Cooling Optimization 101: A Beginner's Guide to Data Center CoolingUpsite Technologies
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.
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.

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.

CALIENT’s LightConnect™ Fabric is a new approach to improving server and storage utilization rates in data centers. It achieves this by allowing Pod resources to be flexibly shared and reassigned at the optical layer in response to the needs of workloads.
This is achieved through a new virtual Pod or V-Pod architecture. In a typical V-Pod, some resources are static while others are dynamic – connected through OCS-enabled LightConnect™ Fabric paths to the spine switches rather than directly or through manual patch panels.

The Use of Ceiling Ducted Air Containment in Data CentersSchneider Electric
Ducting hot IT-equipment exhaust to a drop ceiling can be an effective air management strategy, improving the reliability and energy efficiency of a data center. Typical approaches include ducting either individual racks or entire hot aisles and may be passive (ducting only) or active (include fans). This paper examines available ducting options and explains how such systems should be deployed and operated. Practical cooling limits are established and best-practice recommendations are provided.
Exceeding the Limits of Air Cooling to Unlock Greater Potential in HPCinside-BigData.com
In this deck from the Perth HPC Conference, Werner Scholz from XENON Systems presents: Exceeding the Limits of Air Cooling to Unlock Greater Potential in HPC.
"A decade ago, 100 watts per CPU was devastating to thermal design. Today, Intel’s highest performing CPUs (e.g. Intel Cascade Lake-AP 9282 processor) have a thermal design envelope of 400 watts. There really is no end in sight, and accommodating more power is critical to advancing performance. The ability to dissipate the resulting heat is the hard ceiling that systems face in terms of performance – giving greater importance to liquid cooling breakthroughs. With liquid cooling, less energy is expended to cool systems – a significant savings in HPC deployments with arrays of servers drawing energy and generating heat. Electrical current drives the CPU and enables it to function. This electrical power is converted into thermal energy (heat). To maintain a stable temperature, the CPU needs to be cooled by efficiently removing this heat and releasing it. Liquid cooling is the best way to cool a system because liquid transfers heat much more efficiently than air. From an environmental perspective, liquid cooling reduces both those characteristics to create a smarter and more ecological approach on a grand scale. The cascade of value continues, as ambient heat removed from systems can then be used to heat buildings and augment or replace traditional heating systems. It’s an intelligent approach to thermal management, distributing the economic value of reduced energy use and transforming heat into an enterprise asset."

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.
One of the most critical aspects of traditional data center infrastructure is cooling system optimization and planning. When a subset of the system is physically relocated closer to the end user, as described in the Edge Data Center (EDC) concept, a solution to provide a data center-like environment for high-power equipment in public places such as office buildings, shopping centers, school campuses, event arenas, and wireless cell sites will be required.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Design – Your
Layout Can Save or
Kill Your PUE &
Cooling Efficiency
The following data center upgrade proposal
demonstrates how floor layout has a major
impact on data center performance.
Implementing best practices and validating
those practices through CFD models allowed
Great Lakes to suggest a new layout that
would provide an improved PUE, cooling
costs reduction, and increased ROI.
Jason Hallenbeck, DCDC, explains the
concepts behind how data center floor
design can save or kill your PUE and
cooling efficiency—as found in this
proposal. Find Jason presenting

Executive Summary
Great Lakes began a recent dialogue with a customer regarding current operations and the potential for performance
improvement within the customer data center.
After a series of initial conversations, the customer expressed a desire to gain an assessment of the current
operational status of the company’s data center, along with data center infrastructure management (DCIM)
recommendations which could provide multi-generational support as the company’s IT needs continue to evolve.
Great Lakes Case & Cabinet was contracted to provide a comprehensive evaluation of the customer’s Data Center
and to conduct complete computational fluid dynamics (CFD) analysis of the facility in its current form. Numerous site
visits were conducted and numerous on-site measurements were taken. The operational capabilities of the current
data center were captured in a CFD to establish baseline standards against which any potential future improvements
might be measured.
Great Lakes was also asked to look at the short, medium and long term potential for increased density within the
data center as well as an expansion of IT operations within the space. As part of that effort, Great Lakes would offer
infrastructure recommendations, supported by CFD analysis which would create real world performance estimates of
future operations within the data center, as those recommendations might be implemented.
The following pages outline the scope of work performed by Great Lakes as well as the presentation of data
collected, infrastructure recommendations made to the management of the data center (along with estimates and
ROI for recommended solutions) as well as CFD modeling designed to estimate data center performance conditions
as those recommendations might be implemented.

Under-floor (Baseline)

Entrance
With the under-floor plenum installed, the secondary zone created is highly pressurized.
In addition, there is minimal to no load in the secondary zone. This greatly reduces the
efficiency of the two CRAC units installed in the zone. It is recommended that this barrier
be removed to allow the two units to supply additional cooling to the entire room.

Under-floor (Phase 1)

With the plenum barrier removed, the CRAC units airflow from the secondary zone can travel to the
entire data center supporting IT loads where needed. This is especially significant when utilizing
cold aisle containment. With the cold aisle contained the proximity of the CRAC unit in a data center
to the load becomes less critical. Every unit in the data center can supply conditioned air to the
entire facility. In the event of unit(s) failures(s) provided that the overall cooling capacity does not fall
below the IT load the equipment will continue to operate without interruption. This increases uptime
by reducing the criticality of any one unit, and makes unit maintenance more manageable.

Tile Migration

Tile migration for phase 1 development. By removing tiles in the hot aisle and locations not directly
near IT equipment the under-floor pressure increases creating a higher velocity of airflow to the
equipment providing better cooling. In addition, by reducing the amount of conditioned air mixing
with exhaust air the return temperature to the CRAC units increases which increases the efficiency
of the entire HVAC system.

Baffles reduce recirculation by directing conditioned air toward the intake side and exhausting the hot air toward the cold aisle. Used
in conjunction with a brush grommet kit, side-to-side airflow operates efficiently in a hot aisle/cold aisle configuration.

CRAC Unit Failure Analysis: Baseline
207
90.1°F Temp
When the CRAC unit with the highest load on it (conditioning the most air in the data center) is
shutdown, the hot air from the server farm (specifically the blade server enclosures) travels to
the next nearest unit. This increases the load on that unit as well as increases the cold aisle
temperatures. This scenario creates massive short cycling of hot air, increasing the
equipment intake temperatures, resulting in equipment “thermal-ing down/off” or failing.

CRAC Unit Failure Analysis: Phase 1
207
When cold aisle containment is implemented and the CRAC unit is shut down the hot air
continues to travel to the nearest available unit. However, with the cold aisle contained a
consistent flow of conditioned air is supplied into the aisle equipment intakes; no hot air short
cycling can occur, resulting in uninterrupted service in the event of a single unit failure.
Temps taken at enclosure 508 show a delta of 8 degrees Farenheit. In addition temps taken in
the cold remain a consistent
60-63 degrees F.

Conclusion
Great Lakes has designed and modeled a solution that provides the customer with a data center upgrade plan
designed to increase the energy efficiency and reliability of their current design by segregating hot and cold air
optimizing air delivery, and deploying cold aisle containment.
Recommendations:
1. Adjust the floor tiles providing airflow to the enclosures at the network core. Moving the tiles directly in front of
the enclosures will allow a greater supply of conditioned air to reach the equipment, greatly improving the
exhaust temperature of the airflow equipment installed in the racks and lowering the internal enclosure
temperatures. This effort will result in a decreased risk of thermal issues: performance degradation, thermal
shutdown, and early equipment
mortality.
2. Create and fully contain the cold aisles in the server farm. This can be achieved in several steps: redeploying
and consolidating floor tiles; completing the aisles with enclosures; installing filler panels in any unused RMU;
and containing the cold aisle through the use of end of row doors and overhead containment panels.
Through containment, the conditioned air is segregated from hot exhaust air. Contained conditioned air will remain at
delivered temperature until used by the equipment. Another advantage of cold aisle containment is consistency in
cold aisle temperatures which will be very close to the supply temperatures of the CRAC units. Any increase to the
set points of the CRAC unit should proportionally increase the conditioned air supplied to the cold aisle. This should
make it much easier to the deliver a consistent supply temperature to every piece of equipment.
Modeling revealed that the removal of the under floor baffle could increase the amount of cooling capacity to the
entire room. A fully open raised floor, in conjunction with cold aisle containment, could reduce the impact a single
CRAC unit failure will have on the data center. This scenario was modeled at the CRAC unit with the highest load in
the server farm. Hot aisle temperatures increased dramatically, while the cold aisle remained at supply temperatures.
