06/01/2021What high-density, mission critical data centers should look for in a compact UPS

By Ross Peringuey, Product Manager EMEA Data center density and power requirements are going up. As a result, more and better backup power is needed. Many data centers, however, have only limited space available. A very compact and powerful uninterruptible power supply (UPS) can often remedy the situation. To choose the right one, small and medium-sized data centers must consider cooling, redundancy, efficiency, architectures, and more. New applications such as high-performance computing and artificial intelligence are shaping the design and operation of small and medium-sized data centers. As energy prices rise and budgets tighten, more efficient operation is necessary. One way to reduce costs, save space, and lower energy consumption is to put more IT resources into each rack. But this creates challenges. Additional UPS requirements can cause floor space constraints unless the density of the deployed UPS keeps pace with the new IT equipment it supports. Data center architecture also influences the capabilities a UPS system should offer. Consequently, choosing a backup power solution for high-density applications requires consideration of the technologies in both the data center and the UPS. HPC, AI, and density Big data analytics, machine learning, and AI are forcing data center power infrastructure to adapt. High performance computing (HPC) platforms usually include GPUs and CPUs working in parallel to handle these new workloads. This can mean new racks full of high-end GPUs that excel at floating point calculations for applications such as medical diagnostics. Per-rack density rises dramatically with HPC, up to 20-30 kW and more. Over 50% of respondents in the survey “The Infrastructure Imperative” conducted by 451 Research reported operating high-density HPC data center infrastructure. Converged and hyperconverged infrastructure Converged infrastructure (CI) and hyperconverged infrastructure (HCI) are two further trends we are seeing alongside—and in some cases in combination with—HPC. These architectures do not impact density so much but they have implications for the reliability required of a UPS system. CI is usually seen as large rack-scale platforms that merge compute, storage, and networking as a complete solution. HCI, on the other hand, is available as 1U or 2U rack units that include a multi-core server and a local storage array. The main architectural difference is that in CI, storage attaches directly to the physical server. HCI, in contrast, shares storage across all virtual machines (VMs). As much as half of data centers are now using hyperconverged infrastructure. In these virtualized, high-density IT environments, a power outage can have a much wider impact than it would in a non-converged environment. Consequently, the reliability of the UPS and features such as +1 redundancy operation are crucial in these scenarios. Power as a major cause of downtime The most frequent cause of data center outages is power—by a considerable margin. A study by the Uptime Institute claims that 37% of outages are caused by power issues, while the next-most-frequent cause (software and IT systems) is only to blame for 22% of such incidents. One phenomenon that may be contributing to these outages is “creeping criticality”: this can occur when infrastructure silently crosses the threshold of criticality due to increasing resiliency needs while power infrastructure remains unchanged. Rising density caused by the gradual implementation of more HPC or HCI can produce this type of situation. And data center downtime is costly: over 10% of recent incidents resulted in costs of over $1 million. All the more reason to examine UPS requirements closely. The right type of UPS for mission critical data The three major types of uninterruptible power systems available today are standby, line interactive, and online. The first two may involve limitations in the way that they correct power quality anomalies from the supply such as long switchover times (25ms) in the event of an outage, which disqualifies them for most mission-critical applications in small and medium-sized data centers. An online double conversion UPS such as the new 5-20kVA Amplon RT models from Delta, however, has no switchover time at all. These devices take grid power, convert it to DC power to charge their batteries and then convert the power from the DC bus back to AC to power IT loads. The huge advantage here is that power is always already coming from the DC bus; if power from the grid is disrupted, no switchover is required. The batteries also serve to buffer transients and any voltage drops, resulting in very clean power. A UPS system that offers parallel operation can provide longer run times. Even more crucially, it ensures that power is still available if one of the UPS units or battery strings in the configuration fails. It is often referred to as +1 redundancy when two UPS systems are running in parallel. Multiple UPS systems configured in parallel is known as an N+1 architecture, with N denoting the number of UPS systems required to handle the load and the +1 as backup in the event that one of the N units fails. A parallel UPS setup is highly beneficial for mission-critical applications in fields such as banking, manufacturing, and healthcare, where unexpected downtime can have serious repercussions. Batteries are an essential component of any online UPS, but they also have a limited life. Battery maintenance and replacement is inevitable at some point. Lithium-ion batteries, however, require less frequent maintenance, have a higher power density, and can easily provide twice the useful life of lead acid. That translates into needing to replace fewer batteries, which reduces costs — a key benefit for high-density data centers operating within tight cost constraints. Bypass control lets the UPS be completely removed from the power distribution system. The ability to switch over to grid power and remove the UPS from the picture is critical in two cases: one, the UPS is defective, or two, it requires maintenance. A bypass allows the maintenance to take place with no disruption to the load. Without a bypass, the unfortunate situation can arise in which power from the grid is available, but the data center is offline because the downstream UPS is not functional. Selecting the right vendor and product for high density Having a global organization such as Delta Electronics that can deliver and service the required number of UPS systems practically anywhere in the world is a crucial advantage for data center operators. The new Amplon RT Series 5-20kVA from Delta, for instance, is a line of online double-conversion UPS systems that provide a wealth of features for enhanced resiliency and class-leading density thanks to their compact 2U form factor. This is a very beneficial combination for companies facing increased power requirements due to rising per-rack densities and limited floor space. The unity power factor, high system efficiency, hot-swappable batteries, and parallel configurations the RT series features also help resolve issues arising from higher densities. What’s more, the 5-20kVA is the first UPS on the market to offer lithium-ion external battery cabinets as standard. You can even replace a single battery instead of the entire string, while the bypass keeps systems online. Other applications will benefit from the new RT Series UPS systems as well; edge computing installations, for instance, also have limited space available and serve mission critical applications in the manufacturing and telecommunications industries. Considering the power distribution box and maintenance bypass breaker are integrated into these units, a broad range of small-to-medium-sized facilities stand to benefit from their reliability and high efficiency.

08/17/2016Powering Competitiveness in Oil and Gas

Application With the highly automated production process of the oil and gas industry, only a few operators are normally required to run the production line for one to two million tons of natural gas per year. In these circumstances, distributed control systems (DCS) or programmable logic controllers (PLC) are extensively applied for control rooms, boilers, storage, water treatment, methanol and other areas. The reliability and quality of a power supply system is by no means the primary focus, and a UPS is the safeguard to guarantee strict power protection. In addition, emergency lighting, fire exhaust, and pumps also need UPSs as a reliable power back up. For natural gas pipelines, there is a cabinet every 500 to 1000 meters for gas leakage detection, monitoring, and communications. Single-phase UPSs are also installed for critical power supplies. Besides factory facilities, UPSs are a datacenter necessity in the oil and gas sector to secure enterprise application platforms, surveillance, security systems, data storage, fire systems and more. Customer Needs Oil refinery plants are continuously running the refining process which means constant exposure to a harsh environment with corrosive chemicals, high temperatures, and high air pressures. The required reliability of a DCS system can be up to 99.9% or 100,000 hours of MTBF (mean time between failures) for complete monitoring and management. The ultimate reliability of the backup power system is always the top priority.

12/11/2015Uninterruptible Power Supplier for the Healthcare Application

Healthcare continues to make enormous strides technologically. You can see these advancements everywhere from wearable technology monitoring a patient's fitness to startups looking to improve the healthcare industry. This progress is also evident throughout healthcare centers, from hospitals to clinics. Smart Building Applications More and more medical centers are relying on technological innovations to manage their facilities. Intelligent Building Management Systems (IBMS), for instance, can coordinate everything from building operations to communications, and give hospital staff the ability to monitor, control, and integrate the proper climate for their patients through heating, ventilation, and air conditioning. IBMS also allows hospital administration to bolster security (perimeter protection, access control and digital video surveillance) and various life safety applications. e-Hospital with Intensive Information Technology In terms of data management, Hospital Information Systems (HIS) have also emerged as a big benefit for healthcare enterprises. These state-of-the-art systems provide organizations with a full suite of tools for improving hospital management, clinical tasks, and patient administration. A good HIS can also assist with operations such as Health Management Information Systems (HMIS), so administrators can better monitor and control the functioning of healthcare facilities across different locations, and assist the medical staff to improve services with readily accessible patient data. Power Supplies into Medical Devices The technology surrounding medical devices to assist and examine patients has also come a long way in recent times. Medical devices, from ventilators to MRIs, gas analyzers to centrifuges, hematology systems to diagnostic devices, have all seen strong advances for both patients and doctors alike. Protecting Critical Operations in the Healthcare Industry Given how interconnected many of these innovations are, it's no surprise that many hospitals and health care centers have integrated them into tethered systems that work together to power critical functions. For example, many healthcare facilities rely on building systems such as fire alarms and closed circuit television to monitor their facilities, which are also connected to emergency services such as fire departments. To function properly, these systems must remain at the right temperature through cooling or else they risk overheating. Data centers are another area in healthcare where attention must be paid to maintenance in order to sustain robust operations. The data centers used by healthcare organizations for storing things such as patient records, medical records and data processing applications are vital in the daily operations of a health center, which depend on energy-reliant equipment such as servers and routers to function properly. In extreme conditions, data centers in the healthcare sector require a strong contingency power system to keep them running. Add to the fact that these data centers consume mass quantities of energy, and already sustain many organizational transactions, and the ability to ensure these are as dependable and energy efficient as possible becomes paramount. Consider, also, that healthcare facilities require reliable power to operate numerous critical medical care devices. Magnetic Resonance Imaging (MRI), Computerized Tomography (CT) scanners, X-ray, gas analyzers, ultrasounds, and imaging devices are all potential candidates for a UPS installation to ensure their operational performance. Additionally, high-end advanced diagnostic systems require large UPS systems to provide adequate backup. Given all these interconnected systems, an interruption to power delivery at a hospital for even just a few seconds can disrupt thousands of interdependent operations. Aside from being a jarring experience for patients, a disruption to the power supply at a hospital can lead to equipment malfunctions, system corruption, hardware damage, and data loss. The Need for Uninterruptible Power Supplies in Healthcare Power protection systems in medical institutions have higher standards than those for commercial or industrial use. Delta offers a large array of Uninterruptible Power Supplies (UPS) designed to ensure organizations can protect their systems and applications by maintaining a consistent stream of energy, even under extreme circumstances. An uninterruptible power supply is an electrical apparatus that offers emergency power even when other sources of input power fail. These devices are different from a standby generator or an auxiliary or emergency power system in that, even in the event of a disruption to input power, a UPS will provide near-instantaneous protection in the form of energy stored in batteries. A UPS is critical in the event of a power failure at a hospital or a health clinic— a nightmare scenario for patients, doctors, and families. Under most circumstances, a hospital losing power could be the difference between life and death for any number of patients who are reliant on its systems functioning at optimum levels. Power problems may create operational or image quality issues with CT scanners, for example. MRI is one of the critical medical systems that required high quality power to operate and provide reliable and consistent imaging performance. A major power failure at a hospital could also open up the organization and its partners to legal scrutiny. Claims of negligence and wrongful death could potentially spiral into costly lawsuits, crippling the entire organization. According to a study by the Public Library Of Science, power outages at hospitals were found to impact health at many different levels, from making it difficult to receive care to maintaining what resources are available. The most common cause of power outages in hospitals are extreme natural events, such as snow and rain storms, tornados, droughts, and hurricanes. Natural disasters such as these have been steadily increasing in recent years all across the world, according to The New England Journal of Medicine, with no signs of slowing down. This creates an alarming future prospect for hospitals, which are expected to be highly operational under extreme conditions. Given the reliance of hospitals and clinics on electricity to operate, the need for robust power solutions has never been greater. And when power is lost—whether from storms, heat waves, tornados, or more—the health of thousands of patients is thrown into jeopardy. Delta's UPSs function as an essential safeguard against many potential energy issues, including voltage surges and spikes, voltage sags, total power failure, and frequency differences. By ensuring your healthcare center's systems have access to a stable power supply, even during failure events, you can greatly reduce costs while continuing to keep operations running smoothly. The Delta UPS Solution – Robust Power for Healthcare Continuity Each medical device has specific dynamic load characteristics and voltage regulation requirements that must be considered. Overall installation has to fulfill medical safety regulations. Delta's UPS engineering team must be involved in definition of additional components to fulfil regulations (like isolation transformers) and in proper UPS sizing and selection for each different type of system. For most equipment, it is better for an FAE to undertake a load study to properly understand load profiles and power specifications. The offered UPS solution should be able to support an inrush and meet overload requirements of the load. The Delta Group, as the industry leader in power management solutions, has complete UPS backup power solutions for hospitals, clinics, and healthcare centers. Delta's products offer high reliability and efficiency, as well as remote central management and sufficient battery runtime. Delta is also committed to developing advanced technology to increase the energy efficiency of our products in pursuit of environmental sustainability.

04/09/2015Uninterruptible Power Supplies in Banking and Finance Sectors

Many companies are unprepared for business disruptions caused by power blackouts and are often unaware of the actual costs and impact that they can have on their operations. While the majority of power failures from national grids last only a few hours, some blackouts can last days or even weeks. This completely shuts down production at companies and critical infrastructures such as telecommunication networks, computing services, banking and financial services, water supplies and hospitals. Need for Uninterruptible Power in Banking and Finance Sectors The pivotal role that banking and the financial sectors plays in the economic growth and stability, both at national and individual level, requires continuous and reliable services. Based on a survey made by US Department of Energy, ‘brokerage operation' and ‘credit card operation' are victims with highest average costs led by power outages. The finance industry requires enormous computing power to trade at high speed and frequency, to analyze and react to markets, and to provide customers with constant access to services and information. In the modern society, banking and financial services are not only in the traditional way like bank branches or ATMs. As the intensive application of internet, call center banking, on-line banking and mobile banking are also popular and well accepted by customers. With more and more social media, like facebook, twitter, Linked-in, are prevailing in the cyber space, social media fund transfers are also set to grow nowadays. However, IT-based financial services highly rely on solid infrastructure as the operation backbone. Each day, a staggering amount of new data must be generated, processed, acted upon, and stored. In a field notorious for high customer turnover, banks must provide optimal customer experience with minimal downtime in order to maximize retention. Data Security in Cloud-based Applications Consumers in this sector are especially sensitive to the perceived security of their data and the competence of institutions in safeguarding their personal information, so the minimization of downtime due to technical issues is doubly important. While the ease of use in interacting with a cloud-based data center can seem effortless and almost magical for the end user; businesses who provide the experience know that cloud solutions require significant investments in hardware and operations in order to remain secure, reliable, and accessible at all times. The modern digital equipment employs microprocessors that run at frequencies of up to several gigahertz, carrying out millions of operations a second. A disturbance to power delivery of only a few milliseconds can disrupt thousands of basic operations, potentially leading to malfunctions, corruption and data loss; and even hardware damage as is apparent from the IT ecosystem of banking, financial services and insurance (BFSI) sector. UPS Protects the Critical Operations in Banking and Finance UPS systems vary widely in size and function, from the smallest protecting a single computer or ATM to vast systems designed to protect large data centers. Some equipment can tolerate slight fluctuations, but significant deviation from this standard is often enough to cause damage to the sensitive components present in modern data systems in finance and banking companies. Finance segment needs to remain at the cutting edge of technology and business or risk rapid outpacing by their competitors. There are three typical applications for UPS to be used in banking and finance sectors to protect the mission critical load – 1. Powering ATMs Banking and finance companies maintain smaller systems, many of which require individual power protection. An automated teller machine (ATM) is one of the typical systems which need an online UPS to protect from possible anomalies in its power supply. ATMs can be located everywhere – bank branches, office buildings, hotels, residential areas, convenience stores and even more. There are many power challenges in ATMs. The cost challenges include the average daily power consumed by ATMs 1~3kW including auxiliary equipment, regular power outages or alternate means of power. The infrastructure challenges in ATMs lead to unstable utility power that in turn leads to communications line interruption; switch server goes down, and frozen screens lead to loss of transactions and serious customer dissatisfaction. 2. Powering Branch Automation Branch automation in banks connects the customer service desk and IT equipment in a bank office with the bank's customer records in the back office. Not only in banks, branch operations in insurance institutes and securities also need reliable backup power protection to avoid cost of power failure. There are multifarious power challenges in branch automation. Some infrastructure challenges are space constraints for alternate sources of power; servicing power equipment in remote locations and poorly conditioned environments. 3. Powering Data Centers The data centers used by enterprises in BFSI sectors for data storage and processing are vitally important to business operations. The datacenter constitutes the critical load in the daily operations of the organization, and play the role as the backbone of financial data computation, transaction system and records storage. Servers, storages, routers and switches are the key IT equipment in the datacenters. Cost of downtime due to critical load failure is extreme and the average cost per hour of downtime is increasing due to more and more adoptions of automated business operations in BFSI sectors. Data centers in banking and finance require robust contingency power systems to match the size of their operations in order to retain power for critical operations under adverse conditions. And data centers are extremely energy-consuming due to the computation of big amount of data. Besides, all branches, ATMs and on-line banking are dependent on data centers. Thus, high power efficiency and ultimate availability of UPS system will be the major criteria for CIOs to take into consideration. The Delta UPS Solution – Robust Power to Ensure Banking and Finance Business Continuity The Delta Group, as the industry leader in power management solutions, has complete UPS solutions covering power ratings from 1kVA up to 4000kVA in parallel, from single-phase to three-phase, from standalone to modular type, and from transformer-based to transformer-less UPS.

03/26/2015Centralized UPS and Distributed UPS: A Comparison

Introduction Wherever continuous power is needed, there is a need for Uninterruptible Power Supplies (UPS). UPSs act as power brokers, facilitating a continuous distribution of power throughout an infrastructure, no matter the size of an organization or how greatly its power usage fluctuates. UPS backup power strategies are conventionally deployed in two forms, centralized and distributed, and from a technical standpoint they serve the same purpose, namely, to keep power ceaselessly flowing, particularly during adverse conditions (i.e., surges, brownouts, fluctuations, total power outages, frequency differences and other power issues). While they may serve the same purpose, they fulfill it in different ways. Both solutions have distinct advantages and disadvantages, depending on the short- and long-term needs of an organization. For high-visibility and high-consumption industries, such as transportation, government/public, IT, and financial service sectors, where power supports vital applications associated with an acute internal and external sense of urgency, maintaining continuous and ample power is of paramount importance. In the following sections, we'll discuss the different ways centralized and distributed UPSs provide the flexibility companies need to scale their power protection in concert with their existing needs and future growth. Distributed UPS Distributed UPS are either mounted directly in the server rack or adjacent to it, so that (potentially) every server has UPS hardware connected to it with little-to-no space between the hardware and servers. Distributed UPS can be likened to having torches lighting the way every 15 feet of an area, whereas centralized UPS could be likened to a giant strobe light that disperses light in a 100-foot radius. If one of a decentralized UPS's torches went out, it would only darken the 15 feet that surround it, while if the strobe light of a centralized UPS was temporarily snuffed, everything would go dark, metaphorically speaking. Reliability: Strength in Proximity With an enterprise's IT network and power grid, the greater the distance between a server and its associated UPS, the greater the risk of power issues, such as: noise interference, grounding, and/or loose connections. Because distributed UPSs are mounted in, or adjacent to, server racks, shortening the distance between them, the possibility of faulty wiring developing along the power chain is substantially reduced. By providing self-contained auxiliary power all along the network, the kind of mass power disruption that can occur if a centralized UPS is deployed is circumvented. Ease of Installation and Integration Lightweight and greater portability make distributed UPSs much easier to install and move, which for companies that need more mobility in their data centers ideal. Proximity to server racks also optimizes the position of distributed UPSs to Ethernet connections. Better Cost Control for Small Organizations Because distributed UPSs are not designed to support an entire enterprise's network, but rather one server rack within the network, the initial upfront expense of purchasing this solution is considerably lower than that of centralized UPSs, which are often overkill for small- to medium-sized businesses (SMBs). Compact UPS lifespans tend to mirror those of server hardware, enabling organizations to economically synch server hardware and backup UPS upgrades. When smaller companies need to expand their backup power protection, they can opt to do so by increasing the redundancy of their system, through adding additional UPSs, as they need them, for significantly less than it would cost with a centralized UPS. Drawbacks: Inefficient Management The role of servers puts them ahead of power backup systems, which makes the space that UPSs take up (and away from servers) in server racks less than desirable. Because by design distributed UPSs are more prolific than centralized ones, they involve managing and monitoring a much larger network of resources than a centralized UPS. Therefore administering these can, at times, burden an organization's IT or data center staff. Centralized UPS As the name suggests, centralized backup infrastructure consists of one or two large UPSs placed along a server room's perimeter, at the end of a server row, or in an independent location nearby. Centralized UPSs are akin to a giant power protection net that encompasses an organization's entire network. Reliability For larger companies the single-phase power protection common of smaller, decentralized UPSs is likely to be inadequate for their power protection needs. Centralized UPS is designed with high-density server hardware needs in mind. As these typically run on three-phase power, the more robust UPS is the suitable choice, in that it can provide protection to both three-phase and single-phase loads. Servers are now run considerably higher than they were in previous eras, but hotter temperatures can dramatically shorten the lifespan of UPS batteries. The remote location of centralized UPSs protects their batteries, thereby extending their lifecycle and reducing time-consuming and costly premature battery replacement. Stable Output and Better Use of White Space Centralized UPSs generally run online, double-conversion architecture, which produces greater stability in the power curve and eliminates most power disruptions (i.e., spikes, distortions, surges). Decentralized UPS, on the other hand, is designed to react to power distortions (via line-interactive architecture), which can mean that anomalies are passed along to end devices. Additionally, in a centralized backup architecture, UPSs are kept apart from server racks, freeing up critical space for server hardware. Improved Economies of Scale To increase capacity with distributed backup architecture, data support staff must manually add additional UPSs to each server rack, a tedious and inefficient process for large-scale organizations. In addition to reducing the amount of critical server rack space available for server hardware, this also taxes data tech staff by doubling the equipment they must monitor and service. Creating redundancy with centralized UPSs is a one-step process, making it substantially less time-consuming. Drawbacks: Energy Inefficiency and Cost Implementation of centralized UPS leaves a much bigger footprint and takes a considerably greater amount of coordination to plan, install, setup, test, and launch. Companies tend to have “eyes bigger than their stomachs”, when it comes to selecting and implementing centralized UPS. Because organizations overestimate how much capacity they need from their centralized UPS, as much as 25% of the energy they consume is wasted. The excess energy generated in this all-too-common scenario manifests as excessive heat, which in turn creates greater demands on cooling systems in data centers, causing energy costs to spike. It's not uncommon for these UPS to necessitate a dedicated HVAC system to manage the additional energy output. In addition to the additional costs created by the increased demand for data center cooling, centralized UPS tends to have a substantially higher price tag than their lighter, distributed counterparts. Hybrid Solutions Modular UPSs, such as the Delta Modulon DPH Series, can create a stronger backup architecture for many mission critical operations in mid-sized datacenters. With modular UPSs, organizations can boost backup system redundancy by simply plugging in additional power modules as needed, thereby garnering the efficiency of a centralized backup system and the incremental growth (and reduced costs) of a distributed system. The fully rated, three-phase Modulon DPH Series offers the highest possible availability: 25kW to 75/150/200kW of uninterruptible power with additional 800kW capacity in parallel Mean time to repair (MTTR) is close to zero Integrates with existing power distribution on a parallel rack or the same rack Self-synchronization of power and control modules supports continuous online operation – even if control module fails High overload protection – 125% overload for 10 minutes and 150% for one minute Expands up to four units without additional hardware Built-in manual bypass eliminates maintenance related downtime ▲ Delta DPH Series UPS Alternately, a hybrid backup architecture that incorporates central and distributed UPSs can offer a solution that covers more bases and offsets the weaknesses of one system with the strengths of the other. Conclusion and Summary As the preceding discussion illustrates, determining which backup solution is best will depend on a complex matrix of variables, such as your organization's ability to monitor or manage a given backup system, the cost-benefit ratio of either solution, present server rack utilization capacity and future needs, current and projected power demands, and more technical questions, such as whether or not your server uses single-phase or three-phase power. In addition, both options have advantages and disadvantages, but by giving full consideration to each UPS solution and the needs of your enterprise, managers can better determine which of these strategies is best. * Recommended but not limited to these models.
