Grundsätzlich hat sich die Unterstützung mit 6.5 verbessert. Zumindest 512E werden "Direct-Attached" unterstützt.

Zu 512, 512E (512 Logisch und 4K Physisch) und 4K (logisch und Nativ) HDD's:
Do current GA versions of vSphere and VSAN support 4K Native drives?
No. 4K Native drives are not supported in current GA releases of vSphere and vSAN.
Which version of vSphere and vSAN support 512e drives?
vSphere 6.5 and vSAN 6.5 and later support 512e drives as direct attached drives. vSphere & vSAN will expose 512n to Guest OS.
VMFS 6.0 is required for 512e drive support starting with vSphere 6.5.
Prior to version 6.5, direct attached drives which expose 512e to vSphere and vSAN are not supported (see exception below) due to potential performance issues when using these drives. For more information, see the Impact/Risks section.
Exception: vSphere 6.0 and newer versions support Physical Mode RDMs mapped to direct attached 512e drives.
What if 512e drives are behind a compatible RAID controller and the RAID controller is exposing the 512n drives to vSphere?
vSphere supports this configuration as long as the RAID controller is exposing the 512e drives as 512n format drives to vSphere. The RAID controller must also be listed in the vSphere compatibility guide. Consult your RAID controller vendor to check your configuration and ensure it will not have a negative performance impact on the workloads you want to run.
