Hi Jon,
One scenario I know that one of our very large customers is using
is to have dual servers discover the entire network. After the discovery
have each manage only one half of the network and each other. A couple
of times a day, sync up the DB's. If either server fails ( daemons fail to
satisfy a health check ) then the other server picks up management of
the former's half of the network. All clients are switched over to the
working server by customized scripts. This is a high level overview of
the process, but I think you will get the idea. The idea is to cut down
on cpu utilization by distributing workload across a couple of CPU's,
as well as create a robust failover system. You always have a working
backup server by the nature of both servers being both primary and
backup. This scenario doesn't depend on a static backup server that
may or may not work during a failover switch. You know that both
servers are working from the first discovery on.
I have a PowerPoint presentation on this that I gave at Planet Tivoli Paris.
If you would like to see it, then send me an email to the address at the
bottom of this email.
