Thank you for the update.I've followed this and using NFSv3 procedure: https://library.netapp.com/ecmdocs/ECMLP2573777/html/frameset.html
these commands have the same output as well:
~ # esxcfg-advcfg -s 1 /DataMover/HardwareAcceleratedInit
Value of HardwareAcceleratedInit is 1
~ # esxcfg-advcfg -s 1 /DataMover/HardwareAcceleratedMove
Value of HardwareAcceleratedMove is 1
still hardware acceleration: not supported.
when cloning an offline guest from an SSD aggregate / volume on a FAS8080EX it takes a long time to complete on vSphere version 7. Doing the same procedure on vShpere 6.7 it is done in an instant.
Since this is a test environment I will drop it now and continue with my work vSphere 6.7
