RE: ASM - hardware mirroring vs. Oracle mirroring

One interesting variation is within a stretch cluster, where the capacity to read from a local mirror would probably be a significant benefit.
This *might* mean 11g ASM, or some other host based mirroring in preference to SAN level mirroring.

I understand that many people use ASM in conjunction with Symmetrix, etc., but I don't see how just pooling the storage and presenting it to the database is worth the effort (and the limitations, as there are certain operations in, e.g., RMAN, that aren't supported with ASM).
