Peter,
Where in the documentation do you see Oracle having a bias towards ASM doing
mirroring?
I ask cause several Oracle folks I talked to, and an Oracle "best practices"
presentation I saw a while ago, all say the same thing. That being, if you
already have a well-designed SAN, use external redundancy in ASM, and let the
SAN do all the mirroring and striping.
That's where we're at, as well. SAN does all mirroring and striping. ASM just
pools the storage and makes it available to the database.

Subject: ASM - hardware mirroring vs. Oracle mirroring
I am starting to investigate ASM as a part of a potential 8.1.7.4 to 10g
upgrade on Solaris (SunOs 5.9). Oracle's documentation seems to have a bias
toward having the ASM instance handle the mirroring while our UNIX support
people would prefer to do it at the hardware level. Which is preferable and
what factors would push a decision in one direction or the other?
Thanks,
Peter Schauss
