1. Cooling Product Positioning
Baseline Positioning
Regional Comparisons may vary based on climate
The purpose of this presentation is to provide a high level position of the core cooling products including our UniFlair and EcoBreeze Room Cooling products and InRow Close Coupled Cooling Products.
This overall positioning is based around the differences in first cost, efficiency and 3 year total cost to provide a starting point in deciding where to begin the conversation around cooling with a customer. We realize there are other more qualitative factors that influence the buying decision of the customer. These factors are also discussed in terms of product benfits and considerations to implementation.

Uniflair
Close Coupled Cooling
Chillers and Heat Rejection
As we look at the core cooling products within Room cooling Uniflair and EcoBreeze are the two main product families. Our close coupled cooling products consist of the complete InRow product line. When looking at the Uniflair and InRow products we must consider the entire system, requiring the use of chillers for chilled water based systems, and condensers or dry coolers for direct expansion systems.
The focus of this positioning is to understand the differences between these complete systems.

Room Cooling
Working within the IT environment we recognize that customer will operate there data centers at a wide range of rack densities. While close coupled cooling with InRow has typically been the product of choice for high density. We can not ignore the applicability of room based cooling systems when coupled with air distribution solutions like hot aisle containment, active floor, air removal systems, ect….
The use of the air distribution products enables room based cooling systems to not only achieve high density but also improves efficiency.
You can see from this chart that in all cases containment is recommended as densities increase for all systems. In fact for EcoBreeze containment is recommended at all densities in order to maximize the use of the economizer (free cooling) operating mode.
We will discuss the advantages containment offers a little later in this presentation.

5. Cooling Product Positioning

Operating Cost
3 Year TCO (Operating + First Cost)
Facility Constraints (Existing Data Centers)
Out of Capacity
Stranded Capacity
Out of Space
Qualitative Criteria
Predictability
Flexibility
Scalability
For this product positioning we looked at three key elements. Financial, Facility Limitations for existing factilities), and qualitiative criteria.
From the financial side we considered first cost, operating cost (efficiency) and three year TCO (operating cost + fist cost). While the life cycle of a typical data center is 10 years we chose a 3 year window for TCO due to the fact that most customers are looking for more immediate returns on products that show higher efficiency.
The challenge with existing facilities are the constraints of that particular site. Most existing sites will need to be looked at on a case by case basis. However, there are some basic guides we can provide based on the state of their existing system. The three main areas to consider in an existing facility is whether or not the facility is out of cooling capacity or has stranded cooling capacity. (Stranded capacity of a cooling system means that the cooling system is not operating at it’s capable capacity, making it stranded)
There are many features about the different cooling products that are less quantifiable and as a result there are many qualitative criteria to take into consideration when selecting the proper cooling product. For example – predictability, flexibility, and scalability are just a few. These benefits are highlighted for each of the products along with the consideration to implementing to provide some guidance on where to begin given these qualitative criteria.

Overall 3 Total cost to make recommendations on where to start
As a result of the financial comparison there were four key outputs. (See Slide bullets for the list of these outputs)
Slide Build: It is important to point out that this positioning is intended to be a guide to give the customer a place to start when considering a cooling system for his/her data center.
“This is a Guide, NOT a Gospel”

8. Benefits of Containment – Row Cooling
First Cost
Increased Capacity and Improved Capture Index
Reduced Equipment and Installation costs
Operating Cost
Reduced number of units operating at elevated utilization (increased fan speed)
Fixing the number of cooling units between open and HAC further increases efficiency
Includes Unit fan power, chiller, and pumps 1% 7% 5%
The first area explored in the financial comparison was the overall financial benefit containment provides. In this slide we quantify the benefits for row based cooling based on a 480 kW data center, based in St. Louis, MO.
In this scenario we were able to reduce the number of cooling units in the scenarios using HACS. The physical barrier of the containment system allows us to minimize the number of InRow in a given configuration because it improves the ability of the InRow units to effectively capture more air from adjacent racks. While at the same time boosting cooling unit capacity. As a result we are able to achieve a first cost savings when using hot aisle containment over an uncontained system. For this particular comparison the first cost was lower for the contained system under all densities considered. The difference in first cost varyed based on density, but we were able to achieve anywhere from 5 to 7% difference in first cost from using a contained vs. uncontained(Note: The relative cost show is $/Watt.)
The same is true for operating cost. By adding containment not only were we able to reduce the number of cooling units in the configuration we were able to save energy. It is important to note that the savings in energy increases as the density increases. This is why we typically recommend hot aisle containment for higher density applications.
In the end when using row based cooling with hot aisle containment will yield a financial benefit to the customer over an uncontained system. 7%

Note: This slide as 1 Build
Initial Slide:
Room based cooling systems also experience similar to benefits to Row cooling when using containment. In this scenario the number of room cooling units were fixed, as a result the first cost of the systems with containment are shown to be higher than the system without.
You will notice on the first cost chart uncontained, Cold Aisle, and Hot Aisle Containment are all considered. The cost of the cold aisle contained system is 6% cheaper at lower density than hot aisle containment. This is due to the cost of the drop ceiling (or ducting) that is required for HAC. However you will notice at the higher densities (12 and 20 kW) the first cost of the cold aisle containment system increases (10% and 7% higher at 12 and 20 kW per rack respectively). The reason for the increase in cost is the addition of active floor tiles. (Note: When using cold aisle containment all of the airflow delivered to the servers comes directly from the raised floor. As a result, in order achieve the airflow required by the servers at higher density, active floor tiles are used to control the amount of air coming from the raised floor. An active floor tile has a fan that controls the flow of air supplied to each rack in the contained aisle. The cost of the active floor tiles is what drives the first cost up at higher density.)
Build 1:
When adding containment to a room cooling system this scenario shows a 12% reduction in annual energy when compared to traditional room based cooling with raised floor. You will notice for the higher density scenarios the operating cost for hot aisle containment is slightly better (4% at 20 kW per rack) than the cold aisle containment. The difference in efficiency between the hot and cold ailse containment is the energy required for the active floor tiles.
Note: For each calculation there is a different quantity of racks, being the nominal cooling capacity of the datacenter fixed. (160 racks, 3kW / rack) 7%

10. Containment Recommendations
Always use containment for optimal TCO
Payback is immediate with close coupled cooling
3 year ROI for Room Based Cooling improves with density
Hot Aisle Containment preferred approach for new data center builds
Improved Efficiency of the Cooling System
Flexibility to keep data center cool.
Cold Aisle Containment – Retrofit for existing data center
Flexibility to adapt to existing room cooling systems
Active floor to assist with cold air distribution from raised floor to ensure sufficient air flow is available in contained aisle.
Efficiency Gains Require elevating room temperature
When considering a new data center build it is Schneider-Electric’s recommendation to always consider using containment for optimal TCO. Payback in many cases can be immediate and is typically realized within a 3 year time frame for most applications.

When comparing the core products we looked at the differences in efficiency across various size facilities. The information presented on this slide shows the differences in efficiency for small, medium, and large facilities assuming all systems operating at 6 kW per rack. The incremental savings in annual energy consumptions is reflected in the green arrows. So for example when looking at a small data center/IT load the annual energy improvement going from Uniflair to InRow is 12% which translates to a difference in partial PUE’s shown.
In this scenario the efficiency for the medium and large data center for Uniflair and InRow cooling products were effectively the same, while EcoBreeze provides a 12-18% reduction in annual energy consumption.
Free-cooling chillers are the same for both the chilled water solutions, i.e. InRow and Room cooling.

When considering first cost the costs per normalized to 1 based on the lowest first cost solution of Uniflair. Comparatively you can see the relative cost basis of the InRow and EcoBreeze systems. You notice as the size of the data center increases the cost of InRow increases as a result of the number of cooling units and piping infrastructure
The relative cost for EcoBreeze goes down as the facility gets large due to the large capacity of the EcoBreeze.

Differences between the solutions are sometimes very marginal so the diagram is a general guideline from 3-years TCO point of view
When looking at all of these scenarios it was found as discussed previously that containment does provide the overall best TCO. No matter the density InRow cooling provided the best 3 Year TCO for smaller IT Loads, Uniflair for Medium and EcoBreeze for Large.
As previously shown UniFlair room cooling provides the lowest first cost, however the efficiency advantages of InRow provides a favorable 3 Year ROI for smaller installations and EcoBreeze provides a favorable 3 Year ROI for large facilities. 5 10 12 15 20 25

Note: This Slide has 3 Builds:
Initial Slide: Looking at where our core products are typically applied we see these products fit a wider range of applications for other reasons besides the 3 year TCO shown on the previous slide. We definitely see an overlap in where products are applied and it will depend on many different factors like predictability, modularity, scalability, flexibility, Green, ect…
(Build 1) – InRow : When we look at the applicability of the InRow product. Smaller facilities and IT Loads does tend to be the dominant application. However, we see InRow applied in medium and large data centers as well. The main driver behind this is related to rack density and the scalability the product has as part of an ISX Solution. For higher density loads customers prefer the predictability of the close coupled approach and integrated rack and row level temperature control. This why we see many customers choose this solution over others for higher IT loads. In many larger facilities the InRow may be there only to supplement the higher density loads while room cooling is used as the main cooling system for the entire data center.
(Build 2) - Uniflair: The Uniflair product is not only seen in medium data centers, but definitely extends into both small and large facilities especially at lower densities. The flexibility of the raised floor and room level temperature and humidity control make it a very flexible solution to enable data center operates to get some cooling anywhere in the room. The low first cost of this solution certainly makes it attractive for those customers focused on initial investment.
(Build 3) – EcoBreeze: The large capacity of the EcoBreeze makes it suited more for the large facilies. However, customers looking for the highest efficiency, and those concerned about being Green and CO2 emissions are looking to the EcoBreeze in Medium sized facilities as well. EcoBreeze performs especially well at higher densities where delta’s T of the servers are elevated enabling increase hours of Economization. 5 10 12 15 20 25

IT Load to be
Deployed
One area that requires special consideration is existing data center facilities. There are many variables that will impact what solution to use in an existing facility. This recommendation assumes the existing facility is using a raised floor with room based cooling units.
This chart provides a guide line on what solution to consider based on the density of the IT load being deployed and the availability of cooling capacity in the existing facility. If the facility is out of capacity and looking to deploy lower density racks and has an existing raised floor or room cooling air distribution system. Adding additional room cooling units to handle the load is recommended.
If the facility has stranded cooling capacity it is recommended to implement cold aisle containment to isolate hot and cold air streams and boost the return temperature to the CRAC/CRAH units.
For existing facilities that are out of capacity and looking to deploy higher density loads. Close Coupled cooling with InRow is recommended. More information on deploying high density zones in existing data centers can be found in White Paper 134.
In cases where capacity is stranded and high density loads are being deployed Cold Aisle containment can be supplemented with Active floor titles to ensure sufficient air flow is delivered from the raised floor to higher density racks. Another option for high density may be to consider capturing hot air from high density racks and ducting it back to the existing cooling system using either an ARU (Air Removal Unit) or Ducted Rack (Vertical Exhaust Duct). (Note: With the VDE you must ensure the existing cooling system has enough external static pressure to handle the restriction of the duct connected to the rack. Otherwise there is a risk of over heating servers.
EcoBreeze May be challenging for Existing Facilities and will need careful evaluation
