The Do’s and Dont’s of Data Centers

Companies and organizations that are using data centers to store vital data should make sure that they are well aware of the best practices for making sure that their data and the actual data center are both well protected from any digital mishaps, financial pitfalls and maintenance issues that might arise. You never know how much time and money you could potentially be wasting by neglecting to make sure that your data center and your data center strategy are in good shape. Brush up on the latest dos and don’ts of data centers before you find yourself in the middle of a data center disaster.


DO Understand the Importance of Data Center Maintenance


Much like automobile maintenance, data center maintenance is one of those things that’s very tempting to put off until a more convenient time. Unfortunately, disaster seems to strike at the most inconvenient time. Think of how much time and money you can potentially lose should your data center ever incur downtime. Without keeping a close eye on them and performing regular maintenance, your servers, cooling systems and other vital components of your data center can suddenly fail, bringing your entire operation to a standstill. You should also keep a close eye on performance degradation since it can lead to a system wide crash if your system isn’t kept in peak condition.


DON’T Forget About Water


While you might think that water is the last thing that you need in a roomful of sensitive electronics, it’s actually vitally important for the proper operation of data centers. The reason for this is that data centers generate a lot of heat and need to be kept cool so that they can operate smoothly. Some of the largest data centers utilize evaporative cooling in order to keep the center from overheating.


That being said, you also want to do what you can to conserve water and money on cooling costs. Remember that every single watt of power that’s used in your data center is converted into heat that has to go somewhere. Only use as much energy as your data center needs so that you only use as much water as you need.


DO Take a Close and Realistic Look at Your Consolidation Plan


If you’ve got a data center consolidation project in the works, you’ll want to make sure that you have a realistic plan in place rather than a plan that’s a little too well thought out. What this means is that you want to have a sound project plan, funding perspective and staffing projections, but you don’t want to over-plan so much that you wind up crippling your progress.


An abundance of checkpoints, refining processes and controls can lead to several roadblocks. When consolidating your data center, plan from the lessons that you’ve learned in the past as well as the most effective and current data center practices. Sometimes it’s best to simply jump in and see what happens.


DON’T Neglect the Best Tools


There are certain tools that you can put to good use when it comes to making sure that your data center is operating at a hundred percent. For instance, infrared scans are a good way to pinpoint high temperatures and several other data center problems. You should also consider implementing computational fluid dynamics (CFD) so that you have a way to model the proper distribution of heat and air flow, both of which allow you to make adjustments to your IT infrastructure. One of the more basic tools that will serve you well is disc space. The right amount of disc space can go a long way in helping you to avoid some of the more major data center issues.


DO Consider “Free” Cooling


Running a data center isn’t exactly the least expensive business operation, which means that you’ll want to save money and utilize free resources where you can, even if they aren’t exactly as free as you might hope. Updated humidity and temperature guidelines make it possible for data centers to operate at greater temperatures, which means that they won’t need as much cooling as they did before. Something else that this means is that data centers are one step closer to having free cooling in the future. With free cooling, centers won’t need as large of a cooling infrastructure, which means that their capital costs as well as their energy consumption will be lower. Keep in mind that free cooling won’t be completely free, but it will most certainly be less expensive than some of the more traditional cooling methods.


DON’T Over or Under Utilize Tools


Some clients love using as many data center tools as they can, but more often than not this does them more harm than good because of the duplicate data, a lack of a formal support infrastructure and various interfaces. By using several tools, you increase your risk of data center error since any underlying data you have is no longer viable.   


On the other hand, you don’t want to fall into the trap of thinking that data center tools are overrated and unnecessary. Even though the basic tools will most certainly get the job done, they aren’t optimized for a large scale or specially designed data center. In this case, it’s best that you find a well-balanced middle ground where you only have two or three tools that complement each other.


Taking good care of your data center all starts with setting a good foundation. Figure out what the basic demands of your particular data center are and work your way up and out from there from the root of your data center to the fruit of your data center.

Ten Popular Myths About Power Protection Put to Rest

Just because a notion has been around for a long time doesn’t guarantee that the idea is true. Unfortunately, this is the case with many of the ideas that affect the way data centers measure, use, and conserve power. The most common myths regarding data center power protection are guilty of leading to increased spending and reduced efficiency. Here are ten of the most common myths and some clarifications:


  1. 1.     Utility Power Is a Clean, Dependable Source of Energy


The truth is the actual voltage of electrical power can vary quite a bit. According to current U.S. laws, the amount of voltage can vary between 5.7 and 8.3 percent. A data center manager may believe that the facility is receiving 208-phase voltage, but the actual number could actually range between 191 and 220 volts. This type of utility power is also prone to power outages. The potential is that a data center might suffer from a power outage up to nine hours every year.


A good solution to this problem is to develop a Combined Heat and Power facility to improve the quality of data center power and increase dependability.


  1. 2.     Brief Power Outages Aren’t a Problem


Experienced IT professionals understand the significant risks that power outages pose, even if the power is only out for less than a second. That brief interruption make IT equipment unavailable for a much longer period of time – maybe even stretching into days. During this time, the data center can lose system integrity and be at risk for significant financial losses.


Data centers generally have a backup plan in place from the very beginning. Redundancy in power supply and a dependable power source are two factors that can help prevent outages. An uninterruptible power system (UPS) may be another valid solution.


  1. 3.     The Data Center Is Protected Well Enough by a Single Backup Power Supply


While it may be true that a backup power generator is a critical element of protecting the center from power outages, this one source of power is not enough. In that brief moment when the power flickers off before switching to the generator, damages could occur and hours of productivity could be lost to the reboot cycles. Another scenario involves the UPS without a generator. Any extended loss of power could put the data center at risk once the batteries of the UPS run down. The clear solution to this problem is to maintain both the generator and the UPS.


UPS Myths


Several myths relate directly to the UPS of the data center:


  1. 4.     Every UPS has the same battery runtime and service life.
  2. 5.     The UPS load doesn’t affect efficiency.
  3. 6.     A working UPS doesn’t need servicing.


There are a few other similar, but misguided, ideas surrounding the use of the UPS. Too many data center managers develop a false sense of security once the UPS is in place. Instead of getting too comfortable, managers should include the UPS in a bigger backup plan, monitor and service the UPSs consistently, and keep accurate records, such as the capacity of each power bus and how much of that is being used.


  1. 7.     Data Centers Can Afford to Lose a Few Points When It Comes to Energy Efficiency


Sometimes data center managers believe that improving their energy efficiency by just a few points isn’t going to save the center much money. However, modern systems are both energy-efficient and very scalable. This means that replacing older technology with new technology, and gaining those few points, can save the center both kWs of power, thousands of dollars, and reduce the amount of emissions that the center gives off. Look at a 1-MW data center with an aging UPS. A 10-year-old UPS might waste at least 120 kW while also adding unnecessary heat to the facility. Replacing that system with new UPSs will recover the power, reduce the wear and tear on cooling systems, and reduce costs and emissions.


  1. 8.     Power Usage Effectiveness (PUE) Is An Ineffective Measure of Efficiency


The most common objectives to using PUE for the data center is that measuring power usage can be difficult. In fact, there is more than one way to obtain these measurements. Most data centers resort to measuring just a few points (possibly the servers and the UPSs) without measuring the amount of power consumed by cooling and/or distribution losses. In order to keep PUE numbers low (about 1.0), measurements must be taken.


  1. 9.     If Low Temperatures Are Good, Even Lower Temperatures Must Be Better


Data center managers closely monitor the temperature of the center. The equipment, hardware, and technology should be used within a specific temperature range; otherwise the hardware could fail altogether. However, when the temperatures fall too low, there are no further savings, no increased efficiency, and no prolonged life. By reducing the temperatures beyond the recommended point, data center managers are simply wasting money.


  1. 10.  The Use of Solid-State Disks (SSDs) Can Reduce the Consumption of Power

This myth came about because the SSDs do consume less power than a traditional hard disk. However, the SSDs also have a maximum draw that falls right around 10 watts. With this in mind, the 15,000 rpm drive uses a great deal less power than the 4 watts of the SSD. It is also important to remember that the disks cost much more per gigabyte (10 times more), making it hard to justify their purchase.


Instead, IT managers should choose to maintain and up-date their other equipment to improve efficiency.


Investments and Rewards


Data centers, just as any other business, invest a great deal in the power needed to remain operational. Anything that puts that power at risk might undermine the well-being of the entire center. With efficient UPS hardware, redundancy in the backup plan, and careful record-keeping, data center managers should be able to avoid these popular myths and operate a successful center.

Top 10 Ways to Ensure Your IT Equipment Is Managed Effectively

Data centers all over the world have filled a very important role in this modern computer-linked society. From the modest server room to the corporate level data center, companies of all sizes use these centers to store sensitive information and critical data. For those IT professionals who are responsible for the running the IT equipment, staying on top of efficiency might take up a good portion of their time. In general, effective management of the equipment comes down to consistent monitoring and accurate measurements:


  1. 1.     Install a Reliable Network of Temperature Sensors


Any amount of IT equipment will generate some heat. A small laptop at home is as sure of adding to the room’s temperature as a much larger IT department. As the need for IT utilization grows, the need for cooling systems has also grown. Now, in addition to handling the IT equipment, IT professionals must also be aware of the associated cooling systems. The temperatures between racks at a data center or generated by different types of equipment can vary widely. A network of data sensors is a good way to monitor and manage the temperature of equipment, ensuring that the equipment stays within ASHRAE  (American Society of Heating, Refrigerating, and Air Conditioning Engineers) recommendations and protecting the equipment from over-heating.


  1. 2.     Monitor Power Usage at Various Points


There has been a great deal of discussion concerning the efficacy of power usage effectiveness (PUE) measurements. These measurements can be difficult and time-consuming to take, leading some professionals to believe that the measurement is not important. The PUE is typically found by dividing the total facility energy by the IT equipment energy. The best PUE is 1.0. This measurement answers the question, “How well is the equipment using the amount of power being delivered to it?” Without taking a PUE measurement, it can be very hard to determine whether or not power and equipment is being used efficiently.


  1. 3.     Automate the Collection of UPS and PDU Data


With an awareness of the difficulties present in obtaining the PUE measurement, use an automated method of collecting data from the UPS and the protocol data unit (PDU). Energy efficiency monitoring equipment, hardware and software, can reduce the consumption of energy, while at the same time improving the productivity of the IT equipment.


  1. 4.     Prevent Threats to Rack-based Equipment


In a data center with multiple racks or even a large IT department with at least one rack, there are some common risks. These include:


  • Malicious tampering
  • Accidental damage
  • Too much humidity
  • Inappropriate temperatures
  • The presence of smoke


Maintaining a constant visual upon the racks may not be possible, but the use of a monitoring system can alert IT professionals to open rack doors, increasing temperatures or humidity, and the presence of other threats. Connect a monitoring unit to the central monitoring system for faster response times.


  1. 5.     Detect the Presence of Liquids and Fluid Leaks


Just about any owner of electronics knows how dangerous just a small amount of liquid can be. A few drops of water on the motherboard can render a computer completely useless. One water leak in a data center can lead to thousands of dollars lost due to downtime and equipment damage. Both of these situations can lead to data loss, frustrated customers, and decreased productivity. A system for monitoring leaks should be established around water lines, glycol piping, drain lines and condensate drains, unit drip pans, and the humidifier supply. This system can be set up with the central monitoring system or as a stand-alone system.


  1. 6.     Install Intelligent Control of Precision Cooling


Maintaining a precise temperature inside an IT department or data center is crucial. Without intelligent controls, maintaining the precise temperature and level of humidity would be difficult and impractical. An intelligent control system will help the units to work uniformly instead of in competition with each other.


  1. 7.     Include Intelligent Control of Critical Power


The same reasons for monitoring temperatures with intelligent controls may be used for monitoring critical power with the controls. The digital controls can be used to optimize the specific performance of uninterruptible power systems (UPSs). The intelligent controls can also manage the switch between traditional operation and the backup systems used when outages or overloads occur. Additionally, the controls might monitor the conditions at the site.


  1. 8.     Utilize Alerts and Alarms


Protecting the IT department from any downtime, even a fraction of a second, is crucial for equipment efficiency. Even the briefest power outage can disrupt systems, prompt a reboot, and lead to several days of reduced productivity. With a reliable system that provides notifications of any event that might lead to a power failure, IT professionals can respond to those sources of trouble before an outage occurs.


  1. 9.     Keep an Eye on Battery Levels


Data centers routinely use a battery monitoring system to protect against power outages. Without this maintenance, the center runs the risk of losing UPS system power failure when that power supply is most critical. Use a monitoring system to monitor the health of the batteries in all UPS units.


  1. 10.  Consider Remote Management or Monitoring of IT Equipment


By shifting the burden from internal IT personnel to a remote source, a devoted organization can bring combined resources and expertise to the task of measuring and monitoring the use of IT energy. As troublesome issues arise, the remote organization can handle the IT crises while other professionals can focus on responding to trouble on location. This suggestion may not be appropriate for all IT departments, but might be an option to consider if the IT staff is already struggling to complete necessary tasks.


Whatever the size of your IT department, keep in mind the common adage, “if you can’t measure it, you can’t manage it.” This holds true for the monitoring and measuring involved with IT equipment efficiency. With reputable and accurate monitoring systems, the IT professionals can better track and maintain the efficiency of their equipment.

Becoming Energy-Efficient Through a Data Center Energy Audit

Green is in, and there is little doubt that companies that can show they are striving to be energy efficient are more productive. To stay proficient, older data centers need to find ways to become more energy efficient, and newer data centers need to implement energy efficient protocols from the outset. The numbers show that proper implementation of energy management can save data centers millions of dollars each year. In order to find these energy management ideas, data centers need an energy audit. There are different types of auditing processes to determine data center energy usage. Understanding the standards, downfalls, and successes of this process is important in understanding its importance.


Types of Energy Audits


There are three different ways to carry out an energy audit, including a walkthrough audit, comprehensive audit, and investment grade audit.


A walk-through is by far the least expensive and time-consuming of the three. However, a simple walk-through audit can easily overlook opportunities for energy savings. Sample readings and measurements recorded generally include:


  • Power
  • Lighting levels
  • Thermal comfort


Normally, an auditor walks through the facility and reviews energy data for the past one or more years to determine opportunities for energy savings. A comprehensive audit may be recommended if the auditor feels that the facility could benefit from one.


A comprehensive energy audit is considered the standard. It usually involves gathering energy data of a facility for three or more years and conducting a detailed investigation into the facility’s energy use process. Since more data is collected and examined, more energy management opportunities may be discovered than a simple walk-through would provide. Since this audit takes more time and manpower to analyze data, it is more expensive than a walk-through.


Investment grade audits are an even more exhaustive process to leave no energy-saving stone unturned.  Everything involving the facility’s energy usage and footprint for the past several years is assessed to find opportunities for energy savings. Detailed energy models are created to illustrate the effect energy efficient actions could have for the facility. It is the most detailed and time consuming of the three audit processes, and therefore more expensive.


Assessing Data Center Energy Usage


The process for assessing data center energy usage starts with data collection. The amount of data collected depends on the type of audit being performed. It is common for data centers to undergo a comprehensive audit that examines three years or more of existing energy usage information. An energy efficiency model may start to form from the data collection alone. An auditor will need to visit the site to document in person energy efficient actions that may need to be taken. It is common for the auditor to assess areas such as:


  • IT equipment and software
  • HVAC
  • Electrical power chain
  • Air Management
  • On-site energy generation


The product of any type of energy audit is the energy audit report, which examines what the current cost of running the data center is and compares it to the projected cost after energy efficient actions are implemented. The report includes steps to take to lower energy costs. Some energy efficient implementations cost money at first, but ultimately serve to save data centers millions over the years.


Standards for Assessing Energy Usage


Ultimately, during the energy audit process, the goal is to produce a number to evaluate the data center’s Power Usage Effectiveness (PUE). PUE is usually quantified by taking total facility energy and dividing that number by the IT equipment energy. The resulting number can be anywhere from 1.0 to infinity. A score of 1.0 means that a data center is operating at 100% energy efficiency. Typically, older data centers generate a PUE of 2.0 to 2.5 (80-85% efficiency). However, there are many data centers (some in that older category) that have managed to get their PUEs to 1.6 or better. Newer data centers that focus on optimal IT power delivery and cooling are more likely to get closer to achieving a score of 1.0.


Common Downfalls in Energy Efficiency During an Energy Audit Assessment


Although PUE assessment is considered standard across the board, it is not an infallible process. There are certain factors that can directly affect the score that a data center receives during an audit, including:


  • The age of the data center
  • Type of processing
  • Type of cooling
  • Temperature levels
  • Location of CRAC units
  • Ventilation


PUE can differ from the actual total energy usage levels of a data center. When a data experiences down time on IT devices, the total energy usage also goes down. However, unless there is a proportional drop in the infrastructure energy and cooling capacity, the PUE number actually goes up, worsening energy efficiency.




It might sound complicated, but there are plenty of data centers that have already undergone energy audits and seen success with energy efficiency protocols. Google and eBay are the towering success stories that have seen PUE levels of 1.2 and 1.4 respectively. More recently, digital realty major DRT has released information that it has dropped its PUE level down to 1.6, saving the company $6-10 million per year at two data centers.


The energy audit process for a data center uses careful analysis of energy usage to determine where energy costs can be efficiently reduced. The ultimate goal is to find ways for a data center to drop its PUE level to as close to 1.0 as possible. Significant benefits generally await those data centers that can find ways to be more energy efficient. For those companies looking to stay in the business effectively, a comprehensive energy audit may be in order.

Is it a Data Center Emergency or Just A System Notification?

In the office of today, a lot of machines beep, ring, and create various alarm notifications. Nearly everything from the copy machine to the coffee machine has an alert to bring attention to things such as low toner, finished cycle, or some other status. Unlike the pre-computer offices of the twentieth century, where the only bell usually heard was from the typewriters as the secretaries reached the end of the line, modern offices have a lot of minor little alarms – and of course, a few big and very important alarms, as well. For instance, just one device, the Uninterruptable Power Supply (UPS) that helps to keep a steady power supply to the company data centers, has both small, less-important notifications, and more urgent alarms. Knowing the difference between a status update or alert, and a system critical alarm that requires user action, is one key to keeping an office operating smoothly.


What is That Alarm About?


For workers who are not in the IT department, the computer systems of the office can be both familiar and intimidating. On the one hand, nearly everyone in the company uses the workstations, tablets, laptops, and other devices that are part of operations. On the other hand, though, the complicated computer programs, algorithms, functions and electronics behind the familiar facade of the keyboards and screens that all workers use everyday is mostly not well understood by the average employee.


When the company’s data center UPS activates, for instance, in the event of a power loss for any reason, it will trigger a notification. Some people become alarmed and feel a need to call the experts when they see such a situation. In most cases, though, the truth is that the system worked just as it should, and there is not a problem to report. The UPS is there to keep power supplied in the event of power interruption in the system. If there is an unusual event where the main power will remain unavailable for a longer time, it may be necessary to take immediate action when the UPS system kicks in. Generally, though, full power will soon return, and the system can return to normal operation. In that case, there is no need to call the IT experts, as the system is working properly and doing its job.


Power to Electronics


The computers and devices that smooth the flow of much information and work today naturally require a steady and predictable supply of electricity. Electronic machines can be very sensitive to sudden power bursts or fluctuations. Despite significant advances in power grid technology, the fact remains that in the real world, power systems do not provide an exactly constant, perfect flow of electricity. In reality, the amount of electricity ebbs and flows and surges, depending on needs, demands, and production in the system. While the slight variations in power supply are not harmful to most electrical appliances around the home or office, the very sensitive and sophisticated computer equipment can be damaged or ruined by power supply fluctuations.


Realizing the risks to equipment and data that can come from power surges or sudden unexpected power outages, electronics manufacturers created solutions in the form of UPS devices, as well as Power Distribution Units (PDU). For computer-sensitive companies, a PDU can help to smooth the flow of electricity to various devices, ensuring that none gets hit with a spike of energy that can burn out electronics, and that none are lacking the power they need to do their jobs. Many large industries rely on PDU to moderate the flow of power to a variety of electronic devices. Naturally, data centers are one of the primary users of PDU, but they are also utilized by government operations, hospitals, as well as many data-intensive industries.


The More You Know. . .


While not every employee in every company can be a computer expert with a thorough working knowledge of the ins and outs of the system, it helps to have employees who are thoroughly trained and knowledgeable on the operations that they will come in contact with in their work. Particularly for parts of the system that are not used everyday, but that can be vital in the event of power system problems, such as the UPS and possibly the PDU if in use in the company, it is useful to have thorough training in the basic workings of the system and the various alerts and notifications that the devices may provide in different situations of normal operations.


Workers who are informed of what to watch out for and trained on the various levels of warnings and notifications that will inevitably come from the computer and its power backup systems are generally more confident and less prone to call for expert help that is often unnecessary and costly. One of the key mission functions of a company’s IT operations is to minimize downtime and promote efficient, productive use of the electronic devices that the company uses. The better that all employees can understand some of the more mysterious inner workings of the machinery that tend to be out of sight and out of mind, the more likely they are to be productive and pro-active in resolving small issues in-house and in the simplest way possible. When workers know which notifications are indicators of a system working well and resolving internal problems adequately, and which alarms require quick action to maintain data stability and computer operations, then they can perform their own jobs better, knowing the computers are there for them when they need them.

Emerson UPS Systems Product Review

When Power Backup Is Required, Emerson UPS Systems Offers a Variety of Products

Emerson Liebert UPS Product ReviewAs industries become increasingly reliant on computer technology to perform daily tasks, protecting integral company data and equipment becomes more and more urgent. One way to ensure that operations are not affected by an unexpected loss of power is through uninterruptible power supplies, also known as UPS.


Emerson UPS systems are one provider of devices intended on saving crucial company info, as well as ensuring that computer networks can be shut down in the appropriate manner in the event of a full-scale power outage. In some cases, the ability to correctly shut down computer systems can be essential to maintain the integrity of a computer network. Power outages can not only result in a loss of important data, they can also have a disastrous effect on the computing hardware a company needs to perform daily functions.


Company Background


Emerson UPS systems is a leader in offering effective computing solutions that address a number of relevant issues related to power backup. Emerging in the early 2000s as a division of Emerson Electric Company, the primary goal of Emerson UPS systems is to offer user-friendly methods of ensuring a company’s computer bank remains secure no matter what may occur.


Emerson UPS systems specializes in devices that offer auxiliary power solutions in the event of an outage. Causes of outages can include everything from inclement weather to malfunctioning equipment, and as a result of these occurrences vital hardware and devices may be damaged irrevocably. The Emerson UPS systems’ product line includes uninterruptible power supplies that can prevent the loss of crucial company data, as well as protecting costly hardware from being damaged by an unexpected power outage.


How Does UPS Work?


Unlike standard auxiliary backup systems, uninterruptible power supplies feature a near-constant source of power that can allow vital operations to continue in the event that a power outage is imminent. This can be extremely important for select industries, where loss of power can contribute to everything from steeply declining revenue to public safety issues.


A UPS has a relatively short lifespan, but in most cases this period is long enough to enable vital backup power to be initiated. A UPS can also offer time to perform crucial steps to ensure data remains protected before a full-scale power outage occurs. This window of opportunity can make all the difference between saving relevant data and losing this information forever.


Types of UPS Products Offered by Emerson UPS


Depending on a company’s needs, one UPS product may be preferable to another. The following are a few of the items offered by Emerson for the express purpose of supplying backup power in the event of a facility-wide outage:


  • Desktop/Workstation UPS – Depending on the industry, a single workstation could be tasked with performing many critical operations that may be impeded in the event of a power outage. Fortunately, workstation UPSs offer a continuous power source for a range of hardware. Such backup power suppliers offer smaller range of capability, making them more affordable to small business entities and the like.


  • Rackmount UPS – For those at the helm of data centers and other computer-intensive businesses, rackmount UPS systems are preferable because they offer the ability to power more devices from a single piece of hardware. In the case of larger computer networks, such as those necessary for the IT industry or other large-scale operations, a rackmount system can offer the level of protection necessary to ensure daily functions are secure.


  • Network UPS – For many companies, a functioning computer network is integral to maintaining efficient operations. If a network is rendered inaccessible even for a relatively short period of time, it can have disastrous effects on future operations. A network UPS can ensure crucial company networks remain accessible no matter what occurs. Network UPSs can offer auxiliary power to things like servers, routers, bridges, hubs, and other vital network components.


  • Power Management Systems – For those entities with a number of computing devices, power management can be an important issue. Thankfully, there are devices that can ably handle power management to ensure more efficient computer usage. These devices are tasked with dispersing power on an as-needed basis. As a result, power will be used more efficiently, entailing less wasted energy and more resourceful computing overall.


Common Uses for UPS


While not every company or industry may be in need of a UPS, they can be highly beneficial in a number of circumstances. Nuclear power plants are just one example of the important role a UPS can play. Most of the operations at a power plant are automated; this means a failure of power can result in a large-scale catastrophe. As a result, a reliable form of auxiliary power is necessary to ensure important functions can be performed without interruption. A standard source of backup power, such as those offered by auxiliary generators, may not be sufficient in this instance.


Other industries require consistent backup power for different reasons. Brokerage firms necessitate constant communication to stay abreast of market trends and developments. Therefore, a power outage could have devastating financial results on a firm if connectivity can’t be restored right away. A UPS offers a firm enough time to make alternate power arrangements before connectivity is lost. Of course, these are just a sampling of the types of companies and industries that would benefit from a reliable source of backup power.


Computers are a necessary component of the business world these days, and companies must ensure both their equipment and data remain protected. Emerson UPS systems offers an array of devices that can mitigate the ill-effects caused by large-scale outages, no matter the cause.

Logically, almost no data center that will be fully functional for approximately another year would warrant a complete overhaul of power management systems and redundancies. However, a new data center could benefit from many different ways by investing in top UPS Systems from a reputable manufacturer.

New data center construction is notoriously costly. The latest energy-saving UPS Systems from Eaton can realistically diminish the amount of outside power used to the point where the UPS Systems save data center owners cost without increasing liability in the event of a power surge. In addition, advanced UPS Systems from Eaton can help new data centers ensure adequate power supply in the event the main grid cannot fully support the data center in the next several years due to unanticipated population growth in the area.

Simplify the Data Center Construction Process

Data centers have historically been designed to work within the parameters of existing utility infrastructure and existing utility capabilities. More advanced options for power supply and power management from Eaton can help mitigate the direct impact a new data center has on existing infrastructure.

The Right Redundancies at the Right Cost

A complete overhaul of the UPS systems and power management systems for data centers is often realistic when all other mission critical elements are in excellent condition. Additional redundancies can support older data centers under the right conditions, and the cost savings can be substantial. A slightly outdated data center may only need a few simple UPS redundancies that have a low footprint to be fully-functional for another several months.

Cost and Reliability Matter In Data Centers

The cost of downtime due to an ineffective UPS system could be astronomical. Cost should be calculated over the anticipated lifespan of a new or existing data center, and risk should be mitigated. Cost due to loss of power can impact more than equipment replacement and repair. Numerous data centers can suffer cost due to downtime in the form of lawsuits, legal fees, and any payments mandated. Poor reliability due to poorly manufactured UPS products can be a substantial monetary risk for data center owners and operators.

Eaton Products Offer Individualized Data Center UPS Solutions

A critical part of innovation is looking at present needs in addition to future needs. Eaton offers a variety of UPS Systems and solutions that can support mission-critical data center functions for current data centers as well as cutting-edge data centers that are not yet under construction.

A Power Distribution Unit Can Optimize Computer Operations

Computers are at the center of many successful business operations, and there are no signs that this trend will be abating any time soon. Because computers are so integral to the business world, it’s imperative that precautions are put in place to ensure that daily operations can continue unimpeded, no matter what may occur.


A power distribution unit, also known as a PDU, is one such technology intended to simplify businesses operating via large-scale computer networks. This is especially true of things like data centers, which often contain an array of devices necessary to perform key operations. A PDU is tasked with providing power to these many disparate devices from a central location. As a result, PDUs must contain certain protections to ensure all devices remain powered sufficiently for everyday functions to occur.


What Is a PDU?


As briefly mentioned above, a PDU is responsible for distributing electrical power to a number of different devices. As a PDU allocates power usage, it also ensures that unexpected power outages do not damage important hardware or result in a loss of pertinent company data.


While PDUs can be used in a number of industries, they are most commonly seen in data centers. This is because data centers are often comprised of numerous computer devices, all of which require a reliable source of power to maintain integral daily operations.  A PDU can efficiently power many devices concurrently, while also ensuring that these devices remain in operation in the event of an outage.


Types of PDUs


  • Basic Units – The ubiquitous power strip that is now a staple of every home and office is merely a simplified version of a PDU. Power strips serve as a centralized location to disperse electricity to a number of devices. Many power strips even offer protection to devices in the form of surge protectors, which can cause electrical items to shut down before being damaged by an unanticipated spike in power. While other types of PDUs are far more sophisticated, the principle remains the same.


  • Rackmount Units – Rackmount PDUs also disperse electricity to many different devices. However, these larger models can often accomplish other tasks which makes operation safer and more efficient. Unlike standard power strips, a rackmount PDU can allow for intelligent power dispersal. This permits power to be used more efficiently by connected devices, which not only improves operation but also cuts back on wasted energy. A rackmount model can also be accessed remotely, making it beneficial for companies who may have offices spread out over a great distance.


  • Cabinet Units – Cabinet PDUs are most often found in data centers, which often contain a large amount of hardware. As a result, cabinet PDUs are typically far more complex than their less-powerful counterparts. A cabinet PDU may require many sources of high-current power supplies in order to successfully maintain many different devices. Cabinet PDUs also include things like circuit breakers, as well as control panels dedicated to monitoring power distribution.



How Do PDUs Work?


Electrical currents are supplied to the PDU, which then distributes this power to devices accordingly. In some cases, PDUs can be accessed remotely, which allows the operator to change the way power is distributed to different devices. This can be helpful in the event that the number or type of electronic devices changes, or as a means to deal with impending outages or other issues that may affect computer hardware.


PDUs can also differ in the amount of power they can handle, ranging from smaller units to those tasked with allocating power to numerous devices. Many PDUs include means of mitigating the effects of large-scale power outages, which is useful for both protecting data, as well as vital computer equipment.


Who Needs PDUs?


While many businesses can make use of some form of PDUs, for certain industries these devices are crucial. The following are just a few industries and organizations that require PDUs as a part of daily operations:


  • Government Entities/Organizations – Government-run computer networks need to be accessible at all times. For this reason, proper allocation of power is crucial maintaining reasonable operation.


  • Schools – Schools often entail a large bank of computer systems necessary for day-to-day assignments. As a result, a centralized source of power can be a smart choice for keeping all devices up and running, no matter the demand.


  • Hospitals – As technology advances, so do the means in which patients are treated for health issues. Because many hospitals are now utilizing computerized systems, a reliable power source is important for maintaining the health and well-being of patients.


  • Brokerage/Trading Firms – PDUs can ensure that workstations crucial to accessing market information remain online no matter what. Even a few hours of down time can result in financial devastation for a brokerage firm.


Benefits of PDUs


PDUs can be beneficial to companies for a number of reasons. While they primarily allow for a more efficient dispersal of power to many devices, they can also serve as a fail-safe in the event that power is lost unexpectedly. PDUs can also be helpful for those companies that wish to closely monitor their power consumption. Thanks to the monitoring features included within many models, operators can devise ways to more efficiently use allotted power, resulting in far less waste. In many cases, PDUs offer convenience and efficiency in one package.


Whether you are the helm a large-scale data center or a small business, a PDU can prove extremely useful in a number of circumstances. For those companies that rely heavily on technology for daily functions, PDUs are a natural choice.

Comprehensive Data Center Spring Cleaning Checklist

Spring Cleaning Checklist

There are numerous mission critical elements to all data centers, and regular maintenance is integral to minimizing downtime and keeping all mission critical systems running.  Arguably, it is best to take a top-down approach when itemizing which data center components are most integral to successful operations.  The redundancies and numerous automated facility support systems as well as interdependent operations need to be addressed for viability before downtime, or in some instances permanent data loss occurs.

It is also important to note that optimal data center construction and maintenance can provide some of the top results for data center owners.  Recent research by technology research firm Gartner suggests that most current data centers will be obsolete in less than 10 years. Others argue that the lifespan of the average fully-functional data center may be as little five years. Maintenance, testing, and general spring cleaning can help increase the lifespan of almost any data center substantially.

Spring Cleaning Checklist For Data Centers

Below is a simple, itemized checklist for what items should be addressed when maintaining data centers.

ü  Specialized Testing of the Facility

It is almost always more cost-effective to invest in specialized testing of data center systems in order to adequately repair or maintain mechanical devices and hardware that is integrated with critical operations than to wait until several operations have been damaged or failed.

Specialized testing can also help identify if additional redundancies are necessary due to data center growth or potential overuse of the larger power grid the data center is connected to. In addition, facility roll-over testing can accurately identify if all backup systems will be fully functional in the event of a power surge or full power outage.

Generators and Power Supply – Power surges and power outages can be adequately addressed with redundancies. However, all automated generators that provide an alternative power source need to be fully-functional and work in conjunction with alarm systems. In addition, load bank testing can ensure that all generators are functioning at a normal capacity.

Infrared Thermography Testing and Troubleshooting – Infrared thermography testing can identify atypically warm or cool areas throughout a data center. The cause of the temperature change can be traced back to components that were not properly installed, electrical issues, or overloads, or loose circuits.

Specialized HVAC Testing and Installation – HVAC testing and design for data centers is integral to supporting basic functions and extending the lifespan of all mechanical components. Optimal temperatures ensure that hardware does not melt or crack, and optimal humidity reduces the risk of corrosion as well as other types of damage.

Testing and troubleshooting is the first step to identifying which data center components need to be repaired or replaced.  Other components can be replaced or removed for increased space.

ü  Replacements and Installations

Routine replacements of inadequate or semi-functional components and installation of new components can help extend the lifespan of data centers as well as offer increased security.  In addition,  routine replacement and installations by data center experts can further ensure that downtime due to various types of interruption is less likely.

Battery Replacement – Battery failure is the leading cause of system downtime due to UPS load loss. A single bad battery in an entire string can cause system failure during a power surge or power outage. Low quality batteries can have substantial consequences for data centers, and they are one of the most important elements to regularly replace.

Additional Power Redundancies – Large data centers located away from main power grids may experience the need for new generators and other sources for power redundancies.  New developments can put strain on an existing power grid, or planned infrastructure could jeopardize the viability of current power plans for data centers. Utility companies often need to be contacted by data centers that consume a notable amount of electricity in order to continually and accurately assess available resources.

ü  Optimizing Usable Space

Secure data disposal is necessary after a certain point in time. Data racks should not be cleared haphazardly due to potential ramifications with interruption of optimal airflow or other concerns associated with physically altering the design of the data center. One of the easiest ways to increase usable space is to get rid of trays that are no longer in use. It is of the utmost importance to dispose of data securely and properly in order to protect the integrity of the data center as well as personal information stored that is no longer in use.

Different Needs For Tier 1 Data Centers and Tier 4 Data Centers

Spring cleaning for data centers can be highly dependent on the type of data center as the consequences of downtime can vary substantially. Similarly, the consequences of a breach can also vary substantially.  A Tier 4 data center on a military base is a prime example of a data center that would likely need extensive testing and maintenance for optimal security and function.

However, a small municipality might have a Tier 1 data center due to limited needs and limited funds. Downtime for a Tier 1 data center may not be especially detrimental, and off-site servers can be used as a form of redundancy to ensure that critical operations are not interrupted, such as emergency response for citizens.

How to Approach Data Center Spring Cleaning

Work with a team of experts to best approach data center spring cleaning from all necessary angles. Instead of guessing what might be fine for another year, be confident that all systems are fully-functional.  Optimize space, install necessary new components, and maintain existing components to prolong the lifespan of data centers.

Making Sense of Data Hosting Solutions

Data hosting is a serious concern for businesses everywhere. Choosing the right service can hold back your organization or give it a push in the right direction. Without data hosting services adequate to your current needs and adaptable enough to offer you solutions for future growth, the technology your organization relies on will not be up to the challenges posed by a rapidly changing industry.


Today there is a wide range of hosting services available for organizations of all sizes. Each type of data hosting has particular advantages as well as potential drawbacks. Understanding the unique features of each of these hosting options allows you to maximize the advantages of the hosting service you ultimately select. This information will help you zero in on the hosting solution that is the best fit for your organization.


In-House Server


In-house server options are arguably the most straightforward server solutions that an organization can select. All the equipment is purchased, maintained, and upgraded by the organization using it. The server equipment is kept somewhere on site. There is typically a team or department tasked with maintaining the server function and keeping the system running smoothly.


This server option gives you the ultimate flexibility in terms of structure and resource deployment. Members of your organization have the final say with regards to what equipment is selected and how it is taken care of. Security is also under the direct control of the organization. Though this element of control is highly attractive to some businesses, in-house servers require a considerable investment. Physical space has to be dedicated to server storage; improved cooling and ventilation solutions may have to be added to this space to create a climate optimal for computer function. This can be a problem for organizations with limited available space.


Dedicated Hosting Service and Shared Servers


Dedicated hosting service lets clients lease a server that is dedicated to their needs alone. It is not shared with any other client served by the data hosting company. This allows the lease holder to exercise full control over hardware, operating system, and other technical aspects. The hosting company is responsible for physical security, system maintenance, and even IT support services. Though an organization would give up some degree of control, this hosting option offsets many of the necessary investments that an organization would have to make in order to accommodate in-house servers. Though organizations can comparison shop for the most competitive price, clients are typically locked into a contract for a certain period of time.


Shared server solutions have many of the same qualities as dedicated hosting. The difference is that instead of leasing an entire server, the client leases space on a server shared by other clients. Each client is allotted a certain amount of server space which can then be used for website hosting or other data storage.


Managed Dedicated Server


This option is tailored to organizations that do not have the space to house complex server equipment or the means to develop their own server management team. Managed dedicated server hosting services bundle together everything necessary for hosting and then offer these bundled products to their clients. This hosting solution can cost more than other options but makes many specialized services available to clients. Technical services such as the following are offered by many managed dedicated server host companies:


  • Database management
  • Server monitoring
  • Firewall, backup, and recovery
  • Virus and spam protection
  • Software updates
  • Security audits


Virtual Private Server


This is similar to dedicated and shared server hosting except that in this case, a virtual machine is used instead of a physical one. These virtual machines provide many of the same benefits as a physical hosting service, though may not be able to deliver the same kind of performance power since host-end processing has to be shared among numerous virtual private servers. Virtual private servers are quite cost competitive compared to other hosting solutions. This is a popular choice among organizations looking for website hosting services; in fact, many web hosts offer virtual private server space for their clients to use.


Cloud Hosting


Cloud hosting services are a relatively new innovation that has seen divisive opinions regarding its usefulness and ease of application. However, cloud-based solutions have certain characteristics that are an excellent fit for some businesses.


Cloud hosting is made possible by cloud computing. Computers in a cloud configuration work together to provide the services essential for modern business function. This collective effort means that a single machine can fail without compromising the overall function of the cloud; the services can continue uninterrupted while the broken element is addressed. Cloud hosting therefore can provide highly reliable server functions; this has significant advantages in terms of security and stability.


Some businesses are hesitant to adopt cloud hosting solutions for their server needs because this approach is relatively new. There are concerns about the long-term usefulness of this server solution as well as overall data security. Because cloud hosting has received so much industry attention since its introduction, it is fairly easy for business owners to find authoritative analyses of the viability of cloud hosting. Though cloud hosting offers a great deal of flexibility and a number of useful features, the concerns particular to each individual organization have to be considered before selecting this, or any other, data hosting option.


Selecting a hosting solution for your organization is a very important decision and should be made only after a thorough examination of all available options. With a little effort you can narrow down your options to the ones that make the most sense for your organization.
