Trying to talk my company out of doing "white box" networking. Look for some ideas

So my company is seriously considering buying white box hardware and going with a cheap switching os vendor, the one they talked to is Cumulus, but I think they're looking for a few others.

Our team is really disgruntled, because we feel non technical people are making technical decisions, and then we're going to be stuck with this mess.

I seriously went into the Cumulus demo with an open mind, but came out of it knowing this will be a huge disaster.

We are a Cisco shop, and always have been. We know Cisco, like many of you here do. They want to get rid of a high performance proven product that is very well known, well understood, and well supported, in exchange for something that's just cheaper. That none of us have any experience with.

The worst part is this feels like it has momentum behind it, like the decision is already made. It's like a nightmare. I talked to a few members of our team, and they all feel the same way I do. The whole OS is based on Linux, which none of us have ever touched. I feel like we'll suddenly have an alien os that is nothing like normal network vendors. I would even happily accept Juniper or Arista instead of this. At least they'd be similar enough to Cisco that we could get by.

I just see this as a marketing fad, and their being swayed by the low cost, but you get what you pay for! You pay 1/3rd and get 1/3rd the quality. Hello?

Anyone else going through this?

Thanks!
