Responders and Hot Spares

Responders provide functionality that automates the very basic functions of a hot spare server, and offloads them
onto Equalizer. If more functionality is desired, than a separate real server should be used as a hot spare for the
cluster.
It should also be noted that resources Equalizer uses to service client requests via the Responder feature are
resources potentially taken away from processing other client requests. In most cases, Responders might possibly
have an effect on performance if all the servers in one or more clusters are down during periods of peak usage.
