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).
