    Study Notes

    Management Domain Components

    • VMware Cloud Foundation supports Active Directory (AD) and OpenLDAP for identity sources. At least two domain controllers are needed for directory service availability, in different physical locations.
    • DNS servers must be highly available. Failure in name resolution prevents VMware Cloud Foundation components from communicating and hinders workload domain creation/operation.
    • NTP (Network Time Protocol) is critical for authentication, especially for vCenter Single Sign-On which is time-sensitive. Multiple NTP servers provide redundancy against drift or outages for accurate time synchronization.
    • VMware Cloud Foundation uses static IP pools or DHCP to provision IP addresses for NSX tunnel endpoints on ESXi hosts. DHCP servers are required on the VLAN assigned to tunnel endpoints to reassign IP addresses to VMkernel ports when ESXi hosts are rebooted.
    • Certificate Authority (CA) is required for replacing VMCA-signed certificates during setup.

    SDDC Manager Backup and Restore

    • Maintain up-to-date SDDC Manager backups to ensure consistency with the current VCF state.
    • Consider using SFTP for backup locations as external alternatives to the built-in SFTP server. This approach improves protection against failures by decoupling the backup operation from the SDDC Manager.
    • Configure hourly or weekly automatic backups; schedule backups depending on the frequency of environment changes. Unscheduled backups are available for significant environmental changes to avoid data loss.

    NSX Backup and Restore

    • NSX Manager backups occur every hour for each node in the management cluster by default or manually.
    • Backups can be initiated from the NSX Manager UI.
    • NSX Manager backups inherit the SFTP settings from the SDDC Manager.

    Native vSphere Availability Options

    • vCenter deploys the management domain with vSphere HA configured using best practices; this includes host failure response, host isolation, and datastore configurations. The datastore with permanent device loss and paths down should be disabled.
    • Powering off versus shutting down VMs is different.
    • Hosts can be configured for a tolerance in admission control settings depending on the size and needs of the deployments. Adjustments to Performance degradation tolerances may be required if adding more hosts.
    • vSphere HA restarts VMs if hosts fail and contributes to service availability for most issues. VMware tools are monitored.
    • vSphere HA resets the VM if VMware tools heartbeats fail for over 50 seconds to restore services.

    vSphere Distributed Switch Backup and Restore

    • Export the vSphere Distributed Switch (VDS) configuration whenever changes are made. Exporting ensures that VDS configurations are restored if vCenter fails.
    • Keeping a separate backup of the VDS configuration is best practice.

    Additional Considerations

    • An external SFTP server is considered a best practice because it decouples the NSX backups from the SDDC Manager backups, maintaining protection even if SDDC Manager fails.
    • Critical infrastructure components like NTP, DNS, and Active Directory (AD) must be configured correctly for proper VMware Cloud Foundation operation.
