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

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.
