Ensure that you have fulfilled the following prerequisites before configuring Hybrid Linked Mode.
Common Prerequisites
- Configure an uplink connectivity between VMware Cloud on Dell EMC SDDC and your network. See Configure Uplink Connections.
- Ensure that VMware Cloud on Dell EMC network resolves to the SDDC hostnames that you have provided. See Configure DNS Forwarding for Management Network.
- Ensure that vCenter Management traffic is handled through your private network or through Internet. See Configure vCenter Settings.
- Ensure that your on-premises data center and your VMware Cloud on Dell EMC SDDC are synchronized to an NTP service or other authoritative time source. When using Hybrid Linked Mode, VMware Cloud on Dell EMC can tolerate a time skew of up to 10 minutes between the on-premises data center and the VMware Cloud on Dell EMC SDDC.
- The maximum latency between your VMware Cloud on Dell EMC SDDC and on-premises data center cannot exceed 100 msec roundtrip.
The following prerequisites apply when linking with the vCenter Cloud Gateway Appliance.
- Install the vCenter Cloud Gateway Appliance as described in Installing and Configuring the vCenter Cloud Gateway Appliance.
- Your on-premises environment is running vSphere 6.5 patch d or later.
- Ensure that the vCenter Cloud Gateway Appliance and your vCenter Server instances can reach each other over your network. Ensure that the following firewall ports are open.
