I'd have to agree with you about the specific SAN/setup you're working
with there. I certainly disagree that it's a general property of SAN's
though. We've got a DS4300 with FC controllers and drives, hosts are
generally dual-controller load-balanced and it works quite decently.

Indeed, the EMC SANs are generally the high-priced ones too, so not
really sure what to tell you about the poor performance you're seeing
out of it. Your IT folks and/or your EMC rep. should be able to resolve
that, really...

Enjoy,
