      Carbon tax could whack data centers A carbon tax is inevitable, several speakers and panelists said at the Uptime Institute IT Symposium this week. Data centers that don't plan for it could get whacked with millions of dollars in additional operating costs per year -- and it could happen sooner than most people might think. "There will be a price for carbon, in spite of the nasty, messy politics in Washington," said Jonathan Koomey, a data center energy efficiency researcher, consulting professor with Stanford University and project scientist at Lawrence Berkeley National Laboratory. It is impossible to meet government mandated carbon reduction targets without one, he says. (Read Full Article)

      Fans: The new power hogs in the data center IBM fellow Roger Schmidt thinks that the energy efficiency benefits of using water based cooling could win over data center managers as increasing energy densities in server racks push the room-based cooling systems to the limit. While energy efficiency gains in processors have slowed the growth in energy density, the trend is still moving upwards. As energy densities rise, so does the volume of chilled air required to keep the equipment cool. More fans may be added and the fans may need to run faster to get sufficient air flow to keep equipment cool. (Read Full Article)

      Twitter Avoids Critical Upgrade to avoid outage during iran elections Worst. Timing. Ever. That was one of the many criticisms of a planned hour-long Twitter network upgrade, smack-dab in the midst of unprecedented demonstrations in Iran. The downtime was initially scheduled for tonight U.S. time. That would be morning or mid-day in Tehran. "However, our network partners at NTT America recognize the role Twitter is currently playing as an important communication tool in Iran," notes a recent Twitter blog post. "Tonight's planned maintenance has been rescheduled to tomorrow between 2-3p PST (1:30a in Iran)." Twitter has emerged as an important communication tool in Iran for those challenging the claim that Iranian president Ahmadinejad won re-election in a landslide, despite many indications that one of his opponents had much stronger popular support.
