NSX Data Center for vSphere allows you to manage multiple environments from a single primary NSX Manager.

Benefits of Cross-vCenter NSX
NSX environments containing more than one vCenter Server system can be managed centrally.
How Cross-vCenter NSX Works
In a cross-vCenter NSX environment, you can have multiple 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.
Support Matrix for Services in Cross-vCenter NSX
A subset of NSX Data Center for vSphere services are available for universal synchronization in cross-vCenter NSX. Services that are not available for universal synchronization can be configured for use local to the NSX Manager.
Universal NSX Controller Cluster
Each cross-vCenter NSX environment has one universal controller cluster associated with the primary NSX Manager. Secondary NSX Managers do not have a controller cluster.
Universal Transport Zone
In a cross-vCenter NSX environment, there can be only one universal transport zone.
Universal Logical Switches
Universal logical switches allow layer 2 networks to span multiple sites.
Universal Logical (Distributed) Routers
Universal Logical (Distributed) Routers offer centralized administration and a routing configuration that can be customized at the universal logical router, cluster, or host level.
Universal Firewall Rules
Distributed Firewall in a cross-vCenter NSX environment allows centralized management of rules that apply to all vCenter Servers in your environment. It supports cross-vCenter vMotion which enables you to move workloads or virtual machines from one vCenter Server to another and seamlessly extends your software defined datacenter security.
Universal Network and Security Objects
You can create custom network and security objects to use in Distributed Firewall rules in the universal section.
Cross-vCenter NSX Topologies
You can deploy cross-vCenter NSX in a single physical site, or across multiple sites.
Modifying NSX Manager Roles
An NSX Manager can have roles, such as primary, secondary, standalone, or transit. Special synchronization software runs on the primary NSX Manager, synchronizing all universal objects to secondary NSX Managers.
