Clustering LiteSpeed Balancer

[iceyes]

Hi all,
is there a way to use 2 LiteSpeed balancer in a clustered configuration?
I have to setup a strong architecture so I'd like to know if I can setup LiteSpeed in a clustered configuration.

Thanks in advance

Yes, you can setup a HA cluster with Common Address Redundancy Protocol (CARP)

We have user doing this with FreeBSD + LSLB for HA solutions.

Great! Thank you very much for this information!
So, if I configure the 2 LiteSpeed with the same Load Balancer rules (rules on LiteSpeed1=rules on LiteSpeed2) and setup a Virtual IP using CARP, I'll refer to the Virtual IP and the Load Balancer rules will be automatically applied, right?
Have you some documentation, hints or example in order to setup this solution? It could be very helpful for me.
Thank you very much!

Yes, two load balancers will work in a HA manner.
We don't have tutorial on CARP + LSLB together. CARP is completely independent, you can google examples related to CARP setup.

There is a third party tutorial about LSLB in our wiki.

Thank you very much for your hints: I'll try to setup the described solution.
Thanks again!
