I would carefully consider whether or not the _really_ need to be real time. Can you tolerate 5 minutes or even just 60 seconds of difference between them? If you can, then things are much easier and less complex. I'd personally use ZFS Snapshots to keep the two servers in sync every 60 seconds. As for load balancing, that depends on which protocal your using. FTP is easy. NFS/CIFS is a little harder. I'd simply use a load balancer (Zeus, NetScaler, Balance, HA-Proxy, etc.), but that is a little scary and bizarre in the case of NFS/CIFS, where you should instead use a single-server failover solution, such as Sun Cluster. benr. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
