HIPPI is a computer bus standard for high-speed transfer of large amounts of data over short distances between supercomputers and storage devices. It uses point-to-point links and circuit switching to transfer data at speeds up to 1600 Mbps using copper cables up to 25 meters or up to 6400 Mbps using fiber optic cables up to 10 kilometers. HIPPI employs star-hub switches to provide connectivity and transfers data in bursts of 1024 or 2048 bytes over unidirectional channels.

2. About HIPPI
 High Performance Parallel Interface
 Computer bus for attachment of high speed
storage devices to supercomputers.
 Standard CO, point-to-point protocol for
transmitting large amount of data over short
distances
 Uses point-to-point link & circuit switching
technology
 Original HIPPI standard specifies data transfer
at 800 Mbps with 32-bit data bus or 1600 Mbps
with 64-bit data bus

3. About HIPPI (continued)
 The first HIPPI standard defined a 50-wire
twisted pair Cu cables running at 800 Mbps with
a maximum range of 25 m
 Data is sent in burst of 1024 or 2048 Bytes on a
unidirectional channel
 It uses a 4x4 crossbar network switch that
allows data to be forwarded
 Provides error detection and no error correction

up to 10 km using optic fiber cables
 HIPPI-6400 or GSN (Gigabyte System
Network) promises up to 6400 Mbps of
data transfer speed, full-duplex
bandwidth
