  HIPPI is used for lots of things.  There are HIPPI disk arrays,
HIPPI frame buffers, etc etc.  It's very fast, and very low-latency.
It typically shows up on a machine as a network interface.

  HIPPI runs at varying speeds.  100MBps is the slowest.

  HIPPI is wonderful and manly.  Lots of information can be found at
