Goran,
You got great inputs so far. Just a word of caution, the EMC replication is
at the array level and it has no knowledge about Oracle datablocks. If
there is a corruption (believe me, it happens) at the oracle datablock
level, storage array will not aware of that and propagates the corruption to
the secondary (or remote) SAN. You have to periodically validate the
readiness of the DR site when SAN mirroring is used.
You don't need to do this additional step when DG is used as it validates
blocks during transfer and recovery..
