The Prisma SD-WAN Virtual ION on KVM for Network Functions Virtualization (NFV) Deployment Guide focuses specifically on deployment on standard NFV deployments. NFV can be instantiated and in many different forms and Prisma SD-WAN deployed on top of the NFV environment.

A virtual ION device can be deployed to an NFV host and assigned to either a branch or data center type of site. The design and deployment considerations are different between a branch and data center site. The VM deployment options such as the number of interfaces needed for the VM, how the virtual network interfaces are bound to physical NICs, etc. will vary based on these requirements. The following figure shows an example of a branch deployment where the virtual ION device is the WAN router terminating the MPLS and internet circuits.

To successfully deploy and configure Prisma SD-WAN in an NFV environment the vION model type and role should be determined prior to implementation. Download the latest release image from Palo Alto Networks and for sizing and resources requirements, refer to the SD-WAN datasheet and the Prisma SD-WAN documentation.

In summary, the supported NFV environment must meet the following requirements.

Deploy in standard NFV deployments, some examples are as follows:

The Server or the generic uCPE hardware must meet the following requirements:

In order to facilitate the deployment of Prisma SD-WAN ION devices to an NFV host, Prisma SD-WAN provides the virtual image in a qcow format per model type.
