Six Reasons Why Modular Power and Cooling Plants Will Make Traditional Data Center Designs Obsolete

Posted by on April 22, 2012  |  No Comments

Neil Rasmussen (Senior Vice President of Innovation, IT Business for Schneider Electric) delivers keynote presentation that asserts that many traditional data centers are inefficient, costly and incompatible with high density IT deployments, and that pre-engineered and pre-manufactured power and cooling subsystems based on standardized modules can provide optimized and predictable performance faster and at lower cost.

Six Reasons Why Modular Power and Cooling Plants Will Make Traditional Data Center Designs (Click Here To Download Green Data Center Conference Presentation)

Presentation Highlights Delivered by Neil Rasmussen:

Traditional data center defined:

  • Power and cooling devices from various manufacturers are integrated for a project
  • System performance is predicted by analysis
  • Controls are created for the project
  • Management software is customized for the project
  • Cooling is by CRAC/CRAH units located in the IT room
  • Air is distributed under floor via vented tiles
  • Outdoor heat rejection via dry cooler, condenser, or cooling tower

Modular power and cooling plants defined:

  • End-to-end power and cooling systems are pre-engineered and pre-manufactured
  • Standard building blocks are available
  • Modules may be internally fault tolerant, and can be combined to achieve redundancies
  • Equipment arrives in pre-packaged modules, such as skids, containers, or kits
  • System performance is guaranteed by spec
  • Controls are standard
  • Management software is standard for the modules

Reason #1: Economizer regulations

  • ASHRAE, LEED, and local regulations require economizer modes
    • Old model: Economizer assists mechanical plant, when possible
    • New model: Mechanical plant assists economizer, when needed
  • Maximization of free cooling is a complex design and control problem, difficult to achieve in a unique design
  • An integrated design, that considers IT supply temperatures and airflows, load factors, and ambient conditions is best achieved in a standardized, pre-engineered system

Reason #2: Dynamic power variation

  • Power management functions in IT equipment will play a major role in reducing overall energy use of data centers
    • Old model: Long term adaptations to slow changes in load
    • New model: Cooling plant optimizes for wide swings in IT load
  • Traditional plant design responds through interventions (moving tiles, turning equipment on and off, adding equipment)
  • An optimizing cooling plant adapts to changing load and airflow requirements by design

Reason #3: Speed of deployment

  • Modularity is not automatically faster
  • Modularity allows standardization. It is standardization that makes cycle time faster
    • Old model: 18 month design-build-commission cycle
    • New model: 4 month order-install cycle. Design is off-the-shelf. Systems mainly pre   commissioned.
  • Eventually standard power and cooling modules will be inventory items

Reason #4: Scaling requirements

  • Oversizing remains a major drag on the data center industry
  • It is the dominant contributor to energy inefficiency
  • It causes waste of CAPEX and OPEX
    • Old model: Build it now because it is too painful – slow – risky – burdensome – costly to adapt   later
    • New model: Modular design for scalability
  • Capacity can also be scaled to meet changes in power density and redundancy

Reason #5: Control & management system costs

  • Controls and management system cost in traditional data center is around $.50 -$1.50 per watt (under 10% of system cost)
  • To actually correctly engineer such unique systems for a traditional data center should cost about $5 per watt (nearly equal to expected system cost) if we
    • Optimized for energy savings
    • Did full testing under all operating and fault conditions
    • Documented the system fully
    • Embedded effective diagnostics
    • Did appropriate fault-tree and event-tree analysis
    • Designed to accommodate expected changes

Reason #6: Lower installed and operating costs
Extra installed costs

  • Container / skid / package costs
  • More smaller devices replace fewer larger devices

Installed cost savings

  • One-time engineering
  • Defer costs of capacity not yet required
  • Programming & configuration
  • Rigging
  • Documentation
  • Shipping / installing damage
  • Factory vs. field labor
  • Less field testing

Extra operating costs

  • None identified

Operating cost savings

  • Reduced expertise requirements
  • Energy costs
  • No maintenance costs on capacity not yet required

Conclusion

  • Standardized modular power and cooling plants have lower cost and better performance
  • Challenges such as dynamic power, economizer optimization, and high density will accelerate the end of traditional design approaches
  • Modular approaches to cooling plants just as effective for indoor IT rooms as they are for IT containers

Current “Educational Series For Data Center Professionals” Course Curriculum:

“POWER FUNDAMENTALS”-If you’ve ever asked yourself…”What’s the difference between kVA and kW?  AC and DC, isn’t that a band? Single-phase or three-phase?…then this is the course for you! In this course, students learn the fundamentals of AC and DC power, from generation to application.

“POWER DISTRIBUTION”-“With great power comes great responsibility.”  One can have all the power in the world but efficiently distributing that power to your critical equipment is the trick that makes the difference between business as usual or lights out!  In this course, students learn the fundamentals and application of efficient power delivered in terms of both off-site and on-site power generation.

“EFFICIENT POWER MANAGEMENT-OPTIMIZING TCO”- “Generator? Check. UPS? Check. Doors secured? Check. Red lights? Check…uh-oh! What do we do now? Who will we call?  Is this covered under a service agreement?” Managing your assets is one thing but doing so in a manner that lowers your TCO and allows you to sleep better at night takes some strategy.  Increasing availability and reliability while continuously decreasing costs means you’ll have to know when to break from the crowd and try less conventional methods.  This course is designed for the professional that has a solid understanding of both “Power Fundamentals” and “Power Distribution” and is ready to develop a strategy to manage their time, manpower and assets with maximum efficiency.

“CRITICAL COOLING 101-FUNDAMENTALS OF AIR CONDITIONING”-This course explains the fundamentals of air conditioning systems and how they can be leveraged in a data center to your advantage.  Topics include:  The Properties of Heat Transfer, The Ideal Gas Law, The Refrigeration Cycle, Condensation Control, and Comfort vs. Precision Cooling.  With a solid understanding of air conditioning principles, this course enables students to make knowledgeable decision on what air conditioning solutions are right for their data center-solutions based on fact, rather than sales and marketing strategy.

“EFFICIENT COOLING-OPTIMIZING COOLING STRATEGIES AND ARCHITECTURE”-Today’s servers generate significantly more heat, and in more concentrated, confined space than they did 20 years ago. So, why are data centers still using the same cooling strategies of yesteryear? This course takes a hard look at data center cooling architectures from many angles: efficiency, reliability, TCO, feasibility and availability, enabling students to make the best choices in cooling their critical equipment.  “Understanding the difference between comfort cooling and critical cooling; understanding the different types of cooling architectures and their deployment; and developing a method of choosing one cooling strategy over another” are all topics discussed in this course offering.

The “Breakfast and Learn Educational Series for Data Center Professionals” offers the data center community multiple opportunities to learn from their peers, share experiences, and expand industry knowledge.  Our educational sessions are conducted throughout the United States quarterly and will be advertised via our Data Center Critical Power and Cooling LinkedIn Group and/or follow us on Twitter.  Our “Breakfast and Learn Series” can also be customized and conducted at your own facility.  For more information on our “Breakfast and Learn Series” please contact us.

Current “Breakfast and Learn” Discussions:

“RIGHT-SIZING VERSUS OVER-SIZING: EFFICIENCY IN THE DATA CENTER”- Forecasting and measuring the total cost of ownership (TCO) for Data Center Physical Infrastructure (DCPI) is essential for return-on-investment (ROI) analysis.  Oversizing is the main contributor to excess TCO.  Oversizing creates inefficiencies in the data center including excess capital cost, operating cost, and specifically energy cost.  The average data center operator can achieve the highest return investment in relation to DCPI through right-sizing.  Right-sizing the DCPI system to the load is the key to optimizing TCO and has the most impact on DCPI electrical consumption.  Right-sizing can potentially eliminate up to 50% of the electrical bill in real-world scenarios.  For example, potential electricity cost savings for a typical 1 MW data center has been shown to be $2,000,000 to $4,000,000 over a typical 10-year life to the facility.  Data center efficiency is key to controlling your energy costs and should be a topic of significant importance to all data center operators.  This discussion is available through our “Breakfast and Learn Educational Series For Data Center Professionals”.

“IS PERIMETER COOLING DEAD?”-Traditional data center “room” cooling is unable to accommodate the latest generation of high and variable density IT equipment resulting in cooling systems that are inefficient, unpredictable, and low in power density.  To address these problems, row-oriented and rack-oriented cooling architectures have been developed.  Our presentation, “Is Perimeter Cooling Dead” examines and contrasts the 3 basic cooling approaches:  room, row, and rack architectures.  Each approach has an appropriate application but row-orientated cooling is emerging as the solution of choice for most next generation data centers.  Next generation data centers demand the flexibility, predicability, scalability, reduced electrical power consumption, reduced TCO and optimum availability that row and rack-oriented cooling architectures can provide.  Additionally, the factors that gave rise to the establishment and use of the raised floor is no longer justified or desirable.  To learn more about this topic, “Is Perimeter Cooling Dead” is available for your organization through our unique “Breakfast and Learn” Educational Series For Data Center Professionals.

Preventive Maintenance Strategy for Data Centers

Posted by on April 1, 2012  |  No Comments

White Paper 124

This white paper highlights data center power and cooling systems preventive maintenance (PM) best practices. Hands-on PM methods (i.e., component replacement, recalibration) and non-invasive PM techniques (i.e., thermal scanning, software monitoring) are reviewed. The industry trend towards more holistic and less component-based PM is also discussed.

The term preventive maintenance (also known as preventative maintenance) implies the systematic inspection and detection of potential failures before they occur. PM is a broad term and involves varying approaches to problem avoidance and prevention depending upon the criticality of the data center. Condition-based maintenance, for example, is a type of PM that estimates and projects equipment condition over time, utilizing probability formulas to assess downtime risks.

PM should not be confused with unplanned maintenance, which is a response to an unanticipated problem or emergency. Most of the time, PM includes the replacement of parts, the thermal scanning of breaker panels, component / system adjustments, cleaning of air or water filters, lubrication, or the updating of physical infrastructure firmware.

At the basic level, PM can be deployed as a strategy to improve the availability performance of a particular data center component. At a more advanced level, PM can be leveraged as the primary approach to ensuring the availability of the entire data center power train (generators, transfer switches, transformers, breakers and switches, PDUs, UPSs) and cooling train ACs, CRAHs, humidifiers, condensers, chillers).

A data center power and cooling systems preventive maintenance (PM) strategy ensures that procedures for calendar-based scheduled maintenance inspections are established and, if appropriate, that condition-based maintenance practices are considered. The PM strategy should provide protection against downtime risk and should avoid the problem of postponed or forgotten inspection and maintenance. The maintenance plan must also assure that fully trained and qualified maintenance experts observe the physical infrastructure equipment (i.e., look for changes in equipment appearance and performance and also listen for changes in the sounds produced by the equipment) and perform the necessary work.

“Preventative Maintenance Strategy for Data Centers” Full White Paper 124 (Click Here)

Executive Summary:

In the broadening data center cost-saving and energy efficiency discussion, data center physical infrastructure preventive maintenance (PM) is sometimes neglected as an important tool for controlling TCO and downtime. PM is performed specifically to prevent faults from occurring. IT and facilities managers can improve systems uptime through a better understanding of PM best practices. This white paper describes the types of PM services that can help safeguard the uptime of data centers and IT equipment rooms. Various PM methodologies and approaches are discussed. Recommended practices are suggested.

Contents:

  • Introduction
  • PM Outcomes
  • Evolution of PM
  • Evidence of PM progress
  • Why Physical Infrastructure Components Fail
  • Recommended Practices
  • PM Options

Conclusion:

PM is a key lifeline for a fully functioning data center. Maintenance contracts should include a clause for PM coverage so that the data center owner can rest assured that comprehensive support is available when required. The current PM process must expand to incorporate a “holistic” approach. The value add that PM services provide to common components today (such as a UPS) should be expanded to the entire data center power train (generators, transfer switches, transformers, breakers and switches, PDUs, UPSs) and cooling train (CRACs, CRAHs, humidifiers, condensers, chillers).

As of today, the PM provider in the strongest position to provide such a level of support is the global manufacturer of data center physical infrastructure. An integrated approach to PM allows the data center owner to hold one partner accountable for scheduling, execution, documentation, risk management, and follow up. This simplifies the process, cuts costs, and enhances overall systems availability levels.

“IS PERIMETER COOLING DEAD?”

Traditional data center “room” cooling is unable to accommodate the latest generation of high and variable density IT equipment resulting in cooling systems that are inefficient, unpredictable, and low in power density.  To address these problems row-oriented and rack-oriented cooling architectures have been developed.  Our presentation, “Is Perimeter Cooling Dead” examines and contrasts the 3 basic cooling approaches: room, row, and rack architectures. Each approach has an appropriate application but row-orientated cooling is emerging as the solution of choice for most next generation data centers. Next generation data centers demand the flexibility, predicability, scalability, reduced electrical power consumption, reduced TCO, and optimum availability that row and rack-oriented cooling architectures can provide. Additionally, the factors that gave rise to the establishment and use of the raised floor in the data center environment are presented.  For many applications the use of the raised floor is no longer justified or desirable. To learn more about this topic, “Is Perimeter Cooling Dead” is available for your organization via our unique “Breakfast and Learn” Educational Series For Data Center Professionals.  This series provides the education that will lay the critical found for your organization to run an efficient data center.  Please feel free to contact me for further information at d.melchert@apcdistributors.com or 918-760-8236.

The Advantages of Row and Rack-Oriented Cooling Architectures for Data Centers (White Paper #30) Overview:

Executive Summary:

Latest generation high density and variable density IT equipment create conditions that traditional data center room cooling was never intended to address, resulting in cooling systems that are inefficient, unpredictable, and low in power density. Row-oriented and rack-oriented cooling architectures have been developed to address these problems. This paper contrasts room, row, and rack architectures and shows why row- oriented cooling will emerge as the preferred solution for most next generation data centers.

Highlights:

  • Discuss the following cooling approaches:  room, row and rack-based cooling architectures.
  • Benefit comparison of cooling architectures:  challenges in agility, availability, lifecycle costs, serviceability, and manageability
  • Special issues:  capacity utilization, humidification, electrical efficiency, water near IT equipment, location and redundancy.
  • Elements of the raised floor and problems associated with using a raised floor.
  • Hurdles to eliminating the raised floor
  • Designing without a raised floor.

Conclusion:

The conventional legacy approach to data center cooling using room-oriented architecture has technical and practical limitations in next generation data centers. The need of next generation data centers to adapt to changing requirements, to reliably support high and variable power density, and to reduce electrical power consumption and other operating costs have directly led to the development of row and rack-oriented cooling architectures. These two architectures are more successful at addressing these needs, particularly at operating densities of 3 kW per rack or greater. The legacy room-oriented approach has served the industry well, and remains an effective and practical alternative for lower density installations and those applications where IT technology changes are minimal.

Row and rack-oriented cooling architecture provides the flexibility, predictability, scalability, reduced electrical power consumption, reduced TCO, and optimum availability that next- generations data centers require. Users should expect that many new product offerings from suppliers will utilize these approaches.

It is expected that many data centers will utilize a mixture of the three cooling architectures. Rack-oriented cooling will find application in situations where extreme densities, high granularity of deployment, or unstructured layout are the key drivers. Room-oriented cooling will remain an effective approach for low density applications and applications where change is infrequent. For most users with newer high density server technologies, row-oriented cooling will provide the best balance of high predictability, high power density, and adaptability, at the best overall TCO.

Avoidable Mistakes that Compromise Cooling Performance in Data Centers and Network Rooms (White Paper#49) Overview:

Executive Summary:

Avoidable mistakes that are routinely made when installing cooling systems and racks in data centers or network rooms compromise availability and increase costs. These unintentional flaws create hot-spots, decrease fault tolerance, decrease efficiency, and reduce cooling capacity. Although facilities operators are often held accountable for cooling problems, many problems are actually caused by improper deployment of IT equipment outside of their control. This paper examines these typical mistakes, explains their principles, quantifies their impacts, and describes simple remedies.

Conclusion:

The air distribution system is a part of the data center that is not well understood, and facility operators and IT personnel often take actions involving airflow that have unintentional and adverse consequences to both availability and cost.

Flawed airflow implementation has not been a serious problem in the past, due to low power density in the data center. However, recent increases in power density are beginning to test the capacity of cooling systems and give rise to hot-spots and unexpected limitations of cooling capacity

Decisions such as facing all racks in the same direction are often made for cosmetic reasons to project image; but as users and customers become more educated they will conclude that people who do not implement airflow correctly are inexperienced, which is the opposite of the original intent.

Adopting a number of simple policies and providing a simple justification for them can achieve alignment between IT and Facilities staff resulting in maximum availability and optimized TCO.

Universal Networking Services Extends Scheduling Deadline For Free Critical Facility Energy Profiles To March 31, 2012.

“Critical Facility Energy Profiles (CFEP) service provides a detailed analysis of the data center power and cooling infrastructure to optimize operating efficiency and significantly control energy costs.”

St. Petersburg, Florida February 22, 2012: Exceptional interest by the data center community for free Critical Facility Energy Profile (CFEP) assessments has prompted Universal Networking Services (UNS), a leading provider of mission- critical power and cooling infrastructure products and services to extend the scheduling date for to March 31, 2012.

Waite Ave, Vice President of Operations, states “Nearly half of a data center’s energy bill is from power and cooling. We are excited to offer this opportunity to the data center community to save on energy costs. Today’s IT departments face complex challenges that demand attention to their bottom line. Up to 75 percent of the energy used feeds power-hungry servers and the operation of mechanical and electrical systems that keep the lights on and, above all, keep the IT equipment cool. Smaller, more powerful IT equipment is considerably hotter than older systems, making heat management a major challenge. UNS and its partners take a broad view of these challenges in today’s IT facilities. Often, our recommendations, without any capital investment by the client, can generate savings on utility costs. If the client choses to implement modern technology such as in-row/in-rack cooling infrastructure the savings are often compounded. As an example, we have seen upwards of 40% savings in our clients utility bill by implementing this sort of IT architecture. Normally pricing is associated with our Critical Facility Energy Profiles but we want to encourage local companies to be proactive in minimizing their costs and maximizing their efficiency by offering this service free for a limited time.  At UNS, we believe education is key to controlling your data center costs.  With that in mind, the CFEP assessment can also be coupled with our Data Center Institute Educational Series.  Our customized training series provides the education that will lay the critical foundation to run an efficient data center.  Based on CFEP findings, UNS can customize a curriculum  specific to your facilities requirements that educate and showcase the latest in technologies and best practices for data center power, cooling, monitoring, security and management.”

Data Center Projects: Standardized Process (#140):

As the design and deployment of data center physical infrastructure moves away from art and move toward science, the benefits of a standardized and predictable process are becoming compelling. Beyond the ordering, delivery, and installation of hardware, any build or upgrade project depends critically upon a well-defined process as insurance against surprises, cost overruns, delays, and frustration. This paper presents an overview of a standardized, step-by-step process methodology that can be adapted and configured to suit individual requirements.

Data Center Projects: System Planning (White Paper #142 and Part 1 of 2 Podcast):

System planning is the Achilles’ heel of a data center physical infrastructure project. Planning mistakes can magnify and propagate through later deployment phases, resulting in delays, cost overruns, wasted time, and ultimately a compromised system. Much of the trouble can be eliminated by viewing system planning as a data flow model, with an orderly sequence of tasks that progressively transform and refine information from initial concept to final design

Data Center Projects: System Planning (White Paper #142 and Part 2 of 2 Podcast):

System planning is the Achilles’ heel of a data center physical infrastructure project. Planning mistakes can magnify and propagate through later deployment phases, resulting in delays, cost overruns, wasted time, and ultimately a compromised system. Much of the trouble can be eliminated by viewing system planning as a data flow model, with an orderly sequence of tasks that progressively transform and refine information from initial concept to final design.

Rack Powering Options for High Density (#29):

Alternatives for providing electrical power to high density racks in Data Centers and Network Rooms are explained and compared. Issues addressed include quantity of feeds, single-phase vs. three-phase, number and location of circuit breakers, overload, selection of plug types, selection of voltage, redundancy, and loss of redundancy. The need for the rack power system to adapt to changing requirements is identified and quantified. Guidelines are defined for rack power systems that can reliably deliver power to high density loads while adapting to changing needs.

The Seven Types of Power Problems (#18):

Many of the mysteries of equipment failure, downtime, software and data corruption, are often the result of a problematic supply of power. There is also a common problem with describing power problems in a standard way. This white paper will describe the most common types of power disturbances, what can cause them, what they can do to your critical equipment, and how to safeguard your equipment, using the IEEE standards for describing power quality problems.

Neutral Wire Facts and Mythology (#21):

This Technical Note discusses many common misunderstandings about the function of the neutral wire and its relation to power problems. The subjects of dedicated lines, phase reversal, isolation transformers, and grounding are addressed. Various myths are described and criticized.

Accounting and Tax Benefits of Modular, Portable Data Center Infrastructure (#115):

Well-informed accounting treatment of Network-Critical Physical Infrastructure (NCPI) assets provides significant opportunities to contribute to improving the financial performance of a business, institution, or organization. Design and manufacturing improvements in modular, scalable UPS systems, power distribution units (PDUs), and computer room air conditioners have not only created technological benefits, but provide entirely new NCPI asset management opportunities with direct and measurable financial benefits.

Understanding EPO and its Downtime Risks (#22):

An Emergency Power Off (EPO) system is intended to power down a single piece of electronic equipment or an entire installation from a single point by activating a push button. EPO is employed in many applications such as industrial processes and information technology (IT). This white paper describes the advantages and disadvantages of EPO for protecting data centers and small IT equipment rooms containing UPS systems. Various codes and standards that require EPO are discussed. Recommended practices are suggested for the use of EPO with UPS systems.

Essential NCPI Service Requirements for Next Generation Data Centers (#12):

Data Centers are a significant investment to the corporations and IT departments who they serve. Whether or not they actually achieve the availability of the design is highly dependent on the quality of the service personnel and their ability to meet the challenges specific to data center management. This paper presents a categorized and prioritized collection of those service challenges and the requirements needed to overcome them. It is based on information obtained in systematic interviews with data center clients and users.

Essential NCPI Management Requirements for Next Generation Data Centers (#14):

The management of physical infrastructure in data centers can no longer be considered independently of the IT management architecture. In order to manage rapid change and achieve demanded levels of availability while controlling Total Cost of Ownership, IT managers can no longer afford to rely on the primitive, customized management solutions of the past. These solutions are no longer effective and must be replaced by systems based on, and integrated with, open IT management standards. With this in mind, this paper describes the requirements for management of next-generation Network-Critical Physical Infrastructure from the perspective of the ITIL framework.

7 Principles of InfraStruXure® HD-Ready Architecture

APC’s award winning InfraStruxure architecture provides an integrated and compatible solution at data centre rack, row and room level. Seven basic principles allow it to be installed into almost any environment, new or old, to provide highly scalable and highly manageable, efficient infrastructure for high density IT equipment.

Seven Principles of InfraStruxure™ Design Video


1. High Density Rack Enclosures
APC’s vendor-neutral NetShelter racks are engineered to accommodate standard sized IT equipment and to ensure that airflow and energy can be provisioned for today’s power hungry devices.

2. Rack and U-level outlet control
Install metered outlet strips to indicate which racks and outlets have available capacity for high density equipment. This provides a ready method for easy decision making regarding server placement in cramped racks.

3. Rack temperature monitoring
Local or remote monitoring of temperature and humidity in equipment racks enables data centre managers to ensure hot spots aren’t emerging as workloads increase.

4. Real-time browser based visibility
Providing real-time, system-wide data on power, cooling and physical security systems at row, rack and U-level through one standard IP address.

5. Software to manage capacity and change
Takes the guesswork out of server placement, basing decision-making on available power and cooling capacity. This effectively eliminates downtime caused by overloaded circuits or exceeded cooling capacity.

6. InRow cooling
As power and heat density per rack increases, hotspots which are a common feature in perimeter cooled environments can be eliminated. This also reduces energy costs as focussed, close coupled cooling eliminates the need to crank up room cooling solutions for the benefit of one or two zones of high density equipment.

7. Flexible, scalable UPS power
As UPS power demand grows, respond quickly and efficiently without wasteful oversizing or upfront capital costs. APC’s range includes scalable in-row, in-room or grey space solutions to meet your requirements.

Hot-Aisle Containment vs. Cold-Aisle Containment….A Lesson In Efficiency

Posted by on February 6, 2012  |  No Comments

Waite Ave, Vice President of Operations

High energy costs and spiking data center energy consumption rates have forced data center professionals to rethink their data center cooling strategies. Although traditional cooling approaches (such as perimeter cooling through a raised floor plenum) are still quite prevalent, new approaches such as hot aisle and cold aisle containment are making significant inroads.

The Cold Aisle Containment System (CACS) is typically deployed in traditional perimeter-based cooling environments. Traditional cooling environments use the entire room as a hot air return plenum and use deliver cold air via the raised floor plenum to the cold aisles. The CACS encloses the cold aisle allowing the rest of the data center to become a large hot air return plenum. By containing the cold aisle, the hot / cold air streams within the data center are separated.

The Hot Aisle Containment System (HACS) encloses a hot aisle to collect IT equipments hot exhaust air and cools it to make it available for IT equipment air intakes. This creates a self-contained system capable of supporting high density IT loads.

Mixing of hot and cold air streams in the data center lowers availability of IT equipment. Returning the warmest possible air to the computer room air conditioners increases the efficiency and capacity of the system. The HACS ensures proper air distribution by completely separating supply and return air paths.

The design of HACS assimilates many of the advantages of the CACS and avoids many of the pitfalls. When upgrading a data center to be more efficient and less costly to operate, any move away from the traditional perimeter cooling approach is a step in the right direction. While CACS is a “better” scenario compared to traditional approach, the “best” scenario is embodied in a HACS system.
