  I heard somewhere that the 25MB/s interface isn't even FCAL (beyond
the obvious incompatibility you mentioned above, that is)...is there
any truth to this?

  On the subject of FCAL...I'm about to light up an A5100 on an Ultra30
with a QLA2100.  I've never managed an FCAL-based system before, and
the I/O performance of this system is going to be rather
critical...can anyone offer any tips for performance tuning and/or
monitoring?  The system is running Solaris7, with which I'm also
somewhat unfamiliar...I'm a BSD guy.
