You got my point : I do care about per-port cost, but the actual cost is a composite of : - kit price - licences - optics - spare optics - power per port over expected run time - collocation space > Besides, what's wrong with using something (as Nick mentioned) like > FlexOptics programmable optics? Haven't tried it in Arista, but other > kit works fine. Programmable optics are fine, but then you'd have to keep your programming gear available and train your techniciens on it, or keep pre-coded spares for every locked manufacturers. It's probably fine in a pure DC environment with few locations and only one SFP+ type, but it's rapidly a total mess when you have to manage 40 channels for 3 module types over dozens of locations AND the added manufacturer specific pain-in-the-ass. -- Jérôme Nicolle +33 6 19 31 27 14
