Well, that's just another distinction for clusters. Most of the time it's between Shared-Disk vs. Shared-Nothing. You could also see the very Big Irons as a Shared-Everything Cluster. While it's certainly true, that any kind of data partitioning for databases only make sense for Shared-Nothing Clusters, I don't think it's a 'kind of replication'. AFAIK most database replication solutions are built for Shared-Nothing Clusters. (With the exception of PgCluster-II, I think). Regards Markus
