I've heard it said in those cases that "performance doesn't matter much". As you suggest, database replication provides one of those features, and Solaris ZFS has many of the data management features found in high end SANs. Perhaps we can get the best of both? In the end, I think SAN vs. server storage is a religious battle. - Luke
