What Changes Are in Store for Data Centers With Lithium-ion Batteries?

UPS Maintenance

Lithium-ion (Li-ion) batteries offer significant benefits over the traditional valve-regulated lead-acid batteries (VRLA) used in data centers. For smaller centers, like those in medium to small businesses, the change could be very dramatic. Here are six reasons your organization should consider making the switch.

Less Space Required

VRLA batteries require a lot of space. Some companies even build separate battery rooms to house the power system. Li-ion batteries can reduce the space needed by about two-thirds. Think about having more IT space to grow your network.

Cooling Costs Reduction

The equipment in a data center can tolerate higher temperatures than the VRLA battery. If you are raising the temperature in your data center to reduce your costs, it’s probably that the VRLA batteries in the same room will need to be replaced quicker because those batteries cannot tolerate the heat. Li-ion batteries are better equipped to be in the same room as your other equipment without deteriorating as quick as their VRLA equivalent.

Scalability for Growth

Many companies today are using modules to grow their system over time. Li-ion batteries are much more scalable and adaptable into the architecture that is being designed for data centers. Instead of worrying about where your organization needs to house more equipment and batteries to expand, the Li-ion batteries provide more options. Avoid costly remodeling when your business is ready to add on to your data center.

Better Performance

Li-ion batteries last much longer than VRLA batteries, almost twice as long. Because the Li-ion batteries come with better monitoring systems, it’s easier for an IT team to measure the health of the battery and know when it needs to be replaced. It’s much like the battery monitoring system of your smartphone, while the VRLA is similar to your car battery. You never know when it might fail, leaving you stranded. Less maintenance and concern come with better performance. This lets your staff focus concern on higher priority ticket items.

Environmentally Friendly

By reducing the cooling costs and space requirements of a network, it adds to the eco-friendly statistics of your organization which cannot be overlooked in today’s business environments. Clients are looking for businesses which do care about their energy use and power consumption Li-ion batteries offer some unique features to help reduce the carbon footprint of your business.

Less Replacement Costs

VRLA batteries are often replaced every five to six years, even though it should have a life of about 10 years. This is because of the unpredictability of the battery. An Li-ion battery lasts much longer than 10 years, which reduces battery replacement costs.

The Power Rating of a Rack PDU Is Not Always the Load Capacity

Advanced PDU

Even if you aren’t an IT specialist, you probably understand circuit breakers and electricity. Each breaker is designed to handle a specific power load. When that capacity is overloaded, the breaker trips and shuts off the electricity to the circuit. The same thing happens with a rack power distribution unit (PDU) that distributes the electrical power to your computers and network. By understanding how the power rating differs from the load capacity, your organization can prevent overloading the PDUs that keep your computers operating efficiently.

Power Rating

One issue in power ratings when it comes to PDUs is that North America and Europe label the capacity differently. Outside of North America, the circuits are simply labeled as the rated capacity; you may see one that says 16A or 32A. In North America, manufacturers label the units with their maximum load capacity.

Why is this a problem? It’s because the PDU is actually designed to be loaded at only 80 percent of their capacity. This is referred to as a derated value or the load capacity. Thus, if you have a 20A PDU, it’s actual load capacity is only 16A. While the PDU may certainly carry 20A for a limited time, eventually it will trip and the system will go down.

Simplify the Network

Although there are formulas which let your IT manager calculate the load capacity and voltage that is appropriate for each section of the PDU, there is a much easier method to keep your system balanced. An intelligent PDU takes the guesswork and math out of the capacity equation.

In today’s business world, your network and computers need to be fully functional and operational when you need them to be. Keeping the power load evenly distributed ensures that your IT department doesn’t go down when you need it most. It also helps your organization use electricity more efficiently to save money. What business couldn’t use more time and money?

Intelligent PDUs also provide more benefits such as metering that alerts the team to potential problems. Your IT department has access to logs which help them see erratic power consumption or ghost servers. By understanding that the power rating is not necessarily the load capacity, you can more evenly distribute power and take steps to grow your system as needed. Instead of buying more equipment than you need or not having enough, with intelligent PDUs, a business can operate with purpose. Learn how an intelligent PDU would upgrade the network in your organization.

Benefits of Intelligent Metering With a Rack PDU


Having multiple power units can make your IT structure more efficient, but only when you know how much energy is being used by each track. You have to manage your power capacity by tracking energy use. It’s not only good for your system, but it’s better for the environment when you balance how much power each unit is putting out.

Intelligent rack power distribution units (iPDU) have many added features over a non-intelligent PDU that let you track the voltage, current, power, and energy usage within your own IT infrastructure. Metering helps your organization become more efficient and increase network availability. This option is available at the inlet, outlet, and PDU level. Here are the reasons to choose an intelligent PDU that offers metering.

1. Inlet Metering – This feature lets users see power usage and capacity within each rack to provision equipment more effectively. Your IT administrators can prevent overloading circuits and calculate the power usage effectiveness to boost your system’s efficiency.

2. Outlet Metering – With this feature, you can also see power usage and capacity at the rack, assisting in what the inlet metering provides, but outlet metering helps your team find underutilized servers and to allocate costs usage to specific customers. It also helps identify ghost servers and compare your IT efficiency.

3. Rack PDU Branch Circuit Metering – Practically every system runs the risk of being overloaded, which leads to tripping. When your team is adding more circuits, this feature prevents circuits from being heavily loaded. There is less chance of experiencing downtime from tripping a breaker. If your organization uses high-power consumption components, this helps the data center manager keep your entire system balanced. It sends an alert based on the threshold your team sets up if the circuit is becoming overloaded.

4. Circuit Breaker Monitoring – When you have multiple units, it can be difficult to quickly find a circuit breaker that has tripped. Metering monitors this event to allow your team to quickly reset the breaker and get back to business.

Using an iPDU helps your business grow more efficiently, because you can add units and ensure you won’t overload your current system. You have the knowledge to keep up with your energy needs. Today’s businesses cannot afford to use energy inefficiently. It increases your utility costs, and it keeps your organization from being eco-friendly, which it important to today’s consumers. Take charge of your IT system with intelligent rack power distribution units that give you more options in energy consumption. Use the resources of the planet wisely and save money and time in your company.

Cloud Connectivity


Does Your Business Have a Strategy for Cloud Connectivity?

 Over the next few years, cloud infrastructure spending among businesses is expected to take up more of your IT budget. In 2014, cloud expenditures accounted for about five percent of the IT budget. In 2018, it’s expected to jump to 11 percent. The cloud is not going away, and it’s important for your business to take steps to create a strategy for your organization now.

Do You Really Need Cloud Connectivity?

Many businesses have invested in on-premise cloud infrastructures, so you may be wondering if you need anything more. One of the big issues with an on-site system is that it requires a great deal of administration and resources. Then you have the public cloud systems. There are some real concerns about security when using a public connection. An enterprise cloud connection combines secure protocols to integrate your storage and usage components to build your business. When you have a strategy in place to utilize both types of cloud storage, it lets your organization grow and keep your computer system to scale.

Types ofPublic Enterprise Cloud Connectivity

Amazon Web Services (AWS) is one option that gives you more flexibility in your public and private networks. With their Direct Connect option, you can establish a dedicated connection between your network and the AWS servers. You have more options because it integrates with all of the AWS cloud options. You have a lot of options when it comes to reconfiguring the networks to meet your growing business changes.

Microsoft Azure ExpressRoute is very similar to AWS, but it doesn’t use the public internet as a connection. Your business gets more reliability and security between the public cloud and your own network. It extends your system without requiring more resources and equipment from your organization. You also have the option to build your own ecosystem for different applications. ExpressRoute lets you connect with other Microsoft services outside of Azure.

Leveraging Your Options

Both Direct Connect and ExpressRoute offer significant cost benefits over creating your own private cloud storage. As more businesses become both global and mobile, give your organization the strength to grow your own data infrastructure with an Enterprise cloud connectivity strategy that helps your data center grow as your organization grows. If you’ve made the investment in an on-site system, you don’t need to reinvent the wheel to have more options with the cloud. Build on what you have with the technology available to you and create reliable connections that have the speed you need to get business done.

Rack PDU Power Rating vs. Load Capacity


Understanding Power Rating and Load Capacity for PDUs

A PDU (Power Distribution Unit) is an electrical component that distributes power to multiple devices in computer data centers and high energy use areas.Able to handle more energy than ordinary power strips, PDUs can easily power multiple equipment racks. However, choosing the right PDU requires understanding power ratings and load capacity, as well as knowing the power requirements necessary to run the specific devices.

What Are Power Ratings?

A power rating is the amount of electrical power needed to operate a specific device. Ratings are expressed in amps, volts and watts to reflect power usage requirements. Amps, or amperes, reflect the actual electrical current coming through the power lines. Power distribution units are designed to support a specific number of amps or amount of electrical currents. Volts refer to the pressure that moves the amps along a specified path (cable, cord or line). Standard electrical plugs in the United States have voltage ratings of 110 and 120, which is the maximum amount of power they can handle. Watts represent the actual electrical power that a network switch, server or other device uses.

What Is Load Capacity?

Load capacity refers to the maximum amount of power required to operate a specific device. In a data center where a power distribution unit supports an entire rack of equipment, the PDU must provide the minimum amount of power needed to support the rack’s load. To avoid circuit overload and fire risk, the load capacity for circuits in North America is 80 percent of that circuit’s maximum capacity. For example, a 15 amp circuit has a maximum load capacity of 12 amps. The 80 percent value is the load capacity.

Selecting a PDU

When choosing a rack power distribution unit, there are several key elements to keep in mind:

  • Type and number of outlets needed on the PDU and types of plugs on devices.
  • Power rating and power requirement of devices to be supported by the PDU.
  • Infrastructure voltage (in North America 120V and 208V single phase, 208V three phase or 400V three phase).
  • Determine circuits, phase and amperage needed to power the rack of equipment.
  • Decide if switching and metering is required.


Review PDU installation options

Establish what, if any, additional features are needed.

The most vital part of choosing a PDU for a data center is understanding power rating and load capacity. It could mean the difference between overloaded circuits and down time and increased productivity and profits.

What DCIM Tools? You Mean Spreadsheets and Tape Measure?


DCIM Tools: Beyond Spreadsheets and Tape Measure

Data centers aretraditionally made up of two distinct components: IT and facilities. IT is responsiblefor the servers and devices located in the racks, as well as the applications installed on those devices and the management of the devices themselves. Facilities is responsible for physical security, environment, power, lighting, cabling, plumbing and other site management concerns. In the past, each group worked independently of the other and utilized separate software systems to manage their areas. However, that is no longer the case. DCIM tools are designed to integrate IT and facilities management with one software solution that incorporates asset and inventory management, operations management and power configuration and monitoring.

Asset and Inventory Management

The asset and inventory management component oversees every physical piece in the center, as well as provides the following tools to help effectively utilize information:

  • Workflow management
  • Change planning
  • Capacity planning
  • Power consumption and efficiency
  • Power planning
  • Energy cost
  • Heating, cooling and ventilation planning
  • Performance over time


By providing a long-term view of data center resources and performance, this feature will be extremely useful in planning future power, space and asset needs.

Operations and Management

This DCIM tool allows for the creation of live statistics and live monitoring of every device in the center, in particular, the following:

  • Power
  • Cooling
  • Security
  • Environment


These features, along with a live map of equipment placement in the data center, alarm and threshold management, provide a convenient and effective means of troubleshooting a multitude of different problems that can ultimately minimize downtime.

Power Configuration and Monitoring

With power configuration and monitoring tools, data center managers are able to monitor and report on the center’s complete power path from how the power comes into the center to how it is distributed to its current status. Constant, real-time monitoring of the power path means that failure along any point of the path can be more easily located and quickly repaired. Immediate identification of power issues reduces the risk to other devices along that specific path. Real-time problem identification leads to real-time problem mitigation.

All of these components and the tools within them are able to communicate between one another. This allows data to be analyzed on many levels and in many configurations, which ultimately leads to better data center management from both an IT and a facilities perspective. The ability to custom design Data Center Infrastructure Management solutions means systems can be created to meet the specific needs of individual data centers.

The UPS Debate: A Conversation on High Efficiency, Multi-Mode UPSs


High Efficiency, Multi-Mode UPSs

Uninterruptible power supplies (UPS) are designed to protect against power surges and to keep data center equipment running long enough to power down safely during electrical outages. With the normal expense of powering data centers and the increased cost in dollars and data that can be caused by downtime due to power failure, high efficiency, multi-mode UPSs are fast becoming standard equipment in computer data centers.

How Does Multi-Mode Work?

A multi-mode UPS is capable of switching between two modes of operation. Premium efficiency mode, also called eco-mode, provides superior operation efficiency while double conversion mode provides superior power protection. Multi-mode UPSs can switch between these two modes in a matter of milliseconds to compensate for power deviations and anomalies. In fact, most UPSs have transfer speeds of less than eight milliseconds and, in many cases, as few as two milliseconds, so as not to exceed the tolerance levels of data center equipment. Multi-mode UPSs have the ability to deliver continual computer grade power while reducing both energy costs and environmental impact.

What Are the Benefits of Multi-mode UPS?

Uninterruptable power supplies come in the form of single-conversion systems, double-conversion systems and multi-mode systems. By incorporating the features of both single and double conversion, multi-mode UPS systems are able to offer the following three major benefits:

  • Maximize critical load protection without sacrificing operating efficiency.
  • Extended parts life of one to two years minimum.
  • Output fault mitigation immediately handled by upstream overcurrent protection.


The ability to switch between power protection and operating efficiency modes increases the energyefficiency of multi-mode UPSs to 98 or 99 percent. This automatic switching capability also reduces the load on heating, ventilation and air condition systems. Decreased energy consumption plus decreased load on HVAC systems equals decreased total cost of ownership.

How to Choose the Right High Efficiency, Multi-Mode UPS

As with most products, not all UPS systems are created equally. When selecting the multi-mode UPS for your data center needs,Pedro Robredo at Eaton suggests asking these five questions:

  1. Does the UPS sacrifice protection to gain high efficiency?
  2. How does the UPS achieve its high efficiency?
  3. How efficient is the UPS when lightly loaded?
  4. How quickly does the UPS detect and respond to power events?
  5. What extras does the UPS offer for maximum protection?


The answers to these questions and an understanding of UPS will better equip managers to select the right high efficiency, multi-mode UPS system for their data centers.

Which Infrastructure Convergence Is Best for You?

Infrastructure convergence is the grouping of several IT components into one computer package. With several possible components (servers, networking equipment, data storage centers, and software), there are also several different types of convergence. Take a look at the three current options. With more information, you may be better able to determine which option is best for your situation.

Unified Architecture

This convergence method is based on the traditional rack-mounted server situation. However, with a move toward virtualization, the modern blade-and-chassis environment is markedly different. Users are now able to tie directly into fabric interconnects. Users can create their own hardware and service profiles. These powerful systems maintain their agility but come with a hefty price tag. A high-end architecture, although expensive, might be the best option for large service providers with many different resources and hundreds or thousands of racks.

Converged Infrastructure

This type of grouping is a node-based unit with both storage and computing equipment in one location, sometimes called an appliance. When consumers want to expand, they simply add another node. This offers a lot of versatility and some financial savings as big workloads can be merged into smaller infrastructure nodes. Who would benefit the most from this type of setup? Users are often mid-sized organizations looking for a way to offload VDI and move toward a price-conscious option. Of course, the converged infrastructure is easy to upgrade, so downsizing initially won’t prevent an organization from growing in the future.

Hyper-Converged Infrastructures

While the other two groupings rely heavily on the hardware, this infrastructure converges all of the components of data processing in one single computer layer. The benefits are simplified storage, easier networking, and an abstract, software-controlled process. The hardware stack can be custom built or modified without fear of damaging the infrastructure. This could lead naturally to some important financial savings. A vital part of this hyper-converged virtual appliance is the hypervisor. The hypervisor allows control of resources, API integration, and the convergence of compute, storage, and networking all in one device. Users of this system may be those organizations that are growing rapidly with the need for quick changes, usage growth, and new additions.

Focus on an Agile Infrastructure

Is it possible that hardware stacks will go the way of the floppy disk? As this hardware becomes condensed and abstracted, it may be possible. If data, VMs, and applications are able to move quickly and easily from data centers to the cloud and among many users, the future of data centers will continue to evolve. As businesses rely more and more on data centers, the drive for change is sure to remain constant.
