets
More efficient UPS+generators
Need to improve efficiency
Rotary vs. cell
Better power monitoring
More-efficient power supplies
Focus on fans/blowers
Electrical conversion at the server
Energy management software
Benefits of data centre
Pc/laptop power management
PCs, monitors account
for more than a third
of ICT power consumption
and CO2 emissions.
Sixty percent of PCs are
left on after hours.
So the fix is educate staff,
use a lower power state
such as stand by, for
PCs and monitors after hours.
Greening printers and printing
Average office worker
prints 1,000 pages/month,
The paper itself consumes
10x the energy of printing
So the fix is print less
measure and analyze
Consolidate the printers into
fewer, standard, low impact
that share the same consumables.
Greening the staff..
Save energy by encouraging staff to power down their equipment when not in use.
Embrace virtualization technologies (using IT environments more
efficiently) and explore the consolidation of data processing and
Dispose of your technologies in a sound and environmentally
friendly manner, and
Utilize technologies that allow staff to stay connected in remote
locations, participate in meetings without travel, and respond quickly during emergency situations.
Consume fewer servers, printers, so forth by increasing utilization- virtualize.
Stop over provisioning; improve capacity planning.
Turn equipment off, turn power management on.
Extend the life of assets by reusing them within the enterprise and externally.
Ensure and validate the correct disposition of all electronic equipment.
Buy recyclable products.
What does the future hold..?
Increased legislation, regulation and tax breaks — power consumption, hazardous substances and e-waste.
Energy management across the ICT infrastructure, creating a more dynamic sense-and-respond environment.
More-efficient and smarter cooling, UPS and power supplies in the data center and for client devices and so on.
Better power management at every level — processors, PCBs, systems, operating systems and applications.
Power consumption as a design criterion for software and energy profiling.
Green IT Approaches Span the Globe brings in to focus the steps to reduce the carbon footprint of information technology at every point in the lifecycle of their government systems, from purchase and production through usage and ultimate disposal.
