[AusNOG] Switch installation in data centre racks - front facing, or rear facing?

[Peter Tiggerdine]

that would mean the concept of patch by exception does not require
patch panels and clearly even with that methodology it's used. Seems
like some crack smoking logic there. I bet 90% of most peoples access
layer has the same configuration on their switches.

I don't think scale has anything todo with it. Sounds more about
margin, the cost of RU space and how close to the wind most SP are
flying which, in-turns means paying engineers peanuts and doing
whatever to bring the revenue in.

Peter Tiggerdine
