Data Centers Focus on Greener Power
With carbon regulation looming on the horizon, companies with extensive data center operations are taking a harder look at the origin of their power, and its implications in a regulated environment.
“The biggest part of our carbon footprint is the amount of electricity used to power the IT equipment in our data centers,” said Christina Page, the Director of Climate and Energy Strategy at Yahoo. “All electrons are not created equal.”
Companies like Yahoo are seeking to use less power and buy a larger percentage of their energy from renewable sources such as hydro, wind and solar power. In most cases, that means building or leasing data centers in locations where utility providers offer renewables in sourcing their electricity.
The Bully Green Pulpit
The issue is coming into focus for data center operators as the President Barack Obama has used a series of media events – including a visit of MIT last week and this week’s tour of a Florida solar power facility – to ramp up discussion of his cap-and-trade plan for regulating carbon emissions in the U.S.
Regulation will likely introduce new financial considerations around renewable energy, and reinforce the existing focus on data center efficiency, according to panelists at this month’s Data Center Energy Efficiency Summit hosted by the Silicon Valley Leadership Group (SVLG).
“We look at this potential for regulation as opportunity rather than a harbinger of doom,” said Mark Thiele, director of business operations for R&D at VMware. “Carbon right now is at the top of the hype cycle. The reality is about efficiency, and saving our companies money. Those of us who care about the environment now have a stick to wield.”
Energy Efficiency: Job One
The immediate opportunity is in funding efficiency projects, or as Thiele puts it, ”how we own what we already have.” There is evidence that efforts to improve the energy efficiency of data centers are extending beyond the largest providers, whose huge power bills have made efficiency a business imperative.
Yesterday the data center trade group AFCOM reported that 71 percent of its members are pursuing energy efficiency projects. But barriers remain. “I really surprised that 22 percent tof our members reported that they haven’t gotten a commitment (on energy efficiency projects) from senior management,” said Jill Eckhaus, the president of AFCOM. “The data center sucks a lot of energy, so it’s being looked at in a big way.”
Hydro, Solar Implementations
VMware and Yahoo are among the companies that have built data centers in central Washington, where the local utility power is almost exclusively hydro power from dams on the nearby Columbia River. Hydro is desirable because it is both green and affordable.
In other parts of the country, i/o Data Centers, AISO and Emerson Network Power are integrating solar power into their new data centers. But the price and scalability of renewable power presents challenges to on-site generation of renewable power by data center operators.
As innovation is gradually whittling down the cost of renewable energy, the disparity between renewables and coal may also be altered by regulation. The EPA’s Ben Machol said pending legislation will not just boost renewable energy sources, but could also have cost implications for utilities that relay heavily on coal in their power generation.
Higher Pricing for Coal?
“Coal plants would need to put in controls for greenhouse gases,” he said. “What that will mean for data centers is primarily prices going up. In an environment of rising power prices, energy efficiency will pay back very quickly. It’s a no brainer.”
While some attendees at the SVLG event were critical of the potential for regulation to increase the cost of coal-based power, others said the industry needs to consider a broader context for the issue. ”Dirty electricity is already expensive,” said John Stanley of the Uptime Institute. “It only looks cheap.”

RACKWISE Data Center Manager (DCM) is an enterprise class software solution. It enables Visualization of your entire data center infrastructure from the data center through the rack to devices and components within those devices. Full Documentation is built into the system for managing today’s complex environments. Modeling, and unlimited “what if” scenarios are core parts of the software. Data Center Manager (DCM) provides the ability to analyze data in tabular and graphical formats. Make informed decisions, enable day to day efficiencies, and operations necessary for proactive Management of the data center with DCM.
Visualization provides a dashboard display for a high level view of the data center. Selectable layers can be added to display power consumption, heat generation, current, and either power or signal port availability. Additional layers can be added to display door swings, hot cold aisles, location and density of perforated tiles, etc., to create truly customized displays. Users can drill through to greater detail, from the data center, to the rack, to the device, and components, including: blades, power supplies, drives, etc.
Documentation provides clear and descriptive reporting on the IT infrastructure. Customizable reports detail what resources are used and summarized per row and data center. Custom properties can be used to show how devices relate to applications. Standard reports range from an assembly report that provides step by step instructions to assemble and cable a solution, to connectivity reports, power consumption, environmental reports, and asset management reports. All reports can be customized to data center, row, rack, or custom grouping.
Modeling allows the user to perform unlimited “What if” scenarios. RACKWISE DCM quickly determines the impact of data center consolidations, or the resource consumption associated with new data centers. The user can make detailed comparisons of proposed equipment upgrades versus the current environment. Optional trend and historical reporting provides crystal clear visibility into where resources are being consumed over time, and when they’re likely to be exhausted.
Analysis provides instant access to critical information and enables decision making capability on key data center issues. Direct access to information such as availability of space, power, heat and cooling, port availability, and remaining weight capacity in racks, allows the user to make critical decisions with confidence. Advanced Power Management, provides the ability to peer into the power system, understand the redundancy levels of critical servers, and other equipment. The advanced power and reporting package also provides full understanding of the impact of power source, UPS, or PDU shutdowns. Further the system determines if the remaining power infrastructure will be over taxed in the event of an outage, resulting in a cascading failure situation.
Management capabilities allow the user to deploy and decommission devices quickly and easily. Track equipment through receiving, staging, commissioning, decommissioning, and storage. In addition, RACKWISE DCM tracks changes to the data center infrastructure at the data center, rack, and device levels. Custom properties can be used to map applications or other information to devices, providing a clear understanding of what impact the shutdown or failure of the device will have. Planning for new equipment is greatly simplified with RACKWISE DCM’s ability to locate and reserve space, power, cooling, ports, and weight load availability. Additionally, sophisticated searches can be made to locate physical infrastructure components based on your search criteria.
