Moving forward – how CNS can assistThe normal starting position is to asses where your organization is today. Many OEM’s offer an assessment service but these are usually biased
to their products or solutions. CNS operates a best-of-breed and best-in-class model that will enable us to work with the best technology providers
in a blended solution. By using our DREAM (Define, Review, Engineer, Accelerate, Manage) methodology we can help you answer the burning
questions;
How can I reduce energy costs? How efficient is my Data Center? How can I harness my compute power?What are best practices? How do I measure my carbon footprint? What investment is required?What are easy wins? What are industry trends & timescales? What are my priorities?
In answering these questions we will ensure that you have considered all of the options available to you, the end state of various scenarios going
forward, the budgetary estimates in realizing the preferred options and the likely timelines. We can help you define ICT Governance for green ICT
and ensure mandatory or voluntary compliance with regulations and policies.
At a technology level we can host workshops that will enable you to consider the implications of specific initiatives such as virtualization, applications
hosting, etc. Helping you to answer the question ‘is this a viable option’ and what are the trade offs.
OEM’s will have many compliances for their products and organizations
Data Center Efficiency
Enterprises face repeated challenges posed by power, cooling and the complexities of managing their Data Centers effectively in the UAE. Data
Centers are highly energy intensive and consume 10 to 100 times more energy per square foot than a typical office building. Around 25% of the
total ICT carbon dioxide emissions across the globe are from Data Centers. New designs must be environment friendly and less power hungry by
using energy efficient microprocessors and servers. Current installations must be reducing the number of servers and storage devices in the Data
Center through virtualization, consolidation and technology refresh.
The Data Center is at the center of your organization, its design and operation should be given full consideration. Before designing a Data Center
a proper medium to long term design should be made of all its needs when it is working at full capacity and growth should be anticipated. Similarly
due care should be taken in designing the telecommunication, cabling, power and security systems. Data Center space is an expensive asset.
A properly designed, implemented and maintained Data Center improves operating efficiency, protects capital investments, ensures reliable
operations and helps maintain cost control.
Designs & Best Practices
Airflow management in & between cabinets and floorsThe dynamics of air cooling drives the
need for better design of air conditioning
systems inside Data Centers. Below the
tile air conditioning airflow gets blocked
with power, cables and water pipes. High
density computing requires more airflow at
the component level so traditional peripheral
cooling designs become inefficient as larger
fans are required to
get cool air to the
cabinets.
Exhausting hot air from the cabinets will increase the effiency of the Data Center.
Air flow is a key Data Center design requirement.
Managed density recognizes that there really
is a limit to the number of cable terminations
and servers that can safely and economically
be housed in cabinets. A prime issue is
potential blocking of airflow caused by too
many cables within the cabinet. A solution
is to limit the number of servers and cable
terminations in a cabinet, especially copper
racks where the cable diameter is larger.
Another is to employ basic cable management
within the cabinet, such as securing cables
along the entire length of vertical cable
managers to open air flow. Moving cables
into an overhead raceway also improves the
airflow.
Hot Aisle/Cold Aisle Design
The traditional design for a raised floor area
effectively manages airflow and temperature
by keeping hot aisles hot and cold aisles
cold. The main issue with such a design
is that the complete Data Center is cooled
regardless of occupancy. The cost can be
reduced by increasing the temperature in the
cold aisle but the danger of hazardous hot
spots increase. Where high density blades
and servers are deployed a contained
cooling system is more efficient (typically
100% vs 95%).
Contained coolingThermal containment products maximize the effectiveness of
cooling solutions for low to high density racked ICT loads. Available
in rack or aisle level configurations, these products are designed
to completely separate the supply and return air paths of the ICT
equipment. Ideal for any ICT environment, the air separation
ensures the warmest possible air is being returned to the cooling
units, which further increases the efficiency, effectiveness,
capacity, and predictability of the cooling system.

A Practical Guide On How To Reduce Your ICT Energy Cost, Your Organization’s Carbon Footprint & Save Money
AS AN ICT MANAGER YOU ARE RESPONSIBLE FOR YOUR ORGANIZATIONS ICT INFRASTRUCTURE. THIS WILL INCLUDE A DIRECT RESPONSIBILITY FOR REDUCING ENERGY COSTS AND CONTRIBUTING TO REDUCING YOUR ORGANIZATIONS CARBON FOOTPRINT. CNS WILL HELP YOU ACHIEVE THIS IN-LINE WITH THE GLOBAL AND UAE FOCUS ON ENERGY & ENVIRONMENTAL MANGEMENT THAT IS REQUIRED TO SUSTAIN A MODERN AND GROWING ECONOMY THAT IS LEADING THE WAY IN ENVIRONMENTAL MANAGEMENT.
IRENAThe International Renewable Energy Agency (IRENA) was officially established in Bonn Germany, on 26 January 2009. The IRENA headquarters
will be located in Masdar City, Abu Dhabi, UAE. Masdar City will be the world's first carbon-neutral, zero waste city completely powered by
renewable energy.
Corporate and social responsibilityOne of the greatest threats to our future society and economy is global warming. It is estimated that the CO2 emissions of the ICT industry alone
exceeds the carbon output of the entire aviation industry. The ICT industry has a collective responsibility to help address this problem. Fortunately
we have the tools at hand to reduce energy consumption, reduce our dependence on non sustainable fuel sources and to reduce CO2 output to
zero. The UAE is a leader in setting and implementing environmental policies and guidelines at federal and government agency level.
Zero carbon & energy efficiency – the futureThe next generation green Data Centers are being built close to sustainable non fossil based fuel
sources such as hydro electricity or solar power. Forward thinking companies such as Google,
Microsoft and eBay are already planning or making moves to such zero carbon sites in remote
locations. There are some powerful economic incentives to do this in an era of skyrocketing and
unpredictable energy costs. With the Data Center close to the power source the cost of power
distribution is reduced to almost zero. Location of remote Data Centers is possible as data
communications can be delivered via optical cables and WAN’s.
This drives the concept of applications hosting rather than having your own Data Center. The
Data Center is the major consumer of power for both the facilities (cooling, power conditioning,
etc.) and ICT infrastructure (servers, storage, etc.). Applications-On-Demand via giga Data
Centers will continue to emerge as the main source of ICT delivery. The raw compute power and
storage required is more efficiently delivered in this way.
Today’s choices – Data CenterThe Data Center is the area of priority. If you have an existing operation how can you be more efficient, compliant or better positioned to reduce
energy costs and support environmental policies? If you are considering building a new Data Center or architecting a new ICT infrastructure what
are the best practices, the best products and best designs? The choices are many, but they will require investment and possibly a write off of
current assets. These options are detailed:
Consolidate your current infrastructure – An approach
to more efficient usage of server resources is to reduce the total
number of servers or server locations that an organization requires.
Under-utilized servers take up more space and consume more
power than can be justified. Although consolidation can substantially
increase the efficient use of server resources, it may also result in
complex configurations of data, applications, and servers that can
be confusing for the average user to contend with. To alleviate this
problem, virtualization may be used to mask the details of server
resources from users while optimizing resource sharing.
Refresh your current infrastructure – Many OEM’s offer
incentives to replace your old servers with new (often taking back
the old ones for recycling). These new servers will have the latest
energy efficiencies built in. Look for efficiencies via variable speed
fans, lower power consumption CPU’s, greater performance per watt
devices, etc.
Re-engineer – New developments in cooling solutions mean
that it is possible to create ‘Data Centers within Data Centers’
with containment systems that are ideal for high density server
solutions. Returning the warmest possible air to the computer room
air conditioners increases the efficiency and capacity of the system.
A hot aisle containment system ensures proper air distribution by
completely separating supply and return air paths. The hot aisle is
sealed off using doors and transparent ceiling tiles that extend the
width of the hot aisle. Such solutions will require the appropriate
cooling systems.
Chilled water – In the UAE local chilled water supplies from
organizations such as Tabreed and Empower allow central services
to be used. This is a more efficient solution where such utility supplies
are available. You may also use your own building chilled water supply
if available. Where chilled water is not yet available select gas chilled
CCU’s that can operate on chilled water for future requirements.
Hosting – It is possible to move your servers and storage to a
hosted Data Center that should provide a more efficient environment
but only if they are well designed and managed. The objective is to
leverage the facilities that they provide. Alternatively it is possible to
simply run your applications on the actual ICT infrastructure that the
hosting company offers, typically using blades and virtualization for
scalability and manageability.
Managing you assets is a key requirement.
Today’s choices – OfficeFor most organizations a major part of the ICT
infrastructure is located on the desk top or in
local equipment rooms. These systems are
also a major source of energy consumption
and savings can be made by taking the
following initiatives:
Life span management – does your
organization know what devices it has? What
they are used for? How old are they? How
compatible they are? How they perform? Are
they being underutilized? etc. It is possible
to install enterprise wide asset management
systems that will enable you to answer these
questions. This should be supported by
an effective technology refresh program to
replace obsolete devices.
Thin client – It is possible to reduce the
power of desk top devices by implementing
a thin client infrastructure where the devices
can be low spec or terminal based devices.
This will reduce the power at the desk top
and increase the efficiency of the servers that
will manage the applications.
Power management - Reducing the
energy consumption of computers and
monitors is simple and it does not always
require investing in newer models. Turning
computers off at night or putting them into low
power mode when they are idle can reduce
their annual energy consumption by more
than half. Power management can be done
manually or automatically.
Manual power management requires users
to physically turn off their computer or put
it into low power mode. As such, it requires
an education program. Automatic power
management (either by properly configuring
any built in power management features, or
using third party software) can theoretically
ensure 100% of computers are turned off at
night or in low power mode when idle.
“The Total Cost Of Powering And Cooling A Data Center May Outstrip The Capital Cost Of The Equipment Itself.”
Managed Green ICTLeverage!CNS is a Managed Services solution
that provides an a la carte based approach for
you to gain access to the resources and skills
required, as and how you want. With over 20
years of experience in the UAE we have a
team of ICT support strategists, implementers,
engineers and managers, ready to assist
you when and where required.
There are 11 options, Managed
Environment is one.
Managed EnvironmentThe drive for ‘green ICT’ is being
accelerated as legislation evolves
and energy costs increase. This
applies as much to the UAE as any other
country. CNS will help you develop an
environmental policy for your ICT infrastructure
that will embrace a number of key areas
ranging from selection of environmentally
friendly products (RoHS, low power, etc.),
architecting a more efficient ICT solution
(virtualization, consolidation, etc.), designing
energy efficient Data Centers
(exploiting optical data storage,
chilled water CCU’s, variable
speed fans, high efficiency UPS’s,
etc), reducing consumption of
consumables; and implementing
energy saving software solutions
and best practices.
Such initiatives can be achieved along with
more basic actions such as; equipment
disposal; recycling of paper and packaging;
intelligent low power lighting; sponsorships
of environmental projects; choice of suppliers
and materials; modes of transport (sea versus
air); building insulation; staff travel times and
modes; etc. CNS will be able to create for you
an environmental policy that demonstrates your
organization’s concerns and compliances.
Blades vs ServersThere is some contention over whether deploying rackable servers
is better than deploying blade servers to host consolidated or
virtualized applications. Although true blade servers do present
density and capacity concerns for older Data Centers, these
concerns are distinct from concerns about the efficiency of electrical
consumption.
Where the concept of green is concerned, efficiency
is the focus. More effective use of existing power
supply corresponds to fewer emissions resulting
from fossil fueled power generation. In this scenario
blade designs are good. Blade form factors per work
unit performed consume power and cooling more
efficiently than do standalone rack mounted servers.
As efficiency is in part a cumulative calculation of
how a disparate ICT infrastructure interoperates
with supporting facilities, blade capacity and density
requirements must be designed to achieve maximum
efficiency benefits. In most cases, this requirement often necessitates
building a new Data Center to support higher densities, mainly
because of the cost of upgrading the existing facilities infrastructure
(power distribution, cooling, floor design, etc.)
Virtualization - The acceleration of server virtualization, in
particular, has started to transform the way organizations deliver
applications to end users, enabling organizations to build dynamic
pools of compute power that can be allocated on demand
as business needs change. Many organizations that
used to run dozens of applications on dozens of servers
have been able to consolidate down to just a handful
of virtualized servers, each capable of running multiple
applications on multiple operating systems.
Virtualization of storage helps achieve location
independence by abstracting the physical location of
the data. The Virtualization system presents to the user
a logical space for data storage and itself handles the
process of mapping it to the actual physical location.
Server ProblemsServers in most Data Centers today have been designed for performance and cost optimization,
not energy efficiency. With some companies finding up to 40% of their operational costs going
to providing power and cooling to these systems, the cost of energy over the server’s life can be
more than the purchase price of the servers. Inefficiencies fall into several areas, including power
conversion, utilization, and systems management.
Many servers in Data Centers today have power supplies that are only 70% efficient. This means
that 30% of the power going to the server is simply lost as heat. Having inefficient power supplies
means that excess money is being spent on power with additional cooling needed as well. Another problem with current servers is that they are
used at only 15% of their capacity. A problem from a power and cooling perspective is that the amount of power required to run traditional servers
does not vary linearly with the utilization of the server. That is, ten servers running each at 10% utilization will consume much more power than
one or two servers that each run at 80-90% utilization.
A lack of effective power management is often a problem with many existing systems. Future designs will allow power to be scaled back if
the systems did not need the power. However, many of the existing systems do not have the ability to change the voltage or frequency of the
processors, and often cannot even give the ICT manager insight into actual system power consumption.
An economic crisis exacerbates Data Center issues. Most ICT managers are finding that they have little or no money available for investment,
without the ability to show hard return on investment (ROI). In contrast to the increase in cost of energy is the reduction in the cost of real estate
and the lack of hosting facilities which pushes such costs up.
PUE is a KPI for all Data Centers
LEED Certification Criteria Leadership in energy and Environmental Design (LEED) was developed to
promote development of facilities that are environmentally responsible.
ICT Energy efficiency is a major component toward
LEED certification. In general, LEED buildings:
• Have lower operating costs
• Are healthier for occupants
• Conserve water and energy
• Offer increased asset value

air conditioners increases the efficiency and capacity of the system.
A hot aisle containment system ensures proper air distribution by
completely separating supply and return air paths. The hot aisle is
sealed off using doors and transparent ceiling tiles that extend the
width of the hot aisle. Such solutions will require the appropriate
cooling systems.
Chilled water – In the UAE local chilled water supplies from
organizations such as Tabreed and Empower allow central services
to be used. This is a more efficient solution where such utility supplies
are available. You may also use your own building chilled water supply
if available. Where chilled water is not yet available select gas chilled
CCU’s that can operate on chilled water for future requirements.
Hosting – It is possible to move your servers and storage to a
hosted Data Center that should provide a more efficient environment
but only if they are well designed and managed. The objective is to
leverage the facilities that they provide. Alternatively it is possible to
simply run your applications on the actual ICT infrastructure that the
hosting company offers, typically using blades and virtualization for
scalability and manageability.
Managing you assets is a key requirement.
Today’s choices – OfficeFor most organizations a major part of the ICT
infrastructure is located on the desk top or in
local equipment rooms. These systems are
also a major source of energy consumption
and savings can be made by taking the
following initiatives:
Life span management – does your
organization know what devices it has? What
they are used for? How old are they? How
compatible they are? How they perform? Are
they being underutilized? etc. It is possible
to install enterprise wide asset management
systems that will enable you to answer these
questions. This should be supported by
an effective technology refresh program to
replace obsolete devices.
Thin client – It is possible to reduce the
power of desk top devices by implementing
a thin client infrastructure where the devices
can be low spec or terminal based devices.
This will reduce the power at the desk top
and increase the efficiency of the servers that
will manage the applications.
Power management - Reducing the
energy consumption of computers and
monitors is simple and it does not always
require investing in newer models. Turning
computers off at night or putting them into low
power mode when they are idle can reduce
their annual energy consumption by more
than half. Power management can be done
manually or automatically.
Manual power management requires users
to physically turn off their computer or put
it into low power mode. As such, it requires
an education program. Automatic power
management (either by properly configuring
any built in power management features, or
using third party software) can theoretically
ensure 100% of computers are turned off at
night or in low power mode when idle.
“The Total Cost Of Powering And Cooling A Data Center May Outstrip The Capital Cost Of The Equipment Itself.”
Managed Green ICTLeverage!CNS is a Managed Services solution
that provides an a la carte based approach for
you to gain access to the resources and skills
required, as and how you want. With over 20
years of experience in the UAE we have a
team of ICT support strategists, implementers,
engineers and managers, ready to assist
you when and where required.
There are 11 options, Managed
Environment is one.
Managed EnvironmentThe drive for ‘green ICT’ is being
accelerated as legislation evolves
and energy costs increase. This
applies as much to the UAE as any other
country. CNS will help you develop an
environmental policy for your ICT infrastructure
that will embrace a number of key areas
ranging from selection of environmentally
friendly products (RoHS, low power, etc.),
architecting a more efficient ICT solution
(virtualization, consolidation, etc.), designing
energy efficient Data Centers
(exploiting optical data storage,
chilled water CCU’s, variable
speed fans, high efficiency UPS’s,
etc), reducing consumption of
consumables; and implementing
energy saving software solutions
and best practices.
Such initiatives can be achieved along with
more basic actions such as; equipment
disposal; recycling of paper and packaging;
intelligent low power lighting; sponsorships
of environmental projects; choice of suppliers
and materials; modes of transport (sea versus
air); building insulation; staff travel times and
modes; etc. CNS will be able to create for you
an environmental policy that demonstrates your
organization’s concerns and compliances.
Blades vs ServersThere is some contention over whether deploying rackable servers
is better than deploying blade servers to host consolidated or
virtualized applications. Although true blade servers do present
density and capacity concerns for older Data Centers, these
concerns are distinct from concerns about the efficiency of electrical
consumption.
Where the concept of green is concerned, efficiency
is the focus. More effective use of existing power
supply corresponds to fewer emissions resulting
from fossil fueled power generation. In this scenario
blade designs are good. Blade form factors per work
unit performed consume power and cooling more
efficiently than do standalone rack mounted servers.
As efficiency is in part a cumulative calculation of
how a disparate ICT infrastructure interoperates
with supporting facilities, blade capacity and density
requirements must be designed to achieve maximum
efficiency benefits. In most cases, this requirement often necessitates
building a new Data Center to support higher densities, mainly
because of the cost of upgrading the existing facilities infrastructure
(power distribution, cooling, floor design, etc.)
Virtualization - The acceleration of server virtualization, in
particular, has started to transform the way organizations deliver
applications to end users, enabling organizations to build dynamic
pools of compute power that can be allocated on demand
as business needs change. Many organizations that
used to run dozens of applications on dozens of servers
have been able to consolidate down to just a handful
of virtualized servers, each capable of running multiple
applications on multiple operating systems.
Virtualization of storage helps achieve location
independence by abstracting the physical location of
the data. The Virtualization system presents to the user
a logical space for data storage and itself handles the
process of mapping it to the actual physical location.
Server ProblemsServers in most Data Centers today have been designed for performance and cost optimization,
not energy efficiency. With some companies finding up to 40% of their operational costs going
to providing power and cooling to these systems, the cost of energy over the server’s life can be
more than the purchase price of the servers. Inefficiencies fall into several areas, including power
conversion, utilization, and systems management.
Many servers in Data Centers today have power supplies that are only 70% efficient. This means
that 30% of the power going to the server is simply lost as heat. Having inefficient power supplies
means that excess money is being spent on power with additional cooling needed as well. Another problem with current servers is that they are
used at only 15% of their capacity. A problem from a power and cooling perspective is that the amount of power required to run traditional servers
does not vary linearly with the utilization of the server. That is, ten servers running each at 10% utilization will consume much more power than
one or two servers that each run at 80-90% utilization.
A lack of effective power management is often a problem with many existing systems. Future designs will allow power to be scaled back if
the systems did not need the power. However, many of the existing systems do not have the ability to change the voltage or frequency of the
processors, and often cannot even give the ICT manager insight into actual system power consumption.
An economic crisis exacerbates Data Center issues. Most ICT managers are finding that they have little or no money available for investment,
without the ability to show hard return on investment (ROI). In contrast to the increase in cost of energy is the reduction in the cost of real estate
and the lack of hosting facilities which pushes such costs up.
PUE is a KPI for all Data Centers
LEED Certification Criteria Leadership in energy and Environmental Design (LEED) was developed to
promote development of facilities that are environmentally responsible.
ICT Energy efficiency is a major component toward
LEED certification. In general, LEED buildings:
• Have lower operating costs
• Are healthier for occupants
• Conserve water and energy
• Offer increased asset value

Data Center Efficiency
Enterprises face repeated challenges posed by power, cooling and the complexities of managing their Data Centers effectively in the UAE. Data
Centers are highly energy intensive and consume 10 to 100 times more energy per square foot than a typical office building. Around 25% of the
total ICT carbon dioxide emissions across the globe are from Data Centers. New designs must be environment friendly and less power hungry by
using energy efficient microprocessors and servers. Current installations must be reducing the number of servers and storage devices in the Data
Center through virtualization, consolidation and technology refresh.
The Data Center is at the center of your organization, its design and operation should be given full consideration. Before designing a Data Center
a proper medium to long term design should be made of all its needs when it is working at full capacity and growth should be anticipated. Similarly
due care should be taken in designing the telecommunication, cabling, power and security systems. Data Center space is an expensive asset.
A properly designed, implemented and maintained Data Center improves operating efficiency, protects capital investments, ensures reliable
operations and helps maintain cost control.
Designs & Best Practices
Airflow management in & between cabinets and floorsThe dynamics of air cooling drives the
need for better design of air conditioning
systems inside Data Centers. Below the
tile air conditioning airflow gets blocked
with power, cables and water pipes. High
density computing requires more airflow at
the component level so traditional peripheral
cooling designs become inefficient as larger
fans are required to
get cool air to the
cabinets.
Exhausting hot air from the cabinets will increase the effiency of the Data Center.
Air flow is a key Data Center design requirement.
Managed density recognizes that there really
is a limit to the number of cable terminations
and servers that can safely and economically
be housed in cabinets. A prime issue is
potential blocking of airflow caused by too
many cables within the cabinet. A solution
is to limit the number of servers and cable
terminations in a cabinet, especially copper
racks where the cable diameter is larger.
Another is to employ basic cable management
within the cabinet, such as securing cables
along the entire length of vertical cable
managers to open air flow. Moving cables
into an overhead raceway also improves the
airflow.
Hot Aisle/Cold Aisle Design
The traditional design for a raised floor area
effectively manages airflow and temperature
by keeping hot aisles hot and cold aisles
cold. The main issue with such a design
is that the complete Data Center is cooled
regardless of occupancy. The cost can be
reduced by increasing the temperature in the
cold aisle but the danger of hazardous hot
spots increase. Where high density blades
and servers are deployed a contained
cooling system is more efficient (typically
100% vs 95%).
Contained coolingThermal containment products maximize the effectiveness of
cooling solutions for low to high density racked ICT loads. Available
in rack or aisle level configurations, these products are designed
to completely separate the supply and return air paths of the ICT
equipment. Ideal for any ICT environment, the air separation
ensures the warmest possible air is being returned to the cooling
units, which further increases the efficiency, effectiveness,
capacity, and predictability of the cooling system.
