What we do is have some sort of central storage. We use netapp for that (and on another setup we have a HA NFS server based on linux with drbd to do the sync of the data between the two NFS servers) A bunch of boxen is mounting this storage using NFS and running the services. A pair of OpenBSD firewalls with relayd is doing the loadbalancing/failover stuff. -- Michiel van Baak [EMAIL PROTECTED] http://michiel.vanbaak.eu GnuPG key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x71C946BD "Why is it drug addicts and computer aficionados are both called users?"
