Adjusting Advanced Settings
Click
the Magnify icon to view the NAS Administrator.
The Advanced Setting Tab allows the administrator to configure how the
load-balancing information is gathered and shared.
Base Broadcast/Update Interval
This
is also known as the heartbeat broadcast. Each server rebroadcasts
its Application Component and Server Load information at the interval
set for the Base Broadcast/Update Interval. If any NAS missed the other
broadcast interval, it would have the information after the heartbeat
broadcast is sent.

Max Hops
Application
Component requests have a hop count associated with them that increments
each time the Application Component request is moved from one server
to another.
The hop count setting for a server states that any incoming Application
Component requests with a hop count equal to or greater than the hop
count set for that server cannot be load balanced to another server.
