Forming an NSX Manager or Global Manager cluster provides high availability and reliability. Deploying nodes using the UI is supported only on ESXi hosts managed by VMware vCenter that is added as a compute manager.
For deploying additional NSX Manager nodes on a VMware vCenter that is not added as a compute manager, see Install NSX Manager on ESXi Using the Command-Line OVF Tool and Form an NSX Manager Cluster Using the CLI.
When you deploy a new node from the UI, the node connects to the first deployed node to form a cluster. All the repository details and the password of the first deployed node are synchronized with the newly deployed node. The first node is known as the orchestrator node because it contains the original copy of the VIBs and installation files required to prepare hosts of the cluster. The orchestrator node also help identify the node on which the Upgrade-Coordinator is running. When new nodes are added to the cluster, NSX uses the repository IP to synchronize the repository of VIBs and installation files on the new nodes of the cluster.
To create a Global Manager cluster, deploy two additional nodes to form a cluster of three nodes total. However, if your Global Manager has NSX 3.0.0 installed, deploy only one node, and do not form a cluster. See Install the Active and Standby Global Manager.
Prerequisites
- Verify that an NSX Manager or Global Manager node is installed. See Install NSX Manager and Available Appliances.
- Verify that compute manager is configured. See Add a Compute Manager.
- Verify that the system requirements are met. See System Requirements.
- Verify that the required ports are open. See Ports and Protocols.
- Verify that a datastore is configured and accessible on the ESXi host.
- Verify that you have the IP address and gateway, DNS server IP addresses, domain search list, and the NTP Server IP or FQDN for the NSX Manager to use.
- Create a management VDS and target VM port group in vCenter. Place the NSX appliances onto this management VDS port group network. See Prepare a vSphere Distributed Switch for NSX.
Multiple management networks can be used as long as the NSX Manager nodes has consistent connectivity and recommended latency between them.Note: If you plan to use Cluster VIP, all NSX Manager appliances should belong to same subnet.
