1. Introduction: Why Service Central Matters

Nutanix Central is a unified management portal that consolidates and simplifies the oversight of multiple Prism Central (PC) instances, spanning datacenters, geographies, and tenants. For organizations managing complex environments, Service Central is the key to streamlined operations, consistency, and scalable governance.

2. Prerequisites and Planning

  3. Repeat for each site.
  4. Group PCs by site, tenant, or function as needed.

B. Enabling SSO/AD Integration

  1. Navigate to Settings > Authentication.
  2. Select Active Directory or LDAP.
  3. Provide directory server details, bind DN, and credentials.
  4. Map roles to AD groups (e.g., Admins, Operators, Auditors).

C. ServiceNow Integration

  1. Under Integrations, select ServiceNow.
  2. Provide ServiceNow instance URL, credentials, and mapping fields.
  3. Configure workflows for ticket automation, event ingestion, and reporting.

8. Automation and Scripting Examples

A. API: Registering a Prism Central Instance

curl -X POST "https://<service-central>/api/v1/prism-central/register" \
  -H "Content-Type: application/json" \
  -d '{"fqdn":"pc.sitea.corp","username":"admin","password":"<pwd>"}'

B. PowerShell: Bulk Add Prism Centrals

$pcs = @("pc1.domain.com","pc2.domain.com")
foreach ($pc in $pcs) {
  Invoke-RestMethod -Uri "https://servicecentral/api/v1/prism-central/register" `
    -Method Post `
    -Body @{fqdn=$pc; username="admin"; password="securepwd"} | Out-Null
}

9. Monitoring, Alerting, and Reporting

Sample CLI:

curl -u admin:pwd https://<service-central>/api/v1/alerts

10. Migration Playbook: Onboarding Legacy Instances

Pre-Migration Assessment

Step-by-Step Migration Process

  1. Network Prep: Ensure L3 connectivity and DNS resolution between legacy PCs and Service Central.
  2. Registration:
    • Log in to Service Central, select “Add Prism Central”.
    • Enter details for each legacy instance.
  3. Policy Mapping: Review current RBAC, security, and monitoring policies. Adjust for central management if necessary.
  4. Test Integration: Validate connectivity, inventory sync, and alerting from each legacy PC.
  5. Stakeholder Review: Confirm new workflows and delegated access with IT and business units.
  6. Cutover: Transition active management to Service Central.
  7. Decommission Legacy Management Tools: After a stable transition period, remove or archive old management utilities.

Rollback Plan

Migration Automation (Sample Script):

# Demostration-API example
for pc in $(cat pc_list.txt); do
  curl -X POST "https://servicecentral/api/v1/prism-central/register" -d "{\"fqdn\": \"$pc\", \"username\": \"admin\", \"password\": \"***\"}"
done

Pro Tip:

Pilot migration with a non-critical site before full-scale rollout to identify and address any unforeseen challenges.
