"internal" (not a good name) plugins are locked in memory on start in order to have them function even in situations when memory is tight. So, they are a bit better than external plugins. But nowadays, with enough memory, there's not much difference between the two. > I have > a SAN set up for fail-over, and everything looks like it is working as it > should.

It is good for testing only. If you have a SAN, you can try external/sbd.
