There are servers and storage arrays that have a front that is nothing but hot-swap hard drive bays (plugged into backplanes), and they've been doing front-to-back cooling since day one. Maybe the router vendors need to buy a Dell, open the case, and take a look.
The backplane for a sata disk array is 8 wires per drive plus a common power bus.
Server vendors managed cooling just fine for years with 80 pin SCA connectors. Hard drives are also harder to cool, as they are a solid block, filling the space, unlike a card of chips. I'm not saying the problems are the same, but I am saying that a backplane making cooling "hard" is not a good excuse, especially when the small empty chassis costs $10K+. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
