1. Introduction to Nutanix DR

Disaster recovery ensures that applications and data remain available, even after catastrophic events. Nutanix delivers integrated DR features across all deployment models, minimizing recovery time objectives (RTOs) and recovery point objectives (RPOs).

Nutanix DR is designed to be hypervisor-agnostic but delivers the richest integration with AHV. It enables rapid, policy-driven failover, automation, and seamless orchestration.

2. Core Concepts and Terminology

TermDescription
RPORecovery Point Objective: How much data loss is acceptable
RTORecovery Time Objective: How quickly workloads must be recovered
DR RunbookPre-defined sequence of failover steps
Metro AvailabilitySynchronous, zero RPO replication across sites
NearSyncSub-minute, asynchronous replication for critical workloads
Nutanix LeapSaaS-based DR orchestration and runbook automation
Consistency GroupGroup of VMs/data to be replicated as a single unit

3. Nutanix DR Solution Portfolio

Nutanix offers a range of DR features, all managed through Prism Central and Leap.

NearSync

Metro Availability

Native Snapshots and Replication

4. Architecture Overview

Nutanix DR leverages a combination of local clusters, remote DR clusters, and a SaaS control plane (Leap).

5. Pre-Requisites and Planning

6. Deployment Models: On-Prem, Hybrid, Multi-Cloud

Nutanix DR supports a variety of architectures:

7. Configuring Nutanix Leap

Leap offers policy-based orchestration for DR. Below is a typical setup flow.

Step 1: Access Leap

  1. Log in to Prism Central.
  2. Navigate to Data Protection & DR > Leap.

Step 2: Register Sites

Step 3: Create Protection Plans

Step 4: Author Runbooks

Sample CLI to Query DR Plans:

ncli protection-domain list
ncli protection-domain.get name=<ProtectionDomain>

8. NearSync: Sub-Minute RPO Protection

NearSync allows you to protect critical workloads with minimal data loss.

Configuration Steps:

  1. Enable NearSync on both clusters.
  2. Select VMs/consistency groups for NearSync protection.
  3. Set schedule (default: every 20 seconds).

CLI Example:

ncli protection-domain.create name=Finance-NS type=NearSync
ncli pd-schedule.create pd-name=Finance-NS schedule-type=every_x_minute

9. Metro Availability for Zero RPO

Metro Availability is ideal for environments needing zero data loss and active-active clusters.

Requirements:

Enabling Metro Availability:

  1. In Prism Central, go to Data Protection > Metro Availability.
  2. Pair clusters and designate Metro Availability-enabled storage containers.
  3. Enable VM affinity rules for site failover.

CLI Snippet:

ncli container edit name=<ContainerName> enable-metro-availability=true

10. Failover, Failback, and DR Testing Workflows

Sample Failover Command (CLI):

11. Compliance, Reporting, and Monitoring

API Example for Reporting:

GET /leap/api/v1/reports
Authorization: Bearer <token>

12. Advanced CLI/API Automation

Nutanix exposes robust APIs for automating DR.

Example: Create DR Plan via API

curl -k -X POST "https://<prism_central>:9440/leap/api/v1/plans" \
  -H "Content-Type: application/json" \
  -d '{
        "name": "Critical-DR-Plan",
        "protected_vms": ["VM1", "VM2"],
        "recovery_point_objective": 60,
        "runbook_steps": ["network", "poweron", "validation"]
      }'

Bulk Failover Script (Python)

import requests

def trigger_failover(plan_id, token):
    url = f"https://<prism_central>:9440/leap/api/v1/failover/{plan_id}"
    headers = {'Authorization': f'Bearer {token}'}
    r = requests.post(url, headers=headers)
    return r.status_code, r.json()
