Create an NSX Edge Transport Node

You can add an NSX Edge VM to the NSX-T Data Center fabric and proceed to configure it as a NSX Edge transport node VM.

An NSX Edge Node is a transport node that runs the local control plane daemons and forwarding engines implementing the NSX-T data plane. It runs an instance of the NSX-T virtual switch called the NSX Virtual Distributed Switch, or N-VDS. The Edge Nodes are service appliances dedicated to running centralized network services that cannot be distributed to the hypervisors. They can be instantiated as a bare metal appliance or in virtual machine form factor. They are grouped in one or several clusters, representing a pool of capacity.

An NSX Edge can belong to one overlay transport zone and multiple VLAN transport zones. An NSX Edge belongs to at least one VLAN transport zone to provide the uplink access.

Note: If you plan to create transport nodes from a template VM, make sure that there are no certificates on the host in /etc/vmware/nsx/. nsx-proxy does not create a certificate if a certificate already exists.

Prerequisites

Transport zones must be configured. See Create Transport Zones.
Verify that compute manager is configured. See Add a Compute Manager.
An uplink profile must be configured or you can use the default uplink profile for NSX Edge nodes. See Create an Uplink Profile.
An IP pool must be configured or must be available in the network deployment. See Create an IP Pool for Tunnel Endpoint IP Addresses.

Procedure

From a browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
Select System > Fabric > Nodes > Edge Transport Nodes > Add Edge VM.
Type a name for the NSX Edge.
Type the Host name or FQDN from vCenter Server.
Select the form factor for the NSX Edge VM appliance.

To customize CPU and memory allocated to an NSX Edge VM appliance, tune the following parameters. However, for maximum performance NSX Edge VM appliance must be assigned 100% of the available resources .

Caution: If you customize resources allocated to the NSX Edge VM, turn back the reservation later on to 100% to get maximum performance.

Option	Description
Memory Reservation (%)	Reservation percentage is relative to the pre-defined value in the form factor. 100 indicates 100% of memory is reserved for the NSX Edge VM. If you enter 50, it indicates that 50% of the allocated memory is reserved for the Edge transport node.
CPU Reservation Priority	Select the number of shares to be allocated to an NSX Edge VM relative to other VMs that are contending for shared resources. The following shares are for an NSX Edge VM in Medium form factor: Low - 2000 shares Normal - 4000 shares High - 8000 shares Extra High - 10000 shares
CPU Reservation (MHz)	Caution: Unless you need fine grained control over CPU reservations, do not use this field. Instead, change CPU reservations from the CPU Reservation Priority field. The maximum CPU reservation value must not exceed the number of vCPUs multiplied by the normal CPU operation rate of the physical CPU core. If the MHz value entered exceeds the maximum CPU capacity of the physical CPU cores, the NSX Edge VM might fail to start even though the allocation was accepted. For example, consider a system with two Intel Xeon E5-2630 CPUs. Each CPU contains ten cores running at 2.20 GHz. The maximum CPU allocation for a VM configured with two vCPUs is 2 x 2200 MHz = 4400 MHz. If CPU reservation is specified as 8000 MHz, the reconfiguration of the VM completes successfully. However, the VM fails to power on.

Description

Memory Reservation (%)

Reservation percentage is relative to the pre-defined value in the form factor.

100 indicates 100% of memory is reserved for the NSX Edge VM.

If you enter 50, it indicates that 50% of the allocated memory is reserved for the Edge transport node.

CPU Reservation Priority

Select the number of shares to be allocated to an NSX Edge VM relative to other VMs that are contending for shared resources.

The following shares are for an NSX Edge VM in Medium form factor:

Low - 2000 shares
Normal - 4000 shares
High - 8000 shares
Extra High - 10000 shares

CPU Reservation (MHz)

Caution: Unless you need fine grained control over CPU reservations, do not use this field. Instead, change CPU reservations from the CPU Reservation Priority field.

The maximum CPU reservation value must not exceed the number of vCPUs multiplied by the normal CPU operation rate of the physical CPU core.

If the MHz value entered exceeds the maximum CPU capacity of the physical CPU cores, the NSX Edge VM might fail to start even though the allocation was accepted.

For example, consider a system with two Intel Xeon E5-2630 CPUs. Each CPU contains ten cores running at 2.20 GHz. The maximum CPU allocation for a VM configured with two vCPUs is 2 x 2200 MHz = 4400 MHz. If CPU reservation is specified as 8000 MHz, the reconfiguration of the VM completes successfully. However, the VM fails to power on.

In the Credentials window, enter the following details.
- Specify the CLI and the root passwords for the NSX Edge. Your passwords must comply with the password strength restrictions.
  - At least 12 characters
  - At least one lower-case letter
  - At least one upper-case letter
  - At least one digit
  - At least one special character
  - At least five different characters
