Similar experience here, but the conversation went on far too long and ultimately lost Arista the deal. There was a ridiculous amount of insistence that we would have to carry a "stock of Arista optics", but every attempt to clarify exactly what that meant (how many, what they would cost etc) failed to get a straight answer.

It's 2016 and stupid conversations about vendor optics waste time and destroy deals.

The slight difference here is that pretty much the first thing we said to Arista was that transceivers were out of the question unless they could price them reasonably** (they chose not to). On this particular deal we were probably only talking about 500 SR 10G transceivers.

We've had similar conversations with Extreme, Brocade, Solarflare and Juniper, all of whom are quite happy with us running our own parts. Solarflare even certified our parts and put them on their website (

Doesn't surprise me, and I'm sure if we'd pushed for another week we could have got to this position. Unfortunately for Arista, there was another vendor quite happy to get the deal done faster and without all the BS so we voted with our feet.

Clearly, mileage will vary on this one.


** in this context, "reasonably" means no more than _double_ what I currently buy at.
