Green-IT
What do we mean with Green-IT Lowering CO2 footprint or…lowering cost of power usage = €
But Green-IT should also be about… Selecting suppliers which use production processes that have a lower
environmental impact Selecting companies providing solutions to destroy old equipment in
an ecological way Lowering the use of waste products like toner, paper,… Selecting hardware which contains materials that are easier to process
in an environmentally responsible way
Green-IT
General consideration
Evaluating the first order impact of quick wins is important but the second order impact is just as important and accounts for the biggest part in the end-to-end evaluation
E.g. moving from laser printers to inkjet printers will lower the electrical consumption … but paper printed with inkjet requires more energy for recycling
EU and Carbon footprint cost
Near future (<3 years) No intention from EU to charge companies for their kWh usage or CO2
footprint (feedback Gartner) However the Green Grid members expect companies to be fined for their
CO2 footprint starting from 2010 The EU code of conduct is a start
The EU launched a “code of conduct” for datacenters. Goal: provide guidelines to reduce datacenter energy usage ( aim for 20% to
30% reduction) Voluntary program Will it stay voluntary ?
Mid/Long term future Risk of being charged for the carbon footprint ?
• E.g. 20 – 30 € / ton CO2
One word … so many questions
Source: Data Center Operations Council research
Internal KBC Questionnaire
1. Is electrical usage a selection criteria when selecting new equipment?
2. What do you do to lower the electrical consumption? 3. Do we check if suppliers have a corporate environmental or
social responsibility charter? 4. Do we score them on their production processes? 5. Do we check how equipment is being recycled? 6. How important is the usage of environmental friendly
material in our hardware? 7. Is the reduction of our environmental footprint included in
the roadmap?
Feedback Mainframe
IBM promotes his newest generation of mainframes as Green technology…however the total power usage doesn’t go down. It can simply host more applications = less other hardware = more energy efficient
But more applications on mainframe equals risk for vendor lock-in -> a preferred situation ?
The total energy usage of the mainframe can be limited (= power capping) but this only done specifically to manage the mainframe cost and not to lower the energy cost
Feedback Storage
Hard disk technology can have an impact on the total power consumption
Store static data on low end hard disks.
A technology like complete spin down could reduce the power usage to zero. However at the same time this could have an impact on performance and availability
Feedback Telecom
No real initiatives to lower the total power consumption ; power criteria are not part of RFI/RFP processes
There are some thoughts on joining the access-, distribution- & core layer but questions on the technical impact
Scanning usage of network ports is already integrated but results are in some cases difficult to interpret. No line activity doesn’t automatically mean that the system is ghost
hardware -> e.g. acceptance servers
Feedback Telecom
VoIP project did not take electrical consumption into account
SIEMON white paper on copper and fiber standards Talks about power benefits when selecting higher rated cabling. In general the quality of cabling reduces noise signals which in return
lowers power usage on switch ports since there is no need for compensation
This approach is confirmed by other cabling suppliers
Feedback Servers

Feedback Desktop
Desktop virtualization Requires a lot of centralized blade servers in the datacenters to host all the
applications Desktops will be thin clients that depend heavily on the calculating power of
the central servers. Power usage of these thin clients is very low (around 10W)
MEA Master Thesis of Tom Samyn shows a very positive business case with short ROI (2.5 years) but …
The implementation of desktop virtualization is impacting the complete IT infrastructure, causing a lot of dependencies to manage. The most challenging risks are on product maturity. Currently there are no industry standards on desktop virtualization technology, which results in the fact that this technology is likely not to be considered as mainstream until 2011.
Feedback Desktop
The pre-study “Wake on LAN” showed that technical limitations prevented applying hibernation
• It was impossible to use “wake on LAN” features on desktops in hibernation mode.
• Some client/server applications showed defects during transition from power on to hibernation mode -> increase of incident requests
• Hibernation requires extra disk space• Wake on LAN was possible on desktops in stand-by mode but the difference in
power usage between a desktop in operational mode and one stand by mode was only minor
Currently it is not possible to completely shut down all desktops and apply all (meaning critical security patches & software installations) patches on one specific moment. All security patches are applied during the night. Sometimes these security patches are to critical to delay them to a later date.
Feedback Desktop
However ICT organizations are currently investigating the Intel vPro processor which enables remote access to a desktops independent of the state of the operating system.
• V-PRO would probably have a success rate of 100%• However it requires a lot of extra hardware• High CREATE & maintenance cost
This new technology requires further investigation before it can be put into effect.
Feedback Messaging & Collaboration
Global labor distribution forces the need to connect dispersed work force
Expense cuts force the need to displace business travel
Therefore KBC implements a roadmap for Messaging and Collaboration together with BT , based on IBM technology
Focus on mail, presence awareness, instant messaging, webconferencing, virtual places.
General results
Green IT is not the main driver of our roadmap because…
Technology is still the main driver No Green-IT framework Selecting hardware which consumes less power could have impact
performance and availability It is not always clear what the “€” profit will be against the cost
introduced to provide Green-IT solutions There is no driver since IT departments are not invoiced individually
for the power usage of their equipment
