Configuring the WSM using Device Manager

Minimum Misses

The minimum misses metric is optimized for Application Redirection. The minimum misses metric uses the IP address in the client request to select a server. As described below, the minimum misses metric uses either the client's source or destination IP address.

For Application Redirection, requests for a specific client destination IP address are sent to the same server. This metric helps maximize successful cache hits. Best statistical load balancing is achieved when the IP address destinations of load-balanced frames are spread across a broad range of IP subnets.
For SLB, the client source IP address and real server IP address are used. All requests from a specific client are sent to the same server.. This metric is useful for applications where client information must be retained on the server between sessions. With this metric, server load becomes most evenly balanced as the number of active clients with different source or destination addresses increases.

When selecting a server using the minimum misses metric, the WSM calculates a score for each available real server based on the IP address. The server that scores the highest is assigned the connection. This metric attempts to minimize the disruption of persistency when servers are removed from service. This metric should be used only when persistence is a must.

Note: The minimum misses metric cannot be used for firewall load balancing, since the real server IP addresses used in calculating the score for this metric are different on each side of the firewall.
