Study Notes

Cluster Protect Configuration

  • Nutanix Cloud Clusters (NC2) on AWS utilize local NVMe storage, mitigating data loss risks from Availability Zone (AZ) failures or bare-metal node termination.

Protected Entities

  • VM configurations and snapshots (e.g., VM disks, volume groups)
  • Prism Central configuration data
  • Flow Network Security policies
  • Disaster Recovery (DR) configurations (protection policies, recovery plans, VM categories)
  • Data snapshots from EBS volumes attached to the cluster

AOS 6.8 or Later Enhancements

  • When using AOS 6.8 or later, virtual Trusted Platform Module (vTPM) enabled AHV UVMs can be protected and recovered, storing snapshots in an S3 bucket.

Cluster Protect Setup

  • Requires two Amazon S3 buckets: one for UVM and volume group data, and another for Prism Central configuration.
  • Requires AOS Ultimate or NCI Ultimate licensing tier.
  • Uses point-in-time backup feature in Prism Central UI for Prism Central configuration.

Prerequisites for Cluster Protect

  • AOS version 6.8 or higher
  • Prism Central Version pc.2024.1 or higher
  • AOS Ultimate or NCI Ultimate licensing tier
  • Separate subnets for UVMs and Prism Central/Multicloud Snapshot Technology (MST)

Limitations of Cluster Protect

  • Cluster Protect and protection policies cannot be used concurrently on the same cluster.
  • Protected clusters must reside in the same Availability Zone.
  • Clusters cannot be hibernated or terminated while protected by Cluster Protect.
  • Cannot be used with Flow Virtual Networking.
  • Recovered VDI clusters might consume more storage than initial.
  • Maximum of five clusters and 1000 entities (VMs/Volume Groups) can be protected.
  • Supported data sizes of up to 100 TB with a Multicloud Snapshot Technology
