Thanks for the great update!
It worked fine with the ESXi 7.0u2 and Transcend NVMe SSD.
Driver :
nvme-community-driver_1.0.1.0-2vmw.700.1.0.15843807-component-18290856.zip
Tested SSD :
Transcend PCIe SSD 220S TS2TMTE220S
* controller: Silicon Motion, VID:0x126f, PID:2262
Thanks for your precious work!
BTW, is there any hope to get back Thunderbolt ports usage?
