This document describes IRIS HIPPI products for IRIX 6.4 (or later).

The IRIS® HIPPI product is a network interface controller board (hardware) and driver and utilities (software) providing data communication through the High–Performance Parallel Interface (HIPPI). The product provides copper-based HIPPI-PH connectivity for CHALLENGE® L and XL, and Onyx® platforms, and fiber-optic based HIPPI-Serial connectivity for the OriginServer series and Onyx2 platforms.

The IRIS HIPPI hardware must be installed by a Silicon Graphics system support engineer (SSE) or other person trained by Silicon Graphics. The installation instructions (shipped, in a sealed envelope, with each IRIS HIPPI board) contains complete details for hardware installation. The seal on the envelope must not be broken by anyone except the SSE. For Challenge and Onyx systems, use the IRIS HIPPI Board Installation Instructions; for Origin and Onyx2 systems, use IRIS HIPPI-Serial XIO Board Installation Instructions.

Installation and configuration of the software on all platforms can be done by customers and/or SSEs. This document, IRIS HIPPI Administrator's Guide (shipped with the IRIS HIPPI software), provides software configuration details. The online IRIS HIPPI Release Notes provide software installation instructions and late-occurring information about the product.

Support for Upper Layer Applications

IRIS HIPPI supports the following upper layer applications:

  • standard IRIX applications:
    For Internet (IP) networking, IRIS HIPPI supports IP over HIPPI-LE in conformance with RFC 1374 guidelines. All IP applications can use the IP–over–HIPPI interface, just as they would IP over Ethernet or FDDI.

  • IRIS HIPPI utilities:
    IRIS HIPPI includes utilities for monitoring, maintaining, and testing the IRIS HIPPI subsystem.

  • customer-developed applications:
    IRIS HIPPI provides an application programming interface (API) that customers can use to develop their own upper–layer applications (ULPs). See the online IRIS HIPPI API Programmer's Guide (shipped with the IRIS HIPPI software) for details.
