FortiNAC how many FNAC supported in a HA cluster

[Jucker]

Hello,

How many FNAC nodes supported by a single ha cluster does it support more than 2? i could not find this info in documentation.

Thanks and Regards!

FNAC HA cluster supports only two nodes in active/passive (in control) mode.The details are explained here: https://docs.fortinet.com/document/fortinac/9.4.0/high-availability

If you want more than one active node at a same time you should consider Distributed deployments that include also a FNAC Manger. More information can be checked on the deployment guide page 60: https://docs.fortinet.com/document/fortinac/9.4.0/deployment-guide

Hello ebilcari,

What i did understand without FNAC Control Manager we can't add more than two nodes into the deployment right ?

but the two nodes A/P only in control but the secondary node still can do application server ?

For the FNAC Manager we need a separated solution with its license for a future grown deployment ?

Thank you and regards!

Basically yes, without a Manager they will work as standalone independent nodes.

The deployments with separate roles, Control and Application are deprecated now and in this deployments four VMs/appliances were needed to build a HA, two (C + A) in control and two in standby. 

In CA deployments the roles run on same VM and can't be mixed between the HA nodes. One of the many benefits of the Manager are distributed licenses between the CAs.
