Tiger Shark File System


Tiger Shark is a parallel file system for IBM's AIX Operating System that has been developed at the IBM Research - Almaden. Tiger Shark is designed to support interactive multimedia, particularly large-scale systems such as interactive television (ITV). Tiger Shark scales across the entire RS/6000 product line, from small desktop machines to the SP-2 parallel supercomputer. The recently-announced IBM Multimedia LAN Server for AIX is based on the Tiger Shark file system.

Tiger Shark Customer Trials and Joint Studies include:

Bell Atlantic Video on Demand Field Trial
Shark (a predecessor of Tiger Shark) on an RS/6000 delivering 50 simultaneous 1.5Mbit/sec MPEG streams via ADSL to 400 field trial participants in Alexandria, VA (1993-1994).
Hong Kong Telecom Video on Demand Trial
Tiger Shark on three RS/6000s delivering 150 simultaneous 1.5Mbit/sec streams via ADSL to trial customers (1995).
Argonne National Labs
Tiger Shark on a 28-node SP-2 delivering 4.5Mbit/sec M-JPEG video to workstation clients via an ATM WAN (MBone) using a modified version of the VIC conferencing system. This system was demonstrated at Supercomputing '95.
Indiana University School of Music Library
Variations Project - a digital library project using Tiger Shark on an RS/6000 to deliver digital audio and video to 130+ PC and Mac clients over an ATM network via NFS protocol.
