Is it possible to cluster 2 stingray load balancers with different licenses?
For example. The primary Load Balancer is licensed and the secondary load Balancer is in Developer mode?
Solved! Go to Solution.
Technically, it is possible but the end result could lead to lot of issues based on automatic config replication across both the STMs.
Also, the bandwidth is not the same on both.
When you do this kind of clustering, to be consistent and to run without warnings/errors, the configuration should adhere to the features and bandwidth of the developer mode STM and not the fully licensed one.
It is totally possible to cluster two STM's with different licenses. The behaviour is sensible: both traffic managers will drop to the lowest common denominator of features between the two devices (this is what you would want, as you would not want a failover to happen and have the second STM NOT have the features needed for the configuration)
I am *mostly* sure that the different bandwidth limits on each cluster node are kept at the licensed level for that node (ie: you can have one STM with 1Gb of license, another with 2Gb for example) but I would need to test this to be sure. (this can be tested pretty quickly)
