ZDnet published information earlier today about a recent survey of 136 CIOs and IT managers conducted by Tecala in which participants were asked about top IT priorities. Of those surveyed, nearly all of the respondents said that virtualization and cloud computing rank at the top of their list. Another major consideration that has been at […]

New Green Server Competitor Emerging?

There has been a decent amount of chatter on all the media channels over some of Facebook’s efforts to move forward with innovative technology. The other day I wrote about its new “green” European data center based in Sweden. In addition, at the recent Open Compute Project Summit, Facebook announced its intention to contribute to greater standardization […]

Facebook’s “Green” European Data Center

As power consumption eats away at the environment and company budgets, many organizations constantly look for ways that they can harness renewable energy to cut down costs and improve their image with regard to the environment. Facebook’s first data center in Europe, based in Lulea, Sweden, is a good example of the possibilities of this:

Graph 500, Green500, HPCC, and SPEC: Alternative benchmarks for high-performance computing

Supercomputers have become a vital part of almost any innovative project undertaken by collaborative teams in the developed world. Server clusters can be found anywhere from the offices of small businesses to compartments in U.S. Navy submarines. So which are the fastest supercomputers on earth? The usual measurement for high-performance computer (HPC) clusters is the […]

China builds the world’s fastest supercomputer

After almost a year-long run, the Jaguar supercomputer at Oak Ridge National Laboratory in Tennessee has relinquished its title as the world’s fastest computer. This honor now belongs to the Tianhe-1A supercomputer located in the National Supercomputing Center in Tianjin, China. Tianhe-1A is expected to officially become the leader of the TOP500.org list of the […]

PUE can be a misleading energy-efficiency standard

The Power Usage Effectiveness (PUE) standard is one of the leading benchmarks for measuring energy efficiency in a data center. But there are some situations where an energy-efficient change to a data center will actually register as more wasteful by the PUE. For this reason, it’s important to know the gaps in the PUE metric. […]

Cooling Servers Under Oil

Micheal Feldman of HPCwire has written an interesting article about a startup company called Green Revolution Cooling (GRC) that has a competitive and innovative product in the server cooling market. GRC has developed a server rack that lies horizontally on the floor and is filled with an oil-based cooling fluid. Any server that is built […]

Cashews, Datacenters and Imperial Pints

When I was a kid, there was a t.v. show called Beyond 2000. It showcased cutting edge technology that was supposed to change the way we worked and lived. I guess, at the time, the siren song of the millennium still held its allure. Then we got American Idol and it all went downhill. I […]

PUE for data centers – updated measurement of energy efficiency

On our sister blog, ServerProblemsSolved.com, I’ve published some thoughts about the updated data center efficiency metric called PUE, short for Power Usage Effectiveness. If you are responsible for a data center or are interested in green IT, make sure to read as well the white paper put out by the Green Grid that details the updates that […]

Server rooms get hotter in Zurich

IBM’s new data center offers bold new ideas about how to cool servers. It has long been taken for granted that the best way to control the temperature in a server room was to keep it as cool as possible by blowing out the heat generated by processors inside the servers with chassis fans. IBM’s […]
