As new personnel enter the industry, they are often bombarded with a slew of buzz words and marketing messages that would lead them to believe that data centers almost run themselves. And while monitoring and DCIM solutions are improving the management of power and cooling, an understanding of the fundamental science is crucial to both see through the hype and get the most out of management systems. More so, as the veterans in our industry start to retire, much of the basic knowledge around power and cooling is often overlooked when training their successors. This session will provide that basic knowledge and give a fundamental understanding of the power and cooling infrastructure in a data center, with an emphasis on cooling optimization. In this session, you’ll learn how to recover stranded cooling capacity, reduce operating costs, improve IT equipment reliability, and prolong the life and capacity of the data center.

The topic of raising temperatures in data centers used to be met with much criticism in the industry, but in recent years has become more accepted. A big driver for this acceptance has been ASHRAE’s expanded envelope for recommended and allowable server inlet temperatures. However, while this has eased the discussion, there are still some questions that have been left unanswered. What’s the difference between recommended and allowable? Which one is best to use? What steps must be taken to safely raise set points? How do you ensure servers are still adequately cooled? What if you have different server types (A1, A2, A3, A4)? This presentation will examine these questions to give a clearer understanding of ASHRAE’s recommended and allowable guidelines. Also covered will be an explanation on how, in some cases, it is possible to raise cooling control set points without raising server inlet temperatures.

When developing data center energy-use estimations, engineers must account for all sources of energy use in the facility. Most energy consumption is obvious: computers, cooling plant and related equipment, lighting, and other miscellaneous electrical loads. Designing efficient and effective data centers is a top priority for consulting engineers. Cooling is a large portion of data center energy use, second only to the IT load. Although there are several options to help maximize HVAC efficiency and minimize energy consumption, data centers come in many shapes, sizes, and configurations. By developing a deep understanding of their client’s data center HVAC requirements, consulting engineers can help maintain the necessary availability level of mission critical applications while reducing energy consumption.
Determining your data center strategy is critical in this expanding world of big data, cloud and mobility. Should you build your own data center, consider a wholesale arrangement, colocate with another carrier or transfer your critical information to the cloud? Or, does some combination of these options best suit your needs? Where do you even begin when planning these large enterprise decisions?
Join Randy Ortiz, VP of Data Center Design and Engineering, from Internap as he breaks down the steps you need to take to achieve a successful outcome for your data center initiatives.

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.
The data center market has expanded dramatically in the past few years, and it doesn’t show signs of slowing down. Many clients and building owners are requesting modular data centers, which can be placed anywhere data capacity is needed. Modular data centers can help cash-strapped building owners add a new data center (or more capacity) to their site, and can assist facilities with unplanned outages, such as disruptions due to storms. Owners look to modular data centers to accelerate the “floor ready” date as compared to a traditional brick and mortar.
The segmentation of data centers into alternating hot and cold aisles is an established best practice. A number of manufacturers are taking this premise of airflow separation a step further by marketing "containment" solutions. By containing the hot or cold aisle, the air paths have little chance to mix, presenting data center operators with both reliability and efficiency gains.

4 steps to quickly improve pue through airflow managementUpsite Technologies
It’s well known that cooling typically accounts for around half of a data center's total power consumption. Given this, it's imperative that cooling is optimized to achieve a low Power Usage Effectiveness (PUE). While this too may be common knowledge, the question still remains, how can this be done quickly, with all possible benefits realized, and with the fastest return on investment?
One of our most popular webinar presentations on data center cooling: 2007 Data Center Cooling Study: Comparing Conventional Raised Floors with Close Coupled Cooling Technology.
If you're looking for a solution, it's simple physics: Water is 3,500 times more effective at cooling than air. But, liquid cooling carries a large stigma particularly because of the large price tag. And, if you're like other Data Center Managers, the words of Jerry McGuire may be ringing in your head "Show me the money!"

One word that you often see associated with any data center is its “tier,” or its level of service. Virtually every data center has a tier ranking of I, II, III, or IV, and this ranking serves as a symbol for everything it has to offer: its physical infrastructure, its cooling, power infrastructure, redundancy levels, and promised uptime.
This presentation takes a look at each of the 4 data center tiers, examining the key components for each tier, as well the total expected uptime level for each tier. If you are in the process of evaluating data centers, this is no doubt a term you will come across in your search, so we hope this presentation helps provide some solid background in to how you can better choose a data center for your specific needs.

For Most Data Centers, Liquid and Air Cooling Will Not be Mutually ExclusiveUpsite Technologies
A recent report from Technavio indicates that the adoption of liquid-based cooling is high, as it is considered more efficient than air-based cooling. Globally liquid-based cooling is expected to grow at a remarkable rate through 2020, posting a CAGR of almost 16% during the forecast period. So, why is this level of adoption happening? Increasing rack densities lead by high performance computing (HPC) and the quest to improve efficiency are driving an increase in liquid cooling design strategies and deployment. While still relatively sparse, liquid cooling will become more prevalent, but this does not mean the end of air cooling. In this session, we’ll discuss how to implement liquid cooling while maintaining appropriate air-cooling conditions and fully realize efficiency gains. Lastly, we’ll discuss how to get started and get ahead of the market when it comes to improving cooling efficiency.

Data Center Cooling Efficiency, Optimization and Trade-offs
Learn how to lower Cooling costs 30-80% while increasing sustainability.
Gain insight on advantages and the trade-offs of the many technologies, where combinations of technologies may be best, and learn how cooling solutions play into the upcoming Title 24 Code changes.
From Best Practices, Containment (Hot vs. Cold, Passive vs. Managed, Chimney’s and IT Rows), Demand Based Cooling (Managed Distribution), new High Efficiency In Row Cooling (close coupled) technologies (CMS designs = 40% - 60% more efficient), new High Efficiency CRAC/H’s (CMS designs = 40-50% more efficient).
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.
Eliminating Data Center Hot Spots: An Approach for Identifying and Correcting Lost Air
Data center cooling is a hot topic. But, when you consider the challenges associated with cooling the latest generation servers, the growing cost of infrastructure equipment, and the risks associated with data center hot spots brought on by high-density clusters and premature hardware failure, it's easy to understand the focus.

Strategies for Re-Using Data Center Heat Energy and Their Impact on PUE (Both...Upsite Technologies
Is it possible to recycle some data center energy to achieve a PUE less than 1.00? The simple answer is no. However, over the years, such claims have been made and are invariably followed by wise nods, knowing winks, and comments such as, "Well, somebody doesn't understand PUE basic math."
While striving for a PUE of less than 1.00 undoubtedly gets us into the realm of physics-defying fantasy, that does not however mean there is no value in recycling the heat energy produced by our ICT equipment. After all, we have already recognized the great value in actually increasing PUE by dramatically reducing the divisor of our PUE equation through virtualization, turning off comatose servers, migrating from Windows to Linux, etc.
The PUE rock showing above the water level may be bigger, but the sea level itself is lower (hence, the ongoing discussion for new and improved metrics). Such is the case with looking for ways to perform useful work with the thermal energy produced by ICT equipment. While we may not give ourselves a bragging-rights PUE decimal fraction, perhaps we can improve our organization's bottom line and contribute positively to the planet's health. This session will explore five strategies for re-using data center heat energy while discussing their impacts on PUE, the bottom line, and the environment.
Key takeaways:
- Learn about the different strategies that are available to re-use (recycle) heat energy produced by ICT equipment.
- Understand the relationship between recycling data center heat energy and resultant impacts on PUE.
- Learn about the benefits of recycling data center heat energy for your organization's bottom line and the environment.
Data Center Monitoring and Management Best Practices: How You Can Benefit fro...Upsite Technologies
As data centers have adapted to many changes over the past year, managing sites with limited on-site personnel has become a new challenge. Because of this, a renewed focus by data center managers has been placed on remote monitoring and management solutions to help ensure operations continue to run as efficiently as possible. And while legacy monitoring and DCIM solutions provide some resolve to this issue, ever-changing needs and requirements by data centers are driving much change and innovation in this segment of the industry. This session will examine the software solutions that are currently available to remotely monitor and manage data center operations, with an emphasis on the power and cooling infrastructure. We will also examine emerging technologies like artificial intelligence, machine learning, and virtual reality as well as new concepts like DMaaS, and discuss how they are changing the landscape of data center monitoring and management. This analysis will take many factors into consideration including, real-time thermal performance, airflow management, power consumption, risk mitigation, and cooling optimization.
How IT Decisions Impact Facilities: The Importance of Mutual UnderstandingUpsite Technologies
Decisions and actions typically under the jurisdiction of the IT side of data center management can have a profound impact on the mechanical systems and resultant operating costs and capacity of the data center. By understanding these impacts, IT and facilities management are able to develop a cooperative approach to managing the data center, resulting in a more effective and efficient operation, thereby reducing operating costs.

Study of data centers reveals the average computer room has cooling capacity that is nearly four times the IT heat load. When running cooling capacity is excessively over-implemented, then potentially large operating cost reductions are possible by turning off cooling units and/or reducing fan speeds for units with variable frequency drives (VFD). Using data from 45 sites reviewed by Upsite Technologies, this presentation will show how you can calculate, benchmark, interpret, and benefit from a simple and practical metric called the Cooling Capacity Factor (CCF). Calculating the CCF is the quickest and easiest way to determine cooling infrastructure utilization and potential gains to be realized by AFM improvements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

“Power In, Heat Out Always” – Ken Brill
• Every kW of power consumed by any equipment in a computer room becomes a kilowatt of heat that needs to
be removed
• Therefore, the total power being demanded by IT equipment (i.e. total UPS output load) provides a good
indication of the cooling capacity required
7. datacenterworld.com
The Goal of Airflow Management and Cooling
Optimization
• Provide appropriate IT equipment intake air conditions and redundant cooling capacity, with the lowest
possible flow rate of conditioned air at the warmest possible temperature
8. datacenterworld.com
What is Airflow Management?
• In a standard data center environment that is cooled by air, airflow management is simply the process of
managing the flow of air through the room
• Specifically, managing the flow of conditioned or cooled air to the intakes of IT equipment and the flow of
exhaust air back to the cooling units
• There are many configurations for IT equipment layout and cooling system designs, in all cases airflow
management is simply preventing the hot and cold airstreams from mixing
• On its own, improving airflow management can reduce IT equipment intake air temperatures which improves
IT equipment reliability
• It also enables the adjustment of cooling controls and set points to reduce operating costs, improve cooling
capacity, and defer capital expenditure

How Airflow Management Relates to PUE
• There is a direct relationship between airflow
management and PUE – the better the airflow
management, the better the PUE
• Mechanical cooling + fan cooling is 35% of total
load and 73% of non-IT load
Total Load
IT Load
PUE = = 1.92

Bypass Airflow
• Bypass airflow is any conditioned air from a cooling unit that does not pass through IT equipment before
returning to the cooling unit
• The total volumetric flow rate of conditioned air through cooling units is independent of the volumetric flow rate
of air through IT equipment
• Bypass airflow (cfm) = Total cooling flow (cfm) – Total IT equipment demand flow (cfm)
17. datacenterworld.com
Bypass Airflow Clarified
• This figure shows typical airflow patterns before
airflow management
• The arrows near the bottom of the cabinets
represent bypass airflow through unsealed cable
openings
18. datacenterworld.com
Exhaust Air Recirculation
• Exhaust air recirculation is any air that passes through IT equipment more than once before returning to a
cooling unit
• This is when warm exhaust air mixes with the cold supply air and raises the intake temperatures possibly
causing hot spots and reducing IT equipment reliability
• Exhaust air recirculation limits the reduction of fan speed and the raising of supply temperatures during cooling
optimization efforts
19. datacenterworld.com
Exhaust Air Recirculation
• There are four areas where exhaust air
recirculation can occur:
• Around the end of cabinet rows
• Over the tops of cabinets
• Through the cabinet
• Underneath cabinets
20. datacenterworld.com
The Four Delta T’s (ΔT)
• Delta T (ΔT) = Change in temperature
• There are four different ΔT’s which contribute to the health of the data center
• Two of these temperature differentials are well known, however there are two additional ΔT’s that are not well
known and rarely considered, yet they are crucial to improving airflow management and reducing energy
consumption
21. datacenterworld.com
The Four Delta T’s (ΔT)
1. Though IT equipment
2. IT equipment exhaust to cooling unit
3. Through cooling unit
4. Cooling unit supply to IT equipment intake
22. datacenterworld.com
The Four Delta T’s (ΔT)
• In most data centers the greatest loss of
efficiency is having a low temperature of air
returning to the cooling units
• The goal is to always have the highest
possible return air temperature to cooling units
24. datacenterworld.com
A Holistic Approach to Airflow Management
• With so many variables affecting airflow within a data
center, it can be daunting to know where to start and how to
get the most out of airflow management improvements
• The 4 R’s of Airflow Management™, developed by Upsite
Technologies, is a holistic methodology for identifying and
implementing changes to optimize the data center’s cooling
infrastructure and realize energy savings
• The 4 R’s are: the Raised Floor, the Rack, the Row, and the
Room
25. datacenterworld.com
Rack Airflow Management
• Managing airflow through the vertical plane across
the face of IT equipment intakes is “Rack AFM”
• Sealing the open space of a rack often provides
the greatest return on investment of any AFM effort,
both in the ability to reduce hot spots and the ability
to reduce energy consumption
26. datacenterworld.com
Rack Airflow Management Best Practices
• Install blanking panels in every open U space
• Seal the space between mounting rails and sides of cabinets
• Identify IT equipment mounted to the back rails, commonly switches, that do not have ducted inlets to the face
of the cold aisle and fix with passive cooling channels
• Identify IT equipment facing backwards, inlet facing hot aisle and exhaust blowing into the cold aisle, and
rotate equipment if possible
27. datacenterworld.com
Raised Floor Airflow Management
• Managing airflow through the horizontal plane of
the raised floor is “Raised Floor AFM”
• There are two aspects to raised floor AFM:
• Sealing all openings in the raised floor other
than supply tiles
• Managing the type, location, and number of
supply tiles
• Raised floor AFM ensures that the cooling capacity
in the room is properly delivered to the cold aisle
28. datacenterworld.com
Raised Floor Airflow Management Best Practices
• Seal cable openings with brush grommets
• Seal openings around the perimeter of the room
• Seal openings in the perimeter walls below the raised floor or around partitions
• Make sure all supply tiles are properly located in front of IT equipment and remove any tiles that are not
supplying cooling air to IT equipment
• Ensure supply tiles are the appropriate size in terms of % open area
29. datacenterworld.com
Row Airflow Management
• Improving cold aisle and hot aisle separation at the
row level is “Row AFM”
• After improving AFM at the rack and raised floor
levels, evaluating the air distribution in rows is the
next step in AFM and reducing energy consumption
• This generally involves installing doors on either
the ends of hot or cold aisles and baffles or a full
roof over the aisle
30. datacenterworld.com
Row Airflow Management Best Practices
• Block open spaces underneath racks to prevent air flowing under the cabinets
• Seal spaces in cabinet rows where there are missing cabinets or gaps between cabinets
• Install aisle end doors on either the hot or cold aisles
• Install top-of-rack containment (partial or full) on either the hot or cold aisles
31. datacenterworld.com
Room Airflow Management
• Changes at the room level are required to realize
the benefits of implementing the AFM improvements
listed above
• “Room AFM” refers to optimization of the cooling
infrastructure and is the only way to realize energy
savings from AFM improvements made at the Rack,
Raised Floor, and Row levels
• This is referred to as cooling optimization
32. datacenterworld.com
Room Airflow Management Best Practices
• Raising cooling unit air temperature set points as high as possible without exceeding the maximum allowable
IT equipment intake air temperature
• Reduce fan speeds for units with variable frequency drives (VFD) as much as possible without exceeding the
maximum allowable IT equipment intake air temperature
• Expand the allowable relative humidity (Rh) band to prevent cooling units from fighting each other, and the
energy consumption required for humidification
• Turn off excess cooling units when possible
34. datacenterworld.com
What is Cooling Optimization?
• Cooling optimization is the process of making adjustments to the cooling system controls to improve energy
efficiency resulting in reduced operating costs, improve cooling capacity, improve IT equipment reliability, and
defer capital expenditure
• Cooling optimization is often an iterative process of making adjustments to controls, allowing the system to
equalize, and then making additional adjustments, and so on
• Each time additional airflow management improvements are implemented, or significant IT equipment
changes occur, there are opportunities for refining the cooling optimization
35. datacenterworld.com
Why is Cooling Optimization Important?
• After any significant airflow management improvement or IT load installation or removal, there’s an opportunity
to evaluate room level controls to ensure efficient operation and sufficient redundant capacity
• Without cooling optimization, every airflow management improvement that has been made is an expense
• Cooling optimization is the only way to achieve a return on investment from airflow management
improvements
• Efficiency can not be purchased, it has to be managed
38. datacenterworld.com
How Cooling Optimization Works
• This figure shows typical airflow patterns after both
airflow management and cooling optimization
• Conditioned airflow supplied by the cooling unit
has been reduced by 50% (from 10 units to 5 units)
