What kind of server you want to integrate ? You mean additional sever for publish or cluster ? Can you please be more specific ?
Thanks for ur reply . I would like to integrate openX ad server in CQ.
I have zero experience with this. I am guessing for openX ad server install the openxsourcerestapi there by exposes rest api & CQ exposes a RESTful API for the underlying JCR. With this seems can be integrated.
