Hi,   Using DSM 7.0 with tinycore redpill running in ESXi 7 I can attach a VIRTUAL NVME device and it has detected using the simple edit of the "/etc.defaults/extensionPorts" file. Thank you for the tip. However, I can't use it as a cache (the final objective, as I put the VMDK in a SSD storage) because the SMART present incorrect data:   root@DSM:~# smartctl -a -d nvme /dev/nvme0 smartctl 6.5 (build date Feb 20 2021) [x86_64-linux-4.4.180+] (local build) Copyright (C) 2002-16
