The multipath option definitely deserves more investigation.  I had one
person tell me they're using it already, to connect ESXi to ZFS backend
storage, but it's a new feature in Solaris 11 Express, and it's only
applicable to ISCSI.  By expanding to 2 ports instead of 1, he got nearly
double the speed.  All these "facts" need verification.  And I'm sure there
are plenty of limitations and gotchas to be aware of.  ;-)  Particularly,
"only iscsi."  While not necessarily fatal, that's certainly undesirable in
some cases.
