Disk Image and Deployment Size

SD-WAN Edge images are 40 GB by default. This is sufficient for client deployments that do not require WANOp functionality. If you require WANop feature or if you are installing an NCN system, you will need to increase the local file system size. Increases in size will be applied to the /home partition.The following table states disk size requirements for different installation types.

Table 2-1 Installation Types and Disk Space Requirements

Deployment Required Disk Space Manually add at least this much to /home
SD-WAN Edge Client 40 GB 0
SD-WAN Edge Client with WANOp 120 GB 80 GB
SD-WAN Edge as NCN 100 GB 60 GB
SD-WAN Edge as NCN with WANOp 180 GB 140 GB
When initially starting the SD-WAN virtual machines, the following volumes will be created:

When your deployment requires more space than the default image provides, increase the image size from the hypervisor after starting up the virtual appliance.
