NSX Manager is installed as a virtual appliance on any ESXi host in your vCenter environment.
NSX Manager provides the graphical user interface (GUI) and the REST APIs for creating, configuring, and monitoring NSX components, such as controllers, logical switches, and edge services gateways. NSX Manager provides an aggregated system view and is the centralized network management component of NSX Data Center for vSphere. The NSX Manager virtual machine is packaged as an OVA file, which allows you to use the vSphere Web Client to import the NSX Manager into the datastore and virtual machine inventory.
For high availability, deploy NSX Manager in a cluster configured with HA and DRS. Optionally, you can install the NSX Manager in a different vCenter than the one that the NSX Manager will be interoperating with. A single NSX Manager serves a single vCenter Server environment.
In cross-vCenter NSX installations, make sure that each NSX Manager has a unique UUID. NSX Manager instances deployed from OVA files have unique UUIDs. An NSX Manager deployed from a template (as in when you convert a virtual machine to a template) has the same UUID as the original NSX Manager used to create the template. In other words, for each NSX Manager, you should install a new appliance as outlined in this procedure.
The NSX Manager virtual machine installation includes VMware Tools. Do not attempt to upgrade or install VMware Tools on the NSX Manager.
During the installation, you can choose to join the Customer Experience Improvement Program (CEIP) for NSX Data Center for vSphere. See Customer Experience Improvement Program in the NSX Administration Guide for more information about the program, including how to join or leave the program.
