Within Nutanix we have Replication Factor (How many data copies are written in the cluster) and Redundancy Factor (how many nodes/disks can go offline). Both can have a value of 2 and 3. What is what is explained here: Blog Post.

So, when we have a larger cluster, we always recommend using RF3 (Redundancy Factor 3) as the risk is higher that you have multiple nodes/disks go offline at the same time.

During trainings and onsite customer work I often get the question, "what will happen if multiple nodes go offline in Redundancy Factor 2?" In this blog post I will explain different scenarios and their behaviors.
