HIPPI (HIgh Performance Parallel Interface) is a
computer bus for the attachment of high speed storage devices to
supercomputers. It was popular in the late
1980s and into the mid-to-late
1990s, but has since been replaced by ever-faster standard interfaces like
SCSI and
Fibre Channel.The first HIPPI standard defined a 50-
wire twisted pair cable, running at 800 Mbit/s (100 MB/s), but was soon upgraded to include a 1600 Mbit/s (200 MB/s) mode running on
fibre optic cable. An effort to improve the speed resulted in HIPPI-6400, which was later re-named GSN (for Gigabyte System Network) but saw little use due to competing standards.
