This may sound like a really simple question and I apologies if it's been answered elsewhere but I just can't find it

Is it possible, and how do I calculate the amount of usable space I would have on a Three node cluster with 5.4TB usable space per node using Virtual San? (3 x 5.4TB - 16.2TB)

Hello!
With StarWind Virtual SAN, you can create a device on one node and replicate it to partner nodes. Each device can be replicated to two other nodes (active-active replication). It means that you will have 3 copies of data on 3 nodes. So you will use 5.4 TB on each node and the usable capacity will be 5.4 TB.
