Dualport U.2 "breakout"-cable?

[efschu3]

I have a PM1733 U.2 lying around, and I’m thinking about using it for a “big-little” server project. I haven’t found a “Y-cable” or “breakout cable” yet. Where can you even get those? one drive, two hosts via NVMe U.2?

It should exist, as this one exist:

I skimmed the PM1733 datasheet, seems like it's not a dual port drive (but maybe you got a special model or it can be switched to 2x2 lanes.) In any case sharing one physical drive between two hosts without some storage appliance layer in between is non-trivial and almost certainly a bad idea.

Oh, I know that.

I'm just looking for a single cable instead of those endless Adapter "snake" builds. (and yes, IT will Always become 2x/2x)
