PKS only supports NSX-T Edge Node VM configurations that are large in size. PKS only supports one Edge Cluster instance of T0 (8 vCPU, 16 GB RAM). The T0 router must be configured in Active/Standby mode, as SNAT rules will be applied there by PKS. An NSX-T Edge Cluster can contain up to eight Edge Transport Nodes (TN). You can add new Edge Nodes (up to eight) in the Edge Cluster to increase the overall capacity (LB, for instance) and provide scalability to the NSX-T Edge Cluster. You can use two different Edge Nodes for the T0 uplinks IP addresses (two IPs in total) to provide HA to NSX-T T0 in an Edge Cluster. We should enable HA VIP on T0 so that it's always operational, even if one T0 uplink is down. The physical router will only interoperate with the T0 HA VIP.
The following are the NSX-T and load balancer scale numbers:
