[Wired] Researchers Visit the 19th Century, Bring Back Wireless Data Center

Researchers at Cornell University and Microsoft have cooked up a recipe for a wireless data center. That’s right, an entire data center that shuttles information among thousands of machines using not cables but thin air.

Their design throws out traditional switches and networking cables, but it also borrows from a very unusual source: the 19th century mathematician Arthur Cayley.

Interesting.... wireless allows for multiplexing for greater throughput if noise can be mitigated. It allows for more dense servers since inter-server communicaton can be easier since server A can communicate directly server B if close, else have other servers pass the communication through server C, D, ...

While it would require some serious location planning, this could be something very interesting to implement. It definitely could help with other areas like cooling. Just redesign the standard server layout so that the cpus are on the inside of the cylinder and then pump air downward into the center. VOILA - no more freezing large sections of floor and working on servers would no longer mean having cold air pumped up your pant leg or down the back of your shirt.

Some more thought-out data centers already arrange existing racks to create hot-cold channels. thumb.gif

Just place tarps to seperate the aisles to reduce air mixing to further improve HVAC efficency.

Besides, most data centers are unnecessarily cold anyways.

Too true. Both of our DCs are freezers. I hate going in there without a coat.

Even hot/cold rows are pretty inefficient. Being able to directly pump cold air into the middle of the rack would be get air used much more quickly.

You might want to check out increasing your temperatures: http://www.wired.com/wiredenterprise/2011/12/data-center-ice-age/

Up to 80F is recommended by ASHRAE... and that number is going up next year.

Would if I could, but that requires senior management to actually listen. Or the hosting company we use for our DR site.

Could this possibly lead to the data center being less secure though?

Not really. With a range as short as the 60GHz wireless offers, you'd have to be within ~30ft of the racks to even get a reliable signal. Then you'd have to break the encryption of whatever protocols they are using.

Question though: How healthy would this be to work in? That's going to be an awful lot of RF flying around in there...
