I'm interested in setting up UIM in my environment and I would like to know how many servers I need to get this up and running.
I did get a chance to read the section on Installation and Preparation in (CA Unified Infrastructure Management - 8.1 - CA Unified Infrastructure Management - 8.1 - CA Wiki) but soon got confused with the terminology of Hubs and Robots. At the moment, I am assuming Hubs to be the main UIM server and Robots to be the agent servers, I don't even know if my assumptions are correct.
My initial plans are to monitor 50 servers. How many servers do I need? Do I need to purchase database server?
If this turns out to be successful, and I grow to 500+ servers, what are my options for growth?.... Redo everything or just add more servers?
Any help, comments, suggestions greatly appreciated.
