Nate,

Just asking is the fiber ports BiDirectional or Directional or can they
support a Bond that is BiDirectional of 4GB/s  or can they be trunked
into 16GB/s?  Bidirectional.   I need about 24 GB/s banwidth sustained,
yes per second.  Also what type of sparse file I/O you get .  I see you
stated multimode.  Some don't classify that as true BiDirectional
Bonding.
