I think I just explained.
The standby databases are in a remote location. We want redundancy
there for two reasons:
1. for high availability during normal standby operations as the two
servers don't have HW support contracts
2. to have high availability already in place in case we have a
disaster. We can then startup using the servers we have, and add
more servers (which will be required to carry the load as more
applications will get on line again) without disrupting the operations
already in progress. As you know, you cannot move a single instance
database to a RAC config without shutting down the database.
