Cable or NVMe -> U.2 adapter issue. But I have 8 adapters and the odds that every.single.one is bad seems low. Easier to believe a wiring issue.This sounds like a cable problem to me, but I'd expect the oculink->8639
cable to work fine. I've seen some suggestions that oculink->8643 cables are directional, but that wouldn't make any sense for a 8639 cable.
Here's the link to the the 8643 cables I picked up. -> https://www.amazon.com/gp/product/B0773R3FB6
Here's the link to the version of the adapter IIRC is linked in this thread somewhere. -> https://www.amazon.com/gp/product/B01HR0PKJQ
Here's the other variant. -> https://www.amazon.com/gp/product/B07FMQPPRF
While there's no mention of the wiring spec those employ _there_, I found them w/some search effort that got me to this -> https://www.amazon.com/Micro-SATA-Cables-SFF-8643-Connector/dp/B0773R3L5V Which if you look at the description you see mention of sff9402 and refclk culmination at the very bottom with:
'For use with our High Speed Cable PN # RHS36-2583 Adapter Micro SATA Cables PN # SFF-1332-U2X4'
A search for that on pn linked back to the cable.
Correct; Intel plx card -> u.2 adapter.I mean, it's not like you're going to have the other end of 8639 on a card and try to wire it to oculink on an enclosure, right? Also, there's no other use for an oculink to 8639 cable that I can think of, so I'd expect them all be wired right for NVMe use.
Sure. That would be grand! Not at all cheap though. I ordered only 2 of these -> https://www.amazon.com/gp/product/B07CVMX4GV just to try since they aren't cheap.Do you have a link to 8639 cable that you're using? Maybe I could give it a try here and see if it works with any of my devices.
In an attempt to eliminate some other variables, I ordered some more variants of adapters and cables. e.g.:
nvme -> u.2 adapter : https://www.amazon.com/gp/product/B01HOWXAPI
'shotgun franken-kit': https://www.amazon.com/gp/product/B01LZHUJ8W
pcie x4 -> 8643: https://www.amazon.com/gp/product/B01LY9HRDB
nvme -> 8643 adapter: https://www.amazon.com/gp/product/B01LZREOF1
Those were _just_ delivered. I'll see if I can get _anything_ to work. The idea is to, at least, see if the 960/970 pros even work in the u.2 adapters using 'regular' pcie adapter-fu. If that works, then the sleds are validated and it confirms cabling.
I ended up having to email my question/request for clarity from icydoc. Their response thus far is:
"Thank you for your inquiry regarding the MB699VP-B and the card you are using. I have contacted engineering regarding your request and they should be able to provide additional information on the pinout we use on the MB699VP-B and the SFF-9402 specification.
I will let you know when they get back on this request."
Thanks for your assistance!
