In my last post, I discussed how we're reducing acoustic levels for equipment that cools today's fast, high-powered computer systems. Today, I'm exploring the other side of the equation: heat reduction.

In our world of growing cloud-based services, users want more online storage, faster video streaming and quicker access to information. In a recent article in The Data Center Journal, Jeff Clark discusses how, as energy prices and demand for cloud services increase, the demand for efficient systems to save data center floor and rack space is also growing.

While higher density data system racks can reduce facility size requirements, their cooling systems also need to accommodate higher heat loads within these smaller areas.

With an increase in rack density – both in power and airflow impedance – the challenge of keeping these systems cool while still remaining within old standards limitations is becoming significant. The dilemma? How to keep one’s data center upgrade costs low while providing the additional cooling that’s essential for higher-power density equipment which can now approach 20+ kilowatts per rack.

In this changing environment, equipment manufacturers must accommodate aging standards while also meeting higher cooling flow needs in denser rack systems. As rack densities increase, air-cooling becomes more expensive and more challenging.

As cloud-based services continue to grow, ebm-papst continues to refine technologies that help maximize cooling capacity of our air movers to meet a wide range of data center requirements. Whether it’s our new line of highly efficient compact RadiCal impellers or high-pressure capable axial fans, such as our new DV6300 series, we are always pushing the improvement curve.

Have you experienced any of the above cooling challenges in your IT/Telecom applications? If so, how did you resolve them? What solutions did you choose moving forward? We welcome your feedback in the comments box below!

3 Ways to Prevent Data Center Crises During a Power Outage

Last year’s heavy snowstorms and Hurricane Sandy kept data center operators on their toes as they battled power outages and struggled to keep their cool – literally. These acts of nature got data center operators thinking more about ways to prevent data loss and overheating, long before the next storm hits.

1. Look to the cloud

At the Data Center World expo, from April 28 to May 2, a keynote panel featured two data center stories straight from the eye of Hurricane Sandy. For Alex Delgado, the global operations and data center manager for International Flavors & Fragrances (IFF), cloud email prevented communication headaches, and a back-up facility prevented the company from losing a single order. Donna Manley, IT senior director at the University of Pennsylvania, also relied on the cloud, backing up documentation on Box.net in case servers went down. 

2. Plan for a crisis during the design phase

For Kevin Dickens, deputy director and senior projects engineer with Jacobs Facilities, Inc., Hurricane Sandy also pointed to a need for HVAC back-up. Data center operator zColo experienced issues with its generators during the storm and decided to shut down portions of the cooling system to avoid losing the entire operation. Temperatures inside the center climbed to above 100 degrees Fahrenheit, causing zColo staff to place fans around the center, open windows and shut down some equipment.

“I have wondered what it must have been like for zColo’s mechanical team when they were informed that in order to keep IT online, they would have to shed mechanical load,” says Dickens. “Did they have any idea how the space temperature would react and how fast? Could anyone quantify the near-term and long-term risks to the IT equipment?”

Dickens addresses his own questions by pointing out that the answers should be determined during computer room air conditioner (CRAC) unit design – not during crisis time.   I would expect that the age of the CRAC’s should be reviewed along with their efficiency.  This brings us to the third topic.

3. Consider your CRAC’s age

Another consideration when creating your crisis plan: How old is the CRAC? Over 70% of the 500,000 data centers around the world are greater than 7 years old.  An old and less-efficient CRAC will put a drain on your utility bill as well as eat at your UPS capacity when crisis hits. Replacing fans within the CRACs with direct-drive EC fans means less wear and tear and, therefore, increased reliability and a longer life span.  Other benefits include:

  • 10 to 30 percent in energy efficiency gains.

  • A return on investment within six to twelve months.

  • Lowers the UPS requirements – increasing capacity for power outages.

ebm-papst offers the largest range of fan and blower sizes, along with some of the most efficient motor technology in the world.  We currently supply a range from small tubeaxial fans in blade server applications up to some of the largest fans used for data center building facilities cooling.  This proficient knowledge and product blend in IT, HVAC, and Data Center equipment position us to best address upgrades to existing cooling equipment as well as brand new cutting edge ‘green’ builds with alternative cooling methods.

ebm-papst: The Future of Data Centers

Posted on Thu, Mar 15, 2012
by Joe Landrette, Market Manager at ebm-papst.

The US consumes about 4.40 trillion kWh of electric energy (Tomorrow is Greener 10/2011). Two percent of that power consumption, or 88 billion kWh, is used by data centers, which provide us with services like Apple's iCloud or Microsoft’s SkyDrive.

Because power savings is critical for hardware manufacturers and their customers, many companies are migrating from large facility data centers to portable/modular data centers that are often set up within sea containers. This new generation of data center is often fitted to house many racks of IT equipment that have ultra efficient cooling systems inside.

Not only can modular/portable data centers be manufactured and deployed more rapidly than traditional data centers, they also employ cooling solutions that can be 30 times more efficient than facility-style cooling systems and can save up to $500,000 a year in energy costs!

Because the majority of portable and modular data centers don’t have the same heat/cooling duct losses experienced in traditional data centers, the new configurations can super-charge their energy efficiency by incorporating ebm-papst’s range of EC blowers and fans, from our small 80mm fans up to 1250mm models.

The new modular/portable data centers also provide an opportunity for ebm-papst Inc. to offer builders air flow and design management strategies and custom sheet metal assemblies. Our products and engineering support services are helping shape how data centers are joining the earth-friendly movement and changing the future of both indoor and outdoor data storage.
