Six Data Center
Trends
At Emerson Network Power, we’re blessed with a large (and
lively) group of passionate data center customers and internal
experts from around the world. We asked these folks to reflect
on their experiences and give us some predictions/trends for the
coming year.
We collated the responses, destroyed the names to protect the
guilty, and looked for common themes. In the end, six strong
themes emerged:
1. Cloud comes of age
Certainly the term “cloud” is nothing new: Most organizations
already use some form of software-as-a-service (SaaS), and
many have adopted cloud (or at least “cloud-like”) infrastructure
components in their environments. Now cloud is poised to expand
from that foothold and become an engine of innovation, with
cloud providers driving that innovation as they adopt technologies,
business models and practices that achieve high reliability and
application mobility at the lowest possible cost.
2. Integration extends its reach
With rapid changes in many markets being driven by innovation,
digitization and mobility, the need for speed that integration and
convergence delivers is greater than ever. As a result, integration
and convergence have expanded beyond the IT stack to the
systems that support that stack. In this new environment, any space
becomes a self-maintaining computing space, and entire data center
facilities are now being designed and constructed from integrated,
prefabricated modules.

5. The edge gets stronger
After years of consolidation and centralization, IT
organizations are turning their attention to the edge of
the network to improve interactions with customers and
applications. As organizations grow their use of analytics,
location-based services, and personalized content, edge
of network facilities will become critical in achieving
competitive advantage.
6. Security becomes the new availability
3. Convergence goes macro
Technology systems aren’t the only things experiencing a
convergence. The telecommunications and IT industries are
moving closer together as voice and data services are now
routinely consumed on the same device. This convergence
will drive more standardization in the technologies used to
support voice and data services and break down the silos
that have traditionally existed between these two critical
functions.
4. Software paves the way for more
software
Virtualization marked one of the most significant trends
in the data center industry in the last twenty years. The
impact of this development will continue to drive change
for the foreseeable future as virtualization extends beyond
computing to networking and storage. An interesting
paradox begins to develop where application development
and deployment gets much easier and faster, while
understanding the underlying physical environment
and dependencies becomes harder. One of the key
challenges in this virtual revolution is going to be hardware
management.

While downtime is still a risk for data center managers,
a new threat has emerged in the form of cyber security.
Increasingly, data center and facility managers will
have to work with their IT security teams to audit the
technology and software of infrastructure equipment to
ensure security and evaluate the security practices of the
contractors and service providers that have access to that
equipment.
So what does all of this mean? In the past we’ve all
experienced technology changes within the data center,
but now the very concept of what is a data center is
changing as well. Virtualization and edge computing are
erasing walls, hybrid clouds and telecom/IT convergence
are challenging models, and more complex infrastructure
management and security challenges are causing
nightmares. We’re probably due for a more holistic,
intelligent and integrated approach to data center design
and operation, which results in a new generation of facilities
that make more effective use of capital, can respond
faster to changing requirements, and that enable simpler
management and more accurate forecasting.

merson Network Power asked Forrester
Consulting to compile a Financial Impact
study of Emerson’s Data Center Infrastructure
Management solution, Trellis™ Platform.
The researchers spoke to a global financial
institution customer and what they identified
was a clear opportunity to improve availability and
increase efficiency.
The analysis showed that in a three-year period the
institution gained more than $1.6 million in benefit,
and recouped its investment in just 13 months.
The main contributors to these results were improved
system availability for customer-facing systems,
greater productivity of remote management,
enhanced capacity planning, and reduced energy
consumption.
More specifically, the bank cut unscheduled downtime
by 20 hours annually across its three data centers,
reduced power consumption and related energy
costs, consolidated 19 servers, and were able to delay
construction of a new data center.

Rapid Deployment of T-Systems’
Strategic Modular Data Center
and transformation program and allows us
to provide cloud services across Europe,”
stated Raúl Saura, Head of Dynamic
Platform Services at T-Systems Iberia.
“To timely achieve strategic goals, it was
critical to quickly deploy a state-of-theart, Tier III, twincore data center.”
Traditional or Modular?
“We were evaluating several options like
collocation, brick and mortar construction
and modular containerized construction.
After crunching facts and figures, we
valued the modular construction to be the
most efficient solution for Barcelona under
all aspects, from overall lead time and costs
to specific infrastructure parameters.”
explained Sven Meyer, Group Procurement
for Deutsche Telekom.
T-Systems selected
Emerson Network
Power to deliver its
state-of-the-art,
Tier III modular
data center.
A global IT services and consulting
company founded in 2000 as a subsidiary
of Deutsche Telekom, T-Systems is one of
the largest European IT service companies
with global delivery capabilities. With
headquarters in Frankfurt, T-Systems
provides integrated solutions for
multinational corporations and public
sector institutions. With end-to-end IT
and telecommunications solutions and its
dedicated innovation management team,
T-Systems positions itself as an innovative
leader in the IT field.
Following its new strategic vision to
provide cloud services, the company’s
6
Spring 2015
need for data center expansion became
paramount. To fulfil T-Systems’
expectations and meet their clients’
business cases, a combination of
requirements needed to be achieved for
availability, reliability, security, scalability,
transparency, efficiency and sustainability
- plus a rapid deployment.
Traditional data center constructions
can take years to design, build and
kick off. Speed is definitely one of the
key advantages of a modular build, as
time savings of up to 50 percent can
be achieved. And the quicker a new
infrastructure is ready for operation, the
sooner the return on investment.
Expanding or building a traditional data
center in a short timeframe can be a
great challenge which requires significant
resources. After a thorough analysis, a
modular, containerized construction
proved to be the ideal option to successfully
achieve rapid availability and high
scalability; easily allowing for future phases
of expansion as well as a staged investment.
“The average lead time for a Tier III data
center like the Cerdanyola one is 24-30
months and we managed to build this
facility with the identical requirements in
just 9 months,” said Raúl. “This translates
directly to cost savings and also to a
higher profit.”
The Cornerstone of
T-Systems’ Data Center
Consolidation Program
“The construction of the Cerdanyola
del Vallès data center in Barcelona is the
cornerstone of T-Systems’ consolidation
EmersonNetworkPower.eu
Another key word is flexibility. The
purpose-engineered modules can
be tailored to the most stringent
requirements, and easily added to
an existing infrastructure as well as
dismantled and reassembled at a different
location to address changing business
needs. Moreover, capital and operational
expenditures can be sized to actual
business needs.
for Data Center Professionals
“The modular design gives us increased
flexibility and scalability for future
investment, while immediately offering
an array of benefits for our customers,”
said Núria Berché, Program Manager at
T-Systems Iberia. “Emerson Network
Power worked with us to deliver true
expertise and industry knowledge,
positioning us to provide a strong cloud
platform that serves both domestic and
regional customers in Europe.”
Not Just a Building-Block
Game
Specially designed and built in Emerson
Network Power’s dedicated Integrated
Modular Solutions facility in Croatia,
and later transferred to its location in
Barcelona, Spain, the T-Systems data
center consists of 38 integrated modules
hosting nearly 300 Knürr® racks, more
than 60 Liebert® thermal management
units and a number of Chloride® AC power
systems. The modular infrastructure
includes insulation, fire protection,
monitoring, and secure access control.
While building the containers in the
factory, civil works started preparing
the ground for the final installation on
site. The integrated modules were then
delivered according to a precise timeline,
assembled, and connected to all electrical,
mechanical, and plumbing systems. Once
finalized, the facility appeared a traditional
building both from the outside in,
comprising, for instance, meeting rooms,
galleries and walkways to access all areas
of the infrastructure.
“Emerson did a really good job, not only in
providing and delivering the data center
modules but also in the integration and
on site assembly,” explained Raúl Saura.
“It is not just putting the modules one
next to the other. You have to build the
cooling infrastructure, you have to set up
the power network, you have to do a lot of
things. It is not just a LEGO game where you
put the bricks in place and that’s it. That
complexity was performed by Emerson and
they did very well. Also, we are very pleased
about the excellent teamwork throughout
the assembly, installation, and final
commissioning of the data center, which
has been a great success.”
“Throughout the tender, Emerson proved
the most efficient and reliable supplier,”
added Sven Meyer. “The greatest
advantage was the complete portfolio
and unique point of reference: the high
vertical integration turned to be decisive
in delivering a fit-for-purpose solution in
optimal lead times.”
A Step into the Future
The Cerdanyola data center is currently
one of the largest modular data centers
for T-Systems in Spain, with a modular
IT load capacity of 1.1 MW, scalable up
to 5 MW in future phases. As a result,
T-Systems benefits from minimized
operating costs. The facility also received
the Data Centre Market award for most
innovative project in Spain, and has been
recognized by the Uptime Institute for
providing 99.98 percent availability. The
high efficiency design of the new facility
delivers a Power Usage Effectiveness
(PUE) of 1.3 and enables T-Systems to
reduce its overall electrical consumption
by 30 percent.
“If you consider that 30 to 40 percent of a
data center’s operational costs are those
for energy, you can perceive the impact
on our production costs,” added Raúl.
“We are now in the process of migrating
data from the existing infrastructures
to this new data center with the aim of
consolidating by 2018. It was absolutely
strategic to quickly and successfully
deploy this data center to fulfil T-Systems’
vision for the following years.”

5 Top Considerations
For Selecting A UPS
N
ew technologies and
increasing demands are
causing data center managers
to look to UPS solutions for efficiency
and scalability in addition to availability.
The considerations below will help you
select the right UPS solution for both
current and future needs and help
optimize the performance of your

1: UPS Topology
UPS internal topology (configuration)
determines the relationship between
the UPS output power quality and
incoming utility power and, ultimately,
the effectiveness of the UPS at
protecting against certain types of
power disturbances. Topology is
a primary determinant of system
reliability and functionality, two key
elements of availability. Historically,
there have been three basic types of
UPS topology:
Power Sag
Power Surge
Power Outage
Trinergy™ Cube
Passive Standby: While this
topology gets high marks for
simplicity, the limitations of the
design—such as the lack of power
conditioning, brief power interruption
during transfers, or generator
compatibility make it unsuitable for
three-phase applications.
Line-interactive: This topology
resembles passive standby, but inserts
a transformer or inductor in series
between the utility power source and
the load. Like the passive standby
topology, line-interactive can be
cost convenient but more effective,
because it supports the entire critical
load during power disturbances for
the duration of the battery.
10
Spring 2015
On-line Double-Conversion:
On-line double-conversion topologies
have emerged as the preferred
topology for the data center,
displacing standby and line-interactive
UPS systems in network access
rooms as availability requirements
rise. Properly configured, it is the
only topology that protects against
the full range of power disturbances
experienced by data center power
systems.
In the last few years a new topology
combining the three traditional ones
just described has been developed. In
this topology Maximum Power Control
EmersonNetworkPower.eu
(VFI or On-line double conversion),
High Efficiency & Power Conditioning
(VI or line interactive), and Maximum
Energy Saving (VFD or passive
standby) work together and the UPS
automatically switches between one
or the other thanks to an algorithm
sensing the grid power quality and
determining the topology to rely on
based on that.
2: Availability
To ensure your data center UPS
solution can protect uptime even
during multiple, simultaneous power
and environmental events without
forcing a switch to bypass, look for:
Continuous-duty static switch:
Ensures maximum fault clearing
capability in case of extreme
overload or downstream faults
No contactors in the bypass path:
Contactors are not designed for
high withstand requirements
Redundant fans: Provides
the ability to tolerate more than
a single fan failure before going
to bypass
for Data Center Professionals
High withstand rating (100kA
or higher): Allows the equipment
to stay online during more severe
short circuit or circuit overload
conditions
Virtually every component of the
data center physical infrastructure is
now available in a modular design,
including power systems.
Transformer-Free UPS: Offers
Remote diagnostic and preventive
monitoring services for increased
uptime, first time fix rate and
enhanced operational efficiency
by continuously monitoring and
tracking performance trends
These modular systems are typically
integrated packages of equipment
and controls that are built and
pre-tested in a factory environment.
The shorter deployment time,
combined with the “capacity-ondemand” approach offered by
modularity, allows organizations to
quickly meet fluctuating demands
while managing capital expenditure
costs and maintaining higher
operating efficiencies. This is taken
even further by those Power Systems

that nowadays is possible up to 3 MW

3: Efficiency
UPS power consumption has
improved significantly since the
days of 79 percent efficiencies, even
more if you think of the topology
just described combining the three
traditional ones which achieve very
high operational efficiency levels
(98.5%) and double conversion online
efficiency up to 97%.
4: Scalability and
Flexibility
5: Design
Power system flexibility can be
provided by a new generation of
power systems that are designed for
simplified configuration changes and
greater scalability, enabling systems to
be right-sized during the design phase.
There are a number of new
technologies that expand upon the
on-line double-conversion topology

Don’t Let Desktop Systems
Threaten Your Network Security
W
e like to think employees
are committed to
maintaining IT security
and abiding by privacy and security
regulations. But it takes just one bad
apple or someone who inadvertently
downloads sensitive material from
their desktop onto a thumb drive
for organizations to end up with
a significant loss of intellectual
property, severe reputational damage
and substantial fines and penalties.
The importance of risk management
at the network level has long been
understood, but risk management at
the desktop level has sometimes been
an afterthought. With the growing
potential for harm, it’s time for risk
management to extend right down to
each individual’s workstation.
A new briefing document from
Emerson Network Power discusses
technologies specifically designed
to manage desktop security.
These technologies can help you
substantially reduce risk by:
Tightly controlling how users
access computers
Control What the User
Can Do At the Desktop
Deliver Security with
User Transparency
The key to reducing risk at the
desktop is to carefully manage user
access to any computer. Using a
secure desktop KVM switch is an
excellent way to achieve this level of
control.
While desktop security is growing
in importance, it cannot come at
the expense of making it harder
for people to get work done.
Sophisticated KVM switches
provide multiple ports in order to
support a virtually unlimited array of
computers, from PCs running basic
applications to high-end graphic
applications, for example. With a
KVM switch, users need just a single
keyboard, monitor and mouse to
access multiple computers.
This hardware device can control one
of the easiest and most common
ways for sensitive data to be stolen or
inadvertently leaked—through USB
devices. With a KVM switch, the types
of USB devices that can be used with a
target computer can be restricted.
For example, the switch allows only
the desktop’s keyboard, screen
and mouse to function on a target
computer, prohibiting any other USB
device from accessing the target,
such as a flash or hard disk drive,
camera or printer. This effectively
prevents unauthorized downloads via
the desktop. In addition, the switch
can constantly monitor all the devices
attached to it, ignoring any access
attempts using an unauthorized USB
device.
Ensuring IT and system
administrators monitor and
manage equipment as efficiently,
effectively and securely as possible.
12
Spring 2015
EmersonNetworkPower.eu
An added benefit is that organizations
can reduce costs as they no longer
need to buy multiple peripherals
for each user. In addition, where
users need access to a mix of secure
and unsecured computer systems,
the KVM switch provides a discrete
processing path to each computer.
for Data Center Professionals
Extend Desktop
Security with
Remote, Centralized
Management
For some organizations, it may be
desirable to physically separate
computer systems from users and to
centralize the management of desktop
access and control. There are several
good reasons to consider using remote
centralized management to control
desktop access:
Reduce risk by placing computers
in a secure location and by allowing
multiple administrators in different
locations to collaborate.
Reduce costs as users still need
only one set of peripherals to
access multiple systems, and they
can easily share computers, reducing
the amount of systems that must
be bought.
Centralized remote management
requires a high performance digital
KVM switch that can deliver an
“at-the-desktop” experience
whenever users attach to a remotely
located computer. This is particularly
important where a high-fidelity
experience is crucial, such as in control
rooms for manufacturing, utilities,
broadcasting and emergency response,
or training/simulation, medical
diagnosis and financial trading desks.
When considering managing desktop
access remotely, look for digital KVM
solutions that are platform-agnostic,
support a comprehensive range of
peripherals and ensure a pixel-perfect
user experience.

Thermal Management
Best Practices and Upgrades
Learn how to save
30% on efficiency in
just 15 minutes
Recently, some of our Emerson
Network Power Thermal Management
engineers toured 15 data centers
that serve everything from midsized
businesses to Fortune 50 technology
companies. In each case they were
able to identify significant energy
saving opportunities – up to 30%
savings - by asking just a few general
questions. Often, these savings could
be realized with the implementation
of a thermal management best
practice. Below are the most common
opportunities they came across.
Increase the
temperatures in your
data center: The old
standard was 24°C for return air
(the mixture of air returning from
computers to the cooling unit) and
relative humidity at 50%. Today, you
can push return air temperatures
as high as 37°C, using hot or cold
aisle containment, while keeping
the servers at the right temperature.
It is recommended that this be
done in small increments to avoid
unexpected humidity trouble and
to ensure all the IT equipment is
functioning properly. This can be
done over a few days with little risk
to applications and IT equipment.
Enlist your facilities manager or
vendor partners to assess the safest
way to do this. Remember for every
1°C increase in temperature you will
save 1.5-2.0 % of your energy costs.

Raise chilled water
temperatures: For data
centers using chilled
water, 7°C used to be the standard
temperature for water delivered by
the freecooling chiller. Today, it is
possible to operate freecooling chillers
up to 14°C and even 20°C for new
units, reducing energy consumption
by 20%. Every degree matters—
each one degree increase in water
temperature reduces freecooling
chiller energy consumption by four
percent. It is important that you work
with your facilities manager as raising
chilled water set points could reduce
cooling capacity in your data center
cooling units.
its speed – through a variable capacity
compressor – the more energy you will
save.
Match your cooling
requirements to your
IT Load: Your thermal
management equipment should have
variable capacity components (fans
and compressors, if applicable) to
adjust cooling capacity up and down
with your IT load. While constant speed
fans are common, they are unable
to adjust to a data center’s actual
performance. A 3.5 kW fan motor
uses 4.0kWh of electricity at 100%
speed, but only 2.8kWh at 90%, and
1.3kWh at 70%. Savings are significant
(and exponential) when fan speed
can be matched to the data center’s
actual requirements. In addition, the
compressor is the highest consumer of
power in a direct expansion (DX) based
system. So the more you can turn it
off – through freecooling – or reduce
Upgrade Your Controls:
New controls provide the
ability to safely implement
and coordinate each of the previously
mentioned strategies. When new
controls and variable capacity
component strategies are added to
the operational tweaks described
previously, power consumption from
cooling in a typical enterprise data
center with 500kW of IT load, can
potentially drop more than 50%, from
380kW to 184kW or €171,690 in
annual energy savings assuming €0.1
per kW hour. That potentially can lower
the mechanical PUE from 1.76 to 1.37.

Use Hot or Cold
Aisle Containment:
Containment prevents
the mixing of hot and cold air, which
increases the temperature of the
return air (the hot air being expelled
from racks and circulated back to the
heat removal equipment). Higher
return air temperatures allow heat
removal units to operate more
efficiently. A 12°C increase in return
air temperature can create a 38%
increase in cooling unit capacity and
an increase in efficiency.

Are Your Rack PDUs Keeping
You From Optimizing Power
Management?
Data center investments are sizable, and
each component of the power chain—
from the building entrance to the rack
power distribution—is crucial to enabling
equipment availability, efficiency and
capacity. To ensure you are optimizing
your data center power at the rack PDU
level, consider these features:
Designed for High Availability
Is your rack PDU designed to operate in
the high temperatures common at the
back of the rack? Is it designed to optimize
basic power availability? Is it easily upgraded to minimize
downtime? Look for:
High temperature rating
Hot swappable controller card
Bistable / normally closed relays
