Early indicators of a rising ‘Green Business’ trend
January 2007: Marks and Spencer CEO Stuart Rose committedthe company to becomecarbon neutral and send
no waste to landfill by 2012.
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.

Virtualization
• The process of running two or more logical computer systems on
one set of hardware.
Server virtualization
• 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
Data Center ECS
monitoring/management Use of renewable offsets More efficient
UPS+generators Need to improve efficiency Rotary vs. cell
Better power monitoring
Server 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, 40 lbs/month.• The paper itself consumes 10x the energy of printing on it.• So the fix is print less measure and analyze document flows.• 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
storage.
• 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.
Reduce• Consume fewer servers, printers, so forth by
increasing utilization- virtualize.• Stop over provisioning; improve capacity planning.• Turn equipment off, turn power management on.
Reuse• Extend the life of assets by reusing them within the
enterprise and externally.
Recycle• 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.
Conclusion
• 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.
• The next wave of green IT: Broader change in processes, behavior, and company culture
The largest enterprise of all.. the
environment
