IT energy efficiency,
Green data center
Northern California utility Pacific Gas and Electric Co. made headlines by finding novel ways to offer rebates for energy efficiency in the data center. The company’s programs have become a model for other utilities in the state and around the world. Mark Bramfitt had headed up PG&E’s data center energy initiatives, until last Thursday when Bramfitt announced he was leaving PG&E.
John Sheputis, CEO of Fortune Data Centers and a recipient of nearly $1 million in PG&E data center efficiency rebates was at the Silicon Valley Leadership Group Data Center Energy Efficiency Summit when Bramfitt broke the news.
“The reaction from the crowd was impressive… and for good reason. Mark is an excellent speaker, a very well known entity in the valley, and among the most outspoken people I know of regarding the broader engagement opportunities between data centers and electricity providers,” Sheputis said. “No one has done more to fund efficiency programs and award high tech consumers for efficient behavior.”
Bramfitt and PG&E started focusing on data center utility rebates and incentives in 2006. According to Bramfitt, PG&E’s data center program saved three megawatts of load in 2007, and doubled that in 2008 saving seven megawatts. But getting IT pros to jump through the hoops to get the rebates was a difficult task.
“The effort Mark was undertaking was critical and immensely difficult,” said Mark Thiele, Director Business Operations R&D at VMware and co-founder of Data Center Pulse. “I sincerely hope that PG&E hires someone to pick up where Mark left off. However, if his replacement is to be successful, I think s/he will have to do more to bring the public and government agencies into the fight. It’s possible that getting new blood, as well as renewed enthusiasm for the effort will be just what the doctor ordered.”
“PG&E had the leading program in the US to reward the end user for their efficiency choices, but it was rather difficult to obtain the rebates,” said Dean Nelson, data center director at Ebay. Many companies found the effort not worth the return. I think Mark Bramfitt had some very good successes and all the right intentions but lacked the future support within PG&E to continue. I believe it is crucial that the utilities (all of them) interface with their corporate customers, and each other, to decrease consumption and optimize efficiencies. I hope that PG&E has plans to fill this position and/or refocus the program to make it simpler for data center users to take advantage it. They have momentum and should continue. Killing it would be a mistake.”

PG&E
Hosting and wholesale data center provider Fortune Data Centers walked away with a $900,000 check from Northern California energy utility Pacific Gas & Electric for making energy efficiency investments in its new San Jose data center.
Fortune opened the new data center for business in April, 2009, reclaiming a former manufacturing site. After phase I of construction, the 78,000 square foot facility has 43,000 square feet of IT space, and the company is claiming a PUE of 1.37, which if correct would mean that the facility’s data center mechanical infrastructure is highly efficient compared to the industry average of 2.0. See Mark Fontecchio’s article for more on evaluating public data center PUE claims.
The utility rebate came from PG&E’s High Tech-IT Facility program, which offers incentives for California data centers to reduce energy demand.
According to Fortune Data Centers CEO John Sheputis, the energy savings came from optimizing the cooling system and purchasing the most efficient uninterruptible power supply systems possible. Sheputis said the PG&E payments offset about half the cost of the premium for implementing high efficiency infrastructure.
PG&E engineers were very involved in the design and commissioning of the project. “PG&E has a commissioning agent to make sure you’ve installed the energy efficient devices and to make sure that it’s working,” Sheputis said. “They have to see the equipment operating. We get payments as the measures are brought online. They’re not allowed to just go around handing out checks.”
While $900,000 is a lot of cash, it’s not the largest data center utility rebate so far. NetApp scored $1.4 million from PG&E for its data center efficiency measures. Sheputis golfs with NetApp data center execs, and joked that “They’re dissing me for not getting as big a check as they did.”

In our story on extending UPS battery life, I wrote about how monitoring battery capacity is crucial. Well, Jim Reed, the president of battery monitoring company Power Data Systems in Boonton, N.J., wrote to add a few things to that list. Here’s what he wrote:
Hi Mark, we read your article “Four Ways to Extend Data Center UPS Battery Life”. While we agree with everything that you had suggested you neglected to mention anything about using permanent online battery monitoring systems with ohmic measurement capability that will provide accurate data into the health of the battery string right to the cell or jar level. This data will provide advance warning of batteries that are starting to exhibit a problem that will eventually lead to an early death. The IEEE has written a standard for battery monitoring called “IEEE Guide for Selection and Use of Battery Monitoring Equipment in Stationary Applications” IEEE Std 1491.
Another reader wrote in regarding my point that mixing batteries of different ages or internal resistances can prompt batteries to die more quickly. George Pederson, the business development manager at Rockaway, N.J.-based battery monitoring company BTech Inc. said that doesn’t mean you have to replace the whole battery string whenever one battery needs replacing. He elaborated:
This is not true, it is not the new battery that unbalances the string, it is typically because the battery unit that failed was not identified sooner and it had already done the damage to the other units. There is one caveat to that and that is, the replacement unit has to be fully charged a lot of times the service company will simply take a unit straight from the battery manufacturer and put it in service without a refreshing charge to ensure that the unit is fully charged and this will result in an unbalanced string.
Quite simply if the job is done correctly there is no reason why users shouldn’t get the full five years from a high rate battery.
Thanks to both Jim and George for writing in.

data center cooling
London-based Future Facilities released Version 5 of its data center computational fluid dynamics software, 6SigmaDC. Large data centers and facility design consultants (including Emerson/Liebert’s data center consulting arm) use the tool to model data center cooling.
New features in version five include:
-Modeling internally cooled cabinets so they can be registered for inventory purposes and accounted for in the power system as well as for power scaling needs.
-Modeling equipment weight to assess whether any given layout will breach floor loading limitations.
-Cable penetrations can now be attached to the raised floor to account for the situation where they are installed before racks and cabinets.
-The infrastructure outside the facility can now be included in graphical views and animation can be generated to demonstrate how airflows develop.
While data center pros rave about the tool (6SigmaDC won silver in our 2007 Products of the Year) it comes at a steep price, up to three times the cost of data center CFD software from TileFlow, according to data center design consultant Pete Sacco.

Data center power,
Uninterruptible Power Supply
Last week, Eaton Corp. announced a new uninterruptible power supply (UPS) with a 400V/230V power distribution that’s uncommon in U.S. data centers.
In most data centers, power comes from the utility at 480 volts and then gets stepped down to a 208/120V distribution at the server level. With the Eaton product, the power comes from the grid at 480 volts and gets stepped down to the 400/230V distribution, which is commonly used in Europe, Asia and South America. According to an Eaton whitepaper, the 400/230V distribution is 4% more efficient than the traditional UPS that distributes at 208/120V.
“It only took us about 100 years to get to where the rest of the world has been for decades,” Peter Sacco, president of data center engineering firm PTS Data Center Solutions, wrote in an email to me. “The technical advantages of 400V are undeniable and I believe and outstanding improvement to our 208/120V standard as well as better than DC power distribution.”
But hold on.
“However, don’t buy a new electric razor just yet,” Sacco advised. “Until there is broad acceptance by the power distribution industry, don’t expect to see it widely utilized just yet.”

Uninterruptible Power Supply
In a new whitepaper, flywheel uninterruptible power supply (UPS) company Active Power makes the case for, you guessed it, flywheel UPS.
The paper points to two studies, one by the Lawrence Berkley National Laboratory and the other by the Silicon Valley Leadership Group, showing that flywheel UPS systems are more efficient than traditional battery-based UPS. The company estimates that if the entire data center industry went to flywheel UPS, they could save $180 million a year.
The major concern of users with flywheels is the ride-through time, which is about 15 seconds. With batteries, the ride-through time all depends on how long the string of batteries is. Active Power responds that good generator maintenance can ensure that 15 seconds is plenty of time for ride-through time before the generators kick in.

data center cooling
Jack Pouchet, the director of energy initiatives for Emerson Network Power, is calling for a new metric measuring a data center’s water use as compared to its productivity (measured in Emerson’s own Compute Units per Second).
In a column in Environmental Leader, Pouchet writes that water could be “the next oil,” meaning that the availability of water is often difficult for many in the world, especially clean drinking water in developing nations. Pouchet suggests that the data center industry should be more cognizant of the water it’s using to cool IT equipment, and adding a water use metric to the current Power Usage Effectiveness (PUE) metric — which compares facility energy use to IT energy use — is a good start.
From Pouchet’s column:
It is time for the data center industry to formulate a Water Systems Productivity metric (WSP). Take useful work or even a proxy for useful work, such as the proposed Compute Units Per Second, and divide that by the amount of water used during the period. Water may be measured in units, with 1 unit equal to an acre-foot. However, gallons/liters is also acceptable.
This WSP metric would ideally be reported monthly with your other metrics. Once we start to measure and report water utilization, we will quickly realize that simply flowing more cooling water in order to “economize” may not always be the best answer. Now we will be able to have a meaningful tool to determine the ideal mix between dry-coolers, CW plants and evaporative cooling towers compared to the increased energy used with alternative solutions.

data center cooling,
Airside economizers,
Variable frequency drive (VFD) fans
Major data center colocation company Equinix scored an energy award from the Silicon Valley Leadership Group this week for the energy-efficient design its data centers.
Equinix has received almost $1 million in rebates from the city of Santa Clara for the energy efficiency measures, which include using airside economizers and variable frequency drive (VFD) fans in their data center infrastructure equipment.
The company estimates that the airside economizers save $300,000 per year and the variable speed fans save $51,000 per year. See “Data center air-conditioning fans blow cost savings your way” and “Data center cooling: airside and waterside economizers” for more information on these cost-saving data center technologies.
