Hybrid Linked Mode links your VMware Cloud on Dell EMC vCenter Server instance with an on-premises vCenter Single Sign-On domain. You can configure the Hybrid Linked Mode between VMware Cloud on Dell EMC SDDC and on-premises SDDC either directly or through vCenter Cloud Gateway to manage both the SDDCs in a single user interface. This can also be used to support VM migration across these SDDCs.
Before you can use Hybrid Linked Mode with VMware Cloud on Dell EMC, you must configure your on-premises vCenter to enable single sign-on. For more information, see vSphere Authentication with vCenter Single Sign-On.
If you link your cloud vCenter Server to a domain that contains multiple vCenter Server instances linked using Enhanced Linked Mode, all those instances are linked to your VMware Cloud on Dell EMC SDDC.
