Content / Solution:

Server farms are groups (or pools) of networked real servers that contain the same content and that typically reside in the same physical location in a data center. Web sites often comprise groups of servers configured in a server farm. Load-balancing software distributes client requests for content or services among the real servers based on the configured policy and traffic classification, and server availability, and other factors. If one server goes down, another server can take its place and continue to provide the same content to the clients who requested it.

You can associate zero to many probes with a server farm.  By default, the real servers that you configure in a server farm inherit the probes that you configure directly on that server farm. Multiple probes that you configure on a server farm have an OR logic associated with them. If one of the probes configured on the server farm fails, the real server(s) that failed that probe enter the PROBE-FAILED state irrespective of the state of the other configured probes.

The load-balancing (Predictor) method that you configure determines how the loadbalancer selects a real server in a server farm to service a client request.  We currently offer 'Least Connections' and 'Round robin' load-balancing methods.

You can create your own Server Farms as described in How to Create a Server Farm on a Cloud Network in a MCP 1.0 Data Center Location, and then manage them as described in How to Manage a Server Farm in a MCP 1.0 Data Center Location
