<p dir=3D=22ltr=22>Let me begin by deferring to The Big Brains, but I am =
not sure there's enough in this to really advise you from The =

I hear any db talking to a SAN, I get a bit leery. Couple that with =
replication, HA and failover=3F</p>
<p dir=3D=22ltr=22>If you could explain a bit more about what you're trying=

the issue.</p>
