In a cross-vCenter NSX environment, you can have multiple VMware vCenter servers, each of which must be paired with its own NSX Manager.

One NSX Manager is assigned the role of primary NSX Manager, and the others are assigned the role of secondary NSX Manager. The primary NSX Manager is used to deploy a universal controller cluster that provides the control plane for the cross-vCenter NSX environment. The secondary NSX Managers do not have their own controller clusters. The primary NSX Manager can create universal objects, such as universal logical switches. These objects are synchronized to the secondary NSX Managers by the NSX Universal Synchronization Service. You can view these objects from the secondary NSX Managers, but you cannot edit them there. You must use the primary NSX Manager to manage universal objects. The primary NSX Manager can be used to configure any of the secondary NSX Managers in the environment.

The following Universal objects are supported:
  • Universal LDR
  • Universal Transport Zone
  • Universal Logical Switch
  • Universal Firewall Rule
  • Universal Security Group
  • Universal IPSets
  • Universal Service
  • Universal Service Groups
  • Universal Segment Range
