Nutanix clusters are resilient to a drive, node, block, and rack failures because they use redundancy factor 2 by default, allowing Nutanix clusters to self-heal2. Failure scenarios can be thought of in terms of fault domains, which are the physical or logical parts of a computing environment or location that are adversely affected when a device or service experiences an issue or outage3. There are four fault domains in a Nutanix cluster: Disk, Node, Block, and Rack4. Block and Rack are two options that are available for expanding the failure domain level of a cluster. Block fault tolerance is enabled by default and ensures that data is replicated across different blocks in a cluster5. Rack fault tolerance has to be configured manually and ensures that data is replicated across different racks in a cluster4.
