Thermal Runaway and Hot To Mitigate Your Risk

Thermal Runaway and Hot To Mitigate Your RiskThese are pictures of Valve Regulated Lead Acid (VRLA) batteries that were damaged by excessive heat buildup in the battery causing “Thermal Runaway.” The most typical application for VRLA batteries is in Uninterruptible Power Supplies (UPS) which provide an alternate source of energy, using these batteries, in the event of a power outage. These batteries lost the ability to store current, which causes them to heat up internally. Some batteries became so hot they melted together requiring pry bars and chisels to break the battery free from the tray, rack or cabinet.


What is Thermal RunawayWhat is Thermal Runaway?

Thermal Runaway is an abnormal condition where most of the energy provided by the battery charger results in heat generation, in turn releasing energy that further increases the internal temperature of the battery.  The elevated battery temperature draws more charging current, causing additional heat build-up.  This condition will continue to compound to the point where accelerated dry out and/or melting of the battery will occur and in some extreme cases, cause a fire.

Measures to help prevent Thermal Runaway

-Keep the temperature of the battery environment/room at 77 degrees F as recommended by the battery manufacturer. Every degree above 77 shortens the life of the battery.

-Perform battery replacements on aged or failing batteries according to your service provider’s recommendations, battery manufacturer and industry standards.

-Perform regularly scheduled preventative maintenance on the UPS and batteries to test impedance, resistance and voltage.As a UPS and battery service provider, we encourage customers to follow these recommendations to ensure the continued integrity and reliability of their backup power systems.

As a UPS and battery service provider, we encourage customers to follow these recommendations to ensure the continued integrity and reliability of their backup power systems.

Prepare For A Real-World Power Outage With Roll Over Testing

Modern companies all over the world that rely on large scale technology and complex support systems to maintain the operation of critical loads must have a way to prevent anything that might lead to downtime. For the majority of these businesses, downtime is simply not an option and the negative effects suffered by business profits and the productivity of the staff during downtime must be avoided at all costs. The best way to avoid downtime and its negative effects is with a carefully planned and implemented routine for prevention. An integral part of this plan is data center testing, including the vital component of data center roll over testing.

Data CenterThere are several important components of data center testing in addition to data center roll over testing. These components include four important tests. Infrared thermography refers to scanning the electrical system with a specialized camera in order to catch any spikes or drops in temperature. Load bank testing refers to the part of testing which evaluates the fuel systems, the exhaust and the engine cooling systems. UPS acceptance testing is the third test and is occasionally provided in order to ensure that the UPS system is running according the specifications set forth by the manufacturer. Finally, facility roll over testing will be performed in order to verify that during a power outage, all of the data center’s emergency back-up systems will be functional.

The role of data center roll over testing among the other components of testing becomes clear when considering the possibility for a real-world power outage. Extreme temperatures, downed power lines, blown transformers or digging for construction can all create a situation where outside power sources are affected. These circumstances may be anticipated by a business, but can’t be predicted. In order to be sure that critical buss loads aren’t affected by a real-world power loss, the data center back-up systems must be able to instantly be in effect as a power outage occurs. For all non-essential loads, the back-up power systems should be providing a power stream within seconds of the power outage. The roll over testing will ensure that the alternate power supply will be immediately and fully responsive. Another important aspect of data center roll over testing is to be sure that the facility is able to correctly re-establish connections with the original source of utility power.

Data CenterData centers are commonly full of complexity and interrelated systems. A great deal of thought, creativity, cooperation and capital has been focused on the development of the internal operations of data centers and integration between the data centers and other facilities. The entire system must be able to work as an independent, but integrated whole. In order to ensure that this goal is accomplished, each important component of testing must be included in routine maintenance and prevention programs.  Instead of putting productivity at risk, regularly scheduled testing and other risk management practices must be implemented.

Data center roll over testing is an important preventative component of the testing routinely performed by data centers and businesses with other large electronic requirements. Before your business or center is affected by a real-world power outage, schedule facility roll over testing and train your employees in the procedures that will accompany the roll over.

Properly Installing Power Distribution Units For Future Growth

Data CenterToday’s data centers are vastly different from ten, five, and even one year ago, and the proper installation of power distribution units (PDUs) is an exercise in both addressing your immediate needs while planning properly for the future growth of the center. Installed correctly, these units can distribute power appropriately throughout all the components within a facility. This article will address some of the pitfalls common in PDU installation, and how to address them for optimal data center performance.

Changing Data Center Power Needs

A few years ago, equipment in data centers was larger, bulkier, and more spread out, and as such, many companies did not even use power distribution units. Now, with all the virtualization strategies and blade servers, a large number of servers can be densely packed into a smaller space. While this is beneficial from the standpoint of requiring less real estate to house the same amount of equipment, it also means that you will need a more comprehensive strategy for distributing power evenly throughout the center.

data center design There are two types of PDUs, floor-mounted and rack-mounted. Floor units tend to be fewer and farther between, located around the edge of the data center to feed power to the racks. Rack-mounted PDUs would then take the power and feed it to the computers, networking equipment, and servers.

Some Pitfalls In PDU Installation

One of the most common mistakes made when planning and installing PDUs is to build with today in mind, and expect to add on in the future with the exact same design. At first glance, this may seem like a sound strategy: save money right now by building for only what you need, and build out in more of a modular design as your needs grow. The problem with this strategy is that in an ever-changing IT world, the next generation of servers will probably not look like the ones you have today. As a result, the power needs of tomorrow’s servers will be much different, and using old PDU technology to build on in the future can result in less efficiency and higher overall costs.

Another mistake often made by companies is to try and go with the lowest cost PDUs. Building a data center requires a significant up-front investment, so it can be tempting to save money wherever possible. Keep in mind, though, that shaving costs today by installing PDUs incapable of meeting your growing center can add up in the future when you have to add more elements to your system and reconfigure or install new PDUs to meet changing needs.

Finally, many companies use a measure of average watts per square foot to determine their overall data center power needs, then arrange the servers in a way that creates uneven power consumption. This can complicate PDU installation, creating problems and bottlenecks in power distribution unless the center is carefully planned to avoid uneven power usage scenarios.

The need for efficient PDU installations is increasing every year, and without a proper plan for your changing power needs, your data center can quickly become obsolete and require significant additional costs to bring it up to speed. Companies that are willing to invest time and effort into PDUs that are built for future expansion can realize significant long-term savings and be ready for whatever the world of IT brings.

Portable Cooling Units Keep The Data Center From Heating Up

Portable CoolingThe costs of lost data or computer downtime can be catastrophic for a business. Much of this loss may be associated with overheating, or, in other words, the loss of appropriate data center cooling. As businesses and even individual computer users within their own homes have found, overheating computers are a growing problem. The more that society relies upon technology and computers for the movement, sharing and saving of data, the harder hard drives and servers must work. When those systems aren’t carefully monitored, overheating and other problematic circumstances can occur and may lead to substantial losses.

Maintaining your data center cooling is a constant concern. As the data center and its operations grow, the needs for appropriate cooling equipment will also grow. Incorporating portable cooling units specifically designed for use in data centers is a convenient way to keep the cooling system simple. With the complexity that is an integral part of server rooms and data centers, simplicity is part of the cooling system can be a relief for anyone who is involved in operations, maintenance or repairs. As the data center grows, adding portable cooling units is an affordable and simple method of increasing the cooling capacity of the data center’s cooling system.

Portable CoolingToo much heat is a consistent problem in data centers and related facilities. Even though there are already intricate systems and complex equipment put into place for managing the cooling of the center, spot cooling or precision cooling can be managed with portable cooling units. Data center cooling is already an expensive component of data center systems and making adjustments with affordable portable air conditioning units is a much cheaper option than implementing additional permanent pieces of equipment. Furthermore, the fewer pieces of permanent equipment there are throughout the cooling systems, the less the potential for problems and malfunctions to occur.

Modern servers have dramatically gotten smaller over the last several years. Instead of requiring an entire building, the server may fit smoothing into the space generally set aside for a closet. However, the server, still doing the work of the larger machines, is generating a great deal of heat in that small space. The tightly packed spaces housing servers become very difficult places to control heat and maintain the appropriate temperatures. Even during the winter, keeping the space cool is a problem, but during the hot months of the summer, the normal capacity of the data center cooling system isn’t enough to keep the center’s temperatures down appropriately. Portable cooling units can provide the extra boost of cooling power and will fit into many small spaces.

Instead of considering the portable units a temporary part of your data center cooling system, consider them to be a convenient and movable source of emergency cooling, maintenance cooling, spot cooling or seasonal cooling. At times, the portable cooling unit can provide a higher level of efficiency than a permanent unit near the same capacity. This translates into savings in more than one way and every business can appreciate multiple ways to save on cooling, maintenance and other business related costs. Keep business in your data center from over-heating with a portable cooling unit.

UPS Maintenance For Mission Critical Systems

Keeping Mission-Critical Systems Running With Reliable UPS Maintenance

In your data center you have all the proper planning in place to account for emergencies like a power failure, with a backup uninterruptible power supply (UPS) system to ensure that your mission-critical systems are always running—but is your system ready? If you are not performing regular UPS maintenance, especially on the battery, it may not be ready to go when you need it. Here are a few things you should be doing on a consistent basis to ensure that your UPS system, especially the battery, is ready to power your vital systems when the power goes out.data center maintenance

First, when you install the system, make sure that the UPS can maintain constant contact with the electrical ground. As you are performing your regular UPS maintenance, double-check to see that this is always the case. In addition, it’s important not to overload the UPS, and if you see potential problems during your routine maintenance, remove it from your system until you can repair or replace it. These small steps can save you a lot of trouble down the road.

Inside the UPS there is a battery, which is the most likely part of the system to fail, and in the long-term you will likely need to replace the battery to keep your system running. The system will come equipped with a battery sensor that should alert you when the battery is degrading, but if the sensors are not properly working, the battery can easily fail without you even knowing it. In that case, you won’t find out that you need a new battery until you need the UPS and it’s not working. To prevent this from happening, part of your UPS maintenance plan should include testing the battery sensors at regular intervals. Doing this approximately every six months should be sufficient.

Some of the things that will drain your UPS battery more quickly include exposure to extreme hot or cold temperatures or high humidity, and frequent power outages that tax the UPS. While there is not much you can do about the latter, to prevent the former, your UPS maintenance plan should include regular inspection of the data center facilities to ensure that the environment is optimal for your system.


When you do have to replace your battery, it is important to recalibrate the entire system, including the battery sensors and the dwell-time calibration. The process for recalibration will differ depending on your software, but it’s an important step to remember when you install a new battery.

If you are not sure you can perform these types of checks on your own, you may want to consider purchasing a UPS that includes a service contract. If you have a low-end unit, the cost of a service contract may outweigh the cost of simply replacing your entire unit if something goes wrong, but for extensive data centers that require multiple high-end UPS systems, service contracts can be beneficial, especially if the alternative is significant downtime following unit failure, while you are trying to get it back up.

The wrong time to realize that your UPS is not running properly is when you need the backup power supply. Instead of being left with downtime and lost productivity, be sure you have a proper UPS maintenance plan for your center.

The Importance Of Maintaining Your Data Center Equipment

data center maintenanceYour data center is an important investment in your business, housing all of the equipment and information that keeps your company running from day to day. When you build a new datacenter, it may seem like the project is complete once the construction is over, but ongoing datacenter maintenance for the physical equipment is just as important as the initial build.

Inside your datacenter there are several different physical equipment components—the computers and servers, the racks, furniture, cooling systems, and flooring. All of this equipment is important to include in your regular datacenter maintenance plan. Without regular check-ups in all these areas, your server room can quickly become damaged, and even fail.

First, inspect your datacenter from the ground up. It’s a good idea to regularly inspect the flooring and make it part of your “equipment” maintenance plan, because even if it doesn’t seem like flooring fits in the same category as things like racks and servers, wear and tear on the floor can quickly become a problem for the rest of the things in your datacenter. Check for signs of chipped scratched, or worn areas, and also make sure to regularly clean it to remove dust, rust, and other problems. If you have a cooling system that is tied to the floor (for example, a raised floor that allows proper cooling to take place), inspect that system regularly and make sure that it is still working properly, especially after you have moved items around.

Next, check for dust. Regularly sweeping the floors to keep dust from building up, and also dusting the racks and the equipment, is essential for the long-term viability of the equipment in your datacenter. If your datacenter maintenance plan doesn’t include dusting, add it right away. Also, if your center is off-site and it’s difficult for your IT people to get there regularly, consider hiring a cleaning company to regularly dust and vacuum the entire room.

The equipment racks are not only subject to dust, but also to general wear and tear. Your datacenter maintenance should also include inspection of all racks to be sure there are no loose bolts, cracking, rust, or other damage. If you can spot these things early, you will be able to fix it before the rack collapses and damages all the servers and other equipment in the area. In addition, pay attention to how hot the area around each rack is to be sure all the areas are getting adequate cooling. If it is particularly hot in certain areas, you may need to introduce more cooling systems, or move the racks around until they are properly spaced for adequate cooling.

data center maintenanceFinally, check around for stray furniture. Over time you will probably accumulate pieces of furniture—a small table here, a few chairs over there—that people use when they are in the computer room. In order to properly maintain your datacenter, you want to minimize these items and definitely keep them out of the main walkways. This is good practice to ensure a safe environment and avoid workplace accidents or fire hazards as well.

While you may not have thought about all these things as part of your datacenter maintenance plan to keep equipment running in top form, these small details are just as important as the big equipment.

Keep Your UPS Performance Up With Scheduled Maintenance

Keep Your UPS Performance Up With Scheduled MaintenanceYour uninterpretable power supply or UPS is a series of batteries whose function it is to maintain the flow of power to critical equipments within your data center that are unable to withstand power interruption. Your UPS is also able to shield your data center equipment from blackouts, brownouts, voltage spikes and frequency variations as well as any transient disturbances in incoming power. A majority of your equipment requires uninterruptible power to function properly, which is why your UPS is so critical. Breaks in utility power supply are inevitable, and most equipment will shut down after a few cycles of disruption to their power source. Consequently, your UPS is an essential component of your data center system.

Minimizing disruptions to the power source starts during the power system’s design phase. A reliable power system depends on quality equipment and reliable design. A facility’s UPS should be designed to protect critical and high-tech equipment and to facilitate planned power outages so technicians can perform maintenance.

Preventative UPS maintenance should be a regular occurrence for anyone with a data center. Routine cleaning, testing, and inspection will reduce incidences of downtime and increase the longevity of data center equipment. To achieve optimum results, preventative maintenance should be performed at regularly scheduled intervals. For example, a standard UPS maintenance service plans might include the following maintenance schedule.

data center designVisual inspections of data center equipment could occur on a quarterly basis. If your data center’s backup power system includes a generator, it might be tested at quarterly visits as well. Semiannual maintenance would likely include backup generator testing and checking for liquid contamination effecting capacitors or batteries. At these same visits, UPS equipment and enclosures would be thoroughly vacuumed and cleaned. HVAC equipment would be checked at these visits as well to ensure temperature and humidity are at appropriate levels.

Annual and Biannual inspections should also be incorporated into your UPS maintenance schedule. Annual visits would include thermal scans on electrical connections. These scans verify that connections are tight and are not producing heat. An operational test of the entire system is also appropriate at an annual inspection. Biannual inspections include the testing of UPS transfer switches along with maintenance bypasses and circuit breakers.

This is just one example of a possible UPS maintenance schedule, and is neither exhaustive nor wholly comprehensive in scope. Nevertheless, it gives you a clear sense of the thorough over site and care that your UPS would undergo with such a service plan in place. You can easily imagine how malfunctions and needed repairs would be detected in a timely manner. Many potential problems would be averted completely, as UPS maintenance is highly preventative. The incidence of downtime would be markedly diminished and efficiency would remain at peak levels.

The mere existence of an uninterruptible power supply does not ensure protection from power surges or failures. If you want to be able to rely on your UPS, you must be sure to provide it with routine oversight and care. Regular testing of the UPS will protect data center and institutional equipment from power fluctuations and distortions, and ensure it is operating a peak potential. In so doing, critical systems will be protected and be enabled to operate reliably as well.

UPS Maintenance Plan Recommended For Optimum Performance

UPS Maintenance Plan Recommended For Optimum PerformanceAny quality UPS service plan will unequivocally include a preventative maintenance plan. UPS maintenance plans are imperative to proper and reliable UPS function. No matter how expertly your UPS was designed or how painstakingly is was manufactured; it will be vulnerable to failure for any variety of reasons. There are a wide range of factors that can cause a UPS to fail, therefore ongoing UPS maintenance plans are essential to protect your data center from events such as power surges or outages.

A significant percentage of UPS failure is attributed to batteries that have failed or degraded. The types of batteries generally used in UPS products have proven sensitive to heat, so overheating can cause a reduction in available power. Every time lead acid batteries are discharged, their capacity is permanently reduced and their operating lifespan is shortened. Quality UPS maintenance plans will include battery checks and facilitate needed replacements.

Fans are essential to keeping uninterruptible power supplies cool. While fans are simple and require little energy, the do eventually wear out or experience failures. Something as simple as a fan failure could easily go unnoticed. Fan inspections are also part of quality UPS maintenance plans. If fans have succumb due to electrical or mechanical problems, your UPS maintenance plan technicians will identify the problem and efficiently repair or replace fans that are so afflicted.

UPS Maintenance Plan Recommended For Optimum PerformanceThe UPS incorporated into your datacenter has many electrolytic capacitors that work in concert to smooth out voltage and filter fluctuations that could threaten your datacenter. Any time one or more of these capacitors fails, the remainder must take up the slack. This increased work load shortens the functional life of each capacitor that is so affected. If too many capacitors fail without being replaced, it can leave your UPS unable to safeguard downstream loads. This is yet another reason that UPS maintenance plans are so highly recommended.

Every UPS has a filter/rectifier side. Fatal damage can occur at these sites due to sudden power surges. Comprehensive UPS maintenance plans are preventative in nature and are highly recommended as your best defense against threatening power surges. UPS equipment that is properly and thoroughly cleaned, evaluated, calibrated, and tested on a regular basis is at a markedly reduced risk of interruption or failure. This means your likelihood of company exposure to IT downtime is greatly reduced, preserving your productivity as well as your bottom line.

When selecting a UPS service provider to perform your semiannual maintenance, look for a provider that offers a number of services in conjunction with your semiannual maintenance. They will have a team of experienced field technicians who participate in ongoing trainings and certifications. The focus of a strong UPS service provider will be on long-term solutions rather than just short-term fixes. Remote monitoring services will allow service providers to monitor your UPS between regularly scheduled maintenance visits. Finally, upgrades and modifications will be readily accommodated as needed.

Semi-annual UPS maintenance from a high quality service provider is highly recommended. Companies that follow this recommendation have significantly fewer failures than those who do not take advantage of regular UPS maintenance. What’s more, preventative maintenance for your UPS will not only reduce your incidence of downtime, it will also maximize your UPS performance. As a result, UPS maintenance plans are not only highly recommended, but cost-effective as well.

Finding A Quality Construction Team For Your Next Datacenter Project

data center maintenanceWhen you are preparing for your next datacenter construction project, whether it is your first time or you have built datacenters before, you probably know that the construction team you choose can have a big impact on the outcome of the project. In fact, the construction team you choose is one of the biggest factors that determine whether your building project is a success, completed on time and within budget, or whether it’s a financial or operational disaster. To hire a good construction team, consider these factors.

Find a trustworthy company. Your data center is going to house some of the most important—and probably some of the most expensive—pieces of equipment in your entire business. Not only is the equipment very specialized and imperative to keep running in tip-top shape, but the volume of sensitive data that may be contained in the servers you install in your data center is equally valuable.

If you cannot trust the datacenter construction team to be strict about the quality of the data center, there are many things that can go wrong. The building itself must be high quality to ensure that it does not fall apart. In addition, if the construction team is not paying attention to detail, you may end up with faulty wiring, an inadequate cooling system, or some other problem that can damage the equipment inside.

Be firm about deadlines. Choosing a company that can complete your project in a timely manner is a worthwhile investment when you are preparing for your datacenter construction. Delays in the timeline of a project can be frustrating, not only because they delay the time before you can use your data center to its fullest potential, but also because they can be very costly. Check the track record of the construction crew you are hiring to find out if they consistently complete projects on time, or if they have a habit of cost and time overruns.


Finding A Quality Construction TeamSave money with a quality construction crew. Because datacenter construction projects tend to be costly ventures for any business, it is often difficult to convince upper management that it’s a necessity. In some cases, even if management signs off on the project, they want to find the least expensive option for doing it. It is always a good idea to shop around and find an affordable company, but keep in mind that just because a company is charging the lowest price does not mean they are the best deal. Be sure that with the price you pay you are getting the highest quality construction, otherwise you may end up having to pay even more later to fix mistakes from low-quality work.

Get it done right the first time. Check out each company’s track record to make sure that their prior clients are satisfied and received quality, accurate work. Companies that can complete your project to your exact specifications the first time will always save you money and time over datacenter construction companies that do it wrong and have to keep coming back to fix it.

Constructing a great datacenter is an essential part of your business, and finding the right construction crew to build it just the way you need it is equally important. Using these tips, you can find the best construction team and be on your way to a new datacenter.
