FR_WolfmanOption: A

Answer A. vSAN needs direct access to the disks, if possible without RAID controller. If there is a RAID controller, it should be in passtru mode, or in the worst case, in RAID 0.

AlchotOption: A

A Use storage controllers in passthrough mode for best performance of vSAN. Storage controllers in RAID 0 mode require higher configuration and maintenance efforts compared to storage controllers in passthrough mode. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-479EB3F1-7F72-478A-9A5B-F05F3FA29308.html
