Joshua,

I've heard this before, but I couldn't find anyone at IBM to confirm it.
SO.........

I've been running tape and dasd thru the same FC adapter for about a year
now.  Traffic goes from rs6k to an IBM2109 (brocade) switch and then spli=
ts
from there.  I suspect the switch is handling the arbirated loop (3590) a=
nd
point to point (ess aka shark) communication conversions.

Gotchas?

Not only is sending disk and tape data across the same FC card a bad idea=
, I
believe IBM doesn't even support that configuration.
