The great cooling debate and how Alcatel-Lucent changed the game.

Posted by Gary Dunlap on Friday, July 23, 2010, In : Temperature and Humidity 
I am scheduled to visit the Alcatel-Lucent facility in Plano . Texas next month to take a first hand look at their new modular server rack cooling system. Your first question is probably "Alacatel-Lucent makes a cooling system?!?" This longtime staple of the IT world and particularily the telecom industry decided to design and build their own cooling sytem. The primary reason behind this was frustration with the current state of computer room cooling. Alcatel has made a big investment in IP v...

To Contain or Not To Contain.....What's The Answer?

Posted by Gary Dunlap on Saturday, March 6, 2010, In : Temperature and Humidity 


The use of hot aisle/cold aisle configurations had been around for several years and the physics of it make sense - put the cold air in the front where the equipment breathes and put all the hot air in a separate aisle - but  in this traditional design in a high-density data center, up to 40% of the cool air is wasted. Hot and cold air mix over the top of racks and around the rows. So doesn't this seem like only part of the solution?
 
  The issue here is air mixing, if you mix hot and co...

Running Hotter Data Centers? Too Cool For School??

Posted by Gary Dunlap on Saturday, October 17, 2009, In : Temperature and Humidity 

In this recent article in "the Register" Intel is floating the concept of data centers being too cool and thus wasting power. See http://www.theregister.co.uk/2009/08/31/data_centers_run_too_cool/.

I believe that several things need to be researched before we make a mass exodus to 80 degree F+ server rooms. The article mentions warranties from manufacturuers that specifically become null and void if the equipment reaches certain temperature levels. Although Intel is raising the question , th...
