You like Arista for price, density, etc.? Then factor in the cost (OpEx & CapEx) of vendor-specific optics and see if they still make sense. Don't just look at the per-port cost of the blade. See, it's a simple business decision for you too.
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
