ASM - hardware mirroring vs. Oracle mirroring
Date: Fri, 11 Apr 2008 08:33:36 -0500
I am starting to investigate ASM as a part of a potential 220.127.116.11 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?
