Study Shows U.S. Data Centers are Wasting Valuable Power


Energy efficiencyPhoto Credit:


The need for organizations to improve energy efficiencies has never been greater, as the price of fuel is increasing and several areas of the country are already mired in severe drought.

In fact, according to a new report from the U.S.-based Natural Resources Defense Council (NRDC) titled “Scaling Up Energy Efficiency Across the Data Center Industry: Evaluating Key Drivers and Beliefs,” U.S. data centers need to start doing more to reduce the amount of energy they are wasting in order to help improve environmental conditions . The report indicates that energy efficiency improvements have been slow to implement.

As the report explains, U.S. data centers waste about $3 billion worth of power every year. And last year, U.S. data centers used about 91 billion kWh of energy. By 2020, this number will skyrocket to 140 billion kWh. Providing this additional power will take 50 large coal-based power plants—which will generate 150 million tons of pollution—or its equivalent.

But as the report also explains, curbing data center power waste by 40 percent could save at least $3.8 billion. This is a savings of 39 billion kilowatt hours, annually.

Power distribution and monitoring software is a critical part of reducing waste in the data center. Operators need to be able to understand which devices are consuming the most amount of energy, and how they could better allocate energy throughout the data center to reduce unnecessary power draw. Until more data centers begin to actively measure and reduce the amount of electricity they are using on a daily basis, the amount of waste will continue to grow.

NASA Exploring Options for a More Energy Efficient Data Center



The National Aeronautics and Space Administration (NASA) is currently looking for ways to make its data center at the Goddard Space Flight Center (GSFC) more energy efficient. The administration recently released an official request for information as it looks to devise a short-term solution, a transitional solution, and one that will support its long-term energy goals.

The request for information indicates that NASA is looking to invest in the following power management options, in addition to other data center solutions:

• Transformer-free UPS
• Power distribution units (PDU)
• Remote power monitoring at the rack level
• Server utilization solutions

Why is NASA exploring ways of becoming more energy efficient? The decision to investigate data center power-saving strategies is part of the Federal Data Centers Consolidation Initiative (FDCCI), which was established in February 2010 to combat unsustainable data center growth. The FDCCI aims to reduce the cost of data center software, hardware and operations. To accomplish this, it asked agencies to consolidate at least 800 data centers by 2015. The purpose is to drive cost savings and sustainability efforts and increase security in data center environments.

Here at Server Technology, we support the FDCCI and believe that every organization has a responsibility to consolidate and optimize data center operations. And we have all of the equipment that you need to consolidate your data center. Our PDUs and first-class power management software will give you the ability to monitor your power consumption and save valuable resources, including rack space.

Successful SDN Migration Needs a Reliable Power Monitoring Solution


SDNLab header2

How safe is software-defined networking (SDN) for data centers? Here at Server Technology, your source for data center power monitoring solutions, we hear this question a lot. Our response is that it would be unwise to invest in such a new and emerging technology without the ability to ensure safe and responsible power distribution throughout its life cycle, from installation to when it’s time to scale.

SDN, like many other emerging technologies currently being considered for use in data centers, has the ability to facilitate cost savings by driving network efficiencies. As the technology allows for the physical separation of the control plane from the forwarding plane on a network, the network becomes more agile, easier to program and control. So, by this means, SDN allows the network infrastructure to be abstracted and capable of hosting services and applications using the OpenFlow protocol.

But achieving a carrier-grade network through SDN does not come without its share of risks. There are many concerns about SDN, which will be addressed in the SDN Lab at the upcoming Interop New York Conference (Oct. 1-2 at the Javits Center). The purpose of the lab is to ascertain whether SDN, a technology that is still in its nascent stage, is ready for full-scale use at the enterprise level. Right now there are many concerns about SDN performance, security, interoperability and scalability. To ensure continuous energy for the experiments at Interop, Server Technology has been tasked with providing power monitoring throughout the expo.

One SDN concern to be addressed by the lab is power draw. For capacity planning, operators need to see SDN power draw in real time and whether system crashes can be avoided. 

Server Technology’s data center power monitoring solutions, which include data collection management, power measuring and device-level management, make it possible to gain a crystal-clear view of how every piece of software and hardware interact in the data center. If you are considering installing SDN, or other new technologies, click here to learn more about how Server Technology can provide your business with the critical oversight necessary for ensuring a safe migration.

On Oct. 1-2, New York City’s Javits Center will host the much anticipated Interop expo, a premier convention where network professionals will come to test and showcase the latest business-driving technologies. And this year, all eyes will be on Interop’s Software-Defined Networking (SDN) Lab, a purpose-built lab designed to test open source SDN software, as well as vendor-specific SDN systems and applications. Its purpose will be to ask the question of whether SDN is reliable enough to drive data center efficiencies.

As a complex multivendor standards-based testing facility, Interop’s SDN Lab presents a challenge to vendors that require constant and reliable power distribution. In order to freely experiment with bleeding-edge technologies, vendors need a way of ensuring that they will not overload circuits and cause outages—a problem that if unchecked could have disastrous consequences for the entire expo.

Server Technology, a longtime power monitoring and distribution provider for Interop, is proud to announce that it has been selected to provide essential power distribution services for the SDN Lab as it tests the interoperability of SDN products and demonstrates how they can be used in a variety of different environments.

Server Technology’s power monitoring software will provide necessary oversight as network professionals experiment with changing workloads and conditions, route various amounts of traffic to devices, and integrate applications and network resources using APIs and controllers. In so doing, Server Technology will prove how power monitoring is absolutely essential for companies looking to experiment with new technologies.

SPM Guides You Forward : Part Five - What happened?


alg resize titanic sinks jpg resized 600


This is the fifth in a series of blog posts providing tips and tricks for answering common data center questions with the use of SPM. In my last post, I gave some guidance on answering, “How do I prove power system redundancy?” Though uptime is of prime concern, there will occasionally be outages at some level of the power chain which leave us scratching our heads.

Question: What happened to cause this outage?

Depending upon who you ask, anywhere from 40% to 80% of outages are caused by “human error”. Of course, there is wide variation in the definitions of “outage” and “human error”, but the point is that power outages caused by human error are presumed to be correctable and preventable.

  1. Before you worry about the details of what happened, you must have received notification that something of negative impact did occur. SPM brings these alerts to you in the form of emails.
    1. Meaningful alerts start with naming the components and sub-components of a system appropriately based on connections with other equipment and physical location or relevance. SPM allows access into the depths of the Server Technology CDU for convenient naming of infeed power connections, outlets to rack devices, and environmental sensors. Additionally, groupings of outlets and racks/infeeds allows for larger scale organization of equipment.
    2. The alerts are, of course, based on thresholds that describe the in-bound / out-of-bound conditions of particular power and environmental measurements. These are best set with the culture of the organization in mind. That is, set them initially lax or tight based on whether it is better to receive under-alerting or over-alerting. Then, most importantly, review those threshold levels on a regular basis to keep your system in tune with the organizational goals.
    3. Finally, SPM will provide its alerting through email. Be sure to set these to send to the right personnel, and only the right personnel.
  2. Once you get that alert, it then becomes incumbent upon you to identify what led up to the condition of concern. SPM provides trending and reporting of all critical values for these purposes.
    1. Create meaningful trends within SPM to display the critical power and environmental parameters. The trending configurator allows for multiple point metrics, overlaying of time periods, and overlaying of different types of metrics such as temperature with power.
    2. Once an event has occurred, it can be quite useful to keep a close eye on that particular section of the data center or particular equipment. SPM’s built-in live-updating Views configurator will allow each user, no matter their responsibility to see what is happening in the data center while performing their everyday tasks.
    3. Continuing on the proactive discussion, any trends and reports you build for understanding recent events can be, in turn, set to a scheduled email to keep you informed of conditions that may be approaching alert again.
  3. Returning to the concept that most downtime in the data center is due to human error, an analysis of what happened leads to the question of “who did what?” and “what can we do better?”
    1. The first step to accountability and traceability is to assign appropriate user rights to personnel interacting with SPM. Authentication can be setup using LDAP(S) or TACACS+ like most other network software. Additionally, setup user rights within SPM to be sure that only the right people have access to make changes to the system or to control CDU outlets or configurations.
    2. When an alert occurs that could be personnel related, be sure to check the SPM logs for event details and times.
    3. Finally, SPM can help avoid certain personnel errors through scheduling maintenance outlet control actions. This can be particularly useful when the desire is to be sure that certain equipment is powered up at particular times.

Though your data center may be designed to Tier IV, and your personnel and processes proactively optimized, downtime will happen at some time at some level in the power chain. It becomes incumbent upon the responsible personnel to find out “What happened?” to cause the outage. SPM helps find the answers.

Upgrade Your Power Distribution With HDOT Alt. Phase PDUs


describe the image


Right now data center power consumption is on the rise in North America, as the number of racks increased by 9.1 percent in Canada and 4.3 percent in the U.S. in 2013. All signs are showing this trend continuing through 2014 and beyond as data centers standardize on high-density equipment to achieve more processing power in a smaller space.

As power requirements increase, data center managers everywhere are looking for ways to deliver more power to the computer cabinet in a cost-effective way. One way they are accomplishing this is by upgrading their power distribution systems from single phase to three phase.

Why are three phase systems more cost efficient? A single phase power cord contains three wires. A three-phase delta power cord contains four wires. For that one additional wire, three phase delta delivers 52% more power than single phase. But it doesn’t come without risks.

Thankfully, Server Technology makes it easy and risk-free for you to migrate to three phase power distribution with its new line of alternating phase power distribution units (PDU).  These PDU’s alternate the phase pairs on a per-outlet basis instead of a per branch basis.

In addition, Server Technology has incorporated its patented High Density Outlet Technology (HDOT) into the Alternating Phase PDU’s, resulting in the maximum achievable number of outlets in the smallest form factor PDU. This provides the utmost flexibility when it comes to supporting the myriad array of IT equipment in the rack.

Here are some major benefits HDOT Alternating Phase PDUs can provide:  

Phase Balancing simplified:  The inherent design of Server Technology’s Alternating Phase PDUs simplifies the task of balancing equipment loads across the multiple branches of the PDU.  The alternating phase outlet arrangement allows a simple ‘top down’ deployment of the equipment connections to the PDU, resulting in minimal cord runs, which de-clutters the back of the rack and improves air flow.

Less chance of power overload:  Unbalanced branches can result in a circuit breaker trip during a fail over event. Alternating phase PDU’s minimize the chance of running with unbalanced loads due to the ease of balancing. 

Data Center Power Efficiency:  Large Phase imbalances in the data center can lead to voltage and current distortions on the individual phases, increased heat dissipation, and reduced equipment life. Phase balancing in the data center starts at the PDU.  Alternating Phase PDU’s simplify the phase balancing challenge.

More Outlets in a Smaller Space: Taller racks with smaller footprints push the need for smaller, denser PDU’s. Server Technology’s (HDOT) provides the highest outlet density of any network PDU on the market.
