Summary
This document describes the management domain in VMware Cloud Foundation (VCF), covering various components like DNS, NTP, DHCP, and certificate authority, as well as backup and restoration procedures for SDDC Manager and NSX. It also discusses vSAN storage policies and high availability settings. It includes questions and diagrams.

**Management Domain (all management components) Availability and Backup -- VCFDCM52** Business Continuity, High Availability -- resilient infrastructure Directory Services DNS NTP DHCP Certificate Authority Border Gateway Protocol (BGP) Peers A screenshot of a computer Description automatically generated **SDDC Manager Backup and Restore Process (brains of operation)** - An external SFTP server is a **prerequisite for restoring SDDC Manager** file-based backups. - An external SFTP server provides better protection against failures because it **decouples NSX backups from SDDC Manager backups**. - An external SFTP server provides better protection against failures because it means that the failed SDDC Manager does not take down the SDDC Manager backups with it. **Restoring SDDC Manager Backups** 1. Use the vSphere Client to deploy a NEW SDDC Manager OVA Management Cluster 2. Take a snapshot of the newly deployed SDDC Manager 3. Power on SDDC Manager and use the CLI to restore the SDDC Manager backup to the newly deployed VM ![A screenshot of a computer program Description automatically generated](media/image2.png) **NSX Backup and Restore Process** NSX Backups INHERIT the SFTP backup settings of SDDC Manager - NSX Manager backs up each node of the NSX management cluster every HOUR by default - 4 IP addresses, 3 nodes need to be protected - Backups can also be manually initiated from the NSX Manager UI at - - Big changes, manually kick this off 1. Power off any failed NSX Manager appliances from the old NSX Management cluster 2. Deploy one new NSX Manager appliance using the same IP and FQDN as the previous node 3. Log into the NSX Manager UI at 4. Make the new NSX Manager Active 5. Navigate to the Backup & Restore page 6. Configure the SFTP server details used by the previous NSX Manager node 7. In the list of NSX Manager backups, select the desired backup & click RESTORE 8. Deploy additional NSX Manager nodes for the newly restored cluster - Host failure response: restart VMs - Response for Host Isolation: Power off and Restart VMs - Datastore with Permanent Device Loss: Disabled (PDL) - Datastore with All Paths Down: Disabled - VM Monitoring: VM Monitoring Only **Using vSAN Storage Policies** - You can provide additionally redundancy to domain components using vSAN storage policies - Default Storage Policy provides resilience against a single failure - You can configure higher levels of failures to tolerate - Tolerate 2 failures - Expand the domain to a minimum of 5 hosts for Raid-1 - Expand the domain to a minimum of 6 hosts for Raid-6 (erasure coding) - Tolerate 3 failures - Expand the domain to a minimum of 7 hosts (Only Raid-1 supported) A screenshot of a computer error Description automatically generated ![](media/image5.png) ![](media/image7.png)
