Best Practices for Data Center Facilities Design, Efficiency and Operations

Boost Your Data Center Efficiency with Multi-mode UPS Systems

2017-12-05T13:39:12.939+08:00

When consulting-specifying engineers look at the hundreds of technology factors that go into a data center’s design, they know that even small variables, when multiplied by big numbers, add up quickly. That’s the case with seemingly small incremental increases in energy efficiency for uninterruptible power supply (UPS) systems used in data centers around the world. According to the Uptime Institute, traditional transformer-based UPS devices represent only 12% of a typical data center’s energy consumption, given power use and energy conversion inefficiencies and heat loss. Although they account for only a fraction of the total energy consumption in a data center, even small improvements in UPS energy conversion efficiency can add up to significant lifecycle operational cost savings.Figure 1: Typical Data Center AC-Power ConfigurationTraditional double conversion UPS units (Figure 1), which protect the load during outages — use a rectifier to convert the alternating current (ac) power to direct current (dc) power, and an inverter to provide safe and clean ac power to the load using either the main or battery power. Unfortunately, in this scenario power efficiency is the price paid for protection. Transformer-based double conversion UPS systems have a typical power efficiency rating in the range of 88% to 92%. As a result, double conversion UPS systems place a steep toll on annual data center energy operating budgets. Newer three-level insulated gate bipolar transistor (IGBT) UPS technologies, which reduce switching and filtering power conversion losses, offer efficiency levels approaching 97% in double conversion mode, and up to 99% efficiency when operating in energy-saving multi-mode. These new, three-level UPS topologies create new OpEx rationales when designing data center power systems and specifying UPS technologies. Multi-mode Transfer Speed So what’s that optimum switching or transfer time? According to a Green Grid white paper on multi-mode (or eco-mode), “if, for example, a UPS has a transfer time of greater than 10 ms and is paired with information technology (IT) equipment that has ride-through capabilities of only 10 ms, the UPS may not be able to support the IT equipment.” That’s one of the reasons a few companies design their multi-mode UPS products with transfer speeds of less than 2 ms. The technologies that help achieve these speeds are seamless and represent a robust set of power disturbance detection, analysis, and control systems. When a multi-mode UPS unit’s responsive monitoring technologies detect any sort of deviation on the main or bypass power path, the inverter is immediately turned on to allow quality power to flow from the double conversion premium protection mode. In the same instant, the static switch on the bypass path from the utility is turned off to block the disturbance from reaching the load.A variety of disturbance analyzers and fast-switching technologies are employed in combination, includingAn instantaneous adaptive voltage error detector that monitors subtle changes in amplitude and durationA root mean square (RMS) voltage error detector that computes the RMS of all three UPS output voltages for variancesAn output short circuit detector that, after a breaker is tripped, will automatically increase line current to rapidly clear and reset the breakerA sophisticated transient inverter controller that quickly manages the transfer of the load to inverter power and back again to the bypass path.All of these advanced monitoring and control systems work in concert to anticipate and respond to a comprehensive set of possible power conditions, creating a transfer switch speed of less than 2 ms. This speed helps to maximize the intermittent transfer to double conversion protection, while maintaining higher multi-mode efficiency for the majority of the time when quality utility power is flowing. Lifecycle CostsIn evaluating efficiency and lifecycle costs for multi-mode UPS systems, some might ask: If our UPS running in double conversion already gets us to 93% efficiency, why[...]



Data Center Design Consideration: Meet Me Rooms (MMR)

2017-10-25T17:10:05.683+08:00

A co-location facility / carrier-neutral data center hosts services from multiple carriers (telecommunication companies) or organizations. Meet-me rooms (MMR) are important physical spaces (2 or more for redundancy) located in the building of a co-location data center or carrier-neutral data center. Data center clients use this space to interconnect or cross-connect to a single or multiple carriers (for redundancy) and to exchange information, which can be transmitted to individual computers via the Internet, without incurring local-loop fees.Although the concept and practice of using an MMR are not new, the initial creation and management of these spaces over time has become a serious challenge for operators. Owing to some poor practices and lack of building standards, there have been occasions where new clients' preferred carrier could not be accommodated as a result of physical / location challenges. We are going to outline some design best practices.CABINETS AND SPACEA carrier generally asks for at least 2 four-post, 84" (45U) high cabinets in each MMR. If the operator is providing only AC power, the carrier may request additional rack space for rectifiers and batteries, should they be using DC equipment.The best practice is to meet with the intended carriers all at once to create a rack and space solution that they can all agree on. Although this may be a difficult task to schedule, it will be worthwhile to reach an agreement on one typical rack type and one layout look and feel.Clients who inspect your facilities before signing a contract will appreciate a consistent look to this space. Permitting odd-size cabinets combined with open-frame racks of all colors and widths will detract from a professional look and limit the usefulness of space for new or different functions.Meet-Me Rooms tend to be smaller because fibers would be run from a user suite to patch panels in an MMR to be interconnected, which requires little space. With time, these rooms have grown in size and are starting to resemble data centers, including features such as cages.LOCATIONThe location of the MMRs would be outside the computer rooms, in the secure data center space. When determining location for one or redundant rooms, consider the industry standards for distance, which will vary according to service type and media (fiber/copper/coax). Placing the MMR on an outside wall is ideal if the space will double as the point of entry so that equipment and workers can go in and out using external doors without disrupting data hall's operations.Depending on the expected user population, locating the MMR on an exterior wall and even near a loading dock could be a deal breaker for security reasons. If your clients require significantly more security than normal commercial businesses, the MMR should not act a main point of entry but should instead be placed within the data center, away from external walls.CONNECTIONSThe connection to the data center clients and carriers / MMRs have many methods. Some standards exist. Each method has challenges in co-location facilities, and each challenge can be met so long as they are identified early and planned for.Direct Connect —Each carrier connects directly with the client from the carrier-equipment rack to the client-side demarcation point or equipment rack which is also located in a secure half of the MMR (see figure below). The client then extends to the floor space.The MMR is split for security reasons between clients and carriers. Clients are permitted in their side of the MMR, and carriers in theirs. This approach could increase the amount of conduit in the ceiling space and limit future installations. Using a private cage for client-side equipment or third-party cross-connect provider as the only staff permitted in the client side of the MMR could limit a security concern.Direct Connect (Extended Demarcation Point) —It means each carrier connects directly with the client from the carrier-equipment rack in the MMR to the client-side demarcation point located in the client spac[...]

Data Center Design: Codes and Standards

2017-10-25T16:58:30.130+08:00

Data center is a dedicated space where it houses the most important information and it being safe and accessible. Best practices ensure that you are doing everything possible to keep it that way.Best practices mean different things to different people and organizations. We are going to focus on the major best practices - codes, design standards, and operational standards -  applicable across all types of data centers, including enterprise, colocation, and internet facilities. We will explore the best practices with respect to facility conceptual design, space planning, building construction, and physical security, as well as mechanical, electrical, plumbing, and fire protection. Facility operations, maintenance, and procedures will be the final topics for the series.Following suitable codes and standards would seem to be an obvious direction when designing new or upgrading an existing data center. Data center design and infrastructure standards can range from national codes, like the NFPA (National Fire Protection Association), to local codes, like the New York State Energy Conservation Construction Code, and performance standards, like the Uptime Institute’s Tier Standard. Green certifications, such as LEED and Energy Star are also considered but optional.Codes must be followed when designing, building, and operating your data center, but “code” is the minimum performance requirement to ensure life safety and energy efficiency in most cases. A data center is probably the most expensive facility your company ever builds or operates. Should it have the minimum requirement by code? It is clear from past history that minimum code requirement is not the best practice. Minimum requirement for fire suppression would involve having wet pipe sprinklers in your data center. However, it is definitely not a best practice for your critical facilities.Major Data Center StandardsThe major data center design and infrastructure standards developed for the industry include :-Uptime Institute’s Tier Standard This standard develops a performance-based methodology for the data center during the design, construction, and commissioning phases to determine the resiliency of the facility with respect to four Tiers or levels of redundancy/reliability. The Tiers are compared in our previous post below and can be also found in greater definition in the "Tier Classifications Define Site Infrastructure Performance". The origins of the Uptime Institute (UI) as a data center users group established it as the first group to measure and compare a data center’s reliability. It is a for-profit entity that will certify a facility to its standard, for which the standard is often criticized.(1) Data Center Tier Levels and Uptime(2) More about Data Center Tier LevelsANSI/BICSI 002-2014Data Center Design and Implementation Best Practices by BICSI - The standard covers the major aspects of planning, design, construction, and commissioning of the MEP (Mechanical, electrical, and plumbing) building trades, as well as fire protection, IT installation and maintenance. It is arranged as a guide for data center design, construction, and operation. Ratings / Reliability is defined by Class 0 to 4 and certified by BICSI-trained and certified professionals.TIA Standard Telecommunication Industry Association (TIA) for Data Center Infrastructure Design Standards: This standard is more IT cable and network oriented and has various infrastructure redundancy and reliability concepts based on the Uptime Institute’s Tier Standard. In 2013, Uptime Institute requested that TIA stop using the Tier system to describe reliability levels, and TIA switched to using the word “Rated” instead of “Tiers”, defined as Rated 1-4. TIA uses tables within the standard to easily identify the ratings for telecommunications, architectural, electrical, and mechanical systems.TIA has a certification system in place with dedicated vendors that can be retained to provide facility cert[...]

InRack and InRow Cooling for Data Center

2017-10-25T16:53:23.045+08:00

Traditional data center, computer room, and server room cooling methods cool down an entire room with cold air from centralized units to one end of the room. This approach is acceptable when power densities are minimal with few hot spots in the room. However, room-oriented designs are affected by room constraints including ceiling height, room shape, obstructions above and below the floor, rack layout, Computer room air conditioning (CRAC) units' location, power distribution, etc.CRAC units force chilled air into a data center and around the equipment. In most cases, cooling these vast volumes of air is very inefficient. Although a hot and cold aisle containment decreases the volume, it still results in a lot of excess cooling and costs of powering the CRACs. So why don't consider more selective data center cooling options which work together with your CRAC units or chill specific critical loads with high efficient ways but low energy cost?Modern data centers adopt InRack and InRow coolers (IRCs), also known as close-coupled cooling systems, because they are tailor-made for high densities of hot-running IT equipment and tight energy budgets. These cooling strategies are inherently more efficient than standard CRAC systems because it ties into the IT equipment rather than sending cooled air into the room space. They may be mounted among the IT racks / cabinets or they may be mounted overhead or under the floor.InRack CoolingDedicated racks, another low-effort retrofit, offer cooling isolation. The rack operates just like a standard data center rack, but it is sealed on all sides as a self-contained system. Cool air is forced up through the rack from the bottom, running over the equipment before exiting through the top to a hot plenum, where the heat is vented or recovered as necessary. allowfullscreen="" class="YOUTUBE-iframe-video" data-thumbnail-src="https://i.ytimg.com/vi/puuGJ4mb1Wg/0.jpg" frameborder="0" height="266" src="https://www.youtube.com/embed/puuGJ4mb1Wg?feature=player_embedded" width="320">InRow CoolingIn-row cooling systems work within a row of standard server racks. The units are standard rack height, making them easy to match with the row and couple tightly to the IT equipment to ensure efficient cooling. Systems from APC by Schneider Electric, Liebert by Emerson Network Power, Rittal and others are engineered to take up the smallest footprint and offer high-density cooling. Ducting and baffles ensure that the cooling air gets where it needs to go.     allowfullscreen="" class="YOUTUBE-iframe-video" data-thumbnail-src="https://i.ytimg.com/vi/ELUaPmCP6KM/0.jpg" frameborder="0" height="266" src="https://www.youtube.com/embed/ELUaPmCP6KM?feature=player_embedded" width="320">Compared with the room-oriented architecture, the airflow paths are shorter and more clearly defined with the close-coupled cooling systems. Smaller fans can be used due to lower volumes of chilled air; energy costs are minimized; it is easier to target air onto high-density hot spots for preferential cooling; and business continuity improves, as the failure of any one single unit in the cooling environment only affects that rack or cabinet, as opposed to the total data center or the whole aisle containment. And, as the majority of these systems are modular, it is easy and cost-effective to build in degrees of resilience, leading to higher availability across the whole data center.About usStrategic Media Asia (SMA) is one of the approved CPD course providers of the Chartered Institution of Building Services Engineers (CIBSE) UK. The team exists to provide an interactive environment and opportunities for members of ICT industry and facilities' engineers to exchange professional views and experience.SMA connects IT, Facilities and Design.

Data Center Design Consideration: Transformers and Harmonic Distortion

2017-10-25T16:57:18.988+08:00

Data center managers and information technology (IT) engineers in today's critical facilities are in search of reliable and energy-efficient equipment with low total cost of ownership. But after equipment investments are made, it's important to pay attention to possible threats to the operational efficiency.One threat that is often overlooked is harmonic currents, which can have a significant impact on electrical distribution systems and the facilities they feed. Wasted power and temperature fluctuations caused by these currents can prevent facilities from achieving maximum efficiency, so it's more important than ever for data center managers to evaluate their facilities and to take the time to develop a strategy mitigating harmonic current.Harmonic DistortionHarmonics are distortions of the normal electrical current waveform, generally transmitted by nonlinear loads. Switch-mode power supplies (SMPS), variable speed motors and drives, photocopiers, personal computers, laser printers, fax machines, battery chargers, and UPSs are examples of nonlinear loads. Single-phase nonlinear loads are prevalent in modern office buildings, while 3-phase nonlinear loads are common in factories and industrial plants.A large portion of the nonlinear electrical loads in most electrical distribution systems comes from SMPS equipment. For example, all computer systems use SMPS that convert utility ac voltage to regulated low-voltage dc for internal electronics. These nonlinear power supplies draw current in high-amplitude short pulses that create significant distortion in the electrical current and voltage wave shape (Figure 1). This harmonic distortion, measured as total harmonic distortion (THD), travels back into the power source and can affect other equipment connected to the same source.All periodic waves can be generated with sine waves of various frequencies. The Fourier theorem breaks down a periodic wave into its component frequencies.Harmonic currents generated by nonlinear loads increase power-system heat losses and power bills for end users. These harmonic-related losses reduce system efficiency, cause apparatus overheating, and increase power and air conditioning costs. As the number of harmonics-producing loads has increased over the years, it has become increasingly necessary to address harmonics when making any additions or changes to a facility. Most power systems can accommodate a certain level of harmonic currents but will experience problems when harmonics become a significant percentage of the overall load. As these higher frequency harmonic currents flow through the power system, they can cause communication errors, overheating, and hardware damage. Reducing HarmonicsTo determine if harmonic mitigation is necessary, facilities managers should conduct an assessment to precisely measure the harmonics affecting the data center and identify their origin. Solutions for harmonic mitigation vary in complexity and cost and can be deployed individually or in combination. The strategy that makes the most sense for a facility will vary based on the loads it supports, its budget, and the nature of the harmonic-related problems it is experiencing.Solution 1 - K-rated Transformers in Power Distribution ComponentsA standard transformer is not designed for high harmonic currents produced by nonlinear loads. It will overheat and fail prematurely when connected to these loads. Therefore, when harmonics were first introduced into electrical systems at levels that showed detrimental effects (circa 1980), the industry responded by developing the K-rated transformer. K-rated transformers are not used to eliminate harmonics, but to manage the heat generated by harmonic currents.K factor ratings range between 1 and 50. A standard transformer designed for lin[...]



Apple Builds its first Data Center in Guizhou, China

2017-07-14T14:25:54.955+08:00

Apple Inc on Wednesday (12 Jul 2017) announced that they are going to build its first data center in China, in partnership with a local internet services company, to comply with tougher cyber-security laws introduced last month.


(image)


The critical facilities will set up in Guizhou with the help of Guizhou-Cloud Big Data Industry Co. Ltd., and represents a portion of Apple's planned $1 billion investment into the province.

"The addition of this data center will allow us to improve the speed and reliability of our products and services while also complying with newly passed regulations," Apple said in a prepared statement. "These regulations require cloud services be operated by Chinese companies so we're partnering with GCBD to offer iCloud."

In April, China also announced a law requiring businesses transferring over 1,000 gigabytes of data outside China to undergo yearly security reviews, with potential blocks on exporting economic, technological and scientific data.

Apple was quick to note that its data protection protocols, viewed by some as the industry standard, will not be impacted by China's laws. The authorities also said the law is not designed to put foreign firms at a disadvantage and is drafted in reaction to the threat of cyber attacks and terrorism.

"No backdoors will be created into any of our systems," Apple said. The comment seemingly addresses fears that Chinese government agencies might use the cybersecurity law as an invitation to engage in snooping activities.


Earlier this week, Apple said it planned to open a new data center in Denmark. An earlier center in the country, announced in 2015, will come online this year.

Other foreign firms that oversee cloud businesses, including Amazon.com Inc and Microsoft Corp, already have data centers in China.

Amazon, the world’s leading provider of cloud services, adding more sophisticated services such as database management, analysis or design assistance to mobile applications, said it would build 3 data centers across Sweden, the first in the Nordic region, bringing the number of its cloud storage facilities in Europe to 10. The company on 4 April said in a statement that Amazon Web Services (AWS) would establish the centers in 3 towns, Katrineholm, Vasteras and Eskilstuna, located west of Stockholm.

“For over a decade, we’ve had a large number of Nordic customers building their businesses on AWS,” the head of AWS, Andy Jassy, said in the statement. Jassy said the Nordic region’s most successful startups including game developers, King - the creator of Candy Crush Saga - and Mojang, “depend on AWS to run their businesses, enabling them to be more agile and responsive to their customers.”

In Europe, the Internet giant Amazon already has 3 data centers in Ireland, 2 in Great Britain and 2 in Germany, according to its website. The group announced in September that it planned to open 3 more in France this year.






A Data Center Nightmare: Single Point of Failure (3)

2017-10-25T17:01:21.055+08:00

Refer to "A Data Center Nightmare: Single Point of Failure (1) and (2)"The two examples (1) and (2) mentioned emphasize the importance of several lessons that might seem like common knowledge, but slipped past all parties in the complex design and construction process of the data center.(I) It is very important to eliminate single points of failure. Had there been dual paths to the critical load and either static switch power-distribution units or rack-mounted static switches, there would have been no data center failure.(II) It is essential to use conduit and wire instead of busduct. Every electrical connection is a potential failure. The feeder busway system installed had mechanical connectors every 12 feet. Conduit and wire only have connectors at the source and at the load.(III) Only equipment for mission-critical purpose are allowed in data centers! The installed busway was inherently unreliable because human error led to one failed connection and the two additional failed connections uncovered during testing.Unfortunately, data center professionals do not necessarily have the chance to test drive a facility before it’s completely operational. At the end of the day, every data center is a unique. Professionals must take all of the right steps to make sure they anticipate future mishaps and learn the lessons of previous experiences.Five Elements of a Reliable Data CenterBuilding and designing a data center is a complicated process. The complexity is compounded not only by the building type, but by the fact that each data center is unique, built and designed to meet specific criteria. A successful project depends upon five things:Good design with input from the facility executive, builder, designer and commissioning agentGood construction, including careful selection of construction firms and subcontractors, as well as effective construction administration and documentation of field issuesSpecification and installation of quality data-center-grade materialsEffective commissioningThoughtful operational practices and timely maintenanceAbout the BlogStrategic Media Asia (SMA) is one of the approved CPD course providers of the Chartered Institution of Building Services Engineers (CIBSE) UK. The team exists to provide an interactive environment and opportunities for members of ICT industry and facilities' engineers to exchange professional views and experience.SMA connects IT, Facilities and Design.

A Data Center Nightmare: Single Point of Failure (2)

2017-10-25T17:01:50.310+08:00

Refer to "A Data Center Nightmare: Single Point of Failure (1)"Data center failures can be rooted in several sources - design, construction, maintenance, quality of material, quality of equipment, commissioning and direct human intervention. For the most part, data centers, even ones that fail, have the benefits of good design practice and intention, professional construction oversight, and high-quality craftsmanship. They are maintained according to data center quality guidelines. But a single overlooked mistake can quickly become significant issues - power and air conditioning failure - that can bring down a data center.Another story is a high-profile government data center, with a busduct-panelboard connection exploded, effectively shutting off power to approximately 15,000 square feet of the most critical computing in the facility.In this incident, the design relied on an isolated redundant uninterruptible power supply (UPS) back-up. When a UPS system failed, a static automatic transfer switch was to shift to the already-operating isolated redundant UPS and transfer the load within a quarter cycle. The system worked well and the client was satisfied with the transfer scheme and the rotary concept.Source of the ProblemWhere this system failed was downstream from the automatic transfer switch. Each of the switches fed one busduct riser and terminated directly into a main distribution panel located on each floor of the facility - one busduct per panel. A single fault on any busduct or main distribution panel compromised the critical load.As it occurred, the electrical connection between the busduct and the distribution panelboard failed and the load was lost. A single point of failure succeeded in bringing down the floor. Not until the facility’s electricians ran jumper cables from one of the intact risers and back-fed the main distribution panel did the floor have power.Why did this failure occur? The building had been designed in tight coordination between the government representative and the designer; the entire system had been commissioned and had been running with tight oversight for more than two years. What happened?The cause of the problem was the failure of a manufactured busduct connector, one of hundreds in the building. The connector joined lengths of feeder busduct via a sliding piece - designed to slide approximately one-quarter of an inch to make installation easier - and a break-away torque bolt designed to ensure that the installer did not over-torque the bolt.Although the investigation team was not asked to explain exactly why the joint exploded, it determined that the quarter-inch of play designed into the connector had actually allowed for a portion of uninsulated section of the copper busduct to be exposed to the atmosphere without insulation. The team surmised that the perfect combination of air borne dust, humidity and possibly other contaminants led to an arc that became a fault and exploded.During the analysis, the investigation team isolated each busduct riser from the static automatic transfer switch at the source and from the main distribution panel at the termination. During the megger test, the electrical forensic team discovered two additional joints that didn’t pass, clearly more candidates for potential failure. Not only did the joints not pass the megger test, two of them visibly and audibly arced while the voltage was ramped up during the testing. The joints had shown themselves to be the weak link in the system. The installed busduct technology was vulnerable to catastrophic failure.Continue - A Data Center Nightmare: Singl[...]



A Data Center Nightmare: Single Point of Failure (1)

2017-10-25T17:02:09.864+08:00

Every facility executive responsible for data centers can tell at least one nightmare scenario. Some are from direct personal experience; others are data center legends. All these stories show how hard it is to prevent data centers from failing. Every data center is unique. Every design is a custom solution based on the experience of the engineer and the facility executive.An example comes from the colocation business which is made up of real estate companies that offer tenants space, not in office buildings, but in data centers. The occupants are servers, not people. The data center real estate company brands its services based upon a promise to deliver non-stop climate control and power reliability. One moment without cooling or power harms not only the tenant, which stands to lose revenue as a result of down time and recovery time, but also the colocation company’s business model (with SLA, Service Level Agreement).A construction error that exposed a design miscalculation and a commissioning flaw can result in losing a data center. One nightmare scenario is that cabling between the generators and the paralleling gear had been damaged during construction. While being pulled through the conduits, the cable insulation had been nicked and scraped. The damage was not enough to be detected by normal meggering — a test of the resistivity of insulation — but enough to create a weak link in the mission critical power chain.If all things are correct, the loss of a cable should not be an issue. The design engineer had foreseen the potential for generator system failure and had designed paralleling gear with the programmable logic controller (PLC) programmed to handle this fault. When the fault occurred, the PLC began shutting down the entire generator bank. With the system experiencing a cascading failure, the PLC was unable to intervene.When the shutdown event was complete and the paralleling switchgear was cold, the entire site transferred to the battery. Within the design time of 15 minutes, the batteries were depleted and all customers were left without the service of their computers. The data center had failed and the colocation company’s branding promise had been seriously compromised.Why did this happen? Was it a construction error? A commissioning oversight? Could this be pinned to the owner’s design manager, the one who devised the paralleling scheme from the beginning? How about the engineering design team?There were multiple causes for the failure. In this instance, a construction craftsmanship issue revealed a design shortfall.Source of the ProblemIt is clear that even more rigorous testing before commissioning was needed. Additionally, this failure indicated that the PLC had not been programmed correctly to clear this fault condition and thus had not been commissioned with this fault scenario. And this sequence should have been part of the preventive maintenance program — a change that was made following the disaster.The design/commissioning team had not anticipated the exact failure sequence. This project would have benefited from more involvement during the design phase from a commissioning agent with specific experience in PLC programming. Additionally, a third-party reviewer with topical design and operating experience would have added value if brought into the design process.Every data center is one of a kind. The better the commissioning team can simulate real-life scenarios, the more reliable the data center will be.Continue - A Data Center Nightmare: Single Point of Failure (2)About the BlogStrategic Media Asia (S[...]

Data Center Design with Building Information Modeling (BIM)

2017-01-24T17:29:17.446+08:00

   Data center design involves a lot of timing of schedules, organization, tracking of materials and changes, etc. with complex design teamwork and coordination. For this reason, the process of Building Information Modeling (BIM) is introduced to facilitate and streamline data center project designs:Better project coordinationBIM allows everyone - architects, electrical and mechanical engineers, project managers, etc. - involved in the project to input their data into the shared model. Information is kept in one place, which helps with communication and project coordination. Faster fault detection and assessing problemsUsing 3D computer models allows the project team to detect and evaluate errors or fault easily that could cause an issue during construction. Your mission-critical building is shown in scale, and you are able to enter manufacturer details / data into a 3D model, visualizing the whole project and important issues during the design.Deeper design preparation with improved managementData centers is designed for large amounts of IT equipment supported by critical facilities (MEP - mechanical, electrical, plumbing equipment). All of these equipment & facilities have high power consumption. They must be fit properly, have proper distribution and suit certain service clearances. The routing of BIM allows electrical & mechanical (EM) designers and structured cabling system designers ( for optical fiber, high voltage / low voltage cables, etc.) to know exactly where to model for heat dissipation and adjust for any electrical duct work, and allows engineers to adjust for proper air flow.For the raised-floor, it can be especially tricky. Most floor installers do not model their installations — adjustments for structural bridging and support are typically made in the field. Creating a BIM model of the flooring allows the installer to understand where the MEP systems are located in relationship to the pedestal support systems.Flooring installers can see where they need to modify their support framing early in the process and fabricate the necessary bridging and support components to span across the MEP systems where necessary. This eliminates the time and effort it would take to do this in the field once the MEP systems are installed, thus decreasing the field installation time.By incorporating computational fluid dynamic (CFD) simulations into the BIM model, engineers can evaluate and fine tune server layouts based on the thermal modeling. You’re able to visualize how the air will flow inside the data center and see the temperature variation based on the height and how the air is moving. It’s especially helpful in being able to see how the servers in a computer room receive cold air and how hot air is removed (hot aisle & cold aisle).Smoother commissioning and operations & maintenance (O&M) tasksData centers require a series of precise commissioning process to ensure performance and reliability. Commissioning information tags for each piece of equipment and feeder can be added to the BIM model to keep a live database of commissioning process status. These information are so valuable to the operational staff, such as submittals, O&M manuals, as-built plans, balancing reports and commissioning reports. When this information is inserted into the BIM database, the information can be retained and viewed for each piece of equipment, rather than in separate volumes. Data center operators would benefit from a comprehens[...]

Control Systems for Data Centers

2017-10-25T17:04:54.878+08:00

System uptime is the crucial objective of data center operations. Distribution Control System (DCS) proposes design topologies and attributes for critical network, electrical, and mechanical systems to attain these availability. If the control system does not respond quickly and appropriately, a data center may experience a destructive and rapid failure - even if redundant chillers, air handlers and power sources have been installed.Yet in spite of these stringent requirements and the serious consequences of failure, most data centers are built with the same commercial DDC (Direct Digital Control) style control systems used in office buildings. This is in contrast to other mission-critical environments (semiconductor cleanrooms, pharmaceutical labs), where industrial controls, such as PLCs (Programmable Logic Controllers) or even Distribution Control System (DCS), perform many of the same functions.We are going to provide an overview of the main areas where industrial and commercial style controls differ, and to help data center owners and system designers understand the value to be gained from industrial PLC control systems.PLC systems offer more robust optionsCompared to commercial systems, industrial control systems feature more accurate and rugged sensors and devices, signal types and wiring methods. Industrial controllers are more robust, have higher performance, faster networks and more flexible programming capability. Redundancy options with industrial controls can address the most difficult control issues without relying on "passive automation."Passive automation involves providing distributed control in which small, inexpensive controllers can be dedicated to individual machines or processes. In this case, the loss of a single controller cannot shut down the entire facility if there are redundant pieces of equipment installed each with their own controller.Commercial systems typically use a mix of "unitary" controllers to control a single piece of equipment, with larger building controllers used for facility-wide programming tasks or monitoring general I/O points. Industrial systems use PLCs, which also come in a range of sizes and intended applications. The differences between these controllers can be discussed in terms of form factor and physical robustness, I/O type and capacity, and processor programming capability and flexibility.Performance, flexibility and higher cost characterize PLC systemsThe difference between PLC and DDC programs is essentially one of flexibility. The programming functions in a PLC are more numerous and powerful. There is a richer instruction set for math, logic and bit manipulation. Many PLCs allow encapsulation of instructions to create user-defined function blocks. This is a powerful tool that sophisticated users leverage to create simple, re-usable code. These differences allow creation of more sophisticated and powerful programs. Finally, modification of PLC programs can be done "on-line," which means the controllers do not need to be stopped if the program needs to be changed.The two types of systems conceptually can look very similar. The distinction, in a word, is performance. Industrial systems are designed for "real-time" control. Like a DDC, a PLC program looks at sensor data input, performs logic or calculations and writes outputs. However, the speed of processing and communication in PLC systems allows inputs to be read from anywhere in the system, logic[...]
