The scalability of Nutanix Cloud Clusters (NC2) on AWS is a critical architectural consideration for high-growth environments. While earlier versions or specific regions might have different baseline limits, the maximum size for a single NC2 cluster on AWS is officially supported up to28 nodes. This limit is designed to balance the performance benefits of the Nutanix Distributed Storage Fabric (DSF) with the underlying AWS bare-metal infrastructure and networking constraints. Expanding a cluster to this size allows for significant workload consolidation and high availability within a single management domain. Administrators must ensure that their AWS account quotas and VPC subnet sizing are sufficient to accommodate the vCPU and IP address requirements associated with a 28-node deployment to prevent provisioning failures.
