That'd be great if they could. We started using Arista 5 or 6 years ago at a small startup I was working for because Arista was the only vendor we could find who was comfortable giving us such an amazing amount of access to the inner workings of their high speed switches. Really enjoyed working with their gear and, when the occasional question came up, their engineers (top notch folks).

I've run Arista for 10 years now (since Arastra days), but I'm a lot more interested in whitebox switches running some sort of open networking software. The silicon designs are all coming from Broadcom/Intel/etc.

This is where stuff like Cumulus comes into play, and is a lot more excited than vendor lock-in on "open" technologies provided by Arista.
