Deploy NENs in a Supercluster
Important
This feature applies only to customers running Illumio Core 22.2.10. If you are running versions 22.2.x or earlier, this feature is unavailable.
Follow these guidelines when you deploy NENs in a Supercluster:
Where: You can pair NENs to Supercluster Members or to the Supercluster Leader. Deploy NENs as close as possible to the Server Load Balancers (SLBs) they're managing.
How many: A suggested maximum of three NENs per region, paired to the local PCE.
High Availability (HA): Depending on your scale requirements and the location of your network devices (such as SLBs), you can connect multiple NEN HA pairs to any cluster in a PCE Supercluster deployment (not just the PCE Supercluster leader). This is necessary in environments with many SLBs and virtual servers that are geographically distributed. For information about support for HA NEN deployments in general, see NEN HA Support.
