    Ensuring that two vSAN disks (FTT=0) do not hit the same node/disk

    jancipra Lurker



      I have a situation that we need to provision two virtual disks (on vSAN datastore) for a VM, the disks will form an software RAID 1 in the VM (that is requirement of the application). So if I will provision the disks with FTT=1, I will have 4 copies of the data which is wasting of capacity. On the other hand, If I will provision the disks with FTT=0, I will be in risk that the disks will hit the same node/disk and make a SPOF.


      Is there some hidden parameter that will ensure that the two disks will be stored on different nodes in the vSAN cluster?


      Thank you for answer.
