I'm basically just a user of the capability, how much detail do you
want? It's just the standard failover built into bb.

How the hostname reflects to what IP address? I'm not sure what you
mean. There are no tricks here, just the standard dns naming scheme.
I'm not sure what hardware has to do with it, but we're running SLES on
HP/Compaq DL servers.
I'm not sure what you mean by "what software" - you mean the OS, or the
applications being monitored, or the exact version of bb?

We're on 1.9 here, patched with bbgen to keep it going - AFAIK the bb
code has basically languished since it was bought back in 2001 or so, so
I'm curious about this version 3.3 that you speak of.

Yes, those discussions look mostly like the typical ha requirements,
e.g. managing bb failover via external proxies, redirectors etc, which
adds a whole new layer of cost and complexity. It would be a hard sell
to justify all the new ha infrastructure if we are replacing bb with
something newer and better, since bb currently handles that all by
itself, with no need of an external ha system.
