Data centers often have multiple fiber connections to the internet provided by multiple … Can the facilities team decide on the power supplies to be ordered when new IT equipment is purchased. However, legacy equipment or specialized IT equipment may have very precise voltage requirements, thereby not allowing for operation at the higher 240 V level. If cooling is implemented poorly, the power required to cool a data center can match or exceed the power used to run the IT equipment itself. The premise behind a 3M2 system is that there are three independent paths for power to flow, each path designed to run at approximately 66.7% of its rated capacity and at 100% during a failure or maintenance event. In today’s business climate, power outages as well as data downtime is not an option, particularly as data centers evolve in line with the proliferation of connected devices and wider digital transformation. – Despite the availability of consolidation technologies, organizations Info-Tech surveyed were two times more likely to increase the size of their data center than decrease it. This estimate assumes a traditional c-Si PV array (without trackers). A great resource for PV and renewable energy in general is the National Renewable Energy Laboratory. On the other hand, in most cases, liquid-filled transformers can be repaired or rewound. This technical bulletin highlights the environmental and reliability challenges of edge data centers and the design and maintenance challenges of these data centers that are surrounded by semi-controlled or even uncontrolled external environments. The follow-on question typically asked is if the entire data center can run at 415 V, rather than bringing in 480 V and having the energy loss associated with the transformation to 415 V. While technically feasible, the equipment costs are high because standard HVAC motors operate at 480 V. Use of 415 V for HVAC would require specially wound motors, thus increasing the cost of the HVAC equipment. There are four ratings defined by ISO-8528: The generator industry also has two additional ratings that are not defined by ISO-8528: mission critical standby and standby. Data Centre Design – basic considerations by Future-tech | May 10, 2012 | Articles , Design | 0 comments The key areas to consider when designing a data centre are airflow and cooling, humidification, power supply, and cabling pathways. The liquid-filled transformer must be physically separated from doors, windows, and similar building openings in accordance with NEC Article 450.27. Within each category, there are several different types. Why Implement a Data Center Core Layer? Connectivity. Data Center Design Construction Considerations serves as a basic introduction to current and next level of engineering design for data centers, so anyone can successfully build a data center… This reconfiguration would allow the system to provide full reserve capacity even while a system is being maintained. Is your data center design and build partner highly engaged? The information within the data center can be leveraged by many other groups and systems within an organization. Debra Vieira is a senior electrical engineer at CH2M, Portland, Ore., with more than 20 years of experience for industrial, municipal, commercial, educational, and military clients globally. Design strategy can have an enormous impact on your business. There isn’t a single “best” system topology. While still in design, some considerations include moving to in-row air distribution, leaving the underfloor for only piping and electrical (data overhead). Crystalline silicon (c-Si) is the most common PV array type, along with thin-film and concentrating PV. The utility infrastructure is built to support an increase of load up to 10 MW. If the generator is capable of a higher performance, then the manufacturer can determine the listed rating. Thin-film is generally less efficient than c-Si, but also less expensive. The program also addresses the importance of accurate interpretation of detailed customer requirements at the planning stage to ensure that the business needs remain focal to all decision making. ... We spend a lot of time focusing on airflow, power sources, building design, and servers. That’s more than twice the power from the same circuit for no extra distribution cost. Available Languages. Recommended annual maintenance for a cast coil transformer consists of inspection, infrared examination of bolted connections, and vacuuming of grills and coils to maintain adequate cooling. The principle benefit of using Article 645.10 is to allow more flexible wiring methods in the plenum spaces and raised floors. Vacuum-pressure encapsulated (VPE) transformer windings are encapsulated with silicon resin typically applied in accordance with a military spec and used in locations exposed to salt spray, such as shipboard applications with the U.S. Navy. Corporations and data center investors are demanding sustainability be built into the data center. March 23, 2020 | In Uncategorized | By Kris Puccio. This article delves into some key issues worth paying attention to. Design Zone – Data Center. This course prepares the student with the skills to lead the design of NSX-T Data Center offered in the NSX-T Data Center 3.0 release, including design principles, processes, and frameworks. However, advances in insulating fluids, such as Envirotemp FR3 by Cargill, a natural ester derived from renewable vegetable oil, is reducing the advantages of dry-type transformers. Understand the different transformer types. This option of outdoor installation has the additional advantage of reducing data center cooling requirements. Data center designs assume a constant load and worst-case ambient temperatures. Power consumption in the data centers have grown drastically in the recent years. A tier 1 data center can be little more than a powered warehouse. With the push of a button, the entire data center power and cooling can be shut down. The premise behind a 2N system is that there are two occurrences of each piece of critical electrical equipment to allow the failure or maintenance of any one piece without impacting the overall operation of the data center IT equipment. Can we use photovoltaic systems to power our data center? Because cast coil transformers are air-cooled, they are often larger than their liquid counterparts assuming the same voltage and capacity (kVA rating). To keep up with these changes and ensure that space, power, cooling and networking is always available you need to have robust analytics and reporting to keep staff and management abreast of current and future capacity needs. However, if an end user truly desires an unlimited number of run hours, then a standby-rated generator is not the appropriate choice. When planning a data center design, most of the effort is going to be focused on the actual areas where the servers and other equipment are kept. The need for an EPO is typically triggered by NEC Article 645.10, which allows alternative and significantly relaxed wiring methods in comparison with the requirements of Chapter 3 and Articles 708, 725, and 770. Taking all the above into consideration, it becomes clear that spreadsheets and other manual approaches cannot keep up with the changes occurring in a modern data center. A good data center design should plan to automate as many of the operational functions that employees perform as possible. These relaxed wiring methods are allowed in exchange for adding an EPO system and ensuring separation of the IT equipment’s HVAC occupancies from other occupancies. 2N topology. These various ratings can make selecting the correct generator type complicated. The inverter will reconnect when utility power is available. A good data center design should plan to automate as many of the operational functions that employees perform as possible. VPE transformers are superior to VPI transformers, with better dielectric, mechanical, and short-circuit strength. A full containment installation will, in many cases, create physical zones which are isolated from existing fire detection systems such as smoke detectors and VESDA inlets. However, this does not include the space required for access or other ground-mounted appurtenances. Beyond the basic factors related to physical and logistical … Now, if that same 20-amp circuit was operating at 415 Y/240 V, 3-phase, then that circuit could power a cabinet up to 11.5 kVA (20 amps x 0.8 x √3 x 415 V). While not required, medium-voltage UPS topologies are typically used for full-facility protection rather than using independent information technology and mechanical-cooling UPS systems, further reducing the building footprint. Data Centre Dynamics Ltd (DCD)& DC Professional Development Limited (DCPRO)22 York Buildings,John Adam Street,London WC2N 6JUEmail. These systems are typically small (less than 500 kW) and can be located on building rooftops, carports, and on the ground. The dry-type category can be subdivided into five categories with the following features: For liquid-filled transformers, various types of fluids can be used to insulate and cool the transformers. Additionally, omitting the oil sampling does not decrease the transformer efficiency. Typically, PV arrays are rated at 77˚F, allowing them to perform better in cold rather than in hot climates. However, there are a few companies who are building recyclable cast coil transformers. However, if less-flammable liquid-insulated transformers are installed indoors, they are permitted in an area that is protected by an automatic fire-extinguishing system and has a liquid-confinement area in accordance with NEC Article 450.23. An often-questioned item is whether photovoltaic (PV) systems can be used to meet some of the sustainability requirements in a data center environment. This configuration has a number of impacts to the distribution: N+1 shared redundant (N+1 SR). The shared module in this topology has the same equipment capacities and configuration as the primary power system, minimizing the types of equipment to maintain. DATASHEET | 1 COURSE DAT ASHEET VMware NSX-T Data Center: Design Course Overview This five-day course provides comprehensive training on considerations and practices to design a VMware NSX-T™ Data Center environment as part of a software-defined data center strategy. The total land required is better estimated at about 4 acres per MW. Typical cast coil transformers operate in the 64 to 70 dB range while liquid-filled transformers operate in the 58 to 63 dB range. From the moment a business designs its data center it is constantly being redesigned. Uptime Institute has created the "Top Ten Considerations for Data Center Design & Engineering RFPs" guide to help world-class data center architects, design engineers, operations directors and end-users understand and employ best practices in writing, bidding on, and evaluating Data Center Design & Engineering RFPs and RFP responses. These include less-flammable fluids, nonflammable fluids, mineral oil, and Askarel. Edge Computing: Considerations for Reliable Operation. Chilled efficiency: Building Boden's Type Data Center One. The steel, copper, and aluminum can be recycled. Most data centers do not have the necessary land to install a PV system, which substantially offsets the power demand. The location of the servers and other key equipment The NREL website provides information on PV research, applications, publications as well as a free online tool, PVWatts, which estimates the energy production and cost of energy of grid-tied PV systems throughout the world. However, if the demand for high electrical and mechanical performance is of the utmost concern, then cast coil would be the appropriate choice. This path also has an N+1 capacity UPS to facilitate maintenance and function in the event of a UPS failure. Additionally, many utility companies will offer incentives for the use of energy-efficient and sustainable technologies. There are two categories of distribution transformers: dry-type and liquid-filled. Tim Miscovich shares insights on the impact of data center lighting and how your lighting plays a key role in your green data center strategy. The positive impact on public relations by showcasing a sustainable data center can’t be underestimated, especially considering how much of a power hog data centers can be. When a cast-coil transformer fails, the entire winding is rendered useless because it is encapsulated in epoxy resin. Cast coil transformers have more core material, which implies higher costs and losses. A simple rule is to assume 100,000 sq ft (about 2.5 acres) for a 1-MW PV-generating plant. Learning objectives: Updated: May 14, 2008. However, similar systems can be developed using a medium-voltage UPS. Design topology evaluation also should consider the medium-voltage uninterruptible power supply (UPS). No matter the system topology, the requirement to transfer load between electrical systems—either for planned maintenance activities, expansions, or failure modes—must be done. In most cases, this is going to be an office area just outside the data center itself. Concentrating PV arrays require direct sunlight and tracking systems to be most effective and are typically used by utility companies. The right Data Centre Design for your business. In the infrared region of light, solar cells are too weak to create electricity; and in the ultraviolet region of light, solar cells create heat instead of electricity. They are not required to be very sophisticated. A standby-rated generator can provide the nameplate rating for the duration of an outage assuming a load factor of 70% and a maximum run time of 500 hours/year. Data Center Design Considerations. Generally, data center sustainability is addressed more directly through efficient cooling and electrical distribution systems. A medium-voltage alternative to low-voltage UPS. Typically, interactive inverters include batteries to carry the system through power outages, therefore the system should be designed such that there is enough PV-array capacity to supply the load and charge the batteries. This system not only provides data center visualization, robust reporting and analytics, but also becomes the central source-of-truth for changes being made in the data center. Traditionally less-flammable liquid-filled transformers are installed outdoors. The following are the most common questions that this CH2M office has received along with a concise overview. (Image: Intel) So for engineers engaged in AI-centric data center and cloud computing environments, what are the basic design considerations relating to hardware accelerators? There are other topologies and multiple variations on these topologies. Emergency power-off (EPO) buttons are the fear of every data center operator. Based on research performed by Caterpillar, real-world data center applications show an inherent variability in loads. Because of the devastation that activation of an EPO can cause, EPOs typically are designed with a two- or three-step activation process, such as lifting a cover and pressing the button or having two EPO buttons that must be activated simultaneously. The premise behind the N+1 SR system is that each IT block is supported by one primary path. Where improved functionality is necessary for building a great data center, adaptability and flexibility are what contribute to increasing the working efficiency and productive capability of a data center. The design should incorporate the existing needs, scalability, adopting future technologies and budget demands. Each topology has pros and cons that must be weighed against the performance, budget, schedule, and the ultimate function of each data center. Designing a Data Center 17 Design Process 17 Design Drawings 19 Designing for Data Center Capacities 20 Data Center Structural Layout 21 Structural Considerations 22 Raised Floor 23 Aisles and Other Necessary Open Space 23 Command Center 24 Data Center Support Systems 25 Space and Weight 26 Power Requirements 26 HVAC and Air Flow Requirements 26 Liquid-filled transformers are more efficient than cast coil. A decibel is a logarithmic function and sound pressure doubles for every 3-dB increase. Data centers are growing at a rapid pace, not in size but also design complexity. How much power needs to be delivered to each IT cabinet initially, and what does the power-growth curve look like for the future? Factors that Influence Scalability. Data centers are among both the most complex and energy-demanding building environments of the modern age. They generally are installed outdoors in containers, thereby minimizing the conditioned building footprint. This five-day course provides comprehensive training on considerations and practices to design a VMware NSX-T™ Data Center environment as part of a software-defined data center strategy. Because air is the basic cooling and insulating system for cast coil transformers, they will be larger than liquid-filled units of the same voltage and capacity. To help select the appropriate generator, manufacturers have developed ratings for engine-generators to meet load and run time requirements under different conditions. However, the choice of distribution voltage between 208 Y/120 V or 415 Y/240 V depends on the answers to several questions, such as: Let’s start with the power of a 3-phase circuit. Whether small or hyperscale, a cloud service provider or a business looking to keep data on-prem, good design is important to creating and maintaining a highly efficient data center. However, EPOs are not necessarily required. Maintenance for a liquid-filled transformer consists of drawing and analyzing an oil sample. Liquid-filled transformers have the distinct disadvantage of requiring fluid containment. The physical space required to install the PV array can be significant. Deploy applications, analytics, virtualization, and converged infrastructure faster using proven solutions. There isn’t a ranking system for topologies; one isn’t better than another. Data Center facilities require industrial design and engineering – Data centers are getting bigger and more complex. Added to this are the inefficiencies of the inverter, and if used, storage batteries. For example, building management systems (BMS), IT systems management (ITSM), and with virtualization management solutions like VMware and Nutanix. DATA CENTER Space. In order to address this issue an organization should control airflow and cooling via containment and active airflow management that provides modular power and cooling which scales with demand/expansion. Looking for technical training? The buildup of material on the transformer grills and coils can lead to decreased transformer efficiency due to decreased airflow. However, both types can be installed outdoors. set of efficient baseline design approaches for data center systems and design suggestions that provide efficiency benefits in a wide variety of design models. When operating at the same current, more material and more core and coil imply higher losses for cast coil. Data design strategy can have an enormous impact, which in turn can lead to cost savings, greater ability to scale and reduced environmental impact. size - one room of a building, one or more floors, or an entire building, and can hold 1,000 or more servers; space, power, cooling, and costs in the data center. Although in most data centers, the critical load dwarfs the noncritical load; therefore it’s rare that a PV system would generate power on the grid. Increase this area by 30%, for a total of about 6 acres, if thin-film technology (without trackers) is used due to the inefficiencies of the technology. Per NEC Article 210.20, branch-circuit breakers can be used up to 80% of their rating, assuming it’s not a 100%-rated device. Here are some key Data Center Design Considerations. Most times, cleaning of the grills and coils requires the transformer to be de-energized, which often leads to this maintenance procedure being skipped. These multistep options assume that the authority having jurisdiction has provided approval for such a design. Liquid-filled transformers seem less susceptible to this problem, as there is no published data on their failure. Thus, in designing your data center and systems you should always keep in mind and plan accordingly in order to integrate solutions that can be integrated with technology in other areas of business. Table Of Contents. There is only the best topology for an individual data center end user. Get a call from Sales. Thank you! Data Center Design Considerations. Generators need to be able to deliver backup power for an unknown number of hours when utility power is unavailable. Cast coil transformers typically are not repairable; they must be replaced. You will receive a confirmation email shortly. In this way, the business avoids running out of resources when someone in the business needs them most. Automation should occur at multiple stages, from on-going discovery and audit, to workflow, and cross system integration. The data center National Institutes of Health Sustainable Data Center Design Guide … Because the grid-tied inverter connection is downstream from the utility revenue meter, a billing mechanism known as net metering generally is used. A commonality between the different topologies presented is the need to transfer load between systems. DCIM solutions have become ubiquitous in the data center and hybrid compute infrastructure, and deemed necessary with the complex rapidly changing technology footprint. Over the past several years, mission critical clients seem to be asking the same series of questions regarding data center designs. Smoke inside the containment zone will not reach the detectors in their current location.
