Video: Panel Discussion – Has the PUE Issue Already Been Solved for the Datacenter?

Has the issue of optimized PUE largely been solved already for large datacenters? In this presentation, you’ll hear from the following individuals in a panel discussion moderated by James Hamilton of Amazon. Chris Malone, Google Rob Coupland, Telecity Group Ian Bitterlin, Ark Continuity Ltd Brian Waddell, Norman Disney & Young Recorded at the 2011 Data […]

The Green Grid juices PUE datacenter measure

The Green Grid has recently updated its PUE metric (Power Usage Effectiveness) that attempts to wrangle some of the uncertainty in the prior definition of the measure. Ted Samson has a nice analysis One of the greatest strengths of the PUE metric, the industry standard for measuring data center energy efficiency, is its simplicity: Calculate […]

Google tips for getting to a PUE of 1.5

Ted Samson writes about comments that Google Green Energy Czar Bill Weihl made at last weeks’ GreenNet 2010 conference in San Francisco. The most interesting tip Weihl shared pertained to power infrastructure. Whereas most companies use large PDUs (power distribution units) to provide backup power for their data center hardware, Google instead equips each server […]

New international agreement on PUE may get momentum going

Enterprise IT Planet’s Green blog has a post up this morning about an international agreement reached over the weekend that may help build momentum for a common vocabulary when it comes to measuring datacenter efficiency Over the weekend, news emerged of an international agreement to establish data center energy efficiency. The agreement is between The […]

Interview: NSU to Boost Research with “Megalodon” IBM Supercomputer


“The team at the Graduate School of Computer and Information Sciences wanted to give the computer a nickname – a name that would not only convey the super computer’s enormity in terms of size; but a name that would definitively link the super computer to NSU. Our mascot is the “shark” and the Megalodon, is the largest prehistoric shark known to man.”

Interview: Calyos 2-Phase Cooling for Electronic Components in HPC


“Thanks to the latent heat physical properties and its pumpless capillary structure, Calyos advanced 2-Phase cooling solutions will help the HPC world by reducing the cooling costs while significantly increasing power densities.”

NREL’s Peregrine: HP’s Warm Water Cooled HPC Platform


Nicholas Dube from HP presented this talk at the Adaptive Computing booth at SC13. “The ESIF data center is designed to achieve an annualized average power usage effectiveness (PUE) rating of 1.06 or better. Going beyond traditional PUE measurements, the NREL HPC Data Center is using warm-water liquid cooling for its high-power computer components, then capturing and reusing that waste heat as the primary heat source in the ESIF offices and laboratory space.”

New NREL Datacenter Tops in Petascale Energy Efficiency

One of the missions of the National Renewable Energy Laboratory (NREL) is to advance renewable energy research. So when it came time to build their new HPC datacenter, they decided to “walk the talk” and push the limits of energy-efficient supercomputing. Well, so far, so good. With the first petascale system to use warm-water liquid […]

NETL's New SGI Super Sets the Bar for Energy Efficiency

The Office of Fossil Energy’s National Energy Technology Laboratory (NETL) has deployed a new SGI ICE Cube Air modular data center with extreme energy efficiency. Currently ranked at #55 on the TOP500, the system is being used for energy research at various scales ranging from molecules, to devices, to entire power plants and natural fuel […]
