Yes. I have deployed HA clusters with FreeBSD using
Alteon [*] boxes (Nortel). They support both HA and
load balancing. Work very well with farms of web
servers, mail servers etc.
Getting NFS to work in a HA environment is rather a
black art. I recommend third party products such as
NetApp Filers which support HA cluster setups. And
their OS is BSD-based, too, so it's not totally off-
PostgreSQL comes with replication tools which are OS-
independant, they work well, too. There's similar
stuff for MySQL, but it doesn't work as well as
PostgreSQL. Well, at least that's my impression.
PS: [*] Alteon Networks (not yet Nortel at that time)
produced a nice print ad in 1999. Unfortunately it
never went into actual print ... Dunno why ... :-)
That web page contains a comment by Jordan Hubbard,
by the way. I'm not sure if it's "our" FreeBSD JKH,
