Hi Nick,

Here are the RF3 requirements:

  • A cluster must have at least five nodes, blocks, racks for redundancy factor 3 to be enabled.
  • For guest VMs to tolerate the simultaneous failure of two nodes or drives in different blocks, the data must be stored on storage containers with replication factor 3.
  • Controller VM must be configured with enough memory to support redundancy factor 3.
