VMware NSX-T Global Manager Appliance Install

One of the really great new features of NSX-T 3.0 and higher is the introduction of the Global Manager appliance. With the global manager appliance, you have access to the really cool new features in NSX-T 3 such as NSX Federation. In this post, let’s take a quick look at VMware NSX-T global manager appliance install and getting started adding your NSX-T managers to the global manager.

What is NSX-T Data Center Federation?

With NSX-T Data center federation, you can manage multiple NSX-T data center environments from a single dashboard for seamless management. This allows creating gateways and segments that span more than one location as well as creating/enforcing firewall rules across locations. This simple addition to the NSX-T 3.0 release is extremely powerful and gives networking and security admins what they have been asking for quite some time with NSX-T.

A Federation environment includes two types of management systems:

  • Global Manager: a system similar toΒ NSX ManagerΒ that federates multiple Local Managers.
  • Local Manager: anΒ NSX ManagerΒ system in charge of network and security services for a location.

Regarding configuration, a couple of points to note:

  • Configurations that are created on the Global Manager are read-only on the Local Managers. Configurations on the Local Managers are not synced with the Global Manager.
  • The Global Manager syncs a configuration with a Local Manager only if the configuration is relevant to that location. For example, if you create a tier-0 gateway and add it to Location 1, Location 2, and Location 3, the configuration is synced with all three Local Managers.
