When the FlexPar feature is enabled for an Intrepid 10000 Director,
the director is divided into multiple sub-directors, each operating
with independent management and services. This consolidates
application-based SAN islands, but does not enable device sharing
between the SAN islands (sub-directors). Inter-FlexPar routing
connects a SAN router to the Intrepid 10000 Director to enable
authorized (zoned) communication between FlexPars. This is a
unique application of SAN routing that enables communication
between sub-directors in the same physical chassis, as opposed to
routing between physically separate fabric elements.
