DVL and Emerson Network Power hosted a Data Center Infrastructure Management Seminar at the Microsoft Technology Center on Friday (2/24/12) - we had a great turnout and discussion. If you missed the seminar, click here to check out the presentation.

IT and facilities organizations have invested heavily in technology resources (people, processes, and tools) to manage the data center infrastructure, they have failed to achieve the promise and potential due to critical gaps between their data center facilities and IT infrastructure components. A new perspective on managing the critical infrastructure gaps is emerging that recognizes:

• The importance of 'real-time' data to understand the true capacity of available infrastructure
• The criticality of interdependencies between logical and physical layers
• The need for holistic management capabilities and visibility of IT and facilities infrastructures
• The need for more powerful management tools that offer a rich, visual view of the infrastructure and can guide design and change management 

>> Check out the FOUR TRENDS Driving the Future of Data Center Infrastructure Design and Management.

Energy costs are the fastest-rising cost element in the data center. Based on current trends, the EPA estimates that energy consumed by data centers will continue to grow by 12 percent per year. Power and thermal energy consumption balanced with energy savings is one of the major responsibilities of facility and IT managers. Intel Data Center Manager group has observed how the data center is now a source for CIOs and their technical teams to add to the bottom line through increased power and cooling efficiency. 

Leading data centers are ramping up to real-time power and thermal management. There is a growing recognition of the ROI benefit through monitoring usage by device. This provides real-time energy consumption data in relation to the actual workload for individual servers and groups of servers. Collecting data of the actual power and thermal trends over days, weeks and years provides ROI benefit through the following: effective capacity planning, power provisioning, device utilization or replacement, preventive maintenance, and failure or disaster avoidance.

Here are three value drivers for power and cooling efficiency, outlining the various options for CIOs to reduce costs in the data center and contribute to corporate profitability.

One thing we are seeing more and more of today is confusion over what temperature and humidity parameters data centers should be designed for.  Most of the discussion seems to assume that there is a monolithic block of data centers that can all be designed the same way.  Nothing could be further from the truth. 

Most of the data centers in existence today have a mixture of technologies and systems that all have varying environmental requirements.  We typically refer to these as mixed use data centers.  Unlike an E-Bay, Google, Microsoft or Apple data center, there is not rack after rack of the same equipment, all with similar operating requirements.  That is a very small, but highly publicized part of the market.  Everyone loves to write about the latest designs from Yahoo, Google, Apple, Etc, but they are not representative of the larger data center market as a whole. 

I know these data centers don’t get the publicity of the designs that push the envelope, but they are much more representative of the data center market as a whole.  We certainly do our share of cutting edge designs, but the majority of our clients are looking for ways to add capacity and increase the efficiency of their “traditionally designed” data centers.  This may include air and water side economizers and/or more efficient UPS systems and distribution.   The designs vary significantly, but the one thing these data centers have in common is that they all have equipment requirements that would preclude some of the modern designs that have little to no temperature and humidity control.

Every 3 to 4 months, DVL hosts a small Data Center Users' Forum.  The mission of the DCUF is to provide a commercial free forum where members collaborate on relevant mission-critical issues, new technologies, customer testimonials, and best practices affecting reliability, availability, and lowest cost of operation.

Last Friday, the DCUF, which includes IT and facilities professionals from multiple industry types, discussed various topics including:  Data Center Infrastructure Management, metering and trending, bridging the gap between IT and Facilities, outsourcing vs. keeping everything in-house, industry power trends, passive RFID asset technology, containment, power outage/root cause analysis.

An alternative approach to conventional alternating-current (AC) power uses a direct-current (DC) power distribution scheme throughout a data center. Most data center server racks are not currently powered this way, but with the advent of servers on the market that can operate with either AC or DC, it is possible to use the DC powering approach, thus eliminating extra power conversion steps and losses. Other benefits include reduced cooling needs, higher equipment densities, and reduced heat-related failures.

This web site describes two pioneering demonstrations - one where direct current is distributed at the facility level to racks of computers that have been modified to directly accept high voltage direct current (DC) and another where the DC power conversion occurs at the rack level and DC is then directly distributed to servers within the rack. In typical data centers, the loss in electrical power through conversions of alternating current (AC) to DC to AC to DC occurs for all power flowing to the IT equipment. Efficiency gains have a magnifying effect by reducing need for HVAC (e.g. 10% saving at the UPS level mean about 10% energy savings for the entire data center, compared to a very efficient AC baseline case and assuming the HVAC system consumes as much power as the IT equipment).  Source: Lawrence Berkeley National Laboratory .

A New Study Reinforces Case For DC Power Saving

It’s been five years since a study by Lawrence Berkeley National Labs outlined the potential for DC power distribution to cut data center energy use by 10 to 20 percent. But adoption of DC in data centers remains limited, even as the industry aggressively pursues a wide array of other energy savings strategies.
