The following are things you need to consider before pairing the NSX Manager with the vCenter server:
- Solution interoperability has been verified
- vCenter server and vSphere environment are in a healthy state
- Platform Services Controller (PSC) Fully Qualified Domain Name (FQDN) can be resolved
- vCenter server FQDN can be resolved
- vCenter and PSC time settings are verified
- A service account with administrator role in vCenter has been created for the NSX Manager to use for registration; for further information refer to Chapter 9, Managing User Accounts in VMware NSX
- TCP port 443 connectivity is required from the NSX Manager to the platform services controller and the vCenter server
vCenter server and platform services controller high availability options have been consulted to ensure the vCenter and PSC environment are set up as per VMware recommendations. For further information on supported vCenter high availability options, refer to the VMware KB article 1024051 (https://kb.vmware.com/kb/1024051).
