Postman delivered my HGST NVMe today so I got a chance to try them, both appear to power up correctly, green LEDs and a brief flash of a yellow LED but neither are recognized in the BIOS or in ESXi.
I'll raise this with supermicro this week, see if they can provide any support.
Neither of you has per chance a non p3700 intel nvme ssd? ideally p366/3500 ?
- its quite interesting its a p3700 for both of you while the non intel works fine - maybe its an intel problem not a SM one...
I forgot I had some Samsung based m.2 format sticks I can pull out tomorrow to try, this will require swapping out the supermicro PCI card and replacing it with a Asus.
My logic based on S3700s failing and HGST Ultrstar HUSMR7696BDP3Y1 failing is this is more likely Supermicro or ESXi related.
well to totally wrap up this issue, supermicro support today confirmed to me they *ARE* able to reproduce this issue, but will not be fixing (i would understand a bit more if the p3700 wasnt such a relevant and popular drive, and still amoung the fastest with high WE):
I was able to reproduce the Intel P3700 U.2 NVME issue that you were seeing. Since Intel P3700 NVME is EOL, so we don't plan to debug and fix the issue. If you plan to use Intel NVME for your system, please consider Intel P4600 or the new Intel P4700 series.
I will go ahead close the ticket by the end of the day.

edit: on a side note, an something ive been wondering for awhile now, does a p4700 exist?? if not, than what is the current gen intel nvme drive with super high write endurance? (other than optane)
R.I.P p3700, one of the best nvme drives in the history of the world.
