Getting ready

The following are things to consider before deploying the NSX controller cluster:

• The controller cluster has three controllers in total and must be deployed in a cluster of three.
• Each controller node should reside on a separate ESXi host; DRS anti-affinity rules should be used to enforce this rule. It is generally recommended to deploy controllers on a vSphere cluster with a minimum of four ESXi hosts.
• Sufficient resources (vCPU, memory, and storage) on the vSphere cluster.
• NSX controller nodes should be deployed onto shared storage that is highly available.
• Each NSX controller requires an IPv4 address; these addresses are allocated via the NSX IP pool construct.
• NSX controllers require connectivity to NSX Manager and vSphere management VMKernel IP addresses.
• NSX controller should reside on a VLAN-backed PortGroup.

The NSX Controller IP Pool requires the following details prior to configuration. You can change values to suit your environment:
