<p dir="ltr">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 Implementation Guys. That's me. I/O for any database is an issue, and when I hear any db talking to a SAN, I get a bit leery. Couple that with replication, HA and failover?</p>
<p dir="ltr">If you could explain a bit more about what you're trying to accomplish, what expected performance should be, how that SAN is actually utilized, and such, I might be able to provide some experience on the issue.</p>
