multiple storage policy after adding nodes

[mutthu]

We have a 2 -NODE vSAN cluster with a RAID1 storage policy. We plan to add three more nodes in the cluster with the same capacity. Will we have RAID1 and RAID5 storage policies once we complete adding the rest of the three nodes?

@mutthu, Storage policies are governed by vCenter - this can create any policy with any rules, it will show any datastores that are compatible with a policy e.g. you can create an FTT=1,FTM=RAID5 policy now and it will show the current vsanDatastore as incompatible, but when you have a minimum of 4 All-Flash nodes (and vSAN Advanced or higher licensing) it will show as compatible.

If I understood correctly, both RAID1 and RAID5 will be using the raw capacity, and used based will depend on which policy we assign to how many VMs.

@mutthu, Yes.
