Alex, Remember the Ascend MAX TNT and the sideways left-right airflow? The preferred method of deployment was three tall in a two post rack, mid mount. At the end of about the 10th row you could literally cook a steak and subsequently burn out the gear beyond that point. We fashioned our own dividers to keep airflow from forming a jet down the line via ACE hardware angle brackets that we cored to EIA screw spec and sheets of 1/4" plexiglass mounted between. Cheap as heck and worked like a champ. Airflow redirection can work. Building a plenum for this could be relatively cheap and easy with a small amount of sheet metal and a pair of tin sheers. Don't forget the warranty; I'd check for anything explicit around airflow. Let us know what you do, love the innovation.

The rock has turned over for a moment and I have crawled out. It is good to see the sunlight from time to time. Those who know me know my life has gotten away from networking and that sort of thing, and I am fully immersed in datacenter design and construction for IT type loads (blades, compute, disk, etc.). However, I am presented with the challenge of having to deal with some optical gear (Ciena stuff, mainly). My question: have the optical folks woken up and made things cool front to back, or are they still in to the bottom to top world? Comments and lambasting: go Thanks!
