High-Performance Parallel Interface

High-Performance Parallel Interface
   Abbreviated HPPI. A parallel interface standard from the American National Standards Institute (ANSI) known as X3T9.3, originally developed as an interface between supercomputers and fast peripherals such as disk arrays and frame buffers.
   Recently, HPPI has been extended for use in networked computers and high-end workstations. It provides a data rate of 800Mbps over 32-pair twisted-pair copper wire, known as single HPPI, and 1,600Mbps over 64 pairs, known as double HPPI. Connection length is limited to 25 meters (82 feet).
