For RAID-5, a minimum of 4 hosts are required; for RAID-6, a minimum of 6 hosts are required.

Hello SyedHasan2701

As @IT_pilot stated - you won't be able to use RAID5 for FTT=1 here as you only have 3 nodes, only RAID1. Additionally RAID5/6 requires All-Flash configuration. Is there a particular reason you are considering using ROBO licensing as opposed to normal vSAN Standard/Advanced/Enterprise licensing? From speaking with people that have compared cost of these, ROBO seems to work out as more expensive (though by all means do assess and compare the costs of these yourself as this may vary).

Also, there is no such thing as "vSAN ROBO Advanced vCenter Foundations" - this is just vCenter Foundations.
