SOLVED: If anyone meet the same issue as mine do the following: add the line below into your /etc/vmware/passthru.map file: # INTEL SUNRISE AHCI PASSTHRU8086 a102 d3d0 false Save file and restart ESXi.  This solution fully works on ESXi 6.7U2 on Poweredge T30.
Hello, I’ve just purchased Poweredge T30 server.  Inserted NVME and 4 SATA drives and installed ESXI 6.7 on SSD. Now I want to passthrough my SATA drives to VM, but unfortunately ESXI doesn’t allow me to passthrough SATA controller (I even don’t see it in the devices list).  I switched SATA to AHCI mode in BIOS, but still no luck. All SATA drives are operational, double checked them. BIOS sees them as well as ESXI does. Am I missing something? Is there any limitations in embedded SATA controller? Should I buy external SATA controller which supports passthrough? If yes, what kind of model you’d suggest, gents?
