Plus don't forget about ASRDF ( async ) where you don't take a performance hit
on log file sync / writes ... of course you have to be able to tolerate a small
amount ( or large ) amount of lost data.

Well, so, this is the eternal debate, yeah? Data Guard offers infinite
flexibility, the DBA can control everything, it's storage agnostic, you have
lots of knobs to twiddle, so on some levels that's perfect.
On the flip side though, SRDF is application/OS agnostic. Anything that gets
written to any SRDF'ed LUN, regardless of database, filesystem, OS, version,
etc. ends up on the far side. Like magic.
And SRDF is freakishly stable and mature. It's been baked and stable for 15
years.
