Setting Description Use Case - Select Kubernetes - Workload Management to create an NSX Edge cluster that complies with the requirements for deploying vSphere IaaS Control Plane. See VMware Cloud Foundation with VMware Tanzu. If you select this option, you cannot modify the NSX Edge form factor or Tier-0 service high availability settings.
- Select Application Virtual Networks to create an NSX Edge cluster that complies with the requirements deploying VMware Aria Suite components. See Deploying Application Virtual Networks in VMware Cloud Foundation.
Note: Management domain only.
- Select Custom if you want an NSX Edge cluster with a specific form factor or Tier-0 service high availability setting.
Edge Form Factor - Small: 4 GB memory, 2 vCPU, 200 GB disk space. The NSX Edge Small VM appliance size is suitable for lab and proof-of-concept deployments.
- Medium: 8 GB memory, 4 vCPU, 200 GB disk space. The NSX Edge Medium appliance size is suitable for production environments with load balancing.
- Large: 32 GB memory, 8 vCPU, 200 GB disk space. The NSX Edge Large appliance size is suitable for production environments with load balancing.
- XLarge: 64 GB memory, 16 vCPU, 200 GB disk space. The NSX Edge Extra Large appliance size is suitable for production environments with load balancing.
Tier-0 Service High Availability In the active-active mode, traffic is load balanced across all members. In active-standby mode, all traffic is processed by an elected active member. If the active member fails, another member is elected to be active. Workload Management requires Active-Active.
Some services are only supported in Active-Standby: NAT, load balancing, stateful firewall, and VPN. If you select Active-Standby, use exactly two NSX Edge nodes in the NSX Edge cluster.
Tier-0 Routing Type Select Static or EBGP to determine the route distribution mechanism for the tier-0 gateway. If you select Static, you must manually configure the required static routes in NSX Manager. If you select EBGP, VMware Cloud Foundation configures eBGP settings to allow dynamic route distribution. ASN Enter an autonomous system number (ASN) for the NSX Edge cluster. (for EBGP only) - Enter the configuration settings for the first NSX Edge node and click Add Edge Node.
Setting Description Edge Node Name (FQDN) Enter the FQDN for the NSX Edge node. Each node must have a unique FQDN. Cluster Select a vSphere cluster to host the NSX Edge node. You can select a standard vSphere cluster or a stretched vSphere cluster, but all the NSX Edge nodes in an NSX Edge cluster must be hosted on vSphere clusters of the same type.
Note: If the vSphere cluster you select already hosts management virtual machines that are connected to the host Management port group, the VM Management Portgroup VLAN and VM Management Portgroup VLAN settings are not available.Cluster Type Select L2 Uniform if all hosts in the vSphere cluster have identical management, uplink, host TEP, and Edge TEP networks. Select L2 non-uniform and L3 if any of the hosts in the vSphere cluster have different networks.
Important: VMware Cloud Foundation does not support Edge cluster creation on L2 non-uniform and L3 vSphere clusters.First NSX VDS Uplink Click Advanced Cluster Settings to map the first NSX Edge node uplink network interface to a physical NIC on the host, by specifying the ESXi uplink. The default is uplink1. When you create an NSX Edge cluster, SDDC Manager creates two trunked VLAN port groups. The information you enter here determines the active uplink on the first VLAN port group. If you enter uplink3, then uplink3 is the active uplink and the uplink you specify for the second NSX VDS uplink is the standby uplink.
The uplink must be prepared for overlay use.
Second NSX VDS Uplink Click Advanced Cluster Settings to map the second NSX Edge node uplink network interface to a physical NIC on the host, by specifying the ESXi uplink. The default is uplink2. When you create an NSX Edge cluster, SDDC Manager creates two trunked VLAN port groups. The information you enter here determines the active uplink on the second VLAN port group. If you enter uplink4, then uplink4 is the active uplink and the uplink you specify for the first NSX VDS uplink is the standby uplink.
The uplink must be prepared for overlay use.
Management IP (CIDR) Enter the management IP for the NSX Edge node in CIDR format. Each node must have a unique management IP. Management Gateway Enter the IP address for the management network gateway. VM Management Portgroup VLAN If the VM Management port group exists on the vSphere distributed switch of the vSphere cluster that you selected to host the Edge node, then the VM Management port group VLAN is displayed and cannot be edited. If the VM Management port group does not exist on the vSphere distributed switch of the vSphere cluster that you selected to host the Edge node, enter a VLAN ID to create a new VM Management port group or click Use ESXi Management VMK's VLAN to use the host Management Network VLAN to create a new VM Management port group.
VM Management Portgroup Name If the VM Management port group exists on the vSphere distributed switch of the vSphere cluster that you selected to host the Edge node, then the VM Management port group name is displayed and cannot be edited. Otherwise, type a name for the new port group.
Edge TEP 1 IP (CIDR) Enter the CIDR for the first NSX Edge TEP. Each node must have a unique Edge TEP 1 IP. Note: It is possible to configure Edge TEPs using an NSX IP pool instead of static addresses. IP pools may only be specified when using the VCF API only, not the UI.Edge TEP 2 IP (CIDR) Enter the CIDR for the second NSX Edge TEP. Each node must have a unique Edge TEP 2 IP. The Edge TEP 2 IP must be different than the Edge TEP 1 IP. Edge TEP Gateway Enter the IP address for the NSX Edge TEP gateway. Edge TEP VLAN Enter the NSX Edge TEP VLAN ID. First Tier-0 Uplink VLAN Enter the VLAN ID for the first uplink. This is a link from the NSX Edge node to the first uplink network.
First Tier-0 Uplink Interface IP (CIDR) Enter the CIDR for the first uplink. Each node must have unique uplink interface IPs. Peer IP (CIDR) Enter the CIDR for the first uplink peer. (EBGP only) Peer ASN Enter the ASN for the first uplink peer. (EBGP only) BGP Peer Password Enter and confirm the BGP password. (EBGP only). Second Tier-0 Uplink VLAN Enter the VLAN ID for the second uplink. This is a link from the NSX Edge node to the second uplink network.
Second Tier-0 Uplink Interface IP (CIDR) Enter the CIDR for the second uplink. Each node must have unique uplink interface IPs. The second uplink interface IP must be different than the first uplink interface IP. Peer IP (CIDR) Enter the CIDR for the second uplink peer. (EBGP only) ASN Peer Enter the ASN for the second uplink peer. (EBGP only) BGP Peer Password Enter and confirm the BGP password. (EBGP only). - Click Add More Edge Nodes to enter configuration settings for additional NSX Edge nodes.
A minimum of two NSX Edge nodes is required. NSX Edge cluster creation allows up to 8 NSX Edge nodes if the Tier-0 Service High Availability is Active-Active and two NSX Edge nodes per NSX Edge cluster if the Tier-0 Service High Availability is Active-Standby.Note: All Edge nodes in the NSX Edge cluster must use the same VM Management port group VLAN and name.
- When you are done adding NSX Edge nodes, click Next.
- Review the summary and click Next.
SDDC Manager validates the NSX Edge node configuration details.
- If validation fails, use the Back button to edit your settings and try again.
To edit or delete any of the NSX Edge nodes, click the three vertical dots next to an NSX Edge node in the table and select an option from the menu.
- If validation succeeds, click Finish to create the NSX Edge cluster.
You can monitor progress in the Tasks panel.
