The server farm is a logical entity made up of multiple real servers. You configure a server farm by naming it and populating it with real server members. A virtual server will use the server farm to select a real server to send requests to. A server farm can be configured to any number of virtual servers. Each server farm is configured to use a load balancing algorithm. The load balancing algorithm determines the real server selection process for this server farm. The server farm defaults to a round robin load balancing algorithm.
