Reminiscing Past and Predicting Future Data Center Trends

By: Kevin O’Brien, President, Mission Critical Construction Services, EEC


After nearly 30 years in the data center industry, it’s interesting to see how the advent of new technologies and current events have impacted the data center’s evolution and shaped the structures we see all over the world today.  Here’s a blast from the past and a look into the future of data center facilities:

The 1980s and 1990s

I began my career in the data center industry in the ‘80s as a Facilities Manager for a large financial services company headquartered in New York.  At this time, it was commonplace that data center facilities be located within the same building as trading and office spaces.

1988 marked the year that we began construction of our very first remote site facility outside of New York, solely dedicated to data and telecommunications.  Prior to our data center, the site was home to an ITT communication HUB in New Jersey that functioned as the headquarters for the “Hot Line” link between Washington, DC and Moscow.  During this time, the majority of functions were analog and having the remote site gave us a way to increase the redundancy and reliability of electrical and mechanical systems.  Back then there was no Tier certification system, but through this we were able to reach what is now considered a Tier II standard for electrical systems and additionally achieved the equivalent of 2N on the UPS.  In the late ‘80s, load-in data centers ranged from a mere 35-50 watt maximum per square foot.

To meet the rise in demand for fiber and reliable computers, many companies began choosing remote sites during the ‘90s.  In 1989, coming as no surprise to industry professionals, the 7×24 exchange started publishing articles sharing the common experience on seeking ways to improve overall reliability throughout mission-critical facilities.  Stemming from this in the early ‘90s, the Uptime Institute was created, bringing with it the widely used Tier certifications.

The Dotcom Era

The next noteworthy paradigm shift occurred during the dotcom boom.  To meet exploding demand, companies began constructing data centers containing more than 100,000 square feet filled with racks equating to roughly 50-75 watts per square foot at full capacity.  Companies were able to build anywhere in the world thanks to the rapid proliferation of fiber as well as the economic upswing.  With unbridled optimism, companies overbuilt only to watch the stock market plummet following the events of September 11.  However, after a few years, the predication of demand for servers was finally brought to fruition.

Following the dotcom collapse, the Sarbanes Oxley (SOX) law was developed in 2002, requiring data centers that supported financial trading to locate their facilities within a designated number of fiber miles from Wall Street.  In addition to its proximity standards, SOX also required the construction of a separate, synchronous data center for redundancy, resulting in construction growth throughout New Jersey.  By this point, sites began to encroach upon the 100 watt per square foot barrier, while many reached Tier III & IV status.  Square footage and costs continued to rise as additional space was needed to support more robust infrastructure.

Demand for Density and Redundancy

Alongside the need for greater density and redundancy, this era saw the development of the building square foot ratio of raised floor to infrastructure.  For example, 100,000 square feet of raised floor area (also known as white space) at 100 watts per square foot in a Tier III configuration would have a ratio of 1-to-1.  If at this time the density of the space increased to 150 watts per square foot, then the ratio would also increase to 1-to-1.5.  In other words, one would need 150,000 square feet of space to support the infrastructure with the same 100,000 square feet of raised floor.  This type of infrastructure was developed to meet the need of IT load support that – in most cases – never actually materialized.  As density increased, the industry began utilizing a proper measurement of kilowatt (kW) per rack instead of watts per square foot for a more accurate measurement.

More Power/More Efficiency

Once the new measurement model took hold and the industry began rating in kW or cost for kW, people began to clearly understand how much power was actually being used and at what cost.  This shift triggered an energy rating system known as Power Utilization Effectiveness (PUE), creating a universal measuring system of the efficient or inefficient use of energy throughout a facility.  As a result, data center managers were now held accountable for energy consumption causing them to seek free cooling and higher levels of efficiency, despite the fact that densities were increasing from 3 to 4 kW per rack to 16 to 25 kW per rack. In response, some facilities such as Yahoo! completely eliminated mechanical cooling (chillers) in favor of utilizing outside air to provide “free cooling” through a simple structure called the “chicken coop”.  While this worked well for Yahoo! and other similar data centers, it was not an ideal solution for most enterprise data centers and “hot aisle, cold aisle” became the norm.  Through this practice, operators were able to isolate the load, resulting in higher levels of energy efficiency and the trend of elevating temperature inside the data call.  The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) helped clarify the raised temperatures of server inlets, but the battle still remains to determine which PUE is smaller.

The shift towards energy efficiency and “greener” facilities propelled industry leaders to develop more innovative data center technologies including high efficiency chillers, adiabatic cooling, fuel cells, solar power and 380V Direct Current (DC).  These recent developments may foreshadow the future elimination of multiple Alternating Current (AC)/DC conversion and mechanical compressors, making way for a more distributed generation of clean power.  Likewise, alternative energy sources are also growing in cost efficiency.  One example are Bloom Box fuel cells from Bloom Energy.

For the the past 26 years, I’ve had a front row seat to the continuous evolution of the data center and with each change, I’ve had to adapt my environment to new design and construction standards.  Whether it’s an Internet or cloud data center, big open box space or modularized data halls and pods, I’m excited to see all of the growth and change that the next 10 years will bring.

380VDC Power Has Evolved, Providing Data Centers New Ways to Minimize Energy Loss and Improve Reliability

By Jim Stark, P.E., Principal of Engineering, Electronic Environments Corporation


Quickly becoming one of the most viable options when powering a data center, modern advancements in the Direct Current (DC) power distribution model are poised to increase energy efficiency and reliability like never before.

Traditionally, data center power distribution models follow a consistent formula, including multiple voltage power conversions between the electric utility and the server.  Distribution transformers, Uninterruptible Power Supply (UPS) systems, and Power Distribution Units (PDU) all introduce AC (alternating current) to DC conversions and voltage transformations in the power chain, oftentimes resulting in wasted energy.  This typical power distribution model can include a:

  1. Conversion from 480VAC to 480VDC within the UPS system
  2. Conversion from 480VDC back to 480VAC within the UPS system
  3. Transformation from 480VAC to 208VAC at the PDU
  4. Conversion from 208VAC to DC voltages within the server power supply

In order to eliminate many of these unnecessary power conversions, energy can be distributed at a DC voltage directly to the server power supplies as opposed to converting the DC power in the UPS back to AC power and then converting back again to DC at the server.  Depending upon the age and technology of power equipment utilized, the conversion to a DC power distribution model can result in efficiency gains of 10 to 20 percent thanks to a reduction in the number of power conversions.  Though the existence of DC power distribution in the data center industry is nothing new, modern technological developments have made this system more attainable than it was previously.  In fact, many telecommunications companies have taken advantage of the efficiency and reliability of DC power systems for decades.  Some of the benefits of DC power distribution over AC power distribution include:

  1. Fewer power conversions between AC and DC voltages result in a smaller parts count, which improves reliability and reduces maintenance costs;
  2. Fewer power conversions increases system efficiency and reduces energy costs;
  3. Less equipment may reduce capital investment of a comparable, new AC distribution system;
  4. Less equipment also reduces the footprint required on site; and
  5. Harmonic distortion and phase balancing are not a concern with DC power distribution, which eliminates the need for power filtering and minimizes stranded capacity.

Though many telecommunication companies have traditionally relied on low voltage DC systems (48VDC), the higher power consumption requirements of data centers fit better with 380VDC systems. Since data center servers run with higher power densities, this results in an extremely high current draw at 48VDC and requires much larger conductor sizes to provide ample power. The use of 380VDC eliminates this need, while working well within typical server power supply limits.  Since they operate in the same voltage range, users of 380VDC can additionally benefit from the ability to integrate with renewable energy sources such as photovoltaic (solar) arrays and fuel cells.

Two major issues which have delayed the acceptance of 380VDC systems in the past include: the availability of DC power systems and server power supplies, and safety concerns related to high voltage at the rack and server levels.  Thanks to recent innovations and advancements, DC power systems are now more readily available, prompted by the successful deployment of DC distribution in Asia and Europe and due to groups like EMerge Alliance, which have developed standards for the commercial adoption of DC power.  Noting the potential of this shift in data center power distribution, several manufacturers are now producing DC circuit protection and power supply cord connectors which address concerns with user safety related to DC voltage and arc protection.

The data center ecosystem is experiencing an exciting shift in traditional practices, making room for the development of a more sustainable environment as 380VDC and other energy efficient practices become widely adopted.

Join us on December 9 at DatacenterDynamics Converged Dallas to explore this topic further when we present, “Is it Finally Time for 380VDC Power in the Data Center?” at 12:20 PM local time.

Not Ready for Winter? Your Data Center Humidification System Should Be

By Jim Lundrigan, Vice President of Operations, Electronic Environments Corporation

Lundrigan_Head_Shot (2)

The cold is almost upon us once again and just like people, data centers can be prone to the winter blues, too.  As the temperatures drop and humidity decreases, it is important to ensure the necessary environmental adjustments are made within data centers to protect equipment.  This entails ensuring equipment which may have remained inactive during the summer and fall months is now able to operate with higher frequency at peak efficiency.  In the cooler, drier climate brought on by the changing seasons, this requires maintaining proper humidity levels, which is essential to achieving high availability and reducing operational costs within the data center.

Proper maintenance of data center humidification systems is necessary in drier climates to prevent static electricity that can build up and discharge – typically caused by cool, low humidity air moving throughout the facility.  Static electricity and electrostatic discharge (ESD) can lead to damaged computing equipment, including instances of blown fuses.  For the majority of data center facilities, staying within the American Society of Heating Refrigerating and Air-Conditioning Engineers (ASHRAE) recommended humidity and temperature guidelines (64.4° F – 80.6° F; 41.9° F – DP-59° F dew point) ensures a highly stable and effective environment for the efficient and reliable operation of mission-critical functions.

Identifying and remediating malfunctioning humidification equipment is also key to preventing water leakage resulting from blocked drainage.  Water leakage can severely damage the unit and surrounding IT equipment.  Malfunctioning humidification equipment is also the culprit behind the less obvious excess water vapor, which can slowly deteriorate components of a cooling unit.  Well-maintained systems are critical to reducing nuisance alarms, return calls and their related high price tags between preventive maintenance (PM) visits.  Monitoring and changing set points can also result in substantial power savings and increased energy efficiency.  At Electronic Environments Corporation (EEC), we’ve noticed a trend, much like that of raising intake air temperatures, in which customers are lowering humidification set points from 45% to 40% to 35% to reduce energy costs over time.

EEC has been providing customers with strategic guidance across all areas of data center systems, designs and environments for over three decades.  We help our customers prepare for and proactively prevent future data center challenges by providing a comprehensive scheduling of inspections and repairs.  This includes critical elements such as ensuring humidification systems are functioning at peak efficiency through the modification settings while preparing for seasonal changes and cooler, drier weather.  EEC’s humidification system inspections encompass:

  • Starting a humidification system and performing diagnostics;
  • Checking condensation pump operations and cleaning as needed;
  • Confirming that set points are operating correctly;
  • Examining overloads, fuses and electrical operations to ensure proper functionality;
  • Removing and cleaning humidifier pans and drain lines from build-up and deposits;
  • Adjusting pan water levels while testing and adjusting water overflow safety devices;
  • Calibrating humidity sensors; and
  • Maintaining water filtration systems that feed humidifiers (where applicable).

EEC leverages deeply-rooted data center expertise to develop and deploy customized solutions for data center maintenance in order to accommodate each customer’s unique business needs.  Examples of our customized solutions range from steam canister humidifiers, which offer simpler troubleshooting but a higher replacement cost, to UV systems, which require more maintenance, or ultrasonic systems, which requires larger up-front investments but run more efficiently and produce long-term energy savings.

While maintenance is critical during seasonal changes, it’s important to inspect equipment regularly year-round to ensure data centers function efficiently.  Prepare your humidification system and data center for the coming cold and dryness.  While you may not be ready for winter, your data center certainly should be; your business depends on it.

PEN 2.0: The Next Evolution of Cloud Network

By: Jon Vestal, Vice President, Product Architecture, Pacnet

Over the past 10 years, cloud development and bandwidth-hungry applications such as cloud storage operations, videoconferencing and video streaming have continued their rapid proliferation in the market, consuming capacity and leaving traditional networks struggling to keep pace. Their propagation has spurred a growing customer need for a burstable hybrid cloud solution for Disaster Recovery, Ecommerce as well as flexibility in moving workloads from one location to another.  Moreover, today’s organizations also need compute, connectivity and storage resources to be dynamically scaled up or down according to demand. They also require access to these tools and systems without time or location restrictions, while still being able to maintain the utmost security.

As a result, we launched our award-winning Pacnet Enabled Network (PEN), the first pan-Asian Network-as-a-Service (NaaS) architecture to power cloud deployments in February.  The platform has proved to be a tremendous solution for our customers, enabling them to solve complex network challenges and build high-performance, cost-effective, scalable and cloud-ready networks.  Due to strong market demand, the platform was also extended into the United States in addition to deployments in Australia, Hong Kong, Japan and Singapore.  It is this same demand, coupled with new challenges spurred by rapid market advancement, which serve as the driving force behind Pacnet’s commitment to continued innovation.

Keeping Up with Advancing Technology

When our customers spoke, we listened – a nuance that I believe makes Pacnet unique amongst other providers.  In direct response to customer feedback and needs, we will be introducing the next evolution of the PEN platform, what we call PEN 2.0, in mid-September.

PEN 2.0 widens the scope of SDN, allowing a broader set of services in traditional network topologies to be deployed and scaled on demand.  For example, the platform allows carrier customers to create an individual network topology at a very granular level, eliminating complexity to create a clear network infrastructure.  PEN 2.0 further enables hybrid cloud deployment for our customers, facilitating connectivity from enterprise-class data centers and private clouds to any external cloud vendors and allowing customers to burst workloads from one end to another through our on-demand bandwidth.  PEN 2.0 also boasts a series of new features.

With the release of the enhanced platform, Pacnet has become the first carrier to deploy Network Functions Virtualization (NFV) solutions in an OpenStack environment, including vFirewall and vRouter.  The integration of NFV into the OpenStack environment did not come without its challenges.  One issue faced by our development team was the inability to reuse network resources with the OpenStack networking module, Neutron.  For example, upon creating a virtual network, Neutron prevented the removal of a virtual appliance and its replacement with another virtual appliance while still leveraging the original physical infrastructure.  The issue was resolved when our developers accessed and modified the OpenStack source code to our specific needs – a key reason for Pacnet’s initial selection of OpenStack.

PEN 2.0 also features a Virtual Local Area Network (VLAN) that connects multiple endpoints for different application environments with varying characteristics to meet specific customer needs. The introduction of VLAN has allowed Pacnet to have a dedicated Ethernet connection directly to the Amazon Web Services (AWS) environment, leveraging the PEN 2.0 platform to extend these circuits anywhere across a customer’s network.

The third and final new feature of PEN 2.0 is the integration of approval chains to ensure secure access to the service platform.  The approval chain allows customers to define their own workflows for the PEN 2.0 environment through the workflow management tool.  Only a series of users or user groups who have been granted permission are allowed to approve workflow / environment modifications.

The Twin Technologies

While SDN separates network control from the physical infrastructure such as routers and switches to allow support of a network fabric across multi-vendor equipment, NFV focuses on virtualizing network components, or decoupling important network functions from physical devices.  Essentially, it is the delivery of a virtualized router within the cloud.

Together, SDN and NFV are synergistic – capable of orchestrating the delivery of a virtual appliance and the network with no human interaction as well as enabling self-provisioning end to end.  SNS Research estimates that the SDN, NFV and virtualization will account for nearly $4B in 2014 alone, growing at a CAGR of nearly 60 percent over the next six years. By 2020, SNS estimates that SDN and NFV will enable service providers to save up to $32B in annual CapEx.

Tell us your requirements and business objectives now, and let our mighty PEN help propel your business.
