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- topic. 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. Best regards Oliver 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 ... :-) http://www.zeldman.com/adgraveyard/6.html That web page contains a comment by Jordan Hubbard, by the way. I'm not sure if it's "our" FreeBSD JKH, though. -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
