Max number of clients per AOS vs. max number of client sessions per AOS

Hi,

I want to setup an AOS cluster without any dedicated load balancer like described on the following TechNet site:

http://technet.microsoft.com/en-us/library/dd362108.aspx

This means, that every AOS acts as an active application server or routes the client request to the next AOS available when the maximum number of clients has reached.

How can I configure the maximum number of clients? Is this equal the "MaxConcurrentUISessions" value in the cluster configuration setup?

How can I get the actual number of clients in the "online users window"?

There we have two different values: the "active users" on the front tab and the number of clients on the "server instance" tab. How theese values correlate?

How can I find out and configure "my" value?

Thanks for any suggestions,

Hans-Peter
