Nutanix Objects, part of Nutanix Unified Storage (NUS), provides S3-compatible object storage and is deployed as a set of Object Store Service VMs on a Nutanix cluster running AHV (or ESXi). The minimum number of nodes required for an Objects deployment ensures high availability and fault tolerance.

Analysis of Options:

Option A (1): Incorrect. A single-node cluster does not meet the minimum requirements for Nutanix Objects, as it cannot provide the necessary fault tolerance and high availability. Objects requires at least three nodes to distribute Object Store Service VMs and ensure data redundancy.

Option B (2): Incorrect. A two-node cluster also does not meet the minimum requirements for Objects. Nutanix requires at least three nodes to ensure that the Object Store Service VMs can be distributed across nodes and maintain availability in case of a node failure.

Option C (3): Correct. Nutanix Objects requires a minimum of three AHV nodes in a cluster to deploy and operate. This ensures that the Object Store Service VMs (typically three or more) can be distributed across nodes, providing high availability and fault tolerance. A three-node cluster is the minimum configuration for Objects to ensure data redundancy and resilience.

Option D (5): Incorrect. While a five-node cluster can certainly support Objects, it exceeds the minimum requirement. Nutanix specifies that three nodes are sufficient for a basic Objects deployment, making five nodes unnecessary for the minimum requirement.

Why Option C?

Nutanix Objects requires at least three nodes to ensure high availability, fault tolerance, and data redundancy. This allows the Object Store Service VMs to be distributed across nodes, ensuring that the service remains available even if a node fails. Three nodes is the minimum cluster size specified by Nutanix for deploying Objects.
