Thanks Alan
Okay the PowerVM best practices says!
Remember the following technical constraints during your configuration:
The maximum number of VLANs per virtual adapter is 21 (20 VLAN IDs (VIDs) and 1 Port VLAN ID).
The maximum number of virtual adapters for each SEA is 16.
The maximum number of physical Ethernet adapters in a link aggregated adapter is eight for primary and one for backup.
The maximum virtual Ethernet frame size on the Power Systems server is 65,408 bytes.

Great question -
Normally I have seen , the SEAs are built out on the VIOS pair.
Then that compute node gets "ingested" into PowerVC where it brings in the VLANs. I do not think I have seen an upward limit within PowerVC.
Dropping in the PowerVM Best Practices Redbook for reference:

Hi All,
What is the maximum number of networks allowed in PowerVC.
The document says. "
3. In Shared Ethernet Adapter environments, if the network has a VLAN that is on the Shared Ethernet Adapter's primary virtual Ethernet adapter, PowerVC uses the existing VLAN. If no such VLAN exists, PowerVC adds and removes VLANs from the single shared Ethernet adapter as necessary.
Because there is a limit to the number of networks that you can associate with PowerVC, regularly remove any networks that you no longer use."
Assuming there is a limit set in neutron?
Warm Regards,
Sasi
