A company uses a Nutanix 3-node cluster environment.

To support a new RF3 container, the effective capacity of the Nutanix cluster must be at least three times the size of the data that needs to be stored on it3. This is because RF3 means that each data block is replicated three times across different nodes or blocks for fault tolerance3.

This is because if you have 4 TiB of effective capacity with RF2 (which means each data block is replicated twice), then you need 9 TiB of effective capacity with RF3 (which means each data block is replicated three times).
