To prepare the clustered Workspace ONE Access instance and the VMware Aria Suite products for failover, you update the DNS and NTP settings on each protected virtual machine.

Name Resolution for Multiple VMware Cloud Foundation Instances

In an environment with multiple VMware Cloud Foundation instances, multiple DNS servers are available across the instances, providing higher DNS availability and resilience. When DNS servers in the protected instance are unavailable, DNS servers in the recovery instance will be used.

Design Implication

SPR-DNS-NET-001

In an environment with multiple VMware Cloud Foundation instances, configure the DNS settings for each protected component to use the DNS servers across all VMware Cloud Foundation instances.

Each protected component can resolve DNS from DNS servers during a planned migration or disaster recovery between VMware Cloud Foundation instances.

As you scale from a single VMware Cloud Foundation instance to multiple VMware Cloud Foundation instances, you must update the DNS settings on each protected component.

Time Synchronization for Multiple VMware Cloud Foundation Instances

In an environment with multiple VMware Cloud Foundation instances, multiple NTP servers are available across the VMware Cloud Foundation instances, providing higher NTP availability and resilience. When NTP servers in the protected instance are unavailable, NTP servers in the recovery instance will be used.
