In my opinion, SAN storage begs the question about whether OFA makes sense
anymore. If you can configurte the SAN storage so that all files are
striped across all disk, then everything is spread. And if the SAN is
mirrored, then just why are we working so hard?

Title: RE: OFA and Shared Storage
Greg,
I
agree that OFA is a great concept for basing your standards on. At least

things like control files are (almost) a thing of the past.
Uptime is only one thing, there are several other errors that might occur,
like IO controller errors, memory/CPU glitches and file system corruptions
