Why Would Companies Buy A Modular Solution?

Posted by on November 29, 2012  |  No Comments

FINANCIAL

CAPEX: Data center design and construction costs can vary widely, according to a large number of criteria. This makes cost comparisons of all kinds of construction difficult, contentious and sometimes misleading. A CAPEX cost of $15m per MW of IT load is a mid-level estimate for a traditional build that would be appropriate for enterprise use. That is the number used in a recent report by 451 Group (The Economics of Prefabricated Modular Data Centers)  for a traditional build, to which prefabricated modular CAPEX costs are compared. The middle 50% of CAPEX cost estimates for prefabricated modular designs are in the range of $8m-11m/MW. The median estimate is around $9m/MW. Prefabricated modular design and delivery of data centers can reduce CAPEX costs by 10-30%.

Deferred Capital Cost: As a large capital expense, building a data center is typically a large project that requires a lot of money upfront to anticipate forecasted IT needs for the next 10 to 15 years. Rapidly changing technology in the data center makes it difficult to justify such a large capital expense for a building that will only hopefully keep pace with technology demands. Modular solutions can be seen as a way to intelligently apply capital to the data center in line with changing technology and IT requirements.

Operating Expense: The engineering in modular solutions has proven, known efficiency throughout subsystems which allow regular operating expenses to be optimized. Optimized power and cooling built-in to modules equate to a lower overall operating expense. The fact that modules are engineered products means that internal subsystems are tightly integrated which results in efficiency gains in power and cooling in the module. First generation and pure IT modules will most likely not have efficiency gains other than those enjoyed from a similar containment solution inside of a traditional data center. Having a modular power plant in close proximity to the IT it serves will save money in costly distribution gear and power loss from being so close. There are opportunities to use energy management platforms within modules as well, with all subsystems being engineered as a whole.

Real Estate: Modules allow operators to build out in increments of power instead of space. Many second generation modular products feature evaporative cooling, taking advantage of outside air. A radical shift in data center design takes away the true brick and mortar of a data center, placing modules in an outdoor park, connected by supporting infrastructure and protected only by a perimeter fence. Some modular solutions offer stacking also — putting twice the capacity in the same footprint.

BUSINESS ALIGNMENT

Rightsizing: Modular design ultimately enables an optimized delivery approach for matching IT needs. This ability to right-size infrastructure as IT needs grow enables enterprise alignment with IT and data center strategies. The module container can also provide capacity when needed quickly for projects or temporary capacity adjustments.

Supply Chain: Many of the attributes of a modular approach speak to the implementation of a supply chain process at the data center level. As a means of optimizing deployment, the IT manager directs vendors and controls costs throughout the supply chain.

Total Cost of Ownership:

  • Acquisition: Underutilized infrastructure due to over-building is eliminated by being deployed as needed.
  • Installation: Weeks and months instead of more than 12 months.
  • Operations: Standardized components to support and modules are engineered for extreme-efficiency.
  • Maintenance: Standardized components enable universal maintenance programs.

 

OPERATIONAL

Speed of Deployment: Modular solutions have incredibly quick timeframes from order to deployment. As a standardized solution it is manufactured and able to be ordered, customized and delivered to the data center site in a matter of months (or less). Having a module manufactured also means that the site construction can progress in parallel, instead of a linear, dependent transition.

Standardization: Seen as a part of the industrialization of data centers the modular solution is a standardized approach to build a data center, much like Henry Ford took towards building cars. Manufactured data center modules are constructed against a set model of components at a different location instead of the data center site. Standardized infrastructure within the modules enable standard operating procedures to be used universally. Since the module is prefabricated, the operational procedures are identical and can be packaged together with the modular solution to provide standardized documentation for subsystems within the module.

Scalability: With a repeatable, standardized design, it is easy to match demand and scale infrastructure quickly. The only limitations on scale for a modular data center are the supporting infrastructure at the data center site and available land. Another characteristic of scalability is the flexibility it grants by having modules that can be easily replaced when obsolete or if updated technology is needed.

Mobility and Placement: A modular data center can be delivered where ever its desired by the end user. A modular solution is mobile in the sense that it can be transported in pieces and reassembled quickly on-site. Mobility is an attractive feature for those looking at modular for disaster recovery solutions.

Density and PUE: Density in a traditional data center is typically 100 watts per square foot. In a modular solution the space is used very efficiently and features densities as much as 20 kilowatts per cabinet. Because the module is pre-engineered and standardized densities are higher and the effective use of electrical power is improved.  (The Economics of Prefabricated Modular Datacenters; 451 Group, 2012).

  • RECYCLED/RECYCLABLE MATERIALS: The Datapod System uses recycled steel in its outer shell construction and other recycled or recyclable materials where ever possible throughout design and build.

BRINGING IT ALL TOGETHER (FACTS AND FIGURES):

PROJECTPOD: Enable onsite computing and storage where and when you need it. Standalone fully self-contained, transportable for rapid deployment.  Includes fully self-contained air-cooled DX versions, provides data center capability anywhere at short lead time and for as long as required.  Low, medium, and high-density versions, utilizes condenser water or chilled water.

STARTERPOD: The starting point and first pod of your Datapod system, it contains the power, cooling and data input connections. Incorporates InRow Cooling and IT Enclosures, the expandable APC modular Symmetra UPS gives you the starting point for growth as required.  Built-In InRow cooling and NetShelter enclosures ensure your data center is up and running with no further upfront investment.  When 2 Starterpods are used, a 2(N+1) system is created providing the highest levels of availability and redundancy.

EXPANDERPOD: Grow your Datapod system by adding the pre-built Expanderpod.  It easily connects onto other ‘pods’ to expand your system.  Removable side-walls allow the creation of a limitless best-of-breed computer room, the system can be expanded as required by your IT needs, aligning your budgets with your requirements in real-time.  With pre-deployed power, inrow cooling and enclosures, you can build your data center on-demand.

ENDPOD: End your Datapod system with the Endpod.  The data center Hot Aisle can be accessed from either end.  The Endpod add more power, cooling and IT enclosures, and gives users the necessary space, access and the end door to the APC Hot-Aisle Containment System.  The Endpod is optional-some Datapod systems will continue to grow over time and not deploy the Endpod.  The solid, non-removable end wall ensures the highest levels of resistance to the elements.

CONNECTION NODE: The Connection Node makes the setup of the Datapod system a breeze.  This pre-deployable skid-mounted utility connection system for mains and generator power, cooling and data is designed to simplify the deployment, modification and removal of the Datapod System. Delivered to site in advance of the Starterpod, the Connection Node connects to the site mains power supply and optional diesel generator backup power supply. Data communication links and chilled water or condenser water from the site supply or Utilitypod are connected via the Connection Node.  Positioned 1 to 2 meters from the designated location, our APC engineers simply connect these 3 utilities from the Connection Node to the Datapod using pre-assembled link systems for rapid deployment.

ENTRYPOD: The Entrypod creates a secure and weatherproof system that doubles as office or storage space for data center staff.  The 10′ Entrypod cubicle, fitted with proximity card magnetic lock systems keeps the elements out of your data center.  It connects on both ends and enables multiple Datapods to be connected together via the Entrypod.

UTILITYPOD: The Utilitypod provides the backup power and cooling for your Datapod to operate anytime, anyplace.  Easily transportable, fully-rated diesel generator and fuel tans for backup power supply, and multiple redundant chillers to support the highest density Datapod system.  Housed within an identical 20′ enclosure and the capacity to support the highest density Datapod systems, the diesel generator provides 280kW of useable output power.  Cooling is supplied by 3X80kW chillers, giving redundancy to the critical cooling system.  The Utilitypod can be pre-deployed with the Connection Node or added later, as required. Alternatively the Utilitypod is available as a standalone system for use in non-Datapod projects.

Battery Technology for Data Centers and Network Rooms: Ventilation

Posted by on July 9, 2012  |  1 Comment

White Paper 34

The main objectives of any ventilation system are management of environmental air temperature, humidity and air quality. In a data center, or any facility in which electrical equipment and battery systems are installed, the ventilation system must address:

  • Health safety – the air must be free of pollutants that could be toxic, corrosive,poisonous, or carcinogenic
  • Fire safety – the system must prevent and safely remove the accumulation of gasses or aerosols that could be flammable or explosive.
  • Equipment reliability and safety – the system must provide an environment that optimizes the performance of equipment (including both batteries and electronic equipment) and maximizes their life expectancy
  • Human comfort

“Battery Technology for Data Centers and Network Rooms: Ventilation” Full White Paper (Click Here To Download)

Stationary lead-acid batteries are the most widely used method of energy reserve for information technology rooms (data centers, network rooms). Selecting and sizing ventilation for battery systems must balance and trade off many variables. These could include different battery technologies, installation methods, operating modes, and failure modes.

Executive Summary:

Lead-acid batteries are the most widely used method of energy reserve. Ventilation systems must address health and safety as well as performance of the battery and other equipment in a room. Valve regulated lead acid (VRLA) batteries and modular battery cartridges (MBC) do not require special battery rooms and are suitable for use in an office environment. Air changes designed for human occupancy normally exceed the requirements for VRLA and MBC ventilation. Vented (flooded) batteries, which release hydrogen gas continuously, require a dedicated battery room with ventilation separate from the rest of the building. This paper summarizes some of the factors and codes to consider when selecting and sizing a ventilation system for a facility in which stationary batteries are installed.

Contents:

  • Terminology
  • Environmental design considerations

Conclusion:

Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability/ safety, and human comfort. Vented (flooded) batteries should be installed in dedicated battery rooms, but may share the same room as the equipment they support (such as a UPS system). VRLA batteries and modular battery cartridges can be used in an office environment. The amount of heat generated by a battery system is insignificant compared to the total IT system. However, batteries need cool, clean air for optimum performance and long life. Vented batteries must have a dedicated ventilation system that exhausts to the outside and prevents circulation of air in other parts of the building. For VRLA and MBC systems, the ventilation required for human occupancy is normally sufficient to remove heat and gases that might be generated. A minimum of two room air changes per hour and a temperature in the range of 20 – 24° C (68 – 75° F) are recommended. The ventilation system must prevent the accumulation of hydrogen pockets in greater than 1 – 2% concentration.

For vented batteries, it is recommended to enlist the services of an engineering firm experienced in battery room design, including ventilation, fire protection, hazardous material reporting and disposal, and spill control.

For VLRA and MBC battery systems, the ventilation requirements for human occupancy and electronic equipment operation in a data center or network room well exceed the requirements for the batteries. No additional engineering should be necessary for VRLA battery ventilation.

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.

About UNS “Breakfast and Learn Series for Data Center Professionals”:

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.

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

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.

Watts and Volt-Amps: Powerful Confusion (#15):
