IT virtualization, the engine behind cloud computing, can have significant consequences on the data center physical infrastructure (DCPI). Higher power densities that often result can challenge the cooling capabilities of an existing system. Reduced overall energy consumption that typically results from physical server consolidation may actually worsen the data center’s power usage effectiveness (PUE). Dynamic loads that vary in time and location may heighten the risk of downtime if rack-level power and cooling health are not understood and considered. Finally, the fault-tolerant nature of a highly virtualized environment could raise questions about the level of redundancy required in the physical infrastructure. These particular effects of virtualization are discussed and possible solutions or methods for dealing with them are offered.

Microgrid & renewable integration at burbank water & powerSchneider Electric
This presentation reviews Schneider Electric's collaboration avec Burbank Water and Power, a cutting-edge utility company in Burbank, California, to achieve challenging renewable energy requirements and provide reliable, safe, and affordable power to its customers using advanced technology solutions.
To prepare for increased renewable energy requirements, Burbank Water and Power sought a system to manage load, distributed energy resources, distributed storage systems, generation, and variable renewables in order to balance supply and demand and avoid undesirable voltage, power flow, and power quality problems. Burbank’s Integrated Automated Dispatch System (ADS) includes Schneider Electric’s advanced Power Control System (PCS) - for automatic generator control, load forecasting, and renewable forecasting - integrated with Schneider Electric’s OASyS SCADA and WeatherSentry system. The Integrated ADS will allow Burbank to co-optimize scheduling and dispatch of conventional supply resources, distributed generation, and demand-side resources, enable better control of inadvertent interchanges, and reduce reliance on external generation. Through the Integrated ADS, Burbank’s system operators will be able to manage the available system resources to optimize system reliability while achieving the most economic and sustainable energy supply portfolio.
High Efficiency Indirect Air Economizer Based Cooling for Data CentersSchneider Electric
Of the various economizer (free cooling) modes for data centers, using fresh air is often viewed as the most energy efficient approach. However, this paper shows how indirect air economizer-based cooling produces similar or better energy savings while eliminating risks posed when outside fresh air is allowed directly into the IT space.
The combination of Cisco's UCS Manager and Schneider Electric's DCIM solution provides Cisco UCS customers with an opportunity to bridge the gap between IT and Facilities, offer transparency across the two silos, and positively impact the rest of the organization – both in terms of efficiency, uptime and capex/opex costs. This is achieved by optimising the existing physical infrastructure capacities, thus reducing overprovisioning and improving the balance between supply and demand, resulting in continual availability and optimal energy efficiency.
Human error is directly attributable to 70% of data center outages according to the Uptime Institute. This session highlights the critical importance of having an effective operations and maintenance (O&M) program and provides a comprehensive, high-level overview of the necessary elements of a program to operate a critical facility efficiently and reliably throughout its life cycle.
Implementing Hot and Cold Air Containment in Existing Data CentersSchneider Electric
Containment solutions can eliminate hot spots and provide energy savings over traditional uncontained data center designs. The best containment solution for an existing facility will depend on the constraints of the facility. While ducted hot aisle containment is preferred for highest efficiency, cold aisle containment tends to be easier and more cost effective for facilities with existing raised floor air distribution. This presentation investigates the constraints, reviews all available containment methods, and provides recommendations for determining the best containment approach.

Field Data Gathering Services — A Cloud-Based ApproachSchneider Electric
Utilities today wish to facilitate the capture of asset information in the field in a way that is not only scalable but cost effective. They need a system that is simple to use, inexpensive to implement, flexible enough to meet ever-changing needs, yet also powerful enough to cover a majority of their needs with immediacy. This paper describes Schneider Electric's powerful cloud-based solution to optimize the inspection and gathering of field information.
A key part of implementing Volt-VAR control and optimization is to identify the benefits that can be attributed to VVO. The major challenge is to separate the impacts of VVO (i.e. the VVO benefits) from the impacts of factors not related to VVO, such as changing weather conditions, random customer behavior and routine operational changes (planned switching). Utilities on the panel have performed VVO measurement and verification using different methods. Each presenter will describe how the method works, data requirements, strengths and weaknesses of the approach and results. The session also will summarize work by the IEEE Volt-VAR task force to develop IEEE Guideline P1885 M&V of VVO projects for electric distribution utilities.

Row-based data center cooling is normally regarded as
a “cold air supply” architecture that uses row-based
coolers. However, row-based cooling is actually a “hot
air capture” architecture that neutralizes hot air from IT
equipment before it has a chance to mix with the
surrounding air in the room. This paper discusses
common misconceptions aboutrow-based cooling,
explains how row-based cooling removes hot air, and
describes key design attributes that maximize the
effectiveness of this approach.

Effective power management is quickly becoming a major concern for data centers of all sizes. Specialized power management software is now available to help meet these needs. We tested two of these power management tools, Dell OpenManage Power Center and JouleX Energy Manager for Data Centers.
Both Dell OpenManage Power Center 2.0 and JouleX Energy Manager address some of the most common critical power tasks for your data center servers. JouleX Energy Manager is a product that includes additional features, but you must pay upfront acquisition costs and incur recurring software maintenance costs for potentially less-common features that just a subset of IT departments may implement. In contrast, Dell OpenManage Power Center, when used in conjunction with iDRAC Enterprise, comes at a very compelling price point – $0.00. This translates to a great value and an immediate return on investment.

More Electric:
Our world is becoming More Electric. Almost everything we interact with today is either already electric or becoming electric. Think about it. From the time you start your day in the morning to the time you finish your day – your home, your car, your work, your devices, your entertainment – almost everything is electric. Imagine the energy needed to power this. Electricity consumption will increase by 80% in next 25 years
More Connected: Our lives are also becoming more connected. The Internet has already transformed the way we live, work and play. Now the Connected Things is going to take this to a brand new level. 50 billion things connected in the next 5 years.
More Distributed: With such a widespread electrification and connectivity, energy models need rethinking as well. Which is why the generation of power needs to be closer to users. Distributed Energy is rapidly evolving globally. This is positive energy – renewable. In 2014 , Renewables overtook fossil fuels in investment value, with $295bn invested in renewables compared to $289bn invested in fossil fuels. And it is getting cheaper to do this.
More Efficient: When our world is more electric, more connected and more distributed, new opportunities emerge and allows us to tap into even more efficiency – in industrial processes, in the energy value chain, in buildings, in transportation, in the global supply chain and even in the comfort and peace-of-mind of our homes.
With more than $18 billion in M&A activity in the first half of last year alone, the colocation industry is riding the bubble of rapid growth. Colocation data center providers are being evaluated by a wide range of investors, with varying experience and perspectives. Understanding the evaluation criteria is a critical competency for attracting the right type of investor and financial commitment for your colocation business and this is why we have invited today’s speaker to present.

> Executive summary
IT virtualization, the engine behind cloud computing,
can have significant consequences on the data center
physical infrastructure (DCPI). Higher power densities
that often result can challenge the cooling capabilities
of an existing system. Reduced overall energy con-sumption
that typically results from physical server
consolidation may actually worsen the data center’s
power usage effectiveness (PUE). Dynamic loads that
vary in time and location may heighten the risk of
downtime if rack-level power and cooling health are not
understood and considered. Finally, the fault-tolerant
nature of a highly virtualized environment could raise
questions about the level of redundancy required in the
physical infrastructure. These particular effects of
virtualization are discussed and possible solutions or
methods for dealing with them are offered.

2. Virtualization and Cloud Computing: Optimized Power, Cooling and Management
Maximizes Benefits
Without question, IT virtualization - the abstraction of physical network, server, and storage
resources - has greatly increased the ability to utilize and scale compute power. Indeed,
virtualization has become the very technology engine behind cloud computing itself. While
the benefits of this technology and service delivery model are well known, understood, and
increasingly being taken advantage of, their effects on the data center physical infrastructure
(DCPI) are less understood. The purpose of this paper is to describe these effects while
offering possible solutions or methods for dealing with them.
These effects are largely not new and successful strategies for dealing with them exist today.
There are four effects or attributes of IT virtualization that will be covered in this paper.
1. The rise of high density – Higher power density is likely to result from virtualization,
at least in some racks. Areas of high density can pose cooling challenges that, if left
unaddressed, could threaten the reliability of the overall data center.
2. Reduced IT load can affect PUE – After virtualization, the data center’s power usage
effectiveness (PUE) is likely to worsen. This is despite the fact that the initial physical
server consolidation results in lower overall energy use. If the power and cooling
infrastructure is not right-sized to the new lower overall load, physical infrastructure
efficiency measured as PUE will degrade.
3. Dynamic IT loads – Virtualized IT loads, particularly in a highly virtualized, cloud data
center, can vary in both time AND location. In order to ensure availability in such a
system, it’s critical that rack-level power and cooling health be considered before
changes are made.
4. Lower redundancy requirements are possible – A highly virtualized data center
designed and operated with a high level of IT fault-tolerance may reduce the necessity
for redundancy in the physical infrastructure. This effect could have a significantly
positive impact on data center planning and capital costs.
This paper approaches these effects in the context of a highly virtualized environment typical
of a cloud-based data center with dynamic demand requirements. The list of white papers at
the end provides additional general and detailed information about these topics in the overall
data center context, virtualized or not.
While virtualization may reduce overall power consumption in the room, virtualized servers
tend to be installed and grouped in ways that create localized high-density areas that can
lead to “hot spots”. This cooling challenge may come as a surprise given the dramatic
decrease in power consumption that is possible due to high, realistically achievable physical
server consolidation ratios of 10:1, 20:1 or even much higher. As a physical host is loaded
up with more and more virtual machines, its CPU utilization will increase. Although far from
being a linear relationship, the power draw of that physical host increases as the utilization
increases. A typical non-virtualized server’s CPU utilization is around 5%-10%. A virtualized
server, however, could be 50% or higher. The difference in power draw between 5% and 50%
CPU utilization would be about 20% depending on the specific machine in question. Addi-tionally,
virtualized machines will often require increased processor and memory resources
which can further raise power consumption above what a non-virtualized machine would
draw. Grouping or clustering these bulked up, virtualized servers can result in significantly
higher power densities that could then cause cooling problems. Not only are densities
increasing, but virtualization also allows workloads to be dynamically moved, started, and
stopped – the result can be physical loads that change both over time AND in their physical
location. This effect of dynamic loads is discussed later in this paper.

Methods for cooling high density racks to prevent “hot spots”
Higher rack power densities should encourage data center operators to examine their existing
cooling infrastructure to see if it can still sufficiently cool the load. Several approaches for
cooling high density racks exist. Two of the principal ones are briefly explained here.
Perhaps the most common method is to simply “spread out” the high density equipment
throughout the data center floor rather than grouping them together. By spreading out the
loads in this way, no single rack will exceed the design power density and consequently
cooling performance is more predictable. The principle benefit of this strategy is that no new
power or cooling infrastructure is required. However, this approach has several serious
disadvantages including increased floor space consumption, higher cabling costs, possible
reduced electrical efficiency related to uncontained air paths and the perception that half-filled
racks are wasteful. That being said, this simple approach may be a viable option
particularly…
• When the resulting average data center power density (kW/rack or watts/sq foot of white
space) is about the same or less than it was before virtualization. (Assumes there was
sufficient cooling capacity before.)
• When managers have complete control over where physical servers are placed.
• When “U” space is available in existing racks to allow the spreading to happen.
A more efficient approach may be to isolate higher density equipment in a separate location
from lower density equipment. This high density pod would involve consolidating all high
density systems down to a single rack or row(s) of racks. Dedicated cooling air distribution
(e.g., rack and row-based air conditioners), and/or air containment (e.g., hot or cold aisle
containment), could then be brought to these isolated high density pods to ensure they
received the predictable cooling needed at any given time. The advantages include better
space utilization, high efficiency, and that it enables maximum density per rack. Additionally,
for organizations that require high density equipment to remain co-located together, this
approach is obviously preferred. Figure 1 illustrates the idea of a high density pod.

• Thermally neutral to the rest of the room
(may actually assist the room if the pod
has excess capacity)
• Hot/cool air circulation is localized within
the zone by short air paths and/or physi-cal
containment
Important basic characteristics of a high density pod include:
• Short air paths (when air streams are uncontained) to minimize possibility of mixing
supply and return air, as well as to minimize energy used by variable speed fans.
• Variable Frequency Drive (VFD) fans to account for dynamic loads that vary in both time
and location.

• Rack and/or row orientation that facilitates the separation of cold supply air from hot
return air.
Isolating high density equipment into a separate pod with dedicated cooling makes manage-ment
simpler, cooling performance more predictable and energy is used more efficiently. At a
minimum, the high density pod is thermally neutral to the rest of the room. But, particularly
when air streams are well contained, the pod may likely add cooling capacity to the rest of the
data center.
For more detailed information regarding the use of separate, isolated high density pods, see
White Paper 134, Deploying High Density Pods in a Low Density Data Center. For more
general information about all the various methods for cooling high density equipment, see
White Paper 46, Cooling Strategies for High Density Racks and Blade Servers.
A widely touted benefit of virtualization has been reduced energy costs as a result of physical
server consolidation. And, indeed, these savings are often not trivial. Consider a 1MW data
center with 1000 physical servers that draw 250W each at a cost of $0.11 per kilowatt/hr.
The energy cost per year to operate just the servers would be about $240,000 (250W/1000 x
0.11 x 24hr x 365 days x 1000 servers). Virtualize these servers at a conservative consolida-tion
ratio of 10:1 with each remaining physical server operating at a CPU utilization of 60%
(instead of the typical 5-10%) and you now get a total energy cost of about $60,000
(600W/1000 x 0.11 x 24hr x 365 days x 100 servers)1. That represents an energy savings of
76% for the servers. So it is no wonder that virtualization is widely viewed and promoted as a
“green” technology for the data center. Compute capacity remains the same or is even
increased while energy use drops sharply.
It may come as a surprise, then, that in such a “green” scenario the most commonly used
metric for data center efficiency, PUE, could worsen after this server consolidation took place.
Perhaps some might see this as a short-coming of the metric. That is, an efficiency metric
must be deficient if it is not intended to reflect the obvious environmental benefit of signifi-cantly
lower energy use. But the reader must remember that PUE is a metric designed to
only measure efficiency of the data center physical infrastructure (i.e. power and cooling),
and not the IT compute power efficiency. PUE should never be used or thought of as a direct
indicator for how “green” a particular data center is. The purpose is to show how efficient the
power and cooling systems are for a given IT load. Figure 2 illustrates the effect of virtual-ization

1 The same physical host at 60% CPU utilization would bring the power consumption to about 300W. The
additional 300W to bring the total to 600W is assumed due to the increased processor and memory
resources required to properly handle the virtualized loads. Note that storage energy from NAS or SAN
may increase but overall IT energy savings is still significant.

Virtualization’s track on the infrastructure efficiency curve
If the power and cooling infrastructure is left alone as it was before virtualization was
implemented, then PUE will worsen after the physical consolidation of servers and storage
has taken place. Inherent in unused power and cooling capacity is what is known as “fixed
losses”. This is basically power that is consumed by the power and cooling systems regard-less
of what the IT load is. The more power and cooling capacity that exists, the more fixed
losses will exist. As the IT load shrinks (e.g., from consolidation) these fixed losses become
a higher proportion of the total data center energy use. This means PUE will worsen. This
also means that PUE is always better at higher IT loads and worse at lower loads. Figure 3
shows a typical PUE curve illustrating the relationship between efficiency and the IT load.

To improve post-virtualization PUE, the data center’s infrastructure efficiency curve must be
improved (lowered) by optimizing power and cooling systems to reduce the waste of oversiz-ing
and better align capacity with the new, lower load (Figure 5). In addition to improving
efficiency, optimized power and cooling will directly impact the electric bill by reducing the
power consumed by unused power and cooling capacity. The case study used to quantify
these PUEs is located the Appendix of this paper.

To improve PUE, reduce fixed losses
To realize the full energy-saving benefits of virtualization, an optimized power and cooling
infrastructure should incorporate design elements such as the following to minimize fixed
losses and maximize the electrical efficiency of the virtualization project overall:
• Power and cooling capacity scaled down to match the load (e.g. turn off some cooling
units or remove UPS modules from scalable UPS)
• VFD fans and pumps that slow down when demand goes down
• Equipment with better device efficiency, to consume less power in doing the job
• Cooling architecture with contained or shorter air paths (e.g. contain the hot or cold
aisle or move from perimeter room-based to row-based)
• Capacity management system, to balance capacity with demand and identify stranded
capacity
• Blanking panels to reduce in-rack air mixing of exhaust air with cold supply air
Although likely to have the biggest impact, scaling down power and cooling capacity may be
the most difficult to implement for an existing data center. Reducing the capacity of these
systems simply may not be feasible in certain situations. The system may not be divisible if
the design is not modular. The infrastructure systems in question could be new and recently
paid for, making replacement or significant modification impractical. The dependence of

other systems or operations outside of the white space on a given infrastructure element (e.g.
packaged chiller plant) may preclude the time required and ability to reduce its capacity. So
the costs of rightsizing the power and cooling infrastructure may very well outweigh the
benefits of closely aligning supply with demand. For an existing data center, perhaps more
feasible options might include doing such things as:
• Installing blanking panels to reduce air mixing
• Orienting racks into separate hot and cold aisles
• Install air containment technologies
• Adjusting fan speeds or turning off cooling units
• Removing unneeded UPS power modules for scalable UPSs
For a new data center that is currently in design, however, rightsizing the entire power and
cooling plant to the load makes more sense. Doing so at this phase will mean lower initial
upfront capital costs and much better energy efficiency once the data center is operational.
As the example in the appendix illustrates, an existing data center can still see significant
energy savings and PUE improvement even if they only focus on making their existing power
and cooling systems operate more efficiently by implementing the options listed above.
Standardization and modularity make rightsizing easier
However, in spite of the feasibility issues just described for existing data centers, oversized
capacity is inefficient and wasteful. And as the sidebar to the left shows, there are additional
negative effects from having an under-loaded power and cooling system. Fortunately,
today’s power and cooling solutions make it easier even for an existing data center to keep
capacity more closely aligned with actual demand. This is, in large part, because they are
scalable for capacity. And this scalability is derived from both standardization and modulari-ty.
Adding capacity to traditional, non-modular systems required onsite engineering to custom
design and assemble various components together from multiple manufacturers. Later
modifying or reducing capacity for those traditional systems would be costly, highly disruptive
and time-consuming. By designing power and cooling systems so that they are standardized,
factory assembled/tested and modular in nature, it becomes much easier and less risky to
add or remove capacity. For example, UPS power capacity can be quickly and safely
reduced by simply removing power modules from the chassis. This can be done without
interrupting power to the load and specialized service personnel are not required. Removing
these power modules reduces fixed losses, thereby improving PUE. These modules can be
set aside and later reused as the load increases over time. Cooling systems today are often
scalable as well. Variable speed fans, for example, can increase or decrease speed as
needed based on the heat load. As the overall IT load decreases after initial virtualization,
fans can run at a much lower speed thereby reducing proportional losses (power consumed
by the system that is proportional to its load) which also helps improve PUE. Scalable
physical infrastructure closely aligned with real-time management (to be discussed later) can
help provide the right amount of power and cooling where it’s needed, when it’s needed. This
makes rightsizing a more realistic option once a data center has been virtualized.
So how much additional energy savings can be had by rightsizing the infrastructure?

> Effects of extreme
under-loading
Unless power and cooling are
down-sized to bring loading
back within normal operating
limits, these effects could
result in expenses that negate
some of the energy savings or,
in some cases, pose a risk to
availability.
Cooling (too-low thermal load)
•Safety shutdown because of high
head pressure on compressors
•Short-cycling of compressors
from frequent shutdown, which
shortens compressor life
•Possible voiding of warranty from
consistent operation below low-load
limit
•Cost of hot-gas bypass on
compressors to simulate ”normal”
load to prevent short-cycling
Generator (too-low electrical
load or too many generators)
•Unburned fuel in the system (“wet
stacking”), which may result in
pollution fines or risk of fire
•Cost of unneeded jacket water
heaters to keep engines warm
•Cost of storage, testing, and
maintenance of excess fuel

> Effect of reduced power consumption on energy and service
contracts
An abrupt reduction in power consumption may have unintended consequences with regard to
utility and service contracts. Such contracts will need to be reviewed and renegotiated where
necessary, in order not to forfeit data center savings to the utility provider, building owner, or
service provider.
• Utility contract – Agreements with utility providers may include a clause that penalizes the customer if
overall electrical consumption drops below a preset monthly consumption amount.
• Energy clause in real estate agreement – Some real estate agreements include the cost of electricity as a
flat rate, typically billed on a cost-per-square-foot basis. This agreement may need to be renegotiated,
otherwise the savings from virtualization will accrue to the building owner.
• Equipment service contracts – Service contracts should be reviewed to remove unused power and cooling
equipment, to avoid paying for service on equipment that has been taken out of service through down-sizing.

The sudden - and increasingly automated - creation and movement of virtual machines
requires careful management and policies that contemplate physical infrastructure status and
capacity down to an individual rack level. Failure to do so could undermine the software
fault-tolerance that virtualization imbues to cloud computing. Fortunately, tools exist today to
greatly simplify and assist in doing this.
The electrical load on the physical hosts can vary in both time and place as virtual loads are
created or moved from one location to another. As the processor computes, changes power
state or as hard drives spin up and down, the electrical load on any machine – virtualized or
not - will vary. This variation can be amplified when power management policies are
implemented which actively power machines down and up throughout the day as compute
needs change over time. The policy of power capping, however, can reduce this variation.
This is where machines are limited in how much power they can draw before processor
speed is automatically reduced. At any rate, since data center physical infrastructure is most
often sized based on a high percentage of the nameplate ratings of the IT gear, this type of

variation in power is unlikely to cause capacity issues related to the physical infrastructure
particularly when the percentage of virtualized servers is low.
A highly virtualized environment such as that characterized by a large cloud-based data
center, however, could have larger load swings compared to a non-virtualized one. And,
unless they are incredibly well-planned and managed, these could be large enough to
potentially cause capacity issues or, at least, possibly violate policies related to capacity
headroom.
Increasingly, managers are automating the creation and movement of VMs. It is this unique
ability that helps make a virtualized data center more fault-tolerant. If a software fault occurs
within a given VM or a physical host server crashes, other machines can quickly recover the
workload with a minimal amount of latency for the user. Automated VM creation and
movement is also what enables much of the compute power scalability in cloud computing.
Ironically, however, this rapid and sudden movement of VMs can also expose IT
workloads to power and cooling problems that may exist which then put the loads at
risk.
DCIM and VM manager integration to automate safer VM placement
Data center infrastructure management (DCIM) software can monitor and report on the health
and capacity status of the power and cooling systems. This software can also be used to
keep track of all the various relationships between the IT gear and the physical infrastructure.
Knowing such things as which servers, physical and virtual, are installed in a given rack along
with knowing which power path and cooling system it is associated with should be required
knowledge for good VM management. This knowledge is important because without it, it is
virtually impossible to be sure virtual machines are being created in or moved to a host with
adequate and healthy power and cooling resources.
Relying on manual human intervention to digest and act on all the information provided by
DCIM software can quickly become an inadequate way to manage capacity, considering the
many demands already placed on data center managers. The need for manual intervention
introduces the risk of human error, a leading cause of downtime. Human error, in this case, is
likely to take the form of IT load changes without accounting for the status and availability of
power and cooling at a given location. Automating both the monitoring of DCIM information
(available rack space, power, and cooling capacity and health) and the implementation of
suggested actions greatly reduces the risk.
Data Center Infrastructure Management (DCIM) software is available that can provide this
real-time, automated management. An example of this is shown in Figure 7. The two-way
communication between the VM manager and DCIM software and the automation of action
that result from this integration is what ensures physical servers and storage arrays receive
the right power and cooling where and when needed.

10. Virtualization and Cloud Computing: Optimized Power, Cooling and Management
Maximizes Benefits
A VM is created or moved to a different physical server typically because there are not
enough processor, memory, or storage resources available at a given moment and location.
But an effective management system can directly cause VMs to move based also on real-time,
physical infrastructure capacity and health at the rack level. When DCIM software is
integrated with the VM manager, VMs can be safely and automatically moved to areas known
to have sufficient power and cooling capacity to handle the additional load. Conversely, VMs
can be moved away from racks that develop power or cooling problems. For example, if
there’s a power outage at a rack, a cooling fan stops working or there is a sudden loss of
power redundancy, the VM manager can be notified of the event and the “at risk” VMs can be
moved to a safe and “healthy” rack elsewhere in the data center. All of this happens auto-matically
in real time without staff intervention. DCIM software integration with a VM manager
is a key capability for ensuring that virtual loads and their physical hosts are protected. In
turn, service levels will be more easily maintained and staff will be freed from having to spend
as much time physically monitoring the power and cooling infrastructure.
This integration becomes even more critical as power and cooling capacities are reduced or
rightsized to fit a newly virtualized or consolidated data center. The less “head room” or
excess capacity that exists, the less margin for error there is for placing virtual machines.
Maintaining a highly efficient, leanly provisioned data center in an environment
characterized by frequent and sudden load shifting requires a management system
that works automatically in real time with the VM manager.
Also, it should not be forgotten that IT policies related to VM management need to be
constructed so that power and cooling systems are considered. This must occur in order for
the DCIM software integration with the VM manager to work as described above. Policies
should set thresholds and limits for what is acceptable for a given application or VM in terms
of power and cooling capacity, health, and redundancy.

11. Virtualization and Cloud Computing: Optimized Power, Cooling and Management
Maximizes Benefits
The reduced need for power and cooling capacity is a commonly known benefit of IT virtual-ization
as described in the prior section, Reduced IT load can worsen PUE. A lesser known
benefit, however, is that IT virtualization can lead to a reduced need for redundancy in the
physical infrastructure. Relying more on the fault-tolerance of well-managed virtual machines
(and the applications that run on them), and less on higher levels of infrastructure redundan-cy
could simplify design, lower capital costs, and save space for other needed systems or for
future IT growth.
A highly virtualized environment is similar to a RAID array in that it is fault tolerant and highly
recoverable. Workloads, entire virtual machines, and virtualized storage resources can be
automatically and instantly relocated to safe areas of the network when problems arise. This
shifting of resources to maintain uninterrupted service occurs at a level that is essentially
transparent to the end user. However, depending on the quality of IT implementation and the
level of integration of the virtual machine (VM) manager software, the end user may experi-ence
momentary latency issues while this migration takes place. But, generally speaking,
service levels can be maintained in a highly virtualized environment even when some servers
or racks become unavailable.
Given this fault tolerance, there may be a reduced need for a highly redundant (i.e., 2N or
2N+1) power and cooling system in a highly virtualized data center. If, for example, the
failure of a particular UPS does not result in business disruption, it may not be necessary to
have a backup, redundant UPS system for the one that just failed. Those planning to build a
new data center with “2N” redundant power and cooling systems, perhaps could consider
building an N+1 data center instead. This would obviously significantly reduce capital costs
and simplify the design of the infrastructure. It’s the fault tolerance of a highly virtualized
network that allows organizations to consider this reduced infrastructure redundancy as a real
option now. Before making these types of decisions, of course, IT and Facilities manage-ment
should always fully consider the possible impacts to business continuity if the physical
infrastructure system or component being considered fails or becomes unavailable. This
means IT management systems and policies should be reviewed and monitored to ensure
they are capable of providing the level of service and fault tolerance that permits having less
redundancy in the physical infrastructure. This matching of physical infrastructure redundan-cy
to the fault-tolerant nature of a virtualized IT environment is another form of the rightsizing
described earlier. Rightsizing in this way can further reduce energy consumption, capital
costs, and fixed losses all while improving the data center PUE.

12. Virtualization and Cloud Computing: Optimized Power, Cooling and Management
Maximizes Benefits
Virtualizing a data center’s IT resources can have certain consequences related to the
physical infrastructure. If these impacts and consequences are ignored, the broad benefits of
virtualization and cloud computing can be limited or compromised, and in some cases,
severely so. Areas of high density can develop after server consolidation takes place which
may result in hot spots that can then lead to hardware failure. Various methods exist to
ensure the cooling system has the means and capacity to reliably cool high density equip-ment.
PUE can significantly worsen after consolidation occurs. By optimizing the power and
cooling systems to better match this now reduced IT load, PUE can be significantly improved.
This optimization is made much easier if scalable and modular systems are used. Dynamic
IT loads which can change automatically in both time and location may unintentionally be put
at risk if power and cooling status is not first considered at an individual rack level. Careful
planning and on-going management is required to ensure VMs are only placed where healthy
power and cooling exists. By constructing sound VM policies and by integrating DCIM
software with the VM manager, this on-going management can be automated. Finally, the
high level of fault tolerance that is possible with today’s VM manager software makes it
possible to employ a less redundant power and cooling infrastructure. Such a strategy can
save time, space, energy and significantly lower capital costs. Implementing the solutions
described in this paper will keep a highly virtualized data center running with greater reliabil-ity,
efficiency, and with expanded flexibility to meet highly dynamic compute power demand.

improvements
This case study was performed using the APC TradeOff Tool™ Virtualization Energy Cost
Calculator. This hypothetical 1 MW data center is assumed to be 70% loaded with no
redundancy in power and cooling with an electric bill of over $1,400,000 (Figure 8).
The data center is virtualized with a 10-to-1 decrease in server power. Because of the load
reduction from virtualizing, the power and cooling infrastructure is now underloaded, and
operates at reduced infrastructure efficiency (PUE 2.25) due to fixed losses, as described in
this paper. At this stage, the total electrical bill would be reduced by only 17%. However, the
PUE would further decrease to 1.63 and the electricity savings would reach 40% if the UPS,
PDUs, and cooling units were also rightsized and air containment (e.g. blanking panels
installed) methods employed. It should be noted that compared to the load after virtualization
prior to optimizing the infrastructure, the overall data center load on the physical infrastruc-ture
would increase due to the rightsized data center capacity. And this would mean that the
rated capacity of the overall data center would decrease given that the physical infrastructure
had been rightsized to the lower IT load.
